Doublestar Resources Sells Scotia Claims to Geo Minerals

May 17, 2007

Vancouver, British Columbia - Doublestar Resources Ltd. (DSR-TSXV) has executed an agreement with Geo Minerals Ltd. ("Geo") whereby the latter has acquired Doublestar's interest in the Scotia group of claims, located 42 kilometres south of Prince Rupert in the Skeena Mining Division of British Columbia.

Under the terms of the agreement Geo will pay Doublestar $300,000 by way of $50,000 on closing (paid), $100,000 on June 15, 2007, and $150,000 on August 15, 2007.  In addition, Geo will issue to Doublestar 250,000 of its common shares.  Doublestar will retain a 2% net smelter return on the 4,987 hectare Scotia claims.

On March 1, 2007,  Doublestar announced the intent to merge with Selkirk Metals Corp. (TSX-V: SLK). Under the terms of the merger, it is proposed that each existing Class "A" share of Doublestar will be exchanged for one-half of one common share of Selkirk. 

The combined assets of both companies would result in approximately $14 million in current assets and a strong suite of B.C. base metal mineral projects.
