Western Sierra Inc. is a development stage Oklahoma mining company with options
to acquire specific mining concessions in Mexico and is currently under contract
with Minera La Escuadra, S.A. de C.V. as a joint venture partner to process
certain existing "mine dumps" at the Picacho mine near the city of Bacoachi,
Sonora, Mexico. The primary non-ferrous metal to be recovered is gold with
anticipated small amounts of silver.

The Company expects production at the Picacho plant to begin during the first
quarter of 2004. While the Company believes in the contract operation will be

will produce any gold or silver or any other commercial grade product that can
be sold by the Company at a profit.

being evaluated by the Company nor does the Company have sufficient capital to
develop these properties.
