BUNKER HILL ANNOUNCES CHANGES TO ITS FINANCE TEAM AS PART OF CONCENTRATING ITS EXECUTIVE LEADERSHIP TEAM WITHIN THE USA

Bunker Hill Mining Corp. intends to hire a U.S.-based chief financial officer to concentrate its executive team within the United States, ensuring optimal alignment with its U.S.-focused corporate strategy.

Gerbrand Van Heerden has resigned from his position as CFO and corporate secretary, effective March 10, to return home to southern Africa and pursue mining opportunities there. He has been replaced by Bradley Barnett, a U.S. citizen, as interim CFO and corporate secretary, effective immediately. At the same time, the company is starting a formal search to retain a U.S.-based CFO. The company also announces the promotion of Mark McBride to vice-president, finance, effective immediately.

"Gerbrand has done a superb job at Bunker Hill, helping to strengthen our balance sheet, building robust financial systems capable of supporting our transition into an operating mining company and ensuring the restart of operations in the first half of 2026. As the company seeks to have its team located in the USA, it became clear that a transition was the best path for both Gerbrand and the company and we wish him well in his next endeavours," said Richard Williams, executive chairman.

"We welcome back Bradley Barnett as interim CFO and corporate secretary, respected as one of the founding members of the new, ex-Barrick management team that took up the Bunker Hill turnaround challenge in 2020. As a seasoned, hard-charging executive, well known to our team and completely familiar with the realities of U.S. commercial, government and capital markets, he is very well placed to support our ramp-up to commercial production, positive cash flow and growth thereafter. I also wish to take this opportunity to congratulate the tenacious and diligent Mark McBride on his well-deserved promotion to VP, finance, publicly."

Mr. Barnett brings more than 30 years of international business experience, including over 15 years in the global mining sector with leadership roles spanning finance, operations, sustainability and project development across North America, South America, Africa and Asia. He previously served as vice-president of sustainability at Bunker Hill Mining, where he played a key role in establishing the company's landmark relationship with the U.S. Environmental Protection Agency, which contributed to the restructuring of historical environmental liability terms, unlocking the restart opportunity.

Mr. Barnett has held senior leadership positions across the mining industry, including chief financial officer, CFO and managing director roles, and previously served as a managing director at Barrick Gold, responsible for creating value from its large portfolio of closed mine sites. He has also served as chief financial officer of Afghan Gold & Minerals Corp. and Central Asian Resources, U.S.-Afghan joint ventures that helped restart the mining industry in Afghanistan at a very challenging time for that country.

Mr. Barnett holds a bachelor's degree in economics from the University of California, Riverside. He will be included as a candidate in the search process to secure a long-term, U.S.-based CFO for Bunker Hill.
