Our History in Boron, California
U.S. Borax’s roots stretch back to 1872 when company founders began mining borates in Nevada. These pioneers discovered borates in Death Valley in 1881. They used teams of 20 mules and giant wagons to haul them 165 miles to the nearest railroad in Mojave, California. Our mine in Boron, California began as an underground mine in 1927 and was transformed into an open pit mine in 1957.
Today, we operate California’s largest open pit mine. The mine contains one of the richest borate deposits on the planet and supplies more than 30% of the world’s demand for refined borates.
