BUNKER HILL ANNOUNCES CLOSING AND UPSIZING OF CONVERTIBLE

DEBENTURE FINANCING TO $6 MILLION

TORONTO, January 31, 2022 – Bunker Hill Mining Corp. (the “Company”) (CSE: BNKR, OTCQB: BHLL) is pleased to

announce the closing of the previously announced Convertible Debenture with Sprott Private Resource

Streaming & Royalty Corp (“SRSR” or “Sprott”) for total gross proceeds of $6 million, an increase of $1 million

from the previously envisaged $5 million. All figures are in US dollars unless otherwise stated.

Sam Ash, CEO, stated “We are pleased to announce the closing and upsizing of the second tranche of our project

finance package with Sprott to $6 million. This funds near-term working capital requirements, mine development,

and the advancement of our Prefeasibility Study, including engineering studies for the demobilization and

construction of the Pend Oreille process plant at Bunker Hill. We look forward to updating investors on the

continued execution of our restart plans over the coming weeks.”

Following the satisfaction of all closing conditions, including completion of definitive documentation and a full

security package, the transaction closed on January 28, 202 2. The parties agreed to increase the funding by $1

million, reflecting increased demand from Sprott and other investors. The terms of the Convertible Debenture

are unchanged from the Company’s news release of December 20, 2021, including an annual interest rate of 7.5%

payable in cash or shares at the Company’s option, and a maturity of July 7, 2023. Until the closing of the Stream

of up to $37 million, the final tranche in the project finance package, the Convertible Debenture is convertible into

shares of the Company at a share price of CAD 0.30 per share. At the time that the Stream is advanced, the

investors may elect to retire the Convertible Debenture in shares or with the cash proceeds of the Stream.

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 Securities Act of 1933, as

amended, and Section 21E of the 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. 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”. Since forward -looking statements are based on assumptions and

address future events and conditions, by their very nature they involve inherent risks and uncertainties. A lthough

these statements are based on information currently available to the Company, the Company provides no

assurance 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 information.

Forward looking information in this news release includes, but is not limited to, the Company’s intentions regarding

its objectives, goals or future plans and statements. Factors that could cause actual results to differ materially from

such forward-looking information include, but are not limited to: 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, restriction on labour 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 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, in cluding 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 mate rial 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 obtai ning 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 exch ange 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 r isks set out in the Company’s public documents

filed on SEDAR. Although the Company believes that the assumptions and factors used in preparing the forward -

looking information in this news release are reasonable, undue reliance should not be placed on such 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. 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.

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

Resources

This press release has been prepared in accordance with the requirements of the securities laws in effect in Canada,

which differ from the requir ements of U.S. securities laws. Unless otherwise indicated, all resource and reserve

estimates included in this press release have been disclosed in accordance with NI 43 -101 and the Canadian

Institute of Mining, Metallurgy, and Petroleum 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. Canadian disclosure

standards, including NI 43 -101, differ significantly from the requirements of the United States Securities and

Exchange Commission (“SEC”), and resource and reserve information contained in this press release may not be

comparable to similar information disclosed by U.S. companies. In particular, and without limiting the generality

of the foregoing, the term “resource” does not equate to the term “reserves”. Under U.S. standards, mineralization

may not be classified as a “reserve” unle ss the determination has been made that the mineralization could be

economically and legally produced or extracted at the time the reserve determination is made. The SEC’s disclosure

standards normally do not permit the inclusion of information concerning “measured mineral resources”,

“indicated mineral resources” or “inferred mineral resources” or other descriptions of the amount of mineralization

in mineral deposits that do not constitute “reserves” by U.S. standards in documents filed with the SEC. Inves tors

are cautioned not to assume that any part or all of mineral deposits in these categories will ever be converted into

reserves. U.S. investors should also understand that “inferred mineral resources” have a great amount of

uncertainty as to their exist ence and great uncertainty as to their economic and legal feasibility. It cannot be

assumed that all or any part of an “inferred mineral resource” will ever be upgraded to a higher category. 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. The requirements

of NI 43-101 for disclosure of “reserves” are also not the same as those of the SEC, and reserves disclosed by the

Company in acco rdance with NI 43 -101 may not qualify as “reserves” under SEC standards. Accordingly,

information concerning mineral deposits contained in our website may not be comparable with information made

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