Tyrone Mine

Description: Tyrone is an open-pit copper mining complex.

Did you know? The Tyrone mine is among the lowest grade ore bodies in the FCX mining portfolio.

Location: Grant County New Mexico, 10 miles south of the historic mining community of Silver City.

Ores: The Tyrone mine is a porphyry copper deposit. Mineralization is predominantly secondary sulfide consisting of chalcocite with leachable oxide mineralization consisting of chrysocola.

Processes and facilities: Tyrone's copper processing facilities consist of a solution extraction/electrowinning (SX/EW) operation with a maximum capacity of approximately 100 million pounds of copper per year.

Background: Prior to 1860, Native Americans mined turquoise at the site. Freeport-McMoRan Corporation (formerly Phelps Dodge Corporation) acquired mining claims in the area from 1909 to 1916, and began concentrating ore produced from large-scale underground mining in 1916. Operations ended in 1921. The property returned to operation as an open pit in 1967, with copper production from a concentrator. The SX/EW facility was commissioned in 1984. Tyrone’s concentrator suspended operations in 1992 when the property made the transition to SX/EW production.

Ownership: 100%.
