February 13, 2023 at 16:25 PM EST

LUXEMBOURG / ACCESSWIRE / February 13, 2023 / Nexa Resources S.A. ("Nexa Resources", "Nexa", or "Company") is pleased to provide today the drilling and assay results from the fourth quarter of 2022 and full year of 2022. This document contains forward-looking statements.

Summary

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

At the end of 2022, cumulative drilling production reached 259,314 meters, of which 116,730 meters were exploratory drilling, including the Ambrex infill at Aripuanã, and 142,584 meters were operational infill drilling. Total exploratory drilling in 4Q22 was 25,722 meters, of which 11,596 meters in Peru, 11,202 meters in Brazil, and 2,924 meters in Namibia. Exploratory drilling planned for the next quarter includes 7,900 meters in Peru with eleven rigs and 8,300 meters in Brazil with nine rigs, totaling 16,200 meters.

Commenting on the report, Jones Belther, Senior Vice-President of Mineral Exploration & Business Development, said "During 2022 we achieved 95% of the planned activities with the execution of 116,730 meters of exploratory drilling out of the planned 123,300 meters. We achieved outstanding results in our brownfield program at Aripuanã with the Ambrex infill drilling confirming thick and high-grade mineralization, supporting the conversion of Inferred Mineral Resources to Indicated Mineral Resources. Drilling at Babaçu in 4Q22 also confirmed favorable high-grade intersections such as 26.0 meters @ 8.36% Zn, 2.74% Pb, 88.54g/t Ag and 0.15g/t Au, and 75.9 meters @ 5.65%Zn, 1.94% Pb, 26.14g/t Ag (including 25.2 meters @ 12.16% Zn, 4.47% Pb and 60.03g/t Ag).

Our brownfield exploration programs have progressed as planned and assay results continue to indicate that we can potentially extend the life of mine of our current operations. At Cerro Lindo, the Pucasalla target continued to be extended to the southeast with intersections greater than 4.0 meters as PECLD06461 with 34.0 meters @ 2.28% Zn, 0.55% Pb and 37.05g/t Ag. At the Pasco complex, the Integración orebody confirmed continuity in depth below the 3300 level in three holes with multiple intersections and hole PEEPD02339 with 9.2 meters @ 11.70% Zn, 7.16% Pb, 0.53% Cu, 66.71 g/t Ag and 1.07g/t Au opens a new mineralized zone to the NE of the Integración breccias. At the Porvenir Sur target, the PEEPD02401 drilling confirms mineralization in massive veins with high impact results, such as 6.1 meters @ 22.85% Zn, 13.71% Pb, 292.42g/t Ag and 0.74g/t Au. In the North Orebody, at the San Gerardo open pit mine, we confirmed the deep continuity of mineralization, highlighted by the hole PEATD01532 with 12.3 meters @ 0.75% Zn, 2.15% Pb, 32.97g/t Ag and 0.49 g/t Au.

Finally, in the Hilarión project, at the Hilarión Oeste target, located one kilometer southwest of the Hilarión deposit, new holes are confirming the mineralized skarn zone discovered in 3Q22, displayed as a parallel mineralized trend adjacent to the Hilarión deposit".
