The mining, production, and assets of the present day Searles Valley Minerals Inc. have a long and varied history.

When John Searles arrived in the area in the 1860s, he was looking for gold and silver to mine. Instead he found a white crystalline powder, borax, in the dry Searles Lake bed. In 1873 he went into production as the San Bernardino Borax Mining Company to mine borax. Long mule teams were used to haul borax in wagons to San Pedro, until the much closer settlement of Mojave was used after the Southern Pacific Railroad reached it in 1876.

In 1895 The San Bernardino Borax Mining Company was sold by Searles to the Pacific Coast Borax Company, owned by Francis "Borax King" Smith. He shut down production at the company's section of Searles Lake the next year.
