Gold and Gold Mining in Ancient Egypt and Nubia
Author: Rosemarie KlemmPublisher: Springer Science & Business Media
ISBN: 364222508X
Category : Social Science
Languages : en
Pages : 664
Book Description
The book presents the historical evolution of gold mining activities in the Egyptian and Nubian Desert (Sudan) from about 4000 BC until the Early Islamic Period (~800–1350 AD), subdivided into the main classical epochs including the Early Dynastic – Old and Middle Kingdoms – New Kingdom (including Kushitic) – Ptolemaic – Roman and Early Islamic. It is illustrated with many informative colour images, maps and drawings. An up to date comprehensive geological introduction gives a general overview on the gold production zones in the Eastern Desert of Egypt and northern (Nubian) Sudan, including the various formation processes of the gold bearing quartz veins mined in these ancient periods. The more than 250 gold production sites presented, are described both, from their archaeological (as far as surface inventory is concerned) and geological environmental conditions, resulting in an evolution scheme of prospection and mining methods within the main periods of mining activities. The book offers for the first time a complete catalogue of the many gold production sites in Egypt and Nubia under geological and archaeological aspects. It provides information about the importance of gold for the Pharaohs and the spectacular gold rush in Early Arab times.

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.
