The North Star Mine was located on Lafayette Hill a short distance south of Grass Valley, California, USA. It was the second largest producer of gold during California’s Gold Rush.[1] In 1898, the largest ever Pelton wheel for its time was built for the mine.[2][3] The North Star Mine Company also owned locations on Weimar Hill, adjoining and south of the North Star Mine.[4] It shut down during World War II after its consolidation with the Empire Mine.

Geography

The mine is located by Wolf Creek, on Auburn Road, a mile 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.[5]

History

The Lafayette ledge by Wolf Creek was worked since 1851, and was pronounced by the State Geologist in 1855 as being one of the best-producing for quartz mining in California. It was discovered during the time of the California Gold Rush by a group of men, principally Frenchman, who named their company, the "Helvetia and Lafayette Company". It changed hands in 1855, and again in 1857 (or 1860) when it was purchased under a forced sale for US$15,000. At the same time the name was changed to the "North Star." 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[6] 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 Grass Valley Gold District's deepest mine, measuring 4,000 feet (1,200 m) vertical depth.[3]

In 1895, Foote settled in Grass Valley, having been hired to design and construct an electric-generating plant for the mine.[7] At the North Star Mine Powerhouse, he installed the largest operating Pelton water wheel to that date;[8] it was the largest tangential water wheel in the world.[9] The powerhouse is a designated California Historical Landmark. In 1905, Julia Morgan designed a mansion for Foote and his wife, the illustrator and writer Mary Hallock Foote; the North Star House was listed on the National Register of Historic Places in 2011.[10]

In 1911, with his partners, Foote purchased the Tightner Mine in Alleghany, California.[11] Two years later, in 1913, he designed and built Foote's Crossing Road along the Middle Yuba River to improve transportation between the two mines; the road became a National Register of Historic Places landmark.[12]

Foote's son, Arthur Burling Foote, who started at the North Star as an assistant, went on to become the mine's manager after his father's retirement in 1913. In 1918, the North Star brought suit against the Empire Mine for underground encroachment upon its claim, but the boundaries were resolved, and the matter never went to trial.[13] By 1928, the North Star's total output value was approximately $33 million.[14] The following year, Newmont Mining Corporation purchased the Empire Mine and the North Star Mine, consolidating them to become Empire-Star Mines, Ltd. The Empire-Star was forced to shut down by the U.S. War Production Board during World War II.[15][16]

Miners

Superintendents and administrators included William H. Rodda (later of the Norambagua Mine), John C. Coleman (who was also president of the Nevada County Narrow Gauge Railroad),[17] his brother, Edward Coleman, and Arthur De Wint Foote. Its early owners were all miners such John Coleman, Edward Colman (John's brother), William H. Rodda, Josiah Rodda, John Rodda, William Kitto, William Hoskin, William H. Thomas, James Dods and John Harper.[18] The mine and mill employed over seventy men. Three-quarters of them had emigrated here from Cornwall, England where they had worked in the depressed tin mines. These Cornish miners introduced the Cornish pump and the Cornish pastie to the area.[19]

Operations

The North Star vein has an east and west course, with a dip of about twenty-three degrees to the north. This mine was opened by an incline shaft sunk on the course of the vein to a depth of nearly 700 feet (210 m). The lowest perpendicular depth attained was approximately 300 feet (91 m). It was opened by seven levels. The vein varied in thickness from a few inches to 4–5 feet (1.2–1.5 m), with an average of about 2 feet (0.61 m). The explorations in the fifth level extended about 700 feet (210 m) east of the shaft. The total known extent was estimated at 1,000 feet (300 m). The lower level was driven 550 feet (170 m) east of the shaft. Above the three lower levels, the ground is virgin to surface, and little was extracted from the two next to the bottom. The ore was raised by tram wagons on the incline, with a wire rope. The vein was enclosed in greenstone. A vertical hoisting and ventilation shaft was sunk 800 feet (240 m) east of the incline. This shaft was set to cut the mine on the level of the fourth gallery. The shoots of ore in this ground have an easterly pitch. The ore has had a gradually increasing tenor of gold.[4]

The North Star Mine Company owned 2,100 feet (640 m) upon the course of the lode. Between 1861-1865, the net returns were approximately $500,000, about one-fourth of which was expended in permanent improvements on the property. These included the drain tunnel, half a mile long, which was the most considerable item, and a new mill of sixteen stamps. About $375,000 of the net savings were returned to the owners in dividends, obtained from the use of a six stamp mill during 1862-63, which was subsequently enlarged. The returns for the year 1866 were $315,000, derived from the crushing of 6,000 tons of ore. The ores of this mine are considerably sulphuretted, but the value of the sulphurets in gold was much less than in the nearby Eureka Mine. The North Star did not possess chlorination works, but dressed their tailings by hand rockers for sale. The ores showed free gold, often in very fine masses, implanted in quartz, which resembles that of the nearby Rocky Bar Mine and Massachusetts Hill Mine.[4]

The sixteen stamp mill, erected in 1866, had a capacity of crushing about two tons to the stamp daily. The water in this mine was light, a supply for the use of the amalgamation works being derived from a neighboring ditch company. This circumstance, as well as the low angle of the dip of the vein, favored very greatly the economy of development of the North Star to a great depth.[4]
