Coeur d'Alene, Idaho - September 15, 2015 - Timberline Resources Corporation (NYSE MKT: TLR; TSX-V: TBR) ("Timberline" or the "Company") is pleased to announce that it has signed a non-binding Letter Agreement ("Letter Agreement") with an effective date of September 13, 2015, pursuant to which Waterton Precious Metals Fund II Cayman, LP (together with its subsidiaries and affiliated and associated entities, "Waterton") has offered to acquire all of the issued and outstanding shares of Timberline's common stock for cash consideration of US$0.58 per Timberline share (the "Transaction"). The structure of the proposed Transaction remains to be determined, and the consummation of the Transaction is subject to completion of due diligence, execution of definitive agreements, Board and regulatory approvals, and other customary closing conditions.

In connection with the Transaction, Timberline and Waterton have agreed that Waterton will subscribe for 1,331,861 common shares of Timberline on a private placement basis at a price of US$0.375 per share for total proceeds of US$499,447.87 (the "Private Placement"). This represents approximately 9.9% of Timberline's outstanding common shares after giving effect to the Private Placement. The Private Placement is binding and expected to close no later than September 23, 2015, subject to the satisfaction of certain regulatory requirements, but is not contingent on completion of the Transaction. Waterton will have the right to maintain its pro rata ownership position in Timberline in the event the Transaction is not completed.

Kiran Patankar, President and CEO of Timberline commented, "We are very pleased to announce this agreement with Waterton, which addresses Timberline's immediate financing requirements and, subject to completion of the Transaction, also provides cash consideration to Timberline shareholders at a significant premium to the current trading price in a difficult market for junior gold companies."

Cheryl Brandon, Partner and head of Investment Management of Waterton's investment adviser said, "We are very pleased to have reached an agreement with the board and management of Timberline. The acquisition of Timberline's assets in Nevada will enhance Waterton's existing portfolio of high-quality development properties in the region."

Proposed Transaction Highlights

• Acquisition price of US$0.58 per share represents a 76% premium to Timberline's closing price of US$0.33 per share on September 11, 2015 and a 79% premium to the Company's 20-day Volume Weighted Average Price ("VWAP")
  
• The cash consideration being provided by Waterton offers Timberline shareholders certainty in a difficult market environment for gold exploration and development companies
  
• The Private Placement financing of US$499,447.87 significantly de-risks the Company financially in the event the Transaction does not proceed
  
• Waterton has a proven recent track record of acquiring Nevada gold assets and has a strong strategic interest in advancing both the Talapoosa and Eureka projects
