Western Sierra Expands Exploration Capabilities

Western Sierra Mining Corp., (Pink Sheets:WSRA) announced today that it will significantly expand its exploration and testing capabilities with new portable processing equipment.

Western is nearing completion of a trailer mounted, self contained, portable mineral processing plant. The unit will have a primary water gravity concentration plant and will return the processed ore concentrates to a vibrating table also located on the base platform. The unit will be self sufficient for power, pumps and additional water recirculation to support both the primary and secondary concentrators.

With use of an associated portable crushing circuit, the platform can be used for both placer and hardrock. The platform is designed to be utilized where the presence of water, the availability of access or environmental issues present major obstacles. Expansion of the platform would allow it to be used for minor production prospects.

The unit is expected to be complete in the next couple of weeks and will be immediately deployed to a local property for initial testing of the equipment. From there it will deployed to two projects now under way in Arizona before being sent to Nevada for additional exploration work.
