Nexa Reports First Quarter 2023 Exploration Results

LUXEMBOURG / ACCESSWIRE / April 24, 2023 / Nexa Resources S.A. (“Nexa Resources”, “Nexa”, or “Company”) is pleased to provide today the drilling and assay results from the first quarter of 2023. This document contains forward-looking statements.

Summary

Nexa’s updated Mineral Exploration program for 2023 comprises a total of 97,290 meters of exploration drilling, of which 36,340 meters are planned for Brazil, 53,950 meters for Peru and the remaining 7,000 meters for Namibia. The increase in the size of the program from the previously informed, 78,185 meters total planned drilling for 2023, is mainly due to an additional directional drilling exploration infill campaign taking place at the Babaçu deposit, within the Aripuanã mine area with an aim of expanding Mineral Resource and Mineral Reserve, and the inclusion of the drilling figures from early-stage exploration projects that are being reported for the first time. A total of 19,434 meters of exploration drilling were executed in the first quarter of 2023 through 20 operating drill rigs. From this total, 12,450 meters are from exploratory drilling (12 rigs), 5,391 meters from exploration infill drilling (6 rigs) and an additional 1,592 meters from early-stage exploration projects drilled in Peru. As in year’s past, drilling activity is lower during the first quarter due to the rainfall season in Brazil and Peru and corresponding delays in drilling contractors’ mobilization. We expect a ramp-up in drilling activities starting in 2Q23 onwards.

In Peru, 10,233 meters were drilled in 1Q23 with ten rigs. At the Pasco Complex, exploration activities continued to focus on the extensions of known satellite bodies like Porvenir Sur and Integración at El Porvenir highlighted by high-grade new intersections. At Cerro Lindo, drilling focused on the Pucasalla target, and at the mine site, on underground ore body expansion at Orebody 8, located southeast of the Cerro Lindo mine.

In Brazil, 9,201 meters of exploratory and exploration infill drilling were carried out with ten rigs in 1Q23. At Aripuanã, exploratory drilling has been focused on the northwest extension of Babaçu where new drilling continues to confirm high-grade Zn, Pb, Cu, Ag, Au mineralization, and exploration infill drilling at the Ambrex orebody for resource classification upgrade and to investigate the Ambrex/Babaçu transition zone at depth. At Vazante brownfield exploratory drilling in the “Extremo Norte” area continued confirming mineralization with continuity at depth, which provides good indication of the potential that still exists around Vazante.

In Namibia, no drilling was carried in 1Q23. Exploratory drilling will resume in 2Q23 focusing on exploratory targets at the Otavi and Namibia North projects to investigate potential areas with copper soil anomalies in favorable geology.

Commenting on the report, Jones Belther, Senior Vice-President Mineral Exploration & Business Development, said “Our brownfield exploration programs have continued to progress in the right direction with the goal of extending our current life of mine. Orebody 8 at Cerro Lindo has continued to be extended to the southeast highlighted by hole PECLD06657 with 25.1 meters grading 4.83% Zn,1.19% Pb, and 0.20% Cu, while drilling at Pucasalla has confirmed the continuity of zinc and lead mineralization, such as hole PECLD06670 with 7.4 meters @ 2.46% Zn and 1.04% Pb. At the Pasco complex, the Porvenir South and Integration orebodies continue to be expanded with drilling results of 6.5 meters @ 8.35% Zn, 2.49% Pb, 0.42% Cu, and 490.98 g/t Ag at Porvenir Sur, and 3.0 meters @ 7.83% Zn, 4.86% Pb, and 0.60% Cu, at Integración at level 3300.

At Vazante, drilling continued to confirm ore continuity at depth in Extremo Norte with high-grade intersections such as 4.9 meters with 18.28% Zn, 1.3 meters with 22.75% Zn, and 2.2 meters with 15.29% Zn. At Aripuanã, the Babaçu exploratory and exploration infill drilling revealed thick intersections with high-grade results like holes BRAPD000173, BRAPD000177 and BRAPD000115, respectively with 10.7 meters @ 18.84% Zn, 11.50% Pb, 216.23g/t Ag, 12.3 meters @ 17.63% Zn, 6.66% Pb, 0.61% Cu and 223.88g/t Ag, and 5.0 meters @ 9.25% Zn, 1.19% Pb, 2.40% Cu, 114.48 g/t Ag and 0.65g/t Au.

For 2Q23, we expect to complete 24,150 meters within exploratory and exploration infill drilling including 13,100 meters in Peru, 9,450 meters in Brazil and 1,600 meters in Namibia seeking new orebodies”.
