More than 300 prospects and mines are known to have existed in Virginia, yet very few, if any at all, are commercially active at this time. Amateur and hobby prospecting continues to this day, primarily consisting of individual or small scale placer operations. Many hobbyists simply use a gold pan or a sluice box.
Other gold rushes occurred in Papua New Guinea, Australia at least four times, Fiji, [3] South Africa and South America. In all cases, the gold rush was sparked by idle prospecting for gold and minerals which, when the prospector was successful, generated 'gold fever' and saw a wave of prospectors comb the countryside.
A geological survey is the systematic investigation of the geology beneath a given piece of ground for the purpose of creating a geological map or model.Geological surveying employs techniques from the traditional walk-over survey, studying outcrops and landforms, to intrusive methods, such as hand augering and machine-driven boreholes, to the use of geophysical techniques and remote sensing ...
Geobotanical prospecting refers to prospecting based on the composition and health of surrounding botanical life to identify potential resource deposits. [1] Using a variety of techniques, including indicator plant identification, [2] remote sensing [3] and determining the physical and chemical condition of the botanical life in the area, [4] [5] geobotanical prospecting can be used to ...
A gold pan. Gold prospecting is the act of searching for new gold deposits. Methods used vary with the type of deposit sought and the resources of the prospector. Although traditionally a commercial activity, in some developed countries placer gold prospecting has also become a popular outdoor recreation. Gold prospecting has been popular since ...
Recreational gold mining and prospecting has become a popular outdoor activity several countries, including New Zealand (particularly in Otago), Australia, South Africa, Wales (at Dolaucothi and in Gwynedd), Canada and the United States especially. Recreational mining is typically small-scale placer mining but has been challenged for ...

"Panning out" ~ Stereoscopic view of print taken by the U.S. Geological and Geographic Survey of the Territories ~ circa 1874–1879 Gold panning is a simple process. Once a suitable placer deposit is located, some alluvial deposits are scooped into a pan, where they are then wetted and loosed from attached soils by soaking, fingering, and aggressive agitation in water.
