FOR IMMEDIATE RELEASE

Timberline Closes $5-Million Offering, Fast-Track Exploration to Continue at Lookout Mountain

Coeur d’Alene, Idaho – March 3, 2011 – Timberline Resources Corporation (NYSE Amex: TLR; TSX-V: TBR) (“Timberline” or the “Company”) announced today that it has closed its $5-million offering of common stock.  Proceeds from the financing will be used to continue the Company’s aggressive exploration program at its Lookout Mountain Gold Project on the prolific Battle Mountain–Eureka Trend of central Nevada.

Timberline’s Executive Chairman Paul Dircksen stated, “Our recent work at Lookout Mountain strongly supports our belief in the potential for near-term development of a low capital, low operating cost, open pit, heap-leach gold mine.  This financing will allow us to maintain momentum with continued resource expansion drilling, along with exploration drilling at other priority targets at South Eureka.  We expect to release an updated NI 43-101 gold resource for Lookout Mountain within the next two weeks, as soon as current metallurgical tests are sufficiently complete, and we are also beginning work on a Preliminary Economic Assessment (PEA) of the project.  With anticipated gold production by early Q1 2012 at Butte Highlands, where development is completely funded by our JV partner, we believe that Timberline is exceptionally well-positioned for the ongoing bull market in gold.”

Lookout Mountain is the most advanced project within Timberline's 23 square-mile South Eureka land package and is located just a few miles from Barrick Gold Corporation's two-million ounce Archimedes / Ruby Hill mine. Lookout Mountain hosts significant oxide gold mineralization amenable to low-cost, heap-leach recovery, along with a smaller, high-grade, sulfide resource.

Timberline also announced today that it will be an exhibitor at the Prospectors and Developers Association of Canada (PDAC) International Convention, Trade Show and Investors Exchange at the Metro Toronto Convention Centre (South Building), March 6-9, 2011.  Timberline management invites shareholders and investors to visit Booth #3151 of the PDAC Investors Exchange, which is open to the public and free of charge.  Members of the Timberline team will be available to discuss progress and plans at its Lookout Mountain and Butte Highlands gold projects.

Shareholders and investors are also invited to view additional information, including the Company’s Corporate Presentation, at Timberline’s recently-updated web site at www.timberline-resources.com.
