INFORMATION CIRCULAR

FOR THE 2025 ANNUAL GENERAL MEETING OF SHAREHOLDERS

This information is given as of November 6, 2025, unless otherwise stated.

SOLICITATION OF PROXIES

The Company is conducting the Meeting virtually. Registered shareholders and validly appointed proxyholders may attend the Meeting via Zoom at:

https://us06web.zoom.us/j/84663025034?pwd=3PZCs12EFIJNpGHNjBhAkswc0wO7xv.1

Meeting ID: 846 6302 5034

Passcode: 886722

This Information Circular (the "Information Circular") is furnished in connection with the solicitation of proxies by the management of METALSOURCE MINING INC. (the "Company") for use at the annual general meeting (the "Meeting") of the shareholders of the Company, to be held at the time and place and for the purposes set forth in the accompanying notice of meeting (the "Notice") and at any adjournment thereof.

These securityholder materials are being sent to both registered and non-registered owners of the securities. If you are a non-registered owner, and the Company or its agent has sent these materials directly to you, your name and address and information about your holdings of securities have been obtained in accordance with applicable securities regulatory requirements from the intermediary holding on your behalf.

By choosing to send these materials to you indirectly, the intermediary holding on your behalf has assumed responsibility for: (i) delivering these materials to you; and (ii) executing your proper voting instructions. Please return your voting instructions as specified in the request for voting instructions.

PERSONS OR COMPANIES MAKING THE SOLICITATION

The enclosed instrument of proxy (the "Proxy") is solicited by management. Solicitations will be made by mail and possibly supplemented by telephone or other personal contact to be made without special compensation by regular officers and employees of the Company. The Company may reimburse shareholders' nominees or agents (including brokers holding shares on behalf of clients) for the cost incurred in obtaining authorization from their principals to execute the Proxy. The cost of solicitation will be borne by the Company. None of the directors of the Company has advised management in writing that they intend to oppose any action intended to be taken by management as set forth in this Information Circular.

APPOINTMENT AND REVOCATION OF PROXIES

Solicitation of Proxies

The solicitation of proxies will be primarily by mail, but proxies may be solicited personally or by telephone by directors, officers and employees of the Company. The Company will bear all costs of this solicitation. We have arranged for intermediaries to forward the meeting materials to beneficial


owners of the common shares held of record by those intermediaries and we will reimburse the intermediaries for their reasonable fees and disbursements in that regard.

Appointment of Proxyholders

The individuals named in the accompanying Proxy are officers and/or directors of the Company. If you are a shareholder entitled to vote at the Meeting, you have the right to appoint a person or company other than either of the persons designated in the Proxy, who need not be a shareholder, to attend and act for you and on your behalf at the Meeting. You may do so either by inserting the name of that other person in the blank space provided in the Proxy or by completing and delivering another suitable form of proxy. If your shares are held in physical (i.e. paper) form and are registered in your name, then you are a registered shareholder. However, if, like most shareholders, you keep your shares in a brokerage account, then you are a beneficial shareholder (the “Beneficial Shareholder”). The process for voting is different for registered and Beneficial Shareholders, and you will need to carefully read the instructions below.

Voting by Proxyholder

The persons named in the Proxy will vote or withhold from voting the shares represented thereby in accordance with your instructions on any ballot that may be called for. If you specify a choice with respect to any matter to be acted upon, your shares will be voted accordingly. The Proxy confers discretionary authority on the persons named therein with respect to:

(a) each matter or group of matters identified therein for which a choice is not specified, other than the appointment of an auditor and the election of directors;
(b) any amendment to or variation of any matter identified therein; and
(c) any other matter that properly comes before the Meeting.

In respect of a matter that properly comes before the Meeting and for which a choice is not specified in the Proxy, the persons named in the Proxy will vote the shares represented by the Proxy in their discretion.

Registered Shareholders

Registered shareholders may wish to vote by Proxy whether or not they are able to attend the Meeting in person virtually. Registered shareholders electing to submit a Proxy may do so by:

(a) completing, dating and signing the enclosed Proxy and returning it to the Company's transfer agent, Endeavor Trust Corporation ("Endeavor"), at their offices located at 702-777 Hornby Street, Vancouver, BC, V6Z 1S4, email to [email protected] or fax at 604-559-8908; or
(b) using the internet at Endeavor's website, https://www.eproxy.ca/auth/login. Registered shareholders must follow the instructions that appear on the screen and refer to the enclosed Proxy for the holder's control number and password.

In all cases ensuring that the Proxy is received at least 48 hours (excluding Saturdays, Sundays and holidays) before the Meeting or any adjournment thereof at which the proxy is to be used.

Beneficial Shareholders

The following information is of significant importance to shareholders who do not hold shares in their own name. Beneficial Shareholders should note the only proxies that can be


recognized and acted upon at the Meeting are those deposited by registered shareholders (those whose names appear on the records of the Company as the registered holders of Shares) or as set out in the following disclosure.

If shares are listed in an account statement provided to a shareholder by a broker, then in almost all cases those shares will not be registered in the shareholder's name on the records of the Company. Such shares will more likely be registered under the name of the shareholder's broker or an agent of that broker. In Canada, the vast majority of such Shares are registered under the name of CDS & Co. (the registration name for The Canadian Depository for Securities Limited, which acts as nominee for many Canadian brokerage firms). In the United States of America (the "U.S." or the "United States") the vast majority of such shares are registered under the name of Cede & Co. as nominee for The Depository Trust Company (which acts as depository for many U.S. brokerage firms and custodian banks).

Intermediaries are required to seek voting instructions from Beneficial Shareholders in advance of shareholders' meetings. Every intermediary has its own mailing procedures and provides its own return instructions to clients.

There are two kinds of Beneficial Shareholders - those who object to their name being made known to the issuers of securities which they own (called "OBOs" for "Objecting Beneficial Owners") and those who do not object to the issuers of the securities they own knowing who they are (called "NOBOs" for "Non-Objecting Beneficial Owners").

These securityholder materials are sent to both registered and non-registered (beneficial) owners of the securities of the Company. If you are a non-registered owner, and the Company or its agent sent these materials directly to you, your name, address and information about your holdings of securities, were obtained in accordance with applicable securities regulatory requirements from the intermediary holding securities on your behalf.

Beneficial Shareholders who are OBOs should follow the instructions of their intermediary carefully to ensure that their shares are voted at the Meeting.

Management of the Company does not intend to pay for intermediaries to forward to objecting beneficial owners ("OBOs") under NI 54-101 the proxy-related materials and Form 54-101F7 - Request for Voting Instructions Made by Intermediary, and, in the case of an OBO, the OBO will not receive the materials unless the OBO's intermediary assumes the cost of delivery.

The form of proxy supplied to you by your broker will be similar to the proxy provided to registered shareholders by the Company. However, its purpose is limited to instructing the intermediary on how to vote on your behalf. Most brokers now delegate responsibility for obtaining instructions from clients to Broadridge Financial Solutions Inc. ("Broadridge") in Canada and in the United States. Broadridge mails a Voting Instruction Form ("VIF") in lieu of a proxy provided by the Company. The VIF will name the same persons as the Company's Proxy to represent you at the Meeting. You have the right to appoint a person (who need not be a Beneficial Shareholder of the Company), different from the persons designated in the VIF, to represent your shares at the Meeting, and that person may be you. To exercise this right, insert the name of your desired representative (which may be you) in the blank space provided in the VIF. Once you have completed and signed your VIF return it to Broadridge by mail or facsimile, or deliver your voting instructions to Broadridge by phone or via the internet, in accordance with Broadridge's instructions. Broadridge tabulates the results of all instructions received and provides appropriate instructions respecting the voting of shares to be represented at the Meeting. If you receive a VIF from Broadridge, it must be completed and returned to Broadridge, in accordance with Broadridge's instructions, well in advance of the Meeting in order to: (a) have your shares voted at the Meeting as per your instructions; or (b) have an alternate representative chosen by you duly appointed to attend and vote your shares at the Meeting.


Notice to Shareholders in the United States

The solicitation of proxies in this Information Circular involves securities of an issuer located in Canada and is being effected in accordance with the corporate laws of the Province of British Columbia, Canada and the securities laws of certain provinces of Canada. The proxy solicitation rules under the United States Securities Exchange Act of 1934, as amended, are not applicable to the Company or this solicitation, and this solicitation has been prepared in accordance with the disclosure requirements of the securities laws of the provinces of Canada. Shareholders should be aware that disclosure requirements under the securities laws of the applicable provinces of Canada differ from the disclosure requirements under United States securities laws.

The enforcement by shareholders of civil liabilities under United States federal securities laws may be affected adversely by the fact that the Company is incorporated under the Business Corporations Act (British Columbia), as amended, certain of its directors and executive officers are residents of Canada and a substantial portion of the assets of such persons are located outside of the United States. Shareholders may not be able to sue a foreign company or its officers or directors in a foreign court for violations of United States federal securities laws. It may be difficult to compel a foreign company and its officers and directors to subject themselves to a judgment by a United States court.

Revocation of Proxies

In addition to revocation in any other manner permitted by law, a registered shareholder who has given a Proxy may revoke it by:

(a) executing a Proxy bearing a later date or by executing a valid notice of revocation, either of the foregoing to be executed by the registered shareholder or the registered shareholder's authorized attorney in writing or, if the shareholder is a corporation, under its corporate seal by an officer or attorney duly authorized, and by delivering the Proxy bearing a later date to Endeavor at its address shown on the preceding page, or at the address of the Company at Suite 700 – 838 West Hastings Street, Vancouver, British Columbia, V6C 0A6, at any time up to and including the last business day that precedes the day of the Meeting or, if the Meeting is adjourned, the last business day that precedes any reconvening thereof, or to the chairperson of the Meeting on the day of the Meeting or any reconvening thereof, or in any other manner provided by law; or

(b) attending the Meeting in person virtually and voting the registered shareholder's shares.

A revocation of a Proxy will not affect a matter on which a vote is taken before the revocation.

Stock Options and Other Incentive Plans

On October 25, 2023, the Company adopted a stock option plan (the "Option Plan"), to replace the Company's current stock option plan, and a restricted share unit plan (the "RSU Plan").

The purpose of granting such Options and RSUs is to assist the Company in compensating, attracting, retaining and motivating such persons and to closely align the personal interest of such persons to that of the Company's shareholders. The allocation of Options and RSUs under the Option Plan and RSU Plan is determined by the Board of Directors (the "Board") which, in determining such allocations, considers such factors as previous grants to individuals, overall Company performance, peer company performance, share price performance, the business environment and labour market, the role and performance of the individual in question and, in the case of grants to non-executive directors, the amount of time directed to the Company's affairs and time expended for serving on the Company's audit committee (the "Audit Committee").

Oversight and Description of Director and NEO Compensation

The Board governs the Company’s compensation program, which is designed to be competitive with similar junior mineral exploration companies and to recognize and reward executive and director performance consistent with the success of the Company. The Board’s philosophy is to ensure that the Company’s goals and objectives, as applied to the actual compensation paid to the directors and NEOs, are aligned with the Company’s overall business objectives and with shareholders’ interests.

The Company’s compensation objectives include the following:

  • to assist the Company in attracting and retaining highly-qualified individuals;
  • to create among directors, officers and consultants a sense of ownership in the Company and to align their interests with those of the shareholders; and
  • to ensure competitive compensation that is also financially affordable for the Company.

The compensation program is designed to provide competitive levels of compensation. The Company recognizes the need to provide a total compensation package that will attract and retain qualified and experienced executives as well as align the compensation level of each executive to


that executive's level of responsibility. In general, the Company's NEOs may receive compensation that is comprised of three components:

  • Salary, wages or contractor payments;
  • Option and RSU grants; and/or
  • Bonuses.

The objective and reason for this system of compensation is to allow the Company to remain competitive compared to its peers in attracting experienced personnel. The base salary of an NEO is intended to attract and retain executives by providing a reasonable amount of non-contingent remuneration.

The base salary review of each NEO takes into consideration the current competitive market conditions, experience, proven or expected performance, and the particular skills of the NEO. The Board relies on the general experience of its members in setting base salary amounts.

Option and RSU grants are designed to reward the NEOs and directors for success on a similar basis as the shareholders of the Company, although the level of reward provided by a particular Option and RSU grant is dependent upon the volatile stock market.

Any bonuses paid to the NEOs are allocated on an individual basis related to the review by the Board of the work planned during the year and the work achieved during the year. The bonuses are paid to reward work done above the base level of expectations set by the base salary, wages or contractor payments.

Pension Disclosure

The Company has no pension plans that provide for payments or benefits to any NEO at, following or in connection with retirement. The Company also does not have any deferred compensation plans relating to any NEO.

SECURITIES AUTHORIZED FOR ISSUANCE UNDER EQUITY COMPENSATION PLANS

The following table sets forth details of the Company's compensation plans under which equity securities of the Company were authorized for issuance at the end of the Company's financial year ended June 30, 2025:

INDEBTEDNESS OF DIRECTORS AND EXECUTIVE OFFICERS

No executive officer, director, employee, former executive officer, former director, former employee, proposed nominee for election as a director, or associate of any such person has been indebted to the Company or its subsidiaries at any time since the commencement of the Company's last completed financial year. No guarantee, support agreement, letter of credit or other similar arrangement or understanding has been provided by the Company or its subsidiaries at any time since the beginning of the most recently completed financial year with respect to any indebtedness of any such person.

CORPORATE GOVERNANCE

Further to National Instrument 58-101 Disclosure of Corporate Governance Practices, and the Company's status as a "Venture Issuer", the following is a description of the Company's corporate governance practices.

Board of Directors

The Board facilitates its exercise of independent supervision over the Company's management through meetings of the Board. Alex Bugden and Timothy Ko do not have any other material relationship to the Company that would interfere with his ability to act in the best interests of the Company and are therefore considered to be independent directors. Joseph Cullen, President & CEO, would not be considered an independent director as he is an executive officer of the Company.

Directorships

Certain directors are presently directors in one or more other reporting issuers, as follows:

Director Other Issuers
Joseph Cullen Golden Spike Resources Corp.
Naughty Ventures Corp.
Alex Bugden Sorrento Resources Ltd
Timothy Ko Entheon Biomedical Corp.
Naughty Ventures Corp.

Orientation and Continuing Education

The Board briefs all new directors with respect to the policies of the Board and other relevant corporate and business information. The Company does not provide any continuing education to directors.

Ethical Business Conduct

The Board has found that the fiduciary duties placed on individual directors by the Company's governing corporate legislation and the common law and the restrictions placed by applicable corporate legislation on an individual director's participation in decisions of the Board in which the director has an interest have been sufficient to ensure that the Board operates independently of management and in the best interests of the Company.

Nomination of Directors

The Board is responsible for identifying individuals qualified to become new Board members and recommending to the Board new director nominees for the next annual meeting of the shareholders.


New nominees must have a track record in general business management, special expertise in an area of strategic interest to the Company, the ability to devote the time required, show support for the Company's mission and strategic objectives, and a willingness to serve.

Compensation

The Board is responsible for setting compensation paid to directors and executive officers, establishing and reviewing incentive plans for directors, officers and management, providing guidance to the Company on corporate governance matters. The process determining compensation includes comparison with compensation in entities comparable to the Company.

Other Board Committees

The Board has no other committees other than the Audit Committee.

Assessments

The Board regularly monitors the adequacy of information given to directors, communication between the Board and management and the strategic direction and processes of the Board and its committees.

AUDIT COMMITTEE AND RELATIONSHIP WITH AUDITOR

The Company is relying upon the exemption in section 6.1 of National Instrument 52-110 Audit Committees ("NI 52-110"), which states that venture issuers are exempt from the requirements in Part 3 of NI 52-110 and the reporting obligations in Part 5 of NI 52-110. National Instrument 52-110 requires the Company, as a venture issuer, to disclose annually in its Information Circular certain information concerning the constitution of its Audit Committee and its relationship with its independent auditor, as set forth in the following.

Audit Committee

The Audit Committee reviews all financial statements of the Company prior to their publication, oversees audits, considers the adequacy of audit procedures, recommends the appointment of independent auditors, reviews and approves the professional services to be rendered by them and reviews fees for audit services. The Audit Committee Charter (the "Audit Charter") has set criteria for membership, which all members of the Audit Committee are required to meet consistent with NI 52-110 and other applicable regulatory requirements. The Audit Committee, as needed, meets separately (with the Company's auditors to discuss the various aspects of the Company's financial statements. A copy of the Audit Charter is attached to this Information Circular as Schedule "A".

Composition of Audit Committee

The members of the Audit Committee are Joseph Cullen, Alex Bugden and Timothy Ko. Mr. Bugden and Mr. Ko are "independent" in that they were independent and free from any interest and any business or other relationship, other than interests and relationships arising from shareholdings, which could or could reasonably be perceived to, materially interfere with their ability to act in the best interests of the Company. Mr. Cullen is an executive officer of the Company and therefore would not be considered independent. All of the members of the Audit Committee are financially literate.

Relevant Education and Experience of Audit Committee

Joseph Cullen - Mr. Cullen has over 7 years of public market experience primarily focused on the resource and technology sectors with an emphasis on investor relations and corporate finance. Mr. Cullen has a Business degree from Swansea University and a Postgrad in Economics from University College Cork. Mr. Cullen has become familiar with public company financial statements and the accounting principles used in reading and preparing financial statements.


Alex Bugden - Mr. Bugden is CEO, President, and Qualified Person for Sorrento Resources Ltd., a publicly traded company which focuses on mineral exploration. He is also the director and owner of Bugden Exploration Inc., a company which specializes in project management. In addition, he holds a BSc. (Hons.) degree in science and is a registered professional geologist.

Timothy Ko – Mr. Ko is President, CEO and a Director of Entheon Biomedical Corp., of which he also is an Audit Committee member. Mr. Ko has a broad background of leading private ventures in the service sector, investor relations, retail and technology. Most recently from 2017 to 2019 he served as director of Hyperbridge Technology, a company focused on the development of decentralized technologies that facilitate crowdfunding. Previous to that, Mr. Ko served as President of Acom Building Maintenance.

As a result of their education and experience, each member of the Audit Committee has familiarity with, an understanding of, or experience in:

(a) the accounting principles used by the Company to prepare its financial statements, and the ability to assess the general application of those principles in connection with estimates, accruals and reserves;
(b) reviewing or evaluating financial statements, that present a breadth and level of complexity of accounting issues that are generally comparable to the breadth and complexity of issues that can reasonably be expected to be raised by the Company's financial statements, and
(c) an understanding of internal controls and procedures for financial reporting.

Audit Committee Oversight

Since the commencement of the Company's most recently completed financial year, the Company's Board has not failed to adopt a recommendation of the Audit Committee to nominate or compensate an external auditor.

Reliance on Certain Exemptions

Since the effective date of NI 52-110, the Company has not relied on the exemptions contained in section 2.4 or section 8 of NI 52-110. Section 2.4 provides an exemption from the requirement that the Audit Committee must pre-approve all non-audit services to be provided by the auditor, where the total amount of fees related to the non-audit services are not expected to exceed 5% of the total fees payable to the auditor in the financial year in which the non-audit services were provided. Section 8 permits a company to apply to a securities regulatory authority for an exemption from the requirements of NI 52-110, in whole or in part.

Pre-approval of Policies and Procedures

The Audit Committee has not adopted specific policies and procedures for the engagement of non-audit services. Subject to the requirements of NI 52-110, the engagement of non-audit services is considered by the Company's Board, and where applicable the Audit Committee, on a case-by-case basis.


External Auditor Service Fees (By Category)

(2) Audit Committee Member.

The terms of office of those nominees who are presently directors will expire as of the date of the Meeting. All of the directors who are elected at the Meeting will have their term of office expire at the next annual general meeting of the Company.

Pursuant to the advance notice provisions the Company, as set out in the Articles of the Company, any additional director nominations for the Meeting must be received by the Company on or before November 10, 2025, being a date not less than 30 and no more than 65 days prior to the date of the Meeting. As of the date hereof, there were no nominations received.

To the knowledge of the Company, except as disclosed below, no proposed director of the Company is, or within the 10 years before the date of this Information Circular has been, a director or executive officer of any company that, while that person was acting in that capacity:

(a) was the subject of a cease trade or similar order or an order that denied the company access to any exemption under securities legislation, for a period of more than 30 consecutive days;
(b) was subject to an event that resulted, after the director or executive officer ceased to be a director or executive officer, in the company being the subject of a cease trade or similar order or an order that denied the relevant company access to any exemption under securities legislation, for a period of more than 30 consecutive days; or
(c) within a year of that person ceasing to act in that capacity, became bankrupt, made a proposal under any legislation relating to bankruptcy or insolvency or was subject to or instituted any proceedings, arrangement or compromise with creditors, or had a receiver, receiver manager or trustee appointed to hold its assets.

To the knowledge of the Company, no proposed director of the Company has, within the 10 years before the date of this Information Circular, become bankrupt, made a proposal under any legislation relating to bankruptcy or insolvency, or become subject to or instituted any proceedings, arrangement or compromise with creditors, or had a receiver, receiver manager or trustee appointed to hold the assets of the proposed director.

Directorships

As previously disclosed, several directors of the Company also serve as directors of one or more other resource companies involved in mineral exploration and/or development. It may occur from time to time that, as a consequence of his activities in the mineral industry and serving on such other boards, a director may become aware of potential resource property opportunities which are of interest to more than one of the companies on whose boards that person serves. Furthermore, it is possible that the directors of the Company and the directors of one or more such other companies (many of which are described herein) may also agree to allow joint participation on the Company's properties or the properties of that other company. Accordingly, situations may arise in the ordinary course, which involve a director in an actual or potential conflict of interest as well as issues in connection with the general obligation of a director to make corporate opportunities available to the


company whose board the director serves. In all such events, any director is required to disclose a financial interest in a contract or transaction by virtue of office, employment or security holdings or other such interest in another company or in a property interest under consideration by the Board, and is obliged to abstain from voting as a director of the Company in respect of any transaction involving that other company or in respect of any property in which an interest is held by him or her. The directors will use their best business judgment to avoid situations where conflicts or corporate opportunity issues might arise, and they must at all times fulfill their duties to act honestly and in the best interests of the Company as required by law.

Appointment of Auditor

Baker Tilly WM LLP, Chartered Professional Accountants, are the auditors of the Company and management proposes the re-appointment of the auditors for the ensuing year.

In the absence of instructions to the contrary the shares represented by proxy will be voted in favour of a resolution to appoint Baker Tilly WM LLP, Chartered Professional Accountants, as auditors of the Company for the ensuing year, at a remuneration to be fixed by the Board, unless the shareholder has specified in the shareholder's proxy that the shareholder's Shares are to be withheld from voting on the appointment of auditors.

OTHER MATTERS TO BE ACTED UPON

The Company will consider and transact such other business as may properly come before the Meeting or any adjournment thereof. The management of the Company knows of no other matters to come before the Meeting other than those referred to in the Notice. Should any other matters properly come before the Meeting, the shares represented by the Proxies solicited hereby will be voted on such matter in accordance with the best judgment of the persons voting by Proxy.

  1. Procedure For Reporting Of Fraud Or Control Weaknesses

Each employee is expected to report situations in which he or she suspects fraud or is aware of any internal control weaknesses. An employee should treat suspected fraud seriously, and ensure that the situation is brought to the attention of the Committee. In addition, weaknesses in the internal control procedures of the Company that may result in errors or omissions in financial


information, or that create a risk of potential fraud or loss of the Company's assets, should be brought to the attention of both management and the Committee.

To facilitate the reporting of suspected fraud, it is the policy of Company that the employee (the "whistleblower") has anonymous and direct access to the Chair of the Audit Committee. Should a new Chair be appointed prior to the updating of this document, current Chair will ensure that the whistleblower is able to reach the new Chair in a timely manner. In the event that the Chair of the Audit Committee cannot be reached, the whistleblower should contact the Chair of the Board of Directors. Access to the names and place of employment of the Company's Directors can be found in the Company's website.

In addition, it is the policy of the Company that employees concerned about reporting internal control weaknesses directly to management are able to report such weaknesses to the Committee anonymously. In this case, the employee should follow the same procedure detailed above for reporting suspected fraud.

11. Hiring Policies

The Committee is responsible for reviewing and approving the Company's hiring policies regarding partners, employees and former partners and employees of the present and former auditor of the Company.
