NEWS RELEASE

YAMANA SEEKS TERMINATION OF MERIDIAN POISON PILL – OSC HEARING DATE SET

Toronto, Ontario, September 4, 2007 - YAMANA GOLD INC. (TSX:YRI; NYSE:AUY; LSE:YAU) announces that the Ontario Securities Commission (“OSC”) today confirmed a hearing date to consider the cease trading of Meridian Gold Inc’s shareholders rights plan or “poison pill” pursuant to an application made by Yamana.  The hearing will take place tomorrow morning, Wednesday, September 5, 2007 a 10:00 am ET.  In order to be accommodative, Yamana is seeking an order to have the rights plan cease trade on September 11th, on the condition that its bid be extended to that date.

Yamana will issue a press release providing any updates with respect to the poison pill and the bid deadline as appropriate following completion of the OSC hearing on Wednesday.  The Company fully expects that the shareholders rights plan will be cease traded and urges Meridian shareholders to tender their shares now.

Yamana has considered, amongst other matters, that Meridian has had more than two months to consider Yamana’s offer and to table any other alternatives.   It is time for the poison pill to be removed so that shareholders can respond to Yamana’s offer.

Yamana has offered C$4.00 plus 2.235 of a Yamana share per each Meridian share as part of a three-way combination between Yamana, Meridian and Northern Orion.  Northern Orion shareholders voted overwhelmingly in favour of the transaction on August 22, 2007.  The offer deadline currently is September 7, 2007.
