Meeting materials (the " Meeting Materials "), including the notice of meeting and management information circular, will be mailed to Shareholders and are available on World Copper's SEDAR+ profile at www.sedarplus.ca . Shareholders are urged to carefully review all Meeting Materials as they contain important information concerning the Arrangement, the transactions contemplated in connection therewith and the rights and entitlements of Shareholders in relation thereto. As described in the Meeting Materials, in additional to annual shareholder matters Shareholders will be asked at the Meeting to approve: (i) the Arrangement; and (ii) the consolidation of World Copper's issued and outstanding common shares on the basis of twenty (20) pre-consolidation common shares for one (1) post-consolidation common share (the " Consolidation ").

Arrangement Agreement Amendment The Company has entered into an amending agreement dated May 20, 2026 to the arrangement agreement dated May 14, 2026 (as amended, the " Arrangement Agreement ") with Spinco which provides that the completion of the Consolidation will be a condition precedent to the completion of the Arrangement. If the Consolidation is approved at the Meeting and subsequently becomes effective, the number of issued and outstanding common shares of World Copper will be reduced from approximately 262,931,067 common shares to approximately 13,146,553 post-Consolidation common shares, with any fractional shares resulting from the Consolidation rounded down to the nearest whole number, and the Company expects that a new CUSIP/ISIN number for the post-Consolidation common shares will be obtained. Details regarding the effective date of the Consolidation and the new CUSIP/ISIN number will be provided in a future news release once available and after consultation with the Company's transfer agent regarding the timing of the Consolidation and Arrangement becoming effective.

The Company is undertaking the Consolidation as it believes doing so may make the Company's common shares more attractive to a broader range of investors, improve trading liquidity and enhance the Company's ability to raise capital on more favourable terms. The Company's name will not be changed in conjunction with the Consolidation. Completion of the Arrangement and the Consolidation remains subject to customary conditions, including, among other things, (i) final approval of the TSXV; (ii) approval by Shareholders at the Meeting; and (iii) approval of the Arrangement by the Supreme Court of British Columbia.
