Silver Peak — lithium mine

Lithium brine operation in Clayton Valley, Esmeralda County, Nevada - in continuous operation since 1966 and the only producing lithium brine site in the United States. Covers over 13,500 acres (10,500+ owned), with rights to all economically recoverable lithium in the Clayton Valley Basin under a 1991 settlement agreement, senior water rights and land claims. Brine is concentrated by solar evaporation and converted to technical-grade lithium carbonate and hydroxide on site. The reserve plan runs ~28 years to 2053 with a ramp to sustainable pumping of 20,000 acre-feet per year (fixed sustaining capital ~$284M through ramp-up, then ~$20M/yr).
