Timberline Resources Acquires Silver, Gold, Zinc Skarn Project


SPOKANE, Wash., April 12, 2005 (PRIMEZONE) -- Timberline Resources Corporation (Pink Sheets:TBLC) announced today that it has entered into a Mineral Lease Agreement to acquire the Downeyville Project, located in Nye County, Nevada. The Downeyville property consists of 21 unpatented lode mining claims located approximately ten miles north of the Paradise Peak Mine and within a 30-mile radius of four other Timberline properties. The lease calls for Timberline to make annual payments of $10,000 and perform $50,000 of exploration work annually. In addition, the lessor retains a 3% Net Smelter Return royalty, which is reduced to a 1% NSR if Timberline performs $150,000 of exploration work prior to October 2008 and makes an additional cash payment of $150,000 to the lessor.

Twenty-three rock chip samples were collected by Timberline geologists from mapped structures and existing dumps on the property. Nine of these samples returned assay values ranging from strongly anomalous to ore-grade for zinc, silver and gold. Assay values for selected samples include:



                     Silver             Gold              Zinc
                (ounces per ton)   (ounces per ton)        (%)

 Sample DX-20         6.62              0.041              5.89
 Sample DX-21         3.81              0.034             10.20
 Sample DX-23         5.61              0.061             26.00

Strongly oxidized shear controlled and replacement-type mineralization occurs throughout the claim group. An airborne geophysical magnetic high to the southwest under alluvial cover could represent a buried intrusive related to the distal base and precious metal mineralization found on the Downeyville claims. The high zinc grades and consistently elevated gold and silver values accompanied by pyrrhotite, magnetite, and tremolite-actinolite indicate a proximal gold skarn system, similar to the Cove-McCoy Mine.

The Downeyville property is one of five precious metal targets the Company has acquired in Nevada's Walker Lane mineral belt. Mapping and sampling by Timberline has identified drill targets on all five properties. The Company is currently seeking joint venture partners for these prospects.
