FOR THE THREEAND NINE MONTHS ENDEDSEPTEMBER 30, 2013

 	1	“Gold equivalent ounces” includes silver ounces produced, and converted to a gold equivalent based on a ratio of the average commodity prices received for each period. The ratio for the third quarter 2013 was based on realized prices of $1,338 per ounce of gold and $8.42 per ounce of silver.	
 	 	 	
 	2	Total cash costs per gold equivalent ounce and total cash costs per gold ounce on a by-product basis are non-GAAP measures. Total cash costs per gold equivalent ounce are defined as costs of production (including refining costs) divided by the total number of gold equivalent ounces produced. Total cash costs per gold ounce on a by-product basis are calculated by deducting the by-product silver credits from operating costs and dividing by the total number of gold ounces produced. The Company reports total cash costs on a production basis. In the gold mining industry, these are common performance measures but do not have any standardized meaning, and are non-GAAP measures. As such, they are unlikely to be comparable to similar measures presented by other issuers. In reporting total cash costs per gold equivalent and total cash costs per gold ounce on a by-product basis, the Company follows the recommendations of the Gold Institute standard. The Company believes that, in addition to conventional measures, prepared in accordance with GAAP, certain investors use this information to evaluate the Company’s performance and ability to generate cash flow. Accordingly, it is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. Refer to “ Non-GAAP measure – Total cash costs per gold ounce ” below for a reconciliation of cash costs per gold ounce on both a by-product and gold equivalent basis to reported operating expenses (the most directly comparable GAAP measure).	
 	 	 	
 	3	The Company, in conjunction with an initiative undertaken within the gold mining industry, has adopted an all-in sustaining cost non- GAAP performance measure that the Company believes more fully defines the total cost associated with producing gold; however, this performance measure has no standardized meaning. Accordingly, it is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. The Company reports this measure on a gold ounces produced basis. Refer to “ Non-GAAP measure – All-in sustaining costs per gold ounce ” below for a reconciliation of all-in sustaining costs per gold ounce.	
 	 	 	
 	4	Adjusted net income and adjusted net income per share are non-GAAP measures. Adjusted net income is net income adjusted for unusual items. Neither of these non-GAAP performance measures has any standardized meaning and is therefore unlikely to be comparable to other measures presented by other issuers. The Company believes that, in addition to conventional measures prepared in accordance with GAAP, certain investors use this information to evaluate the Company’s performance. Accordingly, it is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. Refer to “ Non-GAAP measure – Adjusted net income” below for a reconciliation of adjusted net income to reported net income.

MANAGEMENT’S DISCUSSION ANDANALYSIS
FOR THE THREEAND NINE MONTHS ENDEDSEPTEMBER 30, 2013
OVERVIEW
Primero is a Canadian-based precious metals producer with operations in Mexico. The Company is focused on building a portfolio of high quality, low cost precious metals assets in the Americas through acquiring, exploring, developing and operating mineral resource properties. The Company currently owns one producing property, the San Dimas gold-silver mine, mill and related assets (the “San Dimas Mine”), located in Mexico’s San Dimas district, on the border of Durango and Sinaloa states, a 69.2% interest in one gold-silver-copper project in the development stage, Cerro del Gallo, located in state of Guanajuato in central Mexico and one exploration property, Ventanas, located in Durango state, Mexico
The Company’s shares are listed on the Toronto Stock Exchange (“TSX”) under the symbol “P”, on the New York Stock Exchange (“NYSE”) under the symbol “PPP” and on the Australian Securities Exchange (“ASX”) under the symbol “PPM”. In addition, Primero has common share purchase warrants which trade on the TSX under the symbol “P.WT”. On October 14, 2013, the Company announced that ASX Limited approved the Company’s request for its removal from the official list of the Australian Securities Exchange. The Company's decision was based on the low volume of trading of its CHESS Depositary Interests ("CDIs") on the ASX compared to common shares on the TSX and NYSE. Since listing on the ASX in May 2013, the CDIs held on the Australian register have declined from approximately 14% of the Company’s total issued share capital to less than 7% as at October 1, 2013. As a result, the Company determined that sustaining the administrative and compliance costs of an ASX listing was not in the interests of Primero and all of its shareholders. The date on which the Company will be removed from the official list will be December 30, 2013. Details of the delisting process were mailed to CDI holders on October 24, 2013, and are available on the Company’s website.
With the recent addition of the Cerro del Gallo development project, through the acquisition of Cerro Resources NL (“Cerro”), Primero is well positioned as an emerging mid-tier gold producer. The Company believes that the San Dimas mine provides a solid production base with short-term opportunities to optimize mine capacity, increase mill throughput and expand production. The addition of the Cerro del Gallo project increased the Company's reserves and resources and could potentially deliver an additional 95,000 gold equivalent ounces (based on 100% ownership) per year of production. Primero is focused on optimizing the San Dimas mine, making a construction decision at Cerro del Gallo by the end of 2013 and, if appropriate, making further acquisitions of precious metal properties in low risk regions of the Americas.
RECENT CORPORATE DEVELOPMENTS
Consolidation of Cerro del Gallo ownership
The Company has entered into a binding letter of intent with a subsidiary of Goldcorp Inc. to acquire the remaining 30.8% interest in the Cerro del Gallo project. The closing date for the acquisition (the “Closing Date”) is expected to be before December 31, 2013. The consideration comprises an upfront payment of $8 million, plus contingent payments based on meeting certain milestones or market conditions. The contingent payments include $8 million (the “First Contingent Payment”) after achieving commercial production on the Phase I heap leach operation; $5 million if the date of the First Contingent Payment occurs before the fifth anniversary of the Closing Date and the gold price averages $1,500 per ounce for a consecutive 30 day period within one year following the date of the First Contingent Payment, and not later than the fifth anniversary of the closing date; $14 million (“the Second Contingent Payment”) on announcement of a decision by Primero to construct a carbon-in-leach mill for Phase II, and $5 million if the date of the Second Contingent Payment occurs before the fifth anniversary of the Closing Date and the gold price averages $1,500 per ounce for a consecutive 30 day period within one year following the date of the Second Contingent Payment, and not later than the fifth anniversary of the closing date.

PRIMERO MINING CORP.
MANAGEMENT’S DISCUSSION AND ANALYSIS
FOR THE THREE AND NINE MONTHS ENDED SEPTEMBER 30, 2013
The acquisition of the remaining 30.8% interest in Cerro del Gallo consolidates the Company’s position in its only development project, extinguishes the joint venture agreement thereby reducing administrative costs and eliminates a potential 10% net profit interest.
Cerro del Gallo project update
Following the acquisition of the Cerro del Gallo project in May 2013 the Company commenced an assessment of the alternatives for the long term development of the project. The May 2012 Definitive Feasibility Study ("DFS")¹ on the project contemplated only a phase one ("Phase I") heap leach of 4.5 million tonnes per year of oxidized and partially oxidized ore for 7.2 years of production. The May 2012 DFS superseded an earlier preliminary assessment in May 2011, that identified a potential phase two ("Phase II") addition of carbon-in-leach ("CIL") processing of fresh rock commencing in the fifth year. The Company is considering design alternatives which include a heap leach only operation (Phase I), an accelerated timetable for the CIL processing facility (Phase II) and a CIL only operation. The key elements of the assessment will be the trade-off between capital and metal recovery as well as the impact of various processing approaches to the reserve and resource base. Further drilling is part of this assessment program and will focus on the detailed metallurgical characterization of the transition zone as well as the unoxidized mineralization at depth and lateral to the ore zone currently considered in the Phase I development plan. The exploration work also being conducted concurrently will be an important component for the development decision.
As a result of the significant decline in the gold price and the recent tax reforms in Mexico, the Company elected to critically review and refine the capital expenditures for the development of the Cerro del Gallo project. The Company’s 2013 budget for Cerro del Gallo is $15 million including $4 million for exploration and condemnation drilling. This spending is expected to be sufficient to complete all outstanding permitting, land acquisition, basic engineering of the mine processing facilities and a preliminary exploration program, including condemnation drilling. The Company expects to be in a position to make a construction decision by the end of 2013. For more details see “Liquidity outlook - Capital expenditures for the Cerro del Gallo project” below.

PRIMERO MINING CORP.
MANAGEMENT’S DISCUSSION AND ANALYSIS
FOR THE THREE AND NINE MONTHS ENDED SEPTEMBER 30, 2013
OUTLOOK FOR 2013 REVISED UPWARD FOR A SECOND TIME
The following represents forward-looking information and users are cautioned that actual results may vary. Based on better than expected operating results in the third quarter, Primero has increased its production guidance to between 135,000 and 140,000 gold equivalent ounces, up to 26% higher than 2012, based on higher throughput at higher grades. The Company now expects its gold production to be in the range of 105,000 and 110,000 ounces. Cash costs for 2013 are expected to be at the lower end of the guidance range of $620 to $640 per gold equivalent ounce and between $410 and $430 per gold ounce on a by-product basis.
Primero's 2013 revised outlook is summarized in the following table:

 	2012 Actuals	Outlook 2013	Outlook 2013	Outlook 2013	
 	 	(original)	(revised -Q2 2013)	(revised - Q 3 2013)	
Attributable gold equivalent production	 	 	 	 	
(gold equivalent ounces)	111,132	120,000-130,000	125,000-135,000	135,000-140,000	
Gold production (ounces)	87,900	90,000-100,000	95,000-105,000	105,000-110,000	
 	 	 	 	 	
Silver production (ounces)	5,134,184	6,000,000-6,500,000	5,600,000-6,000,000	5,600,000-6,000,000	
Total cash costs (per gold equivalent ounce)	$636	$620 -$640	$620 -$640	$620 - $640	
Total cash costs -by-product (per gold ounce)	$366	$280 -$300	$410 -$430	$410 - $430	
Material assumptions used to forecast total cash costs for 2013 include: an average gold price of $1,410 per ounce, revised downwards from the original estimate of $1,700 per ounce; an average silver price of $6.77 (revised downwards from $8.52) per ounce (calculated using the silver agreement contract price of $4.14 per ounce and assuming excess silver beyond contract requirements is sold at an average silver price of $21.16 per ounce revised downwards from $30); and foreign exchange rates of 1.00 Canadian dollars and 13 Mexican pesos to the US dollar.
Capital expenditures at San Dimas are expected to be approximately $45 million (revised upwards from $42 million in August 2013) excluding capitalized exploration expenses of $15 million.
Underground development at San Dimas in 2013 is focused in the main mining (Central Block and Sinaloa Graben) blocks. In 2013 the majority of the ore is anticipated to come from the Central Block with approximately 30% from the higher-grade Sinaloa Graben block.
Capital expenditures for the Cerro del Gallo project are expected to be approximately $15 million in 2013 based on 100% ownership. The Company plans to complete all outstanding permitting, land acquisition, basic engineering of the mine processing facilities and a preliminary exploration program, including condemnation drilling. The Company expects to make a construction decision on the Cerro del Gallo project by the end of 2013. Assuming that a decision is made to proceed with construction, the Company expects to commence production at Cerro del Gallo by the end of 2015. This would represent a delay of approximately six months compared with the Company’s original plan.

San Dimas produced 31,791 ounces of gold and 1.62 million ounces of silver in Q3 2013, 68% more and 42% more, respectively, than Q3 2012. The increase in gold production was due to 12% higher throughput in Q3 2013 than Q3 2012, and a 49% increase in average mill head grade. Silver grades increased 26% in Q3 2013 compared with Q3 2012. Production in Q3 2012 was partially impacted by power interruptions, which limited the Company’s ability to complete the planned underground development, and consequently reduced production tonnage, for the quarter. The Company had completed a 30-week optimization project designed to operate the mill at its name-plate capacity of 2,150 tonnes per day (“TPD”) in Q1 2013 and throughput averaged 2,172 TPD in Q3 2013 compared with 1,934 TPD in Q3 2012. Throughput in Q3 2013 was slightly lower than Q2 2013 mainly due to scheduled maintenance of the ball mills. The mill is currently undergoing expansion to 2,500 TPD that is expected to be completed by the end of Q1 2014.

MANAGEMENT’S DISCUSSION AND ANALYSIS
FOR THE THREE AND NINE MONTHS ENDED SEPTEMBER 30, 2013
Higher gold and silver grades during Q3 2013 were partially a result of mining high-grade pillars. These pillars are part of the ongoing San Dimas mine plan, but are not expected to contribute as meaningfully to Q4 2013 production.
Total cash costs on a gold equivalent and by-product basis in Q3 2013 were $516 and $252 per ounce, respectively, compared with $699 and $363 per ounce, respectively, in Q3 2012. Cash operating costs were $21.7 million in Q3 2013, $3.8 million or 21% higher than Q3 2012, however, this was offset by a 64% increase in gold equivalent ounces produced. Cash operating costs per tonne milled were $108 in Q3 2013, 8% higher than Q3 2012. Increases in input costs included $2.9 million higher labour and contractor costs (due mainly to annual pay rate increases and implementation of long hole mining) and $0.2 million higher maintenance costs for the mill and mine as compared to the prior period. Cash operating costs per tonne milled were approximately the same in Q3 2013 as Q2 2013 and Q1 2013.
The Company incurred all-in sustaining costs of $974 per gold ounce in Q3 2013, compared with $1,240 per gold ounce in Q3 2012. Since all-in sustaining costs are calculated on a by-product basis, they are lower for the Company in the second and third fiscal quarters, when the Company is able to sell silver at spot prices, than the first and fourth fiscal quarters. On an annual basis, after completion of the mill expansion, the Company expects that its all-in sustaining costs will be between $1,050 and $1,150 per gold ounce.
The 3.5 million ounce annual threshold under the silver purchase agreement was met in early April 2013, approximately half a month before last year. The Company sold 395,570 ounces and 999,046 ounces of silver, respectively, at market prices during the three and nine months ended September 30, 2013 (2012 - 246,229 ounces and 716,229 ounces), until the threshold was reset on August 6, 2013.

The Company earned net income of $10.1 million ($0.09 per share) for the three months ended September 30, 2013 compared with net income of $11.6 million ($0.12 per share) for the three months ended September 30, 2012. Significantly higher gold and silver production and sales were only partially offset by substantially lower realized commodity prices, with increased revenue and earnings from mine operations in the Q3 2013 compared with Q3 2012. Lower general and administrative expenses, due primarily to reduced share-based payment expense in Q3 2013 than Q3 2012, were offset by higher income tax expense in Q3 2013 primarily due to the impact of foreign exchange changes on deferred tax balances. Net income per share in Q3 2013 was also impacted by a 24% increase in the number of weighted average shares outstanding due mainly to the issue of 18 million shares in Q2 2013 to acquire Cerro.
Adjusted net income, which primarily excludes the impact of foreign exchange rate changes on deferred tax balances in both periods, was $11.0 million ($0.09 per share) for Q3 2013, compared with $2.6 million ($0.03 per share) for Q3 2012. The Company has no control over foreign exchange rates and the volatility of foreign exchange rate changes between the Mexican peso and the US dollar produces unpredictable and significant adjustments to deferred tax balances.

FOR THE THREE AND NINE MONTHS ENDED SEPTEMBER 30, 2013
Revenue
Revenue was $53.8 million for the three months ended September 30, 2013, 41% higher than the same period in 2012. Revenue from gold increased 44% to $40.5 million in Q3 2013 from $28.1 million in Q3 2012. Gold sales increased 77% to 30,261 ounces in Q3 2013 from 17,100 ounces in Q3 2012, and despite a 19% decline in the average realized gold price to $1,338 per ounce in Q3 2013 from $1,646 per ounce in Q3 2012. Gold and other commodity prices have declined steadily during 2013, with the sharpest decreases occurring during Q2 2013, mainly due to concerns over the cessation of quantitative easing in the U.S., the prospect of higher interest rates and a rising US dollar.
Revenue from silver increased 31% to $13.3 million in Q3 2013 from $10.1 million in Q3 2012. Silver sales increased 51% to 1.58 million ounces in Q3 2013 from 1.05 million ounces in Q3 2012, modestly offset by a 13% decline in the average realized silver price to $8.42 per ounce in Q3 2013 from $9.66 per ounce in Q3 2012. The Company sold 1.18 million ounces at an average price of $4.12 per ounce in Q3 2013 under the silver purchase agreement (see “ Silver purchase agreement” below ), compared with 0.8 million ounces at $4.08 per ounce in Q3 2012. In addition, the Company sold 395,570 ounces of silver at an average price of $21.18 in Q3 2013, compared with 246,229 ounces at an average price of $27.70 in Q3 2012.
Silver purchase agreement
In 2004, the owner of the San Dimas mine entered into an agreement to sell all the silver produced at the San Dimas mine for a term of 25 years to Silver Wheaton Caymans in return for an upfront payment comprising cash and shares of Silver Wheaton Corp. and a per ounce payment of the lesser of $3.90 (adjusted for annual inflation), or the market price. The Company was required to assume this agreement, with amendments, when it acquired the San Dimas mine. The amendments provided that for each of the first four years after the acquisition date, the first 3.5 million ounces per annum of silver produced by the San Dimas mine, plus 50% of the excess silver above this amount, must be sold to Silver Wheaton Caymans at the lesser of $4.04 per ounce (adjusted by 1% per year) and market prices. After four years, for the life of the mine, the first 6 million ounces per annum of silver produced by the San Dimas mine, plus 50% of the excess silver above this amount, must be sold to Silver Wheaton Caymans at the lesser of $4.20 per ounce (adjusted by 1% per year) and market prices. All silver not sold to Silver Wheaton Caymans is available to be sold by the Company at market prices.
The expected cash flows associated with the sale of the silver to Silver Wheaton Caymans at a price lower than the market price have been reflected in the fair value of the mining interests recorded upon acquisition of the San Dimas mine. The Company has presented the obligation to sell any silver production to Silver Wheaton Caymans as part of the mining interests, as the Company did not receive any of the original upfront payment which was made by Silver Wheaton to acquire its interest in the silver production of the San Dimas mine. Further, the Company does not believe that the obligation meets the definition of a liability as the obligation to sell silver to Silver Wheaton Caymans only arises upon production of the silver.

MANAGEMENT’S DISCUSSION AND ANALYSIS
FOR THE THREE AND NINE MONTHS ENDED SEPTEMBER 30, 2013
Operating expenses
Operating expenses of the San Dimas mine were $21.3 million in Q3 2013, up from $19.0 million in Q3 2012. The increase was due mainly to the higher volume of ounces sold and increased labour and contractor costs. The increased labour and contractor costs reflect year-over-year pay rate changes and the cost of long hole mining which commenced in Q3 2012. Total cash operating costs per ounce decreased to $516 and $252 in Q3 2013 on a gold equivalent and by-product basis, respectively, from $699 and $363, respectively, for Q3 2012 (see REVIEW OF OPERATIONS – San Dimas Mine above). Operating expenses in 2013 include $0.3 million (2012 – $0.4 million) of share-based payment expense related to personnel at the mine.
Depreciation and depletion expense
The depreciation and depletion expense was $9.5 million for Q3 2013 compared to $6.2 million for Q3 2012 due primarily to the increase in production and sales in Q3 2013. The San Dimas mining properties are depleted on a units-of-production basis and hence depletion increases as production increases.
General and administrative expenses
General and administrative expenses were $7.1 million for Q3 2013, compared to $9.4 million for Q3 2012, broken down as follows:

 	 	Three months ended	 	
 	 	September 30	 	
(In thousands of U.S. dollars)	 	2013	 	 	2012	 	
 	 	 	 	 	 	 	
Share-based payments	 	3,620	 	 	6,620	 	
Salaries and wages	 	1,095	 	 	1,012	 	
Rent and office costs	 	394	 	 	377	 	
Legal, accounting, consulting, and other professional fees	 	1,050	 	 	756	 	
Other general and administrative expenses	 	927	 	 	642	 	
Total	 	7,086	 	 	9,407	 	
The reduction in share-based payment expense in Q3 2013 was due to a 95% increase in the Company’s share price during Q3 2012, compared to a 19% increase during Q3 2013, which impacted the carrying value of units in the Company’s Phantom Share Unit Plan (“PSUP”). The carrying value of PSUs is marked-to-market each quarter based on the Company’s share price and the resulting adjustment is credited or charged to the statement of operations over the remaining vesting period of the PSUs. Other general and administrative expenses were higher in Q3 2013 partly due to increased spending on regulatory matters resulting from the Company’s ASX listing, as well as increased information technology and travel expenses related to higher staffing levels and increased travel to the Company’s operations and potential acquisition target.

MANAGEMENT’S DISCUSSION AND ANALYSIS
FOR THE THREE AND NINE MONTHS ENDED SEPTEMBER 30, 2013
Other expense
Other expense was $0.6 million in Q3 2013, compared with $0.3 million in Q3 2012 due mainly to increased spending on financing initiatives.
Finance expense
Finance expense was a credit of $0.1 million for Q3, 2013, compared to a charge of $0.3 million forQ3 2012. Accrued interest on the promissory note and convertible note was $0.3 million higher in Q3 2012 than Q3 2013 due to the full settlement of the convertible note in August 2012, as well as a $5 million instalment payment on the promissory note made on December 31, 2012 and a $7.8 million principal repayment on account of the excess free cash flow covenant in the promissory note in February 2013. Foreign exchange
The Company recorded a foreign exchange loss of $0.3 million in Q3 2013 compared with a foreign exchange gain of $0.1 million in Q3 2012. The Mexican peso depreciated against the US dollar in Q3 2013 and appreciated against the US dollar in Q3 2012 resulting in unrealized foreign exchange losses in Q3 2013 and gains in Q3 2012 on peso-denominated assets net of liabilities.
Income taxes
The Company recorded an income tax expense of $5.0 million in Q3 2013 compared with an income tax recovery of $7.5 million in Q3 2012. The impact of foreign exchange on deferred tax assets and liabilities decreased tax expense by $8.5 million in Q3 2012 and increased tax expense by $0.3 million in Q3 2013. These adjustments arise because the Company’s Mexican subsidiary measures its non-monetary assets and liabilities in its functional currency (the US dollar) for book purposes but it computes its taxes (and, hence, the tax base of its non-monetary assets and liabilities) in pesos and under IFRS changes in the exchange rate give rise to temporary differences that result in a recognized deferred tax liability or asset, with an offsetting charge or credit to profit or loss. Note 7 of the financial statements for the three and nine months ended September 30, 2013 provides a reconciliation between expected taxes based on the statutory rate and the actual income tax expense (recovery).

The Company earned net income of $31.6 million ($0.30 per share) for the nine months ended September 30, 2013 (“YTD 2013”) compared with $48.3 million ($0.54 per share) for the nine months ended September 30, 2012 (“YTD 2012”). Higher sales volumes were offset by lower commodity prices and higher operating expenses. The accrual of a $5.5 million liability for historical social security premiums, covering the period from the acquisition of the San Dimas mine in August 2010 to the end of 2012, also reduced earnings in YTD 2013 (see Other expense below). Net income was further impacted by higher income tax expense in YTD 2013 primarily due to the impact of foreign exchange changes on deferred tax balances. Net income per share for YTD 2013 was also negatively impacted by an 18% increase in the number of weighted average shares outstanding due mainly to the issue of 18 million shares in May 2013 to acquire Cerro.
Adjusted net income, which primarily excludes the accrual for historical social security premiums in YTD 2013 and the impact of foreign exchange rate changes on deferred tax balances in YTD 2013 and YTD 2012, was $37.1 million ($0.35 per share) for YTD 2013, compared with $36.8 million ($0.41 per share) for YTD 2012.

FOR THE THREE AND NINE MONTHS ENDED SEPTEMBER 30, 2013
Revenue
Revenue was $152.6 million for YTD 2013, 10% higher than the same period in 2012. Revenue from gold increased 9% to $116.6 million in YTD 2013 from $106.8 million in YTD 2012. Gold sales increased 24% to 80,689 ounces in YTD 2013 from 64,980 ounces in Q3 2012, however, the average realized gold price decreased 12% to $1,445 per ounce in YTD 2013 from $1,643 per ounce in YTD 2012. Revenue from silver increased 11% to $36.0 million in YTD 2013 from $32.5 million in YTD 2012. Silver sales increased 19% to 4.48 million ounces in YTD 2013 from 3.76 million ounces in YTD 2012, but the average realized silver price decreased 7% to $8.03 per ounce in YTD 2013 from $8.65 per ounce in YTD 2012. The Company reached the 3.5 million ounce threshold under the silver purchase agreement with Silver Wheaton Caymans in early April 2013, and subsequently sold 999,046 ounces of silver at an average price of $21.60. In the prior year, the threshold was met at the end of April, and the Company subsequently sold 716,229 ounces of silver at an average price of $28.03.
Operating expenses
Operating expenses of the San Dimas mine were $64.6 million for YTD 2013, compared to $56.2 million for YTD 2012. Gold equivalent and by-product cash costs were $580 and $350, respectively, for YTD 2013, compared with $624 and $307, respectively, for YTD 2012. A 19% increase in total cash operating costs was offset by a 28% increase in gold equivalent ounces in 2013, resulting in a 7% decrease in cash costs per gold equivalent ounce. Cash operating costs increased to $63.1 million in YTD 2013 from $52.9 million in YTD 2012 mainly due to $8.1 million higher labour and contractor costs and $1.4 million higher mine and mill maintenance. Labour and contractor costs were impacted by $2.8 million year-over-year pay rate and bonus changes, $2.5 million higher social security premiums (see Other expense below) and $1.4 million for the use of long hole mining, which was introduced at San Dimas in the third quarter of 2012. By-product cash costs per ounce increased by 14% in YTD 2013 due mainly to the lower silver price realized on spot sales, which constrained by-product silver credits. Operating expenses in YTD 2013 include $0.2 million (2012 – $0.8 million) of share-based payment expense related to personnel at the mine.
Depreciation and depletion expense
Depreciation and depletion expense was $25.7 million for YTD 2013 compared to $21.3 million for YTD 2012 due mainly to the increased production and sales volumes. The San Dimas mining properties are depleted on a units-of-production basis and hence depletion increases as production increases.

General and administrative expenses
General and administrative expenses were $16.8 million for YTD 2013, compared to $18.9 million for YTD 2012, broken down as follows:

 	 	Nine months ended	 	
 	 	September 30	 	
(In thousands of U.S. dollars)	 	2013	 	 	2012	 	
 	 	 	 	 	 	 	
Share-based payments	 	5,928	 	 	8,928

Rent and office costs	 	1,295	 	 	856	 	
Legal, accounting, consulting, and other professional fees	 	2,570	 	 	3,549	 	
Other general and administrative expenses	 	2,912	 	 	2,384	 	
Total	 	16,789	 	 	18,939	 	
The reduction in share-based payment expense in 2013 was due to a 12% decline in the Company’s share price in 2013, compared to a 58% increase in the Company’s share price in 2012, which impacted the carrying value of units in the Company’s Phantom Share Unit Plan (“PSUP”). The carrying value of PSUs is marked-to-market each quarter based on the Company’s share price and the resulting adjustment is credited or charged to the statement of operations over the remaining vesting period of the PSUs. The increase in salaries and wages reflects the hiring of new employees to support the Company’s growth and in particular to enhance its technical expertise. Legal, accounting, consulting and professional fees were higher in 2012 mainly due to not having an in-house legal function until the second quarter of 2012, consulting fees related to changing the method of estimating reserves and resources and fees for tax services in connection with the Company’s APA ruling. The increase in rent and office costs was due mainly to moving to a larger office location in Toronto in August 2012 and the increase in other general and administrative expenses was mainly due to higher spending on information technology and travel expenses. The staff increases and the acquisition of the Cerro del Gallo project resulted in more travel to the Company’s operations.
Other expense
Other expense was $6.7 million for YTD 2013, compared with $0.7 million for YTD 2012. The amount in 2013 includes $5.5 million in respect of social security premiums in Mexico for the period from the acquisition of the San Dimas mine in August 2010 to the end of 2012. When Primero acquired the San Dimas Mine in August 2010, a potential liability was known to exist related to the registration of employees at San Dimas under the Mexican social security system (“IMSS”). Mexico has a legal requirement that employees are registered for IMSS and that their employers pay premiums under the IMSS. The employees were not registered because government provided social security benefits were not available in the vicinity of the mine due to the remoteness of the location. Instead benefits were provided by the employer, DMSL. After the acquisition of the mine, Primero continued to provide social security benefits to its Mexican employees.
The Company was in talks with the IMSS authority for about two years before a resolution was reached in July 2013. Effective June 1, 2013 all of the Mexican employees were registered for IMSS and the Company is paying social security premiums on their behalf. In addition, on July 23, 2013, the IMSS authority notified the Company that it would be assessed $6.9 million in respect of past amounts due (including penalties and interest), dating back to August 2010. Consequently the Company accrued $6.9 million in its Q2 2013 financial statements, with $1.4 million, being the amount that relates to 2013, charged to operating expenses and $5.5 million, being the amount that relates to 2012 and earlier years, charged to other expenses in the statement of operations. The $6.9 million accrual was paid in August 2013.

FOR THE THREE AND NINE MONTHS ENDED SEPTEMBER 30, 2013
Finance expense
Finance expense was $0.9 million for YTD 2013, compared to $2.1 million for YTD 2012. Accrued interest on the promissory note and convertible note was $1.1 million higher in 2012 than 2013 due to the full settlement of the convertible note in August 2012, as well as a $5 million instalment payment on the promissory note made on December 31, 2012 and a $7.8 million principal repayment on account of the excess free cash flow provision in the promissory note in February 2013 (see “LIQUIDITY AND CAPITAL RESOURCES” below).
Foreign exchange
The Company recorded a foreign exchange loss of $1.0 million for YTD 2013 compared with a foreign exchange gain of $0.3 million for YTD 2012. The Mexican peso depreciated against the US dollar in the first nine months of 2013 and appreciated against the US dollar in the first nine months of 2012, producing unrealized foreign exchange losses and gains, respectively, in 2013 and 2012 on the conversion of peso denominated asset and liability balances.
Income taxes
The Company recorded an income tax expense of $5.4 million for YTD 2013, compared with an income tax recovery of $6.3 million for YTD 2012. The impact of foreign exchange on deferred tax assets and liabilities resulted in a deferred tax recovery of $11.7 million in YTD 2012 and a deferred tax expense of $0.5 million in YTD 2013. These adjustments arise because the Company’s Mexican subsidiary measures its non-monetary assets and liabilities in its functional currency (the US dollar) for book purposes but it computes its taxes (and, hence, the tax base of its non-monetary assets and liabilities) in pesos and under IFRS changes in the exchange rate give rise to temporary differences that result in a recognized deferred tax liability or asset, with an offsetting charge or credit to profit or loss. Note 7 of the financial statements for the three and nine months ended September 30, 2013 provides a reconciliation between expected taxes based on the statutory rate and the actual income tax expense (recovery).

Gold production in Q3 2013 was a record for the Company due to achieving the highest grade since the Company has owned the San Dimas mine and higher throughput attributed in part to the Company’s optimization project, which was completed at the end of Q1 2013. Gold production, and accordingly sales, were lower in Q3 2012 than Q1, Q2 and Q4 2012 partly as expected, given the sequencing of the mine plan and also because of power interruptions, which impacted the Company’s ability to complete the planned underground development and, as a result, production tonnage, for the quarter. Revenue in Q3 2013, Q2 2013, Q3 2012, Q2 2012 and Q3 2011 included $8.4 million, $13.2 million, $6.8 million, $13.3 million and $9.8 million, respectively, of silver sales at spot prices, after the Company reached the annual threshold for deliveries under the silver purchase agreement. These silver spot sales also reduced cash costs and particularly by-product cash costs, in the second and third quarters of each year.

MANAGEMENT’S DISCUSSION AND ANALYSIS
FOR THE THREE AND NINE MONTHS ENDED SEPTEMBER 30, 2013
Quarterly net income fluctuates in part as a result of items which are adjusted out in the calculation of adjusted net income, for example the impact of foreign exchange rate changes on deferred tax assets and liabilities. The reduction in adjusted net income in Q4 2012 and Q3 2012 compared with the other quarters was due mainly to lower sales volumes as described above and higher stock-based compensation, resulting from the increase in the value of issued phantom share units as a result of the increase in the price of the Company’s common shares..
The cash balance of $125.7 million at the end of Q3 2013 reflects the payout of $7.1 million of PSUs and $6.9 million of historical social security premiums, as well as above average capital expenditures at San Dimas in the quarter. Cash in Q1 2012 reflects the repayment of the first $5 million instalment of the promissory note plus $4.4 million in accrued interest thereon (see “ Debt” below under “LIQUIDITY AND CAPITAL RESOURCES”), cash in Q4 2012 also reflects the second $5 million repayment installment of the promissory note and interest paid of $2.8 million, and cash in Q1 2013 reflects a $7.8 million excess free cash flow payment against the principal of the promissory note. Cash in Q4 2011 was reduced by the $30 million convertible note repayment.
The significant increase in equity (and total assets) in Q2 2013 was due mainly to the issue of 18 million of the Company’s common shares to acquire Cerro.

NON-GAAP MEASURES
The Company has included certain non-GAAP performance measures throughout this document. These performance measures are employed by management to assess the Company’s operating and financial performance and to assist in business decision-making. The Company believes that, in addition to conventional measures prepared in accordance with GAAP, certain investors and other stakeholders also use this information to evaluate the Company’s operating and financial performance; however, these non-GAAP performance measures do not have any standardized meaning. Accordingly, these performance measures are intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP.
Non – GAAP measure – Cash costs per gold ounce
The Company has included the non-GAAP performance measures of total cash costs per gold ounce on a gold equivalent ounce and by-product basis, throughout this document. The Company reports total cash costs on a production basis. In the gold mining industry, this is a common performance measure but does not have any standardized meaning. In presenting cash costs on a production basis, the Company follows the recommendations of the Gold Institute Production Cost Standard. The Gold Institute, which ceased operations in 2002, was a non-regulatory body that represented a global group of suppliers of gold and gold products. The production cost standard developed by the Gold Institute remains the generally accepted standard of reporting cash costs of production by gold mining companies. The Company believes that, in addition to conventional measures prepared in accordance with GAAP, certain investors use this information to evaluate the Company’s performance and ability to generate cash flow. Accordingly, it is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. The Company’s primary business is gold production and maximizing returns from gold production, with other metal production being incidental to the gold production process. As a result, the Company's non-GAAP performance measures are disclosed on a per gold ounce or per gold equivalent ounce basis. The following table provides a reconciliation of total cash costs per ounce to operating expenses (the nearest GAAP measure) per the consolidated financial statements.

Gold equivalent ounces of silver produced are computed as silver ounces produced multiplied by the ratio of the average realized silver price to the average realized gold price during each quarter. For the year-to-date periods, the computation is the aggregation of each quarter’s gold equivalent ounces of silver included in the year-to-date period. The computations are shown below.

The Company produces one by-product metal, being silver. By-product silver credits are computed as silver ounces produced multiplied by the average realized silver price during a quarter. Cash costs without adjusting for by-product credits would be computed on a co-product basis, whereby total cash operating costs would be allocated separately to production of gold and silver. The basis for the allocation of costs is typically relative realized sales prices, which results in co-product cash costs being exactly the same as cash costs on a gold equivalent ounce basis. Hence cash costs without adjusting for by-product credits are equal to cash costs per gold equivalent ounce.
The Company sells the majority of its silver production at a fixed price of approximately $4 per ounce pursuant to a silver purchase agreement that the Company assumed when it acquired the San Dimas mine.

PRIMERO MINING CORP.
MANAGEMENT’S DISCUSSION AND ANALYSIS
FOR THE THREE AND NINE MONTHS ENDED SEPTEMBER 30, 2013
The fixed price approximated the cost of producing silver at the time the silver purchase agreement was entered into by the previous mine owner. The fixed price is reflected in the calculation of by-product silver credits.
Management uses total cash costs per gold equivalent ounce and by-product cash costs per gold ounce to monitor the operating performance of its mines and to assess the attractiveness of potential acquisition targets. Management also believes these measures provide investors and analysts with useful information about the Company’s underlying cash costs of operations and the impact of by-product credits on the Company’s cost structure and is a relevant metric used to understand the Company’s operating profitability and ability to generate cash flow. When deriving the production costs associated with an ounce of gold, the Company includes by-product credits as the Company considers that the cost to produce the gold is reduced as a result of the by-product sales supplementary to the gold production process, thereby allowing management and the Company’s other stakeholders to assess the net costs of gold production.

Non – GAAP measure – All-in sustaining costs per gold ounce
In June 2013, the World Gold Council (“WGC”) published a guidance note on non-GAAP metrics available to companies in the gold industry to use to report their costs in an effort to encourage improved understanding of the total costs associated with mining an ounce of gold. The WGC is a market development organization for the gold industry and is an association whose membership comprises leading gold mining companies, including Primero. The WGC is not a regulatory industry organization. The WGC worked with its member companies to develop the definition “all-in sustaining costs per gold ounce”, which it believes to be helpful to investors, governments, local communities and other stakeholders in understanding the economics of gold mining.
The Company has adopted the reporting of “all-in sustaining costs per gold ounce”. This metric is a non-GAAP performance measure and has no standardized meaning throughout the industry. Accordingly, it is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. The Company reports this measure on a gold ounces produced basis.
The Company presents all-in sustaining costs because it believes that it more fully defines the total current cost associated with producing gold. The Company also believes that this measure allows investors and other stakeholders of the Company to better understand its costs of producing gold and better assess the Company’s ability to generate cash flow from current operations. Management also uses all-in sustaining costs in evaluating the efficiency of its operations because it believes that IFRS measures, such as operating expenses, do not capture all of the costs incurred to discover, develop, and sustain gold production. As the measure seeks to reflect the full cost of gold production from current operations, it does not include capital expenditures attributable to development projects or mine expansions, exploration and evaluation costs attributable to growth projects, income tax payments and financing costs. In addition, the calculation of all-in sustaining costs does not include depreciation and depletion expense as it does not reflect the impact of expenditures incurred in prior periods. Even though, this measure is not representative of all of the Company’s cash expenditures management believes that it is a useful measure in allowing it to analyze the efficiency of its current gold mining operations.

Adjustments
All-in sustaining costs adjust “cash costs, net of by-product credits”, for corporate general and administrative expenses, reclamation cost accretion and sustaining capital expenditures. Corporate general and administrative expenses are included as a line item on the Company’s statement of operations. Sustaining capital expenditures and reclamation cost accretion are not line items on the Company’s financial statements.
Sustaining capital expenditures are defined as those capital expenditures which do not increase annual gold ounce production at a mine site and excludes all expenditures at the Company’s projects and certain expenditures at the Company’s operating sites which are deemed expansionary in nature. The following table reconciles sustaining capital expenditures to the Company’s total capital expenditures, which are disclosed in the consolidated statements of cash flows:

The Company’s exploration program comprises delineation drilling, exploration drilling, exploration drifting and regional exploration. The costs related to delineation drilling, exploration drilling and exploration drifting are included in all-in sustaining costs. The regional exploration program is designed to identify new mineral targets on the Company’s extensive land holdings in order to grow production rather than sustain production.
Reclamation cost accretion represents the growth in the Company’s decommissioning liability due to the passage of time. This amount does not reflect cash outflows but it is considered to be representative of the periodic costs of reclamation and remediation. The Company has prepared a discounted cash flow model of the estimated costs to remediate the San Dimas site at the end of the estimated mine life. Reclamation cost accretion was calculated based on a discount rate of 7.75% and estimated remediation costs of $28.9 million, which are generally expected to be incurred in 2035 and 2036. Reclamation cost accretion is included in finance expense in the Company’s consolidated statements of operations and comprehensive income.

Operating activities
During Q3 2013, the Company’s net cash flows provided by operating activities were $15.8 million, comprising cash flows before changes in working capital of $20.9 million, and changes in non-cash working capital of ($5.1) million. The cash flows before changes in working capital primarily comprised cash earnings from mine operations of $32.8 million, offset by cash general and administrative costs of $3.5 million, PSU payouts of $7.1 million, and income taxes paid of $0.4 million. The change in non-cash working capital of ($5.1) million mainly resulted from paying $6.5 million of trade and taxes payable and an increase in trade and other receivables of $1.7 million, partially offset by the refund of taxes receivable of $3.0 million.
During Q3 2012, the Company’s net cash flows provided by operating activities were $15.9 million, comprising cash flows before changes in working capital of $15.4 million and changes in non-cash working capital of $0.5 million. The cash flows before changes in working capital primarily comprised cash earnings from mine operations of $19.7 million, offset by cash general and administrative costs of $2.8 million and income taxes paid of $0.5 million.
Investing activities
Cash flows used in investing activities were $21.5 million in Q3 2013, compared with $7.0 million in Q3 2012. The majority of the outflows in Q3 2013 and substantially all of the outflows in Q3 2012 were for capital expenditures at the San Dimas Mine. In Q3 2013, the Company spent $6.8 million on major projects, $5.5 million on equipment and sustaining projects and $7.8 million on exploration, drifting and mine development at San Dimas and $1.3 million at Cerro del Gallo. The major projects mainly comprised $3.0 million for the mill expansion project to increase throughput to 2,500 TPD and $2.6 million to the new waste pad. The mill expansion project is expected to be completed in Q1 2014 and the mine development activity to match the expanded mill capacity will be completed in Q2 2014. Most of the cash outflows for investing activities in Q3 2012 were for exploration, drifting and mine development.

Investing activities
Cash flows used in investing activities were $50.5 million in YTD 2013, compared with $21.6 million in YTD 2012. A substantial part of the outflows in YTD 2013 and YTD 2012 were for exploration and delineation drilling and drifting and mine development ($21.5 million and $16.3 million in YTD 2013 and YTD 2012, respectively). In addition, in YTD 2013, the Company spent $6.3 million on the mill expansion project to increase throughput to 2,500 TPD, $3.4 million on the new waste pad, $1.7 million to initiate a project to expand the power capacity at its hydro-electric facility that is expected to be completed by the end of 2014 and $10.5 million on equipment and sustaining projects. In YTD 2013, the Company also used $4.4 million of cash as part of the acquisition of Cerro and investment in Santana.
Financing activities
The Company used $5.9 million of cash for financing activities in YTD 2013, comprising the $7.8 million excess free cash flow payment relating to the promissory note (see “ Debt” below), partially offset by $1.9 million of cash received upon the exercise of stock options.
The Company used $11.3 million of cash for financing activities in YTD 2012, relating to the repayment of the first $5.0 million instalment under the promissory note and $4.4 million of interest thereon, as well as $1.9 million of interest paid on the convertible note prior to conversion (see “ Debt” below).
Debt
On August 6, 2010, in connection with the acquisition of the San Dimas Mine, the Company issued a promissory note for $50 million and a convertible note for $60 million to DMSL, a subsidiary of Goldcorp. The convertible note was fully repaid in August 2012.
The promissory note bears interest at 6% per annum and is repayable in four annual installments of $5 million, starting on December 31, 2011, with the balance of principal due on December 31, 2015. On January 3, 2012, the Company repaid the first $5 million annual installment plus accrued interest of $4.4 million. The second annual installment of $5 million plus accrued interest of $2.8 million was paid on December 31, 2012. In addition to the annual installments, the Company is required to pay 50% of annual excess free cash flow (as defined in the promissory note) against the principal balance. The Company generated excess free cash flow of $15.6 million during the year ended December 31, 2012 and accordingly paid $7.8 million to the note holder in February 2013. As at September 30, 2013, the amount outstanding under the promissory note was $32.2 million.
The Company is subject to a number of externally imposed capital requirements relating to its debt. The requirements are both financial and operational in nature; the Company has complied with all such requirements during the period.
Pursuant to the terms of the promissory note the Company is required to maintain the following financial covenants:

 	•	Tangible net worth as at the end of each fiscal quarter of at least $400 million, and	
 	•	Free cash flow of at least $10 million, calculated on a rolling four fiscal quarter basis.	
Tangible net worth means equity less intangible assets. Free cash flow means cash flow from operating activities as reported in the consolidated statement of cash flows, less the aggregate of capital expenditures at the San Dimas mine, principal and interest on the promissory note, and up to $5 million per year on account of acquisition opportunities.

MANAGEMENT’S DISCUSSION AND ANALYSIS
FOR THE THREE AND NINE MONTHS ENDED SEPTEMBER 30, 2013
Liquidity outlook
As at September 30, 2013, the Company had cash of $125.7 million and working capital of $122.8 million. Management estimates that based on spot metal prices at the point of writing this MD&A, San Dimas will generate average annual after-tax operating cash flows of approximately $90 million (including the tax reform changes discussed below). The Company expects its current cash resources, as well as ongoing cash flow from the San Dimas mine, will be sufficient to fund its operations and certain potential acquisition opportunities for the foreseeable future. Nonetheless, in order to enhance its financial flexibility, the Company is in negotiations with a major financial institution to secure a revolving line of credit of $75 million, which it expects to complete in Q4 2013, and is also considering other financing initiatives.
When the Company purchased the San Dimas mine it assumed a silver purchase agreement under which the majority of silver produced at the mine was sold at a fixed price of approximately $4 per ounce. On October 4, 2012, the Company received a ruling from the Mexican tax authorities that confirmed that the Company's Mexican subsidiary appropriately records revenue and taxes from sales under the silver purchase agreement at realized prices rather than spot prices effective from August 6, 2010. This ruling significantly improves the Company’s cash flow over the five-year duration of the ruling (which expires at the end of 2014). Assuming the Company continues to sell silver from its San Dimas mine on the same terms and there are no changes in the application of Mexican tax laws relative to the ruling, the Company expects to pay taxes on realized prices for the life of the San Dimas mine.
The Company expects to spend approximately $45 million on capital expenditures at the San Dimas mine in 2013, with approximately 52% of 2013 capital expenditures allocated to projects and 48% to operations. The 2013 project capital includes the mill expansion to 2,500 TPD ($10.7 million), the first phase of a two-year waste rock pad project ($6.8 million) designed to support the long-term waste disposal at San Dimas and the initial expenditure to increase the capacity of the Company’s hydro-electric facility ($3 million). In addition, the Company expects to spend approximately $15.4 million on exploration, aimed towards increasing reserves and resources and defining higher-grade underground ore. The exploration work will be divided between district exploration (field activities and exploration drilling from surface on the San Dimas property as well as the Ventanas property) and mine exploration (delineation and exploration drilling and drifting from underground in the San Dimas mine). The mine exploration program includes approximately 89,000 metres of diamond drilling, comprising 41,000 metres of exploration drilling and 48,000 metres of delineation drilling. In addition, the Company expects to undertake 3,800 metres of exploration drifting in 2013. The district exploration program includes approximately 19,000 metres of drilling and will focus mainly on new discoveries as well as on the surface features of the known underground veins. For the nine months ended September 30, 2013, the Company had spent approximately $44 million on capital expenditures at San Dimas including exploration, leaving approximately $16 million to be spent in the last quarter of 2013.
Capital expenditures for the Cerro del Gallo project
The Company completed the acquisition of Cerro on May 22, 2013. After the spinout of Cerro’s non-Cerro del Gallo assets to Santana Minerals Limited (“Santana”) , Cerro’s only mining property was its 69.2% interest in the Cerro del Gallo project. The Company has reduced its estimated capital spending in 2013 to approximately $15 million (on a 100% ownership basis) in order to advance the project to a construction decision. This spending is expected to be sufficient to complete all outstanding permitting, land acquisition, basic engineering of the mine processing facilities and a preliminary exploration program, including condemnation drilling. The Company expects to make a construction decision before the end of 2013. Given the significant decline in the gold price in 2013 the Company is committed to advancing the project to a construction decision with a limited investment and will make a construction decision based on the market conditions and the return expected from the project at the end of the year.

PRIMERO MINING CORP.
MANAGEMENT’S DISCUSSION AND ANALYSIS
FOR THE THREE AND NINE MONTHS ENDED SEPTEMBER 30, 2013
The May 2012 Definitive Feasibility Study (“DFS”) 1 on the Cerro del Gallo project contemplated only a phase one (“Phase I”) heap leach of 4.5 million tonnes per year of oxidized and partially oxidized ore for 7.2 years of production. In March 2011, a preliminary assessment identified a potential phase two (“Phase II”) addition of carbon-in-leach (“CIL”) processing of fresh rock commencing in year 5.
Following the acquisition of the Cerro del Gallo project Primero commenced an assessment of the alternatives to the long term development of the project which include a heap leach only operation (Phase I), an accelerated timetable for the CIL processing facility (Phase II) and a CIL only operation. The key elements of the assessment will be the trade-off between capital and metal recovery as well as the impact of various processing approaches to the reserve and resource base. Further drilling is part of this assessment program and will focus on the detailed metallurgical characterization of the transition zone as well as the unoxidized mineralization at depth and lateral to ore considered in the Phase I development plan. The exploration work also being conducted concurrently will be an important component for the development decision. The Company expects to complete its assessment by the end of 2013 concurrent with its construction decision. The DFS estimated capital expenditures of $154 million (based on 100% ownership) for the Phase 1 heap leach. The Company is currently completing its own optimization and costing studies.
Primero expects to spend approximately $4 million of the budgeted $15 million in 2013 on exploration. The exploration program includes 12,000 metres of infill drilling and condemnation drilling as well as regional mapping and geochemical assessment. This is the first exploration program conducted on the Cerro del Gallo property since 2008. The infill drilling program is designed to convert inferred resources to indicated resources in the central part of the mineralized zone. The Company expects to publish an updated Reserve and Resource estimate for Cerro del Gallo in early 2014. The condemnation drilling program is designed to sterilize the area for future waste dump and leach pads.
Recent Mexican tax reform announcement
On October 31, 2013, the Mexican Congress approved an extensive tax reform bill that has far reaching implications to the mining sector and taxpayers generally. The reforms include a tax-deductible mining royalty of 7.5% on earnings before the deduction of interest, taxes, depreciation and amortization, with precious metals mining companies paying an additional 0.5% on precious metals revenue, which is a significant increase to the 5% rate proposed in April 2013. In addition, the long term corporate tax rate will remain at 30% rather than reduce to 28% as originally planned and deductions for accelerated depreciation of exploration costs and certain other capital expenditures are no longer allowed. The tax reform bill has now been sent to the President for signature and enactment. It is expected to be enacted by November 15, 2013 and be effective on January I, 2014. The new tax reforms are applicable on a prospective basis and therefore affect future earnings from the Company’s mining operations in Mexico. Mining companies may be able to undertake community development projects in lieu of the royalty. Under the proposal, in each state, a committee for the regional development of mining areas would be created, with representatives from the federal, state and municipal governments, native communities, and the mining companies operating in the State. This committee would establish infrastructure and public works projects to benefit the areas surrounding mining activity that should be carried out by each mining company. The expenses associated with these projects would be allowed as credits against the royalty.

PRIMERO MINING CORP.
MANAGEMENT’S DISCUSSION AND ANALYSIS
FOR THE THREE AND NINE MONTHS ENDED SEPTEMBER 30, 2013
The impact of the tax reforms on the Company is significant and is estimated to be approximately $14 million in 2014. Everything else being equal, the impact reduces somewhat in later years due to higher deductions for depreciation and exploration costs resulting from the elimination of accelerated deductions for these items.
Related party transactions
At September 30, 2013, Goldcorp owned approximately 27% of the Company’s common shares. The Company has a promissory note outstanding to a wholly-owned subsidiary of Goldcorp.

ADOPTION OF NEW ACCOUNTING STANDARDS
Changes in accounting policies and future accounting pronouncements
The Company has adopted the following new and revised standards, along with any consequential amendments, effective January 1, 2013. These changes were made in accordance with the applicable transitional provisions.
In June 2011, the IASB issued amendments to IAS 1 – Presentation of Financial Statements (“IAS 1”). The amendments are effective for annual periods beginning on or after July 1, 2012. The amendments to IAS 1 require companies preparing financial statements in accordance with IFRS to group together items within OCI that may be reclassified to the profit or loss section of the Consolidated Statement of Operations from those that will not be reclassified. The amendments also reaffirm existing requirements that items in OCI and profit or loss should be presented as either a single statement or two consecutive statements.
The Company applied the amendments to IAS 1 effective January 1, 2013 and accordingly has grouped OCI items as required for both the current and comparative period.
In May 2011, the IASB issued IFRS 10 - Consolidated Financial Statements (“IFRS 10”), which supersedes SIC 12 - Consolidation- Special Purpose Entities and the requirements relating to consolidated financial statements in IAS 27 - Consolidated and Separate Financial Statements. IFRS 10 establishes control as the basis for an investor to consolidate its investees and defines control as an investor’s power over an investee with exposure, or rights.
33

PRIMERO MINING CORP.
MANAGEMENT’S DISCUSSION AND ANALYSIS
FOR THE THREE AND NINE MONTHS ENDED SEPTEMBER 30, 2013
The Company adopted IFRS 10 on January 1, 2013 on a retrospective basis; there has been no impact upon the Company’s financial statements as a result of the adoption.
IFRS 11, Joint Arrangements, supersedes IAS 31, Interests in Joint Ventures, and requires joint arrangements to be classified either as joint operations or joint ventures depending on the contractual rights and obligations of each investor that jointly controls the arrangement. For joint operations, a company recognizes its share of assets, liabilities, revenues and expenses of the joint operation. An investment in a joint venture is accounted for using the equity method as set out in IAS 28, Investments in Associates and Joint Ventures (amended in 2011).
The Company adopted IFRS 11 on January 1, 2013 on a retrospective basis. There was no impact on the Company’s financial statements in the prior period. The Company accounts for its investment in the entity which owns the Cerro del Gallo project as a joint operation.
IFRS 13 Fair Value Measurement (“IFRS 13”) was issued by the IASB in May 2011, and is effective for annual periods beginning on or after January 1, 2013. IFRS 13 was issued to remedy the inconsistencies in the requirements for measuring fair value and for disclosing information about fair value measurement in various current IFRSs. IFRS 13 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. IFRS 13 relates to how to measure fair value, not what should be measured at fair value. The Company adopted IFRS 13 on January 1, 2013 on a prospective basis. The adoption of IFRS 13 did not require any adjustments to the valuation techniques used by the Company to measure fair value and did not result in any measurement adjustments as at January 1, 2013.
In October 2011, the IASB issued IFRIC 20 - Stripping Costs in the Production Phase of a Mine (“IFRIC 20”). IFRIC 20 clarifies the requirements for accounting for the costs of stripping activities in the production phase of an open-pit mine when two benefits accrue: (i) usable ore that can be used to produce inventory and (ii) improved access to further quantities of material that will be mined in future periods. The IFRIC allows a company to determine a measure to allocate costs between inventory produced and the stripping activity asset; the IFRIC provides examples of measures.
IFRIC 20 is effective for annual periods beginning on or after January 1, 2013. With the acquisition of Cerro on May 22, 2013, the Company acquired a 69.2% interest in the Cerro del Gallo project, which is planned to be an open pit mine. The Company will apply the provisions of IFRIC 20 to the Cerro del Gallo project and develop a policy for allocation of costs once stripping activity begins.
CRITICAL ACCOUNTING ESTIMATES AND JUDGEMENTS
The preparation of financial statements in conformity with IFRS requires management to make estimates, judgements and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Management has identified the following critical accounting policies and estimates.
34

PRIMERO MINING CORP.
MANAGEMENT’S DISCUSSION AND ANALYSIS
FOR THE THREE AND NINE MONTHS ENDED SEPTEMBER 30, 2013
Inventories
Finished goods, work-in-process and stockpiled ore are valued at the lower of average production cost and net realizable value.
The Company records the costs of mining ore in process as work-in-process inventories measured at the lower of cost and estimated net realizable value. These costs are charged to income and included in operating expenses on the basis of ounces of gold recovered. The estimates and assumptions used in the measurement of work-in-process inventories include quantities of recoverable ounces of gold and silver in the mill processing circuits and the price per gold ounce expected to be realized when the ounces of gold are recovered. If these estimates or assumptions prove to be inaccurate, the Company could be required to write down the carrying amounts of its work-in-process inventories, which would reduce the Company’s income and working capital. At September 30, 2013, the average costs of inventories are significantly below their net realizable values.
Mining interests and impairment testing
The Company records mining interests at cost. Exploration costs are capitalized where they meet the Company’s criteria for capitalization.
A significant portion of the Company’s mining properties are depleted using the units-of-production method. Under the units-of-production method, depletion of mining properties is based on the amount of reserves and the portion of mineralization expected to be recovered from the mines. If estimates of reserves and mineralization expected to be recovered prove to be inaccurate, or if the Company revises its mining plan for a location, due to reductions in the metal price forecasts or otherwise, to reduce the amount of reserves and mineralization expected to be recovered, the Company could be required to write down the carrying amounts of its mining properties, or to increase the amount of future depletion expense, both of which would reduce the Company’s income and net assets.
The Company reviews and evaluates its mining properties for impairment when events or changes in circumstances indicate that the related carrying amounts may not be recoverable. For the three months and nine months ended September 30, 2013, no events or changes in circumstances were identified which would indicate an impairment and as such no impairment review was performed. If the Company determines there has been an impairment because its prior estimates of future net cash flows have proven to be inaccurate, due to reductions in the metal price forecasts, increases in the costs of production, reductions in the amount of reserves expected to be recovered or otherwise, or because the Company has determined that the deferred costs may not be recovered based on current economics or permitting considerations, the Company would be required to write down the carrying amounts of its mining properties, which would reduce the Company’s earnings and net assets.
Plant and equipment are depreciated over their estimated useful lives. If estimates of useful lives including the economic lives of mines prove to be inaccurate, the Company could be required to write down the carrying amounts of its plant and equipment, or increase the amount of future depreciation expense, both of which would reduce the Company’s income and net assets.
Fair value of assets purchased in a business combination
The Company’s business combinations are accounted for using the acquisition method of accounting whereby assets acquired and liabilities assumed are recorded at their fair values as of the date of acquisition and any excess of the purchase price over such fair values is recorded as goodwill. No goodwill has been recorded to date.
35

PRIMERO MINING CORP.
MANAGEMENT’S DISCUSSION AND ANALYSIS
FOR THE THREE AND NINE MONTHS ENDED SEPTEMBER 30, 2013
Assumptions underlying fair value estimates are subject to significant risks and uncertainties, which if incorrect could lead to an overstatement of the mineral properties of the Company which would then be subject to an impairment test as described above.
Reclamation and closure cost obligations
The Company has an obligation to reclaim its mining properties after the minerals have been mined from the site, and has estimated the costs necessary to comply with existing reclamation standards. IFRS requires the Company to recognize the fair value of a decommissioning liability, such as site closure and reclamation costs, in the period in which it is incurred if a reasonable estimate of fair value can be made. The Company records the estimated present value of future cash flows associated with site closure and reclamation as liabilities when the liabilities are incurred and increases the carrying values of the related assets by the same amount. At the end of each reporting period, the liabilities are increased to reflect the passage of time (accretion expense). Adjustments to the liabilities are also made for changes in the estimated future cash outflows underlying the initial fair value measurements, and changes to the discount rate used to present value the cash flows, both of which may result in a corresponding change to the carrying values of the related assets. The capitalized asset retirement costs are amortized to income over the life of the related assets using the units-of-production method. Should the estimation of the reclamation and closure cost obligations be incorrect, additional amounts may need to be provided for in future which could lead to an increase in both the liability and associated asset. Should the reported asset and liability increase, the amortization expense in the statement of operations of the capitalized asset retirement cost would increase.
Taxation
The Company recognizes the future tax benefit related to deferred income tax assets to the extent that it is probable that future taxable profits will be available against which they can be utilized. Assessing the recoverability of deferred income tax assets requires management to make significant estimates related to expectations of future taxable income, applicable tax strategies and the expected timing of the reversals of existing temporary differences. In making its assessments, management gives additional weight to positive and negative evidence that can be objectively verified. Estimates of future taxable income are based on forecasted cash flows from operations and the application of existing tax laws in each jurisdiction. Forecasted cash flows from operations are based on life of mine projections internally developed and reviewed by management.
The Company recognizes current income tax benefits when it is more likely than not, based on technical merits, that the relevant tax position will be sustained upon examination by applicable tax authorities. The more likely than not criteria is a matter of judgment based on the individual facts and circumstances of the relevant tax position evaluated in light of all available evidence.
The recoverability of deferred income tax assets and the recognition and measurement of uncertain tax positions are subject to various assumptions and management judgment. Actual results may differ from these estimates. In circumstances where the applicable tax laws and regulations are either unclear or subject to ongoing varying interpretations, it is reasonably possible that changes in these estimates could occur that materially affect the amounts of current and deferred income taxes recognized by the Company, as well as deferred income tax assets and liabilities recorded at September 30, 2013.

Share-based payments
For equity-settled stock option awards, the fair value of the award is charged to the statement of operations and credited to the share-based payment reserve rateably over the vesting period, after adjusting for the number of awards that are expected to vest. The fair value of the awards is determined at the date of grant using the Black-Scholes option pricing model. To the extent that the inputs into the Black-Scholes pricing model are inaccurate, there could be an increase or decrease to the share-based payment charge to the statement of operations.
Capital management
There have been no significant changes in the Company’s objectives, policies and processes for managing its capital, including items the Company regards as capital, during the three and nine months ended September 30, 2013. At September 30, 2013, the Company expects its capital resources and projected cash flows from continuing operations to support its normal operating requirements on an ongoing basis, planned development and exploration of its mineral properties, and other expansionary plans. At September 30, 2013, there were no externally imposed capital requirements to which the Company is subject and with which the Company had not complied.
Financial instruments
The Company’s financial instruments at September 30, 2013 consist of cash, trade and other receivables, trade and other payables, and debt.
At September 30, 2013 the carrying amounts of cash, trade and other receivables, trade and other payables are considered to be reasonable approximation of their fair values due to their short-term nature.
The fair value of the promissory note upon initial recognition was considered to be its face value and the promissory note has subsequently been carried at amortized cost. At September 30, 2013, the fair value of the promissory note was $33.9 million using a discounted future cash-flow analysis.
RISKS AND UNCERTAINTIES
Financial instrument risk exposure
The following describes the types of financial instrument risks to which the Company is exposed and its objectives and policies for managing those risk exposures:
(a)        Credit risk
Credit risk is the risk that the counterparty to a financial instrument will cause a financial loss for the Company by failing to discharge its obligations. Credit risk is primarily associated with trade and other receivables; however, it also arises on cash. To mitigate exposure to credit risk on financial assets, the Company limits the concentration of credit risk, ensures non-related counterparties demonstrate minimum acceptable credit worthiness and ensures liquidity of available funds.
The Company closely monitors its financial assets, invests its cash in highly rated financial institutions and sells its products exclusively to organizations with strong credit ratings. The credit risk associated with trade receivables at September 30, 2013 is considered to be negligible.
37

PRIMERO MINING CORP.
MANAGEMENT’S DISCUSSION AND ANALYSIS
FOR THE THREE AND NINE MONTHS ENDED SEPTEMBER 30, 2013
The Company’s maximum exposure to credit risk at September 30, 2013 and December 31, 2012 was as follows:

 	 	September 30, 2013	 	 	December 31, 2012	 	
 	 	 	 	 	$ 	 	
 	 	 	 	 	 	 	
Cash	 	125,709	 	 	139,244	 	
Trade and other receivables	 	5,875	 	 	3,792	 	
Taxes receivable	 	9,168	 	 	5,914	 	
(b)      Liquidity risk
Liquidity risk is the risk that the Company will encounter difficulty in meeting obligations associated with its financial liabilities that are settled by delivering cash or another financial asset. The Company has developed a planning, budgeting and forecasting process to help determine the funds required to support its normal operating requirements on an ongoing basis and its expansionary plans.
In the normal course of business, the Company enters into contracts and performs business activities that give rise to commitments for future minimum payments. The following table summarizes the contractual maturities of the Company’s financial liabilities and operating and capital commitments at September 30, 2013:

 	 	 	 	 	 	 	 	 	 	 	 	 	 	December 31

 	 	52,021	 	 	36,857	 	 	33,972	 	 	122,850	 	 	129,368	 	
The Company expects to discharge its commitments as they come due from its existing cash balances, cash flow from operations and collection of receivables.
The total operating lease expense during the three and nine months ended September 30, 2013 was $0.2 million and $0.6 million, respectively (2012 - $0.1 million and $0.4 million, respectively).

(c)	Market risk	
 	 	 	
	(i)	Currency risk	
 	 	 	
		Currency risk is the risk that the fair values or future cash flows of the Company’s financial instruments will fluctuate because of changes in foreign currency exchange rates. Exchange rate fluctuations may affect the costs incurred in the operations. Gold is sold in U.S. dollars and costs are incurred principally in U.S. dollars and Mexican pesos. The Company also holds cash that is denominated in Canadian dollars and Mexican pesos which are subject to currency risk.	
 	 	 	
		During the three and nine months ended September 30, 2013, the Company recognized a loss of $0.3 million and $1.0 million, respectively, on foreign exchange (2012 - gain of $0.1 million and $0.3 million, respectively).	
 	 	 	
		The Company does not currently use derivative instruments to reduce its exposure to currency risk, however, management monitors its differing currency needs and tries to reduce its exposure to currency risks through exchanging currencies at what are considered to be optimal times.	
 	 	 	
	(ii)	Interest rate risk	
 	 	 	
		Interest rate risk is the risk that the fair values and future cash flows of the financial instruments will fluctuate because of changes in market interest rates. The exposure to interest rates is monitored. The Company has very limited interest rate risk as the net exposure of financial instruments subject to floating interest rates is not material.	
 	 	 	
	(iii)	Price risk	
 	 	 	
		Price risk is the risk that the fair value or future cash flows of the Company’s financial instruments will fluctuate because of changes in commodity prices. Profitability depends on sales prices for gold and silver. Metal prices are affected by numerous factors such as the sale or purchase of gold and silver by various central banks and financial institutions, interest rates, exchange rates, inflation or deflation, fluctuations in the value of the U.S. dollar and foreign currencies, global and regional supply and demand, and the political and economic conditions of major producing countries throughout the world.	
Other risks and uncertainties
In 2013, there have been no changes to the Company’s exposure to other risks and uncertainties, including risks relating to the Company’s foreign operations, government regulation, and environmental regulation, as described in the 2012 year-end MD&A or the Company’s Annual Information Form for the year ended December 31, 2012, which are available on the Company’s website www.primeromining.com and on the Company’s profile at www.sedar.com.
Disclosure controls and procedures
Disclosure controls and procedures form a framework designed to provide reasonable assurance that information disclosed publicly fairly presents in all material respects the financial condition, results of operations, and cash flows of the Company for the periods presented in this MD&A. The Company’s disclosure controls and procedures framework includes processes designed to ensure that material information relating to the Company, including its consolidated subsidiaries, is made known to management by others within those entities to allow timely decisions regarding required disclosure.
39

PRIMERO MINING CORP.
MANAGEMENT’S DISCUSSION AND ANALYSIS
FOR THE THREE AND NINE MONTHS ENDED SEPTEMBER 30, 2013
The Company’s management, with the participation of its CEO and CFO, has evaluated the design, operation and effectiveness of the Company’s disclosure controls and procedures. Based on the results of that evaluation, the Company’s CEO and CFO have concluded that, as of the end of the period covered by this report, the Company’s disclosure controls and procedures were effective to provide reasonable assurance that the information required to be disclosed by the Company in its annual filings, interim filings or other reports filed or submitted by it under securities legislation is recorded, processed, summarized and reported, within the time periods specified in the securities legislation, and is accumulated and communicated to the Company’s management, including the CEO and CFO, as appropriate to allow timely decisions regarding required disclosure.
Internal controls over financial reporting
The Company’s management, with the participation of its CEO and CFO, is responsible for establishing and maintaining adequate internal control over financial reporting. The Company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with IFRS. The Company’s internal control over financial reporting includes policies and procedures that:
·	pertain to the maintenance of records that accurately and fairly reflect, in reasonable detail, the transactions and dispositions of assets of the Company;
·	provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with IFRS and that the Company’s receipts and expenditures are made only in accordance with authorizations of management and the Company’s Directors; and
·	provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Company’s assets that could have a material effect on the Company’s consolidated financial statements.
There has been no material change in internal controls of the Company during the three and nine months ended September 30, 2013 that has materially affected, or is likely to materially affect, the Company’s internal control over financial reporting.
Readers are cautioned that any controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Due to the inherent limitations in all controls systems, they cannot provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been prevented or detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by unauthorized override of the control. The design of any control system also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Accordingly, because of the inherent limitations in a cost effective control system, misstatements due to error or fraud may occur and not be detected.

MANAGEMENT’S DISCUSSION AND ANALYSIS
FOR THE THREE AND NINE MONTHS ENDED SEPTEMBER 30, 2013
No assurance can be given as to whether these assumptions will prove to be correct. These assumptions should be considered carefully by investors. Investors are cautioned not to place undue reliance on the forward-looking information and statements or the assumptions on which the Company’s forward-looking information and statements are based.
Forward-looking information is subject to a variety of risks and uncertainties which could cause actual events or results to differ from those reflected in the forward-looking statements. Such risks include, but are not limited to: the volatility of prices of gold and other metals; uncertainty of mineral reserves, mineral resources, exploration potential, mineral grades and mineral recovery estimates; uncertainty of future production, delays in completion of the mill expansion at San Dimas, exploration and development plans; insufficient capital to complete mill expansion at San Dimas, development and exploration plans; risks associated with developing the Cerro del Gallo project; currency fluctuations; financing of additional capital requirements; cost of exploration and development programs; inability to complete the Sinaloa Graben/Central Block tunnel or other development; mining risks, including unexpected formations and cave-ins, which delay operations or prevent extraction of material; risks associated with foreign operations; governmental and environmental regulation; tax law changes; the ability of the Company to continue to pay taxes based on the realized price of silver; the volatility of the Company's stock price; landowner dissatisfaction and disputes; delays in permitting; damage to equipment; labour disruptions; interruptions. Should one or more of these risks and uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those described in forward-looking statements.
Investors are advised to carefully review and consider the risk factors identified in this MD&A under the heading “ Risk and uncertainties ”, and in the Company’s Annual Information Form for the year ended December 31, 2012 as filed on SEDAR for a discussion of the factors that could cause the Company’s actual results, performance and achievements to be materially different from any anticipated future results, performance or achievements expressed or implied by the forward-looking statements. Investors are further cautioned that the foregoing list of assumptions and risk factors is not exhaustive and it is recommended that prospective investors consult the more complete discussion of the Company’s business, financial condition and prospects that is included in this MD&A. The forward-looking information and statements contained in this MD&A are made as of the date hereof and, accordingly, are subject to change after such date.
42

PRIMERO MINING CORP.
MANAGEMENT’S DISCUSSION AND ANALYSIS
FOR THE THREE AND NINE MONTHS ENDED SEPTEMBER 30, 2013
The Company does not undertake to update any forward-looking information, except as, and to the extent, required by applicable securities laws. The forward-looking statements contained herein are expressly qualified by this cautionary statement.
Cautionary Note for United States Investors
As a British Columbia corporation and a “reporting issuer” under Canadian securities laws, the Company is subject to certain rules and regulations issued by Canadian Securities Administrators. The Company is required to provide detailed information regarding its properties including mineralization, drilling, sampling and analysis, on security of samples and mineral reserve estimates under Canadian National Instrument 43-101 (“NI 43-101”). The United States Securities and Exchange Commission applies different standards than the standards under NI 43-101 in order to classify mineralization as a reserve. Accordingly, mineral reserve estimates contained in this MD&A may not qualify as “reserves” under SEC standards. Further, the Company describes any mineral resources associated with its properties utilizing terminology such as “measured resources”, “indicated resources” or “inferred resources” which are terms recognized by Canadian regulators under NI 43-101 but not recognized by the United States’ Securities and Exchange Commission. United States investors are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted into mineral reserves. These terms have a greater amount of uncertainty as to their existence and feasibility than reserves recognized by the United States Securities and Exchange Commission. Further, “inferred resources” have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically. Therefore, United States investors are also cautioned not to assume that all or any part of the “inferred resources” exist. United States investors are also cautioned that disclosure of exploration potential is conceptual in nature by definition and there is no assurance that exploration of the mineral potential identified will result in any category of NI 43-101 mineral resources being identified.

(Amounts in tables in thousands of United States dollars unless otherwise stated)

1.	Nature of operations	
 	 	
	Primero Mining Corp. (“Primero” or the “Company”) was incorporated in Canada on November 26, 2007 under the Business Corporations Act (British Columbia). The Company’s registered office is Suite 1500, 1055 West Georgia Street, Vancouver, British Columbia. Primero is a publicly traded company, listed on the Toronto, New York and Australian Stock Exchanges; Primero has no parent company (Note 19).	
 	 	
	Primero is a Canadian-based precious metals producer with mining operations in Mexico. The Company is focused on building a portfolio of high-quality, low-cost precious metals assets in the Americas through acquiring, exploring, developing and operating mineral resource properties.	
 	 	
	The Company owns one producing property, the San Dimas gold-silver mine, mill and related assets (the “San Dimas Mine”), located in Mexico’s San Dimas district, on the border of Durango and Sinaloa states, a 69.2% interest (Note 19) in one project in the development stage, Cerro del Gallo, located in the state of Guanajuato in central Mexico and one exploration property, Ventanas, located in Durango state, Mexico. Primero currently has two reportable operating segments: the San Dimas Mine (which currently includes the Ventanas property) and the Cerro del Gallo project.	
 	 	
2.	Acquisition of Cerro Resources NL	
 	 	
	On May 22, 2013, the Company acquired all of the issued and outstanding common shares of Cerro Resources NL (“Cerro”) by way of a scheme of arrangement (the "Arrangement") under the Australian Corporations Act 2001. Cerro was an exploration and development company whose principal asset was 69.2% ownership of the feasibility stage Cerro Del Gallo project, a gold-silver-copper deposit located in the state of Guanajuato, Mexico.	
 	 	
	Under the terms of the Arrangement, each Cerro shareholder received 0.023 of a Primero common share for each Cerro common share held, and each Cerro option holder received 0.023 of a Primero option for each Cerro option held. Additionally, Cerro shareholders received 80.01% of the common shares of a newly incorporated company, Santana Minerals Limited ("Santana"). Santana assumed Cerro's interests in the Namiquipa, Espiritu Santo, Mt Philp and Kalman projects, shares in Syndicated Metals Limited and approximately $4 million in cash. The Company subscribed for a 19.99% interest in Santana, which is held by the Company as an equity accounted investment. It has been determined significant influence exists due to Primero’s 25% representation on the Santana Board of Directors. As such, the Company records its share of Santana’s quarterly profit or loss, and adjusts the carrying value of the investment accordingly. There are currently no transactions between the Company and Santana. The initial value assigned to the Company’s interest in Santana was based on 19.99% of Santana’s total market capitalization.	
 	 	
	After the spinout of Santana, Cerro’s only asset was its interest in the Cerro del Gallo project. The Company determined that the Cerro del Gallo project was not a business and therefore it accounted for the acquisition as an asset acquisition rather than a business combination. The following table summarizes the fair value of the consideration transferred to Cerro shareholders, including transaction costs, and the amounts of identified assets acquired and liabilities assumed:

3.	Significant accounting policies	
 	 	
	These condensed consolidated interim financial statements have been prepared in accordance with International Accounting Standard (“IAS”) 34, “ Interim Financial Reporting ”, as issued by the International Accounting Standards Board (“IASB”) and using the accounting policies the Company expects to adopt in its consolidated financial statements for the year ending December 31, 2013 based on current standards. The accounting policies followed in these condensed consolidated interim financial statements are the same as those applied in the Company’s consolidated financial statements for the year ended December 31, 2012, except for new accounting policies described in Note 4.	
 	 	
	These condensed consolidated interim financial statements do not include all the necessary annual disclosures in accordance with IFRS. These condensed consolidated interim financial statements should be read in conjunction with the Company’s consolidated annual financial statements for the year ended December 31, 2012.	
 	 	
	These condensed consolidated interim financial statements have been prepared on a historical cost basis.	
 	 	
	These condensed consolidated interim financial statements were approved by the Company’s Board of Directors on November 5, 2013.	
 	 	
	The preparation of the condensed consolidated interim financial statements requires management to make estimates, judgements and assumptions that affect the reported amounts of revenues, expenses, assets, and liabilities at the date of the condensed consolidated interim financial statements. If in future such estimates, judgments and assumptions, which are based on management’s best judgment at the date of the condensed consolidated interim financial statements, deviate from actual circumstances, the original estimates, judgments and assumptions will be modified as appropriate in the period in which the circumstances change.	
 	 	
	In the opinion of management, all adjustments necessary to present fairly the financial position of the Company as at September 30, 2013 and the results of its operations and cash flows for the three and nine months then ended have been made. The interim results are not necessarily indicative of results for a full year.

SEPTEMBER 30 2013	
(Amounts in tables in thousands of United States dollars unless otherwise stated)	
(Unaudited)	

 	(a)	Basis of consolidation	
 	 	 	
 		These condensed consolidated financial statements include the accounts of the Company and its subsidiaries from their respective dates of acquisition. All intragroup assets and liabilities, equity, income, expenses and cash flows relating to transactions between entities of the group have been eliminated in full. The Company’s significant subsidiaries, which are wholly owned are: Primero Empresa Minera, S.A. de C.V., which owns the San Dimas Mine, Cerro Resources NL (“Cerro”), Silver Trading (Barbados) Limited (“Silver Trading”) and Primero Mining Luxembourg S.a.r.l. The Company also owns 69.2% of the entity which owns the Cerro de Gallo project.	
 	 	 	
 	(b)	Functional and presentation currency	
 	 	 	
 		The functional currency of Primero Empresa Minera, S.A. de C.V, Silver Trading, and certain subsidiaries of Cerro is the U.S. dollar. The functional currency of the other subsidiaries of Cerro is the Australian dollar. The functional currency of Primero Mining Luxembourg S.a.r.l is the Mexican peso. The functional currency of the parent company, incorporated in Canada, is the Canadian dollar.	
 	 	 	
 		The presentation currency of the Company is the U.S. dollar. The results of the Canadian parent company, Cerro, and Primero Mining Luxembourg S.a.r.l are translated into the U.S. dollar presentation currency as follows: all assets and liabilities are translated at the exchange rate prevailing at the balance sheet date; equity balances are translated at the rates of exchange at the transaction dates, and all items included in the statement of operations are translated using the period average exchange rates unless there are significant fluctuations in the exchange rate, in which case the rate at the date of transaction is used. All differences arising upon the translation to the presentation currency are recorded in the foreign currency translation reserve within other comprehensive income (“OCI”); there is no tax impact of this translation.	
 	 	 	
 	(c)	Measurement uncertainties	
 	 	 	
 		Significant estimates used in the preparation of these financial statements include:	

 	(i)	the economic recoverability of exploration expenditures incurred and the probability of future economic benefits from development expenditures incurred;	
 	 	 	
 	(ii)	the recoverable mineralization and related depreciation and depletion of mining interests;	
 	 	 	
 	(iii)	the proven and probable mineral reserves and resources, as well as exploration potential associated with the mining properties, the expected economic life of the mining properties, the future operating results and net cash flows from the mining properties and the recoverability of the mining properties;	
 	 	 	
 	(iv)	asset carrying values and impairment charges;

 	(v)	the expected costs of reclamation and closure cost obligations;	
 	 	 	
 	(vi)	the assumptions used in accounting for share-based payments; and	
 	 	 	
 	(vii)	the provision for income and mining taxes including expected recovery and periods of reversals of timing differences and composition of deferred income and mining tax assets and liabilities.	
Significant judgments used in the preparation of these financial statements include:

 	(i)	the continuation of Mexican tax laws relative to the APA ruling (Note 7 (b)) and the ability of the Company to continue to pay taxes in Mexico based on realized prices of silver;	
 	 	 	
 	(ii)	accounting and presentation relating to the agreement to sell silver to Silver Wheaton Caymans (Note 5) assumed upon the Company’s acquisition of the San Dimas Mine;	
 	 	 	
 	(iii)	the componentization of buildings, plant and equipment, and the useful lives and related depreciation of these assets;	
 	 	 	
 	(iv)	the useful lives and related depletion of mining properties and leases;	
 	 	 	
 	(v)	the grouping of the San Dimas and Cerro de Gallo assets into Cash Generating Units (“CGU”) and the determination that the Company has two CGUs;	
 	 	 	
 	(vi)	the functional currency of the entities within the consolidated group; and	
 	 	 	
 	(vii)	The determination that the acquisition of Cerro was an asset acquisition rather than a business combination.	
Actual results may differ from these estimates and judgments as the estimation process is inherently uncertain. Actual future outcomes could differ from present estimates and assumptions, and could potentially have material effects on the Company’s’ consolidated financial statements. Revisions to estimates and judgments and the resulting effects on the carrying amounts of the Company’s assets and liabilities are accounted for prospectively.

4.	Changes in accounting policies and future accounting pronouncements	
 	 	
	The Company has adopted the following new and revised standards, along with any consequential amendments, effective January 1, 2013. These changes were made in accordance with the applicable transitional provisions.	
 	 	
	In June 2011, the IASB issued amendments to IAS 1 – Presentation of Financial Statements (“IAS 1”). The amendments are effective for annual periods beginning on or after July 1, 2012. The amendments to IAS 1 require companies preparing financial statements in accordance with IFRS to group together items within OCI that may be reclassified to the profit or loss section of the Consolidated Statement of Operations from those that will not be reclassified. The amendments also reaffirm existing requirements that items in OCI and profit or loss should be presented as either a single statement or two consecutive statements.

(Amounts in tables in thousands of United States dollars unless otherwise stated)	
(Unaudited)	
The Company applied the amendments to IAS 1 effective January 1, 2013 and accordingly has grouped OCI items as required for both the current and comparative period.
In May 2011, the IASB issued IFRS 10 - Consolidated Financial Statements (“IFRS 10”), which supersedes SIC 12 - Consolidation- Special Purpose Entities and the requirements relating to consolidated financial statements in IAS 27 - Consolidated and Separate Financial Statements. IFRS 10 establishes control as the basis for an investor to consolidate its investees and defines control as an investor’s power over an investee with exposure, or rights.
The Company adopted IFRS 10 on January 1, 2013 on a retrospective basis; there has been no impact upon the Company’s financial statements as a result of the adoption.
IFRS 11, Joint Arrangements , supersedes IAS 31, Interests in Joint Ventures, and requires joint arrangements to be classified either as joint operations or joint ventures depending on the contractual rights and obligations of each investor that jointly controls the arrangement. For joint operations, a company recognizes its share of assets, liabilities, revenues and expenses of the joint operation. An investment in a joint venture is accounted for using the equity method as set out in IAS 28, Investments in Associates and Joint Ventures (amended in 2011).
The Company adopted IFRS 11 on January 1, 2013 on a retrospective basis. There was no impact on the Company’s financial statements in the prior period. The Company accounts for its investment in the entity which owns the Cerro del Gallo project as a joint operation.
IFRS 13 Fair Value Measurement (“IFRS 13”) was issued by the IASB in May 2011, and is effective for annual periods beginning on or after January 1, 2013. IFRS 13 was issued to remedy the inconsistencies in the requirements for measuring fair value and for disclosing information about fair value measurement in various current IFRSs. IFRS 13 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.
IFRS 13 relates to how to measure fair value, not what should be measured at fair value. The Company adopted IFRS 13 on January 1, 2013 on a prospective basis. The adoption of IFRS 13 did not require any adjustments to the valuation techniques used by the Company to measure fair value and did not result in any measurement adjustments as at January 1, 2013.
In October 2011, the IASB issued IFRIC 20 - Stripping Costs in the Production Phase of a Mine (“IFRIC 20”). IFRIC 20 clarifies the requirements for accounting for the costs of stripping activities in the production phase of an open-pit mine when two benefits accrue: (i) usable ore that can be used to produce inventory and (ii) improved access to further quantities of material that will be mined in future periods. The IFRIC allows a company to determine a measure to allocate costs between inventory produced and the stripping activity asset; the IFRIC provides examples of measures.
IFRIC 20 is effective for annual periods beginning on or after January 1, 2013. With the acquisition of Cerro on May 22, 2013, the Company acquired a 69.2% interest in the Cerro del Gallo project, which is planned to be an open pit mine. The Company will apply the provisions of IFRIC 20 to the Cerro del Gallo project and develop a policy for allocation of costs once stripping activity begins.

5.	Silver purchase agreement	
 	 	
	In 2004, the owner of the San Dimas Mine entered into an agreement to sell all the silver produced at the San Dimas Mine for a term of 25 years to Silver Wheaton Caymans in return for an upfront payment comprising cash and shares of Silver Wheaton Corp. and a per ounce payment of the lesser of $3.90 (adjusted for annual inflation), or the market price. The Company was required to assume the agreement, with amendments, when it acquired the San Dimas Mine. The amendments provided that for each of the first four years after the acquisition date, the first 3.5 million ounces per annum of silver produced by the San Dimas Mine, plus 50% of the excess silver above this amount, must be sold to Silver Wheaton Caymans at the lesser of $4.04 per ounce (adjusted by 1% per year) and market prices. After four years, for the life of the mine, the first 6 million ounces per annum of silver produced by the San Dimas Mine, plus 50% of the excess silver above this amount, must be sold to Silver Wheaton Caymans at the lesser of $4.20 per ounce (adjusted by 1% per year) and market prices. All silver not sold to Silver Wheaton Caymans is available to be sold by the Company at market prices.	
 	 	
	The expected cash flows associated with the sale of the silver to Silver Wheaton Caymans at a price lower than market price have been reflected in the fair value of the mining interest recorded upon acquisition of the San Dimas Mine. The Company has presented the value of any expected future cash flows from the sale of any future silver production to Silver Wheaton Caymans as part of the mining interest, as the Company did not receive any of the original upfront payment which was made by Silver Wheaton to acquire its interest in the silver production of the San Dimas Mine. Further, the Company does not believe that the agreement to sell to Silver Wheaton Caymans meets the definition of an onerous contract or other liability as the obligation to sell silver to Silver Wheaton Caymans only arises upon production of the silver (Note 3 (c)).	
 	 	
6.	Revenue	
 	 	
	Revenue is comprised of the following sales:

 	 	 	53,793	 	 	38,277	 	 	152,589	 	 	139,342	 	
As described in Note 5, for the first four years post-acquisition of the San Dimas Mine, the Company is entitled to sell 50% of silver production above a 3.5 million ounce annual threshold at market prices. The contract year for the purposes of the threshold runs from August 6 of a year to August 5 of the next year. The Company sold 395,570 ounces and 999,046 ounces of silver, respectively, at market prices during the three and nine months ended September 30, 2013 (2012 - 246,229 ounces and 716,229 ounces).

On October 17, 2011 the Company’s Mexican subsidiary filed an application for an advance pricing agreement (“APA”) with the Mexican tax authorities on the appropriate price for the intercompany sale of silver under the silver purchase agreement. On October 4, 2012, the Mexican tax authorities ruled on the APA. The ruling confirmed that the Company's Mexican subsidiary appropriately recorded revenue and taxes from sales under the silver purchase agreement at realized prices rather than spot prices effective from August 6, 2010.
Under Mexican tax law, an APA ruling is generally applicable for up to a five year period. For Primero this applies to the fiscal years 2010 to 2014. Assuming the Company continues to sell silver from its San Dimas Mine on the same terms and there are no changes in the application of Mexican tax laws relative to the APA ruling, the Company expects to pay taxes on realized prices for the life of the San Dimas Mine.

	On August 6, 2010, in connection with the acquisition of the San Dimas Mine, the Company issued a promissory note for $50 million and a convertible note for $60 million to Desarrolos Mineros San Luis, S.A. de C.V. (“DMSL”), a subsidiary of Goldcorp Inc. (“Goldcorp”). The convertible note was fully repaid in August 2012 through the issuance of 8,422,460 Primero common shares.	
 	 	 	
	The promissory note bears interest at 6% per annum and is repayable in four annual installments of $5 million, starting on December 31, 2011, with the balance of principal due on December 31, 2015. On January 3, 2012, the Company repaid the first $5 million annual installment plus accrued interest of $4.4 million. The second annual installment of $5 million plus accrued interest of $2.8 million was paid on December 31, 2012. In addition to the annual installments, the Company is required to pay 50% of annual excess free cash flow (as defined in the promissory note) against the principal balance. The Company generated excess free cash flow of $15.6 million during the year ended December 31, 2012 and accordingly paid $7.8 million to the note holder in February 2013.	
 	 	 	
11.	Share capital

 	(c)	Stock options	
 	 	 	
 		Under the Company’s stock option plan (“the Rolling Plan”), the number of common shares that may be issued on the exercise of options granted under the plan is equal to 10% of the issued and outstanding shares of the Company at the time an option is granted (less any common shares reserved for issuance under other share compensation arrangements). The majority of options issued typically vest over two years; one third upon the date of grant, one third a year from the grant date, and one third two years from the grant date, however, this is at the discretion of the Board of Directors upon grant. All options are equity-settled and have a maximum term of ten years when granted. Vested options granted under the Rolling Plan will generally expire 90 days after the date that the optionee ceases to be employed by, provide services to, or be a director or officer of, the Company, and any unvested options will terminate immediately. Each employee share option converts into one ordinary share of the Company upon exercise. No amounts are paid or payable by the recipient upon receipt of the option. The options carry neither rights to dividends nor voting rights. Options may be exercised at any time from the date of vesting to the date of their expiry.

 	(d)	Warrants	
 	 	 	
 		As at September 30, 2013 and December 31, 2012, the Company had 20.8 million warrants outstanding which are exercisable to purchase 20.8 million common shares at a price of Cdn $8.00 until July 20, 2015.	
 	 	 	
 		Where warrants were issued as part of a unit or subscription receipt comprised of common shares and warrants, the value assigned to the warrants was based on their relative fair value (as compared to the shares issued), determined using the Black-Scholes pricing model. This value is assigned to the warrant reserve within equity in the consolidated balance sheet.	
 	 	 	
 	(e)	Phantom share unit plans	

 	i)	On May 29, 2010, the Board of Directors approved the establishment of the Company’s Phantom Share Unit Plan (“PSUP”); this is a cash-settled plan and the exercise price of all units is $nil. The amount to be paid out in respect of units which vest under the plan is the volume weighted average price per common share of the Company traded on the Toronto Stock Exchange over the last twenty trading days preceding the vesting date.	
 	 	 	
 		On May 28, 2012 the Company’s shareholders approved the establishment of the Directors PSU plan (“Directors PSUP”). A person holding Director PSUs is entitled to elect to receive, at vesting either (1) a cash amount equal to the volume weighted average trading price per common share over the five preceding trading days, or (2) the number of common shares equal to the number of Directors’ PSUs (subject to the total number of common shares issuable at any time under the Directors’ PSU Plan, combined with all other common shares issuable under any other equity compensation arrangements then in place, not exceeding 10% of the total number of issued and outstanding common shares of the Company). If no election is made, the Company will pay out such Directors’ PSUs in cash.	
 	 	 	
 		The Company issued nil and 814,851 units under the PSUP during the three and nine months ended September 30, 2013 (2012 – 9,026 and 2,578,395 units), and 185,483 units under the Directors PSUP (2012 – 115,384 units). As at September 30, 2013, the Company had 2,733,304 units outstanding under the PSUP with vesting dates between November 8, 2013 and February 25, 2016. These units will be paid out in cash between November 9, 2013 and December 31, 2016. Also outstanding at September 30, 2013 were 262,407 units under the Directors PSUP, which vest and shall be paid in cash or shares between December 1, 2013 and December 31, 2015.	
 	 	 	
 		All of these units have been measured at the reporting date using their fair values. The total amount of expense recognized in the statement of operations and comprehensive income for the three and nine months ended September 30, 2013 in relation to the PSUP and the Directors PSUP was $3.6 million and $5.6 million (2012 - $6.8 million and $8.3 million). The total liability recognized at September 30, 2013 in respect of the PSUP and the Directors PSUP was $9.0 million (December 31, 2012 - $16.9 million), of which $5.5 million (December 31, 2012 - $12.9 million) is classified as a current liability, reported within trade and other payables, with the remaining $3.5 million (December 31, 2012 - $4.0 million) classified as a long-term liability, reported within other long-term liabilities.

 	(i)	Volatility was determined based upon the historic volatility of the Company’s share price over the same period of time as the expected life of the unit.	

 	ii)	On May 8, 2013 the Company’s shareholders approved the establishment of the 2013 PSU plan (“2013 PSUP”). A person holding PSUs issued under this plan is entitled to receive, at vesting either (1) a cash amount equal to the volume weighted average trading price per common share over the five preceding trading days, (2) the number of common shares equal to the number of PSUs (subject to the total number of common shares issuable at any time under the PSU Plan, combined with all other common shares issuable under any other equity compensation arrangements then in place, not exceeding 10% of the total number of issued and outstanding common shares of the Company), or (3) a combination of cash and equity. The choice of settlement is solely at the Company`s discretion.	
 	 	 	
 		During the three and nine months ended September 30, 2013, the Company issued 89,845 and 401,017 2013 PSUP units, respectively (2012 – nil). As at September 30, 2013, the Company had 401,017 units outstanding under the 2013 PSUP with vesting dates between May 10, 2014 and August 12, 2016. These units will be paid out in cash or shares, at the Company`s discretion, between May 11, 2014 and December 31, 2016.	
 	 	 	
 		The 2013 PSUP is accounted for as an equity-settled plan. All of the outstanding units have been measured at the reporting date using their grant date fair value, calculated as the grant date closing price of Primero shares on the TSX. The total amount of expense recognized in the statement of operations and comprehensive income for the three and nine months ended September 30, 2013 in relation to the 2013 PSUP was $0.3 million and $0.4 million.

13.	Capital management	
 	 	
	There have been no significant changes in the Company’s objectives, policies and processes for managing its capital, including items the Company regards as capital, during the three and nine months ended September 30, 2013. The Company manages its common shares, stock options, warrants and debt as capital. The Company’s objectives in managing capital are to safeguard its ability to continue as a going concern in order to provide returns for shareholders and benefits for other stakeholders. To meet this objective, the Company will ensure it has sufficient cash resources to pursue the exploration and development of its mining properties, to fund future production at the San Dimas Mine, development of the Cerro del Gallo project and potential acquisitions.	
 	 	
	To support these objectives the Company manages its capital structure and makes adjustments to it in light of changes in economic conditions and risk characteristics of its underlying assets. To maintain or adjust its capital structure, the Company may attempt to issue shares, issue debt, acquire or dispose of assets or adjust the amount of cash held. The Company does not currently pay out dividends.	
 	 	
	The Company’s investment policy is to invest its cash in highly liquid short-term interest-bearing investments with maturities of 90 days or less from the original date of acquisition, selected with regards to the expected timing of expenditures from continuing operations. The Company is subject to a number of externally imposed capital requirements relating to its debt (Note 10).The requirements are both financial and operational in nature; the Company has complied with all such requirements during the period.	
 	 	
	Pursuant to the terms of the promissory note (Note 10), the Company is required to maintain the following financial covenants:	

 	•	Tangible net worth as at the end of each fiscal quarter of at least $400 million, and	
 	•	Free cash flow of at least $10 million, calculated on a rolling four fiscal quarter basis.

NOTES TO THE CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS	
SEPTEMBER 30 2013	
(Amounts in tables in thousands of United States dollars unless otherwise stated)	
(Unaudited)	

	Tangible net worth means equity less intangible assets. Free cash flow means cash flow from operating activities as reported in the consolidated statement of cash flows, less the aggregate of capital expenditures at the San Dimas Mine, principal and interest on the promissory note and up to $5 million per year on account of acquisition opportunities.	
 	 	
14.	Financial instruments	
 	 	
	The Company’s financial instruments at September 30, 2013 consist of cash, trade and other receivables, trade and other payables, and debt.	
 	 	
	At September 30, 2013 the carrying amounts of cash, trade and other receivables, trade and other payables are considered to be reasonable approximation of their fair values due to their short-term nature.	
 	 	
	The fair value of the promissory note upon initial recognition was considered to be its face value and the promissory note has subsequently been carried at amortized cost. At September 30, 2013, the fair value of the promissory note was $33.9 million using a discounted future cash-flow analysis.	
 	 	
15.	Related party transactions	
 	 	
	Transactions with Goldcorp Inc.	
 	 	
	At September 30, 2013, Goldcorp owned approximately 27% of the Company’s common shares. The Company has a promissory note outstanding to a wholly-owned subsidiary of Goldcorp (Note 10). Interest accrues on the promissory note and is recorded within trade and other payables. A payment of $5 million plus accrued interest of $4.4 million was paid under the terms of the Promissory note on January 3, 2012. The second annual installment of $5 million plus accrued interest of $2.8 million was paid on December 31, 2012. In addition to the annual installments, the Company paid $7.8 million against the principal balance on February 21, 2013, in compliance with the free cash flow covenant contained in the promissory note. In addition, DMSL owns 30.8% of the entity which owns the Cerro de Gallo project.	
 	 	
	During the three and nine months ended September 30, 2013, $0.1 million and $0.3 million (2012 - $0.6 million and $2.2 million) was paid to DMSL for the purchase of equipment, equipment leasing fees and services received under a transition services agreement between the Company and DMSL. These amounts are considered to be at fair value. As at September 30, 2013, the Company had an amount payable of $2.5 million owing to DMSL (December 31, 2012 - $2.3 million). As at September 30, 2013, the Company had an amount receivable from Goldcorp Inc. of $nil (December 31, 2012 - $0.3 million).

16.	Social security payments	
 	 	
	When Primero acquired the San Dimas Mine in August 2010, a potential liability was known to exist related to the registration of employees at San Dimas under the Mexican social security system (“IMSS”). Mexico has a legal requirement that employees are registered for IMSS and that their employers pay premiums under the IMSS. The employees were not registered because government provided social security benefits were not available in the vicinity of the mine due to the remoteness of the location. Instead benefits were provided by the employer, DMSL. After the acquisition of the mine, Primero continued to provide social security benefits to its Mexican employees.	
 	 	
	The Company was in talks with the IMSS authority for about two years and the recent change in federal government brought matters to a conclusion. The outcome was that effective June 1, 2013 all of the Mexican employees were registered for IMSS and the Company is paying social security premiums on their behalf. In addition, on July 23, 2013, the IMSS authority notified the Company that it would be assessed $6.9 million in respect of past amounts due (including penalties and interest), dating back to August 2010. Consequently the Company accrued $6.9 million in its financial statements as at June 30, 2013. The amount that relates to 2013 ($1.4 million) has been charged to operating expenses while the amount that relates to 2012 and earlier years ($5.5 million) has been charged to other expenses in the statement of operations. The Company fully paid the accrued liability in August 2013.

18 .	Commitments and contingencies	
 	 	 	
	(a)	An Ejido is a communal ownership of land recognized by the federal laws in Mexico. While mineral rights are administered by the federal government through federally issued mining concessions, access to surface rights is also required for mining operations. An Ejido controls surface rights over its communal property through a board of directors. An Ejido may sell or lease lands directly to a private entity and it may also allow individual members of the Ejido to obtain title to specific parcels of land and thus the right to sell or lease the land.	
 	 	 	
		The San Dimas Mine uses Ejidos’ lands pursuant to written agreements with Ejidos. Some of these agreements may be subject to renegotiation and changes to the existing agreements may increase operating costs or have an impact on operations. In cases where access to land is required for operations and an agreement cannot be reached with the land owner, Primero may seek access under Mexican law which provides for priority rights for mining activities.	
 	 	 	
		Four of the properties included in the San Dimas Mine and for which Primero holds legal title are subject to legal proceedings commenced by Ejidos seeking title to the property. None of the proceedings name Primero as a party and Primero therefore has no standing to participate in them. In all cases, the defendants are previous owners of the properties, either deceased individuals who, according to certain public deeds, owned the properties more than 80 years ago, corporate entities that are no longer in existence, or Goldcorp companies. Three of the proceedings also name the Tayoltita Property Public Registry as co-defendant.

NOTES TO THE CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS	
SEPTEMBER 30 2013	
(Amounts in tables in thousands of United States dollars unless otherwise stated)	
(Unaudited)	

 		While Primero cannot intervene in these proceedings, in the event that a final decision is rendered in favour of the Ejido, Primero may seek to annul the decision or commence an action as an affected third party on the basis that it is the legitimate owner and is in possession of the property. If Primero is not successful in its challenge, the San Dimas Mine could face higher costs associated with agreed or mandated payments that would be payable to the Ejidos for use of the properties.	
 	 	 	
 		There has been no material change in this contingency during the three and nine months ended September 30, 2013.	
 	 	 	
 	(b)	As at September 30 2013, the Company had entered into commitments to purchase plant and equipment totaling $12.3 million (December 31, 2012 - $3.7 million).	
 	 	 	
 	(c)	Due to the size, complexity and nature of the Company’s operations, various legal and tax matters arise in the ordinary course of business. The Company accrues for such items when a liability is both probable and the amount can be reasonably estimated. In the opinion of management, any potential charges not yet accrued will not have a material effect on the consolidated financial statements of the Company.	

19 .	Subsequent events	
 	 	 	
	(a)	On October 14, 2013, the Company announced that ASX Limited approved the Company’s request for its removal from the official list of the Australian Securities Exchange. The Company's decision was based on the low volume of trading of its CHESS Depositary Interests ("CDIs") on the ASX compared to common shares on the TSX and NYSE. Since listing on the ASX in May 2013, the CDIs held on the Australian register have declined from approximately 14% of the Company’s total issued share capital to less than 7% as at October 1, 2013. As a result, the Company determined that sustaining the administrative and compliance costs of an ASX listing was not in the interests of Primero and all of its shareholders. The date on which the Company will be removed from the official list will be December 30, 2013.	
 	 	 	
	(b)	The Company has entered into a binding letter of intent with a subsidiary of Goldcorp Inc. to acquire the remaining 30.8% interest in the Cerro del Gallo project. The closing date for the acquisition (the “Closing Date”) is expected to be before December 31, 2013. The consideration comprises an upfront payment of $8 million, plus contingent payments based on meeting certain milestones or market conditions. The contingent payments include $8 million (the “First Contingent Payment”) after achieving commercial production on the Phase I heap leach operation; $5 million if the date of the First Contingent Payment occurs before the fifth anniversary of the Closing Date and the gold price averages $1,500 per ounce for a consecutive 30 day period within one year following the date of the First Contingent Payment, and not later than the fifth anniversary of the closing date; $14 million (“the Second Contingent Payment”) on announcement of a decision by Primero to construct a carbon-in- leach mill for Phase II, and $5 million if the date of the Second Contingent Payment occurs before the fifth anniversary of the Closing Date and the gold price averages $1,500 per ounce for a consecutive 30 day period within one year following the date of the Second Contingent Payment, and not later than the fifth anniversary of the closing date.

PRIMERO REPORTS THIRD QUARTER 2013 RESULTS;
RECORD QUARTERLY GOLD AND SILVER PRODUCTION LEAD TO 2013 PRODUCTION GUIDANCE INCREASE
(Please note that all dollar amounts in this news release are expressed in U.S. dollars. Refer to the third quarter 2013 management discussion and analysis (MD&A) and audited financial statements for more information.)
Toronto, Ontario, November 6, 2013 – Primero Mining Corp. (“Primero” or the “Company”) (TSX:P, NYSE:PPP, ASX:PPM) today reported financial and operational results for the third quarter ended September 30, 2013.
Third Quarter Highlights:
·	Record Production : Gold equivalent 1 production increased by 64% over the same period last year to 41,998 gold equivalent ounces (gold production of 31,791 ounces and silver production of 1.62 million ounces).
 
·	Low Cash Costs and All-in Sustaining Costs : Cash costs 2 dropped by 26% over the same period last year to $516 per gold equivalent ounce, or $252 per gold ounce on a by-product basis; with all-in sustaining costs 2 of $974 per ounce.
 
·	Highest Spot Silver Sales: Sold 999,046 ounces of silver at spot prices in 2013, 40% more than 2012.
 
·	Strong Earnings and Cash Flow: Adjusted net earnings 3 of $11.0 million ($0.09 per share) and operating cash flow before working capital changes 4 of $20.9 million ($0.18 per share).
 
·	Balance Sheet Remains Strong: Cash position of $125.7 million at September 30, 2013.
 
·	Increased Production Guidance: Production guidance increased to 135,000 to 140,000 gold equivalent ounces, up to 26% higher than 2012.
 
·	Exploration Success Continues: Extended the Victoria and Alexa veins and discovered a potential new high-grade vein in the West Block.
1

Subsequent to Third Quarter:
·	Cerro del Gallo Ownership Consolidated: Binding letter of intent in place with Goldcorp Inc. to acquire the remaining 30.8% interest in the gold-silver-copper Cerro del Gallo project.
“San Dimas and our operating team continue to deliver record results,” stated Mr. Joseph F. Conway, President and Chief Executive Officer. “We exceeded our expectations during the quarter and as a result have increased our production guidance for a second time this year. Productivity has continued to improve on a quarter over quarter basis and we are on schedule to achieve the expanded rate of 2,500 TPD during the first quarter of 2014. We are also improving mining dilution and the results are evident in our grades. Despite substantially lower commodity prices, Primero’s financial results remain very strong highlighting the benefits of a high-margin operation such as San Dimas. I am proud of our productivity improvement achievements to date, which we will continue to focus on across the organization. The ownership consolidation of our Cerro del Gallo project is in line with our stated objectives and we will spend $15 million in 2013 to optimize and advance the project through engineering and metallurgical studies, land acquisition and drilling.”
Grade Drives Strong Production
Primero produced 41,998 gold equivalent ounces 1 during the third quarter of 2013 or 31,791 ounces of gold and 1.62 million ounces of silver, 68% more and 42% more, respectively, than the same period in 2012. The increase in gold production was due to a 49% higher gold grade of 5.08 grams per tonne, a 26% higher silver grade and 12% higher throughput. Throughput in Q3 2013 was slightly lower than Q2 2013 mainly due to scheduled maintenance of the ball mills.
Higher gold and silver grades during the third quarter of 2013 were partially a result of mining high-grade pillars as well as a reduction in overall mining dilution. Mining of pillars is part of the ongoing San Dimas mine plan, but this is not expected to contribute as meaningfully to Q4 2013 production.
A total of 198,222 tonnes was mined during the third quarter of 2013, compared to 173,475 tonnes in the same period in 2012. The Company utilized a small portion of the low-grade ore stockpile built during the second quarter of 2013, to result in 199,812 tonnes milled. The Company successfully kept mine throughput above the current mill capacity during the third quarter at an average of 2,172 tonnes per day (“TPD”).
Total cash costs 2 on a gold equivalent and by-product basis in the third quarter 2013 were $516 and $252 per ounce, respectively, compared with $699 and $363 per ounce, respectively, in the third quarter 2012.
Earnings and Cash Flow Remain Strong
Revenue in the third quarter of 2013 was $53.8 million, 40% higher than the same period in 2012, as a result of selling 30,261 ounces of gold at an average realized price of $1,338 per ounce, and 1.58 million ounces of silver at an average realized price of $8.42 per ounce 5 . Revenue was $38.3 million for the same period in 2012 from selling 17,100 ounces of gold at an average realized price of $1,646 per ounce and 1.05 million ounces of silver at an average realized price of $9.66 per ounce.
The Company sold 395,570 ounces of silver at an average realized spot price of $21.18 in Q3 2013 compared with 246,229 ounces at an average realized spot price of $27.70 in Q3 2012. The annual silver threshold under the silver purchase agreement 5 was reset on August 6, 2013 and the Company sold 1.18 million ounces at an average price of $4.16 per ounce in Q3 2013 under the silver purchase agreement, compared with 0.8 million ounces at $4.12 per ounce in Q3 2012. The Company anticipates that it will continue to maintain a similar exposure to spot silver sales as the increase in the silver purchase agreement annual threshold from 3.5 million ounces to 6.0 million ounces on August 6, 2014 coincides with the potential expansion of the San Dimas mill to 3,000 TPD.

The Company earned net income of $10.1 million ($0.09 per share) for the three months ended September 30, 2013 compared with net income of $11.6 million ($0.12 per share) for the three months ended September 30, 2012. Significantly higher gold and silver production and sales offset the substantially lower realized commodity prices and increased revenue and earnings from mine operations in the Q3 2013, compared with Q3 2012. Lower general and administrative expenses, due primarily to reduced share-based payment expense in Q3 2013 than Q3 2012, were offset by higher income tax expense in Q3 2013 primarily due to the impact of foreign exchange changes on deferred tax balances. Net income per share in Q3 2013 was also impacted by a 24% increase in the number of weighted average shares outstanding due mainly to the issue of approximately 18 million shares in Q2 2013 to acquire 69.2% of the Cerro del Gallo project.
Adjusted net income 3 , which primarily excludes the impact of foreign exchange changes on deferred tax balances in both periods, was $11.0 million ($0.09 per share) for the third quarter 2013, compared with $2.6 million ($0.03 per share) for the same period in 2012.
Operating cash flow before working capital changes 4 in the third quarter of 2013 was $20.9 million ($0.18 per share), compared to $15.4 million ($0.17 per share) in 2012.
Revenue was $152.6 million for the nine months ended September 30, 2013 as a result of selling 80,689 ounces of gold at an average realized price of $1,445 per ounce, and 4.48 million ounces of silver at an average realized price of $8.03 per ounce. Revenue was $139.3 million for the same period in 2012 from selling 64,980 ounces of gold at an average realized price of $1,643 per ounce and 3.76 million ounces of silver at an average realized price of $8.65 per ounce.
The Company reached the 3.5 million ounce annual threshold under the silver purchase agreement 5 in early April 2013 and sold 999,046 ounces of silver at an average spot price of $21.60 per ounce in the nine months ending September 30, 2013. In the prior year, the 3.5 million ounce annual threshold was met at the end of April and the Company sold 716,229 ounces of silver at an average spot price of $28.03 per ounce in the nine months ending September 30, 2012.
The Company earned net income of $31.6 million ($0.30 per share) for the nine months ended September 30, 2013 compared with $48.3 million ($0.54 per share) for the nine months ended September 30, 2012. Higher sales volumes were offset by lower commodity prices and higher operating expenses. The accrual of a $5.5 million liability for historical social security premiums, covering the period from the acquisition of the San Dimas mine in August 2010 to the end of 2012, also reduced earnings for the nine months ended September 30, 2013 (see Other expense below). Net income was further impacted by higher income tax expense, due to the impact of foreign exchange changes on deferred tax balances and net income per share was reduced by an 18% increase in the number of weighted average shares outstanding due mainly to the issue of approximately 18 million shares in May 2013 to acquire 69.2% of Cerro del Gallo.
Adjusted net income, which primarily excludes the accrual for historical social security premiums in 2013 and the impact of foreign exchange changes on deferred tax balances in both years, was $37.1 million ($0.35 per share) for the nine months ended September 30, 2013, compared with $36.8 million ($0.41 per share) for the same period in 2012.
Operating cash flow before working capital changes 4 for the nine months ended September 30, 2013 was $56.9 million ($0.54 per share), compared to $70.9 million ($0.79 per share) in 2012, primarily as a result of higher sales volumes being offset by lower commodity prices and slightly higher operating expenses.

Cash Position Remains Strong
The Company’s cash position was $125.7 million at September 30, 2013 down from the June 30, 2013 balance of $130.4 million. The cash balance of $125.7 million reflects $21.5 million in capital expenditures, $6.9 million in historical social security premiums and a payout of $7.1 million for Phantom Share Units during the third quarter of 2013.
With its cash balance and anticipated cash flows at current commodity prices, Primero’s management believes the Company is fully funded to expand production at San Dimas and build the Cerro del Gallo project if a positive construction decision is made, while remaining well positioned to take advantage of strategic growth opportunities. In order to further enhance its financial flexibility, the Company is in negotiations with major financial institutions to secure a revolving line of credit of $75 million, which it expects to complete in Q4 2013.
Outlook for 2013 Revised Upward a Second Time
Based on better than anticipated operating results in the third quarter Primero has increased its production guidance to between 135,000 and 140,000 gold equivalent ounces, an increase of up to 26% over 2012, based on higher throughput at slightly higher grades. The Company now expects its gold only production to be in the range of 105,000 and 110,000 ounces and has maintained its silver production guidance of between 5.6 million and 6.0 million ounces.
Cash costs for 2013 are expected to be at the lower end of the guidance range of $620 to $640 per gold equivalent ounce, or between $410 and $430 per gold ounce on a by-product basis.
Primero’s 2013 revised outlook is summarized in the following table:

 	Previous Outlook 2013	Revised Outlook 2013	
Attributable gold equivalent production 1
(gold equivalent ounces)	125,000-135,000	135,000-140,000	
Gold production
(ounces)	95,000-105,000	105,000-110,000	
Silver production 5
(ounces)	5,600,000-6,000,000	5,600,000-6,000,000	
Silver sales at spot prices 5
(ounces)	850,000-950,000	999,046	
Total cash costs 2
(per gold equivalent ounce)	$620 - $640	$620 - $640	
Total cash costs 2 - by-product
(per gold ounce)	$410 - $430	$410 - $430	
All-in Sustaining Costs 2
(per gold ounce)	$1,050 - $1,150	$1,050 - $1,150	
Material assumptions used to forecast total cash costs for 2013 include: an average gold price of $1,410 per ounce, revised downwards from the original estimate of $1,700 per ounce; an average silver price of $6.77 per ounce, revised downwards from $8.52 per ounce (calculated using the silver agreement contract price of $4.14 per ounce and assuming excess silver beyond contract requirements is sold at an average silver price of $21.16 per ounce, revised downwards from $30 per ounce); and foreign exchange rates of 1.00 Canadian dollars and 13 Mexican pesos to the US dollar.

San Dimas Expansion to 2,500 TPD On Track for Q1 2014
The Company’s expansion of San Dimas from 2,150 TPD to 2,500 TPD is on track for commissioning during the first quarter of 2014. At September 30, 2013 the expansion of the mill to 2,500 TPD was 70% complete. Mine development to feed the mill also remains on track to be completed during the first quarter of 2014.
The Company has continued to review the opportunity to further expand the San Dimas mine to 3,000 TPD. With over 100 years of operating history and the proven ability to replace reserves, the Company is confident that operating San Dimas at 3,000 TPD is possible.
Since it acquired the San Dimas mine in August 2010 the Company has expanded throughput from approximately 1,600 TPD to the scheduled 2,500 TPD in Q1 2014. It has also introduced long-hole mining that has contributed to an improvement in mining dilution and seen average grades increase over the last four quarters. The Company has also successfully replaced depletion and added additional resources each year through exploration.
After analyzing the current reserves and resources and mine sequencing at San Dimas, the Company has elected to remain prudent with its capital allocation and has deferred a decision regarding a further expansion to 3,000 TPD until sufficient new mining faces can be identified.
The Company will continue to explore and assess the potential expansion to 3,000 TPD and will provide an update no later than mid-2014.
Cerro Del Gallo Project Ownership Consolidated
The Company announced today that it has agreed to acquire from a subsidiary of Goldcorp the outstanding 30.8% interest in its Cerro del Gallo, for an upfront payment of $8 million plus a contingent payment of $8 million based on the Phase I heap leach operation achieving commercial production, plus a contingent payment of $5 million based on the gold price returning to $1,500 per ounce over a consecutive 30 day period, within five years of the anniversary date of the transaction, plus contingent payments based on a construction decision to build the potential Phase II CIL mill operation. Please refer to the third quarter 2013 MD&A for further details of the agreement.
On May 22, 2013 Primero closed the acquisition of Cerro Resources NL ("Cerro"), resulting in 69.2% ownership of the Cerro del Gallo gold-silver-copper project in Guanajuato, Mexico 6 .
The Cerro del Gallo project acquired in May, 2013 is the Company’s only development project and has the potential to increase the Company’s near-term production by approximately 95,000 gold equivalent ounces per year. In order to consolidate its ownership position, eliminate the joint venture agreement reducing administrative costs and eliminate a potential 10% Net Profit Interest (“NPI”) on the project, the Company has negotiated the purchase of the outstanding 30.8% interest in the Cerro del Gallo project.
Following the acquisition of the Cerro del Gallo project in May 2013 the Company commenced an assessment of the alternatives for the long term development of the project. The May 2012 Definitive Feasibility Study ("DFS") 7 on the project contemplated only a phase one ("Phase I") heap leach of 4.5 million tonnes per year of oxidized and partially oxidized ore for 7.2 years of production. The May 2012 DFS superseded an earlier preliminary assessment in May 2011, that identified a potential phase two ("Phase II") addition of carbon-in-leach ("CIL") processing of fresh rock commencing in the fifth year. Further drilling is part of this assessment program and will focus on the detailed metallurgical characterization of the transition zone as well as the unoxidized mineralization at depth and lateral to the ore zone currently considered in the Phase I development plan. The exploration work also being conducted concurrently will be an important component for the development decision.
5

As a result of the significant decline in the gold price and the recent tax reforms in Mexico, the Company elected to critically review and refine the capital expenditures for the development of the Cerro del Gallo project. The Company’s 2013 budget for Cerro del Gallo is $15 million including $4 million for exploration and condemnation drilling. This spending is expected to be sufficient to complete all outstanding permitting, land acquisition, basic engineering of the mine processing facilities and a preliminary exploration program, including condemnation drilling. The Company expects to be in a position to make a construction decision by the end of 2013.
During the third quarter 2013 the Company increased its land ownership position to 58% of its targeted land holdings, including all land covering the proposed open pit, heap leach pads, crushing plant, the wet processing plant, the waste pad and environmental pond as well as a natural buffer area surrounding the mine. All required water rights have been secured and work has started on securing the electrical connection to the national power grid.
There have been three drill rigs operating on the property since August 2013. The Company expects to complete 8,100 metres of in-fill drilling, 3,900 metres of condemnation drilling plus 4,200 metres of metallurgical and environmental drilling before the end of 2013.
San Dimas Shows Continued Exploration Success
On September 19, 2013 Primero announced exploration results that continue to extend the known mineralization in both the Victoria and Alexa veins and identified what is another new high-grade vein in the West Block 8 .
Since the Company discovered the Alexa and Victoria veins in the Sinaloa Graben block in the first half of 2012, 105,000 ounces of gold and 5.6 million ounces of silver were included in the year-end 2012 Mineral Reserve estimate.
Due to their close proximity to existing infrastructure, the Company successfully developed access to the Alexa and Victoria veins within a year and these veins have already contributed a meaningful portion of production in 2013.
The Company also announced that it had expanded its San Dimas exploration program to a total of 89,000 metres of drilling in 2013 for the same $15 million budget as its original program of 73,000 metres as a result of improved productivity achieved during the year.
Primero to Delist from the Australian Securities Exchange (“ASX”)
On October 14, 2013 9 , the Company announced that ASX Limited approved the Company’s request for its removal from the official list of the Australian Securities Exchange. The Company's request to delist was based on the low volume of trading of its CHESS Depositary Interests ("CDIs") on the ASX compared to common shares on the TSX and NYSE. Since listing on the ASX in May 2013, the CDIs held on the Australian register have declined from approximately 14% of the Company’s total issued share capital to less than 7% as at October 1, 2013. As a result, the Company determined that sustaining the administrative and compliance costs of an ASX listing was not in the interests of Primero and all of its shareholders. The date on which the Company will be removed from the official list will be December 30, 2013. Details of the delisting process were mailed to CDI holders on October 24, 2013, and are available on the Company’s website.

This release should be read in conjunction with Primero’s third quarter 2013 financial statements and MD&A report on the Company's website, www.primeromining.com, in the “Financial Reports” section under “Investors”, or on the SEDAR website at www.sedar.com , or on the Edgar website www.sec.gov .
(1) “Gold equivalent ounces” include silver ounces produced, and converted to a gold equivalent based on a ratio of the average commodity prices realized for each period. The ratio for the third quarter 2013 was based on realized prices of $1,338 per ounce of gold and $8.42 per ounce of silver. The ratio used for the 2013 guidance projection was based on estimated average prices of $1,410 per ounce of gold and $6.77 per ounce of silver.
(2) Total cash costs per gold equivalent ounce, total cash costs on a by-product basis and all-in sustaining costs are non-GAAP measures. Total cash costs per gold equivalent ounce is defined as cost of production (including refining costs) divided by the total number of gold equivalent ounces produced. Total cash costs on a by-product basis are calculated by deducting the by-product silver credits from operating costs. The Company reports total cash costs on a production basis. “All-in sustaining costs”, as defined by the World Gold Council, more fully defines the total costs associated with producing gold. All-in sustaining costs include by-product cash costs, sustaining capital expenditures, corporate administrative expense, exploration and evaluation costs, reclamation cost accretion and is reported on a production basis. In the gold mining industry, these are common performance measures but do not have any standardized meaning, and are non-GAAP measures. The Company follows the recommendations of the Gold Institute standard for total cash costs and the World Gold Council standard for all-in sustaining costs. The Company believes that, in addition to conventional measures, prepared in accordance with GAAP, certain investors use this information to evaluate the Company’s performance and ability to generate cash flow. Accordingly, it is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. See the third quarter 2013 MD&A for a reconciliation of total cash costs to reported operating expenses (the nearest GAAP measure).
(3) Adjusted net income and adjusted net income (loss) per share are non-GAAP measures. Neither of these non-GAAP performance measures has any standardized meaning and is therefore unlikely to be comparable to other measures presented by other issuers. The Company believes that, in addition to conventional measures prepared in accordance with GAAP, the Company and certain investors use this information to evaluate the Company’s performance. Accordingly, it is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. Refer to the third quarter 2013 MD&A for a reconciliation of adjusted net income (loss) to reported net income (loss).
(4) “Operating cash flow” is operating cash flow before working capital changes. This and operating cash flows before working capital changes per share are non-GAAP measures which the Company believes provides a better indicator of the Company’s ability to generate cash flow from its mining operations. See the third quarter 2013 MD&A for a reconciliation of operating cash flows to GAAP.
(5) According to the silver purchase agreement between the Company and Silver Wheaton Corp., until August 6, 2014 Primero will deliver to Silver Wheaton a per annum amount equal to the first 3.5 million ounces of silver produced at San Dimas and 50% of any excess at $4.16 per ounce (increasing by 1% per year). Thereafter Primero will deliver to Silver Wheaton a per annum amount equal to the first 6.0 million ounces of silver produced at San Dimas and 50% of any excess at $4.20 per ounce (increasing by 1% per year). The Company will receive silver spot prices only after the annual threshold amount has been delivered.
(6) See Primero News Release “Primero Announces Closing of Cerro Del Gallo Acquisition” dated May 22, 2013.
(7) Refer to “Technical Report, First Stage Heap Leach Feasibility Study, Cerro del Gallo Gold Silver Project, Guanajuato, Mexico, Effective Date: 11th May 2012, Report Date: 29th June 2012” filed on www.sedar.com .

As a result of restructuring the silver purchase agreement on August 6, 2010, Primero is able to sell some silver production at spot prices, subject to minimum threshold amounts being met 5 .	
 	 	
(2)	Total cash costs per gold ounce on a gold equivalent and by-product basis and all-in sustaining cash costs are non-GAAP financial measures. Refer to “Non-GAAP measure – Total cash costs per gold ounce calculation” in the Company’s third quarter 2013 MD&A for a reconciliation to operating expenses.
