The Offer is made only for Shares and is not made for any Convertible Securities (including Options) or other rights to acquire Shares.

The Offer has been extended and now remains open for acceptance until 5:00 p.m. (Toronto Time) on February 10, 2026 (the “Expiry Time”), unless the Offer is further extended, accelerated or withdrawn by the Offeror in accordance with its terms. This extension constitutes the Mandatory Extension Period contemplated in the Offer and Circular.

To the extent specifically set out in this document, each of the Original Offer Documents is deemed to be amended by the First Notice of Variation, Change and Extension, the Second Notice of Variation, Change and Extension, the Third Notice of Variation, Change and Extension, and this Notice of Variation, Change and Extension (collectively, the “Notices”) to give effect to the amendments to the Original Offer and Circular described therein and herein. Unless the context otherwise requires, references in this document to the “Offer”, the “Circular” and the “Offer and Circular” mean the Original Offer, the Original Circular and the Original Offer and Circular, respectively, each as amended and varied by the Notices.

Registered Shareholders will not be required to pay any fee or commission if they accept the Offer by tendering their Shares directly with the Depositary.

Shareholders should consult such broker, nominee or other intermediary to determine whether any charges will apply.

Non-registered Shareholders whose Shares are held on their behalf, or for their account, by a broker, investment dealer, bank, trust company or other intermediary, should contact such intermediary directly if they wish to accept the Offer. Intermediaries may establish tendering cut-off times that are up to 48 hours prior to the Expiry Time. As a result, non-registered Shareholders wishing to tender their Shares should promptly and carefully follow the instructions provided to them by their broker, investment dealer, bank, trust company or other intermediary.

NOTICE TO SHAREHOLDERS IN THE UNITED STATES AND OTHER SHAREHOLDERS OUTSIDE CANADA

The Offer is being made for the securities of a Canadian company that does not have securities registered under section 12 of the United States Securities Exchange Act of 1934, as amended (the “U.S. Exchange Act”). Accordingly, the Offer is not subject to section 14(d) of the U.S. Exchange Act or Regulation 14D thereunder. In reliance on the cross-border exemption provided by rule 14d-1(c) (the “Tier 1 Exemption”), the Offer is exempt from Rules 14e-1 and 14e-2 of Regulation 14E. The Offer is made in the United States with respect to securities of a “foreign private issuer”, as such term is defined in Rule 3b-4 under the U.S. Exchange Act, in accordance with Canadian corporate and Securities Laws requirements. Shareholders in the United States should be aware that such requirements are different from those of the United States applicable to tender offers under the U.S. Exchange Act and the rules and regulations promulgated thereunder.

Because the consideration consists solely of Offeror Common Shares and, to the Offeror’s knowledge, U.S. holders hold 10% or less of the outstanding Shares, the Offer is being made in reliance on Rule 802 under the United States Securities Act of 1933. The Offeror has furnished, or will furnish, the Offer and Circular, including this Notice of Variation, Change and Extension (and any amendments or supplements) to the SEC on Form CB and has filed, or will file, a Form F-X appointing an agent for service of process in the United States. The Offer and Circular, including the First Notice of Variation, Change and Extension, the Second Notice of Variation, Change and Extension and this Notice of Variation, Change and Extension, is being provided to U.S. holders in English on a comparable basis to Canadian holders. If dissemination is by publication in Canada, the Offeror will concurrently publish in the United States in a manner reasonably calculated to inform U.S. holders.

The Offer is being made for the securities of a Canadian company by a Canadian company. The Offer is subject to disclosure requirements of a foreign country that are different from those of the United States. Financial statements included in this document, if any, have been prepared in accordance with foreign accounting standards that may not be comparable to the financial statements of United States companies. It may be difficult for you to enforce your rights and any claim you may have arising under the federal securities laws, since the Offeror and the Company are located in a foreign country, and some or all of their officers and directors may be residents of a foreign country. You may not be able to sue a foreign company or its officers or directors in a foreign court for violations of U.S. securities laws. It may be difficult to compel the Offeror or the Company and their affiliates to subject themselves to a U.S. court’s judgement. You should be aware that the Offeror may purchase securities otherwise than under the Offer, such as in open market or privately negotiated purchases, in accordance with applicable law.

In accordance with Canadian law and in reliance on Rule 14e-5(b)(10) under the U.S. Exchange Act, the Offeror and its affiliates may, from time to time during the pendency of the Offer, purchase or arrange to purchase Shares (or related securities) outside the Offer, provided that no such purchases will be made in the United States or by use of U.S. jurisdictional means. Any information about such purchases that is made public in Canada will also be made publicly available in the United States on a comparable basis, including by press release and by furnishing a Form CB to the SEC.

Shareholders in the United States should be aware that the disposition of their Shares (or the exercise, exchange or redemption of the Convertible Securities) and the acquisition of Offeror Common Shares by them as described herein may have tax consequences both in the United States and in Canada. Such consequences for Shareholders who are resident in, or citizens of, the United States may not be described fully herein and such Shareholders are encouraged to consult their tax advisors. See Section 18 of the Original Circular, “Certain Canadian Federal Income Tax Considerations”, and Section 19 of the Original Circular, “Certain United States Federal Income Tax Considerations”.

The enforcement by Shareholders of civil liabilities under U.S. federal securities Laws may be affected adversely by the fact that each of the Offeror and the Company is incorporated under the Laws of Canada, that some or all of their respective officers and directors may be residents of a foreign country, that some or all of the experts named herein may be residents of a foreign country and that all or a substantial portion of the assets of the Offeror and the Company and said Persons may be located outside the United States.

THE OFFEROR COMMON SHARES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SEC OR ANY U.S. STATE SECURITIES COMMISSION NOR HAS THE SEC OR ANY U.S. STATE SECURITIES COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY OF THE OFFER AND CIRCULAR. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

Shareholders should be aware that, during the period of the Offer, the Offeror or its affiliates, directly or indirectly, may bid for or make purchases of Offeror Common Shares or Shares, or certain related securities, as permitted by applicable Laws or regulations of the United States, Canada or its provinces or territories.

NOTICE TO HOLDERS OF CONVERTIBLE SECURITIES

The Offer is being made only for Shares and is not being made for any Convertible Securities (including Options) or other rights to acquire Shares. Holders of Convertible Securities who wish to accept the Offer with respect to the underlying Shares should, to the extent permitted by the terms of the Convertible Securities, applicable Laws and the Cease Trade Order, exercise the rights under such Convertible Securities to acquire Shares and tender the underlying Shares in accordance with the terms of the Offer. Any such exercise must be completed sufficiently in advance of the Expiry Time to ensure that Shares will be available for tender at or prior to the Expiry Time or in sufficient time to comply with the procedures described in Section 3 of the Offer, “Manner of Acceptance”, and Section 6 of the Original Circular, “Treatment of Convertible Securities”. The Partial Revocation Order does not provide for the acquisition of Shares upon the exercise of conversion rights under Convertible Securities.

The tax consequences to holders of Convertible Securities of exercising, exchanging or converting such securities are not described in either Section 18 of the Original Circular, “Certain Canadian Federal Income Tax Considerations” or in Section 19 of the Original Circular, “Certain United States Federal Income Tax Considerations”. Holders of Convertible Securities should consult their tax advisors for advice with respect to potential income tax consequences to them in connection with the decision as to whether to exercise, exchange or convert their Convertible Securities.

Certain statements contained in this Notice of Variation, Change and Extension, or incorporated by reference in the Offer and Circular constitute “forward-looking statements” and “forward- looking information” as defined under Securities Laws (collectively “forward-looking statements”).

Forward-looking statements and forward-looking information are not based on historical facts, but rather on current expectations and projections about future events and is therefore subject to risks and uncertainties that could cause actual results to differ materially from the future results expressed or implied by the forward-looking statements and forward-looking information.

This Notice of Variation, Change and Extension contains forward-looking statements including: those relating to the Louise Project, including statements with respect to the drill permit application, the timing of receiving the permit decision, and the Offeror’s plan to drill test the targets; and those relating to the Offer, including statements with respect to the anticipated timing, mechanics, completion and settlement of the Offer; the ability of the Offeror to complete the transactions contemplated by the Offer, including the termination of the Helix Farm-In Agreement; the reasons to participate in the Offer; whether Gold Basin will regain regulatory compliance; the purpose of the Offer; any commitment to acquire Shares; the value of the Offeror Common Shares received as consideration under the Offer; the Offeror’s objectives, strategies, intentions, expectations and guidance and future financial and operating performance and prospects; information concerning the Company and the Offeror (and their respective affiliates), including the revocation of the Cease Trade Order; the Offeror’s plans for the Company in the event the Offer is successful and the integration of the Offeror’s and the Company’s businesses and operations; the anticipated effect of the Offer and the expected benefits of tendering Shares to the Offer, both to the Offeror and to the Shareholders, such as the consolidation of a gold district in Mojave County, Arizona and other synergies that may result from the proposed combination between the Offeror and the Company; the satisfaction of the conditions to consummate the Offer and other statements that are not historical facts. It is important to know that:

With respect to forward-looking statements contained in this Notice of Variation, Change and Extension, the Offeror has made assumptions regarding, among other things: integrate the Offeror’s and the Company’s businesses and operations and realize financial, operational and other synergies from the Offer and a Compulsory Acquisition or Subsequent Acquisition Transaction; that each of the Offeror, the Company and, following the Offer and a Compulsory Acquisition or Subsequent Acquisition Transaction, the Offeror will have the ability to continue as a going concern and realize its assets and discharge its liabilities in the normal course of business; that the Helix Farm-In Agreement will be terminated; the Offeror’s ability to execute on its plans as described herein and in its other disclosure documents and the impact that the successful execution of such plans will have on the Offeror and, following the combination, the combined entity and the combined entities’ respective stakeholders; that the Company’s publicly available information, including its public reports and securities filings as of January 29, 2026 remain accurate in all material respects; that the current commodity price and foreign exchange environment will continue or improve; future exchange rates and interest rates; future debt levels; the value inherent in Gold Basin’s portfolio of projects, including the Gold Basin Project; the Offeror will receive the Regulatory Approvals and all other necessary consents on the timelines and in the manner currently anticipated; the advice received from professional advisors is accurate; there will be no material changes to government and environmental regulations adversely affecting the Offeror’s operations, other than as discussed in this section; and the impact of the current economic climate and financial, political and industry conditions on the Offeror’s operations, including its financial condition and asset value, will remain consistent with the Offeror’s current expectations as set out in this section.

All figures and descriptions provided in this Notice of Variation, Change and Extension related to the proposed transaction, including those around consideration, key metrics, reasons for the Offer, and the potential benefits to the Shareholders and the Offeror Shareholders (including increased shareholder returns and improved performance and administration savings), are based on and assume the following: (a) the Offeror’s and the Company’s liquidity, debt, debt costs and assets (including reserves), will not change from what was the case on January 29, 2026, in the case of the Offeror, and from what the Offeror has ascertained from the Company’s public filings on SEDAR+ up to and including October 20, 2025 and from the Company’s disclosures on its website at www.goldbasincorp.com up to and including January 8, 2026, in the case of the Company; (b) 135,130,486 Shares are issued and outstanding immediately prior to the date of the Offer (according to the latest information available on the website of the TSXV); (c) that all of the Shares are tendered to the Offer pursuant to the terms thereof; and (d) no other Shares or Offeror Common Shares are issued before the successful completion of the Offer.

Although the Offeror believes that the expectations reflected in the forward-looking statements contained in this Notice of Variation, Change and Extension, and the assumptions on which such forward-looking statements are made, are reasonable, there can be no assurance that such expectations will prove to be correct. The risks, uncertainties, contingencies and other factors that may cause actual results to differ materially from those expressed or implied by the forward-looking statements may include the following: the market value of the Offeror Common Shares received as consideration under the Offer and the impact of the issuance of Offeror Common Shares on the market price of the Offeror Common Shares; the inaccuracy of the Company’s public disclosure upon which the Offer is predicated; the failure to obtain the Regulatory Approvals and to satisfy the other conditions to the Offer on a timely basis; competitive responses to the announcement or completion of the Offer; as well as the risks discussed in Section 22 of the Original Circular, “Risk Factors” and in Section 1 of the Second Notice of Variation, Change and Extension, “Waiver of Minimum Tender Condition”. Should one or more risk, uncertainty, contingency or other factor materialize or should any factor or assumption prove incorrect, actual results could vary materially from those expressed or implied in the forward-looking statements. Accordingly, you should not place undue reliance on forward-looking statements. The Offeror does not assume any obligation to update or revise any forward-looking statements after the date of this Notice of Variation, Change and Extension or to explain any material difference between subsequent actual events and any forward-looking statements, except as required by applicable Securities Laws. Readers are cautioned that such assumptions, risks and uncertainties should not be construed as exhaustive.

The forward-looking statements contained in this Notice of Variation, Change and Extension speak only as of the date of this Notice of Variation, Change and Extension. Except as expressly required by applicable Securities Laws, we do not undertake any obligation to publicly update any forward-looking statements. The forward-looking statements contained in this Notice of Variation, Change and Extension are expressly qualified by this cautionary statement.

For a further discussion regarding the risks related to the Offer and the Offeror, see Section 22 of the Original Circular, “Risk Factors” and Section 1 of the Second Notice of Variation, Change and Extension, “Waiver of Minimum Tender Condition”, and the Offeror’s other public filings, available in Canada on SEDAR+ at www.sedarplus.com, and on the Offeror’s website at www.canexmetals.ca.

This Notice of Variation, Change and Extension amends, varies and supplements the information provided in the Original Offer and Circular, as amended by the First Notice of Variation, Change and Extension, the Second Notice of Variation, Change and Extension, and the Third Notice of Variation, Change and Extension, pursuant to which the Offeror is offering to purchase, on the terms and subject to the conditions of the Offer, all of the issued and outstanding Shares (including any Shares which may become issued and outstanding after the date of the Original Offer and prior to the Expiry Time).

As set out in this Notice of Variation, Change and Extension, the Offeror has (a) extended the Expiry Time of the Offer to 5:00 p.m. (Toronto Time) on February 10, 2026; and (b) provided additional disclosure, including, but not limited to, (i) the satisfaction or waiver all of the conditions to Offer, including the Statutory Minimum Condition, as of 5:00 p.m. (Toronto time) on January 29, 2026 (being the expiry time of the initial deposit period), (ii) the direction to the Depositary to take up and pay for all Shares that were validly deposited and not withdrawn under the Offer as of the expiry time of the initial deposit period, and (iii) the variation of the Partial Revocation Order to extend the expiry date of the Partial Revocation Order. Consequential amendments in accordance with this Notice of Variation, Change and Extension are deemed to be made, where required, to the Original Offer Documents, as amended by the First Notice of Variation, Change and Extension, the Second Notice of Variation, Change and Extension, and the Third Notice of Variation, Change and Extension. Except as otherwise set out in this Notice of Variation, Change and Extension, the terms and conditions set out in the Original Offer Documents, as amended by the First Notice of Variation, Change and Extension, the Second Notice of Variation, Change and Extension, and the Third Notice of Variation, Change and Extension, continue to remain in effect, unamended. This Notice of Variation, Change and Extension should be read in conjunction with the Original Offer Documents, as amended by the First Notice of Variation, Change and Extension, the Second Notice of Variation, Change and Extension, and the Third Notice of Variation, Change and Extension.

By written notice to the Depositary dated January 29, 2026, the Offeror (a) irrevocably waived (prior to the expiry of the initial deposit period) all remaining unsatisfied conditions set out in Section 4 of the Original Offer, “Conditions of the Offer”; (b) confirmed that all of the conditions set forth in Section 4 of the Original Offer, “Conditions of the Offer”, including the Statutory Minimum Condition, have been satisfied or waived as of 5:00 p.m. (Toronto time) on January 29, 2026 (being the expiry time of the initial deposit period), and (c) directed the Depositary to take up all Shares that were validly deposited and not withdrawn under the Offer. See Section 7 of this Notice of Variation, Change and Extension, “Take Up and Payment for Deposited Shares”.

The Offeror has extended the Expiry Time of the Offer from 5:00 p.m. (Toronto Time) on January 29, 2026 to 5:00 p.m. (Toronto Time) on February 10, 2026.

The Offeror continues to believe that the Offer provides a number of compelling benefits for Shareholders that Gold Basin cannot achieve on a standalone basis, including:

MAP: Mineral land positions of CANEX’s Gold Range Project (Red) and Gold Basin’s Gold Basin Project (Blue) are adjacent.

The Offer represents an opportunity for Shareholders to embrace a combined entity with more focused management, greater financial strength, a well-positioned portfolio of mineral projects and far superior governance and regulatory compliance.

The disclosure contained in Section 25 of the Original Circular, “Cease Trade Order and Partial Revocation Order”, is hereby updated to provide the following additional information:

On January 28, 2026, a variation order was issued by the Commission, varying the Partial Revocation Order such that the Partial Revocation Order will expire on March 31, 2026; provided, however, that if more than 50% of the Shares have been tendered to the Offer and taken up and paid for by the Offeror on or prior to March 31, 2026, the Partial Revocation Order will expire on June 30, 2026 in respect of a Compulsory Acquisition or Second Step Transaction undertaken by the Offeror to facilitate the acquisition by the Offeror of 100% of the issued and outstanding Shares.
