On August 12, Nexa Resources announced that its Cerro Pasco Complex, which includes the Atacocha and El Porvenir mines, has partially and temporarily suspended operations due to an illegal blockade by a small group from the San Juan de Milpo community. The blockade is part of ongoing protest activities and has not yet had a material impact on production, with the mines currently limited to essential safety and maintenance work.

Nexa stated it will continue constructive dialogue with the community and authorities to seek a peaceful and prompt resolution, reaffirming its commitment to the social and economic development of its host communities.

The Cerro Pasco Complex produces approximately 1,200 tonnes of zinc per week. Based on the company’s latest 2025 production guidance, El Porvenir is expected to produce 53–62kt of zinc in concentrate and 21–26kt of lead in concentrate, while Atacocha is forecast to produce 10–12kt of zinc in concentrate and 13kt of lead in concentrate. The guidance remains unchanged at this time.

SMM will continue to monitor the situation and provide updates as developments occur.
