Placer Gold vs. Lode Gold (and how to find it!)

Placer gold mining is much easier. The gold is already separated from the rock, and gravity has concentrated the gold into creeks and rivers where it is more easily accessible. All the prospector needs is some simple tools, a gold pan and maybe a sluice box and they are ready to start mining. Lode gold takes a lot more equipment and generally a ...

The Geology of coarse gold formation

The Arizona Bureau of mines states in Bulletin 168 that "The origin of the placer gold, in Red Top basin at least, appears to have been the small quartz veins in that vicinity. The gold of these veins, like that of the adjacent placers, appears to be coarser than that of the Vulture vein".
