bauxite mining grading stacking over band excavation estimate

Major Mines & Projects | Santa Rita Project

Santa Rita pit. The Santa Rita pit is a skarn type Cu-Au-Ag deposit (Bevan, 1973). The marble, garnet and epidote skarn rocks have been formed by the metamorphism of interbedded Cretaceous sediments of calcareous and siliceous nature and andesitic volcanics. The metasomatism was brought about by Tertiary intrusions, mainlydiorite and monzonite.
