The Colorado Mining Directory of 1883 called Leadville the “natural successor to Australia and California.” In the century since that statement was made, interest has never waned and production has never entirely ceased. Not only valuable ore but also fine mineral specimens have been recovered and preserved from many of the nearly 2000 mines in the Leadville area.
This collection of over 475 mining districts in the state of Nevada was compiled from reports by the Nevada Bureau of Mines and the USGS.
Eighty-seven placer districts in Arizona are estimated to have produced a minimum of 564,052 ounces of placer gold from 1774 to 1968. The location, areal extent, past production, mining history, and probable lode source summarized for each district are based on information obtained from a wide variety of published reports relating to placer deposits. Annotated references to all reports that contain information about individual deposits are given for each district.
The California gold rush of 1849 has the distinction of being the first modern international gold rush. It is lesser known that gold had been discovered in California prior to the great rush. This article explores both the first significant gold discoveries in California, and the events surrounding James Marshall`s discovery of gold in 1848.
From the May 15 1926 Arizona Mining Journal - the authentic history of the mining activities of the Chilson brothers who were active in the locating and developing of Arizona’s mineral resources.
Gold mining in Arizona did not start to any appreciable extent until after the acquisition of the territory by the United States from Mexico in 1848 and 1853.
Gold dust was discovered in the Carson Valley as early as 1848 by Mormons traveling to the gold fields of California. However, with seemingly better prospects on the other side of the Sierras, and with supplies dwindling after the long desert crossing from Salt Lake City, nobody stayed to work these placers until at least 1850. By 1851 a small and remote mining colony had formed and was known as the "Gold Cañon Placer Mining Colony", located roughly where the town of Dayton still is today.
Silver Lake, which early settlers called Arrastra Lake, lies in a basin at the head of Arrastra Creek, four miles southeast of Silverton, Colorado, near the center of the Las Animas Mining District, in what was then part of La Plata County. Silver Lake Basin was one of the West's most isolated and difficult to access districts. This article explores the incredible feats of transport and engineering were required to make the mines of Silver Lake successful.
