EnergyX–Wildcat ‘battery mecca’ in Texas: project design and supply notes for mine planners
Reviewed by Joe Ashwell

First reported on MINING.com
30 Second Briefing
EnergyX and Wildcat Discovery Technologies plan a more than $230 million lithium iron phosphate (LFP) cathode active material plant in Hooks, Texas, co-located with EnergyX’s Project Lonestar lithium brine facility over 50,000 acres of Smackover formation mining rights. Phase 1 design capacity is about 15,000 tpa of LFP cathode material on a 330-acre TexAmericas Center site with rail access and existing utilities, targeting energy storage, EV, and defence platforms. EnergyX will supply discounted, price-banded lithium carbonate, while Wildcat brings a high-throughput cathode R&D platform and roadmap for higher-density, cobalt- and nickel-free chemistries.
Technical Brief
- DOE funding selection would accelerate construction, commissioning and scale-up of the Hooks LFP facility.
- Plant sits adjacent to the Red River Army Depot, targeting defence and military electrification supply chains.
- EnergyX’s 50,000 acres of lithium brine rights in the Smackover formation underpin long-term feedstock security.
- TexAmericas Center location provides existing rail access, utility infrastructure and competitively priced regional energy.
- JV expects ~150 permanent jobs plus 800–1,200 indirect and construction roles in northeast Texas.
- Both partners have already produced and customer-tested demonstration-scale LFP cathode and lithium carbonate in San Diego and Hooks.
- Wildcat’s high-throughput cathode R&D platform is geared to successive higher-density LFP and future cobalt/nickel-free chemistries.
- EnergyX’s broader portfolio spans lithium hydroxide for NMC, lithium metal anodes and lithium isotopes for nuclear supply chains.
Our Take
Project Lonestar at the Battery Mecca site builds directly on EnergyX’s recently commissioned 250 t/y LCE DLE plant on Smackover brines in Hooks, Texas (29 March 2026 item), signalling a shift from pilot-scale to an integrated lithium chemicals and cell-manufacturing hub in the same locality.
In our database, EnergyX’s MoU with Compass Minerals for a 30,000 tpa DLE/refining plant at Ogden, Utah (18 May 2026 item) plus this Texas Battery Mecca JV suggests the company is positioning its membrane tech as a platform across both inland brines (Smackover) and saline lakes, which could appeal to US utilities and OEMs seeking diversified lithium supply.
The presence of Lynas Rare Earths alongside lithium, cobalt and nickel in this Texas complex points to a multi-commodity critical materials cluster; our coverage of US-based rare earths and lithium projects indicates such clustering can materially de-risk permitting and infrastructure by spreading capex and political support across several strategic supply chains.
