Searles Lake, California, contains the largest known domestic tungsten resource. The brines in this near-dry lake bed, located in the Mojave Desert 130 mi northeast of Los Angeles, contain an estimated 135 mmlb of tungsten. However, the low concentration of tungsten (0.080 G/l wo3) in the supersaturated brine makes selective tungsten extraction very difficult.
