The next era of U.S. industrial leadership will depend on clean energy and critical minerals

CTR is developing its Hell’s Kitchen resource in Imperial County, California, within the heart of the Salton Sea Geothermal Field – one of the world’s most prolific geothermal and critical minerals resource areas.

Located ~200 miles southeast of the City of Los Angeles and ~120 miles east of the City of San Diego, the Hell’s Kitchen Project Site is close to well-established local infrastructure, roads, rail, deep-sea ports, and gateway cities.

Over Four Decades of Commercial Geothermal Operations

Electrical generation from the Salton Sea Known Geothermal Resource Area began in 1982 and has operated for over 40 years with no major declines in pressure, temperature, or production, demonstrating a large, long-life raw-material supply source.

Reservoir temperatures are among the hottest of any geothermal area in the world, with measured values up to 734°F (390°C).

CTR Demonstration and Optimization Plant

Demonstration and Optimization Plant Delivers 95–97% Lithium Recovery

CTR operated an onsite Demonstration and Optimization Facility to identify optimum operating conditions for the brine conditioning and processing through a 1/15th commercial-scale Direct Lithium Extraction (DLE) circuit.

Operation of the brine conditioning system successfully produced stable, high-quality brine feed for DLE via an adsorption process.

Definitive Feasibility Study Supports 30-Year Operating Life for Stage 1

Baker Hughes’ geological assessment, well modeling, and reservoir simulation estimated geothermal power potential and lithium production for Stage 1.

The modeling followed state-of-the-art technologies and reserve/resource classification guidelines as outlined by the SEC under S-K 1300.

Stage 1 Resource Estimates:
  • Total Measured and Indicated Resource: 1.7 Mt Lithium Hydroxide Monohydrate (LHM) at 219 ppm
  • Measured Category: 0.6 Mt LHM at 219 ppm
  • Probable Reserves: 0.9 Mt LHM at 217 ppm (30-year life)

Hell’s Kitchen will operate within the largest mineralized geothermal brine resource in the United States

According to an assessment from the Lawrence Berkeley National Laboratory 'Characterizing the Geothermal Lithium Resource at Salton Sea, 2023', the Salton Sea Geothermal Reservoir is estimated to contain a proven lithium resource of 4.1 million metric tons of Lithium Carbonate Equivalent (LCE) and a probable lithium resource of 18 million metric tons of LCE.

Key Benefits of Integrated Power and Critical Minerals Production

Steam separation

Steam separation from brine uses conventional technologies

Brine purification

Integrated brine purification and lithium conversion maximizes efficiency

Water recycling

Water is recycled to minimize consumption

Steam use

Renewable steam is used to concentrate lithium solution

Lithium conversion

Conventional process used to convert lithium chloride to battery-grade products

Geothermal consistency

Geothermal resource produces consistent feed brine composition
