Development Of The Big Chief Mine 

PRESCOTT, AZ - Western Sierra Mining Corp., will begin the initial phase of development at the Big Chief mine located in Central Arizona.

The Big Chief is composed of several unpatented claims situated in the Hassayampa Mining District approximately 12 miles south of Prescott, Arizona. Most historical production from the Big Chief occurred during the late 1890s with some sporadic production thereafter. The property is mainly an underground gold deposit with some surface exposures and carries small amounts of silver. Western will begin a geological evaluation of the mine with the intent of expanding the current claim block. We will first take samples from the existing outcrops and trenches to confirm the previous exploration work. After applying for a small exploration permit, we intend to open the existing tunnels and sample the existing shafts in an effort to further define the present existing ore body. During this brief exploration period the company intends to construct a Plan of Operation to be submitted to the U.S. Forestry Service for review as we expand the program to include our initial pre-production intent. The company's address is 2750 Cisco Drive South, Lake Havasu City, AZ 86403, (928) 680-5513, fax: (928) 680-7066.
