Timberline Reports Additional High-Grade Gold Intercepts at Butte Highlands

COEUR D'ALENE, IDAHO--(Marketwire - 06/02/11) - Timberline Resources Corporation (TSX-V:TBR - News)(AMEX:TLR - News) ("Timberline" or the "Company") today announced additional results from underground drilling at the Butte Highlands Gold Project in southwestern Montana.Results reported today are from holes BHUG11-023 through BHUG11-033 in Timberline's on-going 86-hole, 49,500-foot (15,000-metre) underground diamond drill program which is designed for detailed delineation of the mineralization and for production planning purposes. Timberline has a 50-percent carried-to-production ownership interest in the project, which is currently in the development/permitting stage and is scheduled to commence gold production in early 2012.Nineteen intervals of gold grades greater than 0.10 ounce per ton (opt) (3.4 grams per tonne (g/t)) gold, including three intervals grading greater than 1.0 opt (34.2 g/t) gold were identified within the eleven holes reported today. Highlights include:

 

-- Hole # BHUG11-025: 12.3 feet (3.7 metres) grading 0.41 opt (14.0 g/t)
gold;
-- Hole # BHUG11-031: 6.8 feet (2.1 metres) grading 0.53 opt (18.2 g/t)
gold;
-- Hole # BHUG11-033: 12.0 feet (3.7 metres) grading 0.57 opt (19.5 g/t)
gold.

Paul Dircksen, Timberline's President and CEO, said, "We continue to see good continuity and gold grades from the underground drill program that support all of our earlier exploration work and the resulting advancement of the Butte Highlands Gold Project. Upon completion of the drill program, all data will be compiled into our mining plan in anticipation of scheduled 2012 production."All holes reported today were drilled in the Only Chance Block from Drill Station DS-2. Additional drill results for holes within this block are pending. The following table summarizes all drill intervals greater than 0.10 opt (3.4 g/t) gold.Current drill results from the Only Chance Block include:

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, April 20, 2011 and April 29, 2011.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.About Timberline ResourcesTimberline Resources Corporation is exploring and developing advanced-stage gold properties in the western United States.
