“In 2011, we continued to focus on delivering strong operating results leading to the generation of significant cash flow. This cash flow has allowed us to fully fund our growth, reward shareholders through increased dividends and accelerate capital spending to enhance our production growth profile. In the coming year, our focus on strong operating results leading to expected increases in cash flow will continue,” commented Peter Marrone, Chairman and Chief Executive Officer. “We are now looking beyond 2014 with an initial 1.75 million plus GEO sustainable production level. We are advancing projects to fill the project pipeline and to continue growth beyond what is already contemplated.”

(All amounts are expressed in United States dollars unless otherwise indicated.)

(1) Silver production is treated as a gold equivalent at a ratio of 50:1.

(2) By product cash costs are non-GAAP measures. A description of non-GAAP measures can be found at the end of this press release.

2011 PRELIMINARY OPERATING RESULTS

Production and costs for 2011 were within previously provided guidance. Production during Q4, 2011 was approximately 276,900 GEO, at costs consistent with guidance. For the full year ended December 31, 2011, total production for the Company was approximately 1.10 million GEO consisting of 915,513 ounces of gold and 9.3 million ounces of silver. Full year cash costs are estimated to be below $50 per GEO, below guidance levels.

PRODUCTION OUTLOOK 2012-2014

Production in 2012 is expected to be in the range of 1.2 – 1.3 million GEO. This will represent an increase from 2011 production of 13%, most of which will come from Mercedes as its production ramps up, and the Minera Florida expansion which will add to production starting end of January 2012. C1 Santa Luz and Ernesto / Pau a Pique are also expected to start production by the end of 2012.

Production in 2013 is expected to increase by 43% from 2011 levels to a range of 1.5 – 1.7 million GEO, most of which will come from a full year of production from C1 Santa Luz and Ernesto/Pau a Pique, and the start-up of Pilar and the Gualcamayo expansion.

Estimated production on a mine-by-mine basis for 2012-2013 is detailed below:

Silver production is expected to be consistent at between eight to nine million ounces in each of 2012 and 2013. Silver production is reported as a gold equivalent and included in the above forecasts and reported at a ratio of 50:1.

In late December 2011, the Company completed the feasibility study on the oxides at Suruca which supports average production of 49,000 gold ounces per year over an initial five years beginning in 2013. The Company is now evaluating the gold and copper production contribution to Chapada from Corpo Sul. Planned production for Chapada will decline in 2012 over 2011 levels, although will increase in terms of gold production in 2013 and in the years to follow, mostly as a result of the start-up of Suruca which is a recently discovered nearby oxide gold only ore body.

Planned production for 2014 is expected to be at a sustainable level of approximately 1.75 million GEO.

Opportunities for sustainable production of over 1.75 million GEO in 2014 and sustainability thereafter include the following:

—  Development plan for Chapada to incorporate Corpo Sul which is expected

    to primarily sustain current production grades and levels for both

    copper and gold.

—  Production at El Penon increasing to a sustainable 440,000 GEO per year

    as development work is completed at newly discovered ore bodies.

—  Full ramp up of Gualcamayo’s expansions to be completed mid-2013, which

    should increase sustainable production to over 200,000 gold ounces per

    year beginning in 2014.

—  Evaluation of milling higher grade ore at Gualcamayo subject to mineral

    resource increases into 2012 and 2013, in relation to which a scoping

    study is expected to be completed in mid-2012.

—  Development of higher grade areas at Jacobina increasing production to

    above 140,000 gold ounces per year beginning in 2014.

—  Increasing Mercedes production to a sustainable level of 140,000 GEO

    beginning in 2014 resulting mostly from a throughput increase to up to

    1,800 tonnes per day.

—  Increasing Pilar production to 140,000-150,000 gold ounces beginning in

    2014 mostly due to an increase in plant capacity and processing ore from

    Pilar and nearby Caiamar which is higher grade.

Current exploration and early development projects will potentially add to this production level and will be included in our guidance and forecasts once construction decisions have been made. These standalone projects include: Jeronimo, Agua Rica and Suyai.

CASH COSTS

Estimated cash costs for 2012 are forecasted to be below $250 per GEO. Cash costs are calculated after base metal by-product credits.

CAPITAL EXPENDITURES

Total development capital spent in 2011, not including capitalized exploration, is approximately $435 million, which is below previous guidance of $500 million. The capital amount of $65 million not spent in 2011 will now be spent in 2012. Sustaining capital spent in 2011 is approximately $265 million.

Development capital to be spent in 2012, including the $65 million carry forward from 2011 and excluding capitalized exploration, is expected to be $665 million. This includes amounts for new projects for which capital was not yet committed in 2011. These include:

—  Initial development capital for Jeronimo in anticipation of a

    construction decision expected in 2012. Jeronimo’s annual gold

    production is expected to be approximately 150,000 ounces per year, with

    production in the early years of approximately 190,000 ounces.

—  Initial development capital for various studies relating to Suyai,

    leading to the evaluation of Suyai as a high grade, low cost underground

    mine with off-site processing, tailings and waste facilities.

—  Development capital for Pampa Augusta Victoria (PAV) and other vein

    structures at El Penon which is expected to improve production and

    provide mining flexibility for a sustainable production level of at

    least 440,000 GEO per year and to increase mine life.

—  Development capital for Caiamar, which will contribute to production at

    Pilar thereby increasing production to a minimum of 140,000 gold ounces

    per year once in full production.

—  Development capital at higher grade ore bodies at Jacobina, allowing

    production to increase to above 140,000 gold ounces per year.

Development capital will decline into 2013 and the following years as the Company’s development projects are completed.

For 2012, sustaining capital is expected to be $340 million across all operations and is expected to decline after such development projects are completed in 2014. Sustaining capital per GEO will range from $190 to $240 per GEO from 2012 to 2014 declining to the lower end of the range in later years. Sustaining capital per GEO allocates a portion of sustaining capital to copper in proportion to revenue contribution.

The Company is also contemplating certain initiatives that will result in improved recoveries, reduced costs and/or mine life extension at various operations. These projects are currently being evaluated with final decisions still pending. The most significant impact projects are at El Penon, Chapada and Pilar.

EXPLORATION

The Company expects to spend approximately $125 million on exploration, a continuation of the successful 2011 program. Yamana’s 2012 exploration program will continue to focus on increasing mineral reserves and mineral resources with its near-mine and regional exploration programs, as well as continuing to explore greenfield targets. The Company’s mineral resource and mineral reserve estimates for 2011 are expected in late February 2012.

NON-GAAP MEASURES

The Company has included certain non-GAAP measures including “Co-product cash costs per gold equivalent ounce”, “Co-product cash costs per pound of copper”, “By-product cash costs per gold equivalent ounce”, “Adjusted Earnings or Loss and Adjusted Earnings or Loss per share” to supplement its financial statements, which are presented in accordance with International Financial Reporting Standards (“IFRS”). The term IFRS and generally accepted accounting principles (“GAAP”) are used interchangeably throughout this press release.

The Company believes that these measures, together with measures determined in accordance with IFRS, provide investors with an improved ability to evaluate the underlying performance of the Company. Non-GAAP measures do not have any standardized meaning prescribed under IFRS, 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 IFRS.

CO-PRODUCT AND BY-PRODUCT CASH COSTS

The Company has included cash costs per GEO and cash costs per pound of copper information because it understands that certain investors use this information to determine the Company’s ability to generate earnings and cash flows for use in investing and other activities. The Company believes that conventional measures of performance prepared in accordance with IFRS do not fully illustrate the ability of its operating mines to generate cash flows. The measures are not necessarily indicative of operating profit or cash flows from operations as determined under IFRS. Cash costs per GEO are determined in accordance with the Gold Institute’s Production Cost Standard and are calculated on a co-product and by-product basis. Cash costs on a co-product basis are computed by allocating operating cash costs separately to metals (gold and copper) 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. Cash costs per GEO and per pound of copper are calculated on a weighted average basis.
