Summary:
The Chino mine is a porphyry copper deposit with adjacent copper skarn deposits. There is leachable oxide, secondary sulfide and millable primary sulfide mineralization. The predominant oxide copper mineral is chrysocolla. Chalcocite is the most important secondary copper sulfide mineral, and chalcopyrite and molybdenite the dominant primary sulfides.
Summary:
Chino mine is an open-pit copper mining complex that has been in operation since 1910.
The available mining fleet consists of eighteen 240-metric-ton haul trucks loaded by three electric shovels with bucket sizes ranging from 31 to 48 cubic meters, which are capable of moving an average of 180,000 metric tons of material per day.
The highest bench elevation is 2,250 meters above sea level and the ultimate pit bottom is expected to be 1,508 meters above sea level. The Chino operation encompasses approximately 125,100 acres, comprising 109,000 acres of fee lands and 16,100 acres of unpatented mining claims held on public mineral estate.
