Timberline Extends High-Grade Zone at Butte Highlands by Drilling 51.8 Feet (15.8 Metres) Grading 0.43 Ounces of Gold per Ton (14.6 Grams per Tonne)

COEUR D'ALENE, IDAHO--(Marketwire - Nov. 10, 2011) - Timberline Resources Corporation (TSX VENTURE:TBR)(NYSE Amex:TLR) ("Timberline" or the "Company") today announced continued drilling success from its 50,000-foot underground core drill program at the Butte Highlands Joint Venture Gold Project in southwestern Montana.

Paul Dircksen, Timberline's President and CEO, commented, "We are especially impressed with the broader zones of consistent high-grade gold in the mineralized blocks at Butte Highlands. These are exceptional results that extend the deposit while improving the quality and reliability of our geologic model and our mine model as we move toward production."

The drill program at Butte Highlands was designed for detailed delineation of gold mineralization and for production planning purposes. Drilling continues to expand and in-fill the deposit with broad intercepts of high-grade gold. Fifteen distinct intervals grading in excess of 0.10 ounces per ton (opt) (3.4 grams per tonne (g/t)) gold were identified within the six holes reported today. Highlights include:

Hole # BHUG11-049: 7.5 feet (2.3 metres) grading 0.50 opt (17.0 g/t) gold;
13.6 feet (4.1 metres) grading 0.36 opt (12.3 g/t) gold, including
3.6 feet (1.1 metres) grading 1.18 opt (40.3 g/t) gold;
13.0 feet (4.0 metres) grading 0.29 opt (9.9 g/t) gold, including
2.2 feet (0.7 metres) grading 1.57 opt (53.8 g/t) gold.
The assay intervals reported in BHUG11-049 extend the mineralized envelope approximately 120 feet down dip from a previously-reported interval of 2 feet grading 1.99 opt gold.
Hole # BHUG11-052: 31.5 feet (9.6 metres) grading 0.15 opt (5.0 g/t) gold;
10.2 feet (3.1 metres) grading 0.49 opt (16.8 g/t) gold, including
2.0 feet (0.6 metres) grading 2.00 opt (68.5 g/t) gold;
8.6 feet (2.6 metres) grading 0.30 opt (10.2 g/t) gold.
Hole # BHUG11-053 22.8 feet (6.9 metres) grading 0.33 opt (11.4 g/t) gold;
8.5 feet (2.6 metres) grading 0.12 opt (4.0 g/t) gold.
Hole # BHUG11-054: 10.2 feet (3.1 metres) grading 0.10 opt (3.3 g/t) gold;
10.8 feet (3.3 metres) grading 0.11 opt (3.7 g/t) gold.
Hole # BHUG11-058: 51.8 feet (15.8 metres) grading 0.43 opt (14.6 g/t) gold, including
5.0 feet (1.5 metres) grading 1.03 opt (35.4 g/t) gold;
13.1 feet (4.0 metres) grading 0.11 opt (3.3 g/t) gold;
38.7 feet (11.8 metres) grading 0.14 opt (4.6 g/t) gold.
These holes were designed to test deeper portions of the Only Chance Block indicated by historic drilling. These holes encountered wide zones of continuous high grade gold with few sub-grade values within. The intercepts are approximately 350 feet (107 metres) apart representing the same zone and approximately 350 feet (107 metres) down dip from a previously reported interval in BHUG11-036 of 25.8 feet (7.9 metres) of 0.17 opt (5.82 g/t) gold.
Hole # BHUG11-078: 22.2 feet (6.8 metres) grading 0.29 opt (10.0 g/t) gold;
60.1 feet (18.3 metres) grading 0.14 opt (4.7 g/t) gold.

BHUG11-078 was successful in extending the mineralized Gold Excell Block both laterally and approximately 165 feet (50 metres) up dip from previous intercepts.

Note: The true widths of the intervals lengths are estimated to be approximately 75-percent of the reported interval length. Grades are measured in troy ounces per ton (opt) and grams per tonne (g/t).

The Butte Highlands Joint Venture 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.
