Workforce and safety, on MSHA’s records

MSHA · 2026-09

The US mine-safety regulator publishes employment, reported injuries and enforcement actions per mine. MSHA identifies 6of this entity’s mines; figures run 2000 to 2026. Employment is the regulator’s average-employee measure; a citation or order is an inspector’s action, reviewable in contest proceedings, not a court’s finding.

Injury and enforcement counts include contractor incidents at these mines, per MSHA’s own attribution; employment counts operator employees only, so the two must not be combined into a rate. Mine-level records sit under the operator MSHA lists, which can lag ownership changes. US mines only.

    • Production volumespublic, not ingestedUS filers disclose output in annual reports and, since 2021, S-K 1300 technical reports. Not yet ingested here, and a dormant registrant's EDGAR history may predate that rule.
    • Reserves & resourcespublic, not ingestedDisclosed under S-K 1300 for US filers since 2021; NI 43-101 and JORC apply elsewhere. Not ingested here - and a registrant that stopped filing before 2021 never came under the rule at all.
    • Financial statementspublic, not ingestedThe SEC holds this filer's history on EDGAR, free to read. Whether it extends to the present depends on the filer - several on this list stopped filing years ago.
    • Greenhouse-gas emissionspublic, not ingestedEPA's GHG Reporting Program publishes emitters above the reporting threshold. Held for facilities, not yet rolled up to the company.
    • Offtake & customerspublic, not ingestedMaterial contracts are exhibits to SEC filings, where the filer is still filing. Not yet extracted for this entity.

    "Licensed source" names the channel, not a vendor, and says nothing about what the data contains - only that reaching it runs through a commercial licence rather than a public register. "Not published" means no register or filing obligation we know of covers it, which is a statement about disclosure rules rather than about this entity's conduct.
