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:

  • U.S. Steel Corp. — now part of United States Steel Corporation (2024)
    Mining operations largely divested over the late 20th century; the broader U.S. Steel entity was acquired by Nippon Steel in 2024 (mining footprint is now minimal).

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.
