Thunder Mountain Gold Commences Underground Work at Their South Mountain Mine Joint Venture

BOISE, Idaho--()--Thunder Mountain Gold, Inc. (TSX-V: THM; OTCQB: THMG) (the Company), is pleased to announce that it has received approval from the U.S. Mine Safety and Health Administration (MSHA) for its underground exploration and development work at its South Mountain Project Joint Venture called Owyhee Gold Trust LLC (OGT).

OGT will immediately proceed with its plans that will enlarge the underground mine workings in both the Laxey (upper) and Sonneman (lower) levels of the mine. In this initial phase, OGT will obtain bulk metallurgical samples of blended ore from several of the nine mineralized zones on the Laxey Level, and establish underground drill stations for further core drill testing of the down-dip extensions of the larger ore zones. The goal of the underground drilling program is to determine the depth and grade of these ore zones; verify the minable resource that can potentially be mined from the two levels; and expand the current 43-101 compliant resource. The bulk sampling program will provide samples for mill process and design that will suit the polymetallic ore.

The underground development work is being done by Widman Contractors, Baker City, Oregon. Widman has extensive underground mining experience throughout the western U.S., including work for Newmont Mining, Barrick, Independence and others in Nevada. They will be driving a minimum 10-foot by 10-foot dimension tunnel along the Laxey and Sonneman Levels. They currently have a crew of eight miners at South Mountain.

Additionally, the Company`s JV has hired Michael S. Smith, P.E. as Chief Engineer and Project Manager. Mike is a professional engineer with certifications in civil engineering, mine engineering, and land surveying, and has 35 years of experience in mining projects throughout Nevada including the Jerritt Canyon Mine; The Cortez Gold Mines; The Phoenix Property; The Getchell Mine; and The Coeur Rochester Mine.

Eric Jones, President and CEO of Thunder Mountain Gold said of the hire, “Thunder Mountain is excited to move forward with the underground work and fortunate to have an engineer of the caliber as Mike to help with management of the JV project. His experience and knowledge adds a lot of value to our South Mountain Project and will help in moving the project toward production.”
