Exploration and Discovery of Base and Precious-metal Deposits in the Circum-Pacific Region During the Last 25 Years
Author: Richard H. Sillitoe
Publisher:
ISBN:
Category : Mines and mineral resources
Languages : en
Pages : 142
Book Description
This report describes the exploration and discovery histories of 54 major base- and precious-metal deposits around the Pacific rim over the last 25 years (1970-95). The discoveries are considered to be representative and to include all those of world-class deposits. Each case history places the discovery in a historical context and summarizes the geological, geochemical and geophysical work undertaken prior to discovery, followed by that completed through to production. The time frames and organizational aspects of the exploration programmes are emphiasized along with any special "twists". Each case history is prefaced by the background geology, including tonnage and grade data, and concludes with a brief summary.

Placer Gold Deposits of Nevada (Classic Reprint)

Languages : en
Pages : 146
Book Description
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.
