Velardeña Properties


Velardena MillingThe Velardeña Properties have two mills, each of which has its own tailings pond:

  • A 300 tonne-per-day flotation sulfide mill located near the town of Velardeña
    • The sulfide mill includes lead, zinc, and pyrite flotation circuits which produce lead, zinc and pyrite concentrates from the sulfide ore
    • Most of the silver is contained in the lead concentrate, while most of the gold has historically been in the pyrite concentrate
  • A 550 tonne-per-day cyanide leach oxide mill with a Merrill Crowe precipitation circuit and flotation circuit, located adjacent to the Company's Chicago mine (see photo, right). The oxide mill is presently leased to Hecla Mining Company, which began processing material at the plant in mid-December 2015. The lease period runs until mid-year 2017 and is currently extendable until end-2018.
