TORONTO, July 06, 2023 - Bunker Hill Mining Corp. (the "Company") (CSE: BNKR, OTCQB: BHLL) is pleased to announce that Paul Smith has been appointed to its Board of Directors and as Chair of its new Growth Committee.

Richard Williams, Executive Chairman, commented: "I am excited and very proud to welcome Paul Smith to the Board of Directors of Bunker Hill and to his role as Chair of our new Growth Committee. As the former head of strategy for Glencore, and a highly respected M&A professional and financier, his technical expertise, extensive professional network, and track record will add essential strategic capabilities to our Board as we look to create growth and value beyond the restart of the Bunker Hill Mine."

Mr. Smith is a co-founder of Voltaire Minerals Partners, which provides innovative solutions to the critical minerals supply chain, and is also a Non-Executive Director at Seadrill (NYSE:SDRL), a global offshore drilling business for the oil and gas industry, and at Echion Technologies, the world's leading supplier of niobium-based anode materials. He was until recently Executive Chairman at Trident Royalties (LON:TRR), a mining royalty business.

Mr. Smith worked for Glencore plc ("Glencore") from 2011 to 2020 where, as Head of Strategy, his principal areas of focus were capital markets, M&A, and capital allocation. During this period, Glencore successfully completed numerous large scale corporate and capital markets transactions, most notably a $90 billion merger with Xstrata Plc.

FORMATION OF GROWTH COMMITTEE

Although the Company's current focus is the sustainable restart of its cornerstone asset - the Bunker Hill Zinc-Silver-Lead Mine, by the end of 2024 and the strengthening of the balance sheet, its medium-term strategy is to build from here a valuable portfolio of mines through M&A and subsequent asset optimization. To assist with this, the Company has established a special Growth Committee of the Board, chaired by Mr. Smith, to ensure optimal capital allocation in this endeavor. This committee will advise both the Executive team and the Board on the development of this growth strategy, the disciplined review of M&A opportunities and the timely execution of any deals.

ABOUT BUNKER HILL MINING CORP.
