Book excerpt: The geology of the Black Hills National Forest is dominated by exposures of Precambrian rocks following erosion of the Paleozoic, Mesozoic, and Cenozoic sequences that were domed up from granitic intrusions and later eroded. Proterozoic plutonism metamorphosed and deformed many of the Precambrian rocks along with fault development. During these intrusive processes, gold deposits and associated mineralization occurred under several different types of emplacement. In addition to lode gold emplacement, erosion stripped many of the primary gold into placer gold deposits during Phanerozoic time. Three chapters are included to describe the geology of lode and placer gold in the Black Hills National Forest. Chapter 1 provides an introduction to the Black Hills geology. Chapter 2 presents Black Hills deposits mostly as lode gold deposits. Chapter 3 presents geomorphic descriptions of placer gold deposits and where they might be found.

This book was released on 2015-05-11 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rising out of the prairie, the Black Hills of South Dakota and Wyoming had long been rumored to have promising quantities of gold. Sacred to the Lakota, the Black Hills was part of the land reserved for them in the Fort Laramie Treaty of 1868. However, the tide of prospectors seeking their fortune in the Black Hills was difficult to stem. Members of the 1874 Custer expedition, lead by Gen. George Armstrong Custer, found gold. In 1875, scientists Henry Newton and Walter Jenney conducted an expedition and confirmed the rumors. By 1876, the trickle of prospectors and settlers coming to the Black Hills was a flood. The US government realized that keeping the interlopers out was impossible, and in 1877 the Black Hills was officially opened to settlement. In this sequel to their Black Hills Gold Rush Towns book, the authors expand their coverage of Black Hills towns during the gold-rush era.

Download or read book Placer Gold Deposits of Nevada (Classic Reprint) written by Maureen G. Johnson and published by Forgotten Books. This book was released on 2017-11-18 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Placer Gold Deposits of Nevada Following the discovery of placers at Gold Canyon, placer discoveries in Nevada were broadly in three periods: the 1860's to 1880's, when many small deposits throughout the State were discovered and sporadically worked and several large placers were discovered and extensively worked; the short period between 1906 and 1910, when very rich placers were dis covered at Lynn, Battle Mountain, Manhattan, and Round Mountain; the early 1930's, when economic conditions created by the depression caused a renewed interest in placer mining, and many individuals sought, and a few discovered, new placer areas throughout the State. The location of the placers described in this report is shown on plate 1. Very little factual information can be found about the early periods of placer mining in Nevada. For many placers, the only reports available are hearsay estimates of production and speculations about the extent of the placer ground based on remnants of placer pits, shafts, and other workings. Many of the placers said to have had a high production between 1860 and 1890 were worked by Chinese miners who came to Nevada dur ing the building of the railroads and stayed on to work at mining and other activities. The Chinese were reputed to be secretive with their earnings from the placers and did not ship the gold to the mint by Wells Fargo or other shippers. They worked the gravels very thoroughly in areas where American miners did not wish to expend great labor to win the gold. The placers in the Sierra and Spring Valley districts, Pershing County, were worked by Chinese miners; they have a very high estimated production before 1900 and a comparatively low known production since that time.
