Jul 01, 2019 The case study shown in this paper corresponds to an open pit mine located the Andean region of Peru. This is a gold mineral deposit with a lithology consisting of pyroclastic rocks. Significant hydrothermal alteration has occurred in this region due to the mineralizing fluids which has attacked the country rock.

Venture, 2005) it is planned that mining will commence at Southwest Oyu. This open pit will initially produce at 25.5 Mt/a (70,000 t/d). By year 7 the first two open pit stages will be complete and the open pit operation will cease in favor of the higher value ore from Hugo North. At full production Hugo North will produce at 30 Mt/a (85,000 t/d).
