June 25, 2009 Seabridge Gold Agrees to Sell Red Mountain Project for C$12 Million TORONTO, CANADA--(Marketwire - June 25, 2009) - Seabridge Gold (TSX:SEA)(NYSE Amex:SA) announced today that it has signed a letter of intent to sell 100% of its interest in the Red Mountain property located in British Columbia, Canada to BonTerra Resources Inc. (TSX VENTURE:BTR) for $7.0 million in cash plus a $5.0 million convertible debenture. The transaction is expected to close at the end of September, 2009. Seabridge President and CEO Rudi Fronk said "BonTerra is in a strong position to take our Red Mountain project forward. They have generated excellent exploration results on contiguous ground which could increase the size of the high-grade Red Mountain project and enhance its economics. We elected to take part of the proceeds of this proposed sale in the form of a convertible debenture so that we can continue to participate in Red Mountain's potential success. Cash proceeds from this transaction will enable Seabridge to continue advancing KSM and Courageous Lake towards feasibility without share dilution." For additional information on this transaction see www.bonterraresources.com Seabridge holds a 100% interest in several North American gold resource projects. The Company's principal assets are the KSM property located near Stewart, British Columbia, Canada and the Courageous Lake gold project located in Canada's Northwest Territories.
