Bunker Hill Affirms Total Restart Project Budget, and Receives Upsized $20

Million Offtake Finance Proposal

TORONTO, March 10, 2023 -- Bunker Hill Mining Corp. (the “Company”) (CSE: BNKR, OTCQB: BHLL) is pleased to affirm its

total capital cost and budget estimates for the restart of the Bunker Hill Mine and provide an update regarding its project

finance initiatives.

Sam Ash, CEO, stated: “Based on further optimization of our restart plan, we are pleased to report that the total project

budget remains in line with prior estimates. I can also report that our finance plan, centered on the release of $37 million of

stream finance from Sprott Private Resource Streaming & Royalty Corp. (“Sprott”), has now been complemented by

expressions of interest for an upsized offer of $20 million from potential providers of offtake finance.”

TOTAL PROJECT CAPITAL BUDGET AFFIRMED

The project team remains on site at short notice awaiting the conclusion of the on-going equity financing activity and the

finalization of the offtake finance negotiations. Completion of detailed engineering and the commencement of process plant

construction activities are to recommence in Q2 2023.

Working in partnership with its key contractors to adjust certain of its payment schedules the Company has maintained the

integrity of its total pre-production budget. This includes all site and corporate costs and other working capital requirements;

and aims to ensure first concentrate production in Q2 2024.

PROJECT FINANCE PLAN ENHANCED BY UPSIZED OFFTAKE FINANCE PROPOSAL

Based on recent indications of interest, the Company anticipates the ability to increase the targeted amount of offtake finance

to up to $20 million (increased from $15 million previously). This $5 million upsize de-risks the project finance plan by

backstopping ongoing equity financing activities.

The Company expects to select its final offtake partner by Q2 2023 as part of securing access to the $37 million of stream

finance and thereafter begin the execution of its final project plan.

Cautionary Statements

Certain statements in this news release are forward-looking and involve a number of risks and uncertainties. Such forward-

looking statements are within the meaning of that term in Section 27A of the U.S. Securities Act of 1933, as amended, and

Section 21E of the U.S. Securities Exchange Act of 1934, as amended, as well as within the meaning of the phrase ‘forward-

looking information’ in the Canadian Securities Administrators’ National Instrument 51-102 – Continuous Disclosure

Obligations (collectively, “forward-looking statements”). 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”,

“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 forward-looking

statements are based on information currently available to the Company, the Company provides no assurances that actual

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

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 include, but are not limited to: the Company’s intentions regarding its

objectives, goals or future plans and statements; the Company anticipating an upsized amount of

offtake finance based on expressions of interest; the Company expecting to select a final offtake partner over the

coming weeks; the projected total project budget for the restart of the Bunker Hill Mine; the anticipated timing for the

completion of detailed engineering, commencement of process plant construction activities and first concentrate production;

the Company’s ability to raise capital through its project finance initiatives including the equity financing, concentrate offtake

financing of up to $20-million and satisfaction of the conditions for the $37-million stream from Sprott; the Company’s ability to

continue operations;

Factors that could cause actual results to differ materially from such forward-looking statements include, but are not limited

to: the Company’s inability to raise capital, including through equity or concentrate offtake financing or otherwise; the ability to

predict and counteract the effects of COVID-19 on the business of the Company, including but not limited to the effects of

COVID-19 on the price of commodities; capital market conditions; restrictions on labor and its effects on international travel

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

preliminary nature of metallurgical test results; the Company’s ability to restart and develop the Bunker Hill Mine and the risks

of not basing a production 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 including, 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 commercially 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 SEDAR and in the Company’s filings with the U.S.

Securities and Exchange Commission. Although the Company believes that the assumptions and factors used in preparing

the forward-looking statements in this news release are reasonable, undue reliance should not be placed on such statements

or information, which only applies as of the date of this news release, and no assurance can be given that such events will

occur in the disclosed time frames or at all, including as to whether or when the Company will achieve its project finance

initiatives, or as to the actual size or terms of those financing initiatives. The Company disclaims any intention or obligation to

update or revise any forward-looking information, whether as a result of new information, future events or otherwise, other than

as required by law. No stock exchange, securities commission or other regulatory authority has approved or disapproved the

information contained herein.
