Timberline Hits Highest-Grade Gold Intercept Ever Reported at Butte Highlands: 4.4 Metres of 232 g/t (14.5 Feet of 6.77 opt), Including 1.1 Metres of 946 g/t (3.5 Feet of 27.6 opt)

COEUR D'ALENE, IDAHO--(Marketwire - April 29, 2011) -Timberline Resources Corporation (TSX VENTURE:TBR)(NYSE Amex:TLR) ("Timberline" or the "Company") today announced more results from underground drilling at the Butte Highlands Gold Project in southwestern Montana. The highlight was Hole BHUG11-022 which returned 14.5 feet grading 6.77 ounces per ton (opt) gold, including 3.5 feet grading 27.6 opt gold, along with other mineralized intervals. This is the highest-grade gold assay ever reported at Butte Highlands.

Paul Dircksen, Timberline's President and CEO, stated, "We are very excited and encouraged with results from our underground drill program at Butte Highlands. The bonanza gold grades reported today support our expectation that Butte Highlands will be a robust profit generator for the Company."

The planned 86-hole, 49,500-foot (15,000-metre) program is designed for detailed delineation of the contained mineralization and for underground mine planning. Timberline holds a 50-percent interest in the project, which is under development and scheduled to begin gold production in early 2012.

Drilling to-date has focused on the upper portion of the "Old Mill Block", which has overall dimensions of approximately 275 feet (84 metres) along strike, 1100 feet (335 metres) down dip, and a mineralized thickness of 8 to 15 feet (2.5 to 4.5 metres). Other highlights from past and current drilling in the Old Mill Block at Butte Highlands include gold intercepts of:

  • 10 feet of 7.88 opt (3.1 metres of 269.9 g/t)
  • 33.6 feet of 1.65 opt (10.2 metres of 56.5 g/t), including 5 feet of 10.45 opt (1.5 metres of 357.9 g/t)
  • 14.3 feet of 2.37 opt (4.4 metres of 81.2 g/t)

Hole BHUG11-022 also returned two other intervals at grades exceeding 0.1 opt gold: 8.0 feet of 0.123 opt (2.4 metres of 4.2 g/t), including 1.6 feet of 0.313 opt (0.5 metres of 10.7 g/t); and 12.3 feet of 0.10 opt (3.8 metres of 3.4 g/t). The drill hole began within the boundaries of the Only Chance Block and crossed the structural zone between the Only Chance and Old Mill Blocks. The high-grade interval is likely from within this structural boundary while the reported lower grade intervals are well within the Old Mill Block. The high-grade interval was extracted at or near the contact between the Meagher dolomite and the skarn altered Wolsey formation. The interval is from within the fault gouge at the contact while the remainder of the intercept is within highly altered, faulted skarn material.

The following table summarizes drill intervals that exceed 0.1 opt gold within Hole BHUG11-022. This hole was drilled from underground Drill Station DS-2. (Intervals are reported relative to DS-2.)

Additional results from the ongoing program at Butte Highlands are expected shortly and will be reported by the Company as they are received. For previously-reported results from the underground drill program at Butte Highlands, please see Timberline's press releases dated April 6, 2011 and April 20, 2011.

Assays were also received for Holes BHUG11-018 through BHUG11-021, all of which were drilled from Drill Station DS-3 and none of which returned intervals of 0.1 opt gold or greater. BHUG11-018 was drilled at an angle of -70 degrees at the very eastern extent of the Old Mill Block. Holes BHUG11-019, 020, and 021 were all horizontal holes drilled at the very upper limits of the Old Mill Block. The lack of mineralization in these holes helps define the limits of the block.

Timberline holds a 50-percent interest in the Butte Highlands Joint Venture which is targeted to commence gold production in early 2012. Timberline's JV partner, Highland Mining, LLC is funding all project development costs, with Timberline's 50-percent share of costs to be paid out of proceeds from future mine production. A feasibility study has not been completed at Butte Highlands, and there is no certainty the proposed operation will be economically viable. Photos and videos of development progress at Butte Highlands, along with other additional project information, can be seen at Timberline's web site.

Butte Highlands is located within a favorable geologic domain that has hosted several multi-million ounce gold deposits including Butte, Golden Sunlight, Montana Tunnels, and Virginia City. The property was extensively drilled by Battle Mountain Gold, Placer Dome, ASARCO, and Orvana in the 1980s and 1990s.

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 photographing, 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 assay with an AA finish. Samples returning a gold value in excess of 10 ppm were re-analyzed using a 30g fire assay with a gravimetric finish.
