en.Wedoany.com Reported - Lilac Solutions has selected Hatch as the engineering, procurement, and construction management company for its lithium carbonate facility at the Great Salt Lake in Utah, USA. This first-phase commercial facility will produce 5,000 tons of lithium carbonate annually, with initial production targeted for 2028. Hatch will be responsible for engineering, procurement, and management of construction and commissioning.
The agreement includes a limited notice to proceed, allowing for detailed engineering and early procurement work to advance ahead of a final investment decision expected later in 2026. The first-phase facility will be built on a 20-acre site on the north shore of the Great Salt Lake in Box Elder County, Utah, utilizing Lilac's fifth-generation ion exchange technology to directly extract lithium from salt lake brine. This process returns an equal volume of lithium-depleted brine to the lake, making it a non-consumptive process that does not lower the lake's water level. Taxes and royalties generated by the project will support lake conservation and create jobs in Utah. The active material ion exchange media used in lithium extraction will be manufactured at Lilac's facility in Fernley, Nevada, keeping the supply chain domestic and reducing reliance on Chinese suppliers.
Lilac CEO Raef Sully stated that Hatch has a long history in the lithium industry and the execution capability needed to bring the project online. With the Hatch team and global organization supporting the project, Lilac is ready to build. Conrad Blake, Managing Director of Hatch's Minerals business, noted that Lilac has developed one of the most innovative and technically robust direct lithium extraction technologies in the industry, and the Great Salt Lake project is a significant step for domestic lithium supply. Hatch looks forward to leveraging its project delivery expertise to bring the facility into successful operation. The north shore of the Great Salt Lake is estimated to contain 1.4 million tons of lithium carbonate equivalent, making it one of the largest discovered lithium resources in the United States. In 2025, Lilac completed pilot operations on the lake, achieving an average lithium recovery rate of 87% from high-sulfate brine containing only 70 mg/L lithium, demonstrating its ability to economically extract lithium from ultra-low-grade brine. Third-party sampling and laboratory analysis confirmed the performance of Lilac's ion exchange technology and validated the non-consumptive and non-polluting nature of Lilac's process.
Lilac has signed a binding 10-year take-or-pay offtake agreement with Traxys North America covering 100% of the planned first-phase production and has completed FEL-3 engineering. With the EPCM selection complete, the project is poised to become one of the first lithium brine projects in the United States to reach a final investment decision and begin construction.
