Timberline Resources Reports Additional Broad Zones of High-Grade Gold at Butte Highlands

Coeur d’Alene, Idaho – September 1, 2011 – Timberline Resources Corporation (NYSE Amex: TLR; TSX-V: TBR) (“Timberline” or the “Company”) today announced additional results from the 50,000-foot underground drill program at its Butte Highlands Joint Venture gold property in southwest Montana.

The drill program at Butte Highlands was designed for detailed delineation of gold 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. 

Drilling continues to hit broad intercepts of high-grade gold.  Twenty-five distinct intervals grading more than 0.10 ounce per ton (opt) (3.4 grams per tonne (g/t/)) gold, including four intervals grading more than 1.0 opt (34.3 g/t) gold were identified within the ten holes reported today.  Highlights include:

·

Hole # BHUG11-041: 32.1 feet (9.8 metres)   grading 0.21 opt   (7.2 g/t) gold;

·

Hole # BHUG11-042: 26.9 feet (8.2 metres)   grading 0.32 opt (11.0 g/t) gold;

·

Hole # BHUG11-043: 12.8 feet (3.9 metres)   grading 0.20 opt   (6.9 g/t) gold;

·

Hole # BHUG11-044: 28.8 feet (8.8 metres)   grading 0.21 opt   (7.2 g/t) gold;

·

Hole # BHUG11-047: 24.7 feet  (7.5 metres)  grading 0.23 opt   (7.9 g/t) gold;

·

Hole # BHUG11-048: 37.4 feet (11.4 metres) grading 0.23 opt   (7.9 g/t) gold, including

o

2.8 feet (0.8 metres) grading 2.31 opt (79.1 g/t) gold;

·

Hole # BHUG11-050: 32.6 feet (9.9 metres)   grading 0.30 opt (10.3 g/t) gold, including

o

4.6 feet (1.4 metres) grading 1.06 opt (36.3 g/t) gold;

·

Hole # BHUG11-050: 15.0 feet (4.6 metres)   grading 0.84 opt (28.8 g/t) gold, including

o

1.7 feet (0.5 metres) grading 1.47 opt (50.3 g/t) gold, and

o

3.8 feet (1.2 metres) grading 2.46 opt (84.3 g/t) gold.

Paul Dircksen, Timberline’s President and CEO, commented, “We continue to be pleased with the continuity of gold grades in the mineralized blocks throughout the main zone.  Our underground definition core drilling program continues to drive the advancement of our geologic and mining models toward the bulk sample planned for this fall and the anticipated ramp-up of gold production early next year.  As this project was conceived with gold prices at a fraction of recent levels, we are increasingly confident in the economic robustness of our planned operation at Butte Highlands.”

The following table summarizes all drill intervals greater than 0.1 opt (3.4 g/t) gold reported today:

* Troy ounces per ton (opt) and grams per tonne (g/t)

Note: The true widths of the intervals lengths are estimated to be approximately 75-percent of the reported interval length.

Holes BHUG11-040, 041, and 042 were drilled on the same azimuth at varying dips from Drill Station DS-4.  Hole BHUG11-040 passed through an historic stope (or mined out area) and thus returned no significant assays.   Holes BHUG11-041 and 042 intersected a mineralized zone approximately 65 feet and 145 feet, respectively, down dip from the stope.  Both holes correlate well with nearby drill holes, including previously-reported Hole BHUG11-039, which returned 14.7 feet (4.4 metres) grading 0.31 opt (10.5 g/t) gold, and others drilled in 1940.  More than 60,000 ounces of gold was produced at Butte Highlands in the 1940s from ore with an average grade of 0.60 opt.

Holes BHUG11-043, 044, and 045 were drilled on the same azimuth at varying dips from Drill Station DS-4.  Hole BHUG11-043 also encountered an historic stope, with Holes BHUG11-044 and 045 intersecting a mineralized zone approximately 85 feet and 185 feet, respectively, down dip from the stope.

Holes BHUG11-047, 048, 050, and 051 were all drilled from Drill Station DS-3, targeting in-fill areas between mineralized drill intercepts within the Old Mill and Only Chance blocks.  The results demonstrate excellent continuity within both blocks.

Holes BHUG11-043 and 050 also returned significantly mineralized intercepts at depth within areas not known to be mineralized, providing a new horizon for exploration at Butte Highlands.
