Lilac Solutions Selects Hatch as EPCM Partner for Great Salt Lake Lithium Facility
Agreement advances project toward final investment decision expected later in 2026
Oakland, Calif., June 23, 2026 — Lilac Solutions, a leading provider of direct lithium extraction (DLE) technology, today announced it has selected Hatch as the engineering, procurement, and construction management (EPCM) firm for its Phase 1 commercial lithium carbonate facility on Utah's Great Salt Lake.
Hatch will support Lilac in the engineering, procurement, and management of the construction and commissioning of the 5,000 tonnes per annum (tpa) facility, with first lithium production planned for 2028. The agreement includes a limited notice to proceed, allowing detailed engineering and early procurement to advance ahead of the final investment decision expected later in 2026.
The Phase 1 facility will be built on a 20-acre site on the north arm of the Great Salt Lake in Box Elder County, Utah. It will use Lilac's Gen 5 ion exchange (IX) technology to extract lithium directly from lake brine and return the same volume of lithium-depleted brine back to the lake, a non-consumptive process that does not lower lake water levels.
The project is designed as a non-consumptive process that maintains lake water levels while enabling lithium extraction.
The project will generate local tax revenues and royalties to support lake preservation and create jobs in Utah. The IX media, the active material in the lithium extraction process, will be manufactured at Lilac's facility in Fernley, Nevada, keeping the supply chain domestic and eliminating dependence on Chinese suppliers.
“Hatch has a long track record in the lithium industry and the execution capabilities needed to bring this project online,” said Raef Sully, Chief Executive Officer of Lilac. “With Hatch's team and global organization supporting this project, we're ready to build.”
“Lilac has developed one of the most innovative and technically robust DLE technologies in the industry, and the Great Salt Lake project is an important step forward for domestic lithium supply,” said Conrad Blake, Managing Director, Minerals, Hatch. “We look forward to putting Hatch's project delivery expertise to work and bringing this facility online.”
The north arm of the Great Salt Lake holds an estimated 1.4 million tonnes of lithium carbonate equivalent, making it one of the largest identified lithium resources in the United States. Lilac completed pilot operations on the lake in 2025, demonstrating 87% average lithium recovery on a high sulfate brine containing only 70 mg/L lithium. Third-party sampling and lab analysis confirmed the Lilac IX technology performance and validated Lilac's non-consumptive and non-contaminating process.
Lilac has secured a binding 10-year take-or-pay offtake agreement with Traxys North America covering 100% of planned Phase 1 production and has completed FEL-3 engineering. With EPCM selection now complete, the project is on track to be among the first U.S. lithium brine projects to reach final investment decision and begin construction.
