The Challenges

Initially, we completed a Bankable Feasibility Study for the project . We provided detailed engineering, procurement and constructionfor a large-scale, open-pit mine and a conventional concentrator capable of processing 40,000 t/d of ore.

Processing includes primary crushing, semi-autogenous grinding (SAG) and ball milling, and differential flotation to produce separate concentrates of lead and zinc, each containing significant amounts of silver. The final concentrates are transported via rail to the port of Mejillones in northern Chile and shipped to smelters around the world.  Ancillary facilities include access roads, power supply and a water supply well field.

 


 

Highlights:
  • One of the world’s largest and lowest-cost producers of both silver and zinc
  • Additional $200 million to oversee MSC work
  • Duration: Three years
  • 360,000 man hours
