Recovering Fine Gold with Oleophilic Adhesion

Some of the gold is placer that was beat up as it traveled; however, quite a bit of the gold is pocket gold that is running along the surface in this area.
The placer deposits of Utah occur in two distinct types of environments. These are 1) placers found adjacent to, and derived from, gold, silver and base-metal deposits; and 2) placers found in major rivers and derived from unknown, distant sources.
Hearty trees, shrubs and plants are a product of the soil conditions in which they grow, so it makes sense that roots near an ore deposit will take on nutrients containing metals if they are present.
We all continued over to another location at the top of a massive placer operation. Arriving at the draw, I showed everyone where gold had been found before and we all began detecting.
Looking at the exceptions to the basic rules is sort of an advanced prospecting discussion, but the readers of ICMJs Prospecting and Mining Journal are plenty able to handle it.
...day one was like watching the Gold Rush television show. He furiously worked the nozzle in an up and down fashion that resembled Jack Hoffman sitting on a backhoe.
We decided to run a detector over each piece. If we got a decent signal we placed the piece into a high-grade pile and the rest went into another pile to be worked on later. This high-grade pile wasn’t that large—maybe 25 pounds...
