Commenting on the results to-date, Timberline's President and CEO Steven Osterberg added, "The permeability and leach test results are encouraging and demonstrate that effective leaching of finely crushed material will enhance gold and silver recoveries. With the proven and cost-effective capability of HPGR crushing, and available particle separation technologies, we expect that the separate leaching of agglomerated fine and coarse fractions will result in combined gold and silver recovery levels at or above those estimated in the Talapoosa PEA. The potential has also been established to increase gold and silver recoveries through vat leaching of finely crushed material. We look forward to advancing this testing following additional drilling planned for collection of metallurgical samples."

PEA Disclaimer

The PEA is preliminary in nature and the economic analysis it presents is based, in part, on Inferred Resources that are considered too speculative geologically to have mining and economic considerations applied to them that would enable them to be categorized as Mineral Reserves. Estimates of Inferred Resources may not form the basis of feasibility or pre-feasibility studies, except in rare cases. There is no certainty that the economic forecasts contained within the PEA will be realized. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.

About Timberline Resources

Timberline Resources Corporation is focused on advancing district-scale gold exploration and development projects in Nevada, including its Talapoosa project in Lyon County where the Company has completed and disclosed a positive preliminary economic assessment. Timberline also controls the 23 square-mile Eureka project lying on the Battle Mountain-Eureka gold trend. At Eureka, the Company continues to advance its Lookout Mountain and Windfall project areas. Exploration potential occurs within three separate structural-stratigraphic trends defined by distinct geochemical gold anomalies. Timberline also owns the Seven Troughs property in northern Nevada, known to be one of the state's highest grade former producers.
