Mine America Great Again
A sourced directory of U.S. mines, mills, smelters, refineries and separation plants, paired with an argument about the country’s lost processing capacity.
- For
- Researchers and businesses tracking U.S. mineral operations
- Worth noticing
- The directory distinguishes 154 working operations from 92 closed or idled sites and offers filters by commodity, state, facility type and status.
Field notes
The directory is organized around commodity, state, facility type and operating status, rather than presenting a simple list of companies. The homepage also lays out a chronology from the 1646 Saugus ironworks through the rise and decline of domestic smelting, and links its figures to sources including USGS and IEA publications. Supplier categories named for free listings include drilling, assay, equipment, permitting, haulage and processing.
