SnapshotIn 2023, there was a decrease in silver fed to the plant compared to previous years due to the formation of a subsea volcanic horizon impoverishing the mineralization in the Achilles sector. Therefore, during the year, search and reconnaissance work was intensified in areas where there are no such horizons. As part of this strategy, the pace of exploration and development has also been increased in the new Rosario Zone (Lv.610), where high-grade gold, silver and copper have been found and which will gradually come on stream during 2024.

Of the total of reserves, 70% belong to Acchilla mine, 21% to Estela mine and 9% to Rosario mine.

Acchilla is the main mining area.

Summary:

Julcani is a large polymetallic deposit in Central Peru, which principally produces silver that presents mainly as sulpho-salts in many mineralogically complex veins. They are hosted in dacite domes, tuffs, breccias and other tertiary volcanic rocks.

Julcani is a fracture-filling silver-bearing epithermal deposit with Ag-Pb-Bi-Cu-WO3 mineralization, hosted in a complex of dacitic/rhyolitic domes from the Tertiary. The most important system of structures runs NW-SE, followed by E-W and NE-SW. It is important to note the zoning, wherein the central part (Tentadora dome) exhibits an Au-Bi-WO3 ensemble that changes to Ag- Pb toward the edges. Historically, the most important mines have been Herminia, Nueva Herminia, Mimosa, and Manto. The Acchilla and Estela Mines are currently in operation. The minerals present include tetrahedrite, argentite, silver sulfosalts, galena, sphalerite, and chalcopyrite, with gangues of siderite, pyrite, barite, silica, and calcite.
