WSRC Western Sierra Resource Corporation (CE)

Western Sierra Mining Corp., (Pink Sheets:WSRA) said today that it had reached a tentative agreement with the owners to develop the Silver Cord mine located in central Arizona.

The Silver Cord is a historically producing underground silver mine with some 800 feet of developed tunnels driven on a relatively flat silver vein. The vein structure carries minor amounts of gold and copper.

Western will first map and sample the mine while making initial recommendations for operational safety. Western will then oversee any mine modifications that may be necessary to work underground and initiate the appropriate permit applications.

In addition to the hard rock claims, there is an adjacent placer claim that will also be looked at in terms of commercial development.

The overall mine development program will be divided into separate phases, each new phase subject to a mutually agreed budget with the work being billed on "a cost plus" basis. It is anticipated the first phase will be initiated during the second quarter of 2011.
