Mine typeFacility (Metal / non-metal)

MSHA cross-reference per the original MRDS record. Mine status and operator reflect MSHA's last published Mines export (February 2025); MSHA's public bulk feed has been unavailable since, so this may be out of date. See the Mine Data Retrieval System for current status.

Open MSHA's Mine Data Retrieval System for inspections, accidents, and violations for this mine.

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:

  • Homestake Mining Co. (25% Owner Of Rmtgc) — acquired by Subsidiary of Barrick Gold (2001)
    Operator of the historic Homestake Mine in South Dakota; acquired by Barrick Gold in 2001.
