Expansion Plans
Acquisition of Pantera Lithium Resource
As of October 2nd, 2025, the expansion deal has been fully completed. On July 9th, 2025, EnergyX first announced that it has entered into a binding conditional agreement to acquire Daytona Lithium Pty Ltd, a wholly owned subsidiary of Pantera Lithium Limited (ASX: PFE), for A$40 million. As of October 2nd, 2025 the deal has been officially completed.
This landmark transaction secures full ownership of the approximately 35,000 gross acres of Smackover lithium brine resources in Arkansas, USA, adding to EnergyX’s existing 12,500 acre Texas position. Now with a total of nearly 50,000 acres in the Smackover, EnergyX aims to reinforce its dominance in North America’s most promising lithium region and accelerate its mission to establish a secure, sustainable U.S. battery supply chain.
This acquisition builds on the momentum of EnergyX’s Project Lonestar™, located in the Smackover Formation, which is designed to produce 50,000 tonnes per annum (tpa) of lithium hydroxide by 2030, with a first phase of 12,500 tpa by 2028. EnergyX owns rights to 330 acres of recently cleared land near to build its lithium mega refinery. The company has already had samples of lithium from its pilot plant in Austin, TX qualified by cathode customers.
