Timberline Announces 30-Percent Increase to Its Measured and Indicated Gold Resource at Lookout Mountain

Page 3 of 4

Note: A qualified person has not done sufficient work to classify the historical estimates as current mineral resources. The Company is not treating the historical estimates as current mineral resources and the historical estimates should not be relied upon. The management estimates of the exploration target at Windfall was determined based on drill results and geologic modeling using polygonal grade shells with a 0.01 ounce per ton cut-off and a non-statistical average grade calculation based on a weighted average grade within each polygon. The estimate is conceptual in nature, and there has been insufficient exploration drilling to define a mineral resource that may be categorized as an indicated, measured, or inferred resource. It is uncertain if further exploration will result in the target being delineated as a mineral resource as defined in NI 43-101.

Other areas on the South Eureka property that contain drill-indicated gold and are prioritized for future exploration and drilling include Rocky Canyon, the Oswego structural zone, Pinnacle Peak, New York Canyon, Hoosac, Hamburg Ridge, Paige Corwin, and Secret Canyon.

Steven Osterberg, Ph.D., P.G., Timberline's Vice-President of Exploration, is a Qualified Person as defined by National Instrument 43-101 and has reviewed and approved the technical contents of this release. He has verified the drill results and other data disclosed in this news release, including sampling, analytical and test data. Field work has been conducted under his supervision. The Timberline sampling and analysis program included an industry standard QA/QC program. After logging and cutting or dividing the sample intervals in half, the samples were picked up by Inspectorate America Corporation and taken to their ISO-9001 certified assay lab in Sparks, Nevada for analysis. The samples were analyzed for gold using a standard 30g fire assay with an AA finish. Samples returning a gold value in excess of 3 ppm were re-analyzed using a 30g fire assay with a gravimetric finish.

The Lookout Mountain mineral resources were modeled and estimated by MDA by evaluating the drill data statistically, utilizing geologic interpretations provided by Timberline to interpret gold mineral domains on cross sections spaced at 50- to 100-foot intervals across the extents of the Lookout Mountain mineralization, rectifying the mineral-domain interpretations on level plans spaced at 10-foot intervals, analyzing the modeled mineralization geostatistically to aid in the establishment of estimation parameters, and interpolating grades into a three-dimensional block model. Mike Gustin is a Qualified Person as defined by National Instrument 43-101 and is responsible for the resource estimate.

About Timberline Resources

Timberline Resources Corporation is exploring and developing advanced-stage gold properties in the western United States. Timberline holds a 50-percent carried interest ownership stake in the Butte Highlands Joint Venture in Montana where gold production is targeted to commence in 2013. Timberline's exploration is primarily focused on the goldfields of Nevada, where it is advancing its flagship Lookout Mountain Project toward a production decision while exploring a pipeline of quality earlier-stage projects at its South Eureka Property and elsewhere. Timberline management has a proven track record of discovering economic mineral deposits and developing them into profitable mines.
