May 12, 2008 – Coeur d’Alene – Timberline Resources Corporation (“Timberline”) announced today that its common shares have been listed on the American Stock Exchange (AMEX) effective at the market opening today under the trading symbol “TLR”. The AMEX specialist for Timberline will be J. Streicher & Co., LLC. Timberline common shares will cease trading on the OTC Bulletin Board, effective immediately.

Timberline Resources Corporation has taken the complementary businesses of mining services and mineral exploration and combined them into a unique, forward-thinking investment vehicle that provides investors exposure to both the “picks and shovels” and “blue sky” aspects of the mining industry.

Timberline has contract drilling subsidiaries in the western United States and Mexico and an exploration division focused on high-potential, district-scale gold projects. With its anticipated acquisition of a premier American underground mine contractor, Small Mine Development, Timberline will strengthen its position as an emerging, vertically-integrated resource company. Timberline is listed on the American Stock Exchange and trades under the symbol “TLR”.
