    "Our objective in 2009 was to create predictable and reliable operations 
while remaining committed to our core philosophy of sustainable production, 
operating in stable jurisdictions, growth and low cash costs," said Yamana's 
chairman and chief executive officer, Peter Marrone. "We have achieved our 
objective this year. This was a defining year for Yamana. We have sustainable 
production with our robust long life operational assets, we have growth with 
our well-defined development stage projects of which construction decisions 
have already been made for four, we have world class value enhancing projects 
in addition to significant exploration potential, and we have continued to 
deliver substantial cash flow growth which we expect to continue in 2010. As 
we begin this year, we remain committed to the core tenets of our Company as 
we prepare for our next new wave of growth."

officer. "We remained focused on maintaining industry low cash costs leading 
to our significant margin to the gold price. Further, we finished the year 
with a strong cash position and robust balance sheet." 
 
    Chapada, Brazil 
 
    Chapada produced 156,251 ounces of gold for the year, exceeding original 
production guidance of 140-155,000 ounces of gold. Plant optimizations began 
in the fourth quarter and are scheduled to increase throughput to up to 22 
million tonnes per year before 2012. 
 
    El Penon, Chile 
 
    El Penon produced 394,400 GEO for the year mining at a progressively 
higher rate and grade. In the fourth quarter, El Penon transitioned to 
owner-mining, which modestly and temporarily caused a decrease in production 
and increase in cash costs(1) which will carry over into the first quarter of 
2010 but is expected to improve production and going forward. Production in 
December at El Penon with the completion of the plant upgrade, although during 
this owner-mining transition period, was in excess of 44,000 GEO and was 
109,979 GEO for the fourth quarter. Production in the first quarter of 2010 is 
expected to be less than the fourth quarter of 2009 but higher than the first 
quarter in 2009. Production in 2010 is expected to ramp up quarter over 
quarter similar to trends seen in 2009. 
    Yamana is evaluating a new strategic plan for the optimization of El 
Penon to increase production from current levels with the objective of 
achieving a sustainable production level of 450,000 to 500,000 GEO. Yamana's 
intention is to begin at these levels in 2012 and going forward, subject to 
further evaluation. Contribution from the newly discovered high grade vein 
system, Pampa Augusta Victoria, will further support this objective. 
 
    Jacobina, Brazil 
 
    Development efforts in 2008 led to an improved performance in 2009 with 
production of 110,515 ounces of gold for the year, an increase of over 51 
percent from 2008. During the fourth quarter Jacobina began processing ore at 
6,000 tonnes per day, the level expected in 2010. 
    The Company remains focused on improving dilution and recovery as well as 
exploring, discovering and developing higher grade areas including 
Canavieiras. Exploration efforts will also be focused on the new discovery, 
Lagartixa. 
 
    Gualcamayo, Argentina 
 
    Gualcamayo continued to meet and exceed expectations in its first year of 
production. Production continued to ramp up in the fourth quarter increasing 
50 percent from the third quarter of 2009 with production for the full year of 
143,471 ounces exceeding original guidance of approximately 120,000 ounces. 
Cash costs for the year of $301 per ounce of gold were well below recent 
guidance of $350 per ounce of gold. 
 
    Minera Florida, Chile 
 
    Production for the year at Minera Florida was 91,877 per GEO, 
representing a 42 percent increase from the previous year as a result of the 
completed expansion in the first quarter of 2009. Development work continues 
to progress at the tailings project with production on track for early 2012. 
 
    Fazenda Brasileiro, Brazil 
 
    Production at Fazenda Brasileiro for the year was 76,413 ounces of gold. 
As Fazenda Brasileiro reaches the end of its known mine life based on mineral 
reserves, exploration efforts continue to focus on the two newly discovered 
areas, CLX(2) and Lagoa do Gato, which Yamana believes represent significant 
potential to increase the mine life.

    YEAR END MINERAL RESERVES AND MINERAL RESOURCES 
 
    Yamana today also announced its proven and probable mineral reserves and 
measured, indicated and inferred resources for the year ended December 31, 
2009. Yamana replaced mined ounces in 2009 with proven and probable mineral 
reserves for continuing operations of 17.6 million ounces of gold, which are 
consistent to levels in 2008. 
 
 
    Proven and probable gold mineral reserves increased in the following 
    areas: 
    -   710,000 ounces of gold at Ernesto/Pau-a-pique 
    -   264,000 ounces of gold at C1 Santa Luz 
    -   272,000 ounces of gold at Jacobina 
    -   281,000 ounces at El Penon. The recent discovery of a very high grade 
        vein, Pampa Augusta Victoria, represents the significant exploration 
        potential that remains at El Penon.

    Yamana continues to focus on exploration with a budget of $75 to $80 
million in 2010. The exploration program will continue to focus on numerous 
new areas of mineralization discovered in 2009 and on increasing mineral 
reserves and mineral resources while continuing with its near-mine exploration 
program and its efforts to look for new opportunities such as on the ground 
purchases elsewhere in the Americas. Yamana anticipates a substantial increase 
in mineral resources in 2010 as new mineral resource estimates are completed, 
including Salamanca, Caiamar and Suruca. 
 
 
    Key exploration events for 2010: 
    -   Mineral resource estimate at Salamanca, Gualcamayo: H1 2010 
    -   Updated mineral resource estimate at Pilar: mid 2010 
    -   Mineral resource estimate at Caiamar: H2 2010 
    -   Mineral resource estimate at Suruca, Chapada: End of 2010 
 
 
    OUTLOOK AND STRATEGY 
 
    Yamana remains committed to sustainability, growth, low cash costs and 
stability of jurisdictions. Its objective has been to create predictability 
and reliability in its operations with a sustainable production platform of 
approximately 1.1 million gold equivalent ounces. 
    The Company's outlook continues to focus on its core assets, preserving 
capital, maximizing cash balances and maintaining maximum flexibility across 
its various interests including its development stage and near development 
stage projects. The Company continues to be committed to prudent and 
disciplined growth and will continue to focus on improving the value and 
returns of its various projects. It will also continue to focus on containing 
costs and ensuring effective management of capital expenditures. 
    The Company's well defined development stage and exploration projects, in 
addition to further value enhancing opportunities, provide Yamana with a 
superior organic growth profile and value proposition. 
    Production from continuing operations is expected to be in the range of 
1,030,000 to 1,145,000 million GEO in 2010 and 1,045,000 to 1,150,000 GEO in 
2011 representing an overall increase of up to 12 percent from 2009. Growth is 
expected to ramp up substantially in 2012 to approximately 1.3 million GEO as 
four development stage projects including C1 Santa Luz, Mercedes, Minera 
Florida tailing project and Ernesto/Pau-a-pique, where construction decisions 
have already been made, are expected to begin production. By 2013, production 
is expected to reach the level of 1.5 million GEO, which represents a 46% 
increase in production from 2009. 
    Additional production growth is expected from development projects 
currently under evaluation such as QDD Lower West, Pilar and Caiamar which 
would bring the Company to a target production level of 1.7 million GEO. 
Exploration discoveries and robust value enhancing projects such as Agua Rica 
would contribute to longer term production growth. 
    The Company continues to evaluate the further expansion of its mines and 
development projects as follows: 
 
 
                                                                    Expected

    (i)    In the first two full years of production at C1 Santa Luz, average 
           annual production is expected to exceed 130,000 ounces and at 
           Ernesto/Pau-a-pique average annual production is expected to be 
           approximately 120,000 ounces which would accelerate pay-back. 
           Annual production over the life of mine for C1 Santa Luz is 
           expected to be 104,000 ounces of gold and 100,000 ounces of gold 
           at Ernesto/Pau-a-pique. 
    (ii)   In the first ten full years of production at Agua Rica, average 
           annual production is expected to be approximately 154,000 GEO and 
           365 million pounds of copper. Production over the life of mine is 
           expected to be 136,000 GEO and 282 million pounds of copper. 
 
 
    Yamana continues to increase the value of Agua Rica and 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 material positive impact on the project. 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 
the Company continues to work toward a formal construction decision expected 
before the end of 2011. 
    The Company remains focused on exploration through identifying and 
acquiring the best exploration properties in the Americas, developing a pool 
of talented geoscientists and replacing ounces at current operations.

    NON-GAAP MEASURES 
 
    The Company has included certain non-GAAP measures including "Cash costs 
per gold equivalent ounce", "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", "Cash flows from operations before changes in 
non-cash working capital" or "Cash flows from operating activities before 
changes in non-cash working capital" and "Gross margin" to supplement its 
financial statements, which are presented in accordance with Canadian GAAP. 
    The Company believes that these measures, together with measures 
determined in accordance with Canadian GAAP, 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 
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. 
 
    RECONCILIATION OF NON-GAAP MEASURES 
 
 
    Cash costs 
    --------------------- 
 
    The Company has included cash costs per GEO 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 Canadian GAAP 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 Canadian GAAP. 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 by-product 
basis are computed by deducting copper by-product revenues from the 
calculation of cash costs of production per GEO. 
 
    By-product Cash Costs Per Gold Equivalent Ounce ("GEO") 
    The following table provides a reconciliation of cost of sales per the 
financial statements and by-product cash costs per GEO:

    (i) Cash costs per GEO is calculated on a weighted average basis. 
 
    Adjusted Earnings or loss and Adjusted Earnings or loss per share 
    ----------------------------------------------------------------- 
 
    The Company uses the financial measures "Adjusted Earnings or Loss" and 
"Adjusted Earnings or Loss per share" to supplement information in its 
consolidated financial statements. The Company believes that in addition to 
conventional measures prepared in accordance with GAAP, the Company and 
certain investors and analysts use this information to evaluate the Company's 
performance. The presentation of adjusted measures are not meant to be a 
substitute for net earnings or loss or net earnings or loss per share 
presented in accordance with GAAP, but rather should be evaluated in 
conjunction with such GAAP measures. Adjusted Earnings or Loss and Adjusted 
Earnings or Loss per share are calculated as net earnings excluding (a) 
stock-based compensation, (b) foreign exchange (gains) losses, (c) unrealized 
(gains) losses on commodity derivatives, (d) impairment losses, (e) future 
income tax expense (recovery) on the translation of foreign currency 
inter-corporate debt, (f) write-down of investments and other assets and any 
other non-recurring adjustments. Non-recurring adjustments from unusual events 
or circumstances, such as the unprecedented volatility of copper prices in the 
fourth quarter of 2008, are reviewed from time to time based on materiality 
and the nature of the event or circumstance. Earnings adjustments reflect both 
continuing and discontinued operations. 
    The terms "Adjusted Earnings (Loss)" and "Adjusted Earnings (Loss) per 
share" do not have a standardized meaning prescribed by Canadian GAAP, and 
therefore the Company's definitions are unlikely to be comparable to similar 
measures presented by other companies. Management believes that the 
presentation of Adjusted Earnings or Loss and Adjusted Earnings or Loss per 
share provide useful information to investors because they exclude non-cash 
and other charges and are a better indication of the Company's profitability 
from operations. The items excluded from the computation of Adjusted Earnings 
or Loss and Adjusted Earnings or Loss per share, which are otherwise included 
in the determination of net earnings or loss and net earnings or loss per 
share prepared in accordance with Canadian GAAP, are items that the Company 
does not consider to be meaningful in evaluating the Company's past financial 
performance or the future prospects and may hinder a comparison of its 
period-to-period profitability. A reconciliation of Adjusted Earnings to net 
earnings as well as a discussion of the adjusting items is provided in Section 
4 "Overview of Financial Results" for both the yearly and quarterly 
reconciliations. 
 
 
    Cash flows from continuing operations before changes in non-cash working 
    ------------------------------------------------------------------------ 
    capital 
    ------- 
 
    The Company uses the financial measure "cash flows from operations before 
changes in non-cash working capital" or "cash flows from operating activities 
before changes in non-cash working capital" to supplement its consolidated 
financial statements. The presentation of cash flows from operations before 
changes in non-cash working capital is not meant to be a substitute for cash 
flows from operations or cash flows from operating activities presented in 
accordance with Canadian GAAP, but rather should be evaluated in conjunction 
with such Canadian GAAP measures. Cash flows from operations before changes in 
non-cash working capital excludes the non-cash movement from period-to-period 
in working capital items including accounts receivable, advances and deposits, 
inventory, accounts payable and accrued liabilities. 
    The terms "cash flows from operations before changes in non-cash working 
capital" or "cash flows from operating activities before changes in non-cash 
working capital" do not have a standardized meaning prescribed by Canadian 
GAAP, and therefore the Company's definitions are unlikely to be comparable to 
similar measures presented by other companies. The Company's management 
believes that the presentation of cash flows from operations before changes in 
non-cash working capital provides useful information to investors because it 
excludes the non-cash movement in working capital items and is a better 
indication of the Company's cash flows from operations and considered to be 
meaningful in evaluating the Company's past financial performance or the 
future prospects. The Company believes that conventional measure of 
performance prepared in accordance with Canadian GAAP does not fully 
illustrate the ability of its operating mines to generate cash flows. 
    The following table provides a reconciliation of cash flows from 
operating activities of continuing operations before changes in non-cash 
working capital:

    Cash flow per share 
    ------------------- 
 
    The Company uses the financial measure "cash flow per share"  The 
presentation of cash flow per share is not meant to be a substitute for cash 
flows from operations or cash flows from operating activities presented in 
accordance with Canadian GAAP, but rather should be evaluated in conjunction 
with such Canadian GAAP measures. "Cash flow per share" is calculated as "cash 
flows from operations after changes in non-cash working capital" divided by 
the weighted average number of shares outstanding and/or as "cash flows from 
operating activities before changes in non-cash working capital" (Non-GAAP 
measure) divided by the weighted average number of shares outstanding for the 
period. 
 
    The term "cash flow per share" does not have a standardized meaning 
prescribed by Canadian GAAP, and therefore the Company's definition is 
unlikely to be comparable to similar measures presented by other companies. 
The Company's management believes that the presentation of cash flow per share 
provides useful information to investors because it presents cash flows from 
operations on a per share basis and is useful information to investors in 
evaluating the Company's past financial performance or future prospects in its 
ability to generate cash flows.  The table below presents the calculation of 
cash flow per share:

    Gross margin 
    ------------ 
 
    The Company uses the financial measure "gross margin" to supplement its 
consolidated financial statements. The presentation of gross margin is not 
meant to be a substitute for net earnings presented in accordance with 
Canadian GAAP, but rather should be evaluated in conjunction with such 
Canadian GAAP measures. Gross margin represent the amount of revenues in 
excess of cost of sales. It may be expressed in terms of percentage of 
revenues, both in total amount or on a per GEO basis. 
    The terms "gross margin" does not have a standardized meaning prescribed 
by Canadian GAAP, and therefore the Company's definitions are unlikely to be 
comparable to similar measures presented by other companies. The Company's 
management believes that the presentation of gross margin provides useful 
information to investors because it excludes the non-cash operating cost items 
such as depreciation, depletion and amortization, accretion for asset 
retirement obligations and other common operating expenses, and considers this 
non-GAAP measure meaningful in evaluating the Company's past financial 
performance or the future prospects. The Company believes that conventional 
measure of performance prepared in accordance with Canadian GAAP does not 
fully illustrate the ability of its operating mines to generate cash flows.

    CAUTIONARY NOTE TO U.S. INVESTORS CONCERNING ESTIMATES OF MEASURED, 
INDICATED AND INFERRED MINERAL RESOURCES 
 
    This news release uses the terms "Measured", "Indicated" and "Inferred" 
Mineral Resources. United States investors are advised that while such terms 
are recognized and required by Canadian regulations, the United States 
Securities and Exchange Commission does not recognize them. "Inferred Mineral 
Resources" have a great amount of uncertainty as to their existence, and as to 
their economic and legal feasibility. It cannot be assumed that all or any 
part of an Inferred Mineral Resource will ever be upgraded to a higher 
category. Under Canadian rules, estimates of Inferred Mineral Resources may 
not form the basis of feasibility or other economic studies. United States 
investors are cautioned not to assume that all or any part of Measured or 
Indicated Mineral Resources will ever be converted into Mineral Reserves. 
United States investors are also cautioned not to assume that all or any part 
of an Inferred Mineral Resource exists, or is economically or legally 
mineable.
