Gold Mining in the Nineteen Nineties


Book Description

GOLD MINING IN THE 1990's--This one book outlines EVERYTHING a beginner will need & want to know about getting started at gold mining today, either as a hobby or as a small-scale commercial activity. In easy to understand language, supported by clear photographs & graphic demonstrations, this book covers all of the important subjects--including what gold is & looks like, where it comes from & where to find it, how gold deposits & how to find & recover it, & also touches on the legal aspects of how to claim the gold for yourself. The book covers the up-to-date mining procedures of panning gold, sluicing, dredging, high-banking, drywashing, electronic probing, hardrock mining, basic refining techniques, cleaning procedures, selling gold, & much, much more. Herein lies the most comprehensive & thorough work on electronic prospecting techniques (locating gold with metal detectors) available in any publication on the market today. Virtually an encyclopedia of modern gold mining techniques, there is no other book available more up to date, more simple to understand, or which covers the entire subject as thoroughly as this manual.




Shifting Livelihoods


Book Description

Honorable Mention for the Society for the Anthropology of Work (SAW) Book Prize The many dimensions of gold in a shadow economy People employ various methods to extract gold in the rainforests of the Chocó, in northwest Colombia: Rural Afro-Colombian artisanal miners work hillsides with hand tools or dredge mud from river bottoms. Migrant miners level the landscape with excavators, then trap gold with mercury. Canadian mining companies prospect for open-pit mega-mines. Drug traffickers launder cocaine profits by smuggling gold into Colombia and claiming it came from fictitious small-scale mines. Through an ethnography of gold that examines the movement of people, commodities, and capital, Shifting Livelihoods investigates how resource extraction reshapes a place. In the Chocó, gold enables forms of “shift” (rebusque)—a metaphor for the fluid livelihood strategy adopted by forest dwellers and migrant gold miners alike as they seek informal work amid a drug war. Mining’s effects on rural people, corporations, and politics are on view in this fine-grained account of daily life in a regional economy dominated by gold and cocaine.

Gold and Gold Mining in Ancient Egypt and Nubia


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.




Going for Gold


Book Description

Details how Newmont Mining revolutionized the gold mining industry and remains the second largest gold miner in the world Jack H. Morris asserts that Newmont is the link between early gold mining and today’s technology-driven industry. We learn how the company’s founder and several early leaders grew up in gold camps and how, in 1917, the company helped finance South Africa’s largest gold company and later owned famous gold mines in California and Colorado. In the 1960s the company developed the process to capture “invisible gold” from small distributions of the metal in large quantities of rock, thereby opening up the rich gold field at Carlin, Nevada. Modern gold mining has all the excitement and historic significance of the metal’s colorful past. Instead of panning for ready nuggets, today’s corporate miners must face heavy odds by extracting value from ores containing as little as one-hundredth of an ounce per ton. In often-remote locations, where the capital cost of a new mine can top $2 billion, 250-ton trucks crawl from half mile deep pits and ascend, beetle-like, loaded with ore for extraction of the minute quantities of gold locked inside. Morris had unique access to company records and the cooperation of more than 80 executives and employees of the firm, but the company exercised no control over content. The author tells a story of discovery and scientific breakthrough; strong-willed, flamboyant leaders like founder Boyce Thompson; corporate raiders such as T. Boone Pickens and Jimmy Goldsmith; shakedowns by the Indonesian government and monumental battles with the French over the richest mine in Peru; and learning to operate in the present environmental regulatory climate. This is a fascinating story of the metal that has ignited passions for centuries and now sells for over $1,000 an ounce.
