Tinka Resources Ltd. has released the results of the company's annual general and special meeting (AGM) of shareholders, held on March 26, 2025.

A total of 175,747,137 common shares were represented in person or by proxy at the AGM, representing 43.00 per cent of the votes attached to all outstanding common shares of the company as at the record date. All the matters submitted to the shareholders, as set out in the notice of meeting and information circular dated Feb. 18, 2025, were voted in favour, with the adjustment to elect six members to the board of directors of the company, as Pieter Britz withdrew his nomination as a director. The following matters were approved at the AGM: (a) fixing the size of the board of Tinka to six; (b) the re-election of Ben McKeown, Dr. Graham Carman, Nick DeMare, Mary Little, Raul Benavides and Jones Belther as directors for the ensuing year; (c) the ratification of the company's stock option plan, pursuant to which the company may grant stock options up to 10 per cent of its issued and outstanding common shares at the time of the grant; and (d) the appointment of D&H Group LLP, chartered professional accountants, as the auditor of the company for the ensuing year at a remuneration to be determined by the board.

Additionally, disinterested shareholders approved each of Nexa Resources S.A. and Compania de Minas Buenaventura SAA becoming a new "control person" of the company should either Nexa or Buenaventura exercise the warrants previously issued to each of them, or should Nexa or Buenaventura participate in further investments in the company through private placements or other financings that would result in one or both such parties acquiring additional securities in the company, and, therefore, increasing their respective shareholdings to 20 per cent or more of the issued and outstanding voting securities of the company. Any future participation of Nexa or Buenaventura in a financing of the company is subject to the approval of the TSX Venture Exchange.

Subsequent to the AGM, the board reappointed Mr. McKeown as non-executive chairman, Dr. Carman as president and chief executive officer, Mr. DeMare as chief financial officer, and Mariana Bermudez as corporate secretary.
