The Patrick Purtell Collection of McLaughlin Mine Manuals was gifted to the Bancroft Library by Patrick Purtell.
Biographical / Historical
The Homestake Mining Company was founded by George Hearst, Lloyd Tevis, and James Ben Ali Haggin in 1877 after purchasing
the Homestake Mine in Lead, South Dakota from Moses Manuel. The Homestake Mine became one of the largest gold producing mines
in the United States. The mine ceased operations in 2001. That same year, Barrick Gold Corporation, headquartered in Toronto,
Ontario, Canada, acquired the Homestake Mining Company.
In 1981, the Homestake Mining Company purchased land situated in both Napa and Lake counties, California. This became the
site of the McLaughlin gold mine. The McLaughlin mine produced 3.4 million ounces of gold, making it the largest gold discovery
in 20th century California history. After its closure in 2002 the site became the Sylvia and Donald McLaughlin Ecological
Preserve. It is managed by the University of California, Davis.
