The Manantial Espejo project is located in the province of Santa Cruz, in the mineral-rich Patagonia region of southern Argentina, and is projected to produce an average of 4.1 million ounces of silver and 60,000 ounces of gold annually.

The mine plan for the Manantial Espejo project consists of two surface and two underground mines, a 2,000 t/d processing facility, expanded housing in the local community and participation in a new power line that will service the mine and the local community.

Ausenco’s scope included the full Engineering, Procurement and Construction Management services for the design and construction of the 2,000 t/d processing plant comprising conventional unit operations for crushing, grinding, gravity concentration, leaching and refining.
