Dear Sirs and Mesdames:

We have acted as counsel to the Company in the Province of British Columbia in connection with the preparation of the registration statement on Form S-8 (the “Registration Statement”) under the U.S. Securities Act of 1933, as amended (the “Securities Act”) filed with the U.S. Securities and Exchange Commission on or about January 9, 2026. The Registration Statement registers 2,000,000 common shares of the Company (the “Plan Shares”), issuable under The 2025 Stock and Incentive Plan (the “Plan”) adopted by the Company.

The opinions expressed herein relate only to the laws of the Province of British Columbia and the federal laws of Canada applicable therein, and we express no opinion as to any laws other than the laws of the Province of British Columbia and the federal laws of Canada applicable therein as such laws exist and are construed as of the date hereof (the “Effective Date”). Our opinion does not take into account any proposed rules or legislative changes that may come into force following the Effective Date and we disclaim any obligation or undertaking to update our opinion or advise any person of any change in law or fact that may come to our attention after the Effective Date.

In rendering the opinion set forth below, we have reviewed (a) the Registration Statement; (b) the Company’s Articles of Incorporation; (c) the Company’s Notice of Articles; (d) the Plan; (e) certain records of the Company’s corporate proceedings as reflected in its minute books; and (f) such statutes, records, agreements, certificates and other documents as we have deemed relevant. In our examination, we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity with the originals of all documents submitted to us as copies thereof, and the truthfulness of the statements and representations contained therein. In addition, we have made such other examinations of law and fact as we have deemed relevant in order to form a basis for the opinion hereinafter expressed.

Based upon the foregoing, we are of the opinion that the Plan Shares, when issued pursuant to the terms of the Plan, and assuming the Company receives full payment therefor, will be validly issued, fully paid and non-assessable.
