The Huanzala mine in Bolognesi Province, Áncash, Peru is an excellent example of a mine with exceptional quality, variety, and availability. Traditionally a lead-zinc mine, Huanzala holds the record for the most mineral tonnage extracted by a single mine. This is quite the feat and it's easy to see why minerals from this locality are so aggressively mined and collected.

This mine has a multitude of awesome minerals, from sharply terminated quartz, to sparkly pyrite, bubbly aragonite and dense galena. Other common minerals are realgar, orpiment, sphalerite, chalcopyrite, manganoan calcite, rhodonite, rhodochrosite, cassiterite, barite, fluorite and fluorapatite, among other less prevalent minerals. Mineral associations from this mine often contain three to four minerals that look phenomenal growing all over one another.
