The Clayton Deep property is comprised of 83 unpatented 80-acre (32.4-hectare) placer claims totaling 6,640 acres (2,687 hectares). The claims cover the entire Southwest Gravity Low in Clayton Valley. The geologic formations that compose the surrounding mountain ranges contain unusually high concentrations of lithium. The project's claims lie less than 10 miles southwest of the only US-based lithium producing plant that has been in production since 1967, producing an estimated 40 million kg (44,000+ tons) of lithium through 2008 from the region's rich brines.[1]
