Tri-Valley Unit Commences Mining Operations

BAKERSFIELD, CA -- (MARKET WIRE) -- August 29, 2005 -- Tri-Western Resources, LLC, a 50-50 joint venture operated by Select Resources Corporation, the minerals subsidiary of publicly traded Tri-Valley Corporation (AMEX: TIV), has commenced operations to begin quarrying and processing its Boron, California, specialty basalt deposit with the initial drill and blast scheduled for next week.

The specialty basalt is an augite olivine basalt with palagonite, which allows the material to break into near cubic form, compared to more common basalt, which breaks into shards.

This material has specialty use in the building and construction industries.

Initial production of the specialty basalt will consist of quarrying, crushing and screening material, and stockpiling of inventories. Sales of the specialty basalt will commence later during the fourth quarter 2005.

"We are very pleased with the progress of our Boron basalt project development and with the effort our employees have put forward to make this a success," said Dr. Henry J. Sandri, Executive Director, Tri-Western Resources, and Executive Vice President of Select Resources Corporation.
