THUNDER MOUNTAIN GOLD FINALIZES $18 MILLION JOINT VENTURE AGREEMENT FOR THE SOUTH MOUNTAIN MINE

Boise, Idaho – November 12, 2012 - Thunder Mountain Gold, Inc. (the Company) (TSX-V: THM; OTCQB: THMG), is pleased to announce that it finalized the previously announced Joint Venture (JV) Agreement with ISR Capital, a Boise, Idaho based private equity group. The JV, called Owyhee Gold Trust LLC, will immediately begin advancing the exploration and development of the Company`s South Mountain Mine. ISR Capital can earn up to 75% participating interest in the project with an investment of $18 million.

Terms of the Agreement include a buy-in cash payment of $1 million to Thunder Mountain Gold, and a work commitment of $2 million no later than the end of 2013 to earn a 25% interest in the Project. An additional $5 million dollars are required to be spent into the project in the following three years under a plan to move the project through feasibility and into production. Thunder Mountain Gold has the option to participate on a pro-rata basis to retain 49% of the Project after the additional investment of $8 million dollars has been spent by ISR Capital, or can opt for a 25% participating interest upon the expenditure of the remaining additional $10 million earn-in by ISR Capital.

The $1 million buy in payment was initially secured by a convertible promissory note (the “Convertible Note”), announced on May 3^rd, 2012, as part of the financing agreement with ISR Capital This note was cancelled effective at the closing of the JV Agreement. The Convertible Note associated with the Project financing provided working capital to advance the Company’s projects, and achieve some of its near-term milestones while the JV Agreement was completed.

The project will be managed by a joint management team assembled by both companies. Work is due to start on the project immediately, with plans to enlarge both the Laxey and Sonneman tunnels to obtain a large metallurgical sample and conduct underground core drilling.  This work will yield the necessary information for an economic mine model that includes the nine, known, high-grade mineralized zones to aid in the development of a mining plan. It is estimated that the project will initially be a 400-ton-per-day underground operation that will produce multiple concentrates for sale to a smelter.

About South Mountain

The South Mountain project is located in southwest Owyhee County, Idaho approximately 70 air miles southwest of Boise, Idaho, and is 20 miles southeast of Jordan Valley, Oregon. The 100% owned South Mountain Mine was purchased by Thunder Mountain Gold in 2007. This flagship property was first mined in the late 1800s, and intermittently through the 1950s, with underground production from numerous mineralized zones with reported grades of 15% zinc (50% in certain zones), 10 opt silver,  0.10 opt gold, 2.0% copper, and 2.0% lead. A new gold target was identified early in their fieldwork at South Mountain., and additional exploration was conducted on this target which defined broad gold mineralization in an intrusive breccia that is considered part of a larger system responsible for both this and the high grade polymetallic ore shoots.

The Company’s land package at South Mountain consists of approximately 1,200 acres of mostly private land – both patented mining claims and leased ranch land.  In 2010, the Company completed a NI 43-101 Technical Report that incorporated all the new drill and sampling data.  This report was required as part of the Company’s listing on the TSX Venture Exchange in 2010.  The NI 43-101 can be reviewed on the Company`s website at www.thundermountaingold.com, or on www.SEDAR.com.
