Bunker Hill Silver (OTCQB: BHLL) announced Gary Thompson’s resignation from its board of directors, effective November 10, 2026.
The mutually agreed departure supports Thompson’s other commitments and, the company said, its goal of maintaining an appropriate mix of independent and executive directors while preparing for a potential U.S. national securities exchange listing. His departure was not the result of any disagreement with the company.
The Governance and Nominations Committee has begun searching for two additional independent directors and expects an appointment in the coming months. Thompson joined the board when the arrangement with Silver47 Exploration was completed. A U.S. national exchange listing is not guaranteed.

To support ramp‑up and exploration, Bunker Hill has secured a US$10 million concentrate prepayment facility with Ocean Partners and drawn US$1 million under its standby facility with Teck.

Bunker Hill Mining (OTCQB: BHLL, TSX: BNKR) has completed the first production stope blast at its 100%-owned Bunker Hill Mine in Idaho, marking a transition from redevelopment to sustained underground production and supporting its plan to reach commercial production by the end of 2026.
The mine is ramping up toward a targeted 1,800 tonnes-per-day operation using transverse longhole stoping with paste backfill, which mixes filtered mill tails with cement and eliminates the need for a surface tailings facility, aligning with the company’s environmental priorities.
Bunker Hill also reported four consecutive years without a lost-time incident and one full year without a recordable safety incident at the mine, highlighting its safety-focused culture as underground mining and processing operations continue to advance.
