Select Resources Starts Exploration on Shorty Creek Prospect, Alaska

Select Resources Corporation, a wholly owned subsidiary of Tri-Valley Corporation today announced it has initiated the first phase of its 2005 exploration program on the Shorty Creek property in Alaska. The Shorty Creek property consists of approximately 9,700 acres of Alaska state mining claims located about 75 road miles north of Fairbanks adjacent to the paved Elliot Highway.

A field crew has mobilized to the property primarily to conduct an extensive soil sampling survey over two intrusive-related gold-copper targets identified through integration of previous surface work on the property with satellite imagery, airborne geophysics, regional geochemistry, and geologic interpretation. A total of approximately 650 soil samples are expected to be collected over the two primary targets. In addition, reconnaissance sampling and geological mapping are planned as part of a preliminary evaluation of other prospective areas on the property identified through interpretation of public data sets.

The Shorty Creek property is located in the Tintina Gold Province in the Tolovana-Livengood Mining District, which has produced in excess of 500,000 ounces of placer gold. Previous exploration in the Shorty Creek area has identified mineralization and alteration characteristics consistent with other mineralization centers in the Tintina Gold Province, such as the multi-million ounce Fort Knox, Pogo, and Donlin Creek deposits.

Harry Noyes, Select's President, commented, "Our team of consultants has reviewed and reinterpreted all available data and identified several targets that merit priority attention. We are excited about the opportunity to evaluate this property in the context of the larger Tintina Gold Province, which was not recognized when the last systematic program of record was conducted on prospects in the claim block in 1990."
