Western Sierra Initiates New Exploration and Releases 2009 Gold Production Update

PRESCOTT, Ariz.--(BUSINESS WIRE)--Western Sierra Mining Corp. (OTC: WSRA) announced today that it will begin an exploration program for both gold and copper on the patented property of the Blue Bell Mine in central Arizona. Additionally, the company today released its complete 2009 Gold Production Update and Cash Flow analysis detailing Western Sierra’s Phase I development plans to commence and enhance gold mining simultaneously on the Gold Basin, Gold River and BlueBell/De Soto properties as one overall mining project.

The Gold Basin and Gold River Mines have in excess of $1 billion in total reserves, and at commercial production levels our Phase I Projected Cash Flow is forecast at approximately $9.1 million per year or roughly $.035 per share for the Gold River and Gold Basin Mines alone, subject to obtaining necessary financing and the successful completion of our business plan.

Michael Chaffee, CEO and President of Western Sierra Mining, commented, “Data obtained from both the Arizona Department of Mines and from the records of the early operators and mining companies concerning the Blue Bell Mine indicate the presence of significant amounts of copper and surface gold that may well be viable at today’s prices. Historical analysis and geological work at the De Soto Mine, similar in size and structure to the Blue Bell, continues, and the company anticipates providing information to the shareholders and the Board of Directors as it becomes available.”

Western has invested over $800,000 of its own funds to prepare these mines for operations, and over the past six months we have raised funds internally to make the transition from an acquisition and exploration company to a revenue based gold and silver production company.
