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:

  • Kennecott Copper Corp. — acquired by Subsidiary of Rio Tinto (1989)
    Acquired by RTZ (now Rio Tinto) in 1989. Continues to operate the Bingham Canyon mine and other assets under the Kennecott name.

Curated by qvyshift.com from publicly-reported M&A activity (SEC filings, press releases, USGS Mineral Yearbooks). Not authoritative — verify against primary sources before relying on it. The MSHA panel above is the current authoritative source for actively-permitted mines.
