  • Epithermal
  • Vein / narrow vein

Summary:

The Saucito project comprises a system of epithermal veins containing silver, gold, lead and zinc. The veins are polymetallic, containing gold, silver, lead, zinc and copper mineralization in sulfides.

Mining Methods

  • Overhand Cut & Fill

Summary:

The Saucito-Jarillas service ramp has reached 3,000 metres length and the Saucito shaft has now reached 530 metres depth with 600 metres being the final target.

Processing Technologies

  • Flotation

Source: Subscription required

Summary:

Saucito’s beneficiation plant and process is very similar to that of Fresnillo. Saucito produces two types of concentrate; a lead concentrate, high in silver content, and a zinc concentrate. Crushed ore from the mine is fed into an SAG mill, where it is ground further and then passed into ball mills to further process it before passing to the flotation stage. The flotation process consists of two circuits to produce lead and zinc concentrates. Lead and zinc concentrate is loaded onto trucks for shipment to the Met-Mex refinery.
