  Location of North Bloomfield Mining and Gravel Company in California | |
The North Bloomfield Mining and Gravel Company of North Bloomfield, California, was established in 1866 and operated a hydraulic gold-mining operation at the Malakoff Mine subsequent to the California Gold Rush. In its day, no other company's operations matched North Bloomfield Mining and Gravel Company in size or expense. The company operated until 1910. In the years prior, its profits and procedures had been reduced due to the landmark ruling of Woodruff v. North Bloomfield Gravel Mining Company. [1]
The mine is located within Malakoff Diggins State Historic Park, 16 miles (26 km) east of Highway 49 on Tyler Foote's Crossing Road, and 28 miles (45 km) north of Nevada City, California.[2] The company office is still standing.[3]
