2.           OVERVIEW OF FINANCIAL RESULTS

Net earnings for the quarter were $52.8 million compared to a loss for the comparative quarter ended June 30, 2006 of $58.3 million, representing an improvement of $111.1 million. Net earnings on a year to date basis were $80.2 million compared to a loss of $64.2 million for the six months ended June 30, 2006, representing an improvement of $144.4 million.  The increase in earnings is primarily due to commencement and ramp up of operations at the Chapada Mine since the beginning of this year.

Net earnings for the three and six months ended June 30, 2007 included certain non-cash and non-recurring charges in respect of stock-based compensation, foreign exchange gains or losses, unrealized losses on derivatives, loss on impairment of the Fazenda Nova Mine, non-production costs during business interruption (sill pillar failure costs) and a future income tax expense on foreign currency translation of inter corporate debt.

Adjusted earnings for these non-cash and non-recurring items was $85.2 million before income tax effects and $76.4 million after income tax effects for the quarter ended June 30, 2007 compared to $13.1 million for the comparative quarter.  The following table summarizes adjusted net earnings for the three and six month periods ended June 30, 2007 with comparative figures for the three and six month periods ended June 30, 2006:

Adjusted net earnings per share	$	0.22		$	0.05		$	0.35		$	0.06

Basic earnings per share were $0.15 and diluted earnings per share were $0.14 for the three months ended June 30, 2007.  For the six months ended June 30, 2007 basic earnings per share were $0.23 and diluted earnings per share were $0.22.  This compares to a basic and diluted loss per share of $0.21 and $0.27 for the comparative three and six month period ended June 30, 2006, respectively.

Earnings per share adjusted for certain non-cash and non-recurring items were $0.22 per share for the quarter. This compares to adjusted earnings per share of $0.05 for the comparative quarter, representing an increase of 340%.

Revenue for the quarter was $ 183.7 million, an increase of 27% over the preceding quarter and approximately 339% increase over the comparative quarter ended June 30, 2006. Revenue on a year to date basis was $328.8 million, an increase of 458% over the comparative six month period ended June 30, 2006.

Revenue for the quarter included sales of 120,022 ounces of gold and 31.7 million pounds of copper.  Revenue for the six months included sales of 242,723 ounces of gold and 55.6 million pounds of copper.

The Company’s average net realized gold price during the quarter was $660 per ounce, an increase of 5% from an average net realized price of $628 per ounce during the comparative quarter. This also compares to an average spot price of $668 per ounce for the quarter. On a year to date basis, the Company has realized an average net gold sale price of $653 per ounce, consistent with a spot price of $659 per ounce for the period.

Mine operating earnings were $ 106.7 million and $183.0 for the three and six month periods ended June 30, 2007, respectively. Mine operating earnings for the six months include earnings from the six mines.  Mine operating earnings for the comparative six month period were $16.7 million and included earnings from the Fazenda Brasileiro Mine, the Fazenda Nova Mine and the San Andrés Mine and Jacobina Mines as of the date of acquisition.

A total of 115,843 ounces were produced during the quarter.  On a year to date basis, the Company produced 236,450 ounces of gold. A total of 83,089 and 158,047 ounces of gold were produced by the Company’s mines during the comparative three and six month period ended June 30, 2006 including pro forma adjustments for pre-acquisition production from existing mines.

Additionally, production for the quarter and on a year to date basis included 31.5 million pounds of copper within 50,304 tonnes of concentrate and 59.0 million pounds of copper within 94,734 tonnes of concentrate, respectively.

Gold production for the balance of the year is expected to exceed 300,000 ounces of gold and up to 350,000 ounces of gold, largely depending on accelerating the production increase at the Jacobina Mine and processing planned higher grade material at the São Francisco Mine.  Copper production for the balance of the year is expected to exceed 70 million pounds of copper. The Company will assess its production expectations from time to time and as it continues to gain production experience from its mines recently placed into production and will update its production schedule accordingly.

Average cash costs for the quarter were $(434) per ounce compared to $332 per ounce for the comparative quarter ended June 30, 2006 and $(105) per ounce for the previous quarter ended March 31, 2007.  Average cash costs for the six months ended June 30, 2007 were $(267) per ounce compared to $325 for the comparative six month period ended June 30, 2006.  Cash costs for the three and six month periods for the Fazenda Nova and Jacobina mines are not reflective of ongoing operations as Fazenda Nova operations are being discontinued and Jacobina operations are gradually resuming after  the sill pillar failure in the first quarter. Average cash costs for the quarter excluding Fazenda Nova and Jacobina were $(557) per ounce.  On a co-product basis cash costs for the quarter were $0.72 per pound of copper and $305 per ounce of gold (excluding Fazenda Nova and Jacobina).

The Company recorded a non-recurring loss from non-production costs during business interruption of $10.4 million as a result of sill pillar failures at its Jacobina Mine during the six months ended June 30, 2007 of which $4.4 million was recognized during the second quarter. The Company has filed an insurance claim with respect to these business interruption losses. Any insurance recovery will be credited to net earnings in the period that the claim is settled with the insurance company.

Inventory as at June 30, 2007 was $62.3 million compared to $61.0 million as at March 31, 2007 and $51.3 million as at December 31, 2006.

Cash as at June 30, 2007 was $89.0 million compared to $69.8 million as at March 31, 2007 and $69.7 million as at December 31, 2006.  As at June 30 2007, the Company had accounts receivables in the amount of $72.1 million, compared to $49.5 million as at March 31, 2007 and $6.0 million as at December 31, 2006. This increase is due to concentrate receivables as at the quarter end from Chapada Mine sales and of ordinary course as production increases at the Chapada Mine and concentrate sales increase accordingly.

Working capital as at June 30, 2007 was $120.6 million compared to $97.4 million as at March 31, 2007 and $53.0 million as at December 31, 2006. The increase in working capital is primarily related to the start up of operations at the Chapada Mine.

Cash flow from operations before changes in non-cash working capital items was $90.9 million for the quarter compared to $15.1 million for the comparative quarter ended June 30, 2006. Cash flow from operations before changes in non-cash working capital items was $159.8 million for the six month period ended June 30, 2007 compared to $22.9 million for the comparative six month period ended June 30, 2006. The increase in cash flow from operations is primarily due to start-up of operations at the Chapada Mine.

General and administrative expenses were $10.7 million and $18.9 million for the three and six month periods ended June 30, 2007 compared to $5.3 million and $8.7 million for the comparative three and six month periods ended June 30, 2006. The increase in general and administrative expenses reflects the Company’s growth from operations and acquisitions and the growing infrastructure to support its production growth.

The Company recorded unrealized derivative losses of $19.9 million and $28.7 million for the quarter and six months ended June 30, 2007 consisting of mark-to-market gains and losses on commodity contracts, currency contracts and warrants held.

(v)  A cautionary note regarding non-GAAP measures follows below.

3.           NON-GAAP MEASURES

The Company has included certain non-GAAP Measures including cost per ounce data, adjusted net earnings and adjusted net earnings 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 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. Where cost per ounce data is computed by dividing GAAP operating cost components by ounces sold, the Company has not provided formal reconciliations of these statistics. Cash costs are determined in accordance with the Gold Institute’s Production Cost Standard. For the purposes of co-product cash cost calculation purposes, the Company assumes that operating costs are attributable to copper and gold on a 70/30 split. The attributable costs will vary from time to time and would be influenced by a number of factors including current market terms for treatment and refining costs and customer mix.  Cost of sales under Canadian GAAP and cash costs are reconciled by the following: non-cash movements in net working capital items and provisions for losses on inventory.

The Company uses the financial measures “adjusted net earnings” and “adjusted net earnings per share” to supplement its consolidated financial statements. The presentation of adjusted measures are not meant to be a substitute for net earnings or net earnings per share presented in accordance with GAAP, but rather should be evaluated in conjunction with such GAAP measures. Adjusted net earnings and adjusted net earnings per share are calculated as net earnings excluding (a) stock based compensation, (b) foreign exchange loss (gain), (c) future income tax expense on the translation of foreign currency inter corporate debt, (d) unrealized losses on derivatives, (e) impairment losses, (f) non-production costs during business interruption and (g) debt repayment expense. The terms “adjusted net earnings” and “adjusted net earnings 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. The Company’s management believes that the presentation of adjusted net earnings and adjusted net earnings per share provide useful information to investors because they exclude non-cash charges and are a better indication of the Company’s profitability from operations. The items excluded from the computation of adjusted net earnings and adjusted net earnings per share, which are otherwise included in the determination of net earnings (loss) and net earnings (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.

4.           BUSINESS ACQUISITIONS

Subsequent to the period end, the Company signed a definitive business combination agreement with Northern Orion Resources Inc. (“Northern Orion”) whereby the Company will acquire all of the issued and outstanding securities of Northern Orion on the basis of 0.543 of a Yamana share for each Northern Orion share.  Concurrently, the Company filed a formal offer for all of the outstanding common shares of Meridian Gold Inc. (“Meridian”).  The offer to Meridian shareholders entitles shareholders to receive 2.235 Yamana common shares plus C$3.15 in cash for each Meridian common share tendered and taken up by the Company. The offer will remain open until August 27, 2007, unless it is withdrawn or extended by the Company.

The premium to Northern Orion shareholders was approximately 28.4% based on the respective average closing prices for Yamana shares and Northern Orion shares for the 20 trading days on the TSX immediately preceding the June 27, 2007 announcement date.

The premium to Meridian shareholders was approximately 24.6% based on the respective average closing prices for Yamana and Meridian shares for the 20 trading days on the TSX immediately preceding the June 27, 2007 announcement date.

The Northern Orion transaction is subject to customary conditions including receipt of all requisite third party and regulatory approvals and consents, court approval and approval by shareholders of Northern Orion.  It is also conditional on at least 66 2/3% of the fully diluted outstanding Meridian common shares having been tendered to the Yamana offer.  The Northern Orion shareholder meeting to consider the business combination is currently scheduled for August 22, 2007, approximately five days prior to the expiry of Yamana’s offer to Meridian shareholders.

As part of the Northern Orion transaction, Northern Orion has agreed to enter into a definitive loan agreement with the Company for an amount of $200 million bearing interest at LIBOR plus 2%, repayable on the earlier of 12 months from the initial drawdown and 30 days following the acquisition by the Company of 100% of the fully diluted issued and outstanding shares of Meridian.  The first drawdown under the loan is conditional upon at least 66⅔% of the fully diluted issued and outstanding shares of Meridian having been tendered, and not withdrawn, to the offer.  The loan is not conditional upon the completion of the Northern Orion Transaction, and will not terminate in the event the termination of the Northern Orion Agreement, except in the case of a material breach of covenants by the Company and provided that another acquisition proposal for Northern Orion has not been made.

To complete the Meridian offer and the Northern Orion transaction, Yamana will issue approximately 309.8 million new common shares (226.1 million and 83.7 million common shares to Meridian and Northern Orion shareholders, respectively) and pay cash consideration of approximately $305 million (C$3.15 per share) to Meridian shareholders.  The cash consideration will be funded from the Northern Orion $200 million loan, internally generated cash and/or the Company’s existing $300 million revolving line of credit facility.  On an issued basis, the pro rata shareholdings of the combined company are anticipated to be: 53.4% existing Yamana shareholders, 34.0% existing Meridian shareholders and 12.6% existing Northern Orion shareholders.

The Company believes that the proposed business combination presents an opportunity to create a stronger cash flow generating gold mining company.

Commercial production was declared at the Chapada Mine ahead of schedule on February 11, 2007.

The original design and operational results to date show the promise of expanding mill throughput to over 16 million tonnes per year of mill feed. The Company expects to optimize the mill and increase throughput during the remainder of the year.  Quarterly ore production of 5.2 million tonnes annualized represents an annualized production rate of over 20 million tonnes which is higher than design plant capacity. The vertimill commenced operation in mid April. Combined with refinements to the ore grinding size, selection of reagents and management of the circulating load, it is anticipated that recovery rates will continue to increase during the balance of the year. Recovery rates for the second improved relative to the first quarter for both gold and copper.

Chapada produced 50,304 tonnes of concentrate in the second quarter.  For the third and fourth quarter concentrate production is forecast to be approximately 60,000 tonnes per quarter.  On a year to date basis it produced 94,734 tonnes of concentrate. Concentrate production increased by 13% from the first quarter and is expected to rise further for the remainder of the year.

Gold contained in concentrate production was 44,027 ounces for the quarter at cash costs after by-product credit of $(1,789) per ounce. This compares to gold contained in concentrate production of 38,954 ounces for the first quarter at cash costs of $(1,077) per ounce.

Copper contained in concentrate revenue is applied as a by-product credit in the determination of cash costs per ounce of gold produced. On a co-product basis cash costs at Chapada during the quarter were approximately $0.72 per pound of copper and $209 per ounce of gold.  Total gold contained in concentrate produced for the six months was 82,981 ounces at cash costs of $(1,455) per ounce after by-product credits.  The Company measures cash costs based on the aggregate of all treatment, refining and transportation costs incurred for all copper and gold sold during the quarter rather than only costs attributed to ounces of gold and pounds of copper produced during the quarter.

Total revenue for the quarter net of sales taxes, treatment and refining costs during the quarter was $135.9 million and $223.8 million on a year to date basis. Associated transportation costs were approximately $9.2 million and $15.9 million for the respective periods. As at June 30, 2007 the Company had receivables in the amount of $65.5 million in respect of concentrate sales. Increases in second quarter revenues due to final pricing adjustments on first quarter sales were $2.0 million  As at June 30, 2007, revenues included 40.3 million pounds of copper recorded at $3.38 per pound that were still subject to final pricing adjustments.

Ore grades for the second quarter (gold - 0.54 g/t; copper – 0.51%) were fairly consistent with that of the first quarter (gold – 0.57 g/t; copper – 0.47%).  Improvements in throughput and recoveries are expected for the balance of the year.

A total of 5.2 million tonnes of ore were mined at average costs of $1.54 per tonne of ore during the quarter, representing an increase of 45% in tonnes mined over the first quarter and a decrease in mining costs per tonne of 22% over the first quarter.

Mine operating earnings for the quarter from the Chapada Mine were $100.7 million, making it the Company’s most profitable mine.  Mine operating earnings for the six months ended June 30, 2007 were $167.4 million.  Waste removal has now been contracted out and 18 Randan trucks are being redeployed at other mines as part of a cost reduction and efficiency program.  There were no mine operating earnings for the comparative periods from the Chapada Mine as the mine was still under construction in 2006.

The Company has completed a scoping study to evaluate the potential of a pyrite recovery circuit to roast pyrite to produce sulphuric acid for the fertilizer and mining industry. The final feasibility report is expected by the end of 2007.  This initiative would provide an additional source of revenue and further increase copper and gold recovery rates.

A total of 24,988 ounces of gold were produced from the São Francisco Mine during the quarter. This compares to production of 31,261 ounces of gold during the first quarter of 2007 for total production of 56,249 ounces for the year. There was no production from the São Francisco Mine for the comparative quarter ended June 30, 2006 as the mine was under construction with commercial production declared August 1, 2006.

Production at São Francisco was lower than previously forecast due to the fact that material which had previously been considered waste turned out to be mineralized and thus was put on the leach pads. While this means that production in the short term is lower it also means that total ore reserves are higher thus extending the mine life. It also accounts for costs being higher than previously forecast.

Average cash costs per ounce for the quarter were $340 per ounce, an increase of    3.7% from the quarter ended March 31, 2007. The increase in cash costs were a result of mining more dump leach ore during the quarter compared to that of the quarter ended March 31, 2007.

In March 2007, a currency hedge was put in place to manage the Company’s exposure to increases in costs at the São Francisco Mine due to fluctuations in the R$-US$exchange rate. This hedge continues to help improve cash costs and will provide protection against a strengthening Brazilian Real.

The average ore grade for the quarter was 0.52 g/t which is consistent with that of the first quarter.

Mine operating earnings for the quarter were $5.1 million compared to $5.8 million for the quarter ended March 31, 2007. Revenue for the quarter amounted to $16.8 million from the sale of 25,622 ounces of gold. This compares to revenue of $22.4 million from a total of 34,880 ounces sold during the first quarter.

Operations at São Francisco subsequent to the second quarter will begin to mine a higher percentage of the higher grade material and production and cash costs are expected to improve over the balance of the year.  Additional ramp access to the open pit has been created in order to reduce haulage costs.  Further, waste removal is now under contract to reduce waste removal costs and allow the Company to concentrate on operations and grade control.  Improvements in sampling procedures are also expected to reduce dilution of higher grade material.

(i) Includes production statistics from the date of acquisition of April 15, 2006

A total of 11,447 ounces of gold was produced at the Jacobina Mine during the second quarter.  Production at Jacobina resumed on a gradual basis during the second quarter following implementation of additional safety protocols and recommendations of rock mechanics advisers after certain sill pillar failures in historically mined areas earlier this year.  Production is expected to increase in the third quarter and further in the fourth quarter.   As part of a cost reduction initiative new mining equipment has been received after the quarter end.  Production from the Jacobina Mine for the comparative quarter ended June 30, 2006 was 22,333 ounces of gold at an average cash cost of $331 per ounce. Production for the six months ended June 30, 2006 totaled 18,524 ounces of gold.

Engineering and construction is underway and on track to increase the throughput capacity to 6,500 tonnes per day by the first quarter of 2008 and to 8,500 tonnes per day by the end of 2008.  Current forecast production for 2008 is 150,000 to 160,000 ounces with production of 200,000 ounces targeted for 2009.  Production for the second half 2007 is estimated at 50,000 ounces.

It is expected that production at Jacobina will be sustained at a rate of over 200,000 ounces per year after 2009 and, while this is largely dependant on upgrading the large indicated and inferred resources to reserves over the coming years, the resource base is considered sufficient for sustained production at this level from 2009 onward.

As part of the expansion strategy and upgrading of resources to reserves, underground mine development activities continued to progress at Canavieiras and at Morro do Vento Extension where most of the resource upgrade is expected.

The Company recorded a loss due to non-production costs for business interruption of $10.5 million during the six month period ended June 30, 2007 comprised of overheads and remediation costs associated with the sill pillar failure. Of this amount $4.4 million was recognized during the second quarter. The Company has filed an insurance claim in respect to these costs.  The insurance recovery will be credited to net earnings in the period that the claim is settled with the insurance company.

Cash costs for the quarter were $448 per ounce and for the six months were $456 per ounce.  These costs are not considered representative of full operations at Jacobina.  Furthermore, these cash costs do not include the loss due to non-production costs during business interruption nor any potential proceeds from the insurance claim.

The Company recognized a mine operating loss for the quarter of $3.3 million and a mine operating loss of $3.2 million on a year to date basis.   The loss for the quarter resulted predominately in a write-down of inventory during the quarter.

GUALCAMAYO PROJECT

During the quarter the Company completed the permitting application process for Gualcamayo and continued the feasibility study relating to the main open pit deposit at Gualcamayo. Both the permit and feasibility study are now pending.  The Company expects start up of operations at Gualcamayo in mid 2008.

The company has spent $15.6 million for the six months in feasibility, fixed assets and pre-construction work in respect to Gualcamayo including contracting for engineering services, purchase of mine equipment and construction of the ore pass.  A total of $9.8 million was spent during the second quarter.

The Company completed an updated resource for the Quebrada Del Diablo (“QDD”) area in September 2006, which outlined 2.1 million ounces of measured and indicated resources. The QDD area will form the basis of the first phase of the feasibility study. The Amelia Ines/Magdalena deposit is located 800 metres to 1,200 metres west of the QDD zone. A feasibility study for this area will be completed in the Fall following a scoping study which will be delivered along with the QDD feasibility. As the ore from these deposits is significantly higher grade than QDD, the Company is studying the potential of mining and processing this material in the second year of operation for at least six years. A further reserve/resource determination of QDD Lower West is expected by the end of the year in order to evaluate the potential for underground operations in addition to the open pit operation.

During 2006, the Company discovered a high-grade, multi-metre wide zone below QDD called the QDD Lower West Zone. This zone is currently being accessed by an exploration decline so that bulk sampling and delineation/exploration drilling can be completed. The metallurgical tests and resource estimate will be used to complete a Preliminary Economic Evaluation (PEE) during the fourth quarter of 2007 with a feasibility study to follow early in 2008. Currently the Company is studying the potential for mining and processing the higher grade material in Year 3 of the mine life.

The Company is targeting to production of more than 200,000 ounces of gold per year over a mine life of at least 10 years.

(i) Includes production statistics from the date of acquisition of February 28, 2006

A total of 13,941 ounces of gold were produced during the quarter. This compared to 16,952 ounces produced during the quarter ended March 31, 2007 and 17,082 ounces for the comparative quarter ended June 30, 2006.  On a year to date basis, the San Andrés Mine produced 30,893 ounces of gold.

A total of   0.8 million tonnes of ore were mined during the second quarter.  This compares to 1.0 million tonnes of ore mined during the first quarter.

Average cash costs for the quarter were $391 per ounce, an increase of 8.9% from average cash costs of $359 per ounce during the previous quarter ended March 31, 2007.  Year to date cash costs averaged $373 per ounce.

The average ore grade for the second quarter of 0.58 g/t was consistent with that of the first quarter. Ore grade is expected to return to higher levels during the third quarter.

The average mine recovery rate during the quarter increased from 88.4% during the first quarter to 94.0% during the second quarter 2007.

Operating earnings for the quarter were $3.2 million. This compares to $4.5 million for the previous quarter ended March 31, 2007. Mine operating earnings for the comparative quarter ended June 30, 2006 were $4.4 million.  Operating earnings for the six months were $7.7 million.

Revenue for the quarter was $9.8 million from the sale of 14,826 ounces of gold.

There is an indicated resource of 790,000 contained ounces (40.6 million tonnes at 0.61 g/t) outside of the current pit limits.  This resource was outlined as a result of drilling efforts following the acquisition of San Andrés in 2006.  The Company plans to complete metallurgical test-work and a study to determine the economics and feasibility of employing dump leaching to mine this material. This has the potential to significantly increasing the mine life and increasing annual production. The Company has applied for horizontal leach pad permit which would add five years to the mine life.  The permit is expected during the third quarter of 2007.  Planned production would increase to over 100,000 ounces per year for approximately ten years.

The Fazenda Brasileiro Mine was originally acquired in August 2003 with 2.5 years of initial estimated remaining reserve life. The objective for the Fazenda Brasileiro Mine is to add resources and convert existing resources into reserves thereby increasing the life of the mine.

Current reserve and resource estimates support an additional 4 to 6 years of mine life at production levels of approximately 80,000 ounces per year. Fazenda Brasileiro has a history of more than replacing ounces mined.

A total of 19,060 ounces of gold were produced during the second quarter. This compared to 19,658 ounces produced during the comparative quarter ended June 30, 2006 and 22,317 ounces produced during the first quarter 2007.  Production at the Fazenda Brasileiro Mine will vary from quarter to quarter and July is representative of this with production in July of 9,300 ounces.

Average cash costs for the quarter were $418 per ounce, an increase from the previous quarter.  Cash costs are expected to decline in subsequent quarters with production increases.

Lower production and higher cash costs are attributed to a 16% decrease in ore grade from 2.93 g/t during the first quarter 2007 to 2.47 g/t during the second quarter due to dilution. Fazenda Brasileiro Mine will vary from period to period.  Grades recovered to greater than 3.0 g/t for the month of  July.  The average ore grade for the comparative quarter ended June 30, 2006 was 2.80 g/t.

Tonnes mined and milled increased from the first quarter to the second quarter by 7.0% and 1.0% respectively.

The average mine recovery rate during the second quarter was 93.9% which is consistent with that of the first quarter.  The average mine recovery rate was    1.0% higher compared to that of the comparative quarter ended June 30, 2006.

Operating earnings for the quarter were $3.7 million. This compares to $2.9 million for the comparative quarter ended June 30, 2006.

Revenue for the quarter was $13.7 million from the sale of 20,992 ounces of gold.

Mining at the Fazenda Nova Mine stopped in May 2007 as the Mine is at the end of its mine life.  During the quarter the Mine produced a total of 2,380 ounces of gold for total production for the six months of 6,427 ounces of gold.  The Company has recorded a loss on the impairment of the Fazenda Nova Mine for the six months of $1.8 million and a mine operating loss of $4.7 million for the six months ended June 30, 2007 of which $2.7 million was recognized during the second quarter.

6.           LIQUIDITY AND CAPITAL RESOURCES

Cash and cash equivalents as at June 30, 2007 were $89.0 million compared to $69.8 million as at March 31, 2007 and $69.7 million as at December 31, 2006.  Cash increased due to cash flows generated from operations.

Working capital increased to $120.6 million as at June 30, 2007 compared to $97.4 million as at March 31, 2007 and $53.0 million as at December 31, 2006. The increase in working capital was mainly due to the ramp up of concentrate sales from the Company’s Chapada Mine.

Gold sales are made at spot prices and receivables turn around in approximately 3 to 5 days. Copper concentrate sales are made in accordance with certain smelter off-take agreements whereby provisional payments of approximately 90% are received within 1 to 4 weeks after shipping. Final assays and payment related to these sales are received approximately 2 to 3 months thereafter.

OPERATING CASH FLOW

Cash flow generated from operations before changes in non-cash working capital items for the quarter was $90.9 million compared to $15.1 million for the comparative quarter ended June 30, 2006 an increase of approximately  504.0%.  Cash flow from operations before changes in non-cash working capital items for the six months ended June 30, 2007 was $159.8 million compared to $22.9 million for the comparative six month period ended June 30, 2006.

The strong cash flow growth results primarily from the ongoing production expansion.  Unrealized losses on derivatives of $20 million for the three months has been added back to accounting profit as the mark-to-market adjustments are non-cash charges.

Cash inflow from operations for the three and six months ended June 30, 2007 was $78.9 million and $92.7 million respectively.  Working capital continues to increase in line with the production growth.

FINANCING ACTIVITIES

Cash outflow from financing activities for the quarter ended June 30, 2007 were $5.0 million and included the following:

•      $3.0 million inflow from the exercise of options and warrants;

•      dividends paid of $3.8 million; and

        •      derivative hedge settlements of $3.5 million.

Cash inflow from financing activities for the comparative quarter ended June 30, 2006 were $87.8 million.

Cash inflow from financing activities for the six month period ended June 30, 2007 was $9.7 million compared to $93.1 for the comparative six month period ended June 30, 2006 which included larger cash inflows from the exercise options and warrants and an equity financing for gross proceeds of $179.7 million.

During the period, the Company increased its revolving credit facility to $300 million from the original $200 million entered into in December 2006.  The increased facility remains with similar terms as further described in Note 15 of the consolidated interim financial statements for the period ended June 30, 2007.  As at June 30, 2007, the Company had not drawn any amounts under the facility.

INVESTING ACTIVITIES

Cash flow from investing activities includes expenditures on property, plant and equipment, mineral properties and construction. A cash outflow from investing activities of $57.9 million for the quarter consisted primarily of expenditures of $25.4 million on mineral properties, and $22.8 million on property, plant and equipment acquisitions.

Current quarter cash outflows from investing activities compare to an outflow of $57.2 million during the comparative period June 30, 2006.

Cash outflows from investing activities for the six months ended June 30, 2007 were $86.7 million which compares to an outflow of $117.6 million for the comparative six months ended June 30, 2006.

7.           CAPITALIZATION

Shareholders’ equity as at June 30, 2007 was $1.8 billion compared to $1.8 billion as at March 31, 2007 and $1.7 billion as at December 31, 2006.

SHARE CAPITAL

As at June 30, 2007, the Company had 355.2 million (December 31, 2006 – 344.6 million) common shares outstanding. The weighted average shares outstanding for the quarter ended June 30, 2007 was 354.5 million common shares and 366.7 million common shares on a diluted basis.

The Company issued a total of 0.5 million and 5.7 million common shares during the three and six month periods ended June 30, 2007 in respect to the exercise of stock options and warrants.  As at June 30, 2007, the Company had a total of 48,500 shares to be issued.

WARRANTS

As at June 30, 2007, the Company had a total of 16.8 million (December 31, 2006 - 16.9 million) share purchase warrants outstanding with an average exercise price of C$8.66 per share. Expiry dates on share purchase warrants range from July 2007 to May 2011, and exercise prices range from C$2.09 to C$19.08. All outstanding warrants were exercisable as at June 30, 2007. The weighted average remaining life of warrants outstanding was 2.14 years (December 31, 2006 - 2.64 years).

There were no warrants issued during the quarter.

As at June 30, 2007 dilutive warrants would contribute an additional $52.6 million into treasury.

STOCK OPTIONS AND STOCK-BASED COMPENSATION

As at June 30, 2007, a total of 10.7 million stock options were outstanding of which 10.6 million were exercisable. This compares to a total of 16.1 million stock options outstanding as at December 31, 2006 of which 15.9 million were exercisable. Stock options outstanding as at June 30, 2007 had a weighted average exercise price of C$8.37 per share (December 31, 2006 - C$7.27 per share) and a weighted average remaining life of 3.94 years (December 31, 2006 - 4.55 years).

There were no stock option grants during the quarter.  The company expensed a total of $0.1 million related to deferred compensation on vested options during the quarter.

As at June 30, 2007, dilutive options would contribute an additional $89.2 million into treasury.

8.           GENERAL AND ADMINISTRATIVE EXPENSES

General and administrative expenses were $10.7 million for the quarter which compares to $8.3 million for the first quarter of 2007 and $5.3 million for the comparative quarter ended June 30, 2006. The increase in general and administrative expenses reflects the Company’s growth from operations and acquisitions and the growing infrastructure to support its production growth.

9.           FOREIGN EXCHANGE

The Company recognized a foreign exchange loss of $5.3 million during the quarter comprised of exchange losses in Brazil of $7.3 million and $1.2 million in Argentina, offset by an exchange gain of $3.2 million in Canada. This compares to a foreign exchange gain of $2.1 million for the comparative period ended June 30, 2006. On a year to date basis the Company has recognized a foreign exchange loss of $6.7 million compared to $5.6 million foreign exchange loss in the six months ended June 30, 2006.

The Real-US Dollar exchange rate as at June 30, 2007 was 1.9262 compared to 2.0504 as at March 31, 2007. This represents an increase in the value of the Real of approximately 6% during the quarter.

The exchange loss in Argentina was due to the strengthening of the Peso over the first quarter. The Argentine Peso - US Dollar exchange rate as at June 30, 2007 was 3.1012, a change of approximately 1.0% from the rate as at March 31, 2007 of 3.1235.

The Canadian–US Dollar exchange rate as at June 30, 2007 was 1.0634 compared to 1.1546 as at March 31, 2007.  This represents an 8% strengthening of the Canadian Dollar relative to the US dollar.

As at the quarter end, the Company held cash of US$32.1 million, C$5.1 million, R$81.6 million, ARG$28.1 million and LEM$10.9 million.

During the first quarter, the Company entered into currency hedges whereby the value of the Real has been fixed against the US Dollar as further discussed in Section 15 “Currency Hedging”.

10.           INVESTMENT INCOME AND INTEREST EXPENSE

The Company had interest and other business income of $4.1 million and $5.0 for the three and six months ended June 30, 2007, respectively. This compares to $1.6 million and $3.1 in interest income for the comparative periods ended June 30, 2006. Interest expense for the three and six months ended June 30, 2007 was $3.6 million and $6.0 million, respectively, consisting of mainly of interest expense related to copper derivatives.  This compares to $25.7 million for the comparative three and six month periods consisting mainly of financing fees related to the repayment of previously held debt.

11.           INCOME TAXES

The Company recorded an income tax expense of $13.9 million for the quarter ($34.7 million for the six months ended June 30, 2007). The tax provision reflects a future income tax recovery of $2.2 million ($10.7 million income tax expense for the six months ended June 30, 2007) and a current income tax expense of $16.1 million ($24.0 million for the six months ended June 30, 2007). The current quarter income tax expense represents 20.8% (30.2% for the six months ended June 30, 2007) of pre-tax income for the second quarter.

The consolidated balance sheet reflects an increase in current and future income tax liabilities as the Company records increased 2007 taxable income from the Chapada Mine.  Additionally, the tax provision for the quarter reflects accrued foreign exchange gains and losses in Brazil and in Canada on US$denominated inter corporate debt which represents approximately 4.0% of the effective tax rate for the quarter (6.8% for the six months ended June 20, 2007). This debt is eliminated on consolidation. The consolidated effective tax rate excluding the tax impact of the intra group foreign exchange gain was 16.8% for the second quarter (23.3% for the six months ended June 30, 2007).

The income tax expense reported and the Company’s effective tax rate will vary period to period depending on the foreign currency exchange rate then in effect. However, the income tax is payable only if the inter-corporate debt is repaid and as such, as that debt may never be repaid, the income tax expense may never be paid. The amount of the tax liability will depend on the foreign exchange rate in effect at the time that the inter-corporate debt is repaid.  The effective tax rate will also be dependent on the tax impact of the copper mark-to-market fluctuations.

The decrease in the second quarter tax provision was a result of the following items:  an increase in the mark-to-market loss on derivatives; a decrease in the mark-to-market gain on concentrate receivables; and a reversal of the valuation allowance to recognize the future tax asset on the Jacobina business interruption.

The Company has commenced the implementation of a global restructuring plan in order to minimize the annual global effective tax rate.  The restructuring plan will be completed in stages over the next two quarters.  The full impact of the restructuring plan will be realized in 2008.  Based on the current gold prices, the tax rate on operations is projected to be in the range of 22% to 25%.

A reconciliation of the Company’s statutory rate to the actual provision is provided in Note 14 to the consolidated financial statements.

12.           CLOSURE AND RECLAMATION COSTS

The Company accrues reclamation and closure costs at their fair value. Fair value is determined as the discounted future cash expenditures. Significant management judgments and estimates are made when estimating reclamation and closure costs. Reclamation and closure costs are estimated based on the Company’s interpretation of current regulatory requirements and are amortized over the life of each mine on a unit-of-production basis.

Accretion charged during the quarter was $0.4 million. This compares to $0.2 million for the quarter ended June 30, 2006.  Accretion expense for the six month period ended June 30, 2007 was $0.7 million.  This compares to $0.3 million for the comparative six months ended June 30, 2006.

13.           CONTRACTUAL COMMITMENTS

In addition to commitments otherwise reported in the MD&A the Company is contractually committed to the following as at June 30, 2007 (in thousands of dollars):

Year	2007		2008		2009		2010		2011 and thereafter		Total

14.           CURRENCY HEDGING

The Company has entered into forward contracts to hedge against the risk of an increase in the value of the Real versus the US Dollar with respect to a portion of the expected Real expenditures. These contracts fix the rate of exchange for the sale of approximately 280 million Reais at an average exchange rate of 2.316 Real to the US Dollar. These contracts are based on projected monthly sales beginning in February 2007 through to February 2010.  Of the amount hedged approximately 31.6 million Reais has been settled to date.

The currency hedge has been accounted for as a cash flow hedge with the effective portion of the hedge of $3.3 million and $8.4 million for the three and six months ended June 30, 2007 credited to other comprehensive income and the ineffective portion of $1.0 million and $2.7 million for the three and six months ended June 30, 2007 credited to earnings.

15.           COPPER HEDGING PROGRAM

In 2006, the Company implemented a copper hedging program beginning in late 2005 that was intended to help secure a less than two year payback at its Chapada Mine and to protect future earnings and cash flows.  Hedging copper also provides further leverage to gold prices and increases the impact of gold on the Company’s unhedged revenue.

This program includes a combination of forward and call option contracts intended to economically hedge against the risk of declining copper prices for a portion of its forecast copper concentrate sales. This copper economic hedging program provides a forward price of $1.37 per pound of copper for a total of 50.2 million pounds of copper in 2007 and a forward price of $2.75 per pound of copper for a total of 90 million pounds in 2008. The program includes long call options at an average strike price of approximately $1.67 per pound of copper on the 2007 hedge and an average strike price of approximately $3.25 per pound of copper on the 2008 hedge thereby permitting the Company to participate in price increases in the event that copper prices exceed the strike price of the options. The program requires no cash margin, collateral or other security from the Company.

Since Chapada produces a concentrate of copper and gold which is sold in concentrate form, under accounting rules, hedge accounting may not be possible. Accordingly, changes in the fair value of the financial instruments will be reflected in current earnings from period to period. This will result in fluctuations in net earnings from period to period until such time the contracts are closed in January 2009. The unrealized mark-to-market loss represents the value on notional cancellation of these contracts based on market values as at June 30, 2007 and does not represent an economic obligation for the Company nor does it represent an estimate of future gains or losses nor does it represent an economic obligation for the Company.

The Company recorded a mark-to-market loss of $19.9 million and $28.7 million for the three and six month periods ended June 30, 2007 (three months June 30, 2006 – $11.4 million, six months June 30, 2006 – $20.3 million) in respect to these commodity contracts.  The Company had a total of 120.4 million pounds under open contracts as at June 30, 2007.

Subsequent to the quarter end, the Company entered into copper forward contracts intended to hedge copper prices at a weighted average forward price of $2.97 per pound of copper for a total of 124.9 million pounds of copper for 2008, 2009 and 2010 ($3.33 for 2008, $3.00 for 2009 and $2.67 for 2010) and $2.37 per pound of copper for a total of 35 million pounds of copper for 2011.  One of these benefits of these hedges is that it increases the impact of gold to the Company’s unhedged revenue and as such increases the Company’s leverage to gold.

16.           CONTINGENCIES

(a) A sales tax audit was completed by Brazilian state tax authorities which could result in a liability, including penalties or a potential loss of recoverable Brazilian sales tax credits, which have been recorded as receivables, of approximately $1.6 million including penalties that have been recorded as receivables. The Company has not recorded the potential negative impact of the results of the sales tax audit as at March 31, 2007 as it is the Company’s view that the total amount of sales tax credits is recoverable. The Company is currently undergoing an appeal process and while it is not possible to determine the ultimate outcome of such process at this time, the Company believes that the ultimate resolution will not have a material effect on the Company’s financial condition or results of operation.

(b) The Company has a contingent liability to settle health related claims by former employees of Jacobina Mineração e Commercio Ltda (“JMC”). The Company estimates this contingency to be $18.5 million which has been accrued as at June 30, 2007. The Company will continue to monitor the issue in the future. Adjustments if any, will be recorded if circumstances change or the matter is settled. The liability has increased from first quarter by $1.3 million due to the impact of in the movement of the Real relative to the US dollar during the quarter.

17.           ACQUISITIONS AND GOODWILL

During the fourth quarter of 2006, the Company acquired Viceroy Exploration Ltd. With this acquisition, the Company acquired a development stage project, Gualcamayo in Argentina. The acquisition was accounted for using the purchase method of accounting for business combinations. The cost of the acquisitions has been allocated to identifiable assets and liabilities acquired. The allocation of the purchase price for Viceroy Exploration Ltd. represents management’s initial estimates. A detailed valuation is expected to be completed in 2007. Although the results of this review are presently unknown, it is anticipated that it may result in a change to the amounts assigned to mineral properties and a change to the value attributable to tangible assets. The unallocated purchase price has been included in mineral properties for balance sheet presentation.

Additionally, during the 2006 year, the Company acquired Desert Sun Mining Corp. Approximately $55 million, being the excess of the purchase price over the net identifiable assets acquired of Desert Sun Mining Corp., represented goodwill. Goodwill primarily represents the advantage of sustaining and growing a portfolio of mining operations and synergies that are realizable from consolidating certain business functions. The Company will test for impairment of goodwill on an annual basis during the fourth quarter of the fiscal year.

18.           OFF-BALANCE SHEET ARRANGEMENTS

The Company does not have any off-balance sheet investment or debt arrangements.

19.           EXPLORATION AND DEVELOPMENT

Yamana continues to actively explore its exploration targets around existing mines and additional regional exploration targets located on four major greenstone belts in South America. The Company spent $4.5 million during the second quarter on exploration programs. This compares to $8.5 million during the previous quarter ended March 31, 2007 for a total $13 million spent year to date.

São Francisco, Brazil

Yamana has begun its previously announced deep drilling program to investigate the potential resource extension in depth at São Francisco gold mine, Mato Grosso, Brazil. When construction began at São Francisco in 2006, Yamana indicated that a deep drilling program would begin some time after the start up of operations.

Drilling to date has continued to identify mineralization.  Drill hole SF-487 returned two mineralized intervals grading 7.17 g/t Au over 1.5m (true width) and 6.08 g/t Au over 8.9 metres (true width), including 30.1 g/t Au over 1 metre (true width).  Results from SF-486 returned 4.82 g/t Au over two metres, within a zone of 1.33 g/t Au over true width of 18 metres, at a depth of 778 metres (514 metres below the final pit bottom).  The two deep holes drilled to date extend the mineralization 300 metres deeper than the current resources. Drilling will continue to investigate the deep zone to the east of the deposit.

Measured and indicated resources at São Francisco as at December 31, 2006 total 88.1 million tonnes at 0.66 g/t gold, containing 1.87 million ounces of gold (total measured resources of 36.6 million tonnes at 0.73 g/t gold and total indicated resources of 51.5 million tonnes at 0.61 g/t gold).  Additional inferred resources total 110.6 million tonnes at 0.40 g/t Au, containing 1.436 million ounces of gold. This represents a significant increase from the original feasibility study predominantly along strike of the open pit mine. Extension drilling along strike continues as well as in-fill drilling to upgrade resources to reserves.

These results continue to demonstrate the potential at São Francisco for further open pit mine life and a possible underground deposit.

C1-Santa Luz, Brazil

C1-Santa Luz is located on the Rio Itapicuru Greenstone Belt north of the Fazenda Brasileiro mine. The most recent resource estimate update for the C1 and Antas 1 contiguous deposits, completed in February 2007, is summarised in the following table:

C1/Antas 1 Mineral Resource Estimates (0.5g/t Au cut-off)
	Indicated									Inferred
	Tonnes			Au			Ounces			Tonnes			Au			Ounces
Deposit		(000s	)		(g/t	)		(000s	)		(000s	)		(g/t	)		(000s	)
C1		17,859			1.62			927			8,167			1.4			374
Antas 1		1,749			2.02			114			419			2.1			28
Total		19,608			1.65			1,041			8,586			1.5			402

(1) The Mineral Resources for the C1/Antas 1 deposits as set out in the table above have been prepared by Chris Arnold, principal resource geologist of GRD Minproc Limited, under the direction of Ross Oliver, manager mining & geology, GRD Minproc Limited.

Year to date, a total of 8,745 metres in 59 diamond drill holes were completed primarily on Antas 3 North, which is an adjacent target to C1 with potential to increase the known resource up to 1,200 metres of strike length. Three holes were initially drilled in Antas 2; a smaller and higher grade drill target located 800 metres southwest of C1. Drill results received so far have confirmed the expansion of the open pitable resource as shown in the table below.

The most significant results from drilling at Antas 3 North and Antas 2 include:

Hole	Area	From	To	Interval	Gold Grade
		(m)	(m)	(m)	g/t Au
AT-6	Antas 3	105.9	113.0	7.1	2.38
		135.1	149.0	13.9	1.58
AT-7	Antas 3	169.9	173.0	3.1	2.65
AT-8	Antas 3	130.4	136.3	5.9	2.88
AT-9	Antas 3	148.1	166.1	17.0	1.77
AT-11	Antas 3	154.0	180.0	26.0	1.32
AT-41	Antas 3	85.6	103.0	17.4	2.52
AT-138	Antas 3	32.0	35.6	3.6	1.08
ANTR202	Antas 2	8.0	30.0	22.0	8.09
ANTR205	Antas 2	15.0	21.0	6.0	2.98
ANTR191	Antas 2	0.0	2.0	2.0	1.15
		7.0	16.0	9.0	1.84

Drill core samples from C1-Santa Luz  were analyzed for fire assay at SGS-Geosol, an ISO 9001, 2000 laboratory, in their Jacobina facility, and checked by ACME Laboratory, based in Goiania, Brazil.  Accuracy and precision of results is submitted to a systematic quality control protocol, following industry standards. 

All of these results are near surface and Yamana believes that the open pit resource is likely significantly larger at grades higher than originally anticipated.

An intensive drilling program of 20,000 metres in 174 holes is currently ongoing at C1-Santa Luz, targeting an open pitable resource expansion to the south. Nine drill rigs are currently on site and Yamana expects to complete the drilling program by early October.  Drill targets included in this program are:  C1-Antas 1 in-fill, Antas 3 North, Antas 2, Antas 3 South, Mansinha and Marí which are all located within 12 km of the planned mill facilities.

The feasibility study is expected by the end of 2007 with operations beginning in early 2009.

C1-Santa Luz is significant as it further demonstrates Yamana’s commitment to organic, internal growth. Originally targeted for drilling in late 2004, C1-Santa Luz was taken to a scoping study which indicated an initial reserve although continued drilling was recommended. The February 2007 resource estimate significantly increased the known resource in the scoping study. Current and planned drilling suggest a larger deposit and at higher grades than contemplated in February.

Gualcamayo, Argentina

The feasibility study for the main Quebrada Del Diablo (QDD) deposit is pending.  In addition, a resource update for the  Amelia Ines and Magdalena (AIM) satellite deposits at Gualcamayo, located approximately 1.0 and 1.5 km northwest of QDD, is in progress.

Drilling results since the 2004 resource estimate as previously disclosed include the following: Hole QD-400 (4.90 gpt Au over 149.15 m), Hole QD-403 (6.61 gpt Au over 45.22 m), Hole QD-399 (10.00 gpt Au over 21.50 m), Hole QD-389 ( 2.65 gpt Au over 78.67 m)  and Hole QD-397 ( 2.58 gpt Au over 63.96 m). The pending resource update will account for this information.

Some of the more recent significant drill core length intercepts include QD-411 (51 metres at 2.25 g/t Au), QD-412 (114 m at 4.73 g/t Au), QD-414 (72 m at 4.4 g/t Au), QD-415 (36m at 1.58 g/t Au), QD-416 (44m at 1.22 g/t Au), QD-427 (71m at 1.99 g/t Au, including 36m at 2.70 g/t Au), QD-435 (17.7m at 3.98 g/t Au), QD-436 (32.4m at 3.23 g/t Au) and QD-439 (28 m at 4.12 g/t Au). The additional higher grade oxides outcrop along the eastern edge of the Amelia Ines deposit are easily accessible with existing road infrastructure and could therefore have a significant impact on the Gulacamayo project’s economics in the initial years of production as the average grade is more than 2.5 times that of the main QDD deposit.  These results will be included in a new AIM resource estimate used to complete an AIM feasibility study by the end of September 2007.

Yamana’s commitment to resource expansion includes further defining and increasing resources at properties or mines that become part of Yamana through acquisition. The Gualcamayo project was acquired only in late 2006 and since then significant efforts have been made at advancing the feasibility study and expanding the size of the deposit.

San Andrés, Honduras

Yamana continues to significantly expand the resource base at San Andrés. Since acquiring the property, Yamana has increased the measured and indicated resources and the resource base is expected to increase further by the end of 2007 as drilling continues. Further efforts are also underway to upgrade resources to reserves as Yamana intends to develop a mine plan providing for production of 100,000 ounces per year (currently 65,000 ounces) for a ten year period (currently approximately five years).

Pillar de Goias, Brazil

Drilling is in progress on the Pillar de Goias Greenstone Belt in central Brazil to further delineate targets. To date, there are 28 drill holes including 19 historical and 9 recently drilled by Yamana with results pending on two initial targets.

Nicaragua Exploration

Geological mapping and sampling is underway at two main targets in Siuna District, Nicaragua. Cerro Potosi has a known resource and historical drilling results. At Cerro Aeropeurto, located 1.1 kilometres south of Cerro Potosi, a historical RC hole intersected 49 metres at a grade of 2.3 g/t Au including 9 metres at 11 g/t Au, 4.5 metres at 56 g/t Au and 3 metres at 10% Zn. Cerro Potosi and Cerro Aeropeurto are early-stage targets, and may be part of the same structure.

Yamana Exploration in 2007

Yamana will continue its existing and new exploration programs for the remainder of 2007 having allocated a total budget of approximately $32 million focusing primarily at and around Gualcamayo in Argentina, on the Bahia Gold Belt near and north of Jacobina mine, on the Itapicuru Greenstone Belt north of Fazenda Brasiliero mine, on the Pillar de Goias Greenstone Belt and on the Guapore Greenstone Belt south of the São Francisco mine.  Yamana will continue to provide regular exploration updates throughout the year.

The exploration programs are being supervised by Dr. Evandro Cintra, P. Geo., vice president, exploration of Yamana Gold who is a Qualified Person as defined by National Instrument 43-101.  Dr. Cintra has verified the data disclosed and has reviewed and approved the contents of this press release.

20.           GOLD AND COPPER MARKETS

For the quarter ended June 30, 2007, spot gold prices averaged $668 per ounce. This average price was 6% higher than the comparative second quarter of 2006 and 3.0% higher than the first quarter of 2007.  The Company’s gold is sold at spot prices in world markets. The Company’s revenue and profitability is highly dependant on spot gold prices. Gold prices are currently being supported by positive market fundamentals. Decreased mine supply, steady investment and physical demand, lower central bank selling and increased producer de-hedging are all driving prices. As well, gold’s appeal as an inflation and U.S. dollar hedge have continued to underpin higher gold prices in the recent near-term. Due to these continuing factors, the Company expects gold prices to remain well supported in the near to mid-term although the market has been displaying a high degree of volatility, which is expected to continue in the near term.

For the quarter ended June 30, 2007, spot copper prices averaged $3.46 per pound, approximately 29% higher than the average spot price for the first quarter. The rising copper price during the current commodity cycle has been driven by several factors including rising demand underpinned by strong Chinese consumption, lower industry-wide mine production growth, low exchange-traded and consumer inventory levels, supply disruptions and growing investment demand.  These factors caused copper prices to increase and remain at current levels or comparable to current levels. The Company expects that the aforementioned factors will continue to support copper prices for the foreseeable future although the market has been displaying a high degree of volatility, which is expected to continue in the near term.

21.           RISKS AND UNCERTAINTIES

Exploration, development and mining of metals involve numerous inherent risks. As such, the Company is subject to various financial, operational and political risks that could have a significant impact on its profitability and levels of operating cash flows. Although the Company assesses and minimizes these risks by applying high operating standards, including careful management and planning of its facilities, hiring qualified personnel and developing their skills through training and development programs these risks cannot be eliminated. Such risks include changes in local laws governing the mining industry, a decline in the price of gold or copper and the activity in the mining sector, uncertainties inherent in estimating mineral reserves and mineral resources and fluctuations in local currency against the US Dollar.

The Company holds mining properties in Brazil, Honduras and Argentina and as such is exposed to the laws governing the mining industry in those countries. The governments in those countries are currently supportive of the mining industry but changes in government regulations including taxation, the repatriation of profits, restrictions on production, export controls, environmental compliance, expropriation of property and shifts in the political stability of the country and labour unrest could adversely affect the Company and its exploration and production initiatives in these countries. In December 2006, the Company submitted an Environmental Impact Statement document to the San Juan authorities where the Gualcamayo Project is located. However, there is no assurance that an EIS permit will be issued.

To mitigate land title risks, the Company makes no commitments and does not undertake exploration without first determining that necessary property rights are in good standing. However, despite the Company’s best efforts, land title may still be affected by undetected defects.

Conducting exploration and production in Latin America also exposes the Company to the risk of currency fluctuations. A significant portion of the Company’s expenditures are denominated in Brazilian Reais, Honduran Lempira, Argentine Peso and Canadian Dollars and revenues are earned in US Dollars. A strengthened local currency could adversely affect the Company’s costs denominated in US dollars. Historically, the Real has been highly volatile relative to other currencies and can fluctuate significantly against the US Dollar over short-term periods.

The mining industry is intensely competitive and is highly dependent on commodity prices. A decline in the price of gold or copper could negatively impact the Company’s operations.

Mineral reserves and resources are estimates which may differ significantly from actual mining results.

Readers are encouraged to read and consider the risk factors more particularly described in the Company’s Annual Information Form for the year ended December 31, 2006. Such risk factors could materially affect the future operating results of the Company and could cause actual events to differ materially from those described in forward-looking statements relating to the Company.

22.           CRITICAL ACCOUNTING POLICIES AND ESTIMATES

In preparing financial statements in accordance with Canadian GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses for the period end. Critical accounting estimates represent estimates that are uncertain and for which changes in those estimates could materially impact on the Company’s financial statements. Management reviews its estimates and assumptions on an ongoing basis using the most current information available. The following accounting estimates are critical:

•      Closure and reclamation costs

Closure and reclamation costs are accrued at their fair value and are estimated based on the Company’s interpretation of current regulatory requirements.

•      Depletion and impairment of mineral properties

Depletion and impairment of mineral properties are impacted by estimates of reserves and resources. There are numerous uncertainties inherent in estimating mineral reserves and resources. Differences between management’s assumptions and market conditions could have a material effect in the future of the Company’s financial positions and results of operation.

The Company reviews and evaluates its mining interests for impairment at least annually or when events or changes in circumstances indicate that the related carrying amounts may not be recoverable. An impairment is considered to exist if the total estimated future undiscounted cash flows are less than the carrying amount of the assets. An impairment loss is measured and recorded based on discounted estimated future cash flows. Future cash flows are estimated based on expected future production, commodity prices, operating costs and capital costs.

•      Goodwill and impairment testing

The Company evaluates, on at least an annual basis, the carrying amount of goodwill to determine whether current events and circumstances indicate that such carrying amount continues to be recoverable. To accomplish this, the Company compares the fair value of the reporting unit to its carrying amounts. If the carrying value of the reporting unit exceeds its fair value, the Company compares the implied fair value of the reporting unit’s goodwill to its carrying amount, and any excess of the carrying value over the fair value is charged to operations. Assumptions underlying fair value estimates are subject to significant risks and uncertainties.

•      Reserve estimates

The figures for reserves and resources are determined in accordance with National Instrument 43-101, “Standards of Disclosure for Mineral Projects”, issued by the Canadian Securities Administrators. There are numerous uncertainties inherent in estimating mineral reserves and mineral resources, including many factors beyond the Company’s control. Such estimation is a subjective process, and the accuracy of any reserve or resource estimate is a function of the quantity and quality of available data and of the assumptions made and judgments used in engineering and geological interpretation. Differences between management’s assumptions including economic assumptions such as metal prices and market conditions could have a material effect in the future on the Company’s financial position and results of operation.

•      Income taxes

Future income tax assets and liabilities are determined based on the temporary differences between financial reporting and tax bases of assets and liabilities, as well as for the benefit of losses available to be carried forward to future years for tax purposes. Future income tax assets and liabilities are measured using substantially enacted tax rates and laws that will be in effect when the differences are expected to reverse. Future income tax assets are recorded on the financial statements if realization is considered more likely than not.

•      Purchase price allocations on business acquisitions

Purchase price allocations on business acquisitions are determined based on management’s best estimates. The allocation of the purchase price for Viceroy Exploration Ltd. represents management’s initial estimates. A detailed valuation is expected to be completed in 2007. Although the results of this review are presently unknown, it is anticipated that it may result in a change to the amounts assigned to mineral properties and a change to the value attributable to tangible assets.

23.           CONTROLS AND PROCEDURES

DISCLOSURE CONTROLS AND PROCEDURES

Disclosure controls and procedures are designed to provide reasonable assurance that all relevant information is gathered and reported to senior management, including the Company’s Chief Executive Officer and Chief Financial Officer, on a timely basis so that appropriate decisions can be made regarding public disclosure. The Company’s system of disclosure controls and procedures includes, but is not limited to, its Timely Disclosure and Confidentiality Policy, its Code of Business Conduct and Ethics, its Insider Trading Policy and Share Dealing Code, its Whistleblower Policy, its Fraud Policy, the effective functioning of our Audit Committee and procedures in place to systematically identify matters warranting consideration of disclosure by the Audit Committee.

As at June 30, 2007, there were no material changes in management’s assessment of disclosure controls and procedures. As such, the Chief Executive Officer and Chief Financial Officer have concluded, as of the end of the quarter ended June 30, 2007 the disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed in the Company’s interim filings (as such terms are defined under Multilateral Instrument 52-109 - Certification of Disclosure in Issuers’ Annual and Interim Filings) and other reports filed or submitted under applicable Canadian securities laws, is recorded, processed, summarized and reported within time periods specified by those laws and that material information is accumulated and communicated to management of the Company, including the Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

INTERNAL CONTROLS OVER FINANCIAL REPORTING

Management of the Company is responsible for establishing and maintaining effective internal control over financial reporting. The Company’s internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of the Company’s financial reporting for external purposes in accordance with accounting principles generally accepted in Canada and the United States of America to the Company’s management and board of directors regarding the preparation and fair presentation of published financial statements. Internal control over financial reporting includes:

• maintaining records that in reasonable detail accurately and fairly reflect transactions and dispositions of the assets of the Company;

• providing reasonable assurance that transactions are recorded as necessary for preparation of financial statements in accordance with generally accepted accounting principles;

• providing reasonable assurance that receipts and expenditures are made in accordance with authorizations of management and the directors of the Company; and

• providing reasonable assurance that unauthorized acquisition, use or disposition of Company assets that could have a material effect on the Company’s financial statements would be prevented or detected on a timely basis.

No significant changes in the Company’s internal controls or in other factors that could significantly affect these controls subsequent to the date of the evaluation, including any corrective actions with regard to significant deficiencies and material weaknesses, were made as a result of the evaluation as at December 31, 2006.

LIMITATIONS OF CONTROLS AND PROCEDURES

The Company’s management, including the Chief Executive Officer and the Chief Financial Officer, believe that any disclosure controls and procedures or internal controls over financial reporting, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, they cannot provide absolute assurance that all control issues and instances of fraud or error, if any, within the Company have been prevented or detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by unauthorized override of the control. The design of any systems of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Accordingly, because of the inherent limitations in a cost effective control system, misstatements due to error or fraud may occur and not be detected.

This report provides a discussion and analysis of the financial condition and results of operations (“Management’s Discussion and Analysis”) to enable a reader to assess material changes in financial condition between June 30, 2007 and December 31, 2006 and results of operations for the period ended June 30, 2007 and for the period ended June 30, 2006.

Cautionary Note Regarding Forward-Looking Statements

This Management’s Discussion and Analysis contains “forward-looking statements, within the meaning of the United States Private Securities Litigation Reform Act of 1995 and applicable Canadian Securities legislation” that involve a number of risks and uncertainties. Forward-looking statements include, but are not limited to, statements with respect to the future price of gold and copper, the estimation of mineral reserves and resources, the realization of mineral estimates, the timing and amount of estimated future production, costs of production, capital expenditures, costs and timing of the development of new deposits, success of exploration activities, permitting time lines, currency exchange rate fluctuations, requirements for additional capital, government regulation of mining operations, environmental risks, unanticipated reclamation expenses, title disputes or claims, limitations on insurance coverage and timing and possible outcome of pending litigation. Often, but not always, forward-looking statements can be identified by the use of words such as “plans”, “expects”, or “does not expect”, “is expected”, “budget”, “scheduled”, “estimates”, “forecasts”, “intends”, “anticipates”, or “does not anticipate”, or “believes”, or variations of such words and phrases or state that certain actions, events or results “may”, “could”, “would”, “might” or “will” be taken, occur or be achieved. Forward-looking statements are based on the opinions and estimates of management as of the date such statements are made, and they involve known and unknown risks, uncertainties and other factors which may cause the actual results, level of activity, performance or achievements of the Company to be materially different from any other future results, performance or achievements expressed or implied by the forward-looking statements. Such factors include, among others: risks relating to the integration of acquisitions; risk relating to international operations; the actual results of current exploration activities; actual results of current reclamation activities; conclusions of economic evaluations; changes in project parameters as plans continue to be refined; future prices of gold and copper; possible variations in ore reserves, grade or recovery rates; failure of plant, equipment or processes to operate as anticipated; accidents, labour disputes and other risks of the mining industry; delays in obtaining governmental approvals or financing or in the completion of development or construction activities; fluctuations in metal prices; as well as those risk factors discussed or referred to in the Company’s annual Management’s Discussion and Analysis and Annual Information Form for the year ended December 31, 2006 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 or opinions should change. Accordingly, readers are cautioned not to place undue reliance on forward-looking statements.

Notes to the Consolidated Financial Statements

For the Three and Six Month Periods Ended June 30, 2007 (with comparatives as at December 31, 2006 and for the Three and Six Month Periods Ended June 30, 2006)

(Tabular amounts in thousands or thousands of US Dollars unless otherwise noted; unaudited)

1.           BASIS OF PRESENTATION

The accompanying interim consolidated financial statements have been prepared in accordance with Canadian generally accepted accounting principles (“Canadian GAAP”) and include the assets, liabilities and operations of the Company and its wholly-owned subsidiaries. These interim consolidated financial statements do not contain all the information required by generally accepted accounting principles for annual financial statements and therefore should be read in conjunction with the annual financial statements of the Company for the year ended December 31, 2006. These interim consolidated financial statements follow the same accounting policies and methods of their application as the most recent annual financial statements except for changes disclosed in Note 2.

2.           CHANGES IN SIGNIFICANT ACCOUNTING POLICIES

Significant accounting changes

On January 1, 2007, the Company adopted three new accounting standards that were issued by the Canadian Institute of Chartered Accountants (CICA): Section 1530, Comprehensive Income; Section 3855, Financial Instruments - Recognition and Measurement; and Section 3865, Hedges. These standards were adopted on a prospective basis. Accordingly, the Company has not restated comparative amounts for prior periods.

(i)           Comprehensive Income

Section 1530 introduces comprehensive income, which consists of net income and other comprehensive income (“OCI”). OCI represents changes in Shareholders’ equity during a period arising from transactions other than changes related to transactions with owners. OCI includes unrealized gains and losses on financial assets classified as available-for-sale as well as changes in the fair value of the effective portion of derivative instruments included in cash flow hedges. The Company has included in its Interim Consolidated Financial Statements, a combined Statement of Shareholders’ Equity and Comprehensive Income for the changes in these items during the six months ended June 30, 2007. Cumulative changes in OCI are included in accumulated other comprehensive income (“AOCI”). Generally, gains and losses remain part of the balance of AOCI, until GAAP requires their recognition in net income.

(ii)           Financial Instruments - Recognition and Measurement and Hedges

Section 3855 establishes standards for recognizing and measuring financial assets, financial liabilities, and non-financial derivatives. Financial assets and financial liabilities, including derivatives, are recognized on the Consolidated Balance Sheet when the Company becomes a party to the contractual provisions of the financial instrument. Under this standard, all financial instruments are required to be measured at fair value on initial recognition except for certain related party transactions. Measurement in subsequent periods depends on whether the financial instrument has been classified as held-for-trading, available-for-sale, held-to-maturity, loans and receivables, or other financial liabilities. Transaction costs are expensed as incurred for financial instruments classified as held-for-trading. For financial instruments classified as other than held-for-trading, transaction costs are added to the carrying amount of the financial asset or liability on initial recognition and amortized using the effective interest method.

Financial assets and financial liabilities held-for-trading are measured at fair value with changes in those fair values recognized in interest and other business income. Loans and receivables, and other financial liabilities are measured at amortized cost and are amortized using the effective interest method. Available-for-sale financial assets are presented in available-for-sale securities in the Company’s Consolidated Balance Sheet and measured at fair value with unrealized gains and losses, including changes in foreign exchange rates, recognized in OCI. Investments in equity instruments classified as available-for-sale that do not have a quoted market price in an active market are measured at cost.

Derivative instruments are recorded on the Consolidated Balance Sheet at fair value, including those derivatives that are embedded in financial or non-financial contracts that are not closely related to the host contracts. Changes in the fair values of derivative instruments are recognized in net income with the exception of derivatives designated as effective cash flow hedges.

For cash flow hedges that qualify under Section 3865, the effective portion of any gain or loss on the hedging instrument was recognized in OCI and the cumulative ineffective portion was included in unrealized gain (loss) on commodity and currency contracts in the Statement of Operations.

Impact on adoption of Sections 1530 and 3855

The transition adjustments attributable to the remeasurement of financial assets and financial liabilities at fair value, other than financial assets classified as available-for-sale and hedging instruments designated as cash flow hedges, were recognized in the opening deficit as at January 1, 2007. The opening adjustment for the remeasurement of available-for-sale securities at fair value was recognized in opening AOCI as at that date.

The Company has recorded the following transition adjustments in the Consolidated Financial Statements:

(i) An adjustment to deficit to reflect the fair value adjustment of warrants held and the write-off of certain deferred costs previously capitalized on the balance sheet in the amount of $249.

(ii) An adjustment to AOCI to reflect the impact of change in fair value of available-for-sale securities in the amount of $2,663.

Future accounting changes

On December 1, 2006, the Canadian Institute of Chartered Accountants issued Section 3862, Financial Instruments - Disclosures; Section 3863, Financial Instruments - Presentation; and Section 1535, Capital Disclosures. All three Sections will be applicable for interim and annual financial statements relating to fiscal years beginning on or after October 1, 2007. Together, Sections 3862 and 3863 may be adopted in place of Section 3861, Financial Instruments - Disclosure and Presentation, before that date.

Section 3862 on financial instrument disclosures, places an increased emphasis on disclosures about risks associated with both recognized and unrecognized financial instruments and how these risks are managed and is consistent with Section 3861. The new Section removes duplicative disclosures and simplifies the disclosures relating to concentrations of risk, credit risk, liquidity risk and price risk currently found in Section 3861. Section 3863 on the presentation of financial instruments is unchanged from the presentation requirements included in Section 3861. Section 1535 on capital disclosures requires the disclosure of information about an entity’s objectives, policies and processes for managing capital.

3.           BUSINESS ACQUISITION

Acquisition of Viceroy Exploration Ltd.

In October 2006 the Company acquired approximately 95% of the outstanding common shares of Viceroy Exploration Ltd. (“Viceroy”), an exploration-stage company, through a take-over bid announced in August 2006. The Company offered Viceroy shareholders 0.97 of a Yamana common share for each Viceroy common share. Since the offer was accepted by holders of more than 90% of the Viceroy common shares, the Company commenced and completed the compulsory acquisition of the remaining Viceroy common shares not already owned at the same ratio of 0.97 of a Yamana common share for each Viceroy common share. Yamana exchanged all outstanding shares, options and share purchase warrants of Viceroy for similar securities of Yamana at an exchange ratio of 0.97 of a Yamana common share for 1 Viceroy common share. Total consideration paid was approximately $549.1 million comprised of approximately 52.5 million common shares, transaction costs and issued options and share purchase warrants acquired from Viceroy. Yamana has consolidated the results of operations from October 13, 2006. On January 2, 2007, an additional 4 million shares were issued in completing the compulsory acquisition.

A detailed valuation as at acquisition date is expected to be completed in 2007. Although the results of this review are presently unknown, it is anticipated that it may result in a change to the amounts assigned to mineral properties and a change to the value attributable to tangible and intangible assets. The unallocated purchase price has been included in mineral properties for balance sheet presentation and is subject to the results of this valuation.

14.           INCOME TAXES

The following table reconciles the statutory rates with the effective income tax rate in these financial statements:

	For the three months ended						For the six months ended
	June 30, 2007			June 30, 2006			June 30, 2007			June 30,  2006
Combined Canadian federal and provincial statutory tax rate		36.12	%		36.12	%		36.12	%		36.12	%
Less:
Lower tax rates in foreign jurisdictions		(2.9	)%		(2.9	)%		(2.9	)%		2.6	%
Permanent differences		(14.3	)%		(15.1	)%		(11.2	)%		(14.9	)%
Mark-to-market on financial instruments		(0.7	)%		0.0	%		0.8	%		0.0	%
Accrued foreign exchange gains and losses in Braziland Canada on inter-corporate debt (i)		4.0	%		6.3	%		6.8	%		(2.3	)%
Unrecognized (recognized) tax benefits		(1.4	)%		(12.4	)%		0.5	%		(14.1	)%
Actual effective tax rate		20.8	%		12.0	%		30.2	%		7.4	%
Income tax expense is represented by
Current income tax expense	$	(16,094	)	$	(2,082	)	$	(24,014	)	$	(2,760	)
Future Income tax recovery (expense)		2,186			9,634			(10,676	)		7,657
Net income tax (expense) recovery	$	(13,908	)	$	7,552		$	(34,690	)	$	4,897

(i) Tax provision for the quarter reflects accrued foreign exchange gains and losses in Brazil and in Canada on US$ denominated inter corporate debt. This debt is eliminated on consolidation. The consolidated effective tax rate excluding the tax impact of the intra group foreign exchange gain was 16.8% for the second quarter (32.4% for the first quarter).

The income tax expense reported and the Company’s effective tax rate will vary period to period depending on the foreign currency exchange rate then in effect. However, the income tax is payable only if the inter-corporate debt is repaid and as such, as that debt may never be repaid, the income tax expense may never be paid. The amount of the tax liability will depend on the foreign exchange rate in effect at the time that the inter-corporate debt is repaid.

15.           REVOLVING LINE OF CREDIT

During the period ended June 30, 2007 the Company increased its revolving credit facility to $300 million.  The credit facility, which is secured by a share pledge of certain of Yamana’s operating subsidiaries, matures in 2011.  Amounts drawn under the facility bear an interest rate of LIBOR plus 1.10% to 1.84% per annum depending on the Company’s debt to Earnings before Interest, Taxes, Depreciation and Amortization (“EBITDA”) ratio. Undrawn amounts are subject to a commitment fee of 0.375% to 0.631% per annum dependant on the Company’s debt to EBITDA ratio. As at June 30, 2007, the Company had not drawn any amounts under the facility.

19.           FINANCIAL INSTRUMENTS

(a)           Fair value of financial instruments

The carrying value of cash and cash equivalents, receivables, advances and deposits, accounts payable and income taxes payable (recoverable) approximate their fair values due to the relatively short-term maturities of these instruments. There were no material differences between the book value and fair value of long-term liabilities.

Derivative instruments are recorded at fair value. Fair value of derivative instruments are based on quoted market prices for similar instruments and on market closing prices at period end. The Company recorded a mark-to-market loss of $20.8 million and $29.6 million for the three and six month periods ended June 30, 2007, respectively (June 30, 2006 - $11.4 million and $20.3 million the for three and six month periods ended) on non-hedging derivative instruments during the period.

(b)           Currency risk

The Company’s sales are predominately denominated in US dollars. The Company is primarily exposed to currency fluctuations relative to the US dollar as a significant portion of the Company’s operating costs and capital expenditures are denominated in foreign currencies. Monetary assets denominated in foreign currencies are also exposed to foreign currency fluctuations. These potential currency fluctuations could have a significant impact on production costs and thereby the profitability of the Company. During the first quarter, the Company entered into forward contracts to economically hedge against the risk of an increase in the value of the Real versus the US dollar. Currency contracts totaling 280 million Reais have been designated against forecast Reais denominated expenditures as a hedge against the variability of the US dollar amount of those expenditures caused by changes in the currency exchange rates over the next four years of this 31.6 million Reais have been settled as at June 30, 2007. These contracts fix the rate of exchange for the sale of approximately 280 million Reais at an average exchange rate of 2.316 Real to the US Dollar. These contracts are based on projected monthly costs beginning in February 2007 through to February 2010. The effective portion of changes in the fair value of the currency contracts has been recorded in OCI until the forecast expenditure impacts earnings. The ineffective portion of changes in the fair value of the currency contracts has been recorded in current earnings.

(c)           Commodity price risk

The profitability of the Company is directly related to the market price of gold.  The Company has not hedged any of its gold. With the completion of the construction of the Company’s Chapada copper - gold mine which commenced commercial production on February 11, 2007, the Company is also exposed to the price of copper. During prior years, the Company entered into a combination of forward and call option contracts to economically hedge against the risk of declining copper prices for a portion of its forecast copper concentrate sales. The copper economic hedging program now in place provides a forward price of $1.37 per pound of copper for a total of 50.2 million pounds of copper in 2007 and a forward price of $2.75 per pound of copper for a total of 90 million pounds in 2008. The program includes long call options at an average strike price of approximately $1.67 per pound of copper on the 2007 hedge and an average strike price of approximately $3.25 per pound of copper on the 2008 hedge thereby permitting the Company to participate in price increases in the event that copper prices exceed the strike price of the options. The program requires no cash margin, collateral or other security from the Company.

20.           SUBSEQUENT EVENTS

(i) Business Acquisition

Subsequent to the period end, the Company signed a definitive business combination agreement with Northern Orion Resources Inc. (“Northern Orion”) whereby the Company will acquire all of the issued and outstanding securities of Northern Orion on the basis of 0.543 of a Yamana share for each Northern Orion share.  Concurrently, the Company filed a formal offer for all of the outstanding common shares of Meridian Gold Inc. (“Meridian”).  The offer to Meridian shareholders entitles shareholders to receive 2.235 Yamana common shares plus C$3.15 in cash for each Meridian common share tendered and taken up by the Company. The offer will remain open until August 27, 2007, unless the offer is withdrawn or extended by the Company.

The premium to Northern Orion shareholders was approximately 28.4% based on the respective average closing prices for Yamana shares and Northern Orion shares for the 20 trading days on the TSX immediately preceding the June 27, 2007 announcement date.

The premium to Meridian shareholders was approximately 24.6% based on the respective average closing prices for Yamana and Meridian shares for the 20 trading days on the TSX immediately preceding the June 27, 2007 announcement date.

The Northern Orion transaction is subject to customary conditions including receipt of all requisite third party and regulatory approvals and consents, court approval and approval by shareholders of Northern Orion.  It is also conditional on at least 66⅔% of the fully diluted outstanding Meridian common shares having been tendered to the Yamana offer.  The Northern Orion shareholder meeting to consider the business combination is currently scheduled for August 22, 2007, approximately five days prior to the expiry of Yamana’s offer to Meridian shareholders.

As part of the Northern Orion transaction, Northern Orion has agreed to enter into a definitive loan agreement with the Company for an amount of $200 million bearing interest at LIBOR plus 2%, repayable on the earlier of 12 months from the initial drawdown and 30 days following the acquisition by the Company of 100% of the fully diluted issued and outstanding shares of Meridian.  The first drawdown under the loan is conditional upon at least 66⅔% of the fully diluted issued and outstanding shares of Meridian having been tendered, and not withdrawn, to the offer.  The loan is not conditional upon the completion of the Northern Orion Transaction, and will not terminate in the event the termination of the Northern Orion Agreement, except in the case of a material breach of covenants by the Company and provided that another acquisition proposal for Northern Orion has not been made.

To complete the Meridian offer and the Northern Orion transaction, Yamana plans to issue approximately 309.8 million new common shares (226.1 million and 83.7 million common shares to Meridian and Northern Orion shareholders, respectively) and pay cash consideration of approximately $305 million to Meridian shareholders.  The cash consideration would be funded from the Northern Orion $200 million loan, internally generated cash and/or the existing $300 million revolving line of credit facility.  On an issued basis, the pro rata shareholdings of the combined company are anticipated to be:  53.4% existing Yamana shareholders, 34% existing Meridian shareholders and 12.6% existing Northern Orion shareholders.

(ii) Copper Derivatives

Subsequent to the quarter end, the Company entered into copper forward contracts intended to hedge copper prices at a weighted average forward price of $2.97 per pound of copper for a total of 124.9 million pounds of copper for 2008, 2009 and 2010 ($3.33 for 2008, $3.00 for 2009 and $2.67 for 2010) and $2.37 per pound of copper for a total of 35 million pounds of copper for 2011.

21.           COMPARATIVE FIGURES

Certain of prior period’s figures have been reclassified to conform with the current period’s presentation. The Company has separately disclosed advances and deposits and accounts receivable on the consolidated balance sheet. The Company has reclassified investments of $28.3 million as available-for-sale securities of $28.0 million and share purchase warrants held of $313,000.

Net earnings (loss), basic (loss) earnings per share and diluted earnings per share for the comparative period have been adjusted by $3 million to reflect additional stock-based compensation relating to options granted during that quarter that management identified had not been previously recorded in the second quarter.
