Timberline Prepares for Initial Drill Program at Snowstorm
SPOKANE, Wash., Sept. 15, 2005 (PRIMEZONE) — Timberline Resources Corporation (Pink Sheets:TBLC) announced today that it has retained a drilling contractor for a core drill program at the Snowstorm Project in north Idaho’s “Silver Valley”. Timberline can earn a 49-percent interest in the Snowstorm Project from Hecla Mining Company (NYSE:HL) by completing a Phase I exploration program with minimum expenditures of $250,000 by October 2006.
The Snowstorm Project features the Snowstorm Mine, a small but highly profitable operation from the early-1900s that produced 800,000 tons of ore averaging 4-percent copper and 6 ounces per ton (oz/t) silver. A dump sampling program earlier this field season returned ore grade assays of 0.9 to 2.5-percent copper and 0.5 to 3.0 oz/t silver from multiple locations along a nearly 1.5-mile strike length. These results, along with geologic mapping and fieldwork, have demonstrated the potential for a world-class stratabound copper-silver deposit at Snowstorm similar to those found at Troy, Rock Creek, and Montanore, high-tonnage ore bodies with a combined average grade of 0.74-percent copper and 1.73 oz/t silver.

M2 Exploration of Coeur d’Alene, Idaho has been contracted by Timberline to drill at Snowstorm. Drilling is expected to commence later this month. Specific drill plans will be announced in a subsequent press release.

Timberline also announced today that it has closed a modest financing through Company insiders and accredited investors with a combination of equity and loans. These funds will be used for Snowstorm drilling.

Timberline Resources Corporation is a mineral exploration company focused on the cost-effective acquisition and exploration of promising mineral properties in the western United States. Timberline’s flagship property is the Snowstorm Project in north Idaho’s “Silver Valley,” where it can earn a 49-percent interest from Hecla Mining Company in a bulk-tonnage stratabound copper-silver target, potentially similar to well-known deposits in western Montana. Timberline has less than 7.3 million shares outstanding and its common stock is quoted on the OTC Market under the symbol “TBLC”.
