About The Huanzala Mine

The Huanzala Mine in Peru, located in the Huallanca district of the Huánuco region, is one of the world’s most famous mineral-producing mines. Nestled in the Andes Mountains at high elevations, this mine is renowned for its high-quality and vividly crystallized mineral specimens, especially pyrite, galena, and sphalerite. The pyrite crystals from Huanzala are particularly notable for their large size, sharpness, and brilliant metallic luster, often exhibiting cubic or pyritohedral shapes that make them highly prized among collectors. In addition to pyrite, the mine produces other well-crystallized minerals, including fluorapatite, quartz, sphalerite and chalcopyrite, each renowned for clarity and intricate formations.

Operational since the early 20th century, Huanzala is primarily an industrial source of lead and zinc. However, its mineral specimens have attracted worldwide attention, positioning it as an important site for mineral collectors. The mine’s extreme altitude and challenging terrain make it difficult to access, adding to the allure and rarity of its minerals.
