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:

  • Newmont Mining Corp. — renamed to Newmont Corporation (2019)
    Renamed from Newmont Mining Corporation to Newmont Corporation in early 2020 (after the 2019 merger with Goldcorp).
