Feather River Gold
February 2017 by Tom LeftwichI didn’t think too much of our dredge hole and we were both considering a move when we hit bedrock. There was a good quantity of flakes and fines, but no nuggets.
As we walked back we were just reaching the point of where the faulting should be and there, covered with deep grass, was very faint evidence of an old road going up the mountainside! What was that old road doing there?
Normally the detector he was using would sound off with a definitive high-to-low tone when passed over a piece of gold, which distinguished the gold from the many high iron content "hot rocks," but this one was different...
The box sat in a hallway and employees began using it for impromptu cricket games, no knowing what it contained.
It’s worthwhile for the prospector using a metal detector to know a little bit more about the association of iron and gold as well as how iron minerals affect your metal detector.
Palladium may well be an underexplored element and therefore an opportunity for prospectors and geologists. This is because they are often less than obvious and other than the native metals, a chemical analysis of samples is required to identify PGM-enriched rocks.
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.
So, how much rain does it take to cause a major movement of gravels in a stream and redistribute the gold? The technical answer is enough water to move the bed load of the river.
