On September 18, 2025, Bunker Hill Mining Corp. (the “Company”) held its 2025 annual meeting of stockholders (the “Annual Meeting”). Pursuant to the vote described in Item 5.07 below, the stockholders of the Company approved at the Annual Meeting the amendment and restatement (the “Amended and Restated RSU Plan”) of the Company’s existing restricted stock unit incentive plan, with the only change being the increase of the maximum number of shares of common stock issuable thereunder from 33,909,921 shares to 92,699,433 shares (the “RSU Plan Amendment”). Upon such approval, the Amended and Restated RSU Plan became effective.

The foregoing description of the RSU Plan Amendment is not complete and is qualified in its entirety by reference to the text of the Amended and Restated RSU Plan, which is attached hereto as Exhibit 10.1.

The Board shall have full power and authority to take all actions and to make all determinations required or provided for under the Plan, any Award or any Award Agreement, and shall have full power and authority to take all such other actions and make all such other determinations not inconsistent with the specific terms and provisions of the Plan that the Board deems to be necessary or appropriate to the administration of the Plan, any Award or any Award Agreement. All such actions and determinations shall be by the affirmative vote of a majority of the members of the Board present at a meeting or by unanimous consent of the Board executed in writing in accordance with the Company’s articles and applicable law. The interpretation and construction by the Board of any provision of the Plan, any Award or any Award Agreement shall be final, binding and conclusive.

3.2 Committee

The Board from time to time may delegate to the Committee such powers and authorities related to the administration and implementation of the Plan, as set forth in Section 3.1 above and other applicable provisions, as the Board shall determine, other than the Board’s power and authority to grant awards or to issue Shares to Grantees upon the vesting of an Award, consistent with the articles of the Company and applicable law.

(i) Except as provided in Subsection (ii) and except as the Board may otherwise determine, the Committee, if any, appointed by the Board to administer the Plan shall consist of two or more Outside Directors of the Company who meet such requirements as may be established from time to time by the securities regulatory authorities for such incentive plans and who comply with the independence requirements of applicable securities regulatory policies.

(ii) The Board may also appoint one or more separate committees of the Board, each composed of one or more Directors who need not be Outside Directors, who may administer the Plan and may determine all terms of such Awards.

Notwithstanding the foregoing, the Board may not delegate its authority to grant Awards or to issue Shares to Grantees upon the vesting of an Award.

In the event that the Plan, any Award or any Award Agreement entered into hereunder provides for any action to be taken by or determination to be made by the Board, such action may be taken or such determination may be made by the Committee if the power and authority to do so has been delegated to the Committee by the Board as provided for in this Section 3.2. Unless otherwise expressly determined by the Board, any such action or determination by the Committee shall be final, binding and conclusive. To the extent permitted by law, the Committee may delegate its authority under the Plan to a member of the Board.

3.3 Terms of Awards

Subject to the other terms and conditions of the Plan, the Board shall have full and final authority to:

(i) designate Grantees;

(ii) determine the number of Shares to be subject to an Award;

(iii) establish the terms and conditions of each Award (including, but not limited to, the nature and duration of any restriction or condition (or provision for lapse thereof) relating to the vesting or forfeiture of an Award and any other terms or conditions), provided, however, that no Award may vest before the date that is one year following the applicable Grant Date, subject to acceleration as provided in Section 11.2;

(iv) prescribe the form of each Award Agreement evidencing an Award;

(iv) establish performance criteria; and

(v) amend, modify, or supplement the terms of any outstanding Award. Such authority specifically includes the authority, in order to effectuate the purposes of the Plan but without amending the Plan, to modify Awards to eligible Persons who are foreign nationals or are individuals who are employed outside Canada to recognize differences in local law, tax policy, or custom.

As a condition to any subsequent Award, the Board shall have the right, at its discretion, to require Grantees to return Awards previously made under the Plan to the Company. Subject to the terms and conditions of the Plan, any such new Award shall be upon such terms and conditions as are specified by the Board at the time the new Award is made. The Board shall have the right, in its discretion, to make Awards in substitution or exchange for any other award under another plan of the Company, any Affiliate, or any business entity to be acquired by the Company or an Affiliate. The Company may retain the right in an Award Agreement to cause a forfeiture of the gain realized by a Grantee on account of actions taken by the Grantee in violation or breach of or in conflict with any employment agreement, non-competition agreement, any agreement prohibiting solicitation of employees or clients of the Company or any Affiliate thereof or any confidentiality obligation with respect to the Company or any Affiliate thereof or otherwise in competition with the Company or any Affiliate thereof, to the extent specified in such Award Agreement applicable to the Grantee. Furthermore, the Company may, within 30 days, annul an Award if the Grantee is an Employee of the Company or an Affiliate thereof and is terminated for Cause. The grant of any Award shall be contingent upon the Grantee executing the appropriate Award Agreement.

3.4 No Liability

No member of the Board or of the Committee shall be liable for any action or determination made in good faith with respect to the Plan or any Award or Award Agreement.

3.5 Book Entry

Notwithstanding any other provision of this Plan to the contrary, the Company may elect to satisfy any requirement under this Plan for the delivery of share certificates through the use of book-entry.

3.6 Press Release

A grant of any Award under this Plan to a Director or Officer, and any amendment to an Award issued under this Plan to such Director or Officer, must be disclosed to the public by way of a news release that must be disseminated on the day the Award is granted or amended, as applicable.

4. SHARES SUBJECT TO THE PLAN

4.1 Maximum Number of Shares

Shares issued or to be issued under the Plan shall be authorized but unissued Shares. Subject to adjustment as provided in Section 11 hereof or as required by the Stock Exchange, the maximum number of Shares available for issuance under the Plan shall be 10% of the total number of issued and outstanding Shares as at July 17, 2025, and shall be fixed at 92,699,433 Shares. The number of Shares issued or to be issued under the Plan and all other Security Based Compensation Plans, at any time, shall not exceed 20% of the total number of the issued and outstanding Shares. If any Shares covered by an Award are settled in cash, forfeited, surrendered, cancelled or otherwise terminated prior to the delivery of any Shares subject thereto, then the number of Shares counted against the aggregate number of Shares available under the Plan with respect to such Award shall, to the extent of any such settlement, forfeiture, surrender, cancellation or termination, again be available for making Awards under the Plan. The Board shall have the right to substitute or assume Awards in connection with mergers, reorganizations, separations, or other transactions. The number of Shares reserved pursuant to this Section 4.1 may be increased by the corresponding number of Awards assumed and, in the case of a substitution, by the net increase in the number of Shares subject to Awards before and after the substitution.

4.2 Restrictions on Issuances

Unless Disinterested Shareholder Approval has been obtained, the maximum aggregate number of Shares which may be issuable under the Plan and any other Security Based Compensation Plan on and after the effective date of the Plan, within any 12-month period:

(i) to Insiders (as a group), shall not exceed 10% of the issued and outstanding Shares, calculated as at the date any Security Based Compensation is granted or issued to any Insider; and

(ii) to any one Grantee, must not exceed 5% of the then issued and outstanding Shares, calculated as at the date any Security Based Compensation is granted or issued to the Grantee.

Notwithstanding the foregoing:

(i) unless Disinterested Shareholder Approval has been obtained, the maximum aggregate number of Shares issuable pursuant to all Security Based Compensation granted or issued to Insiders (as a group), at any time, cannot exceed 10% of the issued and outstanding Shares;

(ii) the maximum aggregate number of Shares issuable pursuant to all Security Based Compensation granted or issued to any one Consultant, cannot exceed 2% of the issued and outstanding Shares in a 12-month period, calculated as at the date any Security Based Compensation is granted or issued to the Consultant; and

(iii) the annual grant of Awards under this Plan to any one non-Employee Director, in combination with all other Security Based Compensation granted to such non-Employee Director, shall be limited to an annual equity award value (based on grant date fair value as determined by the Board) of $150,000 per non-Employee Director, provided that the total value (based on grant date fair value as determined by the Board) of stock options issuable to any one non-Employee Director in any one year period shall not exceed $100,000.

5. EFFECTIVE DATE, DURATION AND AMENDMENTS

5.1 Effective Date

The Plan will be effective upon the approval of the Plan by the Board; provided that no Shares may be issued under the Plan until and unless all required Stock Exchange, regulatory and shareholder approvals have been obtained with the respect to the issuances of Shares hereunder.

5.2 Amendment and Termination of the Plan

The Board may, at any time and from time to time, amend the Plan or suspend, extend or terminate the Plan in whole or in part, subject to the requirements of the Stock Exchange(s). No such amendment, suspension or termination shall adversely affect the rights of any Grantee at the time of such amendment, suspension or termination with respect to outstanding and unredeemed Restricted Stock Units credited to such Grantee without the consent of the affected Grantee. An amendment shall be contingent on Disinterested Shareholder Approval to the extent stated by the Board, required by applicable law or required by applicable Stock Exchange listing requirements. Notwithstanding the foregoing, the Plan shall not be amended to (i) remove or exceed the 10% Insider participation limit, (ii) increase the maximum number of Shares made available from treasury under the Plan, (iii) extend the term of an RSU for the sole benefit of an Insider, (iv) designate additional categories of Grantees, (v) permit the transfer or assignment of an RSU other than for normal estate settlement purposes, or (vi) change this amendment provision without Disinterested Shareholder Approval.

However, the Company may, without notice, at any time and from time to time, and without Disinterested Shareholder Approval, amend the Plan or any provisions thereof in such manner as the Company, in its sole discretion, determines appropriate, including, without limitation: (i) amendments of a housekeeping nature, including to correct any ambiguity, defective provision, error or omission in the provisions of the Plan; (ii) changes to vesting provisions of Restricted Stock Units (with prior TSX-V written approval); (iii) changes to the term of the Plan or Awards made hereunder; or (iv) changes to performance criteria will not require Disinterested Shareholder Approval.

If the Board terminates the Plan, no new Restricted Stock Units will be awarded to any Grantee, but outstanding and unredeemed previously credited Restricted Stock Units shall remain outstanding.

6. AWARD ELIGIBILITY AND LIMITATIONS

6.1 Service Providers

Subject to this Section 6, Awards may be made under the Plan to any Grantee or Service Provider, as the Board shall determine and designate from time to time. The Company and the Grantee of Restricted Stock Units are responsible for ensuring and confirming that the Grantee of Restricted Stock Units is a bona fide Service Provider, if applicable.

6.2 Investor Relations Activities

Persons providing Investor Relations Activities to the Company shall not be eligible to receive any Restricted Stock Units under the Plan.

6.3 Successive Awards

An eligible Person may receive more than one Award, subject to such restrictions as are provided herein.

6.4 Stand-Alone, Additional, Tandem, and Substitute Awards

Awards granted under the Plan may, in the discretion of the Board, be granted either alone or in addition to, in tandem with, or in substitution or exchange for, any other Award or any award granted under another plan of the Company, any Affiliate, or any business entity to be acquired by the Company or an Affiliate, or any other right of a Grantee to receive payment from the Company or any Affiliate. Such additional, tandem, and substitute or exchange Awards may be granted at any time. If an Award is granted in substitution or exchange for another Award, the Board shall require the surrender of such other Award in consideration for the grant of the new Award.

7. AWARD AGREEMENT

Each Award granted pursuant to the Plan shall be evidenced by an Award Agreement, in such form or forms as the Board shall from time to time determine. Award Agreements granted from time to time or at the same time need not contain similar provisions but shall be consistent with the terms of the Plan. By entering into an Award Agreement as described in this Section 7, each Grantee shall be deemed conclusively to have accepted and consented to all terms of this Plan and all bona fide actions or decisions made by the Committee. Such terms and consent shall also apply to and be binding on the legal representative, beneficiaries, heirs and successors of each Grantee.

8. TERMS AND CONDITIONS OF RESTRICTED STOCK UNITS

8.1 Grant of Restricted Stock Units

Awards shall be in the form of Restricted Stock Units. Subject to the restrictions and vesting provisions provided in Section 8.2, each RSU shall entitle the Grantee to receive one Share.

8.2 Restrictions and Vesting

At the time a grant of Restricted Stock Units is made, the Board may, in its sole discretion, establish a period of time (a “Vesting period”) applicable to such Restricted Stock Units. Each Award of Restricted Stock Units may be subject to a different vesting period. The Board may, in its sole discretion, at the time a grant of Restricted Stock Units is made, prescribe restrictions in addition to or other than the expiration of the vesting period, including the satisfaction of corporate or individual performance objectives, which may be applicable to all or any portion of the Restricted Stock Units in accordance with Sections 9.1 and 9.2. Notwithstanding the foregoing, (i) Restricted Stock Units shall vest in full from a period beginning on the Grant Date to the date which is not later than three (3) years from the Grant Date; (ii) Restricted Stock Units for which vesting may be accelerated by achieving performance targets shall vest in full from a period beginning on the Grant Date to the date which is not later than three (3) years from the Grant Date; (iii) at the election of an Outside Director at the time the Award is granted, Restricted Stock Units may vest in full from a period beginning on the Grant Date to the date which is not later than three (3) years from the Grant Date, and (b) if no election is made, upon the earlier of a Change of Control in accordance with Section 11.2 or his or her resignation from the Board; and (iv) except for the cessation of a Service Provider’s position as a Service Provider, in no case shall a Restricted Stock Unit vest within one (1) year from the Grant Date, subject to Section 11.2.

Restricted Stock Units may not be sold, transferred, assigned, pledged or otherwise encumbered or disposed of (other than to the Grantee’s beneficiary or estate, as the case may be, upon the death of the Grantee) during the vesting period.

Upon the death of a Grantee, any RSUs granted to such Grantee which, prior to the Grantee’s death, have not vested, will immediately vest, subject to the pass of one (1) year from the Grant Date, and the Grantee’s estate shall be entitled to receive payment in accordance with Section 8.6 hereof. Notwithstanding any other provision in the Plan, the period in which the Grantee’s estate may make such a claim of entitlement must not exceed one (1) year from the date of the Grantee’s death.

8.3 Restricted Stock Unit Accounts

An account will be maintained by the Secretary of the Company, or such other Officer as the Board may designate, in the name and for the benefit of the Grantee, in which will be recorded the number of RSUs granted to the Grantee, the Grant Date and expiry date of the RSUs.

8.4 Rights of Holders of Restricted Stock Units

8.4.1 Voting and Dividend Rights

Grantees of Restricted Stock Units shall have no rights as shareholders of the Company. The Board may provide in an Award Agreement evidencing a grant of Restricted Stock Units that the Grantee shall be entitled to receive, upon the Company’s payment of a cash dividend on its outstanding Shares, a cash payment for each Restricted Stock Unit granted equal to the per-share dividend paid on the outstanding Shares. Such Award Agreement may also provide that such cash payment will be deemed reinvested in additional Restricted Stock Units at a price per unit equal to the Fair Market Value of the Shares on the date that such dividend is paid. Any grant of additional Restricted Stock Units pursuant to this Section 8.4.1 must be included in the maximum number of Shares subject to the Plan pursuant to Section 4 of the Plan. If there are not a sufficient number of Shares available under the Plan to satisfy the grant of additional Restricted Stock Units, notwithstanding any provision in the applicable Award Agreement, the Company shall satisfy the obligation by way of cash payment.

8.4.2 Creditor’s Rights

A Grantee shall have no rights other than those of a general creditor of the Company. Restricted Stock Units represent an unfunded and unsecured obligation of the Company, subject to the terms and conditions of the applicable Award Agreement.

8.5 Termination of Service

Unless the Board otherwise provides in an Award Agreement or in writing after the Award Agreement is issued, subject to the requirements of the Stock Exchange(s), upon the termination of a Grantee’s Service, any RSUs granted to a Grantee that have not vested and will not vest within 30 days from the date of termination, or with respect to which all applicable restrictions and conditions have not lapsed, shall immediately be deemed forfeited. Upon forfeiture of RSUs, the Grantee shall have no further rights with respect to such Award, including but not limited to any right to receive dividends with respect to the RSUs. For greater certainty, all Awards must expire within 12 months following the Grantee ceasing to be an eligible participant under the Plan.

8.5.1 Termination for Cause and Voluntary Resignation

If a Grantee ceases to be an Employee as a result of termination for Cause, then effective as of the date notice is given to the Grantee of termination, the Company may, within 30 days, annul an award if the Grantee is an Employee of the Company or an Affiliate thereof. If a Grantee’s employment is terminated with cause, or at the option of the Grantee, unless the Board otherwise provides in an Award Agreement or in writing after the Award Agreement is issued, any RSUs that have not vested and will not vest within 30 days from the date of termination, or with respect to which all applicable restrictions and conditions have not lapsed, shall immediately be deemed forfeited.

8.6 Delivery of Shares

Upon the expiration or termination of the vesting period and the satisfaction of any other restrictions prescribed by the Board, the RSUs shall vest and shall be settled in Shares (net of any Applicable Withholding Tax) issued by the Company from treasury and, unless otherwise provided in the Award Agreement, a share certificate for that number of Shares equal to the number of vested RSUs shall be delivered, free of all such restrictions, to the Grantee or the Grantee’s beneficiary or estate, as the case may be.

Settlement of RSUs shall be in Shares issued by the Company from treasury. The Committee shall specify the circumstances in which Awards shall be made or forfeited in the event of termination of Service by the Grantee prior to vesting.

8.7 TSX-V Hold Period and Resale Restrictions

If required by the TSX-V Policies, the certificate representing any Shares issued under the Plan (if exercised prior to the expiry of the Exchange Hold Period) will bear the following Exchange Hold Period legend:

“Without prior written approval of TSX Venture Exchange and compliance with all applicable securities legislation, the securities represented by this certificate may not be sold, transferred, hypothecated or otherwise traded on or through the facilities of TSX Venture Exchange or otherwise in Canada or to or for the benefit of a Canadian resident until [insert date that is four months and a day after the distribution date].”

9. TERMS AND CONDITIONS OF AWARDS

9.1 Performance Conditions

The granting and vesting of RSUs may be subject to such performance conditions as may be specified by the Board in the Award Agreement. The Board may use such business criteria and other measures of performance as it may deem appropriate in establishing any performance conditions and may exercise its discretion to reduce the amounts payable under any Award subject to performance conditions.

9.2 Performance Goals Generally

The performance goals for Awards shall consist of one or more business criteria and a targeted level or levels of performance with respect to each of such criteria, as specified by the Committee consistent with this Section 9.2. Performance goals shall be objective and shall otherwise meet the requirements that the level or levels of performance targeted by the Committee result in the achievement of performance goals being “substantially uncertain”. The Committee may determine that Awards shall vest upon achievement of any one performance goal or that two or more of the performance goals must be achieved as a condition to the vesting of an Award. Performance goals may differ for Awards granted to any one Grantee or to different Grantees.

9.3 Business Criteria

The Board, in its sole discretion, may establish business criteria for the purpose of establishing performance goals in accordance with Section 9.1, including but not limited to, one or more of the following business criteria for the Company, on a consolidated basis, and/or specified Subsidiaries or business units of the Company (except with respect to the total shareholder return and earnings per share criteria): (1) total shareholder return; (2) such total shareholder return as compared to total return (on a comparable basis) of a publicly available index such as, but not limited to, the S&P/TSX Composite Index; (3) past service to the Company; (4) net income; (5) pre-tax earnings; (6) earnings before interest expense, taxes, depreciation and amortization; (7) pre-tax operating earnings after interest expense and before bonuses, service fees, and extraordinary or special items; (8) operating margin; (9) earnings per share; (10) return on equity; (11) return on capital; (12) return on investment; (13) operating earnings; (14) working capital; (15) ratio of debt to shareholders’ equity; (16) revenue; and (17) free cash flow and free cash flow per share. Business criteria may be measured on an absolute basis or on a relative basis (i.e., performance relative to peer companies) and on a GAAP or non-GAAP basis.

9.4 Timing For Establishing Performance Goals

Performance goals shall be established not later than 90 days after the beginning of any performance period applicable to such Awards, or at such other date as may be determined by the Board.

9.5 Written Determinations

All determinations by the Committee as to the establishment of performance goals, the amount of any Award and as to the achievement of performance goals relating to Awards, and the amount of any final Awards, shall be made in writing.

10. REQUIREMENTS OF LAW

10.1 General

The Plan shall comply with the provisions of any applicable law or regulation of any governmental authority, including without limitation any federal, state or provincial securities laws or regulations and the requirements of any stock exchange having jurisdiction. The failure to comply with such laws or regulations, including without limitation the Securities Act, may result in a termination of the Plan and/or the forfeiture of previously granted RSUs.

10.2 TSX Venture Exchange Policy

The Plan is subject to TSX-V Policy 4.4.

11. EFFECT OF CHANGES IN CAPITALIZATION

11.1 Changes in Shares

If the number of outstanding Shares is increased or decreased or the Shares are changed into or exchanged for a different number or kind of shares or other securities of the Company on account of any recapitalization, reclassification, stock split, reverse split, combination of shares, exchange of shares, stock dividend or other distribution payable in capital stock, or other increase or decrease in such shares effected without receipt of consideration by the Company occurring after the effective date of the Plan, the number and kinds of shares for which Awards may be made under the Plan shall be adjusted proportionately and accordingly by the Company. In addition, the number and kind of shares for which Awards are outstanding shall be adjusted proportionately and accordingly so that the proportionate interest of the Grantee immediately following such event shall, to the extent practicable, be the same as immediately before such event. Notwithstanding the foregoing, in the event of any distribution to the Company’s shareholders of securities of any other entity or other assets (including an extraordinary cash dividend but excluding a non-extraordinary dividend payable in cash or in shares of the Company) without receipt of consideration by the Company, the Company may, in such manner as the Company deems appropriate, adjust the number and kind of shares subject to outstanding Awards.

11.2 Change of Control

Notwithstanding the conditions as to vesting of Restricted Stock Units contained in Section 8.2 or in any individual Award Agreement, and subject to prior approval of the Stock Exchange if required, upon the occurrence of a Change of Control, all outstanding Restricted Stock Units shall be deemed to have vested, and all restrictions and conditions applicable to such Restricted Stock Units shall be deemed to have lapsed and the Shares subject to such Restricted Stock Units shall be issued and delivered (net of any Applicable Withholding Tax), immediately prior to the occurrence of such Change of Control.

11.3 Adjustments

Adjustments under Section 11.1 relating to Shares or securities of the Company, subject to prior TSX-V approval, shall be made by the Board, whose determination in that respect shall be final, binding and conclusive. For greater certainty, TSX-V approval will not be required for any stock split or reverse split. No fractional Shares or other securities shall be issued pursuant to any such adjustment, and any fractions resulting from any such adjustment shall be eliminated in each case by rounding downward to the nearest whole Share. The Board may provide in the Award Agreement at the time of grant, or any time thereafter with the consent of the Grantee, for different provisions to apply to an Award in place of those described in Section 11.1 and this Section 11.3.

11.4 No Limitations on Company

The making of Awards pursuant to the Plan shall not affect or limit in any way the right or power of the Company to make adjustments, reclassifications, reorganizations, or changes of its capital or business structure or to merge, consolidate, dissolve, or liquidate, or to sell or transfer all or any part of its business or assets.

12. GENERAL PROVISIONS

12.1 Disclaimer of Rights

No provision in the Plan or in any Award or Award Agreement shall be construed to confer upon any Person the right to remain in the employ or service of the Company or any Affiliate, or to interfere in any way with any contractual or other right or authority of the Company either to increase or decrease the compensation or other payments to any Person at any time, or to terminate any employment or other relationship between any Person and the Company. In addition, notwithstanding anything contained in the Plan to the contrary, unless otherwise stated in the applicable Award Agreement, no Award granted under the Plan shall be affected by any change of duties or position of the Grantee, so long as such Grantee continues to be an Officer, Director, Consultant or Employee of the Company or an Affiliate. The obligation of the Company to issue Shares or pay any benefits pursuant to this Plan shall be interpreted as a contractual obligation only in respect of those amounts described herein, in the manner and under the conditions prescribed herein. The Plan shall in no way be interpreted to require the Company to transfer any amounts to a third-party trustee or otherwise hold any amounts in trust or escrow for payment to any Grantee or beneficiary under the terms of the Plan.

12.2 Nonexclusivity of the Plan

Neither the adoption of the Plan nor the submission of the Plan to the Disinterested Shareholders for approval shall be construed as creating any limitations upon the right and authority of the Board to adopt such other Security Based Compensation Plans as the Board in its discretion determines desirable. The adoption of any such other Security Based Compensation Plan shall be subject to prior TSX-V approval.

12.3 Tax Matters and Applicable Withholding Taxes

The Company or an Affiliate, as applicable, does not assume any responsibility for or in respect of the tax consequences of the receipt by Grantees of Restricted Stock Units, or payments received by Grantees pursuant to this Plan. The Company or an Affiliate, as applicable, is authorized to deduct such taxes and other amounts as it may be required or permitted by law to withhold (the “Applicable Withholding Tax”), in such manner (including, without limitation, by withholding or selling Shares otherwise issuable to Grantees, on such terms as the Company determines) as it determines so as to ensure that it will be able to comply with the applicable provisions of any federal, provincial, state or local law relating to the withholding of tax or other required deductions, or the remittance of tax or other obligations. At the time of such vesting, lapse, or exercise, the Grantee shall pay to the Company or the Affiliate, as applicable, any amount that the Company or the Affiliate may reasonably determine to be necessary to satisfy such withholding obligation. The Company or an Affiliate, as applicable, may require Grantees, as a condition of receiving amounts to be paid to them under this Plan, to deliver undertakings to, or indemnities in favour of, the Company or an Affiliate, as applicable, respecting the payment by such Grantees of applicable income or other taxes. This section will not supersede the requirements under TSX-V Policy 4.4 nor potentially result in the alteration of the exercise price.

12.4 Captions

The use of captions in this Plan or any Award Agreement is for the convenience of reference only and shall not affect the meaning of any provision of the Plan or such Award Agreement.

12.5 Other Provisions

Each Award granted under the Plan may contain such other terms and conditions not inconsistent with the Plan as may be determined by the Board, in its sole discretion.

12.6 Number and Gender

With respect to words used in this Plan, the singular form shall include the plural form, the masculine gender shall include the feminine gender, etc., as the context requires.

12.7 Severability

If any provision of the Plan or any Award Agreement shall be determined to be illegal or unenforceable by any court of law in any jurisdiction, the remaining provisions hereof and thereof shall be severable and enforceable in accordance with their terms, and all provisions shall remain enforceable in any other jurisdiction.

12.8 Governing Law

The validity and construction of this Plan and the instruments evidencing the Award hereunder shall be governed by the laws of the Province of Ontario and the federal laws of Canada applicable herein, other than any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of this Plan and the instruments evidencing the Awards granted hereunder to the substantive laws of any other jurisdiction.

12.9 No Representation or Warranty

The Company makes no representation or warranty as to the future market value of any Shares issued in accordance with the provisions of the Plan.

12.10 Conflict

In the event of any conflict between the provisions of this Plan and an Award Agreement, the provisions of this Plan shall govern.

12.11 Limitation on Rights

Nothing in this Plan shall confer on any Employee, Consultant, Director, Officer or other Person any right to be designated as a Grantee under the Plan or to be granted any Restricted Stock Units. There is no obligation for uniformity of treatment of eligible Persons under the Plan or any group of Employees, Consultants, Director, Officers or other Persons, whether based on salary or compensation, grade or level or organizational position or level or otherwise. A grant of Restricted Stock Units to a Grantee on one or more Award Dates shall not be construed to create a right to a grant of Restricted Stock Units on a subsequent Award Date.

12.12 Time of Essence

Time is of the essence of this Plan and of each Award Agreement. No extension of time will be deemed to be or to operate as a waiver of the essentiality of time.

Approved by the Board on August 22, 2025.

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.

Forward-looking statements in this news release include, but are not limited to, statements regarding the Company’s objectives, goals or future plans, including the restart and development of the Bunker Hill Mine, and the achievement of future short-term, medium-term and long-term operational strategies.

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 SEC and with applicable Canadian securities regulatory authorities, and the following: the Company’s ability to raise additional capital for project activities on acceptable terms or at all; Bunker Hill’s ability to operate as a going concern and its history of losses; 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; 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; 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. 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.
