Cautionary
Statements
Neither
the TSXV nor its Regulation Services Provider (as that term is defined in the policies of the TSXV) accepts responsibility for the adequacy
or accuracy of this news release.
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 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.
Forward-looking
statements in this news release include, but are not limited to, statements regarding the Reverse Stock Split, including the Consolidation
Date; completion of the LIFE Offering; the receipt of the approval of the TSXV; the Company’s ability to secure sufficient project
financing to complete the construction of the Bunker Hill Mine and move it to commercial production in a manner that maximizes shareholder
value.
Forward-looking
statements reflect material expectations and assumptions, including, without limitation, expectations and assumptions relating to: Bunker
Hill’s ability to receive sufficient project financing for the construction of the Bunker Hill Mine on an acceptable timeline,
on acceptable terms, or at all; our ability to service our existing debt and meet the payment obligations thereunder; further drilling
and geotechnical work supporting the planned restart and operations at the Bunker Hill Mine; the future price of metals; and the stability
of the financial and capital markets. Factors that could cause actual results to differ materially from such forward-looking statements
include, but are not limited to, those risks and uncertainties identified in public filings made by Bunker Hill with the U.S. Securities
and Exchange Commission (the “SEC”) and with applicable Canadian securities regulatory authorities, and the following: Bunker
Hill’s ability to use the net proceeds of the LIFE Offering in a manner that will increase the value of stockholders’ investments;
the dilution of current stockholders as a result of the consummation of the LIFE Offering; the Company’s ability to obtain all
necessary regulatory and stock exchange approvals with respect to the LIFE Offering and the Reverse Stock Split, including the approval
of the TSXV; Bunker Hill’s ability to operate as a going concern and its history of losses; Bunker Hill’s inability to raise
additional capital for project activities, including through equity financings, concentrate offtake financings or otherwise; the fluctuating
price of commodities; capital market conditions; restrictions on labor and its effects on international travel and supply chains; failure
to identify mineral resources; further geotechnical work not supporting the continued development of the Bunker Hill Mine or the results
described herein; failure to convert estimated mineral resources to reserves; the preliminary nature of metallurgical test results; the
Company’s ability to raise sufficient project financing, on acceptable terms or at all, 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; the Company requiring additional capital expenditures than anticipated, resulting in delays in the expected restart timeline;
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; and capital, operating and reclamation costs
varying significantly from estimates and the other risks involved in the mineral exploration and development industry. 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, or whether and when the Company will
achieve its operational and construction targets. 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.
Readers
are cautioned that the foregoing risks and uncertainties are not exhaustive. Additional information on these and other risk factors that
could affect the Company’s operations or financial results are included in the Company’s annual report and may be accessed
