Timberline Resources Announces Drill Results from Its Lookout Mountain Gold Project

COEUR D'ALENE, IDAHO--(Marketwire - Sept. 8, 2011) - Timberline Resources Corporation (TSX VENTURE:TBR)(NYSE Amex:TLR) ("Timberline" or the "Company") today announced assay results from the first 13 holes of the ongoing 30,000-foot drill program at its flagship Lookout Mountain Gold Project along the Battle Mountain - Eureka Trend of central Nevada.

Lookout Mountain is the most advanced project within Timberline's 23 square-mile South Eureka land package, located just a few miles from Barrick Gold Corporation's two-million ounce Archimedes / Ruby Hill mine. South Eureka contains sediment-hosted gold mineralization, most of which is amenable to low-cost, heap-leach recovery. Timberline's current resource estimate at Lookout Mountain consists of 286,000 ounces of gold in the Measured & Indicated Resource(1) categories and 206,000 ounces of gold in the Inferred Resource(1) category, utilizing a cut-off grade of 0.006 ounces of gold per ton (opt) (0.21 grams per metric tonne (g/t)) for oxide material and 0.030 opt (1.03 g/t) for sulfide material.

South Eureka also includes a pipeline of earlier-stage projects that feature past gold production, historic gold estimates, and/or mineralized drill intercepts along three extensive mineralized trends.

Timberline's planned $3 million exploration and drilling program for 2011 is designed to include:

  • Drilling to expand and upgrade the NI 43-101 resource at Lookout Mountain both laterally and along strike.
  • Drilling known mineralized zones, including some with historic gold resources, with an objective of bringing them into NI 43-101 compliance.
  • Initial drill testing of large, prioritized, structural and geochemical targets at various locations across South Eureka.
  • Additional metallurgical testing and engineering studies to further define process characteristics of the mineralization.
  • Commencement of permitting activities and environmental baseline studies necessary for a production decision.

Paul Dircksen, Timberline's President and CEO, said, "These initial results support our program by: (1) extending the Lookout Mountain resource into the South Adit area, and (2) demonstrating resource continuity in the southern portion of Lookout Mountain. We are also pleased with initial drill results to the west of the resource as we await additional drilling and subsequent assays from that area. Meanwhile, sodium cyanide (NaCN) shake tests continue to demonstrate excellent gold recoveries, supporting our belief in the potential to develop a low cost, run-of-mine, heap leach operation at Lookout Mountain."

The following table summarizes significant drill intercepts within three categories:

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.
