For the Annual General and Special Meeting
to be held on Wednesday, December 17, 2025

The date of this Information Circular is November 10, 2025. This Information Circular accompanies the Notice of Annual General and Special Meeting (the “Notice”) and is furnished to shareholders (each, a “Shareholder”) holding common shares (each, a “Share”) in the capital of Selkirk Copper Mines Inc. (the “Company”) in connection with the solicitation by the management of the Company of proxies to be voted at the Annual General and Special Meeting (the “Meeting”) of the Shareholders to be held at 10:00 a.m. (Vancouver time) on Wednesday, December 17, 2025 at the Northern Spirit Room at the Hyatt Hotel, 511 Main Street, Whitehorse, YT, Y1A 2B8, or at any adjournment or postponement thereof. The solicitation will be primarily by mail, however, proxies may be solicited personally or by telephone by the regular officers and employees of the Company. The cost of solicitation will be borne by the Company.

APPOINTMENT AND REVOCATION OF PROXIES

The persons named in the accompanying form of Proxy are Directors and/or Officers of the Company. A SHAREHOLDER HAS THE RIGHT TO APPOINT A PERSON (WHO NEED NOT BE A SHAREHOLDER) TO ATTEND AND ACT FOR HIM ON HIS BEHALF AT THE MEETING OTHER THAN THE PERSONS NAMED IN THE ENCLOSED INSTRUMENT OF PROXY. TO EXERCISE THIS RIGHT, A SHAREHOLDER SHALL STRIKE OUT THE NAMES OF THE PERSONS NAMED IN THE INSTRUMENT OF PROXY AND INSERT THE NAME OF HIS/HER NOMINEE IN THE BLANK SPACE PROVIDED, OR COMPLETE ANOTHER INSTRUMENT OF PROXY. A PROXY WILL NOT BE VALID UNLESS IT IS DEPOSITED WITH THE COMPANY’S REGISTRAR AND TRANSFER AGENT, COMPUTERSHARE INVESTOR SERVICES INC., 100 UNIVERSITY AVENUE, 8TH FLOOR, TORONTO, ONTARIO, M5J 2Y1, OR BY TOLL FREE FAX 1.866.249.7775 WITHIN NORTH AMERICA, AND OUTSIDE NORTH AMERICA AT (416) 263-9524. PROXIES MUST BE RECEIVED NOT LESS THAN 48 HOURS (EXCLUDING SATURDAYS, SUNDAYS AND HOLIDAYS) BEFORE THE TIME OF THE MEETING OR ADJOURNMENT THEREOF, OR IF THE MEETING IS ADJOURNED OR POSTPONED, NO LATER THAN 48 HOURS PRECEDING THE TIME OF SUCH ADJOURNED OR POSTPONED MEETING (EXCLUDING SATURDAYS, SUNDAYS AND CIVIC HOLIDAYS IN THE CITY OF VANCOUVER, BRITISH COLUMBIA). LATE PROXIES MAY BE ACCEPTED OR REJECTED BY THE CHAIRMAN OF THE MEETING AT HIS DISCRETION, AND THE CHAIRMAN IS UNDER NO OBLIGATION TO ACCEPT OR REJECT ANY PARTICULAR LATE PROXY.

The Instrument of Proxy must be signed by the Shareholder or by his attorney in writing, or, if the Shareholder is a corporation, it must either be under its common seal or signed by a duly authorized officer.

A Shareholder who has given a proxy may revoke it at any time before it is exercised. In addition to revocation in any other manner permitted by law, a proxy may be revoked by instrument in writing executed by the Shareholder or by his attorney authorized in writing, or, if the Shareholder is a corporation, it must either be under its common seal, or signed by a duly authorized officer and deposited at the Company’s Registrar and Transfer Agent, Computershare Investor Services Inc., 100 University Avenue, 8th Floor, Toronto, Ontario, M5J 2Y1, at any time up to and including the last business day preceding the day of the Meeting, or any adjournment of it, at which the proxy is to be used, or to the Chairperson of the Meeting on the day of the Meeting or any adjournment of it. A revocation of a proxy does not affect any matter on which a vote has been taken prior to the revocation.

VOTING OF SHARES AND EXERCISE OF DISCRETION OF PROXIES

On any poll, the persons named in the enclosed Instrument of Proxy will vote the shares in respect of which they are appointed. Where directions are given by the Shareholder in respect of voting for or against any resolution, the proxy holder will do so in accordance with such direction.

IN THE ABSENCE OF ANY INSTRUCTION IN THE PROXY, IT IS INTENDED THAT SUCH SHARES WILL BE VOTED IN FAVOUR OF THE MOTIONS PROPOSED TO BE MADE AT THE MEETING AS STATED UNDER THE HEADINGS IN THIS INFORMATION CIRCULAR. The Instrument of Proxy enclosed, when properly signed, confers discretionary authority with respect to amendments or variations to the matters which may properly be brought before the Meeting. At the time of printing this Information Circular, the Management of the Company is not aware that any such

---

amendments, variations or other matters are to be presented for action at the Meeting. However, if any other matters which are not now known to the Management should properly come before the Meeting, the Proxies hereby solicited will be exercised on such matters in accordance with the best judgment of the nominee.

In order to approve a motion proposed at the Meeting, a majority of greater than 50% of the votes cast will be required (an "Ordinary Resolution") unless the motion requires a Special Resolution, in which case a majority of not less than two thirds of the votes cast will be required. In the event a motion proposed at the Meeting requires disinterested Shareholder approval, common shares held by Shareholders of the Company who are also "insiders", as such term is defined under applicable securities laws, will be excluded from the count of votes cast on such motion.

Voting by Registered Shareholders

If you are a Registered Shareholder you may wish to vote by proxy whether or not you are able to attend the Meeting in person. Registered Shareholders electing to submit a proxy may do so by completing, dating and signing the enclosed form of proxy and returning it to the Company's transfer agent, Computershare Investor Services Inc. (the "Transfer Agent"), Proxy Department, 8th Floor, 100 University Avenue, Toronto, Ontario, M5J 2Y1, in accordance with the instructions on the Proxy.

You may also vote by telephone or via the Internet. To vote by telephone, in Canada and the United States only, call 1-866-732-8683 from a touch tone phone. When prompted, enter your Control Number listed on the proxy and follow the voting instructions. To vote via the Internet, go to www.investorvote.com and enter your Control Number listed on the proxy and follow the voting instructions on the screen.

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

Advice To Beneficial Shareholders

The information set forth in this section is of significant importance to many Shareholders as a substantial number of Shareholders do not hold common shares in their own name. Shareholders who do not hold their common shares in their own name (referred to in this information circular as "Beneficial Shareholders") should note that only proxies deposited by Shareholders whose names appear on the records of the Company as the registered holders of common shares can be recognized and acted upon at the Meeting. If common shares are listed in an account statement provided to a Shareholder by a broker, then, in almost all cases, those common shares will not be registered in the Shareholder's name on the records of the Company. Such common 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 common shares are registered under the name CDS & Co. (the registration name for The Canadian Depositary for Securities, which acts as nominee for many Canadian brokerage firms). The common shares held by brokers or their agents or nominees can only be voted (for or against resolutions) upon the instructions of the Beneficial Shareholder. Without specific instructions, a broker and its agents are prohibited from voting shares for the broker's clients. Therefore, Beneficial Shareholders should ensure that instructions respecting the voting of their common shares are communicated to the appropriate person.

Applicable regulatory rules require intermediaries/brokers to seek voting instructions from Beneficial Shareholders in advance of Shareholders' meetings. Every intermediary/broker has its own mailing procedures and provides its own return instructions to clients, which should be carefully followed by Beneficial Shareholders in order to ensure that their shares are voted at the Meeting. The purpose of the form of proxy or voting instruction form provided to a Beneficial Shareholder by its broker, agent or nominee is limited to instructing the registered holder of the common shares on how to vote such shares on behalf of the Beneficial Shareholder. The majority of brokers now delegate responsibility for obtaining instructions from clients to Broadridge Investor Communications ("Broadridge"). Broadridge typically supplies a voting instruction form, mails those forms to Beneficial Shareholders and asks those Beneficial Shareholders to return the forms to Broadridge or follow specific telephone or other voting procedures. Broadridge then tabulates the results of all instructions received by it and provides appropriate instructions respecting the voting of the shares to be represented at the Meeting. A Beneficial Shareholder receiving a voting instruction form from Broadridge cannot use that form to vote common shares directly at the Meeting. Instead, the voting instruction form must be returned to Broadridge or the alternate voting procedures must be completed well in advance of the Meeting in order to ensure such common shares are voted.

Although Beneficial Shareholders may not be recognized directly at the Meeting for the purpose of voting common shares registered in the name of their broker, agent or nominee, a Beneficial Shareholder may attend the Meeting as a proxyholder for a shareholder and vote common shares in that capacity. Beneficial Shareholders who wish to attend the Meeting and

• 3 -

indirectly vote their common shares as proxyholder for the registered shareholder should contact their broker, agent or nominee well in advance of the Meeting to determine the steps necessary to permit them to indirectly vote their common shares as a proxyholder.

The Company will not pay for an intermediary to deliver proxy related materials and voting instruction forms to objecting beneficial owners (called OBOs for Objecting Beneficial Owners). OBOs have objected to their intermediary disclosing ownership information about themselves to the Company. Accordingly, OBOs will not receive the materials unless their intermediary assumes the costs of delivery.

The Company is not relying on the “notice-and-access” delivery procedures outlined in National Instrument 54-101 to distribute copies of the proxy related materials in connection with the Meeting.

Financial Statements

The audited financial statements of the Company for the financial years ended March 31, 2025 and March 31, 2024 (the “Financial Statements”), together with the Auditor’s Report thereon, will be presented to Shareholders at the Meeting. The Financial Statements, the Auditor’s Report thereon together with related Management’s Discussion and Analysis for the financial years ended March 31, 2025 and March 31, 2024 are available on SEDAR+ at www.sedarplus.ca. The Notice of Annual General and Special Meeting of Shareholders, Information Circular, Request for Financial Statements and form of Proxy will be available from the Company’s Registrar and Transfer Agent, Computershare Investor Services Inc., 100 University Avenue, 8th Floor, Toronto, Ontario, M5J 2Y1, or from the Company’s head office located at Suite 3123, 595 Burrard Street, PO Box 49139, Bentall Three, Vancouver, British Columbia, V7X 1J1.

Request For Financial Statements

National Instrument 51-102 “Continuous Disclosure Obligations” sets out the procedures for a shareholder to receive financial statements. If you wish to receive financial statements, you may use the enclosed form or provide instructions in any other written format. Registered shareholders must also provide written instructions in order to receive the Financial Statements.

Quorum

Under the Company’s Articles, the quorum for the transaction of business at the Meeting consists of two (2) persons who are, or who represent by proxy, shareholders who, in the aggregate, hold at least 5% of the issued shares entitled to be voted at the Meeting.

VOTING SHARES AND PRINCIPAL SHAREHOLDERS

The authorized capital of the Company consists of an unlimited number of common shares (“Shares”) without par value, and an unlimited number of preferred shares without par value. As of the date of this Circular, there were 126,380,911 Shares issued and outstanding. Each Share held as of the Record Date is entitled to one vote. The Shares are listed for trading on the TSX Venture Exchange (“TSX-V”) under the symbol “SCMI”.

To the knowledge of the directors and executive officers of the Company, as at the date of the Information Circular, there are no beneficial owners or persons exercising control or direction over the Company carrying more than 10% of the outstanding voting rights other than:

Name of Shareholder	Number of Shares	Percentage of Issued and Outstanding Shares
The Selkirk First Nation	28,123,374(1)	22.25%

Note:

(1) The Common Shares are held by 843094 Yukon Inc., an entity wholly owned by The Selkirk First Nation.

(2) In addition to these Common Shares, The Selkirk First Nation also beneficially owns or controls, directly or indirectly 1,562,500 warrants to purchase Common Shares. Assuming the conversion of these warrants, The Selkirk First Nation would beneficially own or control, directly or indirectly 23.20% of the Common Shares on a partially diluted basis.

The term of office of each of the present directors expires at the Meeting. The persons named below will be presented for election at the Meeting as management’s nominees. Management does not contemplate that any of these nominees will be unable to serve as a director.

Corporate Cease Trade Orders or Bankruptcies

To the best of management's knowledge, no proposed director of the Company is, or within the ten (10) years before the date of this Information Circular has been, a director, chief executive officer or chief financial officer of any company that:

(a) was subject to a cease trade order, an order similar to a cease trade order, or an order that denied the relevant company access to any exemption under securities legislation, that was in effect for a period of more than 30 consecutive days that was issued while the proposed director was acting in the capacity as director, chief executive officer or chief financial officer; or
(b) was subject to a cease trade order, an order similar to a cease trade order, or an order that denied the

---

relevant company access to any exemption under securities legislation, that was in effect for a period of more than 30 consecutive days that was issued after the proposed director ceased to be a director, chief executive officer or chief financial officer and which resulted from an event that occurred while that person was acting in the capacity as director, chief executive officer or chief financial officer.

To the best of management's knowledge, no proposed director of the Company is, or within ten (10) years before the date of this Information Circular, has been, a director or an executive officer of any company that, while the person was acting in that capacity, or within a year of that person ceasing to act in the 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 or made a proposal under any legislation relating to bankruptcies or insolvency.

Penalties and Sanctions

To the best of management's knowledge, no proposed director of the Company has been subject to, after March 31, 2016: (a) any penalties or sanctions imposed by a court relating to securities legislation or by a securities regulatory authority or has entered into a settlement agreement with securities regulatory authority; or (b) any other penalties or sanctions imposed by a court or regulatory body that would likely be considered important to a reasonable security holder in deciding whether to vote for a proposed director, other than as follows:

Mr. Morrison was a director of Detour Gold from May 2010 to December 2018. On May 13, 2014, a proposed securities class action claiming, among other things, special and general damages in the amount of $80 million, was commenced against Detour Gold Corporation ("Detour Gold") and its former President and Chief Executive Officer in relation to the Detour Gold's secondary market public disclosure concerning the Detour Lake Mine operations between April 9, 2013 and November 7, 2013 (the "Class Action Claim"). On July 10, 2014, the plaintiff issued a fresh as amended statement of claim incorporating allegations respecting the Detour Gold's primary market disclosure, specifically in respect of its final short form prospectus dated June 2, 2013. On November 29, 2016, the parties agreed to settle the claim for $6 million and dismiss the action without any admission of liability subject to court approval, which was subsequently obtained on June 27, 2017.

Mr. McLeod, as a result of failing to provide a Practice Review Questionnaire, entered into a consent order with Engineers and Geoscientists BC (APEGBC - Association of Professional Engineers and Geoscientists of the Province of British Columbia) dated June 9, 2022 (the "Consent Order") that resulted in Mr. McLeod registration as a P.Geo. being cancelled. A copy of the Consent Order is publicly available on the Engineers and Geoscientists BC website.

4. Appointment of Auditor and Remuneration of Auditor

At the Meeting, Shareholders will be asked to pass an ordinary resolution to appoint Deloitte LLP as auditors of the Company and to authorize the Board to fix the remuneration to be paid to Deloitte LLP. An ordinary resolution needs to be passed by a simple majority of the votes cast by the Shareholders present in person or represented by proxy and entitled to vote at the Meeting. Deloitte LLP have been the Company's auditors since August 19, 2025.

Management recommends that Shareholders vote FOR the appointment of Deloitte LLP as the Company's auditors, and the authorizing the Board to fix the remuneration paid to the auditors.

5. Re-Approval of Stock Option Plan

The Company has in place a Stock Option Plan which was approved by the Company's shareholders at the Company's annual general meeting held on November 28, 2024, pursuant to which its directors, officers, employees, consultants and eligible charitable organizations may be granted options to acquire common shares of the Company. A maximum of 10% of the issued common shares of the Company, from time to time, may be reserved for issuance pursuant to the exercise of options.

Under the policies of the Exchange, a rolling stock option plan, such as the Company's, must be approved by Shareholders on a yearly basis.

Accordingly, at the Meeting, Shareholders will be asked to pass an Ordinary Resolution re-approving the Company's Stock Option Plan. A summary of the material provisions of the Stock Option Plan are as follows:

Unless contrary instructions are indicated on the instrument of proxy or the voting information form, the Management Proxyholders intend to vote FOR the Stock Option Plan Resolution.

6. Alteration of Company’s Articles to Allow Directors to Determine Shareholder Meeting Locations

Following the Company’s acquisition of a 100% interest in the former Minto copper-gold-silver mine in the Yukon from Selkirk First Nation affiliates, the Board determined that it would be appropriate and in the best interests of the Company to be able to hold shareholder meetings at locations outside of British Columbia, which would include the ability for the Company to hold shareholder meetings in the Yukon.

Under the Business Corporations Act, a company must hold its general meeting in British Columbia, or may hold its general meeting at a location outside British Columbia if: (i) the location is provided for in the articles, (ii) the articles do not restrict the company from approving a location outside of British Columbia for the holding of the general meeting and the location for the meeting is (A) approved by the resolution required by the articles for that purpose, or (B) if no resolution is required for that purpose by the articles, approved by ordinary resolution, or (iii) the location for the meeting is approved in writing by the registrar before the meeting is held.

The Board has determined that it would be appropriate and in the best interests of the Company to alter its Articles to provide the directors with the ability to determine the time and place of shareholder meetings.

In order to implement the proposed alteration to the Articles, the shareholders of the Company will be asked to consider and, if thought fit, pass an ordinary resolution, with or without variation, to alter the Company's current Articles, the text of which is set out on Schedule “B” attached hereto.

A complete copy of the Company's articles, as amended, may be inspected at the head office of the Company, at #3123 – 595 Burrard Street, Vancouver, British Columbia, V7X 1J1 during normal business hours and at the Meeting. In addition, a complete copy of the proposed Articles, as amended, will be mailed, free of charge, to any holder of Common Shares who requests a copy, in writing, from the Corporate Secretary of the Company. Any such requests should be mailed to the Company, at its head office, to the attention of the Corporate Secretary.

Approval of the foregoing resolution requires the approval of the shareholders of the Company by ordinary resolution, being a majority of the votes cast by shareholders at the Meeting.

Unless contrary instructions are indicated on the instrument of proxy or the voting information form, the Management Proxyholders intend to vote FOR the Alteration of the Company’s Articles.

7. Other Business

While management of the Company is not aware of any business other than that mentioned in the Notice of Meeting to be brought before the Meeting for action by the shareholders, it is intended that the proxies hereby solicited will be exercised upon any other matter or proposal that may properly come before the Meeting, or any adjournments thereof, in accordance with the discretion of the persons authorized to act thereunder.

Compensation Discussion and Analysis

In accordance with the provisions of applicable securities legislation, the Company had two (2) "Named Executive Officers" during the financial years ended March 31, 2025 and March 31, 2024, namely Marilyn Miller, CFO, and Alan MacDonald, CEO. Ms. Miller was appointed as CFO on August 17, 2017 and Mr. MacDonald was appointed as CEO on August 17, 2017. Both Ms. Miller and Mr. MacDonald resigned from their respective positions effective July 31, 2025.

The Company's process for determining executive compensation is very simple. In particular, the Company relies solely on board discussion without any formal objectives, criteria and analysis.

Through its executive compensation practices, the Company seeks to provide value to its shareholders through a strong executive leadership. Specifically, the Company's executive compensation structure seeks to attract and retain talented and experienced executives necessary to achieve the Company's strategic objectives, motivate and reward executives whose knowledge, skills and performance are critical to the Company's success, and align the interests of the Company's executives and shareholders by motivating executives to increase Shareholder value.

The Company does not currently pay any base salary compensation to its NEOs for their services in their capacity as NEOs. Compensation to NEOs currently consists solely of the granting of stock options. In determining executive compensation,

12291537v2

---

the Company relies solely on the experience and knowledge of the Board of Directors of the Company (the "Board") in terms of appropriate compensation for executive officers with similar abilities and experience.

The Board has not conducted a formal evaluation of the implications of the risks associated with the Company's compensation policies. Risk management is a consideration of the Board when implementing its compensation policies and the Board does not believe that the Company's compensation policies result in unnecessary or inappropriate risk taking including risks that are likely to have a material adverse effect on the Company.

Stock Option Plans and Other Incentive Plans

The Company has in effect a stock option plan (the "Stock Option Plan") in order to provide effective incentives to directors, officers, and senior management personnel and consultants of the Company and to enable the Company to attract and retain experienced and qualified individuals in those positions by permitting such individuals to directly participate in an increase in per share value created for the Company's shareholders.

Use of Financial Instruments

The Company does not have a policy that would prohibit an NEO or director from purchasing financial instruments, including prepaid variable forward contracts, equity swaps, collars or units of exchange funds, that are designed to hedge or offset a decrease in market value of equity securities granted as compensation or held, directly or indirectly, by the NEO or director. However, management is not aware of any NEO or director purchasing such an instrument.

Narrative Discussion

The only plan-based award program that the Company currently operates is the Stock Option Plan. The purpose of the Stock Option Plan is to advance the interests of the Corporation, through the grant of options, by (1) providing an incentive mechanism to foster the interest of directors, officers, employees and consultants in the success of the Corporation; (2) encouraging directors, officers, employees and consultants to remain with the Corporation; and (3) attracting new directors, officers, employees and consultants.

The Stock Option Plan is administered by the Board or the Compensation Committee established by the Board for the purpose of administering the Stock Option Plan. At the present time, option grants are approved by either the Board or the Compensation Committee. It is the responsibility of the granting party to determine:

• persons entitled to receive the option grant;
• the number of options to be granted;
• the exercise price, which shall not be less than market price for the Company’s common shares at the date of grant;
• an expiry date of no more than ten (10) years after the date of the grant; and
• the manner, if any, in which the option shall vest and become exercisable.

No director of the Company who is not an NEO has received, during the most recently completed financial year, compensation pursuant to:

• any standard arrangement for the compensation of directors for their services in their capacity as directors, including any additional amounts payable for committee participation or special assignments;

Company’s directors have received any cash compensation for services provided in their capacity as directors during the Company’s most recently completed financial year.
