The Project is targeting production of up to 45,000 tonnes per annum of battery-quality lithium carbonate in two phases of 22,500 tonnes per annum each. A Definitive Feasibility Study (DFS) and Front-End Engineering Design (FEED) are currently underway to support this expansion. We are targeting commencement of construction in 2026 with first production as early as 2027 and commercial operations in 2028.
The South West Arkansas Project is located in the Smackover, where the USGS estimates between 5.1 and 19.0 million metric tons of lithium to be present.1
