Timberline Resources Corporation (OTCQB: TLRS) (TSXV:TBR) ('Timberline' or the 'Company') is pleased to report its initial mineral resource estimate for the Lookout Mountain gold deposit at its 100%-controlled Eureka Project in Nevada under Securities and Exchange Commission (SEC) Regulation S-K 1300, which is an SEC requirement for US mining projects governing the disclosure of mineral reserves and resources.

The Company has also filed the accompanying Technical Report Summary (TRS) under its profile on EDGAR and provided a link to the document on its website at www.timberline-resources.com.

Patrick Highsmith, Timberline's President and CEO commented, 'Our newly updated mineral resource estimate at the Lookout Mountain gold deposit reflects our first limited economic analysis. The Technical Report Summary documents a lot of work that has been accomplished over the last several years at Lookout Mountain, including solid initial metallurgical, environmental, and engineering studies. Advancing the deposit to pit-constrained resources has also identified opportunities for growth and optimization of the project towards economic viability. The recommendations from this study, as well as the exciting developments in the district, highlight the potential growth for both gold and silver at the Eureka Project.'

S-K 1300 is a relatively new regulation that requires SEC registrants with material mining operations, including those in the exploration and development stages, to provide certain disclosures about its mining activities in its SEC filings.

Growth Opportunities in and around the Lookout Mountain Resource

Conclusions and recommendations from the TRS include the observation that the resources reported are open along strike in both directions, as well as down dip. The possible extension of the Lookout Mountain deposit south through to the South Adit resource provides the best opportunity for near-term enhancement of project resources. In addition, there is excellent potential to add to the existing resources that lie west of the Ratto Canyon fault at the Lookout Mountain deposit.

The TRS recommends a program of infill drilling, resource-expansion drilling, further metallurgical testing, full three-dimensional geological modeling, and the completion of an Initial Assessment based on the current resources.

Timberline's exploration work at Eureka in recent years has been largely outside the resource area, but geologic modeling and extensive drilling at the adjacent Water Well Zone (WWZ) suggest that the two systems are related. Carlin type gold mineralization has been intercepted at more than 1,000 feet (300 meters) deep downdip from the Lookout Mountain deposit in the WWZ. That target remains open to the east and south.

Timberline drilling farther to the northeast from the WWZ target has also intersected silver-lead-zinc mineralization that is consistent with carbonate-replacement type deposits (CRD). A very large induced polarization (IP) chargeability anomaly occupies the corridor adjacent to and below the known Carlin-type gold and CRD-type drill intercepts. The IP anomaly has not been thoroughly drill tested.
