All the matters submitted to the shareholders, as set out in the Notice of Meeting and Information Circular dated February 18, 2025, were voted in favour, with the adjustment to elect six members to the board of directors of the Company (the “Board”) as Pieter Britz withdrew his nomination as a director.

Additionally, disinterested shareholders approved each of Nexa Resources S.A. (“Nexa”) and Compañia de Minas Buenaventura SAA (“Buenaventura”) 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 which would result in one or both such parties acquiring additional securities in the Company and, therefore, increasing their respective shareholdings to 20% or more of the issued and outstanding voting securities of the Company.
