The brief

Analyst view
  • Lilac's Great Salt Lake facility targets 5,000 tonnes per year of lithium carbonate by 2027, doubling U.S. production.
  • The company signed a binding 10-year offtake agreement with Traxys covering 100% of Phase 1 production.
  • A $100M DOE award and strategic partnerships with Hatch (engineering) and JordProxa (downstream conversion) de-risk construction.

Technical approach

As reported
Ion exchange

Gen 5 ion exchange media

Proprietary ion exchange resins selectively extract lithium from brine, working with various lithium concentrations from 70 mg/L to high-grade deposits.

Closed-loop

Non-consumptive process

The process avoids evaporation ponds and large water use; brine is returned to its source after lithium extraction.

Scalable

Works across brine types

The technology applies to lake brine, oilfield brine, and geothermal fluids, unlocking deposits at smaller scales than traditional mining.
