Coeur d’Alene, Idaho – September 29, 2011 – Timberline Resources Corporation (NYSE Amex: TLR; TSX-V: TBR) (“Timberline” or the “Company”) today announced significant assay drill results from its ongoing 30,000-foot drill program at the Lookout Mountain Project near Eureka, Nevada. These results are expected to substantially increase the Lookout Mountain NI 43-101 Measured and Indicated resource estimate(1) of 286,000 ounces of gold and the Inferred resource estimate(1) of 206,000 ounces of gold.
Paul Dircksen, Timberline’s President and CEO said, “We are very excited by these results that demonstrate continuity and expansion of our resource to the south of Lookout Mountain toward the South Adit area at higher grades than we have seen in the past. These gold grades, mineral continuity, and positive metallurgical characteristics achieved to date strongly support our stated objectives of increasing the gold resource at Lookout Mountain and advancing the project toward development of a low cost, run-of-mine heap leach gold producer.”
Timberline has, based on the positive drill results received to date, expanded its 2011 Drill Program for the Lookout Mountain Project and the greater South Eureka Property to include the addition of approximately 15,000 feet of drilling, for a total of 45,000 feet. This expanded drill program will focus on the following areas:
- Follow-up on the current drill results to substantiate potential resource expansion extending south of the Lookout Mountain resource area by approximately 1,000 feet;
- Follow-up on drill results in the South Adit Area with additional infill and extension drilling to expand the current strike extent, to serve as the basis for geologic modeling, and to generate a resource estimate for that area;
- Limited drill testing of targets outside of the Lookout Mountain area in order to initiate the generation of new resource centers within the South Eureka Property;
- Continue to drill test the west side of the Lookout Mountain resource area to further define the mineralized boundaries, establish potential pit boundaries, and define waste to ore boundaries.

The Company has two drills actively turning at South Eureka to accomplish the expanded 2011 drilling program. As part of this program, the Company is testing targets at the Windfall area on the east side of the South Eureka Property where the Company expects to generate additional resources.
Paul Dircksen, Timberline’s Executive Chairman, 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, including the insertion of certified standards and blank material into the assay stream. After logging and cutting or dividing the sample intervals in half, the samples were picked up by Inspectorate America Corporation and taken to their ISO-9001 certified assay lab in Sparks, Nevada for analysis. The samples were analyzed for gold using a standard 30g fire assay with an AA finish. Samples returning a gold value in excess of 3 ppm were re-analyzed using a 30g fire assay with a gravimetric finish. ALS Chemex, an ISO-9001 certified assay lab, provides check assays for mineralized intervals with gold assays above 100 ppb gold.
