SECTION 3 - SECURITIES AND TRADING MARKETS

Item 3.02 Unregistered Sales of Equity Securities

On October 27, 2025, Thunder Mountain Gold, Inc. (the "Company") completed a non-brokered private placement (the "Private Placement") pursuant to which the Company issued 10,000,000 units (each, a "Unit") at a price of US$0.25 per Unit for gross proceeds of US$2,500,000. Each Unit consists of one common share of the Company (a "Common Share") and one-half of one common share purchase warrant (each whole warrant, a "Warrant"). Each Warrant entitles the holder to purchase one additional Common Share at a price of US$0.40 per share until October 24, 2027. The Company relied on the exemption from the registration requirements of the United States Securities Act of 1933, as amended (the "Securities Act") provided by Rule 506(b) of Regulation D and/or Section 4(a)(2) under the Securities Act for the issuance of the Units. Each purchaser in the Private Placement represented to the Company that the purchaser qualifies as an "accredited investor", as defined in Rule 501(a) of Regulation D under the Securities Act. The Common Shares and the Warrants comprising the Units and any additional Common Shares issuable upon exercise of the Warrants are and will be "restricted securities" under the Securities Act.
