Golden Minerals Company
Mining Operations


Velardena MillingThe Velardeña Operations have two mills, each of which has its own tailings ponds:

  • 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
    • Concentrates are sold to various customers under exclusive annual contracts
    • 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.
    • This mill is presently idled and not in use.
    • There is a small refinery at the oxide plant capable of producing doré gold and silver bars. Golden Minerals produced doré during Q1 & Q2 2012.
