Timberline Successfully Completes Drill Program at Lookout Mountain

Step-Out Drilling Results Indicate Resource Expansion Opportunity

COEUR D'ALENE, IDAHO--(Marketwire - Feb. 17, 2011) - Timberline Resources Corporation (TSX VENTURE:TBR)(NYSE Amex:TLR) ("Timberline" or the "Company") is pleased to report the successful completion of its 2010 exploration program and the receipt of all assays for the drilling at its Lookout Mountain Gold Project located within the prolific Battle Mountain–Eureka Trend of Central Nevada. Significant drill intervals of gold mineralization, with continued favorable gold recoveries, within the southern resource area indicate the potential for resource expansion, increasing grade, and additional untested extensions to the south.

Timberline's Executive Chairman and Vice-President of Exploration, Paul Dircksen stated, "With each additional set of assay results received, we continue to be pleased with the consistent assay results and their indicated gold recoveries at our Lookout Mountain Project. The results from our completed drill program support our view for the potential near-term development of a low-capital, low-cost, open pit operation with run-of-mine heap-leach gold recovery processing. In addition to validating our current resource, a number of our drill intercepts indicate an opportunity to expand the resource with continued drilling. We intend to now complete our 43-101-compliant resource, continue our bench scale metallurgical test work, begin our Preliminary Economic Assessment (PEA), and plan a follow-up drill program for this spring with a goal to expand the existing resource at Lookout Mountain and to test other prospective targets within the South Eureka Property."

Significant drill intercepts were found in holes numbered BHSE-068 and BHSE-070 (see table below), which were drilled as offset holes 150 and 350 feet south of hole number BHSE-062, which had an intercept of 235 feet of 0.036 opt (71.6 metres of 1.22 g/t) gold. (See Timberline Press Release of February 8, 2011 http://timberline-resources.com/main.php?page=190&press=139) Due to poor ground conditions, the Company was forced to abandon hole number BHSE-070 in mineralization. As a result, the mineralized zone at the southern portion of the Lookout Mountain resource area remains open along strike and at depth, potentially increasing the contained gold ounces by increasing the size and grade of the gold mineralization.

All data is currently being compiled, cross-sections are being generated, and grade shells are being constructed to enable Mine Development Associates (MDA) of Reno to complete a NI 43–101 compliant resource at Lookout Mountain. Timberline expects to release the updated resource in early March.

Significant drill results and gold recoveries include:

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. Lookout Mountain hosts significant oxide gold mineralization amenable to low-cost, heap-leach recovery, along with a smaller, high-grade, sulfide resource. In September 2010, Timberline embarked on a $2.5-million South Eureka work program, primarily designed to complete a NI 43-101 compliant resource estimate at Lookout Mountain. The program has included 7,500 feet of core drilling, 30,000 feet of reverse circulation drilling, extensive metallurgical testing, and detailed geological mapping to better understand mineralization controls and outline additional drill targets. 

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 logging and cutting or dividing the sample intervals in half, the samples were picked up by Inspectorate America Corporation and taken to their 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.
