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:

  • Anaconda Co. — dissolved ~1977
    Acquired by Atlantic Richfield (ARCO) in 1977 and shut down most operations in the 1980s. Mineral assets were sold off piecemeal; some are now in Glencore via intermediate owners.

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.
