Nexa Reports Second Quarter 2022 Exploration Results

LUXEMBOURG, July 26, 2022 - Nexa Resources S.A. ("Nexa Resources", "Nexa", or "Company") is pleased to provide today the drilling and assay results from the second quarter of 2022. This document contains forward-looking statements.

Summary

Nexa's drilling strategy for 2022 is focused on near-mine expansion brownfield and infill drilling, including the Aripuanã project which is in the ramp-up stage. Additional exploratory drilling is also planned for greenfield projects with a favorable perspective.

Exploration expenditure and drilling production are running close to budget and drilling schedule. By the end of the second quarter, cumulative drilling production achieved 132,302 meters with 34,434 meters from exploratory drilling and 97,868 meters from infill drilling. Total exploratory drilling in 2Q22 was 18,339 meters with 12,357 meters from Peru, 4,412 meters from Brazil, and the remaining 3,231 meters from Namibia. Exploratory drilling planned for the next quarter includes 12,900 meters in Peru with nine rigs, 9,500 meters in Brazil with four rigs, and 2,500 meters in Namibia with two rigs, totaling 24,900 meters.

Commenting on the report, Jones Belther, Senior Vice-President Mineral Exploration & Technology, said "Our brownfield exploration programs are advancing toward expansion of our exploration portfolio and potentially increasing life of mine in our mining operations. Cerro Lindo Pucasalla's target has continued to be extended to the southeast highlighted by hole PECLD06064 with 4.4 meters grading 1.37% Zn and 0.72% Pb. At the Pasco complex, the Integración orebody continues to be expanded at depth in holes with multiple intersections up to 32 meters like 17.7 meters grading 1.91% Zn, 0.93% Pb, 43.74g/t Ag, and 0.65g/t Au. At the Asunción orebody in the San Gerardo open pit, we obtained several mineralized drill intersections such as 3.8 meters grading 1.63% Zn, 6.48% Pb, and 122.6 g/t Ag. At Morro Agudo/Bonsucesso, brownfield drilling continues revealing thick and high-grade mineralized intersections in the central zone of the mineralized body highlighted by hole BRMAMBSCD000239 with 8.8 meters grading 14.06% Zn and 2.86% Pb. An important confirmation of zinc and lead mineralization at the Poções target, located four kilometers northwest of Bonsucesso, opens the potential to expand Bonsucesso Mineral Resources. At Aripuanã, the Babaçu northwest extension confirmed thick and high grade intercept after assay results received in May 2022 with 231.5 meters grading 9.49% Zn, 3.65% Pb, and 0.13g/t Au including 56.6 meters grading 26.19% Zn, 9.14% Pb, 82 g/t Ag and 0.25 g/t Au".
