Timberline Expands Presence in Nevada with Acquisition of Seven Troughs Epithermal Gold District

COEUR D'ALENE, IDAHO--(Marketwire - June 21, 2012) - Timberline Resources Corporation (TSX VENTURE:TBR)(NYSE Amex:TLR) ("Timberline" or the "Company") today announced the purchase of a large block of patented and unpatented mining claims comprising essentially the entire Seven Troughs gold mining district near Lovelock in Pershing County, Nevada.

The purchased property package covers 3,900 acres, consisting of sixty-four (64) patented and seventy-six (76) unpatented lode mining claims, all of which are under a long-term lease agreement, along with one hundred sixty-two (162) additional unpatented lode mining claims. The leased portion of the property package requires no lease payments or work commitments from Timberline.

The Seven Troughs district is recognized as yielding some of the highest gold production grades in Nevada history. Small-scale operations from the district in the early 20^th century reportedly produced about 150,000 tons of ore grading approximately 1.20 ounces of gold per ton (opt) (41.1 grams per tonne) (g/t) and 4.0 opt (137 g/t) silver.

Exploration data generated since 1977 by several operators including Newmont and Teck includes 111,565 feet (34,005 metres) of rotary drilling from 159 holes, 11,501 feet (3,505 metres) of core from five holes, extensive geochemical and geophysical data, and surface geologic mapping. A considerable database of district activity is included in the purchase and is expected to contribute to the rapid development of several drill targets.

Paul Dircksen, Timberline's Chief Executive Officer, said, "This acquisition provides us with an excellent exploration opportunity for nominal cost. We believe the Seven Troughs district has the potential to host a large precious metals system similar to the high-grade gold and silver veins of Japan's world-renowned Hishikari epithermal gold mine."

Significant high-grade drill intercepts from the modern era (since 1977) of Seven Troughs exploration include:

	Drill Hole Number		Length (Feet)		Gold (opt)		Length (metres)		Gold (g/t)
	ST-7		25		2.00		7.6		68.5
	NST-5		5		0.56		1.5		19.2

This high-grade material is enhanced by lower-grade drill intercepts and surface trenching samples from other areas of the district that demonstrate the potential of the system. A few of those results, also from the modern era of Seven Troughs exploration, include:

	Drill Hole Number		Length (Feet)		Gold (opt)		Length (metres)		Gold (g/t)
	S-8		135		0.03		41.2		1.03
	SR-4		60		0.06		18.3		2.05
	SR-18		35		0.04		10.7		1.37
	SR-11		25		0.04		7.6		1.37
	Trench Sample		Length (Feet)		Gold (opt)		Length (metres)		Gold (g/t)
	B-6		225		0.02		68.6		0.68
	YD-2		280		0.01		85.3		0.34

The purchased property includes all of the Seven Troughs District holdings of CIT Microprobe Holdings LLS (California Institute of Technology) (CIT). The property package had been part of an estate that was donated to CIT. Terms of the purchase agreement include a cash payment of $50,000 from Timberline and a 2-percent NSR production royalty reserved to CIT with a standard royalty buy down clause.

Mr. Dircksen continued, "It is uncommon for mineral exploration companies to acquire a substantial Nevada gold district with meaningful past production and promising drill intercepts on such favorable terms. Timberline is under no obligation to make expenditures on the property in the near-term. The Seven Troughs acquisition is an excellent fit with our business plan to explore and develop a pipeline of high-potential gold projects in the western United States."
