 News Release 
 August 31, 2005

YAMANA GOLD INC. (TSX: YRI; AMEX: AUY; LSE (AIM): YAU) is pleased to announce that an overwhelming majority of its publicly traded warrants have been exercised in connection with the proposal made to warrantholders to exercise their warrants early. An aggregate of 39,866,635 warrants have been exercised representing approximately 98.3 percent of the total publicly traded warrants outstanding. These exercises have provided total gross proceeds of approximately Cdn$59.8 million that would otherwise not have been available to the Company until July 2008. In connection with these exercises, Yamana has issued 41,285,887 common shares being 1.0356 common shares issued for each warrant exercised.

The remaining 701,021 warrants that were not exercised will now be automatically exchanged for an aggregate of 476,203 common shares on the basis of 0.6793 of a common share for each warrant, which in effect provides a premium to the in-the-money value of the warrant. This exchange will be made pursuant to the terms of the warrant indenture which governs the warrants and no further action of those warrantholders will be required including payment of the warrant exercise price. The exchange is being completed based on the formula as described below. It is anticipated that registered holders of these unexercised warrants should receive certificates for their common shares within 5-10 business days.

The number of common shares to be received per warrant upon compulsory exchange = 98% multiplied by 1.0356 (being the total number of common shares issued per warrant upon exercise before August 29) minus C$1.50 (being the warrant exercise price) divided by $4.47, (being the lessor of i) the volume weighted average trading price of Yamana’s common shares for the five trading days ending on August 29, and ii) the closing price of Yamana’s common shares on August 29).

Yamana will have common shares outstanding of approximately 165.3 million on a basic basis and 178.4 million on a fully diluted basis. Available cash balances total approximately US$ 116 million. Following the exercise of its warrants, Santa Elina Mines Corporation, the principal shareholder of Yamana, now holds an aggregate of 33,546,134 common shares of Yamana, representing approximately18.8% on a fully diluted basis.

Peter Marrone, President and Chief Executive Officer commented on the warrant transaction stating, “This warrant transaction has been a resounding success as evidenced by more than 98% of warrants being exercised. It simplifies Yamana’s capital structure and strengthens the financial position of the Company. Further, the consolidation of the warrants into common shares increases Yamana’s market capitalization and public float which in turn should help to attract new investors and improve trading liquidity”.

A copy of the final short form prospectus dated July 18, 2005 relating the warrant transaction can be found at www.sedar.com.

BMO Nesbitt Burns acted as financial advisor to Yamana with respect to the warrant transaction.

This press release shall not constitute an offer to sell or the solicitation of an offer to buy nor shall there be any sale of these securities in any state in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state.
