BAKERSFIELD, CA, Sep 28, 2005 (MARKET WIRE via COMTEX) -- On Tuesday, September 27, 2005 Tri-Western Resources, LLC, a 50-50 joint venture operated by Select Resources Corporation, the minerals subsidiary of publicly traded Tri-Valley Corporation (TIV), announced that the company has now initiated its mining operation with the ripping of 20,000 tons of basalt in preparation for crushing and screening at its Boron, California Basalt Quarry and begun product sales.

The quarry processing site has been prepared, the jaw and cone crushers are being placed and the stackers / conveyers are being upgraded and arranged. The three Mid-Western screens, cones and storage bins, and other material handling equipment used in sorting crushed rock will be arriving within the next two weeks so that the facilities can begin operations within a month with revenue beginning in the fourth quarter of the year. The Boron Quarry has an initial capacity of 500,000 tons per year on a single shift basis.

In the interim, Tri-Western Resources has been able to sell some of its overburden basalt to the City of Los Angeles Department of Water and Power (LADWAP) for ballast and rip-rap in association with LADWAP's new Pine Tree Wind Development Project located near Pine Tree and Jawbone Canyons, north of Tehachapi, California. LADWAP is in the process of erecting 80, 1.5MW wind turbines in Pine Tree Canyon, and it needs basalt for road repair and maintenance. As LADWAP proceeds with its development, it will repair and upgrade the Jawbone Canyon road, including building multiple permanent stream crossings and culverts.

"The LADWAP project presents us (Tri-Western Resources) with a number of opportunities," said Executive Director Dr. Henry (Rick) J. Sandri. "First, we are able to sell some of our overburden basalt at market rates, second, the rock is being applied to the Jawbone Canyon portion of the road, the same road we will be using for the mining and hauling of our Monarch calcium carbonate, and third, LADWAP will be upgrading the road so that it can transport the wind towers and blades. Our haul trucks will benefit from the improved roads."

"The industrial minerals business of our Select Resources mining subsidiary is, like our other enterprises, focused on producing increasing revenue from commodities with strengthening prices. Commercial production allows Tri-Valley to book proven reserves and contribute to bolstering the value per share of the Company, which is a primary corporate goal, and we will be reporting our multiple efforts in that regard at our upcoming shareholder meeting," said F. Lynn Blystone, president and chief executive officer of the parent, Tri-Valley Corporation.
