Mineros launches normal course issuer bid

Mineros S.A. (TSX: MSA, OTCQX: MNSAF, BVC: MINEROS) (“ Mineros ” or the “ Company ”) announces that has received acceptance from the Toronto Stock Exchange (the “ TSX ”) of the Company’s notice of intention to make a normal course issuer bid (the “ NCIB ”). Shareholders approved resolutions relating to the NCIB at the extraordinary meeting of shareholders held on July 14, 2026. Mineros’ board of directors believes that the NCIB represents an appropriate and desirable use of its available liquidity to increase shareholder value and is in the best interests of Mineros and its shareholders.

Under the NCIB, the Company may purchase, at its discretion and in accordance with applicable regulatory requirements, during the period commencing on July 17, 2026, and ending on the earlier of (i) July 16, 2027, and (ii) the date on which the Company has purchased 14,639,683 common shares, representing 5% of the 292,793,666 common shares issued and outstanding on the date the TSX approved the NCIB, which is the maximum number of common shares that may be repurchased under the NCIB. Purchases under the NCIB will be made on the open market through the facilities of TSX, other designated exchanges and/or alternative Canadian trading systems or by such other means as may be permitted by the applicable securities regulator. Daily purchases under the NCIB will be limited to 81,220 common shares, other than purchases made pursuant to the block purchase exception, representing 25% of the average daily trading volume of 324,881 common shares on the TSX for the six months ended June 30, 2026.

The actual number of common shares that may be purchased under the NCIB, and the timing of any such purchases, will be determined by management of the Company, subject to applicable law and the rules of the TSX. CIBC World Markets Inc. (“ CIBC Capital Markets ”) has been retained to act as the designated broker to make purchases of Mineros’ common shares under the NCIB. Mineros has established an automatic share purchase plan (the “ASPP”) in connection with the NCIB, under which CIBC Capital Markets may, subject to certain pre-established criteria, purchase common shares in accordance with the NCIB, TSX rules and applicable securities laws, including at times when the Company would ordinarily not be permitted to purchase shares due to regulatory restrictions and customary self-imposed trading blackout periods.

The ASPP is effective as of the commencement of the NCIB. Mineros may suspend or discontinue purchases under the NCIB at any time, subject to applicable securities laws, TSX requirements and the terms of the ASPP. Decisions regarding any purchases under the NCIB will depend on factors such as market conditions and the prevailing share price.

The NCIB will be funded from the occasional reserve approved at the special meeting held on July 14, 2026 Although Mineros intends to make purchases under the NCIB, there can be no assurance that any such purchases will be completed. The actual number of common shares to be repurchased, the timing of such repurchases and the price at which the common shares will be repurchased will depend on future market conditions. Common shares purchased under the NCIB will be withdrawn from circulation and held in treasury.
