Timberline Announces Positive Decision on Butte Highlands Mine Haul Road

COEUR D'ALENE, IDAHO--(Marketwired - Mar 18, 2015) - Timberline Resources Corp. (NYSE MKT:TLR)(TSX VENTURE:TBR) ("Timberline" or the "Company") announced today that the US Forest Service ("USFS") has completed its Environmental Assessment ("EA") and has released a Draft Decision Notice, which, when finalized, authorizes haulage by the Butte Highlands Joint Venture ("BHJV") and provides a route for mine support vehicles on two alternative routes from the proposed underground gold mine.

In announcing his decision, District Ranger David Sabo noted, "Upon thorough review of the EA and Montana Department of Environmental Quality's (MDEQ) Final Environmental Impact Statement for the Butte Highlands Joint Venture Mine, the effects of allowing BHJV to use either the west or north route is mitigated, allowing me to determine a Finding of No Significant Impacts for either route."

Based on his analysis, Mr. Sabo determined that both of the alternatives analyzed, Highland Road (west) and Roosevelt Drive (north), would not have significant effects on the quality of the human environment considering the context and intensity of impacts. Thus, an Environmental Impact Statement will not be required by the USFS. BHJV has proposed using the Highland Road (west) alternative.

The USFS final decision is expected following completion of a mandatory 45-day Federal objection period during which objections are allowable only from parties who have already submitted comments either during scoping or on the draft EA. Based on a previously released schedule, the USFS has scheduled a final decision on or around April 30, 2015, or, pending possible objections, in June 2015.

Kiran Patankar, Timberline's President and CEO, commented, "After a lengthy, detailed evaluation, we are very pleased with the decision released by the Forest Service, which will facilitate implementation of the mine plan proposed by BHJV and approved by the MDEQ. This represents another significant permitting milestone toward development of the Butte Highlands gold mine. We now look forward to the USFS completing their final decision and delivering the road permit. With the recent receipt of the positive Record of Decision by the MDEQ, and this positive decision by the USFS, our operating partner, Highland Mining, has begun evaluations to update plans for re-initiating mine development required for gold production. Timberline continues to support the efforts to move the Butte Highlands project forward to production."

Timberline owns a 50-percent carried-to-production interest in BHJV, which owns the Butte Highlands high-grade underground gold project. Timberline's joint venture partner is funding all mine development costs through to commercial production with Timberline's share of those costs to be repaid from proceeds of future mine production.

⁽¹⁾ Refer to Updated Technical Report on the Lookout Mountain Project, MDA, Effective March 1, 2013, Filed on SEDAR April 12, 2013

The Company's JV partner at Butte Highlands has decided that it may advance the project into production without first establishing NI 43-101 mineral resources supported by an independent technical report or completing a feasibility study. A production decision without the benefit of a technical report independently establishing mineral resources or reserves and any feasibility study demonstrating economic and technical viability creates increased uncertainty and heightens economic and technical risks of failure.

Cautionary note to United States Investors Regarding Estimates of Resources: This press release uses the terms "Measured Resources", "Indicated Resources", "Measured & Indicated Resources" and "Inferred Resources" We advise U.S. investors that while these terms are defined in and required by Canadian regulations under NI 43-101, these terms are not defined terms under United States Securities and Exchange Commission ("SEC") Industry Guide 7 and are normally not permitted to be used in reports and registration statements filed with the SEC. Under SEC Industry Guide 7 standards, a "final" or "bankable" feasibility study is required to report reserves, the three-year historical average price is used in any reserve or cash flow analysis to designate reserves and all necessary permits and governmental authorizations must be filed with the appropriate governmental authority. Investors are cautioned not to assume that any part or all of mineral deposits in these categories will ever be converted into reserves. "Inferred mineral resources" have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, except in rare cases. Investors are cautioned not to assume that all or any part of an inferred mineral resource exists or is economically or legally mineable. Disclosure of "contained ounces" in a resource is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute "reserves" by SEC Industry Guide 7 standards as in place tonnage and grade without reference to unit measures.
