Thunder Mountain Gold, Inc.
Thunder Mountain Gold is advancing the South Mountain Project, a historic former Anaconda-developed polymetallic (Au-Ag-Zn-Cu-Pb) carbonate replacement deposit on private land in Owyhee County, Idaho, reporting measured & indicated and inferred resources but no reserves as of its most recent technical report. A 10,000-foot 2026 drill program is underway to expand the resource, alongside engineering work toward a PEA. The company also owns 100% of the Trout Creek gold exploration project in Nevada's Reese River Valley, adjacent to the Barrick-Newmont Nevada Gold Mines joint venture.

Lifecycle Milestones
A relative ranking of how closely this company matches the profile of juniors that have actually been acquired — not a probability, and not a reason to buy. Acquisitions are rare: only a few dozen significant deals happen a year across a universe of thousands of juniors, so even a high score here describes a long shot. The strongest signal the underlying research identifies — whether a major already holds a JV, earn-in, or 5–19.9% strategic stake — isn't tracked yet and is absent from this score.

Insiders, Investors & Smart Money
Notable shareholders and insiders whose involvement is worth knowing about, plus what we're seeing from institutional/large-investor activity.
Checked and nothing creditable could be confirmed. Thunder Mountain disclosed in December 2025 that MFD Investment Holdings SA, with Ocean Partners, had entered an options review phase aimed at near-term production at South Mountain, but the terms of that arrangement are not available and it could not be established as a funded earn-in or an equity position. Two small private placements closed in October 2025 and July 2026 with no participants named, and the company publishes no shareholder register. Institutional ownership is nil.
