The 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).
