Gualcamayo Environmental Impact Statement Submitted

TORONTO, ONTARIO--(CCNMatthews - Dec. 19, 2006) - Yamana Gold Inc. ("Yamana") (TSX:YRI)(AMEX:AUY)(AIM:YAU) and Viceroy Exploration Ltd. ("Viceroy")(TSX:VYE)(AMEX:XVE) is pleased to announce that Minas Argentinas S.A. ("MASA"), its wholly owned subsidiary through its recent acquisition of Viceroy, today submitted the required Environmental Impact Statement ("EIS") for the Gualcamayo project to the government of the province of San Juan, Argentina. This EIS is the final submission required to receive the operating permit for mine development.

In terms of the recent decree passed by the provincial Government of San Juan, the process to receive the development permit will take approximately four months. Based on this, Yamana expects to proceed to the construction stage in mid-2007, with construction taking approximately 12 months.

"We are extremely pleased to reach this next milestone in the development of the Gualcamayo project," said Peter Marrone, President and CEO of Yamana. "Our team in Argentina has worked closely with both the local communities and government officials in completing all the necessary work required for our EIS documentation. There is very strong support for the project at the local community level and we expect to receive our required permits within the timeframe set out by the government. By submitting the EIS, we have advanced the project and accelerated the time frame for approval and start up of production, thereby providing comfort on the scheduled start up of operations in mid-2008."

About Viceroy Exploration Ltd.

On August 16, 2006, Yamana and Viceroy entered into an agreement pursuant to which Yamana agreed to make a take-over bid to acquire all of the outstanding common shares of Viceroy in exchange for Yamana common shares at the price of 0.97 Yamana common shares for each Viceroy common share. Yamana's take-over bid has been completed. Since the offer was accepted by holders of more then 90% of the Viceroy common shares, Yamana has commenced the compulsory acquisition of the remaining Viceroy common shares not already owned by Yamana at the same price of 0.97 Yamana common shares for each Viceroy common share. Viceroy continues as a public company pending completion of the customary compulsory acquisition process which follows the successful take-over bid of Viceroy by Yamana.
