Gold Mining Methods - groundtruthtrekking

Placer mining targets "native" gold that isn't chemically bound up within the rock itself. The sources of all placer gold are "lodes", or veins of gold naturally formed within the rock. Ongoing weathering and erosion of rock outcrops continuously exposes new fragments of gold that wash downstream. Because gold is far denser than most rock (19.3 g/cc as opposed to about 2.7 g/cc) it settles ...
