EXCELSIOR MINING PROVIDES PERMITTING UPDATE - EPA CONFIRMS END OF PUBLIC COMMENT PERIOD FOR GUNNISON COPPER PROJECT

The United States Environmental Protection Agency has informed Excelsior Mining Corp. that the public comment period for the underground injection control permit for the Gunnison copper project has officially ended. Over the next several weeks, the EPA will review and respond to all comments received. Subsequent to the conclusion of this process, the UIC permit would then be issued. The UIC permit is the final permit required prior to starting construction and commencing production.

Stephen Twyerould, the president and chief executive officer, said: "The progression of our permitting efforts has gone much as we expected, and continues to move towards the issuance of our final operating permit, the federal UIC permit. The Gunnison copper project remains on track to become one of the most environmentally friendly and cost-effective copper producers in the world."
