Boise, Idaho – April 24, 2017 – Thunder Mountain Gold, Inc. (the “Company” or “Thunder Mountain”) (TSX-V: THM; OTCQB: THMG) announced today that they have selected SRK Consulting (U.S.), Inc. (SRK) to complete the Company`s South Mountain Preliminary Economic Analysis (PEA, or the Study).

The PEA will be prepared pursuant to NI 43-101 requirements suitable for submittal to TSX/OSC. SRK will help develop data gaps and provide guidance on the ongoing resource development work planned to start this field season. The Study will be equally weighted on the development of a new resource model and an optimized mine plan. Depending on the level of design detail associated with the proposed mill facility, SRK will either develop a PEA-level process flow sheet, or review and comment on designs by others. Facilities will have proposed locations on the Company`s private land holdings with sensitivity to any potential environmental issues. SRK will prepare the economics to a PEA-level of accuracy.

Once the development commences this spring, plans are for the Sonneman Level drift to be extended to the historic Texas ore zone, a distance of about 350 feet. Two core rigs are planned for extending the South Mountain resource, and testing extensions of the high-priority zones. One will begin on the DMEA 2 zone to complete the drilling initiated, but not completed, in 2013. A second core drill will focus primarily on the Texas zone to extend resources at depth beyond the current inferred resource area. In Addition, bulk samples will be collected for metallurgical test work, which will be orchestrated in part by SRK.

“We’re very encouraged with drill results at South Mountain completed in 2013,” said Mr. Collord, Thunder Mountain Chief Operating Officer. “Now that the underground has been safely and securely opened up, it shows tremendous down dip potential of these high grade zinc, silver, gold, copper, and lead zones. These high grade zones will be incorporated into the early years of the South Mountain mine plan. Given the associated economic upside of such a scenario, we plan to aggressively delineate the near-term economic extent of the mineralization at South Mountain, and we are glad to have SRK on board.”

Strategic Discussions Continuing with Potential Partners

Commenting on the appointment of SRK, Thunder Mountain Gold President and CEO Eric T. Jones said, “We are very pleased to have SRK engaged to assist us in the advancement of the South Mountain Project. Resource modeling and delineation work will start immediately, followed by the planned underground core drilling and additional drift rehabilitation once we have secured the required funding. We are actively working to secure the necessary capital to fully fund the PEA and associated development activities, and are currently in discussions with potential new investors and/or strategic partners.”

“Based on the work we have done to date at South Mountain, we already have the ability to move underground core drill rigs to identified exploration targets that are outlined in our model. We believe there is excellent geological potential to not only expand these major zones down-dip, but to also make additional South Mountain-type discoveries in the area,” Mr. Jones added.
