The Cerro Lindo mine is an underground, polymetallic mine located in the Chavín District, Chincha Province, Peru, approximately 268 km southeast of Lima and 60 km from the coast. Access from Lima is available via the paved Pan American Highway south to Chincha, and then via an unpaved road up the Topará River valley to the mine site. Internal roadways connect the various mine site components. The approximate coordinates of the mine are 392,780m East and 8,554,165m North, using the Universal Transverse Mercator WGS84 datum and the mine site is located at an average elevation of 2,000 meters above sea level.
Operations began in 2007 and, in 2025, the Cerro Lindo mine produced approximately 87.1 thousand tonnes of zinc contained in concentrates, 27.1 thousand tonnes of copper contained in concentrates, 10.3 thousand tonnes of lead contained in concentrates, 3,953.2 thousand ounces of silver contained in concentrates and 4.1 thousand ounces of gold contained in concentrates. The ore is treated at a concentrate plant that has a processing capacity to 7.3 million tonnes of ore per year.

Cerro Lindo is classified as a volcanogenic massive sulfide (“VMS”) deposit. The Cerro Lindo deposit is 1,500 meters long, 1,000 meters wide, and has a current vertical development of 470 meters below the surface. Mineralization consists of at least 10 discrete mineralized zones. The Cerro Lindo deposit comprises lens‑shaped massive bodies, composed of pyrite (50.0% to 90.0%), yellow sphalerite, brown sphalerite, chalcopyrite, and minor galena. Significant barite is present mainly in the upper portions of the deposit. A secondary‑enrichment zone, composed of chalcocite and covellite, has formed near the surface where massive sulfides have oxidized. Silver‑rich powdery barite remains at the surface as a relic of sulfide oxidation and leaching.
In 2025, mineral exploration focused on expanding known orebodies southeast of Cerro Lindo, with particular emphasis on confirming the continuity and extensions of mineralization in Orebodies 8B and 8C. During 2025, we completed approximately 5.9 km of diamond drilling in 9 drill holes, divided between surface and underground exploration drillings.
During 2026, we will focus our efforts on geological activities intended to extend the life of the Cerro Lindo mine.
