Lithium claystone exploration at Willcox Playa

Lithium claystone exploration at Willcox Playa involves identifying and characterizing lithium‑bearing fine‑grained sedimentary rocks that accumulated in the closed basin environment of southeastern Arizona, with the aim of defining a potentially large, near‑surface lithium resource suitable for future extraction.[6] MAX Power’s work at Willcox included geophysical surveys and diamond drilling that intersected thick sequences of lithium‑rich claystone, indicating that the basin hosts a laterally extensive system of mineralized sediments.[6]
