HISTORY
In the summer of 1859, a group of prospectors discovered rich placer ground on the north side of Farncomb Hill, and within the next 20 years, about $7,000,000 in gold was washed from the placers of the Blue River, Swan River, French Gulch, Illinois Gulch, and their tributary gulches. It was not until 1880 that gold was found in place on Farncomb Hill; for the next 10 years, the rich narrow vein of crystallized gold yielded most of the gold output. Gold dredges were introduced in 1898 and have been working the deep gravels of the larger gulches ever since, recovering a total of a little more than $7,000,000 in gold through 1937.
Lead-silver ores were first mined in the district in 1869, but little interest was shown in lead veins until the completion of the railroad from Denver to Breckenridge in 1880.
A wide variety of ore and gangue minerals has been found in the Breckenridge district, but the only ore minerals sufficiently abundant to be of commercial importance are gold, various silver minerals, sphalerite, galena, and pyrite. Contact-metamorphic ores, stock-works, veins, blanket ores, and placers have been exploited, but most of the output has come from the veins and placers.
