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.

Download or read book Loafing Along Death Valley Trails written by William Caruthers and published by Pickle Partners Publishing. This book was released on 2017-01-12 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1926, on the advice of his doctor, former newspaperman William Caruthers, whose writings appeared in most Western magazines during a career spanning more than 25 years, retired to an orange grove near Ontario, California. Once there, he would go on to spend much of his time during the next 25 years in the Death Valley region, witnessing the transition of Death Valley from a prospector’s hunting ground to a mecca for winter tourists. This book, which was first published in 1951, is William Caruthers’ personal narrative of the old days in Death Valley—”of people and places in Panamint Valley, the Amargosa Desert and the big sink at the bottom of America.” A wonderful read.

Download or read book Skarns in British Columbia written by Gerald E. Ray and published by . This book was released on 1997 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Skarns in British Columbia have historically been important sources of iron, tungsten, copper, and gold. This publication begins with an introduction on skarn terminology and the problems of skarn identification. It then reviews a genetic model of skarn formation and presents descriptive profiles of eight types of skarn deposits; describes the database of at least 735 skarn occurrences in the province, and the number and distribution of skarns in British Columbia according to their associations, class, age, and distribution; and notes the ages of British Columbia skarns and the total production of various metals extracted from British Columbia skarns. Subsequent sections provide information on assays and metal ratios of mineralized skarns, skarn mineralogy, skarn mineral chemistry, chemistry of skarn-related intrusions, and the mapping and evaluation of skarns. The appendix contains a listing of 735 skarn occurrences in British Columbia, giving deposit name, MINFILE number, latitude/longitude, elements and minerals present, and associated rocks and their ages.

Available in PDF, EPUB and Kindle. Book excerpt: "Tonopah, Nevada, lies within the Great Basin region, an immense arid to semiarid area of 400,000 square miles extending between the Sierra Nevada and the Rocky Mountains. The environments -- roughly parallel mountain ranges and long desert basins -- makes harsh demands on its inhabitants. This history of Tonopah, which begins with a look at the land and its early inhabitants -- the pre-Archaic and Archaic Indian populations and the Western Shoshone, then vividly describes the arrival of white explorers, the discovery of silver, and the boomtown days of the mining camp....The spirit of the old west, embodied in its inhabitants' sense of adventure and their love of personal freedom, still exists in Tonopah"--Bk. jacket.
