Nexa Resources S.A. informed that production at the Atacocha San Gerardo open pit mine is temporarily suspended. The Machcan community has illegal blocked the access to the mine due to protest activities, and although there is no material impact on Atacocha's production to date, mine production has been suspended, and activities are limited to critical operations with a minimum workforce to ensure proper maintenance. Nexa is complying with all existing agreements, pursuing an active dialogue with the community and authorities for a peaceful resolution of this situation and continuing to reinforce its commitment to the social development of all its host communities.

The 2023 production guidance is not expected to be materially affected and remains unchanged. On a weekly basis, Atacocha produces approximately 0.2kt of zinc, accounting for less than 3% of Nexa's zinc production. Nexa will keep the market informed of further developments.
