Opis

Mining historian Kerby Jackson introduces us to a classic lode mining work in this important re-issue of U.S. Geological Survey Bulletin 846-B, otherwise known as "Geology and ore deposits of the Takilma-Waldo district, Oregon (including the Blue Creek district)." Unavailable since the 1933, this publication was originally compiled by the United States Geological Survey and includes details on gold and copper mining in the Takilma and Waldo Districts of Josephine County, Oregon. The Waldo and Takilma mining districts are most notable for the fact that the earliest large scale mining of placer gold and copper in Oregon took place in these two areas. Included in this report are details about some of the earliest large gold mines in the state such as the Llano de Oro, High Gravel, Cameron, Platerica, Deep Gravel and others, as well as copper mines such as the famous Queen of Bronze mine, the Waldo, Lily and Cowboy mines. In addition to geological examinations, insights are also provided into the production, day to day operations and early histories of these mines, as well as calculations of known mineral reserves in the area. This volume also includes six maps and 20 original illustrations. Note: This edition is a perfect facsimile of the original edition and is not set in a modern typeface. As such, some type characters and photographs might suffer from slight imperfections or minor shadows in the page background.
