The leases mark an expansion of Oxy’s current lithium efforts, which have been focused around the Salton Sea area of California, where the company's TerraLithium subsidiary is partnered with Berkshire Hathaway Energy.
The pair are looking to extract lithium from brines produced by Berkshire’s geothermal energy production. Oxy and Berkshire are due to begin construction of the first direct lithium extraction (DLE) pilot plant this year. If that is successful, the partners have discussed expanding operations in the region.
Oxy has a 100% interest in its leases in Arkansas,Hollub said, although Berkshire Energy has an option under its existing collaboration with Oxy to partner on future developments in the state if the pair were to choose to move ahead.
