Item 1.01. Entry
into a Material Definitive Agreement.
Arrangement
Agreement
On
August 20, 2026, Bunker Hill Mining Corp., a Nevada corporation (“Bunker Hill”), entered into an Arrangement Agreement (the
“Arrangement Agreement”) with Silver47 Exploration Corp., a British Columbia corporation (“Silver47”), pursuant
to which, among other things, Bunker Hill will acquire all of the issued and outstanding common shares of Silver47 (the “Arrangement”).
The Arrangement will be implemented by way of a plan of arrangement (the “Plan of Arrangement”) in accordance with the Business
Corporations Act (British Columbia) (the “BCBCA”) and is subject to approval by the Supreme Court of British Columbia (the
“Court”) and the stockholders of Bunker Hill and Silver47. Upon completion of the Arrangement, Silver47 will be a direct
wholly owned subsidiary of Bunker Hill.
On
the terms and subject to the conditions of the Arrangement Agreement and the Plan of Arrangement, at the effective time of the Arrangement
(the “Effective Time”), Silver47 shareholders will receive 0.1724 shares of common stock in Bunker Hill (each whole share,
a “Bunker Hill Share”) in exchange for each Silver47 common share (each, a “Silver47 Share”) held immediately
prior to the closing of the Arrangement (the “Exchange Ratio”). No fractional Bunker Hill Shares will be issued in the Arrangement,
and where the aggregate number of Bunker Hill Shares to be issued to a person as consideration under or as a result of the Arrangement
would result in a fraction, the number of Bunker Hill Shares to be received by that securityholder will be rounded down to the nearest
whole Bunker Hill Share, and no person will be entitled to any compensation in respect of a fractional Bunker Hill Share.
At
the Effective Time, on the terms and subject to the conditions of the Arrangement Agreement, each Silver47 option (a “Silver47
Option”) outstanding immediately prior to the Effective Time, whether vested or unvested, will be exchanged for an option (each,
a “Replacement Option”) to acquire Bunker Hill Shares equal to (rounded down to the nearest whole number) the number of Silver47
Shares subject to such Silver47 Option immediately prior to the Effective Time multiplied by the Exchange Ratio. The exercise price per
Bunker Hill Share subject to a Replacement Option will equal the exercise price per Silver47 Share subject to the corresponding Silver47
option immediately before the Effective Time divided by the Exchange Ratio, with the aggregate exercise price payable on any particular
exercise rounded up to the nearest whole cent. The Replacement Options shall be exercisable until the original expiry date of the Silver47
Option, except that the term of any Replacement Options, including any outstanding Replacement Options held by or on behalf of an individual
that will not be continuing as a director, officer, employee or consultant of Bunker Hill or any of its affiliates (including Silver47)
following 60 days after the effective date of the Arrangement, shall be the lesser of (i) the current expiry date of the Silver47 Option,
and (ii) the date that is 120 days following the effective date of the Arrangement.
Pursuant
to the Plan of Arrangement, each Silver47 restricted share unit (a “Silver47 RSU”) outstanding immediately prior to the Effective
Time, whether vested or unvested, will be deemed to be immediately and unconditionally vested and will be settled by Silver47 at the
Effective Time, net of applicable withholdings, in exchange for Silver47 Shares, which will be transferred to Bunker Hill under the Plan
of Arrangement, after which the holders will be treated as Silver47 shareholders for purposes of the Arrangement.
Pursuant
to the Plan of Arrangement, each Silver47 warrant outstanding immediately prior to the Effective Time, whether vested or unvested, will
be exchanged for a warrant (each, a “Replacement Warrant”) to acquire from Bunker Hill a number of Bunker Hill Shares equal
to the number of Silver47 Shares subject to the warrant immediately prior to the Effective Time multiplied by the Exchange Ratio, rounded
down to the nearest whole Bunker Hill Share. The exercise price per Bunker Hill Share subject to a Replacement Warrant will equal the
exercise price per Silver47 Share subject to the corresponding Silver47 warrant immediately before the Effective Time divided by the
Exchange Ratio, with the aggregate exercise price payable on any particular exercise rounded up to the nearest whole cent. Replacement
Warrants will otherwise have the same terms, including expiry, as the corresponding Silver47 warrants, but will be exercisable exclusively
on a cashless basis if the applicable U.S. registration statement is not effective or usable or the holder has not established that a
cash exercise is permissible under applicable U.S. securities laws without resale restrictions.
Pursuant
to the Arrangement Agreement, at the Effective Time, the board of directors of Bunker Hill (the “Bunker Hill Board”) will
be fixed at seven directors: Richard Williams (Executive Chairman), Mark Cruise (Lead Independent Director), Pamela Saxton, Kelli Kast,
Samuel Ash, Gary Thompson and Galen McNamara. The Arrangement Agreement also requires Bunker Hill to appoint Galen McNamara as President
and Chief Investment Officer.
Each
of Bunker Hill and Silver47 has made customary representations and warranties and covenants in the Arrangement Agreement, including covenants
regarding the conduct of their respective businesses prior to the closing of the Arrangement.
Silver47
shareholders will be asked to vote on the Arrangement (the “Arrangement Resolution”) at a special meeting, and the Bunker
Hill shareholders will be asked to vote on (a) the Bunker Hill Share Issuance Resolution, approving the issuance of Bunker Hill Shares
in connection with the Arrangement, and (b) the Bunker Hill Charter Amendment Resolution, approving an amendment to Bunker Hill’s
articles of incorporation to increase authorized Bunker Hill Shares from 100,000,000 to 400,000,000 (together, the “Bunker Hill
Resolutions”), at a special meeting. Bunker Hill and Silver47 will use commercially reasonable efforts to schedule the meetings
on the same date. Each meeting is to be held by November 15, 2026; however, if Bunker Hill files or is required to file a Schedule 14A
proxy statement with the SEC, the meetings will be held as promptly as reasonably practicable following SEC clearance of the Bunker Hill
Proxy Statement. The Arrangement is conditioned on the approval of the Arrangement Resolution by (a) at least 66⅔% of the votes
cast by Silver47 shareholders present in person or by proxy at the Silver47 meeting, and (b) a simple majority of the votes cast by Silver47
shareholders present in person or by proxy at the Silver47 meeting, excluding votes required to be excluded under MI 61-101 (together,
the “Silver47 Shareholder Approval”). The Bunker Hill Share Issuance Resolution requires a simple majority of votes cast
by Bunker Hill shareholders present in person or by proxy, and the Bunker Hill Charter Amendment Resolution requires a simple majority
of the votes entitled to be cast by Bunker Hill shareholders (collectively, the “Bunker Hill Shareholder Approval”). Consummation
of the Arrangement is also subject to (a) the absence of any law, injunction or other governmental order that prohibits consummation
of the Arrangement, (b) approval of the Arrangement by the Court, (c) receipt of TSXV approval of the Arrangement and approval of the
listing and posting for trading on the TSX and any other stock exchange on which Bunker Hill Shares are then listed, subject to standard
listing conditions, of the Bunker Hill Shares issuable pursuant to the Arrangement, including the Bunker Hill Shares underlying the Replacement
Options and Replacement Warrants, (d) receipt of required regulatory approvals, (e) exemption of the Consideration Shares and Replacement
Convertible Securities from registration requirements under Section 3(a)(10) of the U.S. Securities Act, (f) absence of a Material Adverse
Effect (as defined in the Arrangement Agreement) on either Silver47 or Bunker Hill, (g) holders of no more than 5% of the Silver47 Shares
having exercised Silver47 Dissent Rights and (h) other customary closing conditions, including the accuracy of the other party’s
representations and warranties, subject to applicable materiality qualifications, and compliance with covenants and agreements in the
Arrangement Agreement.
Each
of Bunker Hill and Silver47 is subject to customary restrictions on soliciting alternative acquisition proposals and on providing information
to, or engaging in discussions with, third parties regarding such proposals, subject to limited exceptions before the applicable shareholder
approval for an unsolicited acquisition proposal that the board of directors, as applicable, has determined in good faith constitutes
or would reasonably be expected to constitute a Superior Proposal (as defined in the Arrangement Agreement). Before obtaining the Bunker
Hill Shareholder Approval, the Bunker Hill Board may, upon receipt of an Acquisition Proposal (as defined in the Arrangement Agreement)
with respect to Bunker Hill that did not result from a material breach of the solicitation restrictions, and that it determines in good
faith constitutes a Superior Proposal, change its recommendation that the Bunker Hill shareholders approve the Bunker Hill Resolutions.
Before obtaining the Silver47 Shareholder Approval, the board of directors of Silver47 (the “Silver47 Board”) may, upon receipt
of an Acquisition Proposal in respect to Silver47 that did not result from a material breach of the solicitation restrictions, and that
it determines in good faith constitutes a Superior Proposal, change its recommendation that Silver47 shareholders approve the Arrangement
Resolution. Before either Board changes its recommendation, the other Party must be provided with a five business day “match right.”
The
Arrangement Agreement contains certain termination rights for both Silver47 and Bunker Hill, including where (a) the Arrangement is not
consummated on or before January 31, 2027, or such later date as may be agreed to in writing by the parties (the “Outside Date”),
(b) a law or order comes into effect prohibiting consummation of the Arrangement and such law or order has become final and non-appealable
or (c) the Silver47 Shareholder Approval or the Bunker Hill Shareholder Approval is not obtained at the relevant meeting held for such
purpose. Additionally, each of Bunker Hill and Silver47 has a separate termination right if (a) the board of directors of the other party
changes its recommendation under certain circumstances, (b) the other party materially breaches its non-solicitation restrictions, (c)
there has been a Material Adverse Effect on the other party that is incapable of being cured prior to the Outside Date, (d) the other
party breaches its representations, warranties or covenants in a manner that causes a closing condition to be incapable of being satisfied
by the Outside Date or (e) such party authorizes the entry into an agreement with respect to a Superior Proposal, subject to compliance
with the procedures set forth in the Arrangement Agreement and payment of the applicable termination fee.
The
Arrangement Agreement further provides that, upon termination of the Arrangement Agreement under certain circumstances, Silver47 or Bunker
Hill, as the case may be, will be required to pay a termination fee to the other party (each a “Termination Fee”). Silver47
is required to pay a Termination Fee of approximately US$5,700,000 (C$7,900,000) in the following circumstances: (a) Bunker Hill
terminates the Arrangement Agreement because of a change of recommendation by the Silver47 Board or a material breach by Silver47 of
its non-solicitation restrictions; (b) Silver47 terminates the Arrangement Agreement to enter into an agreement with respect to a Superior
Proposal; (c) either party terminates the Arrangement Agreement because the Arrangement is not completed by the Outside Date or because
of a failure to obtain the Silver47 Shareholder Approval, at a time when Bunker Hill is entitled to terminate the Arrangement Agreement
because of a change of recommendation by the Silver47 Board; or (d) either party terminates the Arrangement Agreement because of a failure
to obtain the Silver47 Shareholder Approval or Bunker Hill terminates the Arrangement Agreement because Silver47 has wilfully or intentionally
breached its representations, warranties or covenants, but only if, in each case, (i) prior to such termination an acquisition proposal
for Silver47 has been made or publicly announced (and is not withdrawn at least five business days before the Silver47 shareholder meeting)
and (ii) within 12 months following the date of termination Silver47 consummates any acquisition proposal for Silver47 or enters into
an agreement for any acquisition proposal for Silver47, which is subsequently completed. Bunker Hill is required to pay a Termination
Fee of approximately US$6,600,000 (C$9,100,000) in the following circumstances: (a) Silver47 terminates the Arrangement Agreement because
of a change of recommendation by the Bunker Hill Board or a material breach by Bunker Hill of its non-solicitation restrictions; (b)
Bunker Hill terminates the Arrangement Agreement to enter into an agreement with respect to a Superior Proposal; (c) either party terminates
the Arrangement Agreement because the Arrangement is not completed by the Outside Date or because of a failure to obtain the Bunker Hill
Shareholder Approval, at a time when Silver47 is entitled to terminate the Arrangement Agreement because of a change of recommendation
by the Bunker Hill Board; or (d) either party terminates the Arrangement Agreement because of a failure to obtain the Bunker Hill Shareholder
Approval, or Silver47 terminates the Arrangement Agreement because Bunker Hill has wilfully or intentionally breached its representations,
warranties or covenants, but only if, in each case, (i) prior to such termination an acquisition proposal for Bunker Hill has been made
or publicly announced (and is not withdrawn at least five business days before the Bunker Hill stockholder meeting) and (ii) within 12
months following the date of termination Bunker Hill consummates such acquisition proposal or enters into an agreement with respect to
an acquisition proposal that is subsequently completed.

Arrangement Agreement, a copy of which is filed as Exhibit 2.1 hereto and is incorporated herein by reference. The Arrangement Agreement
has been included as an exhibit hereto solely to provide investors and securityholders with information regarding its terms. It is not
intended to be a source of financial, business or operational information about Bunker Hill, Silver47 or their respective subsidiaries

agreement and as of specific dates, were solely for the benefit of the parties to the Arrangement Agreement, may be subject to limitations
agreed upon by the parties, including being qualified by confidential disclosures made for the purposes of allocating contractual risk

applicable to the parties that differ from those applicable to investors. Investors and securityholders should not rely on the representations,
warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of Bunker Hill or
Silver47 or any of their subsidiaries or affiliates. Moreover, information concerning the subject matter of the representations and warranties
may change after the date of the Arrangement Agreement, which subsequent information may or may not be fully reflected in Bunker Hill’s

files or has filed with the SEC.
Silver47
Voting Agreements
On
August 20, 2026, as an inducement for Bunker Hill to enter into the Arrangement Agreement, Bunker Hill entered into support and voting
agreements (the “Silver47 Voting Agreements”) with directors and certain members of the executive leadership team of Silver47

and not in their capacities as directors or officers of Silver47 have agreed, among other things (a) to vote or cause to be voted all
Silver47 Shares and any other securities of Silver47 owned or acquired by them during the term of the Silver47 Voting Agreements (the
“Silver47 Holder Securities”) in favor of the Arrangement and against any resolution that could reasonably be expected to
adversely affect the likelihood of completion of the Arrangement, and (b) not to sell, transfer, pledge or assign any Silver47 Holder
Securities, with certain exceptions.
The
Silver47 Voting Agreements may be terminated (a) at any time upon the written agreement of Bunker Hill and the applicable Silver47 Holder;
(b) by the applicable Silver47 Holder if any representation or warranty of Bunker Hill in the applicable Silver47 Voting Agreement is
not true and correct in all material respects or the Exchange Ratio as in effect on the date of the applicable Silver47 Voting Agreement
is modified in any manner adverse to the applicable Silver47 Holder; or (c) by Bunker Hill if any representation or warranty of the applicable
Silver47 Holder in the applicable Silver47 Voting Agreement is not true and correct in all material respects or the applicable Silver47
Holder has not complied with its covenants and the failure has not been cured within ten business days after written notice. Each Silver47
Voting Agreement automatically terminates at the earliest of (a) the Effective Time and (b) the termination of the Arrangement Agreement
in accordance with its terms.
The
foregoing summary of the Silver47 Voting Agreement does not purport to be complete and is qualified in its entirety by reference to the
Form of Silver47 Voting Agreement, a copy of which is filed as Exhibit 10.1 hereto and is incorporated herein by reference.
Bunker
Hill Voting Agreements
On
August 20, 2026, as an inducement for Silver47 to enter into the Arrangement Agreement, Silver47 entered into support and voting agreements
(the “Bunker Hill Voting Agreements”) with directors, certain members of the executive leadership team of Bunker Hill and
certain significant shareholders of Bunker Hill (each, a “Bunker Hill Holder”), whereby, among other things, such Bunker
Hill Holders, in their capacities as security holders and not in their capacities as directors or officers of Bunker Hill have agreed,
among other things, (a) to vote or cause to be voted all Bunker Hill Shares and any other securities of Bunker Hill owned or acquired
by them during the term of the Bunker Hill Voting Agreements (the “Bunker Hill Holder Securities”) in favor of the Arrangement
and against any resolution that could reasonably be expected to adversely affect the likelihood of completion of the Arrangement, and
(b) not to sell, transfer, pledge or assign any Bunker Hill Holder Securities, with certain exceptions.
The
Bunker Hill Voting Agreements may be terminated (a) at any time upon the written agreement of Silver47 and the applicable Bunker Hill
Holder; (b) by the applicable Bunker Hill Holder if (i) any representation or warranty of Silver47 in the applicable Bunker Hill Voting
Agreement is not true and correct in all material respects, (ii) the Exchange Ratio as in effect on the date of the applicable Bunker
Hill Voting Agreement is modified in any manner adverse to the applicable Bunker Hill Holder or (iii) there is any material amendment

Bunker Hill Voting Agreements automatically terminate at the earliest of (a) the Effective Time, or (b) the termination of the Arrangement
Agreement in accordance with its terms, with the exception of the Bunker Hill Voting Agreements entered into with Teck Resources Limited
and Sprott Streaming and Royalty Corp, which automatically terminate at the earliest of (a) the Effective Time, (b) the Bunker Hill Meeting
does not convene by November 15, 2026, (c) the Effective Time has not occurred prior to January 31, 2027, or (d) the termination of the
Arrangement Agreement in accordance with its terms.
The
foregoing summary of the Bunker Hill Voting Agreements does not purport to be complete and is qualified in its entirety by reference
to the Form of Bunker Hill Voting Agreement, a copy of which is filed as Exhibit 10.2 hereto and is incorporated herein by reference.
Item
3.02. Unregistered Sales of Equity Securities.
The
information set forth under Item 1.01 of this Current Report on Form 8-K is hereby incorporated into this Item 3.02.
As
described in Item 1.01 of this Current Report on Form 8-K, Bunker Hill has agreed in the Arrangement Agreement that, if the Plan of Arrangement
becomes effective and its acquisition of the issued and outstanding common shares of Silver47 is thereby completed, Bunker Hill will
issue 0.1724 of a share of Bunker Hill Common Stock for each issued and outstanding Silver47 common share, or approximately 36 million
shares of Bunker Hill Common Stock in the aggregate (based on the currently issued and outstanding Silver47 common shares). If issued,
and after the consummation of the Arrangement, such shares will represent approximately 43% of the total number of outstanding shares
of Bunker Hill Common Stock.
Section
3(a)(10) of the Securities Act exempts from the registration requirements under the Securities Act the issuance of securities which have
been approved, after a hearing upon the substantive and procedural fairness of the terms and conditions of the relevant transaction,
at which all persons to whom it is proposed the securities will be issued shall have the right to appear, by any court expressly authorized
by law to grant such approval. Under the Arrangement Agreement, Silver47 will submit the Plan of Arrangement to the Court for an interim
order permitting notice to all persons to which the Consideration Shares and the Replacement Convertible Securities will be issuable.
Following Silver47’s receipt of the Silver47 Shareholder Approval and a hearing at which such persons will have the right to appear,
Silver47 will seek a final order from the Court as to the substantive and procedural fairness of the Plan of Arrangement. Such final
order is a condition to the consummation of the Plan of Arrangement and the issuance of the Consideration Shares and the Replacement
Convertible Securities. Bunker Hill therefore anticipates that, if the Plan of Arrangement becomes effective under the terms and conditions
described in the Arrangement (including the receipt of such final order from the Court), the issuance of the Consideration Shares and
the Replacement Convertible Securities to the Silver47 securityholders will be exempt from the registration requirements under the Securities
Act pursuant to Section 3(a)(10) thereof.
Item
7.01. Regulation FD Disclosure.
On
August 21, 2026, Bunker Hill and Silver47 issued a joint press release that includes, among other matters, information related to the
Arrangement. A copy of the press release is filed as Exhibit 99.1 and is incorporated into this Item 7.01 by reference.
In
connection with the announcement of the Agreement, Bunker Hill intends to provide supplemental information regarding the proposed transaction
in presentations to analysts and investors. The slides that will be available in connection with those presentations are attached as
Exhibit 99.2 hereto and are incorporated into this Item 7.01 by reference.
The
information provided under Item 7.01 of this Current Report on Form 8-K, including Exhibit 99.1 and Exhibit 99.2 hereto, is being furnished
and is not deemed to be “filed” with the SEC for the purposes of Section 18 of the Exchange Act or otherwise subject to the
liabilities of that section and is not incorporated by reference into any filing of Bunker Hill under the Securities Act or the Exchange
Act, whether made before or after the date hereof, except as shall be expressly set forth by specific reference to this Current Report
on Form 8-K in such a filing.

Cautionary
Statement Regarding Forward-Looking Statements
This
communication contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended
(the “Securities Act”) and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”),
which are intended to be covered by the safe harbor created by such sections and other applicable laws and “forward-looking information”
within the meaning of applicable Canadian securities laws. Where a forward-looking statement expresses or implies an expectation or belief
as to future events or results, such expectation or belief is expressed in good faith and believed to have a reasonable basis. However,
such statements are subject to risks, uncertainties and other factors, which could cause actual results to differ materially from future
results expressed, projected or implied by the forward-looking statements. Forward-looking statements often address our expected future
business and financial performance and financial condition, and often contain words such as “anticipate,” “intend,”
“plan,” “will,” “would,” “estimate,” “expect,” “believe,” “target,”
“indicative,” “preliminary,” or “potential.” Forward-looking statements in this communication may
include, without limitation: (i) statements relating to Bunker Hill’s planned acquisition of Silver47 and the expected terms, timing
and closing of the proposed transaction, including receipt of required approvals and satisfaction of other customary closing conditions;
(ii) estimates of future production, including expected annual production range; (iii) estimates of planned expenses and capital expenditures,
including the expected costs of construction, commissioning, and operation and the sources of funds to pay for such costs; (iv) estimates
of future capital expenditures; (v) estimates of future cost reductions, synergies, including pre-tax synergies, savings and efficiencies;
(vi) expectations regarding future exploration and the development, growth and potential of Bunker Hill’s and Silver47’s
operations, project pipeline and investments; (vii) expectations of future dividends and returns to shareholders; (viii) expectations
of future balance sheet strength and credit ratings; (ix) expectations of future equity and enterprise value; (x) expected listing of
common stock on the TSX or any other stock exchange; and (xi) expectations of future plans and benefits. Estimates or expectations of
future events or results are based upon certain assumptions, which may prove to be incorrect. Such assumptions, include, but are not
limited to: (i) there being no significant change to current geotechnical, metallurgical, hydrological and other physical conditions;
(ii) permitting, development, operations and expansion of Bunker Hill’s and Silver47’s operations and projects being consistent
with current expectations and mine plans; (iii) political developments in any jurisdiction in which Bunker Hill or Silver47 operates
being consistent with its current expectations; (iv) certain exchange rate assumptions for the Canadian dollar to the U.S. dollar; (v)
certain price assumptions, including the price of silver; (vi) prices for key supplies being approximately consistent with current levels;
(vii) the accuracy of current mineral reserve, mineral resource and mineralized material estimates; and (viii) other planning assumptions.
Factors
that could cause actual results to differ, and differ materially, include, but are not limited to: Bunker Hill’s ability to consummate
the proposed transaction; the occurrence of any event, change or other circumstance that could give rise to the termination of the Arrangement
Agreement; failure to obtain applicable regulatory or shareholder approvals in a timely manner or at all; failure to satisfy any other
conditions to closing of the proposed transaction; failure to realize the anticipated benefits and synergies of the proposed transaction
in the expected timeframe or at all, including as a result of a delay in consummating the proposed transaction; the success of integration
plans and the time required to successfully integrate Silver47’s operations with those of Bunker Hill; the focus of management’s
time and attention on the proposed transaction and other potential disruptions arising from the proposed transaction; the effects of
the announcement of the proposed transaction on Bunker Hill’s or Silver47’s businesses; Bunker Hill’s or Silver47’s
ability to retain certain key employees following the public announcement of the proposed transaction; the potential for litigation related
to the proposed transaction; Bunker Hill’s or Silver47’s ability to obtain certain third party or governmental regulatory
consents, approvals or clearances; potential undisclosed liabilities of Silver47 not identified during the due diligence process; the
impact of the proposed transaction on the market price of Bunker Hill’s or Silver47’s common stock and/or operating results;
silver and other metals price volatility, currency fluctuations, operational risks, increased production costs and variances in ore grade
or recovery rates from those assumed in mining plans, political risk, community relations, conflict resolution governmental regulation
and judicial outcomes and other risks; and general economic conditions that are less favorable than expected. For more detailed discussion
of such risks and other factors, see Bunker Hill’s 2025 Annual Report on Form 10-K, filed with the Securities and Exchange Commission
(the “SEC”), as well as Bunker Hill’s other SEC filings, available on the SEC website and www.bunkerhillmining.com/investors,
Silver47’s most recent annual information form as well as Silver47’s other filings made with Canadian securities regulatory
authorities and available on SEDAR+ and www.silver-47.com/investors. Bunker Hill is not affirming or adopting any statements or reports
attributed to Silver47 (including prior mineral reserve and resource declaration) in this communication or made by Silver47 outside of
this communication. Silver47 is not affirming or adopting any statements or reports attributed to Bunker Hill (including prior mineral
reserve and resource declaration) in this communication or made by Bunker Hill outside of this communication. Bunker Hill and Silver47
do not undertake any obligation to release publicly revisions to any “forward-looking statement,” including, without limitation,
outlook, to reflect events or circumstances after the date of this communication, or to reflect the occurrence of unanticipated events,
except as may be required under applicable securities laws. Investors should not assume that any lack of update to a previously issued
“forward-looking statement” constitutes a reaffirmation of that statement. Continued reliance on “forward-looking statements”
is at investors’ own risk.
Cautionary
Note to U.S. Investors
Silver47
discloses estimates of “measured,” “indicated,” and “inferred” mineral resources as such terms are
used in Canada’s National Instrument 43-101 Standards of Disclosure for Mineral Projects (“NI 43-101”), whereas Bunker
Hill’s public disclosures are governed by the Exchange Act, including Regulation S-K 1300 thereunder (“S-K 1300”),
in addition to NI 43-101. Although S-K 1300 and NI 43-101 have similar goals in terms of conveying an appropriate level of confidence
in the disclosures being reported, they at times embody different approaches or definitions. Consequently, investors are cautioned that
public disclosures by Silver47 prepared in accordance with NI 43-101 may not be comparable to similar information made public by companies,
including Bunker Hill, subject to S-K 1300 and the other reporting and disclosure requirements under the U.S. federal securities laws
and the rules and regulations thereunder.

BUNKER
HILL AND SILVER47 ANNOUNCE MERGER TO CREATE A ‘MADE IN AMERICA’ U.S. SILVER & CRITICAL MINERALS CHAMPION
KELLOGG,
IDAHO | VANCOUVER, BRITISH COLUMBIA, August 21, 2026 — Bunker Hill Mining Corp. (“Bunker Hill”) (TSX: BNKR | OTCQB:
BHLL), and Silver47 Exploration Corp. (“Silver47”) (TSXV: AGA | OTCQX: AAGAF | Frankfurt: QP2) are pleased to announce
that they have entered into a definitive arrangement agreement dated August 20, 2026 (the “Arrangement Agreement”)
pursuant to which Bunker Hill has agreed to acquire all of the issued and outstanding common shares of Silver47 by way of a plan of arrangement
(the “Transaction”). Concurrent with the Transaction, the combined company (the “Combined Company”)
will seek a name change to “Bunker Hill Silver Corp.” and remain listed on the Toronto Stock Exchange (“TSX”).
Under
the terms of the Arrangement Agreement, Silver47 shareholders will receive 0.1724 shares of common stock in Bunker Hill (each whole share,
a “Bunker Hill Share”) in exchange for each Silver47 common share (each, a “Silver47 Share”) held
immediately prior to the closing of the Transaction (the “Exchange Ratio”). Upon completion of the Transaction, existing
Bunker Hill shareholders and Silver47 shareholders are expected to own approximately 57% and 43% of the outstanding Bunker Hill Shares
on a basic basis, respectively. The Exchange Ratio implies consideration of approximately US$0.67 (C$0.93) per Silver47 Share based on
the last closing price of Bunker Hill on the TSX on August 20, 2026. The consideration represents a premium of approximately 38% to Silver47’s
last closing price on the TSX Venture Exchange (the “TSXV”) on August 20, 2026 and an approximately 30% premium to
the 20-day volume weighted average price (“VWAP”).
Bunker
Hill and Silver47 will host a joint conference call and webcast Friday, August 21, 2026, at 10:00 am Eastern Daylight Time (EDT). Details
provided below.
The
Transaction will combine the operational Bunker Hill Mine located in the Silver Valley of Idaho, with Silver47’s silver-focused
U.S. exploration and development pipeline in Alaska, Nevada and New Mexico. As Bunker Hill ramps up to commercial production, the mine
will act as the operating engine that funds growth and development near the Bunker Hill Mine, and throughout the Combined Company’s
expanded U.S. exploration and development portfolio. Operating cash flow and a strong pro forma cash balance is expected to provide the
necessary capital to complete aggressive exploration and development, and provide working capital for the Bunker Hill Mine.
Bunker
Hill has arranged additional funding from two of its existing partners, entering into a US$10,000,000 concentrate prepayment facility
with Ocean Partners UK Ltd. (“Ocean Partners”) and drawing US$1,000,000 under its standby facility with Teck Resources
Limited (“Teck”).
Transaction
Highlights & Strategic Rationale
| |
● |
Creating
a New U.S. Silver and Critical Minerals Champion: The combination of Bunker Hill’s anticipated cash-flow from the Bunker
Hill Mine with Silver47’s high-quality development pipeline establishes a new ‘Made in America’ U.S. champion in
silver and critical minerals. Bunker Hill is currently listed on the TSX and in the U.S. on the OTCQB and is pursuing a listing on
the NYSE American. There is no guarantee the Bunker Hill Shares will be listed on the NYSE American. |
| |
● |
Enhanced
Scale for a Producer Multiple: With a pro forma basic market capitalization of US$326M, increased trading liquidity, and a strengthened
shareholder base, the Combined Company, with commercial production expected to be achieved at the Bunker Hill Mine and a pipeline
of additional mineral exploration assets, is expected to realize opportunity to attract broader institutional ownership and index
inclusion. |
| |
|
|
| |
● |
Clear
Path to Annual Production of +5 Moz AgEq: Production is expected to ramp from +980 koz AgEq in 2026 to +2,500 koz AgEq in 2027
at the Bunker Hill Mine¹, with the Bunker Hill 2.0 expansion to 2,500 tpd — the largest mill in the Silver Valley —
driving annual production toward +5 Moz AgEq per year. |
| |
|
|
| |
● |
Top-Tier
Portfolio of U.S. Silver Projects with District-Scale Upside: The Transaction brings together four U.S. silver projects with
an aggregate mineral resource inventory of 80 Moz AgEq measured and indicated and 308 Moz AgEq inferred (see mineral resource table
below for resources by project). Three drill programs are currently underway across the portfolio and multiple district-scale systems
provide exploration upside with the potential to expand existing mineral resources through future exploration success. |
| |
|
|
| |
● |
Strengthened
Balance Sheet and Access to Capital: An enhanced treasury and improved access to capital position the Combined Company to support
the ramp-up at the Bunker Hill Mine, and ongoing exploration and development across the portfolio. |
| |
|
|
| |
● |
Proven
Operators and Proven Explorers: Combining Bunker Hill’s mine-building, stakeholder engagement and operating expertise with
Silver47’s exploration and discovery track record, the Combined Company will benefit from deep capital markets experience and
a board with major-producer, M&A, and government relations expertise. |
| |
|
|
| |
● |
U.S.
Government Partner of Choice: The Combined Company is expected to leverage its established relationships with the U.S. EPA, U.S.
EXIM Bank, the U.S. Department of Energy, and the U.S. Office of Strategic Capital to support project financing, permitting, and
development as the United States continues to prioritize domestic mining and critical minerals supply chains. |

Based on analyst consensus projections
Richard
Williams, Executive Chairman of Bunker Hill, commented: “As Bunker Hill advances towards commercial production targeted in
the fourth quarter of 2026, we are very excited to partner with Silver47 to add depth to our leadership team, strengthen the balance
sheet and add silver and critical metals potential to an exclusively U.S.-based project portfolio. This is a ‘Made in America’
transaction at a time when the U.S. domestic mining industry, its investors and the users of U.S. metals need new, ambitious leaders
capable of safely building and operating profitable mines as well as conducting highly prospective exploration and other strategic acquisitions.”
Gary
Thompson, Executive Chairman of Silver47, commented: “The combination of the exploration portfolio and capability of Silver47
with Bunker Hill’s mine building and operational track-record creates a strong foundation for this growth focused company. As the
Bunker Hill Mine targets commercial production, its cash flow will provide the organic power to unlock significant value across the four
U.S. sites, and secure the valuation multiples that come with scale, reliable production, and a safe and mining friendly jurisdiction.”
Sam
Ash, President and CEO of Bunker Hill, commented: “In addition to unlocking the many upsides to our newly operational Bunker
Hill Mine, such as bringing the high-grade Cate-8 discovery into the mine plan, returning the mine to its historic 50/50 silver to base
metals mix and potentially expanding our throughput to 2,500 tpd, we have been actively looking to partner with the right U.S.-focused
silver and critical metals company to accelerate the pace and depth of U.S.-based growth. I know that the Bunker Hill-Silver47 combination
achieves this, and I could not be more excited to partner with Galen McNamara and his team of exploration geologists to help build a
new US mining champion at a critical time for our country”.
Galen
McNamara, CEO & Director of Silver47, commented: “Very few teams in the
U.S. have restarted a mine in a district with as much history and as much scrutiny as the Silver Valley. Sam Ash and the Bunker Hill
team have brought the Bunker Hill Mine back into operation — safely, and with the confidence of their regulators, their community,
and the State of Idaho. That operating credibility is exactly what a high-quality development portfolio like ours needs behind it. We
are also building at the right moment: this Administration has made rebuilding America’s mineral supply chains a national priority,
silver has been added to the U.S. critical minerals list, and federal permitting is moving with a speed our industry has not seen in
decades. Combining our American silver assets with a producing mine and a supportive policy backdrop is how a U.S. champion gets built,
and we look forward to building it together.”

Bunker
Hill Mine and Ranger-Page Project Overview
The
Bunker Hill Mine is a historic mine operation located in Idaho’s Coeur d’Alene Mining District, which was first discovered
in 1885 and operated continuously for nearly a century until its closure in 1981. During its 95 year run, the Bunker Hill Mine yielded
42.8 million tons of ore, at average grades of 8.4% Pb, 4.5% Zn, and 3.5 oz/ton Ag. A restart is currently underway with first production
now achieved and the mine ramping up to commercial production, which is expected to be achieved in Q4 2026. Ongoing projects to optimize
the Bunker Hill Mine include exploration to extend the mine life and increase the silver component of mill feed, and investigation of
a significant mill expansion from 1,800 tpd to 2,500 tpd, under the Bunker Hill 2.0 expansion.
Additional
exploration and mineral resource upside exists at the Bunker Hill Mine’s neighbouring Ranger-Page project. Bunker Hill recently
acquired the neighbouring Ranger-Page project which hosts six historical high-grade silver mines. Recent 2024-2025 high-grade drill intercepts
at the Ranger-Page Project include 10.2 feet (3 m) of 162 g/t Ag, 19.7% Zn, and 19.4% Pb (drill thickness). Three high-priority targets
have been identified at Ranger-Page: the recently discovered vein near the Blackhawk Mine Curlew Vein, down-plunge extensions of the
Ranger-Page Mine Tony Vein, and the Government Gulch Fault corridor between the historical mine workings of the Bunker Hill Mine and
the Ranger-Page Mine. The Government Gulch target has compelling long-term potential as a large unexplored area along strike of structures
controlling mineralization at two of the largest mines in the Silver Valley, which has seen almost no modern exploration due to the historic
competing adjacent land holders.
Hughes
Project Overview
Silver47’s
100%-owned Hughes Project is a district-scale silver project located in central Nevada’s prolific Tonopah Mining District along
the Walker Lane Trend. The project combines significant exploration upside with near-term production potential through the re-treatment
of historic tailings, while active drilling continues to expand the resource base. The Hughes Project hosts indicated in-situ mineral
resources of 0.98 million tonnes grading 333 g/t silver equivalent (AgEq), containing 10.3 million silver equivalent ounces; inferred
in-situ mineral resources of 2.44 million tonnes grading 421 g/t AgEq, containing 32.9 million silver equivalent ounces; and inferred
tailings mineral resources of 1.26 million tonnes grading 68 g/t AgEq, containing 2.74 million silver equivalent ounces, all as reported
in an NI 43-101 Technical Report dated March 3, 2025. Recent drilling has confirmed exceptional high-grade mineralization across 6.2
kilometers of strike, within and along extensions of the historic Tonopah silver district, underscoring the project’s significant
resource expansion potential. Notable results include hole SUM23-59 at the Ruby discovery, which intersected 3.0 meters grading 1,450
g/t silver equivalent (812 g/t silver and 8.4 g/t gold). Strategically positioned near existing infrastructure, the Hughes Project encompasses
a largely underexplored land package where modern exploration is unlocking new high-grade discovery opportunities.
Red
Mountain Project Overview
Silver47’s
100%-owned Red Mountain Project, located approximately 100 km south of Fairbanks, Alaska, is Silver47’s Most advanced silver and
critical minerals asset. Strategically situated within the prolific Bonnifield Mining District, the project hosts an inferred mineral
resource of 15.6 million tonnes grading 336 g/t silver equivalent (AgEq), containing 168.6 million silver equivalent ounces. Recent drilling
has confirmed robust high-grade polymetallic mineralization and highlights the project’s significant resource expansion potential.
Notable results include 22.3 meters grading 601 g/t AgEq (150.6 g/t silver, 0.82 g/t gold, 5.86% zinc, 2.60% lead, and 0.13% copper)
from a depth of 18.9 meters within the Dry Creek Deposit. Beyond its current resource, the Red Mountain Project hosts a highly prospective
60-kilometer mineralized trend containing more than 35 known mineralized prospects. The current mineral resource is derived from just
two of these prospects (Dry Creek and West Tundra Flats), highlighting the substantial exploration upside across a largely underexplored
district where many targets have seen little to no modern exploration.
*Metal
equivalents at Red Mountain are calculated using ratios with metal prices of US$2,750/tonne Zn, US$2,100/tonne Pb, US$8,880/tonne Cu,
US$1,850/oz Au, and US$23/oz Ag. Metal recoveries are based on metallurgical work returned of 90% Zn, 75% Pb, 70% Cu, 70% Ag, and 80%
Au. Silver Equivalent (AgEq g/t) = [Zn (%) x 47.81] + [Pb (%) x 30.43] + [Cu (%) x 119] + [Ag (g/t) x 1] + [Au (g/t) x 91.93]. ZnEq (%)
= [Zn (%) x 1] + [Pb (%) x 0.6364] + [Cu (%) x 2.4889] + [Ag (ppm) x 0.0209] + [Au (ppm) x 0.1923]
*Silver
Equivalent at Hughes is calculated using US$20/oz Ag, US$1,800/oz Au, with metallurgical recoveries of Ag - 90% and Au - 95%. AgEq =
(Ag grade x Ag recovery)+((Au grade x Au recovery) x (Au price / Ag price)).
Mogollon
Project Overview
Silver47’s
100%-owned Mogollon Project is located in southwestern New Mexico’s prolific Mogollon Mining District, the state’s largest
historic silver-producing district. The project hosts an inferred mineral resource estimate of 2.72 million tonnes grading 367 g/t silver
equivalent (AgEq), containing 32.1 million silver equivalent ounces. Recent drilling has confirmed exceptional high-grade mineralization
and highlights the project’s significant resource expansion potential. Notable results include hole MOG22-05 at the Consolidated
target, which intersected 31.0 meters grading 448 g/t silver equivalent (129 g/t silver and 3.88 g/t gold). The 7,730-acre Mogollon Project
hosts a district-scale vein field with approximately 77 kilometers of cumulative strike length, of which only 2.4 kilometers have been
systematically explored and drilled to date, providing a rare and unique opportunity for new discoveries and resource growth.
*Silver
Equivalent at Mogollon is calculated using US$20/oz Ag, US$1,800/oz Au, with metallurgical recoveries of Ag - 90% and Au - 95%. AgEq
= (Ag grade x Ag recovery)+((Au grade x Au recovery) x (Au price / Ag price)).

Pursuant
to the terms and conditions of the Arrangement Agreement, Silver47 shareholders will receive 0.1724 Bunker Hill Shares for each Silver47
Share held immediately prior to closing of the Transaction. Based on the last closing price of the Bunker Hill Shares on the TSX on August
20, 2026, the Exchange Ratio implies an aggregate equity value for Silver47 of approximately US$163,000,000 (C$225,000,000), on a fully
diluted, in-the-money basis.
Pursuant
to the Plan of Agreement, each Silver47 option (a “Silver47 Option”) outstanding immediately prior to the effective
time of the Arrangement (the “Effective Time”), whether vested or unvested, shall be exchanged for an option (each
a “Replacement Option”) to acquire from Bunker Hill, the number of Bunker Hill Shares as is equal to (rounded down
to the nearest whole number): (i) the number of Silver47 Shares subject to such Silver47 Option immediately prior to the Effective Time;
multiplied by (ii) the Exchange Ratio. The exercise price per Bunker Hill Share subject to a Replacement Option shall be an amount equal
to: (i) the exercise price per Silver47 Share subject to each such Silver47 Option immediately before the Effective Time; divided by
(ii) the Exchange Ratio, provided that the aggregate exercise price payable on any particular exercise of Replacement Options shall be
rounded up to the nearest whole cent. The Replacement Options shall be exercisable until the original expiry date of the Silver47 Option,
except that the term of any Replacement Options, including any outstanding Replacement Options held by or on behalf of an individual
that will not be continuing as a director, officer, employee or consultant of Bunker Hill or any of its affiliates (including Silver47)
following 60 days after the effective date of the Arrangement, shall be the lesser of (A) the current expiry date of the Silver47 Option,
