Bunker Hill Wins ESG Developer/Explorer of the Year at the ‘Resourcing Tomorrow’ Investment Conference

Annual ESG Developer/Explorer of the Year Award

• The Mines and Money 'Resourcing Tomorrow' Conference was held in London from 27-30 Nov 2023; Europe's largest Mining, Energy and Resources Event dedicated to Global Sustainability Goals.
• The Award is judged on how well a Developer/Explorer has developed a long-term ESG Strategy.
• An effective ESG strategy is critical to enabling the restart of sustainable, profitable, and long-term mining operations within the Bunker Hill Superfund Site after 40 years of closure and rehabilitation.

Advancing on Plan and Budget Towards a North American ESG Milestone

• The sustainable restart of the Bunker Hill Mine is expected to be the first restart of mining operations within a Superfund Site since the start of that nationwide rehabilitation and clean-up program in 1969.
• Making use of rehabilitated infrastructure, the recycling of used mining equipment, existing permits, Idaho talent, local partnerships, and modern techniques/technology, the restart project advances on-time and on-budget; and is expected to offer between 230-250 new, modern, and long-term mining jobs to a local community hit hard by its closure in 1981.

TORONTO, Dec. 14, 2023 -- Bunker Hill Mining Corp., (TSX-V: BNKR) (OTCQB: BHHL) ("Bunker Hill" or the "Company") is pleased to announce that it was awarded the ESG Developer/Explorer of the Year Award at Mines and Money's 'Resourcing Tomorrow' Investment Conference in London on 30 Nov 2023.

"This special award not only recognizes the careful, thoughtful and imaginative work done by the whole Bunker Hill Team," said Sam Ash, Bunker Hill's CEO, "but also the awesome responsibility that is bestowed on all involved in the careful business of regenerating old mine sites to help de-risk the American critical metals supply chain".

BUNKER HILL ESG AND SUSTAINABILITY VISION

Inspired by those that deliver, promote, and educate industry best practice, the Company is expecting to restart safe, sustainable, and profitable mining at Bunker Hill in ways that enhance the quality of the environment during and after the conduct of active operations.

Working as one team, the Company seeks to balance the relentless but safe pursuit of the highest long-term financial returns from investment in mining operations with a deep-rooted commitment to delivering a positive legacy.

Working with our many partners and the applicable regulators, this not only involves responsible stewardship of every aspect of the physical environment, the forward-looking development of our diverse human resources, but also a deliberate effort to deliver positive and self-sustaining socio-economic impact to the local community.

THE ESG AWARD

The ESG award (a replica of a 19^th Century Welsh Coal Mining Lamp) sits in the office of Morgan Hill, Bunker's site-based Environment Manager and Women in Mining (USA) Rep. - a proud former graduate of Wallace High School and the University of Idaho (B.S Chemistry). She is also a granddaughter of a former Bunker Hill miner.

THE ESG-FOCUSED BUNKER HILL FUTURE - IT'S ABOUT MUCH MORE THAN MINING

The Company has developed a number of plans (illustrated above) expected to enable both the optimal sustainability but also the maximum positive impact in the community over the long term. These will each be further developed and executed in a prioritized sequence after mining operations have been restarted; and funded via the selective reinvestment of operating cash flow and 3^rd party partnership funding/support.

As with mining operations, so it will be with impact and sustainability projects, the Company will start small and then expand over time. This will be a transformational journey conducted at a sustainable and affordable pace.

Forward-looking statements are not comprised of historical facts. Forward-looking statements include estimates and statements that describe the Company's future plans, objectives or goals, including words to the effect that the Company or management expects a stated condition or result to occur. Forward-looking statements may be identified by such terms as "believes", "anticipates", "expects", "estimates", "may", "could", "would", "will", or "plan" or variations of such words and phrases. Since forward-looking statements are based on assumptions and address future events and conditions, by their very nature they involve inherent risks and uncertainties.

Cautionary Note to United States Investors Concerning Estimates of Measured, Indicated and Inferred Resources

This news release has been prepared in accordance with the requirements of the securities laws in effect in Canada, which differ from the requirements of U.S. securities laws. Unless otherwise indicated, all resource and reserve estimates included in this news release have been disclosed in accordance with NI 43-101 and the Canadian Institute of Mining, Metallurgy, and Petroleum ("CIM") Definition Standards on Mineral Resources and Mineral Reserves. NI 43-101 is a rule developed by the Canadian Securities Administrators which establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. The terms "mineral reserve," "proven mineral reserve" and "probable mineral reserve" are Canadian mining terms as defined in accordance with NI 43-101 and the CIM standards. Pursuant to subpart 1300 of Regulation S-K ("S-K 1300"), the U.S. Securities and Exchange Commission (the "SEC") now recognizes estimates of "measured mineral resources," "indicated mineral resources" and "inferred mineral resources." In addition, the SEC has amended its definitions of "proven mineral reserves" and "probable mineral reserves" to be substantially similar to the corresponding standards of the CIM. Investors are cautioned that while terms are substantially similar to CIM standards, there are differences in the definitions and standards under S-K 1300 and the CIM standards. Accordingly, there is no assurance any mineral reserves or mineral resources that the Company may report as "proven reserves," "probable reserves," "measured mineral resources," "indicated mineral resources" and "inferred mineral resources" under NI 43-101 will be the same as the reserve or resource estimates prepared under the standards adopted under S-K 1300. Investors are also cautioned that while the SEC now recognizes "measured mineral resources," "indicated mineral resources" and "inferred mineral resources," investors should not assume that any part or all of mineral deposits in these categories will ever be converted into reserves. Mineralization described using these terms has a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an "measured mineral resource," "indicated mineral resource" or "inferred mineral resource" will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, except in rare cases. Investors are cautioned not to assume that all or any part of an inferred mineral resource exists or is economically or legally mineable. Disclosure of "contained ounces" in a resource is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute "reserves" by SEC standards as in place tonnage and grade without reference to unit measures. Accordingly, information concerning mineral deposits contained in this news release may not be comparable with information made public by companies that report in accordance with U.S. standards.
