 Coeur d’Alene, Idaho – September 22, 2010 – Timberline Resources Corporation (NYSE Amex: TLR; TSX-V: TBR) (“Timberline” or the “Company”) today announced initial drill results from the first phase of its surface exploration drilling at the Butte Highlands Joint Venture Property.  

The initial part of Timberline’s seven-hole, 7,000 foot (2,134 meter) surface exploration program was designed to test the upper extension of the known Butte Highlands mineralization in the area of historic drill hole BH88-5, which was drilled by a previous operator and contained an intercept of 10 feet (3 metres) from a depth of 170 feet to 180 feet (52 to 55 metres) grading 0.31 ounces per ton gold (opt Au) (10.6 grams per tonne (g/t)). This phase of the surface drilling program consisted of two holes approximately 120 feet (37 metres) to the southeast of that historic drill intercept.

BHDDH 10-01 was designed to intercept the mineralized horizon approximately 120 feet (37 metres) to the southeast and at the same elevation as the historic intercept.  It penetrated the contact zone but encountered only weakly mineralized diorite where the mineralized horizon was expected.

BHDDH 10-02 was drilled from the same site at a steeper angle and was designed to intercept the mineralized zone 120 feet (37 metres) to the southeast and 130 feet (40 metres) down dip of the historic intercept.  It encountered mineralization in a 10-foot (3-metre) intercept from a depth of 262 feet (80 metres) to 272 feet (83 metres) grading 0.383 opt Au (13.1 g/t), including 4.4 feet (1.3 metres) grading 0.768 opt Au (26.3 g/t).  This intercept extends the mineralized zone identified by the historic intercept by approximately 120 feet (37 metres) downdip to the southeast.

Paul Dircksen, Timberline’s Executive Chairman, said, “The extension of mineralization is both encouraging and important, and will complement our understanding and planning for production at the Butte Highlands Joint Venture Property.  We will incorporate this new data into our future calculations and modeling of the mineralization.”

Timberline is continuing with the second phase of the surface exploration drilling program at Butte Highlands with four additional holes which will test targets outside the known area of mineralization and one additional hole in the eastern extent of the known mineralization.  Drill results will be released when the assay results have been received and evaluated, which is targeted for late October.

Paul Dircksen is a Qualified Person as defined by National Instrument 43-101 and has reviewed and approved the technical contents of this release. He has verified the drill results and other data disclosed in this news release, including sampling, analytical and test data.  Field work has been conducted under his supervision.  The Timberline sampling and analysis program included an industry standard QA/QC program.  After core logging and cutting the sample intervals in half, the samples were shipped to ALS Chemex Laboratories in Elko, Nevada for preparation.  The prepared pulps were then forwarded by ALS Chemex to their lab in Sparks, Nevada or their lab in Vancouver, BC Canada for analysis.  The samples were analyzed for gold using a standard 30g fire assasy with an AA finish.  Samples returning a gold value in excess of 10 ppm were re-anlayzed using a 30g fire assay with a gravimetric finish.
