2016-6-19 A gold dredge is a placer mining machine that extracts gold from sand, gravel, and dirt using water and mechanical methods. The original gold dredges were large, multi-story machines built in the first half of the 1900s. Small suction machines are currently marketed as “gold dredges” to individuals seeking gold: just offshore from the beach of ...

During World War II the gold mining industry experienced another big downturn, from 731 mines in 1940 to 324 in 1943. By 1945 employment in the mining industry was at a third of its pre-war rate. Innovations in gold extraction during the 1950s and 1960s, such as portable one-man drills, tungsten carbide-tipped bits and electric locomotives, helped maintain production levels despite a shrinking work force.

The gold mines that were the focus of these forty-eighters and forty-niners fell into three major regions. The first discoveries were along the American River and other tributaries to the Sacramento River. Not long thereafter, gold was found in the tributaries to the San Joaquin, which flowed north to join the Sacramento in the great delta east of San Francisco Bay.

Gold. The first major discovery of gold in Western Australia in the 1890s initiated a period of growth and transformation for the struggling colonial state. Fortune-seeking prospectors helped establish a significant gold mining industry by 1900. Over a hundred years later, the Western Australian goldfields still produce most of Australia's gold.

Early Gold Finds and Production. Gold was produced in the southern Appalachian region as early as 1792 and perhaps as early as 1775 in southern California. The discovery of gold at Sutter's Mill in California sparked the gold rush of 1849-50, and hundreds of mining camps sprang to life as new deposits were discovered.

2010-1-13 These miners were some of the initial developers of the present gold panning area. In 1899-1900, Vaughan and Greenwell hand dug a mining ditch from a point above Libby Creek Falls to their mining claims. This 6,000-foot-long ditch supplied water necessary for placer and subsequent hydraulic mining ventures. B.F. Howard (1914)
