Recent corporate activities include bylaw amendments, market making services agreements, private placements to raise capital, and board appointments. These actions support ongoing exploration and development efforts at the South Mountain Project.

• Thunder Mountain Gold announced a bylaw amendment and results of its annual general meeting in February 2026 [N6].
• The company entered into a market making services agreement in December 2025 to support liquidity [N7].

The company holds a significant polymetallic mineral project with updated resource estimates indicating substantial mineralization. Successful exploration and development could lead to commercial production, providing a foundation for future revenues. The company has demonstrated the ability to raise capital through private placements and has engaged in market making services to support liquidity. Corporate governance actions such as bylaw amendments and board appointments indicate active management. The lean operational structure may allow efficient use of capital during the exploration phase.

Thunder Mountain Gold has a history of net losses and an accumulated deficit exceeding $12 million, with no revenues reported to date. The company faces liquidity constraints as current liabilities exceed current assets and cash ratios are below 1. Mineral resource estimates include inferred resources with significant uncertainty and no assurance of conversion to reserves. The company operates in a highly regulated environment with risks related to permitting, environmental compliance, and market conditions. Failure to secure sufficient financing or to advance the project to commercial production could adversely affect the company's viability. The small team size may limit operational capacity.

Thunder Mountain Gold's moat is primarily based on its ownership and control of the South Mountain polymetallic mineral project, which has undergone multiple resource estimations and exploration phases. The company's long-standing presence and established property rights in a mining district with high-grade mineralization provide a potential competitive advantage. However, as an exploration-stage company without commercial production, the moat is limited by the inherent risks and uncertainties of mineral exploration, regulatory approvals, and capital requirements. The company's ability to advance the project through development stages and secure financing are critical to maintaining and potentially expanding its competitive position.
