Book excerpt: The City of Juneau, Alaska was founded in 1880 following Chief Kowee's revelation to prospectors Joe Juneau and Richard Harris that there was gold in the stream now called Gold Creek in Silver Bow Basin. Juneau history has been firmly linked to gold mining. Prior to the mid 1940's, there were numerous small mining operations and three major mines in Juneau, the Treadwell Complex of four mines at Douglas, the Alaska Gastineau at Sheep Creek and the Alaska Juneau at Gold Creek. Each of these mines, at one point in time, was the largest low grade ore gold mine in the world. They are all long gone. The Alaska Juneau Gold Mine (The AJ) commenced operations in 1912. The AJ purchased the assets of the Alaska Gastineau Mining Company including the hydro projects at Salmon Creek and Annex Creek. They operated from 1912 until 1944, although they were not profitable after 1941. The manpower needs of WWII made the mining operations unprofitable because of the lack of miners to operate to the capacity required. The mill began operations in 1917 and processed more than 90 million tons of ore. This mine had more than 90 miles of tunnels on 15 levels. All of these fed ore to the mill at tidewater. At its peak of operation, it employed 3,000 miners though the usual number was closer to 1,000. Over its life, the AJ produced 2.9 million troy ounces of gold, 1.9 million ounces of silver and 40 million pounds of lead. This book illustrates what the mine looked like 30 years after it closed

Download or read book Mining Environmental Handbook written by Jerrold J Marcus and published by World Scientific. This book was released on 1997-05-03 with total page 816 pages. Available in PDF, EPUB and Kindle. Book excerpt: Negative environmental events make the headlines. Mining industry examples are the recent incidents at Summitville, Colorado, US, and the cyanide leak at Cambria Resource's Omai Operation in Guyana. In this volatile atmosphere, the publication of the Mining Environmental Handbook comes at an opportune time. It presents an objective, comprehensive and integrated examination of the effects of mining on the environment, and the environmental laws that deal with mining. Though stressing activities in the United States of America, it covers all of North America. North American environmental standards are currently being exported around the world. Consequently, this handbook will be of prime interest in countries that are now coming to terms with mining environmentalism. It should benefit working engineers and environmentalists, manufacturers, legislators, regulators, financiers and journalists. It has been selected as a university textbook. Finally, it will be an indispensable reference during serious discussions about mining environmentalism.
