Residual Placers: An Often Overlooked Gold Source
December 2021 by Chris Ralph
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.
My last update on this adventure was in the April 2012 issue and involved our search for the northern extension of the Cedarberg Mine. At that time we had found it and we were in the process of returning for some detecting when Mother Nature struck with a late rain and snow storm.
Once a seam is found it can be traced for miles in either direction. While you are tracing a clay line, you are looking for indicators. The indicators that I look for are ironstone, hematite, different color clays intermingled with the clay line, and a very iron-rich, brown gritty soil.
Oleophilic means "affinity to or attracted to oils," and this includes gold an diamonds.
Problems finding gold with a detector
…the “One More Time” has turned into three more trips and each of the three has yielded more gold each time down.
