North London Mine

Abstract

The North London Mine in the Alma district, Park County, Colorado was in operation in 1874 and was owned by the London Mining Company. Tenants Stamp Mill was built at London Junction around 1877 to process the ore from the Mine. A second stamp mill was constructed at London Junction in 1883, and during the first seven months of operation it produced $124,000 in gold bullion and 240 tons of concentrates, which were shipped to area smelters. The South London Mine, which was opened in 1892, then became the chief producer and during the late 1890s a tunnel was bored to connect the two mines. Between 1895 and 1931 the London Mining Company's gross profits were over $9,000,000. The South London Mine was operated until World War II, when all of Colorado's gold mines were closed down. The South London's machinery was sold and it closed in 1944.
