1 SUMMARY
EXECUTIVE SUMMARY
Roscoe Postle Associates Inc. (RPA) was retained by Barrick Gold Corporation (Barrick) to prepare an independent Technical Report on the Veladero Gold Mine (the Project) in Argentina. The purpose of this report is to support public disclosure of Mineral Resource and Mineral Reserve estimates at the Project as of December 31, 2013. This Technical Report conforms to NI 43-101 Standards of Disclosure for Mineral Projects. RPA visited the property from February 10 to 12, 2014.
Barrick is a Canadian publicly traded mining company with a large portfolio of operating mines and projects across four continents. Veladero is a large open pit, heap leach gold and silver mine in the high Andes Cordillera of central western Argentina. Operations include open pit mining of gold-silver ore from two mining areas, two-stage crushing, and extraction of precious metals using valley-fill heap leaching and Merrill-Crowe recovery. Since Veladero started production in 2005, the mine has recovered over five million ounces of gold and over eleven million ounces of silver from approximately 204 million tonnes of ore averaging 1.2 g/t Au and 16 g/t Ag.
Mining at Veladero will average approximately 30 million tonnes per annum (Mtpa) of Mineral Reserves over the next six years. Barrick operates the mine through its wholly-owned subsidiary Minera Argentina Gold S.A. (MAGSA).
Table 1-1 summarizes the Mineral Resources at Veladero as of December 31, 2013.

CONCLUSIONS
Based on the site visit and subsequent review, RPA offers the following conclusions:
MINERAL RESOURCE ESTIMATION
 
 	•	 	The 2013 year-end (EOY2013) Measured and Indicated Mineral Resources, exclusive of Mineral Reserves, total 164.4 million tonnes averaging 0.68 g/t Au and 12.8 g/t Ag and contain 3.6 million ounces of gold and 67.9 million ounces of silver.	
 
 	•	 	The EOY2013 Inferred Mineral Resources total 27.9 million tonnes averaging 0.30 g/t Au and 12.9 g/t Ag and contain 269,000 ounces of gold and 11.6 million ounces of silver.	
 
 	•	 	Essentially all of the remaining resources and reserves are found in the Veladero area within the Filo Federico and Cuatro Esquinas zones.	
 
 	•	 	The resource estimate gold cut-off grades range from 0.20 g/t for run-of-mine (ROM) material from the Filo Federico pit Type 1 material to 0.48 g/t for Filo Federico pit Type 2 material, which requires crushing.

Technical Report NI 43-101 – March 27, 2014	  	Page 1-2  	

			
	  	www.rpacan.com	

 	•	 	Mineral Resource estimates have been prepared utilizing acceptable estimation methodologies. The classification of Measured, Indicated, and Inferred Resources conform to Canadian Institute of Mining, Metallurgy and Petroleum Definition Standards for Mineral Resources and Mineral Reserves dated November 27, 2010 (CIM definitions).	
 
 	•	 	The current drill hole database is reasonable for supporting a resource model for use in Mineral Resource and Mineral Reserve estimation.	
 
 	•	 	The methods and procedures utilized to gather geological, geotechnical, assaying, density, and other information are reasonable and meet generally accepted industry standards. Standard operating protocols are well documented and updated on a regular basis for most of the common tasks. The mine carries out regular comparisons with blast hole data, previous models, and production reconciliation results to calibrate and improve the resource modelling procedures.	
 
 	•	 	The resource model demonstrates a positive bias when reconciled against the grade control model in 2013 due mostly to new high grade mineralized structures defined by the blast holes that were generally not intersected in the exploration drill holes. Although finding unexpected high grade mineralization in the pit is certainly a very positive outcome for Veladero, it may be difficult to make significant adjustments to the resource model without new drilling data. It is unknown for how long this positive reconciliation will continue. RPA concurs with Barrick’s plan to use the recently completed structural interpretation along with new geostatistical and other strategies to improve the resource model in the areas where higher than expected grades were encountered.	
 
 	•	 	Exploration and development sampling and analysis programs use standard practices, providing generally reasonable results. The resulting data can effectively be used for the estimation of Mineral Resources and Mineral Reserves.	
 
 	•	 	Overall, RPA is of the opinion that MAGSA has done high quality work that exceeds industry practice.	
MINING AND MINERAL RESERVES
 
 	•	 	The EOY2013 Proven and Probable Reserves are estimated to be 186.6 million tonnes at 0.85 g/t Au and 14.8 g/t Ag, containing 5.1 million ounces of gold and 89 million ounces of silver.	
 
 	•	 	The Mineral Reserve estimates have been prepared utilizing acceptable estimation methodologies and the classification of Proven and Probable Reserves conform to CIM definitions.	
 
 	•	 	Recovery and cost estimates are based on actual operating data and engineering estimates.	
 
 	•	 	Economic analysis of the Veladero Life of Mine (LOM) plan generates a positive cash flow and, in RPA’s opinion, meets the requirements for statement of Mineral Reserves. In addition to the Mineral Reserves in the LOM plan, there are Mineral Resources that represent opportunities for the future.	
 
 	•	 	The economic pit limits are very sensitive to an increase in reserve gold price of 10%, while they are not very sensitive to a decrease in reserve gold price of 10%, indicating the current LOM plan is strong with potential for expansion in the future if market conditions were to stabilize or improve.

PROCESS
 
 	•	 	The crushing circuit and conveyor circuit had lower than expected availability due to equipment maintenance issues. The ore is quite abrasive, resulting in frequent liner changes, which reduces availability. Measures are being implemented in an attempt to improve operations.	
 
 	•	 	The overland conveyor has experienced more downtime than desired. The conveyor being down results in mine trucks having to be diverted to transfer leach pad material from the crushing plant.	
 
 	•	 	With the curtailment of mercury sales, long term storage will be required, and is being addressed.	
 
 	•	 	Senior supervision in the plant has been replaced in the last few months. It is anticipated that the new team will be effective in increasing operational availability.	
ENVIRONMENTAL CONSIDERATIONS
 
 	•	 	Veladero has an Environmental Management Plan that is certified under the ISO 14001 standards. It is audited annually and was re-certified in 2013.	
 
 	•	 	In March 2013, as a result of an administrative investigation, the Ministry of Mines in the Province of San Juan issued a permit amendment restricting the amount of fresh water that can be used at the Project’s heap leach pad. Barrick expects the restrictions to be removed shortly, however, failure to obtain approvals in a timely manner will have an increasing impact on 2014 production. In RPA’s opinion, it is reasonable to assume that the current situation will be resolved in a timely manner, thus not impacting the current Mineral Resource and Mineral Reserve estimates.	
 
 	•	 	Veladero is certified by the International Cyanide Management Code. Re-certification occurs annually and Veladero was re-certified in May 2013.	
 
 	•	 	Mine closure plans are reviewed and analyzed annually. Current cost estimates for closure at Veladero are approximately US$59 million.	
RECOMMENDATIONS
RPA makes the following recommendations:
GEOLOGY AND MINERAL RESOURCES
 
 	•	 	The resource modelling work is very good and no significant procedural changes are warranted. The resource model, however, significantly under-predicted the gold produced in 2013 due to unexpected high grade mineralization in the Filo Federico pit. RPA concurs with Barrick’s plans to use the recently completed structural interpretation along with new geostatistical and other strategies to improve the resource model in the areas where higher than expected grade was encountered.

TECHNICAL SUMMARY
PROPERTY DESCRIPTION AND LOCATION
The Veladero Mine is located on the east flank of the Andes Cordillera, six kilometres east of the Chile/Argentina border. The mine site is at approximately 29°22’ South latitude and 69°57’ West longitude in the Department of Iglesia, San Juan Province, northwest Argentina. The closest major population and commercial center is the provincial capital of San Juan, which is approximately 360 km by road. Elevations at the mine range from 3,900 m to 4,800 m.
LAND TENURE
Since 1989, Instituto Provincial de Exploraciones y Explotaciones Mineras de la Provincia de San Juan (IPEEM) has been the provincial mining entity responsible for holding title to certain of the San Juan Province’s mineral rights, and for soliciting and administering bids for exploration and mining licences in the province. Therefore, some of the mining licences are held by IPEEM. The remainder of the mining licences are held by MAGSA. RPA notes that Barrick Exploraciones Argentina S.A. (BEASA) controls an extensive land package in the district that is contiguous with the mine concessions. This report summarizes only the mining and surface rights that are directly related to the Veladero Mine.

The Veladero Mine comprises the following mining properties: (i) the Veladero mining group, consisting of eight mining concessions owned by IPEEM and operated by MAGSA, now a subsidiary of Barrick in Argentina, pursuant to applicable provincial law and the Exploitation Contract between IPEEM and MAGSA (as amended) and (ii) the Filo Norte mining group, consisting of five mining concessions owned by MAGSA, which are: Ursulina Sur, Florencia 1, Gaby M, Río 2, and Río 3. The Veladero mining properties cover an area of approximately 14,420 hectares.
Pursuant to the Argentina Mining Code, mining concessions do not have an expiry date; however, to keep them in good standing, concession holders are required to pay certain annual fees and meet minimum capital investment requirements. As of December 31, 2013, the Veladero mine has complied with these requirements with respect to its current mining properties.
Pursuant to federal legislation that implemented law 24.196 in May 1993, and provincial legislation adhering to the same, operating mines are required to pay to the Provincial government a royalty of up to 3% (“Boca Mina”) for minerals extracted from Argentinean soil. This “Boca Mina” is defined as the sales value of the extracted minerals less certain permitted expenses. In addition to the above-mentioned royalty, under the terms of the Exploitation Contract between Barrick and IPEEM, a 0.75% “Boca Mina” royalty is payable to IPEEM for the metals produced from the Veladero property, including production from the Argenta deposit.
Only for the Argenta deposit, an additional royalty equivalent to 1.5% on sales calculated on estimated life-of-pit production, a gold price of $1,500 per ounce and a silver price of $35 per ounce was levied in the first quarter of 2012, payable to a Provincial development trust fund under the terms of the approved EIS.
In June 2011, the Provincial government and mining companies operating in San Juan Province, including MAGSA, signed a responsible mining agreement under which the mining companies agreed not to deduct certain expenses when calculating their 3% Provincial royalty. In October 2011, Barrick and IPEEM agreed to modify the calculation of the 0.75% royalty payable to the IPEEM under the Exploitation Contract using the same criteria, thus effectively changing the royalty calculation to 0.75% of gross sales of doré.

In 2002, as an emergency measure, Argentina adopted a 5% export duty on certain mineral products, including gold. At the time, the duty was described as “temporary.” Veladero’s export of gold doré is still subject to this 5% export duty.
EXISTING INFRASTRUCTURE
Veladero is isolated from major cities and towns and operates on a self-sufficient basis with trucking of material and goods. Due to the remote location, the property is self-sufficient with regard to the infrastructure needed to support the operation. Electric power is generated on site using diesel generators and a wind turbine. The total electric supply is 22 MW. The water supply for industrial usage, i.e., process and dust control is secured from the Rio de las Taguas. The domestic water supply is secured from two water wells. Potable water is treated using reverse osmosis. The Veladero site has four aerobic sewage treatment plants and one prototype sewage treatment plant that utilizes worms instead of bacteria to break down the domestic waste. There are also sewage treatment plants located along the access road at Sepultura and Peñasquito.
Accommodations on site are in a camp that includes emergency medical facilities, cafeteria, gymnasium, offices, and rooms for the Veladero workers.
Other infrastructure includes warehouse, truck shop, maintenance facilities, and analytical laboratory.
HISTORY
The Veladero area was first explored in the late 1980s by Argentine government geologists, who identified scattered gold anomalies in the Veladero Sur area and surrounding region during field examinations of hydrothermal alteration centers identified through satellite imagery. In 1988, administration of mineral rights in the region was transferred from the Federal to the Provincial government, and in 1989 San Juan Province established the IPEEM as the provincial mining entity responsible for holding title to certain of the province’s mineral rights, and for soliciting and administering bids for exploration and mining licences in the province.

Following a competitive bidding process completed by IPEEM in 1994, AGC, a Canadian junior exploration company, was awarded exploration rights to Veladero. AGC then entered into a 60:40 joint venture agreement with Lac Minerals (40%), which was acquired by Barrick a short time later.
In 1995, AGC assigned its interest to its subsidiary, MAGSA, and from 1996 through 1998 the MAGSA/Barrick joint venture successfully explored Veladero. Concurrently, Barrick, through its subsidiary BEASA, explored BEASA’s adjoining 100%-owned Ursulina Sur property as part of the Lama project. In early 1999, Homestake Mining Company (Homestake) acquired AGC. The December 2001 merger of Homestake and Barrick resulted in Barrick gaining 100% indirect control of Veladero through MAGSA and BEASA.
GEOLOGY AND MINERALIZATION
The Veladero deposit is situated at the north end of the El Indio Gold Belt, a 120 km by 25 km north-trending corridor of Permian to late Miocene volcanic and intrusive rocks, which host a number of hydrothermal alteration zones and epithermal mineral deposits. The belt consists of a Tertiary volcanic rift basin in which volcanic flows and tuffs were deposited and subsequently cut by associated intrusions. Basement rocks in the belt consist of andesitic to rhyolitic tuffs, lava flows, and volcaniclastic rocks of the Permo-Triassic Choiyoi Formation, which are overlain unconformably by Tertiary igneous and volcanic rocks ranging in age from older 40 Ma stocks to more recent 4 Ma tuffs, lava flows and volcaniclastic rocks.
The El Indio Gold Belt hosts both high and low sulphidation style mineralization over a 55 km strike length, from the Tambo-El Indio mines in the south to the Pascua-Lama project in the north. Epithermal mineralization within this belt is associated with Tertiary structural trends.
The Veladero deposit is a hypogene-oxidized, high sulphidation gold-silver deposit hosted by volcaniclastic sediments, tuffs, and volcanic breccias related to a Miocene diatreme-dome complex. Hydrothermal alteration is typical of high sulphidation gold deposits, with a silicified core grading outward into advanced argillic alteration, then into peripheral argillic and propylitic alteration haloes. Gold occurs as fine native grains, and is dominantly associated with silicification and with iron oxide or iron sulfate fracture coatings. Silver mineralization is distinct from gold, and occurs as a broader, more diffuse envelope, probably representing a separate mineralizing event.

Technical Report NI 43-101 – March 27, 2014	  	Page 1-8  	

			
	  	www.rpacan.com	

The Veladero deposit forms a broad, disseminated, 400 m to 700 m wide by three kilometre long blanket of mineralization along a N15°W-striking structural trend. The diatreme-dome complex includes a massive, central, brecciated core of heterolithic, matrix-supported tuffisite that transitions outward through clast-supported breccias into the volcanic country rocks. A bedded tuff unit that represents fragments ejected from the central vent forms a ring that overlies portions of the tuffisite and breccias at the southern end of the deposit. The Veladero deposit comprises three main orebodies: Amable in the south, Cuatro Esquinas in the centre, and Filo Federico in the north. The Argenta orebody is a small satellite deposit located approximately five kilometres to the southeast of the Veladero deposit.
The mineralized envelope encompassing greater than 0.2 g/t Au is oriented along a 345°-trending regional structural corridor. The mineralization is dominantly hosted in the diatreme breccias along the fault-bounded northwest trend. Within this trend, higher grade mineralized shoots, averaging approximately 4 g/t Au but with one metre values up to 100 g/t Au, with lengths of 300 m to 500 m, form along northeast striking structural trends and are surrounded by a halo of lower grade mineralization ranging between 0.1 g/t Au and 1.0 g/t Au.
A variety of volcanic explosion breccias and tuffs are the principal host rocks at Cuatro Esquinas and Filo Federico, where alteration consists of intense silicification. The Amable ore body is hosted within bedded pyroclastic breccias and tuffs which are affected by silicification and advanced argillic alteration. Much of the Veladero deposit is covered by approximately 40 m of overburden and the overburden in some areas is up to 170 m thick. The colluvium is generally uncemented.
Precious metal mineralization at Veladero is controlled by stratigraphy, structural trends, and elevation. Gold mineralization can be hosted by any kind of rock at Veladero, including overburden and steam-heat altered lithologies. Principal host rocks are hydrothermal breccias and felsic tuffs at Filo Federico and Cuatro Esquinas, and pyroclastic breccias and felsic to intermediate tuffs at Amable.
EXPLORATION STATUS
The major exploration programs took place prior to the completion of the Feasibility Study in 2002. The original drilling program targeted structural intersections with surface geochemical anomalies (involving rock chip, soil, and screened talus sampling) that were coincident with

Controlled-Source-Audio-Frequency-Magneto-Telluric (CSAMT) resistivity highs and magnetic lows. Since 2002, additional exploration and infill drilling has been completed. More drilling is planned to explore some gaps that still remain on the mining concessions.
MINERAL RESOURCES AND MINERAL RESERVES
The EOY2013 Mineral Resources are summarized in Table 1-1. The Measured and Indicated Mineral Resources total 164.4 million tonnes averaging 0.68 g/t Au and 12.8 g/t Ag and contain 3.6 million ounces of gold and 67.9 million ounces of silver. In addition, the Inferred Mineral Resources total 27.9 million tonnes averaging 0.30 g/t Au and 12.9 g/t Ag and contain 269,000 ounces of gold and 11.6 million ounces of silver. The resources are estimated using a gold price of US$1,500/oz Au. RPA is of the opinion that the Mineral Resources are acceptable, reasonable, and conform to CIM definitions.
The resource estimate gold cut-off grades range from 0.20 g/t for ROM material from the Filo Federico pit Type 1 material to 0.48 g/t for Filo Federico Type 2 material, which requires crushing. The resource model was prepared using all of the drill holes available up to February 2013.
RPA reviewed the resource assumptions, input parameters, geological interpretation, and block modelling procedures and is of the opinion that the Mineral Resource estimate is appropriate for the style of mineralization and that the resource model is reasonable and acceptable to support the EOY2013 Mineral Resource and Mineral Reserve estimates.
The Veladero geology department has developed a very good understanding of the Veladero geology. Geological models were constructed to provide geologic control for grade estimation and to provide parameters for mine planning. Geology models for lithology, alteration, and structural sub-zones were built using Vulcan software. The main faults have also been modelled. Lines and control points based on the exploration drill holes, blast holes, and pit mapping were used in Vulcan to create 3D geological wireframes.
The EOY2013 Mineral Reserve estimate is summarized in Table 1-2. The Proven and Probable Mineral Reserves are estimated to be 186.6 million tonnes at 0.85 g/t Au and 14.8 g/t Ag, containing 5.1 million ounces of gold and 89 million ounces of silver. Over 99% of the open pit reserves are located within the Filo Federico pit of Veladero, with the remainder coming from the Argenta pit. Based on this review, it is RPA’s opinion that the reported material is appropriately classified as Proven and Probable Mineral Reserves in accordance with CIM definitions.

MINING METHOD
The Veladero Mine is a traditional open pit truck/shovel heap leach operation that has been in continuous operation since 2005. Veladero has mined approximately 708 million tonnes of material and produced 5.67 million ounces of gold plus 11.3 million ounces of silver up to the end of 2013.
Mining is planned at an average of approximately 30 Mtpa of Mineral Reserves over the next six years. Waste rock mining varies by year from a high of 63 Mt in 2017 to a low of five million tonnes in the final year of operations, averaging 45 Mtpa. Peak ROM material movement is scheduled at approximately 92 Mtpa (260,000 tpd) in 2017, tapering off to 23 Mt in the final year of operations.
Over 99% of in-situ Mineral Reserves are located within the Filo Federico pit of the Veladero area. Remaining in-situ Mineral Reserves are from the Argenta pit, which is scheduled to be complete in 2014. Historically, mining also took place in the Amable pit, which was depleted in 2013.
MINERAL PROCESSING
Gold is recovered from ore at Veladero using cyanide-heap leaching in a valley-fill leach pad and a Merrill-Crowe zinc cementation gold recovery plant.
The lower gold grade ore, i.e., above the cut-off grade for ROM ore and below the cut-off grade for crushed ore, is mined and trucked to the leach pad. Ore that has a gold grade above the cut-off grade for crushed ore is trucked from the mine or stockpiles and crushed in one of two two-stage crushing circuits to a nominal size of 80% passing (P 80 ) 40 mm. The crushing plant has a capacity of approximately 90,000 tpd, i.e., 60,000 tpd through line one and 30,000 tpd through line two. Haul trucks dump directly into the primary gyratory crushers. After crushing the ore is transferred to a covered stockpile.
After a secondary round of crushing, the ore is conveyed to a 3.7 km long overland conveyor belt for transport to a truck loadout bin that is located adjacent to the processing plant near

Technical Report NI 43-101 – March 27, 2014	  	Page 1-11  	

			
	  	www.rpacan.com	

the heap leach pad. Lime is added to the ore as it is transported on the overland conveyor belt. The ore from the loadout bin is loaded into mine haul trucks for transport to the valley-fill heap leach facility where it is stacked in 15 m lifts.
Approximately 250,000 m 3 of ore is actively under leach at any given time with dilute cyanide leach solution applied using drip emitters. The nominal capacity of the solution pumping system is 2,066 m 3 /h. Pregnant solution is collected by the dam, at the toe of the leach pad, and pumped to the Merrill-Crowe recovery plant.
Gold doré that is produced by the refining process is shipped off-site for further refining to produce fine gold and silver.
ENVIRONMENTAL, PERMITTING AND SOCIAL CONSIDERATIONS
Veladero has an Environmental Management Plan that is certified under the ISO 14001 standards. The plan is audited annually and must be recertified every three years. It is also certified by the International Cyanide Management Code. Veladero was last certified in 2013.
Reports of the monitoring results are submitted to the authorities every six months.
The authorities conduct site inspections at Veladero on a regular basis. Written reports of comments are distributed and Veladero responds to the comments, as required.
The environmental requirements are managed by an on-site staff of professionals and technicians and the legal department in the San Juan office.
The mine closure plan was developed to allow, when practical, closure and rehabilitation activities to be carried out simultaneously with mining activities. This rehabilitation in parallel with mining will allow the performance of certain tasks during the operation of the mine, reducing closure costs and the schedule for completing the tasks at the end of the mine life. Mine closure plans are reviewed and analyzed annually. Current cost estimates for closure at Veladero are approximately US$59 million.

2 INTRODUCTION
Roscoe Postle Associates Inc. (RPA) was retained by Barrick Gold Corporation (Barrick) to prepare an independent Technical Report on the Veladero Gold Mine (the Project) in Argentina. The purpose of this report is to support public disclosure of Mineral Resource and Mineral Reserve estimates at the Project as of December 31, 2013. This Technical Report conforms to NI 43-101 Standards of Disclosure for Mineral Projects. RPA visited the property and the Barrick office in San Juan from February 10 to 14, 2014.
Barrick is a Canadian publicly traded mining company with a large portfolio of operating mines and projects.
Veladero is a large open pit, heap leach gold and silver mine in the high Andes Cordillera of central western Argentina. Operations include open pit mining of gold-silver ore from two mining areas, two-stage crushing, and extraction of precious metals using valley-fill heap leaching and Merrill-Crowe recovery. Since Veladero started production in 2005, the mine has recovered over five million ounces of gold and over eleven million ounces of silver from approximately 204 million tonnes of ore averaging 1.2 g/t Au and 16 g/t Ag.
Mining at Veladero will average approximately 30 Mtpa of ore over the next six years, with mine operations concluding in 2019. Waste rock mining varies by year from a high of 63 Mt in 2017 to a low of 5 Mt in the final year of operations, averaging approximately 45 Mtpa.
There is currently one main open pit mining area referred to as Veladero. Over 99% of in-situ Mineral Reserves are located within the Filo Federico pit of the Veladero area. Remaining in-situ Mineral Reserves are from the Argenta pit, which is scheduled to be depleted in 2014. The Amable pit in the Veladero area was depleted during 2013.
Since 1989, the Instituto Provincial de Exploraciones y Explotaciones Mineras de la Provincia de San Juan (IPEEM) has been the provincial mining entity responsible for holding title to certain of the San Juan Province’s mineral rights, and for soliciting and administering bids for exploration and mining licences in the province. Following a competitive bidding process completed by IPEEM in 1994, Argentina Gold Corp. (AGC), a Canadian junior exploration company, was awarded exploration rights to Veladero. AGC then entered into a

60:40 joint venture agreement with Lac Minerals (40%), which shortly was to become a subsidiary of Barrick. In 1995, AGC assigned its interest to its subsidiary, Minera Argentina Gold S.A. (MAGSA), and from 1996 through 1998 the MAGSA/Barrick joint venture successfully explored the Veladero property. Concurrently, Barrick subsidiary Barrick Exploraciones Argentina S.A. (BEASA) explored the adjoining Ursulina Sur property as part of the Lama project. In early 1999, Homestake Mining (Homestake) acquired AGC. The December 2001 merger of Homestake and Barrick resulted in Barrick’s gaining 100% indirect control of Veladero through MAGSA and BEASA.
The Veladero mine comprises the following mining properties: (i) the Veladero mining group, consisting of eight mining concessions owned by IPEEM and operated by MAGSA, pursuant to applicable provincial law and the Exploitation Contract between IPEEM and MAGSA (as amended) and (ii) the Filo Norte mining group, consisting of five mining concessions owned by MAGSA, which are: Ursulina Sur, Florencia 1, Gaby M, Río 2, and Río 3. The Veladero mining properties cover an area of approximately 14,420 hectares.
Pursuant to the Argentina Mining Code, mining concessions do not have an expiry date, however, to keep them in good standing concession holders are required to pay certain annual fees and meet minimum capital investment requirements. As of December 31, 2013, the Veladero mine has complied with these requirements with respect to its current mining properties.
Barrick has an undivided 90% interest in “Campo Las Taguas”, which encompasses the surface property affected by Veladero’s mining facilities. With respect to the 10% interest of “Campos Las Taguas” owned by third parties, Barrick and IPEEM have obtained all necessary easements for access over surface property. Certain other mine related facilities are located in Campo Colangui, which is also owned by Barrick. The Argenta pit is also located at the Campo Las Taguas. Sufficient surface rights have been obtained for current operations at the property.
Pursuant to federal legislation that implemented law 24.196 in May 1993, and provincial legislation adhering to the same, operating mines are required to pay to the Provincial government a royalty of up to 3% (“Boca Mina”) for minerals extracted from Argentinean soil. This “Boca Mina” is defined as the sales value of the extracted minerals less certain permitted expenses. In addition to the above-mentioned royalty, under the terms of the

	  	www.rpacan.com	

Exploitation Contract between Barrick and IPEEM, a 0.75% “Boca Mina” royalty is payable to IPEEM for the metals produced from the Veladero property, including production from the Argenta deposit.
Only for the Argenta deposit, an additional royalty equivalent to 1.5% on sales calculated on estimated life-of-pit production, a gold price of $1,500 per ounce and a sliver price of $35 per ounce was levied in the first quarter of 2012, payable to a Provincial development trust fund under the terms of the approved EIS.
In June 2011, the Provincial government and mining companies operating in San Juan Province, including MAGSA, signed a responsible mining agreement under which the mining companies agreed not to deduct certain expenses when calculating their 3% Provincial royalty. In October 2011, Barrick and IPEEM agreed to modify the calculation of the 0.75% royalty payable to the IPEEM under the Exploitation Contract using the same criteria, thus effectively changing the royalty calculation to 0.75% of gross sales of doré.
In 2002, as an emergency measure, Argentina adopted a 5% export duty on certain mineral products, including gold. At the time, the duty was described as “temporary.” Veladero’s export of gold doré is still subject to this 5% export duty.

4 PROPERTY DESCRIPTION AND LOCATION
LOCATION
The Veladero Mine is located on the east flank of the Andes Cordillera, six kilometres east of the Chile/Argentina border. The mine site is at approximately 29°22’ South latitude and 69°57’ West longitude in the Department of Iglesia, San Juan Province, northwest Argentina. The closest major population and commercial center is the provincial capital of San Juan, which is approximately 280 km southeast of Veladero. By road the distance is approximately 360 km via paved National Highway No. 40 north from San Juan to Provincial Road No. 436 (paved) and the village of Pismanta, and by public gravel road to Tudcum. Barrick’s 156 km all-weather gravel road continues from Tudcum over Conconta Pass, through the Valle del Cura, and over Despoblados Pass to Veladero. Elevations at the mine range from 3,900 m to 4,800 m. The mine location is shown in Figure 4-1.
LAND TENURE
Since 1989, IPEEM has been the provincial mining entity responsible for holding title to certain of the San Juan Province’s mineral rights, and for soliciting and administering bids for exploration and mining licences in the province. Therefore, some of the mining licences are held by IPEEM. The remainder of the mining licences are held by MAGSA, which is a wholly-owned subsidiary of Barrick. RPA notes that BEASA controls an extensive land package in the district that is contiguous with the mine concessions. This report summarizes only the mining and surface rights that are directly related to the Veladero Mine.
The Veladero mine comprises the following mining properties: (i) the Veladero mining group, consisting of eight mining concessions owned by IPEEM and operated by MAGSA, pursuant to applicable provincial law and the Exploitation Contract between IPEEM and MAGSA (as amended) and (ii) the Filo Norte mining group, consisting of five mining concessions owned by MAGSA, which are: Ursulina Sur, Florencia 1, Gaby M, Río 2, and Río 3. The Veladero mining properties cover an area of approximately 14,420 hectares.
The ownership details of the mining properties are shown in Table 4-1. Access rights to the mine and surface rights for supporting facilities are secured through easements. Details of these land holdings are provided in Table 4-2. The land holdings are shown in Figure 4-2.

Pursuant to federal legislation which implemented law 24.196 in May 1993, and provincial legislation adhering to the same, operating mines are required to pay to the Provincial government a royalty of up to 3% (“Boca Mina”) for minerals extracted from Argentinean soil. This “Boca Mina” is defined as the sales value of the extracted minerals less certain permitted expenses. In addition to the above-mentioned royalty, under the terms of the Exploitation Contract between Barrick and IPEEM, a 0.75% “Boca Mina” royalty is payable to IPEEM for the metals produced from the Veladero property, including production from the Argenta deposit.
Finally, and only for the Argenta deposit, an additional royalty equivalent to 1.5% on sales calculated on estimated life-of-pit production, a gold price of $1,500 per ounce and a sliver price of $35 per ounce was levied in the first quarter of 2012, payable to a Provincial development trust fund under the terms of the approved EIS.
In September 2013, Argentina adopted a new 10% tax on dividends paid by Argentine entities to individuals and non-resident investors. Barrick believes that this withholding tax is not applicable to dividends to be paid by the Veladero mine as a result of an existing tax stability arrangement.
In October 2011, the Argentinean government issued Decree 1722, which requires crude oil, natural gas, and mining companies to repatriate and convert all foreign currency revenues resulting from export transactions into Argentine pesos. A bank transaction tax of 0.6% applies to both the initial conversion of foreign currency revenues into pesos and the subsequent conversion of pesos to foreign currencies.
In June 2011, the Provincial government and mining companies operating in San Juan Province, including MAGSA, signed a responsible mining agreement under which the mining companies agreed not to deduct certain expenses when calculating their 3% Provincial royalty. In October 2011, Barrick and IPEEM agreed to modify the calculation of the 0.75% royalty payable to the IPEEM under the Exploitation Contract using the same criteria, thus effectively changing the royalty calculation to 0.75% of gross sales of doré.

In 2002, as an emergency measure, Argentina adopted a 5% export duty on certain mineral products, including gold. At the time, the duty was described as “temporary.” Veladero’s export of gold doré is still subject to this 5% export duty.
Barrick has acquired all of the permits necessary to operate the Veladero mine. However, in March 2013, as a result of an administrative investigation, the Ministry of Mines in the Province of San Juan issued a permit amendment restricting the amount of fresh water that can be used at the Project’s heap leach pad. Barrick expects the restrictions to be removed shortly, however, failure to obtain approvals in a timely manner will have an increasing impact on 2014 production. In RPA’s opinion, it is reasonable to assume that the current situation will be resolved in a timely manner, thus not impacting the current Mineral Resource and Mineral Reserve estimates.
RPA is not aware of any significant environmental liabilities on the property or significant factors and risks that could affect access, title, or the ability to operate the Veladero mine.

5 ACCESSIBILITY, CLIMATE, LOCAL RESOURCES, INFRASTRUCTURE AND PHYSIOGRAPHY
ACCESSIBILITY
The closest major population and commercial center is the provincial capital of San Juan, approximately 280 km southeast of Veladero. By road, the distance is approximately 360 km, via paved National Highway No.40 north from San Juan to Provincial Road No.436 (paved) and the village of Pismanta, and by public gravel road to Tudcum. Barrick’s 156 km all-weather gravel road continues from Tudcum over Conconta Pass, through the Valle del Cura, and over Despoblados Pass to Veladero.
It takes approximately six hours to drive to Veladero from San Juan, which in turn is approximately a two hour drive to the International airport at Mendoza. There are regular flights to Mendoza from Santiago, Chile and there are also direct flights to San Juan from Buenos Aires, Argentina.
LOCAL RESOURCES
Veladero is isolated from major cities and towns and operates on a self-sufficient basis with material and goods trucked to the site. Mine personnel work on a residential rotation. Operations personnel work a 14 day on – 14 day off rotation on 12-hour shifts. Administrative personnel work either a four day on - three day off schedule or an eight day on - six day off schedule. The mine operates year round.
INFRASTRUCTURE
Due to the remote location, the property is self-sufficient with regard to the infrastructure needed to support the operation. Electric power is generated on site using diesel generators and a wind turbine. The water supply for industrial usage, i.e. process and dust control is secured from the Rio de las Taguas. The domestic water supply is secured from two water wells. The potable water is treated using reverse osmosis. The Veladero site has four aerobic sewage treatment plants and one prototype sewage treatment plant that utilizes worms instead of bacteria to break down the domestic waste. There are also sewage treatment plants located along the access road at Sepultura and Peñasquito.

Accommodations on site are in a camp that includes emergency medical facilities, cafeteria, gymnasium, offices, and rooms for the Veladero workers.
Other infrastructure includes warehouse, truck shop, maintenance facilities, and analytical laboratory.
PHYSIOGRAPHY
The Veladero Mine area is characterized by rugged mountains with deeply incised steep-sided valleys. Elevations at the mine range from 3,900 MASL to 4,800 MASL, and the alpine climate is cold, dry, and windy. Vegetation is sparse, and is concentrated in wetlands areas. Rock outcrops and colluvial soils predominate on slopes, and overburden thicknesses of up to 170 m occur in the mine area.
Highest annual temperatures occur from December through February, when maximum daytime temperatures generally range from 10ºC to 22ºC, with lows between -5ºC and 5ºC. Winter months from June through August have daytime highs generally between -10ºC and 10ºC, and night time lows of -10ºC to -30ºC. Mean annual precipitation is estimated to be approximately 200 mm at 4,400 m elevation, with most of the precipitation arriving as snow. Winter conditions can be severe, with intense winds, blowing snow, extreme cold, and can adversely affect mine access and operations. Rocks and gravel airborne by strong gusty winds are a common hazard in mine operations and on access roads. Local weather conditions are monitored by five meteorological stations across the site.
The mine is in the Rio de las Taguas watershed, with Despoblados, Potrerillos, Guanaco Zonzo, and Canito creeks comprising the other major perennial streams in the mine area. Water supplies for Veladero are extracted from surface and groundwater sources in the Rio de las Taguas valley.
There is no permanent habitation in the area. Tudcum is the nearest village.

6 HISTORY
The Veladero area was first explored in the late 1980s by Argentine government geologists, who identified scattered gold anomalies in the Veladero Sur area and surrounding region during field examinations of hydrothermal alteration centers identified through satellite imagery. In 1988, administration of mineral rights in the region was transferred from the Federal to the Provincial government, and in 1989 San Juan Province established the IPEEM as the provincial mining entity responsible for holding title to certain of the Province’s mineral rights, and for soliciting and administering bids for exploration and mining licences in the Province.
Following a competitive bidding process completed by IPEEM in 1994, AGC, a Canadian junior exploration company, was awarded exploration rights to Veladero. AGC then entered into a 60:40 joint venture agreement with Lac Minerals (40%), which was acquired by Barrick a short time later.
In 1995, AGC assigned its interest to its subsidiary, MAGSA, and from 1996 through 1998 the MAGSA/Barrick joint venture successfully explored Veladero. Concurrently, Barrick, through its subsidiary BEASA, explored BEASA’s adjoining 100%-owned Ursulina Sur property as part of the Lama project. In early 1999, Homestake Mining acquired AGC, and intensified Veladero exploration, while Barrick advanced definition of the Filo Norte or Federico deposit on the Ursulina Sur property. The December 2001 merger of Homestake and Barrick resulted in Barrick gaining 100% indirect control of Veladero through MAGSA and BEASA.
Exploration by the Veladero joint venture initially focused on the Veladero Sur gold anomalies, but eventually moved north and encountered strongly anomalous gold mineralization associated with outcropping breccia bodies in the area of what is now the Amable deposit. Initial RC drilling in late 1995 defined a small resource in this zone (Brecha Agostina), and focused the joint venture’s exploration efforts on other breccia exposures on the property.
Since Veladero started production in 2005, the mine has produced over five million ounces of gold and over eleven million ounces of silver from approximately 204 million tonnes of ore averaging 1.2 g/t Au and 16 g/t Ag. The production history details are described in Section 16.

7 GEOLOGICAL SETTING AND MINERALIZATION
REGIONAL GEOLOGY
The Veladero deposit is situated at the north end of the El Indio Gold Belt, a 120 km by 25 km north-trending corridor of Permian to late Miocene volcanic and intrusive rocks, which host a number of hydrothermal alteration zones and epithermal mineral deposits (Figure 7-1). The belt consists of a Tertiary volcanic rift basin in which volcanic flows and tuffs were deposited and subsequently cut by associated intrusions. Basement rocks in the belt consist of andesitic to rhyolitic tuffs, lava flows, and volcaniclastic rocks of the Permo-Triassic Choiyoi Formation, which are overlain unconformably by Tertiary igneous and volcanic rocks ranging in age from older 40 Ma stocks to more recent 4 Ma tuffs, lava flows and volcaniclastic rocks. These volcanic rocks within the basin are grouped into five units, which from youngest to oldest are the Vallecito (5 Ma to 7 Ma), Vacas Heladas (9 Ma to 13 Ma), Cerro de las Tortolas (12 Ma to 19 Ma), Escabrosa (17 Ma to 21 Ma), and Tilito (21 Ma to 27 Ma). All of these units consist of felsic and intermediate-to-mafic volcanic rocks derived from volcanic centers located both within and outside of the mineralized belt.
The regional structural setting of the El Indio Gold Belt is dominated by fault and fracture sets associated with Tertiary east-west regional compression. The main fault set is a series of north-south striking reverse faults with associated east-west extensional fracture sets and 030º to 060º and 320º to 300º conjugate shear sets. Intrusive and volcanic centers are concentrated at structural intersections. The north-south reverse faults border the volcanic rift basin. These structural trends are important to the localization of mineralization at Veladero and at other deposits associated with the belt, including the El Indio, Pascua-Lama and Zancarron deposits.
The El Indio Gold Belt hosts both high and low sulphidation style mineralization over a 55 km strike length, from the Tambo-El Indio mines in the south to the Pascua-Lama project in the north. Epithermal mineralization within this belt is associated with Tertiary structural trends.

LOCAL AND PROPERTY GEOLOGY
The Veladero deposit is a hypogene-oxidized, high sulphidation gold-silver deposit hosted by volcaniclastic sediments, tuffs, and volcanic breccias related to a Miocene diatreme-dome complex. Hydrothermal alteration is typical of high sulphidation gold deposits, with a silicified core grading outward into advanced argillic alteration, then into peripheral argillic and propylitic alteration haloes. Gold occurs as fine native grains, and is dominantly associated with silicification and with iron oxide or iron sulfate fracture coatings. Silver mineralization is distinct from gold, and occurs as a broader, more diffuse envelope, probably representing a separate mineralizing event. Copper and other base metals are insignificant, and sulfide mineralization is negligible. Principal controls on gold mineralization are structures, brecciation, alteration, host rocks, and elevation.
The Veladero deposit forms a broad, disseminated, three kilometre long blanket of mineralization along a N15ºW-striking structural trend. The diatreme-dome complex includes a massive, central, brecciated core of heterolithic, matrix-supported tuffisite that transitions outward through clast-supported breccias into the volcanic country rocks. A bedded tuff unit that represents fragments ejected from the central vent forms a ring that overlies portions of the tuffisite and breccias at the southern end of the deposit. The Veladero deposit comprises three main ore bodies: Amable in the south; Cuatro Esquinas in the center; and Filo Federico in the north. The Argenta ore body is a small satellite deposit located approximately five kilometres to the southeast of the Veladero deposit.
A variety of volcanic explosion breccias and tuffs are the principal host rocks at Cuatro Esquinas and Filo Federico, where alteration consists of intense silicification. The Amable ore body is hosted within bedded pyroclastic breccias and tuffs which are affected by silicification and advanced argillic alteration. Much of the Veladero deposit is covered by approximately 40 m of overburden and the overburden in some areas is up to 170 m thick. The colluvium is generally uncemented.
The water table at Veladero is deep, and is below the projected pit bottom elevation. There is also no known significant groundwater within the colluvial cover. The simplified lithology in the deposit area is shown in Figure 7-2.

ALTERATION
The alteration assemblage is typical of high sulphidation deposits with a silica core grading outward into silica/alunite and then argillic alteration. The gold mineralization is dominantly associated with the silicified core, which is composed of silica, hematite, goethite and jarosite. Minor sulphide mineralization is present at less than one percent concentrations.
There are three main sectors, Amable in the south, Cuatro Esquinas in the centre, and Filo Federico to the north. The more recently discovered Argenta ore body represents a separate satellite sector located approximately five kilometres to the southeast of Amable. A variety of volcanic explosion breccias and tuffs are the principal host rocks at Federico and Cuatro Esquinas where alteration consists of intense silicification. Amable is hosted within bedded pyroclastic breccias and tuffs which are affected by both silicification and advanced argillic alteration. The intense silicification may be vuggy to massive. The surrounding country rocks are normally composed of argillically or propylitically altered intermediate volcanic flows, domes and volcaniclastic sediments.
A late-stage, silica-destructive event produced an intensely steam heated unit, concentrated around the main northwest-striking faults. This unit is highly altered and has very low rock strength.
The simplified alteration distribution in the deposit area is shown in Figure 7-3.

MINERALIZATION
Precious metals mineralization at Veladero is controlled by stratigraphy, structural trends and elevation. Disseminated gold mineralization forms a 400 m to 700 m wide by three kilometre long tabular blanket localized between the 3,950 m and 4,400 m elevations. Veladero has been separated into three main sectors, Amable in the south, Cuatro Esquinas in the centre and Filo Federico to the north (Figure 7-4). All sectors of the deposit are characterized by the same high sulphidation style of mineralization.
The mineralized envelope encompassing greater than 0.2 g/t Au is oriented along a 345°-trending regional structural corridor. The mineralization is dominantly hosted in the diatreme breccias along the fault-bounded northwest trend. Within this trend, higher grade mineralized shoots, averaging approximately 4 g/t Au but with one metre values up to 100 g/t, with lengths of 300 m to 500 m, form along northeast striking structural trends and are surrounded by a halo of lower grade mineralization ranging between 0.1 g/t Au and 1.0 g/t Au.
A mostly barren zone approximately 300 m long occurs between Amable and Cuatro Esquinas. From Cuatro Esquinas north through Filo Federico, the gold mineralization envelope is continuous. The Veladero ore envelope lacks recognized roots or high-grade feeder conduits at depth, and exhibits no evidence for significant supergene enrichment of metals (Barrick, 2005).

Gold mineralization can be hosted by any kind of rock at Veladero, including overburden and steam-heat altered lithologies. Principal host rocks are hydrothermal breccias and felsic tuffs at Filo Federico and Cuatro Esquinas, and pyroclastic breccias and felsic to intermediate tuffs at Amable. Main-stage introduction of gold clearly is younger than diatreme eruption, acid leaching, and major stages of silicification and fracturing. It accompanied or closely followed hypogene deposition of iron oxides and jarosite. Principal controls on localization of gold mineralization are structurally-induced open spaces (fracture zones, structural intersections), favourable host rocks, brecciation, alteration, and elevation.
Gold occurs at Veladero as minute native grains disseminated along fracture surfaces, and usually it is associated with silicification and hematite, goethite, or jarosite. Trace gold telluride minerals have been identified petrographically, but are not significant. Gold grains have been found encapsulated by quartz overgrowths, and also by jarosite. Megascopic gold grains up to one millimetre in size have been recovered from a number of drill holes, but most Veladero gold is less than 50 microns in size. Metallographic studies indicate that the gold contains some silver and that the overall gold purity or millesimal fineness is approximately 800 to 900.
Amable and Cuatro Esquinas contain zones in which gold has been found disseminated and encapsulated within silica or remnant sulphides at grain sizes of 5 microns or less. Contrastingly, the gold mineralization in Filo Federico and Filo Mario consists mainly of gold grains located primarily on particle surfaces or fracture planes, possibly suggesting gold emplacement in two separate events (SNCL, 2002).

Silver values are consistently anomalous at Veladero. The principal silver-bearing mineral is acanthite (silver sulfide). In addition, grains of native silver, silver chloride, and a silver-bearing telluride have been identified in thin sections. Within the ore zone, silver and gold exhibit different distributions: some silver mineralization correlates with gold (Ag:Au ratios generally less 20:1); some silver has no associated gold; and some gold has little to no associated silver. These observations of silver and gold distributions suggest multiple events of precious metals mineralization (Barrick, 2005).
Silver is present as sub five micron size mineralization most typically as silver sulfide, silver chloride (cerargyrite), and native silver with all forms present with varying levels of silica encapsulation.
Goethite, hematite, and jarosite are the dominant gangue minerals in the Veladero ore bodies, occurring as earthy to crystalline fracture coatings, vug linings, breccia matrices, and disseminations. Jarosite is more abundant in the Amable sector, while hematite and goethite predominate at Filo Federico.
Sulphide mineralization within the deposit is negligible, with overall abundances of less than one percent. Pyrite is the most common sulphide mineral, and locally may reach three percent. Where present, it occurs as fine disseminations encapsulated by or intergrown with quartz, and is not known to be associated with gold. Other metallic sulphides identified in thin sections are chalcopyrite, sphalerite, bornite, pyrrhotite, arsenopyrite, cinnabar, and molybdenite; all are volumetrically insignificant.
Trace element analytical results are available from five metre downhole sample composites from 109 drill holes distributed across the Amable, Cuatro Esquinas, and Filo Federico sectors (Table 7-2). Of the nine elements analyzed, mercury is the most anomalous, followed by arsenic. Trace element geochemistry shows broad, strongly anomalous concentrations of arsenic, antimony, bismuth and lead in the Amable sector. Mercury is anomalous throughout the property, with highest concentrations at Filo Federico, where mercury exceeds 10 ppm over broad areas. In this sector mercury shows a strong correlation with a strongly silicified felsic tuff unit (Barrick, 2005).

8 DEPOSIT TYPES
The Veladero deposit is a high sulphidation epithermal gold-silver deposit hosted by volcaniclastic sediments, tuffs, and volcanic breccias related to a Miocene diatreme-dome complex. Hydrothermal alteration is typical of high sulphidation gold deposits, with a silicified core grading outward into advanced argillic alteration, then into peripheral argillic and propylitic alteration haloes. Gold occurs as fine native grains, and is dominantly associated with silicification and with iron oxide or iron sulfate fracture coatings. Silver mineralization is distinct from gold, and occurs as a broader, more diffuse envelope, probably representing a separate mineralizing event. Copper and other base metals are insignificant, and sulphide mineralization is negligible. Principal controls on gold mineralization are structures, brecciation, alteration, host rocks, and elevation (Barrick, 2005).

9 EXPLORATION
The major exploration programs took place prior to the completion of the Feasibility Study in 2002. The original drilling program targeted structural intersections with surface geochemical anomalies (involving rock chip, soil, and screened talus sampling) that were coincident with Controlled-Source-Audio-Frequency-Magneto-Telluric (CSAMT) resistivity highs and magnetic lows. Since 2002, additional exploration and infill drilling has been completed. More drilling is planned to explore some gaps that still remain on the mining concessions. The historical drilling from 1995 to 2013 is discussed under Section 10 Drilling.

10 DRILLING
The resource model is based on data available up to February 2013. This includes 1,279 drill holes totalling 329,213 m and 490 underground chip-face and wall traverse samples totalling 4,145 m (Table 10-1). Over 95% of the drilling and chip samples summarized in Table 10-1 have gold and silver assays available. A drill hole plan is provided in Figure 10-1. Examples of drill cross sections are provided in Section 14.
Over 80% of the drilling was by reverse circulation (RC) and the balance was diamond drill holes (DDH). Approximately 28 DDHs totalling 5,675 m were drilled from an underground exploration drift in 2002 and 2003. Most of the surface diamond drill holes and RC holes were drilled at steeply inclined orientations toward the west or the southeast.
RC holes were drilled using 5  1 ⁄ 4 in. to 6 in. tricone bits, and all diamond drill holes were collared using HQ, HQ2, or HQ3 size tools. Some core holes were reduced to NQ diameter when conditions warranted. Many of the deeper diamond drill holes incorporated RC pre-collars, especially in areas of thick overburden. Hole lengths ranged from 20 m to 601 m. The abundance of intense silicification and fractured/brecciated ground at Veladero resulted in slow drilling progress, low bit life, and high per-metre drill costs. Core drilling averaged only 17 m advance per 24-hour day, and RC progress averaged approximately 52 m per day.
Drill hole spacing varies across the deposit. In the central portions of the Amable and Filo Federico pits average drill hole spacing is in the range of 35 m to 40 m, increasing outwards to 50 m to 90 m spacing, and increasing to approximately 100 m to 120 m spacing toward the peripheries of the orebodies. Condemnation holes outside mineralized areas are drilled on approximately 400 m centres to sterilize waste dump areas and other infrastructure sites.

CORE AND RC RECOVERY
Core recovery historically averages 81% and approximately 60% of the samples have core recoveries exceeding 80%. RC recovery historically averages 70% and only approximately 35% of the samples have recoveries exceeding 80%. The core and RC recovery rates are not very good but can be attributed to the large volumes of fractured, brecciated, and broken rock that hosts the mineralization at Veladero.
POSSIBLE DRILL HOLE SAMPLING BIASES
Over approximately 80% of the drill hole sampling is from RC holes. A study that compared RC grades and diamond drill hole grades found that, in general, the core samples had lower grades than adjacent RC samples (Resource Evaluation Inc., 2003). The discrepancy was attributed to the ability of the significantly larger RC samples to recover more of the fine size fraction, which contains most of the gold, than core samples, particularly in highly fractured and vuggy material, which tends to host the higher gold grades.
Sanfurgo (2004) found that the RC gold and silver grades decreased at lower RC sample recoveries at Amable and to a lesser degree at Filo Federico. Screen tests have found that most of the gold is contained in the fine fractions and that there is a direct relationship between gold grades and fracture intensity. The results suggested that the RC gold and silver grades might be understated at Amable and Filo Federico.
RPA concludes that there is a possibility that both the core and RC gold and silver grades may be biased low, however, RPA previously found that no significant sampling biases were evident based on the production reconciliation results for the first nine months of 2011. The significantly positive production reconciliation results for 2013 have been attributed mostly to new high grade mineralized structures defined by the blast holes that were generally not intersected in the exploration drill holes. This sampling bias may also play a contributing role.

11 SAMPLE PREPARATION, ANALYSES AND SECURITY
SAMPLING METHOD AND APPROACH
Samples from the initial 56 RC holes (6,734 m of drilling) were collected on two metre or longer intervals. All subsequent RC drilling was sampled on one metre intervals. Most of the RC samples were drilled dry. Wet sampling was conducted only when groundwater was encountered or when water injection was necessary to avoid sticking the rods. A double cyclone system was used to capture as many fines as possible from RC holes. The exhaust from the first cyclone circulated to a second cyclone to collect the fines, which were then included with all chips recovered from the sample run.
Drill core was sampled on nominal one metre intervals, depending on geologic conditions. The maximum length for individual samples from drill core is two metres. Core was cut in half using a water-cooled diamond saw; half was bagged and submitted for assay, and half was retained for reference or for metallurgical sampling.
The 509 m long Amable decline and the 638 m long Filo Federico decline generated 5,150 m of chip samples from the workings, mostly from one metre long horizontal cuts from each rib and face, taken with a pneumatic chipping hammer. Muck piles from every round of decline advance were grab-sampled, generating 7,181 individual samples. The muck samples were not used for the resource estimate.
Blast hole samples are taken with a shovel from channels cut on both sides of the blast hole cuttings pile after the over-drill material is scraped off. Approximately 12 kg of blast hole material is sent to the mine laboratory. The drills do not have skirts but loss of fines during strong winds is not a significant issue because the drills use some water, which holds the cuttings together in a semi-frozen state. The blast hole data are not used for the resource model, except to periodically update the gold grade envelope and geology wireframes.
RPA is of the opinion that the core, RC, underground chip, and blast hole sampling procedures at Veladero are reasonable.

SAMPLE PREPARATION, ANALYSES AND SECURITY
Prior to January 2000, drill sample preparation and assaying was performed by Centro de Investigacion Minera y Metalurgica (CIMM), an independent commercial laboratory based in Santiago, Chile. The entire RC drill sample was collected and split at the drill site to an 8 kg to 10 kg sub-sample, which was delivered to a portable preparation facility at the Veladero camp. Samples were dried at 50°C, jaw-crushed to approximately 5 mm, then roll-crushed to -10 mesh. RC sample rejects are stored at Veladero. The portable facility could not consistently meet the preparation protocol of 100% -2 mm so it was discontinued after the first 3,175 drill samples. All subsequent samples were sent to CIMM’s preparation facility in San Juan. At this location the 8 kg to 10 kg RC samples were crushed to 100% passing -2 mm and split to 1.0 kg, then pulverized in a single-pass LM-2 ring and puck mill to 95% -150 mesh. Pulps were then split to 250 g and sent to CIMM’s laboratory for assay. The 750 g pulp reject was returned to MAGSA for storage.
Beginning in January 2000 Bondar-Clegg in Coquimbo, Chile (and its successor company, ALS Chemex) was contracted as the primary laboratory to replace CIMM, and subsequent RC, core, and rock chip samples were prepared at an on-site facility. The entire RC sample interval (or half core for diamond drill hole samples) was delivered to the preparation laboratory for weighing, drying at 60°C, and splitting to 8 kg to 10 kg representing approximately 25% of original RC sample weights. The coarse rejects were stored at Veladero, and the 25% splits were Rhino-crushed to 90% -10 mesh, then split again to obtain a 1.0 kg sample. This sample was sent to Mendoza for oven-drying at 60°C, followed by pulverizing to 95% -150 mesh, and riffle-splitting to a 250 g pulp for assay. In 2010, Acme Analytical Laboratories S.A. (Acme) in Santiago, Chile, was selected as the primary assay laboratory. Since 2012, SGS has prepared samples at its on-site sample preparation facility and the samples have been analyzed at the SGS laboratory in San Juan.
The drill core, field duplicates, and reject material are stored at very well organized and secure locations on site and in San Juan. The 250 g pulps are placed in small plastic screw-top containers and stored in 45 gal drums.
Veladero’s standard assay protocol for drill samples and rock chips involves initial assaying for gold by fire assay fusion of a 50 g pulp and analysis by atomic absorption (AA). Results are reported in ppm, with a lower detection limit of 0.005 ppm Au. For silver, 4-acid (“total”) digestion of a 1 g pulp is accomplished, followed by AA analysis. Results are reported in ppm, with a lower detection limit of 0.10 ppm Ag.

Technical Report NI 43-101 – March 27, 2014	  	Page 11-2  	

			
	  	www.rpacan.com	

Any samples reporting initial results greater than 3 ppm Au or 50 ppm Ag are re-analyzed for the overlimit element using 50 g fire assay fusion and a gravimetric finish. The detection limits for gravimetric fire assays are 0.1 ppm for gold and 0.35 ppm for silver.
Ten-element geochemical analyses are made of composited drill samples, with 10 g of sample pulp composited from each of five one-metre drill samples. The pulp composite is homogenized and then analyzed for Cu, Pb, Zn, Cd, Mn, and Mo by ICP methods. Mercury is determined by cold-vapor analysis, and As, Bi, and Sb are determined by hydride generation.
Through 2003, drill samples grading greater than 0.4 ppm Au had six-hour cyanide solubility shake tests for gold and silver performed on a 20 g split of the sample pulp.
Analytical results are received from the laboratory in an electronic format and are entered directly into the acQuire database without external manipulations.
CIMM, acquired by SGS in 2012, and Bondar-Clegg (ALS Chemex) have been the project’s principal analytical laboratories. Miscellaneous analytical work and check assays on drill samples have been performed by other laboratories including Alex Stewart, ALS Chemex/Geolab, Geoanalítica, Lakefield, McClelland, and Verilab. Since 2012, the samples have been analyzed at the SGS laboratory in San Juan. SGS and ALS are very large international companies with accredited laboratories worldwide.
Rock chip and drill samples are delivered by MAGSA personnel to the on-site sample preparation facilities where SGS assumes sample custody.
The blast hole samples are prepared and assayed at the Veladero mine laboratory, which is a clean, modern, and well-equipped laboratory with a Laboratory Information Management System (LIMS) and good internal QA/QC and reporting procedures. The blast hole samples are crushed to 90% -10 mesh and pulverized to 95% -200 mesh. The samples are analyzed for gold by fire assay fusion of a 40 g pulp and analysis by AA. For silver, four-acid (“total”) digestion of a 1 g pulp is accomplished, followed by AA analysis. Any samples reporting initial results greater than 4 ppm Au or 100 ppm Ag are re-analyzed for the overlimit element using a gravimetric finish.

RPA is of the opinion that the sample preparation, analytical protocols, and security measures are very good and exceed industry standard practice.
QUALITY ASSURANCE AND QUALITY CONTROL
Veladero’s quality control (QC) and quality assurance (QA) procedures were designed in 1998 by consultant Dr. Barry Smee, and utilizes field blanks to monitor contamination; pulp standards to monitor accuracy; plus field duplicates, preparation duplicates and pulp duplicates to monitor precision. Quality control samples are included with sample submittals from RC chips, drill core, and underground chip sampling.
Blanks consist of crushed barren material, and are inserted every fortieth sample. If assay results for a blank sample show anomalous gold or silver, the lab re-assays all samples for the batch containing that blank. One in 30 samples is a duplicate, which is inserted at varied frequency so that it is blind to the laboratory. If duplicate results do not agree within acceptable limits (usually ±20%), all samples in that batch are re-run.
Six internal reference standard pulps prepared from Veladero material cover a range of grades and are used to monitor laboratory accuracy. As with duplicates, if the laboratory’s result for a standard falls outside of established control limits, all samples from that batch are re-assayed. Standard pulps are submitted at a frequency of one in every 30 samples.
One in every twenty crushed samples are checked for granulometry to assure 90% passing 10 mesh, and one in 20 pulps are also is checked to meet the standard of 95% passing 150 mesh.
Ten percent of all samples analyzed at the primary laboratory (Bondar-Clegg/ALS Chemex) are re-assayed at a second laboratory during or following a drill campaign, as an independent check on accuracy of the primary laboratory.
In 2006, Barrick began implementation of standardized QA/QC procedures worldwide for exploration and production samples, which included the regular insertion of in-house

			
Barrick Gold Corporation – Veladero Mine, Project #2254
Technical Report NI 43-101 – March 27, 2014	  	Page 11-4  	

			
	  	www.rpacan.com	

standards, blanks, field duplicates, reject duplicates, and pulp replicates. Target insertion rates are approximately five percent for standards, two percent for blanks, and five percent for a combination of field, reject, and pulp duplicates. In addition, approximately five percent of the pulps are sent to external laboratories and sieve tests are also carried out on a regular basis. The current insertion rates at Veladero for exploration samples are approximately four percent each for standards, blanks, and duplicates, and five percent for external check assays. The current insertion rate for blast hole samples is one standard, one blank, and two duplicates (field, reject, and pulp) in each batch of 30 samples.
A detailed quality control report is prepared at least annually, or after each major sampling program is completed. This report includes control charts and discussions of QC results for the current reporting period.
Barry Smee completed annual QA/QC audits of Veladero’s sampling and assaying from 1998 through 2002. During 2003 the Veladero database was reviewed in conjunction with resource and reserve audits completed by Resource Evaluation Inc. and by Micon International Ltd., respectively.
The overall sampling and analytical precision for the exploration samples is approximately 10% at the 0.5 g/t Au concentration (Smee, 2001 and 2002). This is very good for a gold deposit and suggests that most of the gold is very fine grained and homogeneously distributed. The standards and external check assay data reveal no significant analytical biases for the resource related samples.
The Veladero mine laboratory has been in operation since November 2004. All of the blast hole samples are assayed at the mine laboratory, which has its own QA/QC program. A review of the laboratory by Lynda Bloom of Analytical Solutions Ltd. (ASL) in June 2005 found that it was a well-designed facility with sample preparation, analytical and QC procedures properly implemented (ASL, 2005). Procedures were well-documented and were standard industry practice for gold analyses. The highlights of the laboratory review included:
 
 	1.	A LIMS that provides state-of-the-art information control.	
 
 	2.	Bar-coding for samples to improve tracking and minimize sample mix-ups.	
 
 	3.	A strong emphasis on assay QC.	
 
 	4.	The laboratory scored 93% on the ASL laboratory audit form, which is a favourable high score.

ASL reviewed the mine laboratory again in December 2006. Accuracy, precision, and other minor problems with the mine laboratory were recognized by Barrick personnel in 2006 and confirmed by Harwardt (2006) and ASL (2006). Barrick implemented a number of procedural changes in 2006 and the mine laboratory assays generally improved in 2007.
The QA/QC protocols and results were also reviewed by Scott Wilson RPA in 2007 (Scott Wilson RPA, 2008). The mine laboratory internal reference standard results provided to Scott Wilson RPA for 2007 indicated that the mine laboratory gold assays were accurate and generally unbiased. The acQuire database manager produces monthly and quarterly QA/QC reports. A quick visual review of the mine laboratory control charts in 2011 and 2014 by RPA revealed no significant problems.
RPA is of the opinion that the QA/QC practices at Veladero for exploration and production samples are acceptable and exceed industry standards.

12 DATA VERIFICATION
The Veladero resource database is regularly validated by MAGSA staff using data validation modules of Vulcan and Gemcom software programs to identify any inconsistencies or logical errors in the data. Mine staff also visually check the drill hole data on-screen on a regular basis. Outside auditors perform spot checks on the electronic database, sample submittal documents, QA/QC records, signed analytical certificates, drill logs, and other geologic records to identify errors, inconsistencies, or statistical anomalies.
As part of his annual audits of the Veladero sampling and QA/QC program, Dr. Barry Smee performed a spot check of data in the electronic database and the signed analytical certificates, and failed to find any discrepancies. He also checked sample tag numbers in the original sample books and found good correlation with sample numbers listed in the electronic database.
Smee (2001) states that a random selection of 18 Bondar Clegg assay certificates representing approximately 1,000 samples, or 1.5%, of the total 2000 and 2001 samples were compared to the master database values. No differences or errors were noticed between the two data sets.
During the 2003 resource audit, Resource Evaluation Inc. (REI) checked 5% of the Veladero assay intervals, comparing assay certificates with the electronic database, and found an error incidence of less than 0.5%, which is acceptable. REI did find an overall truncation of the third decimal place reported on some gold assays in the electronic database; this introduced a very slight degree of conservatism, less than one percent, into the raw assay data. This problem was related to incorrect export-import settings and not the master database. This problem was corrected and the entire database was re-checked according to Barrick (2005), specifically seeking any other errors in data formatting. No additional problems were found.
In 2007, RPA checked the electronic copies of the drill logs, assay certificates, and downhole survey data for holes DDH073 and RC628 drilled in 2005, RC660 drilled in 2006, and RC738 drilled in 2007 with the master database, and found essentially no errors. Only one minor data entry number reversal, related to the second and third decimals of the northing

	  	www.rpacan.com	

coordinate for hole DDH073, was found. RPA also used a number of Access queries, the Gemcom database validation routine, and visual checks and found essentially no database validation problems, which is remarkable considering the database size.
The blast holes have been in AcQuire since 2004. In July 2011, the exploration data was migrated to AcQuire. An electronic comparison confirmed no differences with the previous master database in MS Access. In addition, all of the collar coordinates for holes drilled since 2005 were verified by the mine surveyor (Vildozo, 2011) and the assays in 32 drill holes drilled from 1995 to 2004 were checked against the assay certificates and no errors were found (Berbe, 2011).
RPA is of the opinion that the drill hole database is acceptable to support resource and reserve estimation work.

13 MINERAL PROCESSING AND METALLURGICAL TESTING
METALLURGICAL TESTWORK
The original metallurgical testing to support the feasibility study was completed by McClelland Labs Inc. (MLI) in Reno, Nevada USA. Bottle roll tests, column leach tests, and agitated leach tests were performed in order to select the process to be used at Veladero and estimate operating costs and metal recovery.
During operation of the Veladero mine, frequent samples have been taken of ore being placed on the leach pad and tested to confirm that the recovery has not changed over time. Bottle roll tests are conducted for 96 hours and column tests run for 30 days. Over time, the tests have been shown to show excellent correlations with the recovery curves from the 90 day leach cycle on the heap leach pad. Metallurgical characteristics vary with gold grade, ore type, and whether the ore is crushed or run-of-mine (ROM). The Type 2 ore is associated with argentojarosite, which basically encapsulates free gold. Consequently, recovery is lower for Type 2 ore. The recovery equations used at Veladero are summarized in Table 13-1. The only change that has been made over the nine years the mine has been operating is to the Type 1 ore from both Filo Federico and Amable in the gold grade range from 0.5 g/t to 1.0 g/t.
The metallurgical domains are shown in Section 14, Figure 14-5.

14 MINERAL RESOURCE ESTIMATE
SUMMARY
Table 14-1 summarizes open pit Mineral Resources exclusive of Mineral Reserves as of December 31, 2013, based on a US$1,500/oz gold price. The EOY2013 Measured and Indicated Mineral Resources total 164.4 million tonnes averaging 0.68 g/t Au and 12.8 g/t Ag and contain 3.6 million ounces of gold and 67.9 million ounces of silver. In addition, the EOY2013 Inferred Mineral Resources total 27.9 million tonnes averaging 0.30 g/t Au and 12.9 g/t Ag and contain 269,000 ounces of gold and 11.6 million ounces of silver.

Notes:
 
 	1.	CIM definitions were followed for Mineral Resources.	
 
 	2.	Mineral Resources are estimated using an average gold price of US$1,500 per ounce.	
 
 	3.	Mineral Resources are estimated at gold cut-off grades that vary by material type from approximately 0.20 g/t Au to 0.48 g/t Au.	
 
 	4.	Mineral Resources are exclusive of Mineral Reserves.	
 
 	5.	Numbers may not add due to rounding.	
Silver recoveries are very low at Veladero, so silver is not considered for the resource and reserve cut-off grades. The cut-off grade estimates vary by material type and pit. There are essentially no reserves and resources remaining at Amable and Argenta. Most of the remaining resources are from Filo Federico Type 1 material. The ROM material is blasted material that is trucked directly to the valley-fill heap leach pad (VLF) and the Crush material passes through the two stage crushing circuit first.
The resource estimate gold cut-off grades are 0.200 g/t for Type 1 ROM material from Filo Federico, 0.328 g/t for Type 1 Crush material from Amable, 0.480 g/t for Type 2 Crush material from Filo Federico and Amable.

The resource model was prepared in March and April 2013, using all of the drill holes available up to February 2013, by Barrick Resource Geologist Lucas Berbé under the supervision of Barrick Technical Services Manager, Reserves and Resources Cristian Monroy. Barrick Technical Services Senior Resource Geologist Cristobal Valenzuela used Leapfrog to update the lithology and alteration wireframes. The resource estimation work is well documented in Monroy and Berbé (2013).
RPA’s review of the resource model applies not just to the Mineral Resources listed in Table 14-1, but also to the Mineral Resources that were converted to Mineral Reserves.
RPA reviewed the resource assumptions, input parameters, geological interpretation, and block modelling procedures and is of the opinion that the Mineral Resource estimate is appropriate for the style of mineralization and that the resource model is reasonable and acceptable to support the EOY2013 Mineral Resource and Mineral Reserve estimates.
RPA is not aware of any environmental, permitting, legal, title, taxation, socio-economic, marketing, political, or other modifying factors that could materially affect the Mineral Resource and Mineral Reserve estimates.
GEOLOGICAL MODELS
The Veladero geology department has developed a very good understanding of the Veladero geology. Geological models were constructed to provide geologic control for grade estimation and to provide parameters for mine planning. Geology models for lithology, alteration and structural sub-zones were built using Leapfrog software. The main faults have also been modelled for the current resource and a detailed 3D structural model has recently been completed and will be incorporated into the 2014 resource model. Interpretations were made by mine geology personnel on 50 m cross sections looking east-west for the lithology model and on 25 m cross sections looking east-west for the alteration model. Lines and control points based on the exploration drill holes, blast holes, and pit mapping were used in Leapfrog to create 3D geological wireframes.
The wireframes built for the main lithological, alteration and sub-zones are listed in Tables 14-2, 14-3, and 14-4, respectively. These wireframes were used to assign codes to the block model.

GEOLOGICAL DOMAINS
The main mineralization controls are the alteration and sub-zone domains. The mineralization typically cross-cuts the interpreted lithological boundaries, except for colluvium and steam heat. The steam heat lithology is mostly a barren post-mineralization alteration overprint. The base of the colluvium is mostly barren, however, it can host some mineralized fragments that are of economic interest locally.
The alteration codes are grouped into four simplified alteration domains which are listed below:
 
 	1.	Silicification-Advanced Argillic Domain (Alteration codes 1 to 3, and 9)	
 
 	2.	Argillic Propylitic Domain (Alteration codes 4 to 6)	
 
 	3.	Steam Heat (Alteration code 7)	
 
 	4.	Colluvium (Lithology code 8)	
The distinction between silica-alunite and alunite-silica alteration has no impact on grade interpolation, but has a significant impact on pit slope angles.
In order of decreasing importance, silicification, quartz-alunite, and alunite-quartz are the key alteration types associated with the mineralization. Based on the drill hole database alteration codes, approximately 75% of the total metres drilled are situated in the Silicification-Advanced Argillic Domain, approximately 4% are situated in the Argillic Propylitic Domain, approximately 1% are located in the Steam Heat Domain, 7% are in colluvium and approximately 14% have no alteration codes available.
GRADE DOMAINS
The drill hole and blast hole data are used to build 3D envelopes at 0.2 g/t Au and 25 g/t Ag from five metre bench contours. A separate lower grade indicator envelope was created based on blocks with a greater than 50% probability of grading over 0.1 g/t Au because the lowest cut-off grade in the past was lower than the 0.2 g/t Au envelope. The indicator was used to expand the 0.2 g/t Au envelope along strike and down dip. This results in three grade domains (Figure 14-4) and they were used to assign codes to the block model (Table 14-5).

TABLE 14-5 GRADE DOMAIN CODES
Barrick Gold Corporation – Veladero Mine

Code	  	Description	
0	  	Low (<0.1 g/t Au)	
1	  	Medium (0.1 to 0.2 g/t Au)	
2	  	High (>0.2 g/t Au)	
The High Grade Domain is treated as a hard boundary whereby only composites located in it are used to interpolate blocks situated in it. The Medium Grade Domain and Low Grade Domain are soft boundaries so composites from all three grade domains can target blocks in these domains, however, all composites are capped to 0.3 g/t Au before interpolating blocks in these domains.
Although this will not have a significant effect on the resource model, RPA concurs with Barrick’s plans to replace the 0.1 g/t indicator shell with one built using Leapfrog in the future.

METALLURGICAL DOMAINS
The metallurgical recoveries model was updated in November 2008. It is based on bottle roll tests realized by LMI laboratory and internal tests at Veladero for Filo Federico Type 1 material. All other metallurgical types maintain the 2002 metallurgical recovery model. Metallurgical recoveries vary with gold grade and metallurgical type (Section 13, Table 13-1). Silver recovery is very low and estimated to be 6.5% for Filo Federico Type 1 and Type 2 mineralization and 9.0% for Amable Type 1 and Type 2 mineralization. Metallurgical characteristics depend on mineralogy. In particularly, Type 2 is associated with argentojarosite, which basically encapsulates free gold. Consequently, recovery is lower for Type 2 mineralization. Figure 14-5 shows the spatial distribution for Types 1 and 2 at Amable and Filo Federico.
FIGURE 14-5 METALLURGICAL DOMAINS

DENSITY DATA
Tonnage factors are assigned based on the main alteration units (Table 14-6). All blocks in the silicified alteration domain are assigned a tonnage factor of 2.47 t/m³. All blocks in the silica-alunite and alunite-silica domains are assigned a tonnage factor of 2.36 t/m³. The tonnage factor for these alteration domains is lower because of the higher clay and vuggy silica content. All of the blocks related to the weaker alteration domains are assigned 2.45 t/m³. The steam-heated alteration blocks are assigned 2.10 t/m³ and the colluvium blocks are assigned 2.00 t/m³.

The tonnage factors are based on over one thousand density tests available up to the end of 2009 and there are no significant differences between these data and the density data available up to the end of 2011. RPA is of the opinion that the current tonnage factors are reasonable.
CUT-OFF GRADES
The resource cut-off grades (COG) are based on a US$1,500/oz gold price and the cost, recovery, and other parameters discussed in Section 15 Mineral Reserves. The cut-off grade estimates vary by material type and pit. Most of the resources are from Filo Federico Type 1 material. The ROM material is blasted material that is trucked directly to VLF and the CRUSH material passes through the two stage crushing circuit first. The resource and reserve cut-off grade estimate details for Filo Federico and Amable are very well documented in Chuquimango (2013).
The recoveries for the Type 2 material are too low to send directly as ROM and the Amable Type 1 COG is lower for CRUSH than ROM because the improved recovery more than offsets the crushing cost. The resource estimate gold COGs are 0.200 g/t for Type 1 ROM material from Filo Federico, 0.328 g/t for Type 1 CRUSH material from Amable, and 0.480 g/t for Type 2 CRUSH material from Filo Federico and Amable.

ASSAY STATISTICS
The assay statistics for gold are summarized in Table 14-7 and shown as boxplots in Figure 14-6. The statistics for Filo Federico (Norte) and Amable (Sur) are grouped by alteration types. The assays for 309,806 m of drilling average 0.43 g/t Au and have a very high coefficient of variation (CV) equal to 6.41.

FIGURE 14-6 ASSAY STATISTICS BOX PLOT

CAPPING OF HIGH GRADE VALUES
High assays are capped prior to compositing. The main capping levels are 40 g/t Au and 200 g/t Ag at Filo Federico. High assays in the quartz-alunite and alunite-quartz alteration at Filo Federico are capped to 3.0 g/t Au and 2.0 g/t Au, respectively. Lower capping levels, in the 0.1 g/t Au to 2.0 g/t Au range, are applied to a very small proportion of the assays located in the weaker intensity alteration domains (Table 14-8).

From Monroy and Berbé (2013)
The capping levels are primarily based on examining statistics, histograms, and log probability plots of the assays for each alteration domain at the Filo Federico and Amable zones. The grade times thickness products (GT) are used to estimate the approximate metal loss for each capping level. Some of the GT values are very high but they are mostly related to barren, low grade, and small alteration domains. Overall, the current gold capping levels reduce the contained gold at Filo Federico by approximately three to four percent.
Barrick also applied a second capping level directly to composites for some of the interpolation passes to further reduce the gold grade in some blocks with values deemed to be too high. The composites were capped to 15 g/t Au in the Amable sub-zone and to 10 g/t Au in the Filo Federico zone high grade domain.
Also, all composites are capped to 0.3 g/t Au before interpolating the Medium Grade Domain and Low Grade Domain blocks.

RPA concurs with the capping levels selected by Barrick. The production reconciliation results from 2011 confirmed that the previous capping levels were reasonable and the new levels have been relaxed slightly but are essentially unchanged, confirming that the current capping levels are reasonable. RPA’s view is that the 2013 production reconciliation results are anomalous due to other causes and that the capping levels are acceptable. Consequently, RPA is of the opinion that 2013 production reconciliation results cannot be used to calibrate the capping levels.
COMPOSITES
Drill hole sample data were composited into five metre lengths starting at the drill hole collars and resetting at the base of the colluvium.
The composite file has an additional length field to track the actual length of each composite that is supported by sample data. The grade interpolation used length weighted composites to help reduce the influence of shorter composites.

CONTACT PLOT ANALYSIS
Contact plots were generated for gold values to explore the relationship between the grade variable when moving from one geological domain to another.
The contact plots are constructed with Vulcan software. Vulcan searches for data with a given alteration code and then for data with another specified alteration code and groups the grades according to the distance between the two points. This allows for a graphical representation of the grade trends away from a “contact.” If average grades are reasonably similar near a boundary and then diverge as distance from the contact increases, then the particular boundary should probably not be used as a grade constraint and is referred to as a “soft” boundary. If the averages are distinctly different across a boundary, then the boundary may be important in constraining the grade estimation and the boundary is referred to as “hard”. Examples of contact plots for soft and hard boundaries are shown in Figures 14-8 and 14-9, respectively.
Domains with hard boundaries were used separately and soft boundaries were combined in the multi pass to interpolate grades.

VARIOGRAPHY
Barrick built omni-directional correlograms for Filo Federico, Amable, and the entire Veladero deposit using 15 m length composites greater than 0.1 g/t Au (Figure 14-10). The correlograms are smooth, clearly defined, and well-supported by thousands of composite pairs. The range is approximately 200 m and the relative nugget effect at approximately 10% is very low for a gold deposit. The ranges at 90% and 80% of the sill are approximately 110 m and 70 m, respectively.

RESOURCE ESTIMATION METHODOLOGY
The step by step resource estimation methodology is well described by Monroy and Berbé (2013). The Vulcan C shell file (estima_au13.csh) provides an excellent record of all the steps done in Vulcan to build the resource block model.
The Veladero Mineral Resource model extends from 2,405,900 m to 2,408,800 m east, 6,749,496 m to 6,753,396 m north, and 3,702.5 m to 4,852.5 m in elevation. The 5 m high by 5 m by 5 m block model is populated directly from the lithology, alteration, sub-zone, and grade envelope triangulations and a separate script is run to incorporate the grade domain codes related to the indicator grade domains.
The assays were composited into five metre lengths after capping raw assays. Composites for gold and silver were created. The composite lithology, alteration, sub-zone, and grade domain codes are back-flagged from the block model.
Veladero used multiple pass inverse distance square (ID²) to interpolate Au and Ag grades for all domains. Length-weighted composites are used.
The search ellipsoids for Au are generally horizontal pancakes for the lithological domains 7, 8 and for all the Amable Zone, and horizontal to sub-horizontal pancakes oriented at 0° to 330° with a range of dips (0° to -10°) for the Filo Federico zone. The search orientations vary for each zone. The longest search ellipsoid radii are 110 m by 110 m by 50 m for the final pass and the shortest search distances are 2.5 m by 2.5 m by 2.5 m for the first pass box search.
There are seven ID² passes used for the interpolation of grades. The pass numbers are included in Table 14-10. The first one is the general box pass, which is always run first and is based on a minimum of one composite. The second pass is used for the colluvium domain, which is based on 30 m by 30 m by 30 m radii and a minimum of one composite and a maximum of three composites per hole. The third and the fourth passes are used for the steam heat domain, inside the Medium Grade Domain and inside all grade domains respectively, which are based on 80 m by 80 m by 45 m radii and a minimum of one composite and a maximum of three composite, with a maximum of one composite per hole.

There are three more ID² passes used for each of the grade domains within each sub-zone domain and within each alteration domain and within the remaining lithological domains. Each of these passes actually comprises a number of actual interpolation runs.
Interpolation parameters for the fifth pass use a minimum of two composites and a maximum of three composites, with a maximum of one composite per hole. The fifth pass radii are the distances defined by 80% of the omni-directional sill. The sixth pass radii are shorter than the fifth pass radii. The sixth pass, however, uses a minimum of one composite and a maximum of three composites, with a maximum of one composite per hole. The seventh pass radii are the distances defined by 90% of the omni-directional sill. The seventh passes use a minimum of two composites and a maximum of three composites with a maximum of one composite per hole.

RE-BLOCKING TO FINAL RESOURCE MODEL
The five metre by five metre by five metre blocks are re-blocked into the final resource model, which has fifteen metre high by ten metre by ten metre blocks. The re-blocked grades are assigned based on tonnage weighting the original block grades and the geology and other codes are assigned based on majority rules.
Over time, Veladero has developed a sophisticated multi-pass interpolation process that works well. RPA is of the opinion that the Veladero resource estimation methodology is reasonable and acceptable.
RESOURCE ESTIMATE VALIDATION
MAGSA has validated the resource block model using five separate validation procedures. The results are provided in Monroy and Berbé (2013) and the reconciliation results are included below.
 
 	1.	Visual inspection of block and composite values on sections and plans	
 
 	2.	Reconciliation with the ore control model	
 
 	3.	Comparisons of block versus composite grade statistics, histograms, and cumulative frequency curves	
 
 	4.	ID² versus Nearest Neighbour (NN) swath plots	
 
 	5.	Tonnage-grade curve comparisons between the 2012 and 2013 models	
MAGSA and RPA visually compared the composite and block grades on plans and sections and found that they correlate very well spatially (Figures 14-11 and 14-12).

The official reconciliation data for the twelve months of 2013 indicate that the resource model underestimates the grade control tonnage by approximately 8%, underestimates the gold grade by approximately 23%, and underestimates the contained gold and silver by approximately 32% and 8%, respectively (Table 14-11).

RPA notes that a resource model that demonstrates this large of a positive bias when reconciled with the grade control data, would normally be rejected and redone, however, the differences have been attributed mostly to new high grade mineralized structures defined by the blast holes that were generally not intersected in the exploration drill holes. Although finding unexpected high grade mineralization in the pit is certainly a very positive outcome for Veladero, it may be difficult to make significant adjustments to the resource model without new drilling data, in RPA’s opinion. It is unknown for how long this positive reconciliation will continue. RPA concurs with Barrick’s plan to use the recently completed structural interpretation along with new geostatistical and other strategies to improve the resource model in the areas where higher than expected grades were encountered.
A longitudinal section showing the Veladero and Amable gold mineralization that is mostly situated between 4,000 MASL and 4,400 MASL is provided in Figure 14-13.

The NN and ID² swath plots are shown by elevation in Figure 14-14. It is clear on the swath plot that most of the resource is situated between approximately the 4,000 MASL and 4,400 MASL elevations. The NN (cyan) and ID² (red) average block grades are similar and the ID² grades are slightly lower than the NN grades as would be expected. The green line represents the NN interpolation constrained by the estimation domains and follows the ID² block grades very closely. There is very little difference between the ID² block grades based on cut and uncut composites.

RESOURCE CLASSIFICATION
The classification criteria are based on distances from 15 m composites to the 15 m by 10 m by 10 m block centroids and the number of holes as follows:
Measured Mineral Resources:
 
 	•	 	One composite within 10 m of a block.	
Indicated Mineral Resources:
 
 	•	 	Blocks Inside 0.2 g/t Au Envelope : At least two composites from two drill holes that are situated 10 m to 70 m from a block or one composite from one drill hole that is located 10 m to 35 m from a block.	
 
 	•	 	Blocks Outside 0.2 g/t Au Envelope : One composite from one drill hole that is located 10 m to 35 m from a block.	
Inferred Mineral Resources:
 
 	•	 	Blocks Inside 0.2 g/t Au Envelope : At least two composites from two drill holes that are situated 70 m to110 m from a block.	
 
 	•	 	Blocks Outside 0.2 g/t Au Envelope : One composite from one drill hole that is located 35 m to 70 m from a block.	
 
 	•	 	All Colluvium and Steam Heat Blocks: At least two composites from two drill holes that are situated 35 m to 110 m from a block or one composite from one drill hole that is located 0 m to 35 m from a block.	
The 70 m and 110 m distances correspond to the omni-directional correlogram ranges at 80% and 90% of the sill. Figure 14-10 shows the omni-directional correlograms using all of the 15 m gold composites greater than 0.1 g/t at Filo Federico, Amable, and the two areas combined.
RPA recommends that MAGSA consider two minor modifications to the resource classification criteria in the future. Firstly, Inferred classification should be automatically assigned to all blocks located outside the 0.10 g/t Au indicator envelope. Secondly, Inferred classification should be assigned to blocks centered on isolated drill holes. Neither of these changes would have a significant impact on the current resource classification.

Technical Report NI 43-101 – March 27, 2014	  	Page 14-29

Resource categories assigned to each block were post-processed to reduce isolated blocks enveloped within blocks of a different category and to produce more continuous areas with the same classification categories. It is RPA’s opinion that the application of a classification category clean-up script is best practice.
RPA’s view is that the Inferred classification criteria are conservative, and that overall, the classification criteria are slightly conservative. RPA is of the opinion that the classification criteria are reasonable and acceptable and comply with the CIM (2010) definitions. The resource classification model at the 4,150 m elevation is shown in Figure 14-15.

15 MINERAL RESERVE ESTIMATE
The resource estimates discussed in Section 14 were prepared using industry standard methods and appear to provide an acceptable representation of the deposit. RPA reviewed the reported resources, production schedules, and cash flow analysis to determine if the resources meet the CIM Definition Standards for Mineral Resources and Mineral Reserves, to be classified as reserves. Based on this review, it is RPA’s assessment that the Measured and Indicated Mineral Resource within the final pit design at Veladero can be classified as Proven and Probable Mineral Reserves.
The open pit Mineral Reserves are estimated to be 172 million tonnes at 0.87 g/t Au and 15.9 g/t Ag, containing 4.8 million ounces of gold and 88 million ounces of silver and are classified as Proven and Probable Reserves as presented in Table 15-1. Stockpile and leach inventory reserves are reported in the table as well. Over 99% of the open pit reserves are located within the Filo Federico pit of Veladero, with the remainder coming from the Argenta pit, which is scheduled for depletion in 2014.

Notes:
 
 	1.	CIM definitions were followed for Mineral Reserves.	
 
 	2.	Mineral Reserves are estimated at a variable cut-off grade based on process cost, recovery and profit. The cut-off grades vary from approximately 0.27 g/t Au to 0.64 g/t Au.	
 
 	3.	Mineral Reserves are estimated using an average gold price of US$1,100 per ounce and an US$/ARG exchange rate of 7.8.	
 
 	4.	Numbers may not add due to rounding.	
Mineral Reserves for EOY2013 have decreased significantly since EOY2011 after consideration for mining depletion. The main reasons for the decrease is the reduction in gold price for reserve reporting from US$1,200/oz to the current US$1,100/oz and an increase in operating costs.

99% of in-situ Mineral Reserves are located within the Filo Federico pit, with open pit mining operations scheduled to be complete in 2019. Remaining in-situ Mineral Reserves are from the Argenta pit, where production is scheduled to be complete in 2014. Prior to 2014, open pit mining also took place in the Amable pit within the Veladero area. Mineral Reserves at Amable were exhausted in 2013, with no future plans to recommence mining operations in this pit. Figure 16-1 presents a general site layout diagram of Veladero. Figure 16-2 presents a close-up of the Veladero area operations and heap leach facilities.
The Filo Federico ultimate pit will measure approximately 2.0 km along strike, typically 1.0 km across, and have a maximum depth of approximately 650 m. The Amable ultimate pit measures approximately 1.0 km in diameter with a maximum depth of approximately 530 m. The Argenta ultimate pit will measure approximately 1.0 km along strike, typically 0.5 km across, and have a maximum depth of approximately 300 m.
Final arrangement of the Veladero waste rock facilities is for the continued development of surface dumps along contour to either side of the Filo Federico ultimate pit. This results in the backfilling of the Amable pit to the south, and the expansion of surface dumps on the mountain side slope to the west of Filo Federico. In addition, there are surface dumps to the southwest of the Amable pit that have been developed from Amable pit operations; this area directly overlooks the heap leach facility to the south. At Argenta, waste rock is surface dumped to the southeast adjacent to the ultimate pit.
Processing is based on a single VLF pad that receives crushed and ROM ore with final delivery to the pad by mine haul truck. The VLF is located less than 1.0 km to the south of the Amable ultimate pit, and it is almost 4.0 km south of the Filo Federico ultimate pit haul ramp exit where the majority of the remaining reserves are located.

The majority of remaining reserves are scheduled for crushing prior to placement on the VLF as this typically offers a higher profit margin than ROM placement. The crushing facilities are located approximately 1.5 km east of the Filo Federico ultimate pit haul ramp exit. After crushing, the ore is conveyed by overland conveyor approximately 3.7 km south towards the VLF where it is either directly loaded to a haul truck or stockpiled. Haulage distances from the conveyor to the VLF currently start at 0.5 km and go up to approximately 2.0 km. During the final VLF phase, haulage distances will be up to 5.0 km one way.
Mining an average of approximately 30 Mtpa of Mineral Reserves is scheduled for Veladero over the next six years. Waste rock mining varies by year from a high of 63 Mt in 2017 to a low of five million tonnes in the final year of operations, averaging 45 Mtpa during full production years.
MINE DESIGN
Mine operations are exclusively by open pit method, with a fleet of 218 tonne rigid frame haul trucks combined with a variety of diesel powered hydraulic shovels and front end loaders as the primary loading equipment. Haul trucks are also utilized to transport ROM ore directly to the VLF, along with crushed ore to the VLF for placement. A fleet of large diesel powered blast hole rigs are employed for production drilling, and blasting is required other than for the occasional unconsolidated material at surface when starting a new pushback.
The Mineral Resource model, described in Section 14, is exported from Vulcan software and imported into Q’Pit Inc.’s Q’Pit software (Q’Pit). The mine model is prepared in Q’Pit, applying metallurgical recoveries based on material types, calculating potential block revenue, and defining slope sectors based on alteration type. The mine model is exported from Q’Pit and imported into Gemcom’s Whittle 4.X software (Whittle) for open pit optimization using the Lerchs-Grossmann algorithm. Pit shells generated by Whittle are imported into Q’Pit for mine design, Life of Mine (LOM) production scheduling, and Mineral Reserve reporting.

Table 16-2 presents the parameters used for developing the mine model and running the open pit optimizations in Whittle. The gold and silver recovery algorithms presented are for Type 1 ore in the Filo Federico pit only. As noted previously, over 99% of remaining reserves are located in the Filo Federico pit. In addition, over 95% of ore in Filo Federico pit is Type 1 ore.

The Whittle optimizations are run at a base case gold price of US$1,100/oz; a range of gold prices are reviewed to test sensitivity to pit limits at lower and higher gold prices. The cash optimum pit at US$1,100/oz gold is selected for use in the ultimate pit design as it maximizes reportable ounces and it is very similar to the best net present value pit.
Mining cost is an average of all tonnes moved based on a detailed LOM operating cost estimate and includes mine sustaining costs. Incremental haulage costs are also applied dependent on pit location and processing path. No mining recovery or mining dilution is assumed in the Whittle optimization as this is factored into the resource model by a combination of block size selection (10 m by 10 m by 15 m vertical), good continuity of the ore zones laterally and vertically, and a gradational halo of marginal mineralization surrounding the above cut-off grade mineralization. Mining factor assumptions are verified through good historic reconciliation performance of the resource model to the ore control model and dispatch reporting.
Two material ore types for processing are identified: Type 1 and Type 2. Each ore type can be processed as ROM without crushing or with crushing (Crush). Gold and silver recoveries are applied to individual blocks based on block properties. Revenues for ROM and Crush process paths are calculated and the method with the highest profit margin is typically selected unless there is available crusher capacity. If available capacity exists in the crusher, ore is preferentially passed through the crushing system if still profitable to take advantage of increased leach kinetics and higher recoveries.
Heap leach expansion costs are applied to both ROM and Crush ores, whereas all general and administrative costs are applied to Crush tonnage only as crushing is scheduled at a fixed annual capacity whereas ROM is variable on an annual basis.

The crushing rate is the design capacity for both crushers at the permanent crushing station located directly east of the Filo Federico pit. The average LOM gold recovery of 76.6% is for all stated Mineral Reserves.
Cut-off grades for reporting Mineral Reserves are calculated utilizing the following formula:
COG = RAu * SPAu / 31.1035 * (1-ET) – (Cp + Hle + IMc + Cga + Ccp) – ((RAu * SPAu) / 31.1035 * RT)

Where, COG	  	=	 	internal (breakeven in-pit) gold equivalent cut-off grade	
			
  Cp	  	=	 	processing cost	
			
  Hle	  	=	 	heap leach expansion cost	
			
  IMc	  	=	 	incremental and sustaining mining cost	
			
  Cga	  	=	 	general and administrative cost	
			
  Ccp	  	=	 	closure plan cost	
			
  RAu	  	=	 	gold metal grade recovered	
			
  SPAu	  	=	 	gold metal selling price after per ounce costs, fees, and payables	
			
  TR	  	=	 	metal TC/RC and transport cost	
			
  ET	  	=	 	export tax	
			
  RT	  	=	 	royalties tax, Province and IPEEM	
Silver is also considered for in the mine planning, however, it is not considered significant due to low process recoveries and it doesn’t have a significant impact on the final pit limits.
Table 16-3 details internal cut-off grades for Filo Federico by material type and process method. The resource and reserve cut-off grade estimate details are well documented in Chuquimango (2013).

The Crush profit cut-off grades reported in Table 16-3 are the grades at which leaching with crushing is both profitable and more profitable than leaching as ROM. For all Type 2 ore the Crush profit cut-off grades are lower than the ROM cut-off grades thus all these ores should be crushed as this is the most profitable processing method. In the case of Filo Federico Type 1 ore, the reported Crush profit cut-off is higher than the ROM cut-off.
In addition to the mine reserve cut-off grades used for production scheduling, a floating cut-off grade is employed in daily operations, which is updated as required to reflect the current gold price market. Mineralized material that falls between the mine reserve cut-off grade and floating cut-off grade is dispatched to a long term stockpile within the waste rock facilities (WRF) footprints for possible processing at the end of regular mining operations depending on market conditions at that time. This material is not reported as reserves.
Ultimate pit design is based on the optimum cash pit shell from Whittle at US$1,100/oz gold. Additional pit shells are used as guides to design pit phases leading up to the ultimate pit, in order to maximize project net present value while maintaining a practical mine sequence and production schedule. Pit designs, long term production scheduling, and reserve reporting are completed in Q’Pit. Pit mid bench lines are digitized in Q’Pit, honouring the Whittle pit shell outline and all pit wall slope constraints, and include haulage ramps. Due to the open pit location on mountain side slopes, the majority of haulage ramps are developed external to the pits using ROM waste rock for fill material.
In RPA’s opinion the ultimate pit design honours the Whittle optimum pit shell, other than in a few minor areas where access ramps are required or to allow future access if additional pit phases are added. For the most part, pushback distances of over 100 m exist in the pit phase design, allowing sufficient room for large scale operations.

Short range mine planning and detailed pit design are completed in Minesight software where the ore control model resides. Detailed mine design parameters are presented in Table 16-4. Pit wall slopes vary based on geologic domain (effectively follows the alteration model), as per recommendations provided by Golder Associates discussed later in this section.

The 32 m haul road width includes a single shoulder berm and water collection ditch.
RPA has reviewed the pit designs and is of the opinion that these follow good engineering practice. All phases are designed with sufficient room to allow for operations, and roads and ramps have been delineated. Preparation of sufficient production benches in the Filo Federico pit phase development will be key to achieving production targets.
GROUND CONDITIONS / SLOPE STABILITY
The geotechnical analysis to develop slope design parameters for Veladero was completed by Golder Associates (Golder). Golder has evaluated the pit slope design for the ultimate pit and provided updates using new geologic, geotechnical, and structural information presented from recent mining in the various geologic domains. A current focus is in reviewing past results for the Filo Federico pit along with pre-splitting operations at the Amable pit in order to determine if it is possible to increase the inter-ramp angles for final pit wall development.
Table 16-5 summarizes the current slope design recommendations for Veladero listing the inter-ramp slope angle (IRA), bench face angle (BFA), and catch berm width (CBW). Defined slope sectors are based on the rock alteration type.
Figure 16-3 presents a plan view of the slope sectors for the Filo Federico pit along with the Amable pit where open pit operations were completed in 2013.

The final pit slope in Amable has wall heights up to 525 m; as part of the LOM plan the Amable pit is to be backfilled with waste material from Filo Federico pit. The final pit slope in Filo Federico will achieve wall heights up to 650 m. RPA is of the opinion that the work that has been completed by Golder is of an appropriate scope and the pit design is based on reasonable engineering analysis and assumptions.
A sophisticated system of automated and manual data collection equipment has been installed at Veladero for monitoring pit wall activity. In addition, a network of prisms, extensometers, piezometers, and other instruments, are installed and monitored for slope stability of pit walls, the VLF, and WRFs. Results are reviewed by Golder and form part of ongoing recommendations for design.

PRODUCTION SCHEDULE
Only Mineral Resources with classification of Measured or Indicated can be converted to Proven or Probable Mineral Reserves for production scheduling. A mine production schedule was developed from the mine design that targets the crushing capacity of 30 Mtpa (83,000 tpd) with up to an additional 10,000 tpd ROM production. Total capacity is based on moving up to 92 Mtpa (255,000 tpd) through 2017 with production decreasing thereafter and completion of mining in 2019. In RPA’s opinion, sufficient mine fleet capacity exists to meet these production targets in suitable operating conditions.
With the completion of Amable mining operations in 2013, and the scheduled completion of Argenta mining operations in 2014, all remaining scheduled production will come from the Filo Federico pit. This will result in an increase in mine traffic congestion along with an increased rate of pit phase bench advancement, which will impact productivities. RPA cautions that this will challenge the forecast production rates. RPA has reviewed unit cost sensitivity to production rates, and notes that within a reasonable range there is little change to the economic pit limits.
During regular mining operations and as part of the LOM plan, ore stockpiles are utilized.
WASTE ROCK
For the Veladero area, there are two main WRFs identified in the LOM plan, the North WRF (N-WRF) and the South WRF (S-WRF). The N-WRF is to the north and west of Filo Federico pit on a mountain side slope at elevations between 4,000 MASL and 4,700 MASL. The S-WRF is south and west of Filo Federico pit, immediately north of the east-west elongated VLF. The S-WRF includes backfilling of Amable pit, and is at elevations between 4,100 MASL to 4,600 MASL. The WRFs are designed as multiple lifts with pre-closure face heights less than 200 m from toe to crest, except for a single area in the N-WRF with a pre-closure face height of approximately 350 m. Figure 16-4 is an isometric view of the final WRF design for the Veladero area.
Segregated within the WRF is rock with low grade gold mineralization (between the mine reserve cut-off grade and the floating cut-off grade) which may be reclaimed and processed at the end of the production schedule if profitable market conditions exist.

			
Barrick Gold Corporation – Veladero Mine, Project #2254
Technical Report NI 43-101 – March 27, 2014	  	Page 16-13  	

			
	  	www.rpacan.com	

Combined remaining capacity of the N-WRF and S-WRF is over 400 million m 3 , while there is less than half this amount of waste material in the LOM production schedule.
In addition to the WRFs, there are numerous fill roads on the mountain side slope that provide access from the pits to the WRFs, process facilities, and other site infrastructure. There is no waste rock in the mine plan that requires special handling or containment during or post open pit operations.
Waste rock at Argenta is stored on surface immediately to the southeast of the pit. The WRF has been built up in 10 m to 15 m lifts at elevations between 4,100 MASL and 4,300 MASL.
Sufficient waste rock storage capacity exists within the WRFs to support the mine production schedule and Mineral Reserve statement. A comprehensive WRF geotechnical report was prepared by Golder in 2002.

VALLEY-LEACH FACILITY
A single VLF is located south of the Amable pit and S-WRF. The final proposed VLF design is approximately 5.0 km east to west by 1.0 km north to south, with a footprint of approximately 270 ha. Elevations range between 4,000 MASL and 4,300 MASL, with a maximum bench elevation of approximately 4,375 MASL. The maximum vertical height within the VLF is approximately 200 m, built-up in 30 m lift intervals. Additional approval is required to complete all VLF phases as proposed, discussed in detail in Section 20, however, the current permits allow for placement of 100% of the stated Mineral Reserves. The final layout of the VLF, as shown in Figure 16-5, is presently under review to optimize placement of the current Mineral Reserves.
Proven and Probable Reserves in the LOM production schedule, including stockpiles and excluding leach inventory, total approximately 178 million tonnes, significantly less than the proposed remaining VLF maximum design capacity of approximately 630 million tonnes.
A comprehensive VLF geotechnical report was prepared by Vector Argentina S.A. in 2007.

MINE EQUIPMENT
Veladero operations are typical truck/shovel open-pit operations, with all major production equipment equipped with GPS and dispatch systems. For production scheduling, equipment horsepower is de-rated for the operating elevations.
The current haul truck fleet consists of 41 Caterpillar 793 trucks rated for a 218-tonne payload, which is also the maximum fleet size for the production schedule. In addition, there are four Caterpillar 785 haul trucks rated for 140-tonne payload operating in Argenta pit. The truck fleet’s maximum annual hauling capacity is approximately 125 Mt, sufficient to meet peak material movement of 92 Mt in 2017.
Loading operations are conducted using a variety of diesel powered machines for production with the current fleet scheduled as follows:
 
 	•	 	Three Liebherr 996 face shovels with 36 m 3 buckets;	
 
 	•	 	Two Komatsu PC 5500 face shovels with 29 m 3 buckets; and	
 
 	•	 	Four Caterpillar 994 front end loaders with 19 m 3 buckets.	
The diesel powered production drill fleet currently consists of:
 
 	•	 	Four Drilltech D90Ks;	
 
 	•	 	Three Ingersol Rand DMM2s, and	
 
 	•	 	Two Atlas Copco PV271.	
All drills are equipped with a 260 mm drill bit. The Drilltech and Atlas Copco drills are capable of single pass drilling the 15 m bench height plus one metre of subdrill, while the Ingersol Rand drills require an additional drill rod to achieve the required depth. Total production drill capacity is approximately 90 Mtpa, just below peak material movement of 92 Mt in 2017. In addition, consideration is being made for an increase in wall control blasting at final walls of Filo Federico, which will further reduce total drill capacity. A plan is in place to increase drill capacity through new acquisitions in the current year.
For blasting, a combination of emulsion and ANFO are loaded into each hole. Typically, the bottom 25% to 35% of the column is loaded with emulsion, topped off with ANFO. The pit is

	  	www.rpacan.com	

typically dry (there are no pit dewatering wells in operation and limited surface water), thus the purpose of the emulsion is to increase blasting power. Powder factor targets for Filo Federico are 0.45 kg/t in ore and 0.3 kg/t to 0.35 kg/t in waste.
Mine mobile equipment production rates were reviewed with availability and utilization to see if mining production rates and costs are appropriate. RPA is of the opinion that the equipment productivities for the production fleet are reasonable. The current mine equipment fleet is listed in Table 16-6, along with major support equipment.

MANPOWER
Veladero operates on a 24-hour per day, 365 days per year schedule. For most operating positions, there are four work crews with two on site at any time working two 12-hour shifts per day, 14 days on followed by 14 days off.
Mining operating manpower is based on approximately four operators for each operating position. Mining manpower for operations, maintenance including process maintenance, and technical services in 2014 is budgeted for approximately 900 staff and employees. RPA considers the manpower estimates to be reasonable.
MINE INFRASTUCTURE
Veladero has all necessary infrastructure for a large open pit mine operation in a remote location at high altitude. Mining related infrastructure includes a truck shop, truck wash facility, warehouse, fuel storage and distribution facility, explosive’s storage and magazine sites, and electrical power distribution and substations to support construction projects and mine operations.

17 RECOVERY METHODS
Gold is recovered from ore at Veladero using ROM and crushed ore cyanide heap leaching, and a Merrill-Crowe zinc cementation gold recovery plant. The lower gold grade ore, i.e., above the cut-off grade for ROM ore and below the cut-off grade for crushed ore, is mined and trucked to the VLF and co-mingled with crushed ore (in the past, ROM ore was stacked in a separate area from crushed ore). Final delivery to the pad for ROM and crushed ore is by haul truck; trucks dump over the side of the pad and the ore is pushed using a track-mounted dozer.
CRUSHING PLANT
A simplified process flowsheet for the crushing circuit is provided in Figure 17-1.
Ore that has a gold grade above the cut-off grade for crushed ore is trucked from the mine or stockpiles and crushed in one of two two-stage crushing circuits to a nominal size of 80% passing (P 80 ) 42 mm. The crushing plant was expanded in 2009 to increase the capacity to approximately 85,000 tpd, i.e., 52,000 tpd through line one and 33,000 tpd through line two. Haul trucks dump directly into the primary 1,270 mm by 1,650 mm gyratory crushers. After crushing, the ore from line one is discharged into a surge pocket and transferred to a 2,000 t live capacity covered stockpile via an apron feeder and a belt conveyor. The primary crushed ore from line two is reclaimed from the surge pocket and placed on a belt conveyor. From the belt conveyor the ore can either go directly to a secondary crusher surge bin or be transferred to the covered stockpile.
The primary crushed ore is reclaimed from the stockpile and conveyed to a splitter chute to feed two scalping screens that operate in parallel in line one to remove the material that meets the required size criteria. The oversize from the screens discharges to two MP800 standard cone crushers. Line two is similar to line one except it has only one scalping screen and one secondary cone crusher. The secondary crushers operate in open circuit so the crushed ore and the undersize from the scalping screens are conveyed to a 3.7 km long overland conveyor belt for transport to a truck loadout bin that is located adjacent to the processing plant near the heap leach pad. Lime is added to the ore as it is transported on the overland conveyor belt.

VALLEY-LEACH FACILITY
The ore from the loadout bin is loaded into mine haul trucks for transport to the VLF where it is stacked in 15 m lifts. The drip emitters are buried approximately 10 cm to 15 cm to maximize distribution and minimize freezing and evaporation. The maximum height of the leach pad will be less than 200 m, with 150 m being typical. At present, the pad is approximately 80 m high.
An ongoing expansion of the leach pad to the east is continuing in phases. At the time of the visit, liner was being placed in Phase 5.
Approximately 250,000 m 3 of ore is actively under leach at any given time with dilute cyanide leach solution applied using drip emitters. The nominal capacity of the solution pumping system is 2,066 m 3 /h. Pregnant solution is collected by the dam, at the toe of the leach pad, and pumped to the Merrill Crowe recovery plant.
MERRILL CROWE PROCESS PLANT
The Merrill-Crowe plant flowsheet is shown in Figure 17-2.
The pregnant solution is clarified in pressure leaf filters and stored in a clarified solution tank. From the tank, solution is pumped to a vacuum de-aeration tower which removes the dissolved oxygen from the solution. Zinc dust is fed to the solution as it exits the de-aeration tower and the precious metals are removed from the solution as solid precipitate. Plate and frame filter presses are used to separate the precipitate from the solution. The solution is collected in a barren solution tank, cyanide, lime, and make-up water are added to the solution and it is re-circulated to the valley-leach facility for reuse.
The zinc precipitate is collected from the filter presses and processed in retorts designed to recover mercury vapors from the precipitate as it is heated under vacuum. By-product mercury is collected and stored on site for longer term stabilization, transfer, or sale.
The dried precipitate is mixed with flux and smelted in electric induction furnaces. Gold doré that is produced by the refining process is shipped off site for further refining to produce fine gold and silver.

COMMENTS
The crushing circuit and conveyor circuit had lower than expected availability due to equipment maintenance issues. Measures are being implemented to deal with these issues. The ore is quite abrasive, resulting in frequent liner changes, which reduces availability. In addition, the overland conveyor experienced greater than desired downtime, resulting in in mine trucks having to be diverted to transfer leach pad material from the crushing plant.
With the curtailment of mercury sales, long term storage will be required, and is being addressed. As well, studies to find acceptable methods of disposal are ongoing.
Senior supervision in the plant has been replaced in the last few months. It is anticipated that the new team will be effective in increasing operational availability.

18 PROJECT INFRASTRUCTURE
Veladero infrastructure and services have been designed to support an operation of over 85,000 tpd of ore to a VLF and a nominal 280,000 tpd of total material mined. Due to the remote location, the property is self-sufficient with regard to the infrastructure needed to support the operation.
ACCESS
The Veladero mine site is located approximately 280 km northwest of San Juan, the provincial capital of San Juan Province, Argentina, and also the closest major population and commercial centre. Access is via paved road heading north of San Juan for approximately 205 km to the main gate near Tudcum. From the main gate at elevation 1,930 MASL, it is approximately 155 km to the Veladero mine site along a well maintained all season gravel road passing over Conconta Pass at approximately 4,850 MASL. The total route distance is approximately 360 km one way, and takes approximately six hours for a light vehicle in typical driving conditions.
Road maintenance from the main gate to the mine site is performed by contractor.
Most consumables are transported along this route by truck. Alternative road access is available from the Chilean side, but is not used for regular transport of goods or people.
MINE SITE FACILITIES
The mine and VLF are located at the mine site at elevations between 3,800 MASL and 4,700 MASL. Also, located in the same vicinity are the crushing facilities and Merrill-Crowe recovery plant, on-site facilities (safety/security/first aid/emergency response building, assay laboratory, plant guard house, dining facilities, and offices); related mine services facilities (truckshop, truck wash facility, warehouse, fuel storage and distribution facilities, reagent storage and distribution facilities), and other facilities to support operations.

	  	www.rpacan.com	

ACCOMMODATIONS
Mine camp facilities are located approximately seven kilometres southeast and downslope of the Veladero open pit operations at approximately 3,850 MASL. Permanent accommodations are available for all Veladero employees and visitors (the “hotel”). Contractor accommodations are also provided near the Veladero accommodations. Site accommodations are sufficient for the Veladero workforce, contractors, and consultants, with approximately 3,000 beds in total.
WATER
Potable water is provided by two water wells. The water is treated using reverse osmosis. One system is located near the hotel and the other is located near the construction camp. Potable water is not available at the truck shop.
The water supply for industrial usage ( i.e., process and dust control) is secured from the Rio de las Taguas.
ELECTRICAL
Veladero is self-sufficient with regard to the supply of electrical energy. Energy is generated on site using a 2 MW wind turbine and diesel generators located throughout the property. The total electrical supply is 22 MW.
UTILITIES
The Veladero site has four aerobic sewage treatment plants and one prototype sewage treatment plant that utilizes worms instead of bacteria to break down the domestic waste. There are also sewage treatment plants located along the access road at Sepultura and Peñasquito.
DISPOSAL AND DRAINAGE
In addition to carefully monitored discharges from the sewage treatment plants, Veladero has an extensive disposal and recycling program. No waste disposal takes place on site. All

materials that are to be disposed of including domestic and industrial rubbish, used petroleum productions, and hazardous waste materials are delivered to a central area where they are managed by a contractor. The materials are sorted and appropriately packaged for shipment to San Juan where they are recycled or sent for disposal at an appropriate facility.
BUILDINGS AND FACILITIES
Veladero has buildings and facilities needed to support the operation including warehouse, truck shop, office buildings, etc.
COMMUNICATIONS
The mine site has a communication network of telephones and licensed UHF radio repeaters within the mining areas. Outside these areas, communication is generally by means of UHF CB radio or satellite phone only.

19 MARKET STUDIES AND CONTRACTS
MARKETS
Gold and silver are the principal commodities at Veladero and are freely traded, at prices that are widely known, so that prospects for sale of any production are virtually assured. Prices are usually quoted in US dollars per troy ounce.
Operations at Veladero are expected to produce an annual average of approximately 660,000 ounces gold and 950,000 ounces silver annualized over the remaining six year mine life. At the reserve metal prices, over 95% of Project revenue is derived from gold sales.
CONTRACTS
MAGSA has a contract for the purchase of gold and silver doré from Veladero with Barrick. Currently, there are no forward sales or hedging for gold. In the case of silver, a contract is in place whereby Silver Wheaton buys 100% of silver produced for US$13.69/oz for the first 8% of recovered silver ounces. This contract is estimated to expire when Barrick has satisfied its requirements of a completion guarantee on its Pascua-Lama project. All silver recovered above the first 8% is controlled by Barrick.

20 ENVIRONMENTAL STUDIES, PERMITTING, AND SOCIAL OR COMMUNITY IMPACT
ENVIRONMENTAL STUDIES
Environmental studies are on-going at Veladero. Of particular interest is that the population of guanaco is monitored closely and has had an over 500% increase since the beginning of the Project.
On September 30, 2010, the National Law on Minimum Requirements for the Protection of Glaciers was enacted in Argentina and came into force in early November 2010. The federal law bans new mining exploration and exploitation activities on glaciers and in the “peri-glacial” environment and subjects ongoing mining activities to an environmental audit. If such audit identifies significant impacts on glaciers and peri-glacial environment, the relevant authority is empowered to take action, which according to the legislation could include the suspension or relocation of the activity. In the case of the Veladero mine, the competent authority is the Province of San Juan. In late January 2013, the Province announced that it had completed the required environmental audit, which concluded that Veladero does not impact glaciers or peri-glaciers. The constitutionality of the federal glacier law is the subject of a challenge before the National Supreme Court of Argentina, which has not yet ruled on the issue.
PROJECT PERMITTING
The fourth update of the Environmental Impact Assessment for the Veladero Project was submitted to the Mining Authority of the San Juan Province on November 2011.
A large number of environmental permits are in place at Veladero to manage and monitor such things as:
 
 	•	 	Vehicles	
 
 	•	 	Vehicles in communities along the access route	
 
 	•	 	Vibration on highways	
 
 	•	 	Noise	
 
 	•	 	Fauna	
 
 	•	 	Flora	
 
 	•	 	Water

	  	www.rpacan.com	

 	•	 	Gasses emitted from the processing plant	
 
 	•	 	Generators	
 
 	•	 	Archeological sites	
 
 	•	 	Effluents from water treatment plants	
 
 	•	 	Surface and groundwater monitoring	
 
 	•	 	Weather stations	
In March 2013, an accumulation of solution within Veladero’s leach pad collection system was identified. Pumping rates were increased to reduce the accumulated solution, recirculating the same to the pad. The situation was reported to the appropriate local authority, which performed a site inspection and started an administrative investigation proceeding.
Veladero is implementing certain measures requested by the local authority following that site inspection. Production has been impacted by a build-up of ounces on the leach pad due to restrictions imposed by the authority that affect the amount of solution that can be applied to the pad.
Barrick is in discussions with regulatory authorities with respect to permit amendments to reflect the current circumstances and to allow operation of the leach pad in alignment with permit requirements.
The amendments were described in the addendum to the fourth EIS update submitted in November 2013 as well as in certain other environmental filings.
Barrick has received advanced authorization to implement certain of the permit amendments and expects to receive full authorization of the requested amendments pursuant to these discussions when the addendum to the fourth EIS update is approved. However, failure to obtain the permit amendments in a timely manner would have an increasing impact on 2014 production at Veladero. In RPA’s opinion, it is reasonable to assume that the current situation will be resolved in a timely manner, thus not impacting the current Mineral Resource and Mineral Reserve estimates.
Veladero have developed a participative monitoring program. In this program, water sampling is done by people from the local communities and the samples are submitted to laboratories of their choice. They also get the results from the laboratories. The transparency generates trust which has been very affective in providing Veladero with the social licence to operate the mine.

Technical Report NI 43-101 – March 27, 2014	  	Page 20-2  	

			
	  	www.rpacan.com	

Veladero has an Environmental Management Plan that is certified under the ISO 14001 standards. It is audited annually and it must be recertified every three years. Veladero was last re-certified in 2013.
It is also certified by the International Cyanide Management Code. There are annual re-certifications required, and Veladero was recertified in May 2013.
Reports of the monitoring results are submitted to the authorities every six months.
The authorities conduct site inspections at Veladero on a regular basis. Written reports of comments are distributed and Veladero responds to the comments, as required.
Currently, RPA believes that there are no environmental issues, which directly affect reserves or resources. The environmental requirements are managed by an on-site staff of professionals and technicians and the legal department in the San Juan office.
SOCIAL OR COMMUNITY REQUIREMENTS
Veladero is actively involved with communities in the San Juan province. Although the mine is in a remote location and direct involvement with people that are not employees of the mine is not common, programs such as the community water sampling has generated an atmosphere of trust that enhances the operation of Veladero.
MINE CLOSURE REQUIREMENTS
The closure plan is based on the LOM plan developed by MAGSA. The reclamation plan was developed to allow, when practical, closure and rehabilitation activities to be carried out simultaneously with mining activities. This rehabilitation in parallel will allow the performance of certain tasks during the operation of the mine, reducing closure costs and the schedule for completing the tasks at the end of the mine life, however, the most important closure activities will not begin until the mining operations have ended.

			
Barrick Gold Corporation – Veladero Mine, Project #2254
Technical Report NI 43-101 – March 27, 2014	  	Page 20-3  	

			
	  	www.rpacan.com	

Closure activities will be implemented to rehabilitate the land wherever possible, physically stabilizing the soil and re-grading the affected areas to obtain topography similar to that of the surrounding areas. These closure activities will also include the chemical stabilization of affected materials and the physical stabilization of the valley fill leach facility (VLF) and mine waste embankments. The shutdown and removal of the structures on the surface, including process facilities, will also be carried out as part of the closure activities.
The plan includes closure and post-closure activities. Closure refers to the period during which the final specifications of the closure design are met through activities such as chemical stabilization of VLF, improvements to surface water channels, physical stabilization of mine waste embankments, removal of selected infrastructure, re-grading of the site, and construction of access controls and safety berms. It is anticipated that the closure activities will last for several years after the termination of active mining and are necessary to achieve the objectives and criteria of the post-closure design.
The post-closure phase begins after the termination of construction and water management activities of the closure phase and will commence after the closure design specifications are met. During this phase, activities will be limited to site monitoring, site inspections, and all other activities necessary to comply with the established standards for water quality, such as the seasonal evaporation of any liquid of meteoric origin in the leach pad that does not comply with water quality standards. It is difficult to estimate the amount of time post-closure activities will take but it is anticipated that post-closure activities will last for 10 to 15 years. The current plan uses a post-closure period of 15 years.
OBJECTIVES OF THE CLOSURE PLAN
The main objectives for the Veladero closure are:
 
 	•	 	Meet or exceed Argentine regulations and commitments for the final closure of the Project.	
 
 	•	 	Comply with or exceed environmental agreements for the financing of the final closure.	
 
 	•	 	Protect the health and safety of the Veladero workforce during implementation of the closure plan and the health and safety of the communities after the closure by mitigating risks and hazards after closure in such a way as to prevent the risks and hazards from being more serious than they were before the development of Veladero.

Technical Report NI 43-101 – March 27, 2014	  	Page 20-4  	

			
	  	www.rpacan.com	

 	•	 	Propose long-term development on the site in order for its functions and values to coincide with those of the surrounding areas, ensuring that closure design and implementation comply with post-closure objectives concerning land use. For the purpose of planning, the functions and values of the area are considered to comprise visual (landscape), environmental (amount and quality of water, habitats and wildlife) and economic aspects (future mining potential).	
 
 	•	 	Protect the environment and promote public health and safety, rehabilitating, to the extent possible, the affected surfaces and water courses so that they can reach stability for future land uses which should be compatible with the ones that existed prior to the development of Veladero.	
 
 	•	 	Minimize the need for long-term maintenance and active care of the site during post-closure.	
SIMULTANEOUS REHABILITATION
The main activities of simultaneous rehabilitation that are to be carried out during the service life of the mine include the following:
 
 	•	 	General areas	
 
 	•	 	Road rehabilitation	
 
 	•	 	Recovery of vegas	
GENERAL AND ROAD REHABILITATION
MAGSA has committed to carry out rehabilitation in parallel whenever possible. This commitment entails maintaining the lowest level of surface alteration during the life of the project in order to minimize the rehabilitation activities at the end of the mine life. Road rehabilitation will be carried out as roads become unnecessary for future access to different sites. Road rehabilitation activities are due to begin in the middle of the mine life.
RECOVERY OF VEGAS
MAGSA has committed to study the development of vegas, i.e., wetlands in order to improve and potentially develop additional areas for vegas. This simultaneous rehabilitation program is developed with the aid of specialists to study the potential for regeneration and relocation of vegas through on site experiments.
REHABILITATION COSTS
Mine closure plans are reviewed and analyzed annually. Current cost estimates for closure at Veladero are approximately US$59 million.

23 ADJACENT PROPERTIES
Barrick’s Pascua Lama gold and silver project is located less than 10 km to the northwest of Veladero. The Pascua Lama project straddles the border between Argentina and Chile and its development has been lengthy and complicated for a number of reasons including the need to have bi-national support. As of EOY2013, Barrick had suspended construction on the project, and was in the process of putting the site on care and maintenance during the time of RPA’s Veladero site visit. Pascua Lama’s primary access route is the same all-weather access road used by Veladero.

25 INTERPRETATION AND CONCLUSIONS
Based on the site visit and subsequent review, RPA offers the following conclusions:
MINERAL RESOURCE ESTIMATION
 
 	•	 	The EOY2013 Measured and Indicated Mineral Resources, exclusive of Mineral Reserves, total 164.4 million tonnes averaging 0.68 g/t Au and 12.8 g/t Ag and contain 3.6 million ounces of gold and 67.9 million ounces of silver.	
 
 	•	 	The EOY2013 Inferred Mineral Resources total 27.9 million tonnes averaging 0.30 g/t Au and 12.9 g/t Ag and contain 269,000 ounces of gold and 11.6 million ounces of silver.	
 
 	•	 	Essentially all of the remaining resources and reserves are found in the Veladero area within the Filo Federico and Cuatro Esquinas zones.	
 
 	•	 	The resource estimate gold cut-off grades range from 0.20 g/t for ROM material from the Filo Federico pit Type 1 material to 0.48 g/t for Filo Federico pit Type 2 material, which requires crushing.	
 
 	•	 	Mineral Resource estimates have been prepared utilizing acceptable estimation methodologies. The classification of Measured, Indicated, and Inferred Resources conform to CIM (2010) definitions.	
 
 	•	 	The current drill hole database is reasonable for supporting a resource model for use in Mineral Resource and Mineral Reserve estimation.	
 
 	•	 	The methods and procedures utilized to gather geological, geotechnical, assaying, density, and other information are reasonable and meet generally accepted industry standards. Standard operating protocols are well documented and updated on a regular basis for most of the common tasks. The mine carries out regular comparisons with blast hole data, previous models, and production reconciliation results to calibrate and improve the resource modelling procedures.	
 
 	•	 	The resource model demonstrates a positive bias when reconciled against the grade control model in 2013 due mostly to new high grade mineralized structures defined by the blast holes that were generally not intersected in the exploration drill holes. Although finding unexpected high grade mineralization in the pit is certainly a very positive outcome for Veladero, it may be difficult to make significant adjustments to the resource model without new drilling data. It is unknown for how long this positive reconciliation will continue. RPA concurs with Barrick’s plan to us the recently completed structural interpretation along with new geostatistical and other strategies to improve the resource model in the areas where higher than expected grades were encountered.

Technical Report NI 43-101 – March 27, 2014	  	Page 25-1  	

			
	  	www.rpacan.com	

 	•	 	Exploration and development sampling and analysis programs use standard practices, providing generally reasonable results. The resulting data can effectively be used for the estimation of Mineral Resources and Mineral Reserves.	
 
 	•	 	Overall, RPA is of the opinion that MAGSA has done high quality work that exceeds industry practice.	
MINING AND MINERAL RESERVES
 
 	•	 	The EOY2013 Proven and Probable Reserves are estimated to be 186.6 million tonnes at 0.85 g/t Au and 14.8 g/t Ag, containing 5.1 million ounces of gold and 89 million ounces of silver.	
 
 	•	 	The Mineral Reserve estimates have been prepared utilizing acceptable estimation methodologies and the classification of Proven and Probable Reserves conform to CIM (2010) definitions.	
 
 	•	 	Recovery and cost estimates are based on actual operating data and engineering estimates.	
 
 	•	 	Economic analysis of the Veladero LOM plan generates a positive cash flow and, in RPA’s opinion, meets the requirements for statement of Mineral Reserves. In addition to the Mineral Reserves in the LOM plan, there are Mineral Resources that represent opportunities for the future.	
 
 	•	 	The economic pit limits are very sensitive to an increase in reserve gold price of 10%, while they are not very sensitive to a decrease in reserve gold price of 10%, indicating the current LOM plan is strong with potential for expansion in the future if market conditions were to stabilize or improve.	
PROCESS
 
 	•	 	The crushing circuit and conveyor circuit had lower than expected availability due to equipment maintenance issues. The ore is quite abrasive, resulting in frequent liner changes, which reduces availability. Measures are being implemented to deal with these issues.	
 
 	•	 	The overland conveyor has experienced more than desired downtime resulting in mine trucks having to be diverted to transfer leach pad material from the crushing plant.	
 
 	•	 	With the curtailment of mercury sales, long term storage will be required, and is being addressed.	
 
 	•	 	Senior supervision in the plant has been replaced in the last few months. It is anticipated that the new team will be effective in increasing operational availability.

ENVIRONMENTAL CONSIDERATIONS
 
 	•	 	Veladero has an Environmental Management Plan that is certified under the ISO 14001 standards. It is audited annually and was re-certified in 2013.	
 
 	•	 	In March 2013, as a result of an administrative investigation, the Ministry of Mines in the Province of San Juan issued a permit amendment restricting the amount of fresh water that can be used at the Project’s heap leach pad. Barrick expects the restrictions to be removed shortly, however, failure to obtain approvals in a timely manner will have an increasing impact on 2014 production. In RPA’s opinion, it is reasonable to assume that the current situation will be resolved in a timely manner, thus not impacting the current Mineral Resource and Mineral Reserve estimates.	
 
 	•	 	Veladero is certified by the International Cyanide Management Code. Re-certification occurs annually and Veladero was re-certified in May 2013.	
 
 	•	 	Mine closure plans are reviewed and analyzed annually. Current cost estimates for closure at Veladero are approximately US$59 million.

26 RECOMMENDATIONS
RPA makes the following recommendations:
GEOLOGY AND MINERAL RESOURCES
 
 	•	 	The resource modelling work is very good and no significant procedural changes are warranted. The resource model, however, significantly under-predicted the contained gold produced in 2013 due to unexpected high grade mineralization in the Filo Federico pit. RPA concurs with Barrick’s plans to use the recently completed structural interpretation along with new geostatistical and other strategies to improve the resource model in the areas where higher than expected grades were encountered.	
MINING AND MINERAL RESERVES
 
 	•	 	Maintain flexibility in the final pit design to allow potential for additional pit wall pushbacks if market conditions were to stabilize or improve.	
 
 	•	 	Review economic pit limit and unit operating cost sensitivity to reduced production rate targets.	
 
 	•	 	Analyze requirement for additional production drilling capacity to meet forecast production in the LOM plan.	
 
 	•	 	Consider creating grade groups for mineralized material dispatched to the waste rock facilities to increase future economic potential of this material.
