 — Until the 1970s, mine operators could mine for valuable hardrock minerals—i.e., gold or copper—then abandon the land. On lands they oversee, federal agencies identified about 140,000 remnants of these hardrock mines, including unsecured tunnels and toxic waste piles. Hundreds of thousands more likely exist.

Lithium brine exploration has benefits from the angle of cost that make it less expensive than most comparable hard rock projects.
