Timberline Announces Advanced Development Progress at Butte Highlands Gold Project

COEUR D'ALENE, IDAHO--(Marketwired - Sept. 4, 2013) - Timberline Resources Corporation (NYSE MKT:TLR)(TSX VENTURE:TBR) ("Timberline" or the "Company") announced today that its joint venture company, Butte Highlands JV, LLC ("BHJV"), has received required approvals from the Mine Safety and Health Administration ("MSHA") to access the Company's underground gold mine being developed at the Butte Highlands Gold Project in southwest Montana. BHJV received MSHA approvals for its ventilation plan, escapeway plan, and its mine rescue plan. Preparations are well underway, and, with this authorization, further underground development work may commence, including additional underground exploration drilling and groundwater monitoring and dewatering wells.

Timberline President and CEO Paul Dircksen commented, "We are pleased that BHJV has received these MSHA authorizations and is now able to commence a number of initiatives in preparation for gold production. With the publication of our Draft Environmental Impact Statement related to the Hard Rock Operating Permit anticipated within a few days, and the expectation that our remaining two permit issuances are on the horizon, our JV partner is actively conducting additional exploration and preparing for further development and subsequent production."

Preparations for additional development work at the Butte Highlands Gold Project include:

• Site administration personnel and the initial mining staff have been hired.
• Installation of one additional groundwater monitoring well has been completed, and a second monitoring well is underway.
• A contractor is mobilizing to install an additional dewatering well.
• An underground drilling contractor has mobilized equipment to the site in preparation for additional exploration and delineation drilling which will begin shortly.
• Site testing has been completed and plans finalized for installation of water discharge facilities per the requirements of the final MPDES water discharge permit issued and effective as of August 1, 2013.
• Plans are complete for development of a required secondary escapeway from the mine.
• Installation of power supply generators is complete.
• Procurement and delivery of mining and support equipment is ongoing.

Timberline owns a 50-percent carried-to-production interest in BHJV, which owns the Butte Highlands Gold Project where mining is expected to commence following the issuance of the final hard rock operating permit and the U.S. Forest Service approval of a road-use plan of operations for material haulage. Timberline's joint venture partner has and will continue to fund all mine development costs through to commercial production with Timberline's share of those costs to be repaid from proceeds of future mine production.

Cautionary Note

The Company clarifies that BHJV has decided to advance the Butte Highlands Gold Project into production without first establishing NI 43-101 compliant 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 associated with the Butte Highlands Project.
