East Texas Lithium

Battery-grade lithium carbonate from Smackover brine — extracted with DLE and powered by geothermal energy.

01Overview

Lithium carbonate from the Smackover, powered by the earth’s heat.

GeoFrame’s Green Lithium project produces battery-grade lithium carbonate from deep Smackover Formation brine in Mt. Vernon, Franklin County, Texas. GeoFrame controls more than 10,000 contiguous acres over one of the highest-grade lithium brine resources in the United States, supported by independent sampling and third-party resource assessment.

The same brine first drives zero-emission binary-cycle geothermal generators, fully powering the extraction and carbonate plant without straining the local grid.

02How it works

From reservoir to battery-grade lithium.

East Texas Lithium process: geothermal production wells, ORC power plant, pre-treatment, direct lithium extraction, concentration, crystallization, and drying, battery-grade lithium, and brine reinjection in a closed loop.
Closed loop

Brine is produced, powers the plant, gives up its lithium, and returns to the reservoir. Select a numbered stage on the diagram to see how it works. Click anywhere else to return to the full view.

03The opportunity

A domestic lithium source, built to scale.

Domestic supply

A U.S. source of battery-grade lithium carbonate, reducing reliance on imports for a critical mineral.

High-grade resource

Smackover brines are among the highest-grade lithium brine resources in the country.

Self-powered

Geothermal power from the brine itself runs the plant, with no strain on the local grid.

Low footprint

A compact, closed-loop process with no fossil-fuel energy use and lower capital intensity than hard-rock mining.
