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:

  • Stauffer Chemical Co. — dissolved ~1985
    Acquired by Rhône-Poulenc in 1985; agricultural and industrial chemical businesses dispersed through multiple owners over the following two decades.

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.
