ShapshotAfter 11 days of production stoppage, Buenaventura announced the restart of production at the Julcani mine as of December 27, 2022. Operations normalized after the cease of blockades near the entry of the affected mining units.

The Julcani operations were suspended in February 2023 due to anti-government protests. However, operations were fully reestablished on February 16, 2023.

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.
