Marketing Announcement

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, Ontario (December 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.

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 3rd 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.

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. Although these statements are based

on information currently available to the Company, th e Company provides no assurance that actual results will

meet management’s expectations. Risks, uncertainties, and other factors involved with forward -looking

statements could cause actual events, results, performance, prospects and opportunities to differ materially from

those expressed or implied by such forward-looking statements.

Forward looking statements in this news release includes, but are not limited to : the Company’s intentions

regarding its objectives, goals or future plans and statements, including the restart of the Bunker Hill Mine and the

timing, budget, profitability and long-term sustainability of mining operations; operational objectives associated

with the expected restart of active mining operations, including local, socio-economic and environmental benefits,

and the Company developing and executing further development plans ; revenue potential opportunities from

mining and the sale of ore; increases in cash flow; and the Company’s seeking other value -creating opportunities

to restart mining operations at the Bunker Hill Mine, including third-party partnerships and funding. Factors that

could cause actual results to differ materially from such forwar d-looking statements include, but are not limited

to: the Company’s ability to raise sufficient capital on acceptable terms for the restart and develop the Bunker Hill

Mine or to fund ongoing operations; capital market conditions, restriction on labor and international travel and

supply chains; failure to identify mineral resources; failure to convert estimated mineral resources to reserves; the

inability to complete a feasibility study which recommends a production decision; the preliminary nature of

metallurgical test results; the risks of not basing a prod uction decision on a feasibility study of mineral reserves

demonstrating economic and technical viability, resulting in increased uncertainty due to multiple technical and

economic risks of failure which are associated with this production decision includi ng, among others, areas that

are analyzed in more detail in a feasibility study, such as applying economic analysis to resources and reserves,

more detailed metallurgy and a number of specialized studies in areas such as mining and recovery methods,

market analysis, and environmental and community impacts and, as a result, there may be an increased

uncertainty of achieving any particular level of recovery of minerals or the cost of such recovery, including

increased risks associated with developing a commer cially mineable deposit with no guarantee that production

will begin as anticipated or at all or that anticipated production costs will be achieved; failure to commence

production would have a material adverse impact on the Company's ability to generate revenue and cash flow to

fund operations; failure to achieve the anticipated production costs would have a material adverse impact on the

Company's cash flow and future profitability; delays in obtaining or failures to obtain required governmental,

environmental or other project approvals; political risks; changes in equity markets; uncertainties relating to the

availability and costs of financing needed in the future; the inability of the Company to budget and manage its

liquidity in light of the failure to obtain additional financing, including the ability of the Company to complete the

payments pursuant to the terms of the agreement to acquire the Bunker Hill Mine Complex; inflation; changes in

exchange rates; fluctuations in commodity prices; delays in the development of projects; capital, operating and

reclamation costs varying significantly from estimates and the other risks involved in the mineral exploration and

development industry; and those risks set out in the Company’s public documents filed on SED AR+. Although the

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 t hat 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 min eral 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 compa rable with information made public by

companies that report in accordance with U.S. standards.
