KEY STATISTICS

PRODUCTION SUMMARY – FINANCIAL AND OPERATING SUMMARY

Financial Results for the three months ended September 30, 2012

Revenues were $612 million in the third quarter compared with $555 million in the same quarter of 2011. Mine operating earnings were $279 million in the quarter, compared with $272 million in the third quarter of 2011. Higher revenues and mine operating earnings were mainly due to higher sales volume of gold from the production of the new Mercedes mine, which was under construction during the comparative period, partly offset by lower metal prices and lower volume of copper concentrate sales.

Revenues for the quarter were generated from the sale of 297,406 GEO and 37.1 million pounds of copper, excluding Alumbrera which is accounted for as an equity investment. This compares to production excluding Alumbrera of 266,351 GEO and 38.7 million pounds of copper in the third quarter of 2011.

Adjusted earnings were $178 million or $0.24 basic and diluted earnings per share in the third quarter of 2012, compared with $190 million or $0.26 per share in the same quarter of 2011. Lower adjusted earnings is attributed to lower metal prices, primarily copper and silver prices, partly offset by higher volume of gold sales and increased equity earnings from the Company’s interest in Alumbrera.

During the quarter, market fundamentals remained firm for gold and gold prices started to trend upward largely in reaction to the easing of monetary policy by most of the major economies. Compared with the third quarter of 2011, current quarter average realized gold price in 2012 was $1,680 per ounce versus $1,697 per ounce in 2011, current quarter average realized copper price was $3.54 per pound versus $3.98 per pound and current quarter average realized silver price was $30.76 per ounce compared to $37.52 per ounce in the third quarter of 2011. Although average realized prices for gold, copper and silver were lower than those in the third quarter of 2011, average realized prices for gold and silver trended upward from the second quarter of 2012, increased by 5% and 14%, respectively, consistent with market prices.

Net earnings for the quarter were $60 million or $0.08 per share on a basic and diluted basis, compared with net earnings of $116 million or basic and diluted earnings per share of $0.16 for the third quarter of 2011. Net earnings for the third quarter of 2012 were impacted by an increase in the Chilean tax rate, enacted in late September which affects the tax rates on both current and deferred income taxes. The Company has applied the new tax rate on all of its Chilean deferred income tax liabilities resulting in an adjustment to net earnings during the reporting period although deferred income taxes may never be paid unless the assets are sold through a direct asset sale. The additional taxes from the change in the Chilean tax rate may never be paid.

Depletion, depreciation and amortization (“DDA”) expense for the quarter was $101 million, an increase from $94 million in the third quarter of 2011. The impact in DDA is mainly driven by higher volume of gold sales and the additional DDA from the Mercedes mine, which was under construction during the comparative period in 2011.

Other expenses as an aggregate of general and administrative, exploration, other operating and net finance expenses were $94 million in the three months ended September 30, 2012, compared to $83 million in the third quarter of 2011. The increase in other expenses is detailed below.

General and Administrative expenses were $37 million compared to $28 million in 2011. The increase in administrative expenses was due to the expanded administration of the Company’s growing operations including the addition of the Mercedes mine.

Consistent with the Company’s exploration plans to pursue organic growth while continuing to build on its successful record of replacing and increasing mineral reserves and mineral resources, exploration expenses increased to $15 from $8 million incurred in the comparative quarter in 2011.

Other operating expenses were $27 million compared to $17 million in the comparative quarter of 2011 due to non-cash impairment losses recognized during the period, in particular the impairment losses on available-for-sale investment which accounted for $10 million.

Net finance expense was $15 million for the third quarter compared with net finance expense of $32 million in 2011. Significantly lower net finance expense in the current quarter, compared to the third quarter of 2011, was mainly due to lower unrealized exchange losses partially offset by interest expense on higher debt level and lower capitalization of borrowing cost as Mercedes completed commissioning in February. In the third quarter of 2011, higher unrealized exchange losses related to monetary assets and liabilities were recorded as a result of the increase in the value of the Brazilian and Chilean currencies versus the United States Dollar.

The Company recorded an income tax expense of $146 million for the quarter (2011: tax expense of $82 million) of which $84 million was related to the impact of increased Chilean tax rates on deferred income taxes. The potential impact of this Chilean tax rate change was disclosed and discussed in the Company’s second quarter report. As the charge is non-cash and relates to deferred tax balances recorded in prior years, it is added back to adjusted earnings. The current quarter income tax provision reflects a current income tax expense of $47 million (2011: tax expense $52 million) and a deferred income tax expense of $99 million (2011: deferred tax expense $30). Although taxes are accrued at a rate of 30% for accounting purposes, the adjusted tax rate for the third quarter of 2012 was 26%, in line with the comparative third quarter of 2011. The adjusted tax rate for the third quarter of 2012 excludes the effect of the Chilean tax increase on deferred income taxes.

Cash flows generated from operations before changes in non-cash working capital items for the quarter ended September 30, 2012 were $286 million compared to $331 million for the same period ended September 30, 2011. The decrease was due to lower earnings in the third quarter of 2012. Additionally, the Company did not receive any cash dividends from Minera Alumbrera in the third quarter of 2012 compared to $0.4 million received in the third quarter of 2011. Cash flows from operations after taking into effect changes in working capital items for the period ended September 30, 2012 were $363 million, compared to inflows of $342 million for the same period ended September 30, 2011. The increase was mainly attributed to the increase of trade payables and other payables due to timing of payments.

Equity earnings from associate were $21 million for the quarter compared with $9 million in the third quarter of 2011. Cash distributions from the Company’s equity investment in Alumbrera during the quarter were nil compared to $0.4 million in the third quarter of 2011.

Cash and cash equivalents as at September 30, 2012 were $400 million compared to $550 million as at December 31, 2011. The lower cash balance was due to the cash consideration paid upon the acquisition of Extorre in August 2012.

The Company has over $1.15 billion in available funds to continue to invest in future growth.

Financial Results for the nine months ended September 30, 2012

Revenues were $1.7 billion in the first nine months compared with $1.6 billion in the same period of 2011 mainly due to an increase of realized prices for gold and increased sales of gold partly offset by lower sales volume of concentrate, copper and silver, and lower prices for copper and silver. Mine operating earnings were $799 million, compared with $803 million in the first nine months of 2011.

Adjusted earnings were $497 million or $0.67 basic and diluted earnings per share in the first nine months of 2012, compared with $529 million or $0.71 per share in the same period of 2011. Lower adjusted earnings is mainly attributed to lower prices for copper and silver, lower volumes of copper and concentrate sold, partly offset by higher average realized gold prices and gold ounces sold during the period. Lower equity earnings from the Company’s investment in Alumbrera also affected net earnings for the period.

Average realized price of gold was $1,661 per ounce, consistent with market prices, compared with $1,532 per ounce for the same period in 2011. Average realized copper price was $3.62 per pound versus the average of $4.15 per pound, and average realized price for silver was $30.15 per ounce compared to $36.42 per ounce in the first nine months of 2011.

Net earnings for the first nine months were $273 million or $0.37 basic and $0.36 diluted earnings per share, compared with net earnings of $459 million or basic and diluted earnings per share of $0.62 for the same period of 2011. In addition to the items impacting adjusted earnings discussed above, net earnings were impacted by an increase in the Chilean tax rates, enacted in late September, which affected the tax rates on both current and deferred income taxes.

Cash flows generated from operations before changes in non-cash working capital items for the nine month period ended September 30, 2012 were $747 million compared to $946 million for the same period ended September 30, 2011. Cash flows from operations after taking into effect changes in working capital items for the period ended September 30, 2012 were $790 million, compared to inflows of $887 million for the same period ended September 30, 2011.

Equity earnings from associate were $33 million for the first nine months compared with $38 million in the same period in 2011. Cash distributions from the Company’s equity investment in Alumbrera during the period were nil compared to $27 million in the first nine months of 2011.

Operating Results for the three months ended September 30, 2012

Total production was a record 310,490 GEO for the third quarter, including the Company’s attributable production from the Alumbrera mine of 13,633 GEO and production during commissioning of the tailings re-treatment project at Minera Florida of 1,861 GEO, compared with production of 279,274 GEO for the quarter ended September 30, 2011. Commercial production for the quarter of 308,629 GEO was also a quarterly production record, representing an 11% quarter-to-quarter increase. The production increase was mainly due to the contribution from the Company’s new mine, Mercedes in Mexico and increased production from Fazenda Brasileiro. Production from all mines was in line with plan except for Minera Florida, where the ramp up of the tailings re-processing plant was delayed in part due to the installation of a zinc recovery plant which is expected to further improve the cost structure through additional zinc by-product credits. Build-up of ore stockpiles at Chapada, El Peñón, Jacobina and Gualcamayo continued to provide greater flexibility in respect to future production.

By-product cash costs were $201 per GEO, compared with $94 per GEO in the third quarter of 2011. By-product cash costs were impacted by lower copper sale credits as a result of lower market prices. The average market price for copper was 14% lower than that for the third quarter of 2011.

Co-product cash costs were $531 per GEO compared with $468 per GEO for the third quarter of 2011. Planned lower gold grades at certain mines and higher input costs during the period primarily impacted by-product and co-product cash costs.

Copper production for the third quarter was 39.4 million pounds from the Chapada mine, compared with 41.4 million pounds for the third quarter 2011. Chapada copper production was lower primarily as a result of expected lower copper grade and recovery rate offset by higher throughput compared with the third quarter of 2011. Additionally, 10.4 million pounds of copper produced from Alumbrera were attributable to the Company, compared with 9.5 million pounds for the quarter ended September 30, 2011. Total copper production for the third quarter was 49.8 million pounds, compared with 50.9 million pounds in the same quarter of 2011.

Co-product cash costs per pound of copper were $1.38 for the quarter from the Chapada mine, compared with $1.45 per pound for the third quarter in 2011. Co-product cash costs per pound of copper for the quarter including the Company’s interest in the Alumbrera mine were $1.49 per pound versus $1.48 per pound for the quarter ended September 30, 2011.

The Company anticipates average by-product cash costs for the year to be lower than $250 per GEO, in line with previous guidance. By-product cash costs are highly dependent on copper price assumptions. A downward trend in co-product cash costs is expected to result from the continued ramp up of production at Mercedes, additional lower cost production from the tailings re-treatment material at Minera Florida and the expected grade improvement during the fourth quarter at El Peñón and at Jacobina beginning in the fourth quarter.

OPERATING MINES

A summary of mine-by-mine operating results can be found on the final page of this press release.

Chapada, Brazil

Chapada produced a total of 33,610 GEO contained in concentrate in the third quarter of 2012 compared with 36,075 GEO contained in concentrate in the same quarter of 2011. Chapada copper production was 39.4 million pounds in the quarter compared with production of 41.4 million pounds of copper in the third quarter of 2011.

Production for the quarter was consistent with the mine plan, which indicated lower grades and recovery rates for 2012 relative to 2011. Production levels from Chapada will be less in 2012 compared to 2011 levels consistent with the mine plan, however, gold production is expected to increase late 2013 and in the years to follow, mostly as a result of the start up of the oxide gold operation at Suruca and the expected gold and copper production from Corpo Sul beginning in 2014.

By-product cash costs for the quarter were negative $1,659 per GEO compared with negative $2,045 per GEO for the same quarter in 2011. Lower by-product cash cost credits were due to lower copper sale credits as a result of lower market prices and lower sales volume of copper pounds. The favourable effects of higher tonnage mined and tonnage processed on by-product and co-product cash costs per GEO were partly offset by lower feed grades and lower recovery rates during the quarter compared to that of the third quarter of 2011. To reverse the trend of lower grades and lower recovery rates, a study to increase grind capacity has been started and a CIL project is planned for 2013.

Co-product cash costs were $341 per GEO in the third quarter, virtually unchanged from $329 per gold ounce in the same quarter of 2011. Co-product cash costs for copper were $1.38 per pound in the third quarter versus $1.45 per pound in the same quarter of 2011.

Chapada revenues for the quarter net of sales taxes and treatment and refining costs were $174 million (2011 – $149 million). Revenues included mark-to-market adjustments and final and provisional pricing settlements in the quarter of positive $6 million (2011 – negative $42 million).

In December 2011, the Company completed the feasibility study and basic engineering on the oxides at Suruca. The deposit will support an additional average production of 45,000-50,000 gold ounces per year to Chapada’s operations over an initial five years beginning in late 2013.

Drilling continued at Corpo Sul, a gold and copper deposit discovered in 2011 at the southwest end of the orebody of Chapada with mineral resources of higher average grade cores especially near the current Chapada pit. The additional drilling has further defined the geometry and grade continuity of Corpo Sul from the southwest limits of the 2011 mineral resources for an additional strike length of 2.9 kilometres. Mineralization and mineral resources have been traced along a combined strike length of almost 16 kilometres centered by the main Chapada pit. These new discoveries have led to the initiation of a pre-feasibility study, which is currently underway and expected to be completed by year end. Corpo Sul is expected to enhance throughput through the blending of this higher grade ore with ore from the main Chapada pit and, as its size and scale increases, it will be evaluated as a stand alone orebody.

The Company’s strategic plan is to ensure sustainable production from Chapada of 150,000 gold ounces and 135 million pounds of copper from 2013 for at least five years.

Jacobina, Brazil

Gold production at Jacobina was 30,028 ounces in the third quarter, compared with 31,567 ounces produced in the third quarter of 2011. The decrease in production in the third quarter compared to that of 2011, resulted from a decrease in feed grade and lower tonnage processed, partly offset by improved recoveries. Continued development of access to higher grade areas is expected to improve average ore grade beginning in the fourth quarter.

Cash costs were $768 per ounce for the third quarter compared with $654 per ounce in the third quarter of 2011. Cash costs were impacted by higher labour inflation and maintenance costs in addition to continued roof support improvements made during the quarter.

The Company continues to focus on upgrading the current mineral resources at Canavieiras and Morro do Vento and improving overall mineral reserve grade for the mine. Development of these high grade areas creates the opportunity for production to increase to approximately 140,000 ounces beginning in 2014.

Fazenda Brasileiro, Brazil

Production at Fazenda Brasileiro was 18,601 ounces of gold in the third quarter compared to 14,335 ounces of gold in the third quarter of 2011, representing a 30% quarter-over-quarter increase. The increased production was mainly due to higher gold grade and increased tonnage processed. Compared with the previous quarters of the year, the third quarter production also represents increases of 15% over the second quarter production and 32% above the first quarter production.

Cash costs for the third quarter were $803 per ounce, 15% lower than $940 per ounce for the same period in 2011. Increases in tonnage processed positively impacted cash costs and more than offset the effect of mining inflation. Compared with the previous quarters of the year, the third quarter per ounce cash costs also represent decreases of 3% from the second quarter and 23% from the first quarter cash costs.

The Fazenda Brasileiro mine was acquired in 2003 with two and a half years of mine life remaining based on known mineral reserves. The Company has been mining at Fazenda Brasileiro for nearly nine years. The mine continues to further outline exploration potential and mineral resource additions are expected in 2012.

Two new mineralization zones, CLX2 and Lagoa do Gato were discovered in 2009. The CLX2 zone is identified as having significant potential for high grade sources of ore for the mill. Both infill and extension drilling confirm the continuity of mineralization in both areas. The Company continues to develop the high grade mineral reserves at CLX2 with a focus on increasing mineral reserves and mineral resources. The Company is evaluating the possible extension of mine life.

El Peñón, Chile

El Peñón produced 118,457 GEO during the third quarter of 2012 compared to 120,627 GEO in the same quarter of 2011. Production for the quarter consisted of 83,092 ounces of gold and 1.8 million ounces of silver, compared with 76,347 ounces of gold and 2.2 million ounces of silver produced in the third quarter of 2011.

Production of gold increased by 9%, compared with the same quarter of 2011, mainly as a result of higher feed grade, while production of silver decreased by 20% due to lower feed grade and lower recovery rate. These variations in grade and recovery are consistent with the mine plan for 2012 and the result of the combination of ore from different veins and mines.

Cash costs were $422 per GEO in the third quarter, compared with $407 per GEO in the third quarter in 2011. Higher maintenance costs, increases in power costs, diesel and other consumables in addition to other mining cost inflation compared to that of the third quarter of 2011, contributed to higher per unit cash costs, which are expected to decrease as feed grades are expected to continue to improve for the balance of 2012, according to the mine plan.

Exploration has been ongoing for 20 years at El Peñón, which has a long track record of replacement of ounces mined. Exploration at Pampa Augusta Victoria (“PAV”) is being accelerated as part of the Company’s continuous exploration effort on high grade areas at El Peñón. This is expected to return significant near surface gold and silver values, improve production and provide mining flexibility for a sustainable production level of about 440,000 GEO per year and ultimately increase mine life. Development has commenced at PAV.

Minera Florida, Chile

Minera Florida produced a total of 22,339 GEO in the quarter, compared with 26,577 GEO in the third quarter of 2011. The expected lower production was mainly a result of the combined effect of lower gold and silver feed grades, lower gold recovery rate, and lower tonnage mined and processed. Grade variations are due to the combination of production areas included in the mine plan compared to that of the third quarter of 2011. Mine and plant production were also affected by weather, which extended its effects from the second quarter into the third quarter.

In addition, the mine produced 1,315 tonnes of zinc in the third quarter, compared with 2,389 tonnes of zinc produced in the third quarter of 2011. Zinc is accounted for as a by-product credit to cash costs.

Cash costs for the third quarter were $826 per GEO compared with $588 per GEO in the same quarter in 2011 primarily as a result of higher cost for power, increased cost in temporary mine services and labour inflation, the adverse effect of lower production on unit costs, and lower credit from sales of zinc as a result of lower production and lower prices for zinc.

The Company’s expansion project at Minera Florida is expected to increase annual production by approximately 40,000 GEO per year for five years through the re-treatment of tailings. The tailings re-treatment plant was completed in May and ramp up to design capacity was delayed in part due to the installation of a zinc recovery plant that was not initially contemplated. The zinc recovery plant is expected to further improve costs through the application of additional zinc by-product credits. Production from tailings re-treatment for 2012 is expected to be in the range of 12,000 to 16,000 GEO and ramp up to 40,000 GEO per year in 2013. Overall costs are expected to improve with the addition of tailings production given the lack of mining costs associated with the re-treatment of tailings. In subsequent periods, mine grade is expected to be consistent with plan and overall site performance augmented by ramping up the processing of relatively low cost historical tailings material.

The recently strengthened leadership team at the senior management level in Chile continues to focus on the operations in Chile and Mexico with the expansion at Minera Florida as their first priority.

Gualcamayo, Argentina

Gualcamayo produced 38,248 ounces of gold in the third quarter, representing a 2% increase, compared with 37,381 ounces produced in the third quarter of 2011. Higher production was mainly due to higher recoveries, in spite of lower feed grade. The grade for the third quarter was consistent with plan. Increased tonnage of ore mined reflects Gualcamayo’s continuous effort in stacking materials in preparation of transitioning to Phase III of the mine as part of the planned expansion. Recovery rate improved over the second quarter and the comparative quarter in 2011 as a result of the production from the new Valle Norte heap leach pad.

Cash costs were $669 per ounce in the quarter ended September 30, 2012 compared with $442 per ounce in the third quarter of 2011. Inflationary pressures on labour and consumable costs, lower grade and re-handling of waste costs along with increased maintenance to improve availability of equipment resulted in higher cash costs. Gualcamayo is an open pit operation along a mountain face and from time to time waste is removed and stored and then must be moved again once that ore has been accessed. This movement, or re-handling, of waste will cause costs to increase from time to time. This re-handling is also expected to have an impact on fourth quarter cost levels. The Company is evaluating how to reduce the re-handling of waste and has initiated a maintenance program in an effort to better contain costs. This is in addition to increased production through existing facilities, mainly from QDD Lower West, should reduce costs on a per ounce basis.

Underground development of QDD Lower West continues to advance and project completion remains on schedule. Full ramp-up of Gualcamayo’s expansions to be completed by mid-2013 are expected to increase sustainable production to over 200,000 gold ounces per year beginning in 2014.

A scoping study on the evaluation of milling higher grade ore at Gualcamayo, subject to mineral resource increases in 2012 and 2013, has commenced and is expected to be completed in the first half of 2013.

Mercedes, Mexico

Mercedes produced 33,713 GEO in the third quarter, representing increases of 17% over the second quarter production and 41% over the first quarter. Third quarter production consists of 31,497 ounces of gold and 0.1 million ounces of silver. Production at Mercedes has increased in consecutive quarters since the declaration of commercial production for Mercedes in February 2012.

Cash costs per GEO were $490 for the third quarter, 2% lower than the cash costs in the second quarter and 8% lower than the first quarter, representing decreases in consecutive quarters since the beginning of commercial production. Cash costs are expected to trend down as production continues to ramp up, averaging approximately $475 – $500 per GEO for the year.

Development continues at the Barrancas zone with the higher grade Lagunas Norte vein, one of the newest discoveries at the mine, which started production from sills in the third quarter. Development of the vein structure in the Barrancas zone was not included in the original mine plan and represents a significant opportunity to increase production. Infill drilling at Lupita is confirming the width and grades of mineralization and is expected to continue growth of the measured and indicated mineral resources that will extend mine life, maintain higher throughput and sustainable production levels.

Production is initially planned at an annual rate of 120,000 GEO per year although for 2012 the Company plans to produce approximately 105,000 GEO as the mine completes its ramp up. With the acceleration of underground development and plant modifications the Company expects production to increase to 125,000 – 135,000 GEO in 2013 with a target of 140,000 GEO thereafter.

Alumbrera, Argentina

The Company’s interest in the Alumbrera Mine is accounted for as an equity investment. The Company recorded earnings from its 12.5% interest in Alumbrera Mine of $21 million for the third quarter, compared with $9 million reported for the same quarter of 2011. Higher earnings were due to the resumption of export sales by Alumbrera in the second quarter to comply with a new resolution in respect of repatriation of net proceeds from export sales set forth by the Argentine Government. Subsequently, the Argentine Government amended its resolution enabling Alumbrera to resume export sales of concentrate in July and the backlog of sales is expected to be realized during the second half of 2012. The Company did not receive a cash distribution during the nine months ended September 30, 2012, compared with cash distributions of $0.4 million in the third quarter and $27 million for the nine month period ended September 30, 2011.

Attributable production from Alumbrera was 13,633 ounces of gold and 10.4 million pounds of copper for the quarter. This compares with attributable production of 12,712 ounces of gold and 9.5 million pounds of copper for the third quarter of 2011.

By-product cash costs per ounce of gold were negative $2,254 in the quarter ended September 30, 2012, compared with negative $1,216 in the third quarter of 2011. Co-product cash costs were $282 per ounce compared with $259 per ounce in the third quarter of 2011.

CONSTRUCTION AND DEVELOPMENT PROJECTS

Ernesto/Pau-a-Pique, Brazil

Physical completion is on schedule for end of the year. Ernesto/Pau-a-Pique commenced the commissioning phase, which will continue for the remainder of the year as will the process for obtaining the final operational permits. Commercial production is expected within 4-6 months. As of September 30, 2012, physical advancement continued and was approximately 96% complete. Mine development and electromechanical works continued as expected. Underground development at Pau-a-Pique continued to progress and reached a total length of more than 4,200 metres. Annual production is expected to be approximately 90,000-100,000 gold ounces.

C1 Santa Luz, Brazil

Construction is progressing to a planned physical completion by the end of 2012. Start up of operations is planned for early 2013 with commercial production expected within 4-6 months after start up. Water availability for C1 Santa Luz will come from a reservoir for which water is collected during the rainy season, which usually starts in November. Start up will depend on how quickly water will be accumulated in the reservoir. As of September 30, 2012, physical advancement of the project was over 90% complete. Civil works and electromechanical assembly continued as planned. Power line construction is expected to be completed in January 2013. Annual production is expected to be approximately 100,000 gold ounces with average annual production during the first two full years to exceed 130,000 gold ounces.

Pilar, Brazil

Construction progress is on schedule with commissioning and start up of production expected by mid-2013 with commercial production expected within 4-6 months of start up. As at September 30, 2012, mine and plant were advanced to approximately 66% completion. Civil works and electromechanical assembly continued as planned. Underground development at Pilar continued to progress and reached a total length of more than 8,000 metres and underground development at Caiamar has progressed more than 400 metres.

Annual production from the mine was originally estimated to be 120,000 ounces of gold. The project is being built with 30% additional capacity to that contemplated in the feasibility study in anticipation of significant mineral resource growth. Ore feed from Caiamar, a high-grade satellite deposit located 38 kilometres west of Pilar, is expected to contribute to production at Pilar thereby increasing production to a minimum of 140,000 gold ounces per year expected to begin as early as 2014. Mineral resource development and work on a feasibility study continued at Caiamar during the quarter. The ore from this deposit can be processed at Pilar with the higher grades offsetting the additional transportation costs.

Jeronimo, Chile

The Company continues to advance and evaluate additional organic projects, including Jeronimo and Suyai. At Jeronimo, the optimization studies, which supplement the feasibility study to further enhance the project economics and to create greater certainty on costs with the advanced engineering in progress, are expected to be delivered by the end of 2012. The pressure oxidation plant final process design is in progress. The benefit of reduced sulfuric acid consumption will be achieved with the insertion of a countercurrent decantation circuit. The review of the tailings disposal project, which relates to the thickening of tailings, has been completed; this tailings initiative is expected to reduce capital expenditures over the project life. The Company will continue discussions with its joint venture partner, Codelco (43% owner of the project), toward an objective of evaluating a construction decision.

EXPLORATION

The Company is committed to developing its future based on its exploration successes and organic growth with programs targeting mineral reserve growth and mineral resource discovery in addition to development projects and discoveries at existing operations.

The budget for the 2012 exploration program of $125 million will continue to focus on increasing the Company’s mineral reserves and mineral resources, accelerating the development of new discoveries such as Jordino and Maria Lazarus at Pilar, the extension of Pampa Augusta Victoria and definition of a new discovery at El Peñón, the expansion of high grade mineral resources at Jacobina and the development of several greenfield projects with the potential to be brought into the Company’s project pipeline, enhancing present and future asset values. Included in the program is $5 million, which is expected to be spent at Cerro Moro, an advanced exploration and development stage project obtained through the recent acquisition of Extorre.

The following summary highlights key updates from the exploration and development program at the Company since the end of the second quarter of 2012.

Cerro Moro, Argentina

On August 22, 2012, the Company acquired all of the issued and outstanding common shares of Extorre Gold Mines Limited that owned several exploration and development stage precious metals projects, the most advanced of which is the Cerro Moro project, a high grade gold and silver deposit with approximately 1.36 million ounces of gold equivalent indicated mineral resources and 1.05 million ounces of gold equivalent inferred mineral resources, located in the province of Santa Cruz in Argentina.

Evaluation of exploration and development plans is underway. The evaluations are expected to be completed by the end of 2012. The $5 million is to be spent in 2012 on this newly acquired property to increase and upgrade categories of mineral resources, with a focus on certainty in the definition of grade and size of the orebody. The recent granting of development permits by the Argentine government to a gold mining company for the building of a new mine in the province of Santa Cruz further demonstrates the mining friendly position of the provincial government.

Gualcamayo, Argentina

During the quarter, 13 diamond drill holes were completed at QDD Lower West. Year to date, the Company has completed 60 diamond drill holes totaling 13,496 metres. The drilling was completed to extend the southwest extension of the main QDD Lower West deposit and also to further delineate the Rodado breccia, which was discovered in 2011.

Pilar, Brazil

During the quarter diamond drilling was focused on infill drilling at the Jordino deposit. A total of 50 diamond drill holes were completed on the down dip portion of the Jordino deposit to upgrade the inferred mineral resource to the indicated mineral resource category and further increase confidence in the deeper parts of the deposit. For the remainder of the year, drilling will focus on the delineation of the Maria Lazarus deposit located 10 kilometres west of Jordino.

Chapada, Brazil

Exploration at Corpo Sul, the newly discovered mineralized zone located southwest of and adjacent to the main pit at Chapada, has completed 29,000 metres of diamond drilling out of a total planned program of 32,000 metres.

Results since the discovery of Corpo Sul, in 2011, have established the zone as a new porphyry system south of the main Chapada pit with grades in excess of expected grades being mined in future years at the operation. With continued drilling at 200 metre spacing, the Company has increased confidence in the continuity of the higher grades and the eventual increased size of Corpo Sul.

In the third quarter, 35 additional diamond drill holes have been completed on the southwest extension of Corpo Sul. The additional drilling has further defined the geometry and grade continuity of Corpo Sul from the southwest limits of the 2011 mineral resource. Results from the most recently received assays indicate all the high grade intersections are within 700 metres of the current Corpo Sul mineral resource and will extend the currently modeled mineral resource to the southwest.

The current drill results at Corpo Sul confirm the expansion of the mineralized zone and continue the recent exploration success at Chapada which commenced with Suruca in 2010 and Corpo Sul in 2011. Mineralization and mineral resources have now been traced along a combined strike length of almost 16 kilometres centered by the main Chapada pit.

These new discoveries have led to the initiation of a pre-feasibility study that is now underway, which will define the role of Suruca and Corpo Sul in the future production at Chapada. This study is expected to be completed by the end of 2012, and it is expected to include a new mineral resource at Corpo Sul using the current drilling information. Corpo Sul is expected to enhance throughput through the blending of these higher grade ore with ore from the main Chapada pit and as its size and scale increases it will be evaluated as a stand alone orebody.

In 2013, the Company expects to begin evaluating the area to the southeast of Corpo Sul and Chapada on targets that have already been identified, with the goal of unlocking further value at Chapada. Exploration success to date should facilitate targeted sustainable annual production levels of approximately 150,000 ounces of gold and 135 million pounds of copper from 2013 for at least five years. Continued exploration success is expected to extend this sustainable production level for a longer period within the overall mine life.

El Peñón, Chile

During the quarter, 105 diamond and reverse circulation drill holes were completed at El Peñón. The majority of the drilling was completed at Dorada West and the Elizabeth vein at Pampa Augusta Victoria. The new and additional drilling to be completed in the fourth quarter will allow for initial mineral resource estimates to be completed at both new vein zones by the end of the first quarter of 2013.

Dorada West is located immediately to the west of Dorada, approximately halfway between the Providencia and Dorada vein deposits. Drilling has outlined mineralization along a strike length of approximately 900 metres and a dip length of 150 metres. The deposit remains open to the south and down dip.

At Elizabeth drilling has outlined a vein structure that is very similar in appearance and grade to the Victoria vein located 400 metres to the west. However, the vein width at Elizabeth is typically narrower than Victoria with the average width being less than one metre.

Mercedes, Mexico

During the quarter, drilling totaled approximately 10,500 metres in 46 diamond drill holes. The drilling was completed at the Diluvio/Lupita area and the Rey de Oro vein zone.

At Diluvio/Lupita, drilling was completed to convert inferred mineral resource at Lupita to indicated mineral resource and to also explore the gap between the Diluvio and Lupita vein zones and try to establish a link between the two deposits. Although the drilling did establish a structural and mineralogical link between the two deposits, the grades of mineralization were uneconomic.

The Rey de Oro deposit lies on trend of the Klondike deposit approximately 200 metres further to the east-southeast. Drilling on 60 metre centers along strike and down dip has identified a wide zone (greater than 30 metres) of near surface, quartz veinlet stockworking with locally well developed quartz veins. The stockwork zone is strongly oxidized and select high grade intervals were previously mined by artisanal miners. Since the beginning of the year, 31 diamond drill holes have been completed at Rey de Oro.

Picacho, Mexico

The Company commenced its first drilling campaign at Picacho in July with drilling results expected before the end of 2012.

OUTLOOK AND STRATEGY

The Company is focused on operational reliability with a focus on increasing cash flows through containing costs and expanding margins, thereby maximizing shareholder value. The Company continues on a steady path of organic growth through expanding current, near term and in development production plans, developing new projects and advancing its exploration properties. The Company sometimes complements its growth strategy by adding properties and projects with high development potential and economic upside through strategic acquisitions.

Production in 2012 is expected to be in the range of 1.175 to 1.310 million GEO with a target level exceeding 1.2 million GEO. This will represent an increase from 2011 production of approximately 13%, most of which will come from Mercedes as production ramps up having completed commissioning in February 2012.

Production in 2013 is expected, to be in the range of 1.48 to 1.66 million GEO with a target level exceeding 1.5 million GEO. Almost all of the increase over 2012 will come from production from C1 Santa Luz and Ernesto/Pau-a-Pique, Mercedes being at full capacity for a full year, an increase in production at Minera Florida, the production coming from the expansion of Gualcamayo and Pilar, which we expect to start up by mid-year.

By 2014, production is targeted to be at a sustainable level of over 1.7 million GEO with a target of approximately 1.75 million GEO. Production of over 1.75 million GEO thereafter will depend upon construction decisions for other projects and assets held by the Company which are now being evaluated, the most advanced of which are Jeronimo, Cerro Moro, Agua Rica and Suyai.

The Company is contemplating certain initiatives that will result in improved recoveries, reduced costs and/or mine life extension at various operations. The objective of these initiatives is for cash flow sustainability and an increase in cash flow. The most significant potential impacts are at El Peñón, Chapada, Mercedes, Gualcamayo and Jacobina.

Cash costs are expected to remain below $250 per GEO for 2012. Cash costs are calculated after only base metal by-product credits.

Development capital expected to be spent in 2012 remains to be below $665 million as planned. This will decline in 2013 and the following years as the Company’s development projects are completed. Sustaining capital expenditures are expected to be $340 million in 2012 and while it will increase in aggregate as production increases it will decline on a per GEO basis as the production platform increases. The Company expects to spend approximately $125 million on exploration in 2012 with a continued focus on increasing mineral reserves and mineral resources with its near-mine and regional exploration programs, and exploration of greenfield targets.

In addition to over $1.15 billion of available cash and undrawn credit available at September 30, 2012, the Company expects robust cash flows from operations under the current and intermediate term pricing conditions for gold will enable the Company to fully fund its growth, reward shareholders through dividends and accelerate capital spending to enhance the Company’s production growth profile.
