Operator history (post-MRDS)

MRDS records operators as of each record's last update (≤ 2019). Some of the operators listed here have since changed hands or dissolved:

  • Phelps Dodge Corp. — acquired by Subsidiary of Freeport-McMoRan (2007)
    Acquired by Freeport-McMoRan Copper & Gold in 2007 in what was then the largest mining-industry deal ever (~US$26 B).
