A ‘geologic freak’ called the Smackover may end America’s lithium dependence on China, and Big Oil is already there

Standard Lithium and EnergyX are advancing direct lithium extraction (DLE) projects in the Smackover Formation, a geologic zone spanning Arkansas and nearby states, with Exxon and Chevron also holding positions in the region. The companies are betting DLE technology can turn the Smackover into a domestic lithium supply hub and reduce U.S. dependence on China, which dominates global lithium processing. The article frames the formation as a "geologic freak" whose brine resources could support commercial-scale output if extraction economics hold up. Specific project timelines, volumes and capital figures were not detailed in the provided excerpt. Next, watch for DLE pilot results and commercialization milestones from Standard Lithium and EnergyX, plus any expansion moves by Exxon and Chevron, as signals of whether the Smackover can deliver meaningful domestic supply.
