Spokane, Wa – Timberline Resources Corporation announced today that it has acquired three new silver-copper properties in western Montana and will subsequently lease them, along with its Minton Pass Project, to Sterling Mining Company, pursuant to a Letter of Intent signed by both companies.

The Minton Pass Project, along with the newly-acquired Lucky Luke, East Bull, and Standard Creek properties, are all located within the Montana Copper-Sulfide Belt in Lincoln and Sanders counties. All four prospects have the potential for Revett Formation hosted high-tonnage, low-grade silver and copper mineralization, similar to that found in well-known deposits at Troy, Rock Creek and Montanore. The properties were originally identified and held by U.S. Borax and its successor company, Kennecott Exploration, in the 1980s and early-1990s.

The Letter of Intent calls for Timberline to receive immediate debt forgiveness and repayment of certain expenses from Sterling. Timberline will then retain a 1-percent net smelter royalty (NSR) on any future production from the claims and will also receive annual cash payments of $5,000 per claim group beginning in 2007.

Timberline Resources Corporation is a Spokane-based junior mineral exploration company focused on the cost-effective acquisition, exploration, and development of promising mineral properties in the western United States. Timberline stock trades on the OTC Market under the symbol “TBLC”.
