Mine Life2043
In April 2020, operations at Chino were suspended in connection with revised operating plans in response to the COVID-19 pandemic. During the first quarter 2021, Freeport-McMoRan restarted mining activities at the Chino mine at a reduced rate of approximately 100 million pounds of copper per year (approximately 50 percent capacity).

Deposit Type

  • Porphyry
  • Skarn


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.


Mining Methods

  • Truck & Shovel / Loader


Summary:

Chino mine is an is an open-pit copper mining complex located in Grant County, New Mexico. 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 122,800 acres, comprising 109,000 acres of fee lands and 13,800 acres of unpatented mining claims held on public mineral estate.

The available mining fleet consists of twenty-five 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.
