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

No federal geothermal leasing on record here.

The federal layer is quiet. That can mean the resource isn't there, or that the ground is private and state and never shows up in BLM's record. The second case is common across the West, and it's where title work starts.

Rights-of-way · transmission & telecom

The private miles in between are the work.

Competing surface use

3,007 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. 1,858 are active, 1,147 newly filed, 2 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 288 closed leases on record. The ground has been tried before.

What this page can't tell you

The private half of Custer 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 Custer County recorder's office, and it is the step that decides whether you can actually lease the ground.
