Placer mining Wikipedia

Placer mining is frequently used for precious metal deposits (particularly gold) and gemstones, both of which are often found in alluvial deposits—deposits of sand and gravel in modern or ancient stream beds, or occasionally glacial deposits. The metal or gemstones, having been moved by stream flow from an original source such as a vein, are typically only a minuscule portion of the total

Further mining took place in 1909–13 and 1934, and sporadic alluvial mining and fossicking continues to the present. Alluvial gold was mainly found at the base of poorly sorted fluvial sediments within paleochannels overlying Adelaidean Tapley Hill Formation shale and siltstone that host minor auriferous quartz–carbonate–sulfide veins. The main gold producing areas were Brady’s Gully
