Captain Jack Gold Mill (United States)

The Captain Jack Mill site is located at the headwaters of upper Left Hand Creek about 1.5 miles south of Ward in Boulder County, Colorado. The site is in a narrow valley known as California Gulch. Mining for gold and silver in the region began in 1860 and ended in 1992.

The site is comprised of the Big 5 Mine (the upper mine), Captain Jack Ltd. Mill, the Black Jack Mine (the lower portal), and other mines and waste features in the immediate surrounding area. The Big 5 Mine, located about 500 feet upstream from the mill, consists of an adit (tunnel), a large waste rock pile and a settling pond. The mill works area includes several lagoons previously used for settlings tailings from the mill. The lower portal includes the Black Jack adit and the contents of a shed.
