Timberline Completes Talapoosa Option Payment

COEUR D'ALENE, IDAHO--(Marketwired - Apr 3, 2017) - Timberline Resources Corporation (OTCQB:TLRS)(TSX VENTURE:TBR) ("Timberline" or the "Company") announced today that on March 31, 2017 it paid the US$1 million cash payment to American Gold Capital US Inc. ("AGC"), a subsidiary of Gunpoint Exploration Ltd., in satisfaction of the cash option payment for its Talapoosa gold project in Lyon County, Nevada. The Company will also issue one million shares of the Company's common stock to AGC pending approval by the TSX-V. The cash and stock payments are made pursuant to the terms of the amended option agreement which permits the Company to acquire 100% of the Talapoosa gold project (the "Amended Option Agreement").

The original Option Agreement was amended in October, 2016 to extend the option exercise period until March 31, 2019, thereby allowing exploration and development related expenditures which are expected to further develop the Talapoosa gold project by increasing the gold resource and advancing the project to the feasibility stage.

Timberline's President and Chief Executive Officer, Steven Osterberg, commented, "We consider the completion of the initial option payment obligation to be an important and significant milestone in our efforts to further advance the Talapoosa gold project while testing the open extent of the resource and related initiatives to move to feasibility. With the strong investor demand for our previously announced non-brokered private placement (recently expanded to US$2.0 million), we are excited to advance the project forward during the 2017 field season. We appreciate the continued support of Gunpoint Exploration and American Gold Capital as significant and supportive shareholders of Timberline as we continue to advance Talapoosa."

The Talapoosa resource consists of 1,012,802 ounces (oz) of gold and 13,649,358 oz of silver in the Measured & Indicated Resources ("M&I") categories, with an additional 233,532 oz of gold and 2,172,766 oz of silver in the Inferred Resource category as detailed below:

A positive Preliminary Economic Assessment ("PEA") was completed on the Talapoosa project and released on April 27, 2015 by WSP Canada which envisioned the project as an open-pit, gold heap leach operation (See "Preliminary Economic Assessment on the Talapoosa Project, Nevada," effective April 27, 2015). The results of the PEA, using the base case price assumption of US$1,150/oz gold and US$16/oz silver, confirmed Talapoosa's economic potential, including:

• Estimated average annual production of 55,000 oz of gold and 679,000 oz of silver for 11 years
• Life of mine all-in sustaining costs of $599/oz gold (net of silver by-product at $16/oz silver price)
• Estimated US$209 million after-tax net cash flow
• After-tax NPV_5% of $136 million and 39% IRR at $1,150/oz gold price and $16/oz silver price
• Low initial capital requirement of $51 million.

Timberline's current focus will be on finalizing the on-going metallurgical studies and preparations for initial drill testing of the resource expansion target areas at Talapoosa and exploration on the adjacent Appaloosa zone (see Press Releases dated December 7, 2016, and January 31, 2017).

Cautionary Statements

The PEA is preliminary in nature and the economic analysis it presents is based, in part, on Inferred Resources that are considered too speculative geologically to have mining and economic considerations applied to them that would enable them to be categorized as Mineral Reserves. Estimates of Inferred Resources may not form the basis of feasibility or pre-feasibility studies, except in rare cases. There is no certainty that the economic forecasts contained within the PEA will be realized. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.

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. The PEA is not a definitive feasibility study and our projects currently do not contain any known proven or probable ore reserves under SEC Industry Guide 7 reporting standards. The results of the PEA disclosed in this press release are preliminary in nature and include Inferred Resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves and there is no certainty that the results of the PEA will be realized.
