The North Star Mine and Powerhouse are located on Lafayette Hill a short distance south of Grass Valley in the U.S. state of California. It was the second largest producer of gold during California’s Gold Rush. In 1898, the largest ever Pelton wheel for its time was built for the mine. The North Star Mine Company also owned locations on Weimar Hill, adjoining and south of the North Star Mine. It shut down during World War II after its consolidation with the Empire Mine.

The mine is located by Wolf Creek, on Auburn Road, 1 mile (1.6 km) west of the Empire Mine. It is approximately 65 acres (26 ha) in size and situated in a southerly direction, the north boundary of the North Star being at an average distance of 430 feet (130 m) southerly from the Irish-American Mine. Within the surface boundaries of the North Star, there is a ledge of rock known as the "North Star Ledge", its top or apex wholly within the surface boundaries.

The French Lead, or North Star vein, was discovered in the Fall of 1851 by the Lavance Brothers, who with nine other Frenchmen, formed the Helvetia and Lafayette Gold Mining Company. In 1858, the sheriff sold the company to Edward McLaughlin to settle an $8,000 judgement. In Feb. 1860, it was purchased for $15,000 by the owners of the North Star Group, which became the North Star Quartz Mining Co. in 1861. The North Star Gold Mining co. was incorporated in 1867. The mine shut down in 1875 after reaching a depth of 1,200 feet. The North Star Mining Co. was incorporated in May 1884, by William Bowers Bourn II, and the mine was reopened. Bourn sold the North Star to James D. Hague in 1887. Hague reorganized the company as the North Star Mines Co. in 1889, and acquired Gold Hill, New York Hill, and the Massachusetts Hill mines.

The Lafayette Hill ledge by Wolf Creek was pronounced by the State Geologist in 1855 as being one of the best-producing for quartz mining in California.In the 1860s, reserves were estimated to be not less than thirty thousand tons, worth in the aggregate of $900,000.

Competition between Grass Valley Gold District's 95 mines was fierce, forcing them to open, close, and re-open at various times. Each was concerned with power sources to extract the gold. Many, like the North Star, used wood-fired engines to generate steam, depending on the surrounding forest for firewood. The North Star Mine was the Grass Valley Gold District's deepest mine, measuring 4,000 feet (1,200 m) vertical depth.
