Basic Geology for the Independent Miner—Part VI Geology of Placer Gold Deposits
June 2006 by Chris RalphPlacer deposits are the focus of many small-scale prospectors, as they can be worked with comparatively inexpensive equipment. In this conclusion of a six-part series, we will take a look at the geology and formation of placer deposits...

Few countries in the world can claim as lengthy a mining legacy as the Cornish of southwest England. Cornwall, a county situated at the farthest tip of the country at the edge of the Atlantic ocean, has been mined for tin deposits since the Bronze Age, 2100-1500 BC.
Rocky Bar sits on the north slope of Horse Ranch Mountain, and while the most productive placers were found in Bear Creek below Rocky Bar, most of the creeks on the south, east and north sides of the mountain contain placer gold and were worked commercially in the past.
The potential exists for small-scale placer mining in these pits using a trommel and sluice box or other similar types of equipment.
