Current operatorRio Grande Silver, Inc.
Current controller (parent)Hecla Mining Company
Mine typeUnderground (Metal / non-metal)

Inferred by coordinate + name similarity (6 m, 1.00 match). Confirm against MSHA if precision matters — non-USGS-curated cross-references may occasionally point at a neighbouring mine.

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. — acquired by Subsidiary of Barrick Gold (2001)
    Operator of the historic Homestake Mine in South Dakota; acquired by Barrick Gold in 2001.

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.
