Federal records from BLM's Mineral & Land Records System, queried against the Census county boundary. Current to September 1, 2026. Federal cases only; private and state land are not represented. A lease or right-of-way that crosses a county line is counted in each county it touches.

Geothermal on federal land

Leased and released: 34 closed federal geothermal leases, none active.

34 leases on 82,671 acres have been closed out here. That cuts both ways: the resource drew interest, and prior holders let it go rather than develop it. The reason is usually resource, access, or economics, and it is knowable before you commit capital.

The private miles in between are the work.

Competing surface use

12,490 open mining claims compete for the same ground.

Mining claims don't stop a geothermal or right-of-way project, but they compete for surface, complicate siting and access, and each claimant is a party you have to deal with. 4,663 are active, 7,791 newly filed, 36 under review. Which ones actually sit in your footprint is a mapping question, and we answer it tract by tract.

Oil & gas

No authorized federal oil and gas leases, but 942 closed leases on record. The ground has been tried before.

What this page can't tell you

The private half of San Bernardino County isn't in any database.

Everything above is what the federal government controls. It does not show who owns a severed mineral or geothermal estate on private ground, whether that title is clean, what liens sit against it, or which families you'll be negotiating with. That lives in the San Bernardino County recorder's office, and it is the step that decides whether you can actually lease the ground.

    County title, tract by tract, with surface, mineral, and geothermal estates run separately. Then we lease it.
