Timberline Resources Drilling Identifies New Zone of Gold Mineralization at Eureka

COEUR D'ALENE, IDAHO--(Marketwired - Jan. 14, 2015) - Timberline Resources Corporation (NYSE MKT:TLR)(TSX VENTURE:TBR) ("Timberline" or the "Company") today announced the recognition of a new higher grade zone of gold mineralization at the Company's Eureka project in Nevada. Reverse circulation (RC) drill hole BHSE-171 intersected 25 feet of 0.144 ounces of gold per ton (opt) (7.62 meters (m) of 4.93 grams of gold per tonne (g/t)) within a longer 65 foot interval assaying 0.094 opt (19.82 m of 3.22 g/t) in the Lookout Mountain area. This hole was offset 140 feet from BHSE-152 (drilled in 2012) which first encountered the new zone but was not completed due to drilling difficulties. Additional drilling at Lookout Mountain and the previously announced drill program at the Windfall target is expected to recommence in the next two weeks.

Kiran Patankar, Timberline's President and Chief Executive Officer, commented, "BHSE-171 is significant for several reasons. First, the mineralization identified represents a new discovery at Eureka and validates the conceptual target identified by our technical team. Given our demonstration of continuity over 140 feet, it is reasonable to believe that we have not yet seen the center of the mineralization. With several thousand feet of untested strike extent, the Eureka project now has clear potential for a large underground bulk-mineable gold deposit."

Results from BHSE-171, as well as the previously-drilled BHSE-152, are presented in the table below:

BHSE-152 1,025 15.0 0.14 312.4 4.6 4.73
Notes:
(1) True widths of the drill intercepts have not been determined

The mineralization intersected in holes BHSE-171 and BHSE-152 is well correlated and represents a newly recognized zone of higher grade gold mineralization at depth associated with the existing resource at Lookout Mountain. The Company's current NI 43-101 compliant gold resource is defined over, and open beyond, a strike length of 4,000 feet. This new gold zone occurs within the favorable Dunderberg Shale near the brecciated contact with the Secret Canyon Formation and may represent a higher grade feeder system as recognized in many Carlin-type systems.

Drilling at Lookout Mountain is planned to resume in January and will initially include two additional holes to offset BHSE-171. Having now identified the mineralized zone through initial RC drilling, follow-up core drilling will sample the mineralized section to more accurately assess gold grade, stratigraphic and structural controls, and target geometry.

The program is also expected to include RC drilling at Windfall in order to test the strike extension and follow up on historic gold mineralization and the exploration target previously disclosed (December 17, 2014 press release).

Timberline's current gold resource estimate at Lookout Mountain, which was prepared by Mine Development Associates ("MDA") of Reno, Nevada, consists of:

Timberline's district-scale Eureka project is strategically located within the greater Eureka Mining District, just four miles from Barrick Gold's multi-million ounce Archimedes / Ruby Hill mine. The Eureka project features three distinct zones defined by structure and geochemistry and includes past-producing open pits, along with several untested zones and underexplored exploration targets. In addition to the estimated resources shown above, there is an exploration target totaling 185,000 - 200,000 ounces of gold at the Windfall structural trend that grades approximately 0.024 opt - 0.027 opt using a 0.010 opt cutoff. Detailed maps can be viewed at http://timberline-resources.com/main.php?page=194.

Note: A qualified person has not done sufficient work to classify the exploration target estimates as current mineral resources. The Company is not treating the exploration target estimates as current mineral resources and the exploration target estimates should not be relied upon. The management estimates of the exploration target at Windfall were 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.

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 news 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.

About Timberline Resources

Timberline Resources Corporation is focused on advancing and developing its 23 square mile Eureka project located within the Battle Mountain-Eureka gold trend in Nevada. The Company continues to advance the NI 43-101 resource of 508,000 ounces (M&I) and 141,000 ounces (Inferred) of gold at Lookout Mountain in addition to advancing the exploration target of 185,000 - 200,000 ounces of gold at the Windfall area into NI 43-101 compliance. Exploration potential across the project area occurs along three separate structural trends defined by distinct geochemical gold anomalies. The majority of the project area has yet to be drill tested. Historic production from heap leach mines took place at Lookout Mountain and Windfall mines, both located on the Company's Eureka project. Timberline also owns the Seven Troughs project in northern Nevada, known to be one of the state's highest grade, former producers, as well as a carried-to-production interest in the Butte Highlands high-grade underground gold project in Montana.

Timberline is listed on the NYSE MKT where it trades under the symbol "TLR" and on the TSX Venture Exchange where it trades under the symbol "TBR".
