The Company previously provided information on production and costs on an aggregate basis and by mine for Q2

2008 in its press release dated July 9, 2008. Further detail is available in Yamana's Q2 2008 Financial

Statements and Management's Discussion & Analysis. For complete financial disclosure and further detail about

the financial results and operations please see Yamana's Q2 2008 Financial Statements and Management's

Discussion & Analysis at www.yamana.com or www.sedar.com.



SECOND HALF 2008 GUIDANCE



Production for the second half of 2008 is expected to be 610,000 to 685,000 GEO. Production guidance for 2008

has been impacted by reduced expectations for Sao Francisco and Jacobina and increased expectations at El

Penon, Chapada and Gualcamayo which will be contributing more ounces and comparatively lower costs. At El

Penon, planned production remains on track to be at an annualized level of 500,000 GEO by the end of 2008. At

Chapada, production in the second half of the year is expected to exceed production in the first half.

Gualcamayo is expected to commence production by year end. Production for the balance of 2008 will in part also

depend on Alumbrera and Rossi, in which the Company has minority interests, establishing levels of production

that are not less than those reported for Q1. Both mines are expected to contribute a total of 22,000 GEO per

quarter. Copper production for 2008 is expected to be 190 to 200 million pounds, of which 155 to 160 million

pounds is expected to be from Chapada.



STRATEGIC OUTLOOK



Yamana has previously guided that its production range is expected to be 1.95 to 2.5 million GEO in 2012. Based

on existing reserves and resources, sustainable production of 1.95 million GEO is supported for and from 2012.

Assuming all projects are developed as planned and on schedule, the maximum production is expected to increase

to the higher end of the range. Based on existing reserves and resources and proposed increases at projects now

being evaluated, the Company has formed a strategic objective of 2.2 million GEO in 2012. As the Company

matures its projects, increases its reserves and resources and continues with feasibility work, the Company

will upgrade its strategic plan into a more formalized mine plan for each project under evaluation.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS: This news release contains certain "forward-looking

statements" within the meaning of Section 21E of the United States Securities Exchange Act of 1934, as amended

and "forward-looking information" under applicable Canadian securities laws. Except for statements of

historical fact relating to the company, information contained herein constitutes forward-looking statements,

including any information as to the Company's strategy, plant or future financial or operating performance.

Forward-looking statements are characterized by words such as "plan," "expect,", "budget", "target", "project,"

"intend," "believe," "anticipate", "estimate" and other similar words, or statements that certain events or

conditions "may" or "will" occur. Forward-looking statements are based on the opinions, assumptions and

estimates of management considered reasonable at the date the statements are made, and are inherently subject

to a variety of risks and uncertainties and other known and unknown factors that could cause actual events or

results to differ materially from those projected in the forward-looking statements.

These factors include possible variations in ore grade or recovery rates, fluctuating metal prices (such as

gold, copper, silver and zinc), currency exchange rates (such as Brazilian Real versus the US Dollar), changes

in the Company's hedging program, changes in accounting policies, changes in the Company's corporate resources,

changes in project parameters as plans continue to be refined, changes in project development and production

time frames, risk related to joint venture operations, the possibility of project cost overruns or

unanticipated costs and expenses, higher prices for fuel, steel, power, labour and other consumables

contributing to higher costs and general risks of the mining industry, failure of plant, equipment or processes

to operate as anticipated, unexpected changes in mine life, final pricing for concentrate sales, unanticipated

results of future studies, seasonality and unanticipated weather changes, as well as those risk factors

discussed or referred to in the Company's annual Management's Discussion and Analysis and Annual Information

Form filed with the securities regulatory authorities in all provinces of Canada and available at

www.sedar.com, and the Company's Annual Report on Form 40-F filed with the United States Securities and

Exchange Commission. Although the Company has attempted to identify important factors that could cause actual

actions, events or results to differ materially from those described in forward-looking statements, there may

be other factors that cause actions, events or results not to be anticipated, estimated or intended. There can

be no assurance that forward-looking statements will prove to be accurate, as actual results and future events

could differ materially from those anticipated in such statements. The Company undertakes no obligation to

update forward-looking statements if circumstances or management's estimates, assumptions or opinions should

change, except as required by applicable law. The reader is cautioned not to place undue reliance on forward-

looking statements. The forward-looking information contained herein is presently for the purpose of assisting

investors in understanding the Company's expected financial and operational performance and results as at and

for the periods ended on the dates presented in the Company's plans and objectives and may not be appropriate

for other purposes.



NON-GAAP MEASURES



The Company has included certain non-GAAP measures including cash cost per gold equivalent ounce ("GEO") data,

adjusted net earnings (loss) and adjusted net earnings (loss) per share to supplement its financial statements,

which are presented in accordance with Canadian GAAP. 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.



The Company has included cash cost per ounce information data because it understands that certain investors use

this information to determine the Company's ability to generate earnings and cash flow 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 flow. The measures

are not necessarily indicative of operating profit or cash flow from operations as determined under Canadian

GAAP. Cash costs are calculated on a by-product and co-product basis. Cash costs are determined in accordance

with the Gold Institute's Production Cost Standard. By-product cash costs are computed by deducting by-product

copper and zinc revenues from operating cash costs. Cash costs on a co-product basis are computed by allocating

operating cash costs separately to metals based on an estimated or assumed ratio. Where cost per ounce data is

computed by dividing GAAP operating cost components by ounces sold, the Company has provided a formal

reconciliation of these statistics in the Company's Management's Discussion and Analysis for the quarter ended

June 30, 2008 available at www.sedar.com or on the Company's website at www.yamana.com.



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 presentation of adjusted measures are

not meant to be a substitute for net earnings (loss) or net earnings (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) debt

repayment expense, (g) non-controlling interest and (h) internal transaction costs. 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.



The Company uses the financial measure "cash flow from operations before changes in non-cash working capital"

or "cash flow from operating activities before changes in non-cash working capital" to supplement its

consolidated financial statements. The presentation of cash flow from operations before changes in non-cash

working capital is not meant to be a substitute for cash flow from operations or cash flow from operating

activities presented in accordance with GAAP, but rather should be evaluated in conjunction with such GAAP

measures. Cash flow 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 flow from operations 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 flow 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 is a better indication of the Company's cash flow 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 flow.
