COEUR D'ALENE, Idaho, Oct. 29, 2010 (GLOBE NEWSWIRE) -- Timberline Resources Corporation (NYSE Amex:TLR) (TSX-V:TBR) ("Timberline" or the "Company") today announced final drill results for its 2010 surface exploration drill program at the Butte Highlands Joint Venture Property in Montana.

The seven hole drill program included three holes within the mineralized envelope currently under development, while four holes were drilled outside the envelope to test potential eastern extensions of the mineralized zone.

Drill hole BHDDH10-07 returned a significant intercept of 43.2 feet averaging 0.82 ounces per ton (opt) (13.2 metres at 28.1 grams per tonne (g/t)) gold including 2.2 feet grading 15.24 opt (0.7 metres of 521.9 g/t) gold.

This hole indicates a bonanza grade zone within the current mineralized area and could represent some of the initial production, which is expected to commence in Q3/Q4 2011. Additional drill holes within the zone demonstrate a strike distance of continuous bonanza gold grades of nearly 200 feet (61 metres) and include the following historical drill results:

This zone will be in-fill drilled from underground drill stations during the Butte Highlands Joint Venture Definition Drill Program to commence during the final quarter of this year.

The results from the first two holes in the Butte Highlands exploration drill program were reported earlier in the Company's press release dated September 22, 2010 and included drill hole number BHDDH10-01 which contained no significant mineralization, and drill hole number BHDDH10-02 which had a mineralized interval of 4.4 feet grading 0.77 opt (1.3 metres of 26.4 g/t) gold.

Exploration drill holes numbered BHDDH10-03 thru BHDDH10-06 were drilled to the east of the current mineralization, and although they did not return potentially economic grades, they did return several intervals of gold mineralization. These results will assist in planning of future exploration in the area. The material results in these holes are as follows:

Timberline's Executive Chairman, Paul Dircksen, stated, "We are extremely pleased with these drill results. The impressive gold grades in drill hole number BHDDH10-07 and the nearby high-grade intervals demonstrate the grade continuity of one of the high-grade portions of the Butte Highlands deposit. We are confident that our final in-fill drilling will continue to enhance the economics of the project."

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.
