Mine Locations of the Chilson Brothers
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.
History of Arizona Gold Mining
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.
The Gold Cañon Placer Mining Colony
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.
History of the Elkhorn Mining District
The Elkhorn district was prospected early in the history of the State and numerous quartz locations were made in the years preceding 1870, but the district did not attract attention until the A. M. Holter lode became a producing mine.
The Los Burros District, Monterey County, California
The following notes concerning the metal prospects of the Los Burros district, in the southwestern part of Monterey County, California, are based on observations made during a visit of a few days to this section of the Santa Lucia Range in February, 1921.
The Mining Towns of California 1873
Tourists will naturally desire to visit some of the towns, where they can observe closely the various operations connected with gold-mining, which is such an important industry of California. This can be done by leaving the main line of railroad at any station in the mining-region and going a little way into the country. Indeed, on the main line of the Central Pacific are several towns, where almost the only occupation of the people is gold-digging.
Placer Examination - Principles and Practice
As the title suggests, the subject matter in this book deals for the most part with the examination and testing of placers. It is intended primarily as a guide for the professional mineral examiner who examines mining claims located on public lands of the United States.
City Stands Above Acres of Fire (1909)
When the Berkley mine broke out afire the other day in Butte, Montana, sending five hundred men to the surface and suspending operations for a month in one of the biggest producers of the greatest mining camp on earth -- the camp that gives to the world's market one-fourth of its copper production -- the sight of the flames and smoke didn't cause as much as a ripple of excitement on the surface of the busy population at the foot of the hill, for Butte is accustomed to a mine fire that is perpetual and which burns with intense heat in the ground under her very business district.
The Spenceville Copper Mine
The Spenceville Copper Mine, located in Spenceville, Nevada Co., California, operated between 1863 and 1918. In its day, it was considered one of the most long-lived copper mines in the state.
Gold Districts of California
California has been the source of more than 106 million troy ounces of gold, the most productive state in the Union. This digitized publication by the California Division of Mines & Geology contains information on approximately 350 gold mining districts.

Gold-Producing Districts of the United States" published by the USGS.
Historic Gold Production
The sources of data for the gold worksheet are the mineral statistics publications of the U.S. Bureau of Mines (USBM) and the U.S. Geological Survey (USGS)—Minerals Yearbook (MYB) and its predecessor, Mineral Resources of the United States (MR); and Mineral Commodity Summaries (MCS) and its predecessor, Commodity Data Summaries (CDS)
Two Montana Cities Part II Butte
The very activity of Butte is sometimes wearisome. It never ceases. By day and night the tall chimneys at the mills are pouring forth there smoke sand flame; the stress at all hours of thr day and night are filled with moving throngs.

The Legacy of the Bunker Hill Mine
Deep within the mountains of the panhandle of Idaho is a valley that white people named Silver. This valley is the heart of what became known as the Coeur d'Alene Mining District.
Two Montana Cities Part I Helena
The territory of Montana is in itself an empire. It was given Territorial rights in 1864, and since then has increases rapidly both in wealth and population. Fabulously rich in mines, already having an annual output of nearly $26,000,000, it is famous for it's vast areas of grazing land and becoming widely known as an agricultural country.
The Colorado Silver Boom
The Colorado Silver Boom was a dramatic expansionist period of silver mining activity in the U.S. state of Colorado in the late 19th century.
