When we got set up and I started to swing the coil over a small mound, I got a good signal, faint but repeatable.
Because the forces of erosion and gravity tend to carry lighter materials like quartz away more easily, the heavy minerals like gold or silver will tend to be concentrated in the general area around the vein outcrop. These concentrations are what make residual placers so attractive.
Digging in the right spots will produce excellent results, like this group of nuggets taken by the author while metal detecting during the last few months. The biggest nugget is over an ounce.
Before I tell you what dredging backwards is, I’ll tell you why my team and I decided to give this very unconventional dredging method a try.
Modern-day placer miners have many advantages over the prospectors of the gold rush days. Our prospectors can reap many benefits from accumulated knowledge of the last 100 to 150 years, which is a long and impressive list.
George was considering filling his dredge floats with closed-cell foam, ensuring that there would be no area available within each float for flooding.
Confluences of placer streams are well known as concentration sites for heavy minerals. The basic reason is that...
