TORONTO, Jan. 26 /CNW/ - YAMANA GOLD INC. (TSX: YRI; NYSE: AUY; LSE: YAU) today announced an update on its Agua Rica project in Argentina and a construction decision on its Ernesto/Pau-a-pique project in Brazil based on positive feasibility study results. All amounts are expressed in United States Dollars unless otherwise indicated.
"We have maintained our focus on consistency and reliability in operations and we have applied that focus and approach on our development stage projects," said Peter Marrone, Yamana's chairman and chief executive officer. "In 2009, we undertook a review of Agua Rica and Yamana is now able to further embrace this project as a potential significant future contributor to production. Our review of Agua Rica also demonstrates that the project should provide considerable value. We are now undertaking additional optimization initiatives, providing the potential for substantial additional upside to the project. We expect significant growth from our other development stage projects for which construction decisions have been made which now include Ernesto/Pau-a-pique. With our core operations, development stage projects and exploration focus, we believe that Yamana has a unique offering of growth, sustainability and value."
Agua Rica, Argentina
Yamana has continued to advance its Agua Rica project in Argentina. Agua Rica is a large scale copper, gold, silver and molybdenum porphyry deposit located in the mining-friendly province of Catamarca near the producing Alumbrera mine. A feasibility study was completed in 2006 and the environmental license was issued in 2009.
The Company has completed the first of several studies evaluating certain optimization initiatives over and above the evaluation of the project based on the 2006 feasibility study, all of which are expected to have a positive impact on the project. The optimization initiatives included the following:
<<>>
Total mineral resources as reported in Yamana's 2008 annual report is summarized as follows:
<< - Measured mineral resources of 64.1 million tonnes of ore with an average copper grade of 0.49% for a total of 700 million pounds of copper, and an average gold grade of 0.17 g/t for a total of 361,000 ounces of gold - Indicated mineral resources of 248.1 million tonnes of ore with an average copper grade of 0.40% for a total of 2.2 billion pounds of copper, and an average gold grade of 0.16 g/t for a total of 1.3 million ounces of gold - Inferred mineral resources of 651.0 million tonnes of ore with an average copper grade of 0.34% for a total of 4.9 billion pounds of copper, and an average gold grade of 0.12 g/t for a total of 2.5 million ounces of gold >>
Total mineral reserves as reported in Yamana's 2008 annual report is summarized as follows:
<< - Proven mineral reserves of 347.8 million tonnes of ore with an average copper grade of 0.57% for a total of 4.4 billion pounds of copper, and an average gold grade of 0.25 g/t for a total of 2.8 million ounces of gold - Probable mineral reserves of 449.9 million tonnes of ore with an average copper grade of 0.43% for a total of 4.3 billion pounds of copper, and an average gold grade of 0.21 g/t for a total of 3.0 million ounces of gold >>
The foregoing mineral reserve estimate was based on a copper price of $1.10 per pound and a gold price of $425 per ounce.
Based on the higher metal prices used in the optimization review, contained metal is expected to increase by at least five percent. An updated full mineral reserve estimate will be completed as part of the continued review of the project.
Based on the recently completed optimization study, Agua Rica is expected to produce approximately 12.5 million tonnes of copper/gold concentrate and 357,750 tonnes of molybdenum concentrate over a 26.5 year mine life. Estimated production and cash costs are summarized below:
<< ------------------------------------------------------------------------- Initial 10 Years LOM ---------------- --------- ------------------------------------------------------------------------- Average annual copper production 365M lbs 282M lbs By-product cash costs(1) per pound (net of Molybdenum credits)* $0.50 $0.53 ------------------------------------------------------------------------- Average annual gold equivalent production(2) 154,000 GEO 136,000 GEO Co-product cash costs(1) per gold equivalent ounce (GEO)* $370 $400 ------------------------------------------------------------------------- * excluding royalties ------------------------------------------------- (1) Co-product and by-product cash costs are non-GAAP measures. A definition is provided at the end of this press release. (2) Yamana treats silver as a gold equivalent. >>
By-product cash costs per pound of copper net of all by-product credits, including gold and silver, are estimated to be approximately $0.30 which makes Agua Rica one of the lowest cost copper/gold projects in the world.
As part of the new analysis, Yamana has also evaluated the capital expenditures assumed in the 2006 feasibility study and have concluded a reasonable estimate would be comparable at approximately $2.1 billion. Higher consumable costs and capital costs assumed in the update were mitigated by improvements in the assumed foreign exchange rates.
The new financial and economic model used by Yamana for its new base case analysis has assumed a copper price of $2.25 per pound and a gold price of $950 per ounce. On this basis, the assumed net present value would exceed $1.2 billion (based on a 7.5% discount rate), and the after-tax internal rate of return would be approximately 15%. Higher price assumptions of $3.25 per pound of copper and $1,050 per ounce of gold would increase the net present value by approximately $500 million and the after-tax internal rate of return would be approximately 24%. Yamana continues to evaluate the merits of a strategic partnership to derive value from Agua Rica. The value derived will be dependent on metal markets and general economic conditions.
This study now creates the new base case for the project. Yamana has concluded that this is an exceptional stand alone project offering significant value and currently has further optimization upside options being evaluated. They include:

A full update to the 2006 feasibility study, which would include the recently completed optimization initiatives, the additional initiatives under review and definitive mineral reserve and production estimates, will be provided as Yamana continues to work toward a formal construction decision expected before the end of 2011.
"The approach we have taken on evaluating Agua Rica is similar to Chapada in 2003," said Ludovico Costa, Yamana's president and chief operating officer. "In this project, a previous feasibility study done in 1998 was re-evaluated for improvements and new metal prices assumed which resulted in a positive feasibility study that has been upheld by subsequent results. We are pleased to have completed this first round of optimization initiatives at Agua Rica which confirm the exceptional value of the project and identified several initiatives that may add further value to the project. We believe that Agua Rica is a remarkable project offering robust returns and further value enhancement."
Ernesto/Pau-a-pique, Brazil
Yamana has made a formal decision for the construction of the Ernesto/Pau-a-pique project. The construction decision is based on positive feasibility study results and an expected upgrade in mineral resources as a result of deeper drilling of the ore body. The project has an initial mine life of approximately seven years with current mineral reserves of 710,000 ounces of gold included in measured and indicated mineral resources of 854,000 ounces of gold. The Company believes there is potential to extend the mine life as it continues efforts to upgrade mineral resource ounces to the proven and probable category and expand mineral resources at Ernesto as results demonstrate the deposit is open at depth and down dip.
The Company continues to progress more detailed engineering and an exploration tunnel to facilitate drilling in deeper areas where there are further resources. Yamana also continues to conduct pilot tests on metallurgy and recoveries. Permitting is underway and construction is expected to begin in mid-2010 with production commencing in late 2012.
Key parameters of the feasibility study include:
Mineral reserves and mineral resources:
<< ------------------------------------------------------------------------- Mineral Reserves* ------------------------------------------------------------------------- Proven Probable Proven & Probable ------------------------------------------------------------------------- Au Oz Au Oz Au Oz Tonnes (g/t) (Au) Tonnes (g/t) (Au) Tonnes (g/t) (Au) ------------------------------------------------------------------------- 2,279,000 3.86 283,000 4,827,000 2.75 427,000 7,106,000 3.11 710,000 ------------------------------------------------------------------------- ------------------------------------------------------------------------- Mineral Resources* ------------------------------------------------------------------------- Measured Indicated Measured & Indicated ------------------------------------------------------------------------- Au Oz Au Oz Au Oz Tonnes (g/t) (Au) Tonnes (g/t) (Au) Tonnes (g/t) (Au) ------------------------------------------------------------------------- 2,239,000 4.69 338,000 5,964,000 2.69 516,000 8,203,000 3.24 854,000 ------------------------------------------------------------------------- -------------------------- Inferred Mineral Resources -------------------------- Au Oz Tonnes (g/t) (Au) -------------------------- 4,400,000 1.79 256,000 -------------------------- * Mineral resources are inclusive of mineral reserves Capital cost: approximately $116 million Cash cost per ounce(1): $427 Average throughput: 1.0 million tonnes per year Average production (per year): approximately 100,000 ounces Initial mine life: 7 years After-tax IRR: approximately 31% ----------------------------------------------- (1) Co-product and by-product cash costs are non-GAAP measures. A definition is provided at the end of this press release. (2) Yamana treats silver as a gold equivalent. >>
The internal rate of return of approximately 31% is based on a gold price of $900 per ounce and a Brazilian Real of 1.8 in 2010 and 2.0 thereafter. The initial after-tax net present value is approximately $106 million and is based on a 5% discount rate. Total annual production is expected to average approximately 100,000 ounces of gold over the mine life, with the first two years of production averaging approximately 120,000 ounces further improving project economics. The payback period for the Ernesto/Pau-a-pique project is estimated at two years. Assuming a gold price of $1,100 per ounce the internal rate of return would increase substantially to 47% and the after-tax net present value with a 5% discount rate improves to $192 million. A sensitivity analysis on a 10% change of each variable on Ernesto/Pau-a-pique's after-tax IRR and NPV is provided below:
<< --------------------------------------------------------------------- Assumptions sensitivities IRR After-tax NPV --------------------------------------------------------------------- +0% change in assumptions 31% $106 million --------------------------------------------------------------------- +10% change in gold price 38% $145 million --------------------------------------------------------------------- +10% change in Brazilian Real 40% $137 million --------------------------------------------------------------------- >>
Expected capital costs of approximately $116 million account for the appreciation of the local currency as compared to the previous scoping study and the cost of acquiring the mine fleet which was not included in the original estimate as contractor mining had been assumed.
<< ------------------------------------------------- Initial capex estimate $86 million ------------------------------------------------- Impact of Brazilian Real + $12 million ------------------------------------------------- Acquisition of mine fleet + $18 million ------------------------------------------------- Updated capex estimate $116 million ------------------------------------------------- >>
Cash costs are estimated at $427 per ounce and are considered highly reliable compared to estimates in the original scoping study as they reflect Yamana's substantial operational experience in Brazil. The level of certainty of capital and operating costs has also increased with the further work completed.
<< ------------------------------------------------- ($ per ounce) ------------------------------------------------- Initial cash cost estimate Approx. $356 ------------------------------------------------- Impact of Brazilian Real +$50 ------------------------------------------------- Change in mine costs +$28 ------------------------------------------------- Change in plant costs -$20 ------------------------------------------------- Change in other opex +$13 ------------------------------------------------- Updated cash cost estimate Approx. $427 ------------------------------------------------- >>
The Ernesto/Pau-a-pique project is located in southwest Mato Grosso state, near Pontes e Lacerda in Brazil. The Pau-a-Pique deposit is approximately 62 kilometres by road south of the Ernesto deposit. The significant existing infrastructure including paved roadways supports the development of Ernesto/Pau-a-Pique as two operating mines with a common processing plant.
Ernesto/Pau-a-pique represents a modest cost, low capital and high return project contributing 8 to 10% to overall production. Significant potential for mineral resource upgrade serves as a platform for further exploration at the Guapore belt where Yamana has extensive exploration concessions.

Evandro Cintra, P.Geo., Senior Vice President, Technical Services for Yamana Gold Inc. has reviewed and confirmed the data contained within this news release and serves as the Qualified Person as defined in National Instrument 43-101.
About Yamana
Yamana is a Canadian-based gold producer with significant gold production, gold development stage properties, exploration properties, and land positions in Brazil, Argentina, Chile, Mexico and Colombia. The Company plans to continue to build on this base through existing operating mine expansions and throughput increases, the advancement of its exploration properties and by targeting other gold consolidation opportunities in the Americas.
NON-GAAP MEASURES
The Company believes that in addition to conventional measures prepared in accordance with Canadian GAAP, the Company and certain investors and analysts use certain other non-GAAP financial measures to evaluate the Company's performance including its ability to generate cash flow and profits from its operations. The Company has included certain non-GAAP measures throughout this document. When reference is made to "cash costs" in this document, the Company is referring to co-product cash costs. Cash costs on a co-product basis are computed by allocating operating cash costs separately to metals (copper and gold) based on an estimated or assumed ratio. Cash costs on a by-product basis are computed by deducting copper by product revenues from the calculation of cash costs of production per GEO. Non-GAAP measures do not have any standardized meaning prescribed under Canadian GAAP, and therefore they may not be comparable to similar measures employed by other companies. The data is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with Canadian GAAP.
