Excavator Testing Wet Placer Ground
April 2013 by Jim HalloranThe excavator or backhoe has become the tool of choice for testing placer ground. These machines are the best way to explore and sample a placer deposit if the ground is not too wet or frozen and bedrock is not beyond the reach of the machine.
Prospectors who specialize in nugget detecting are especially interested in this special desert type, as it produces nuggets that are close to the surface of the ground and therefore more suitable to be found with a detector.
You might think that gold prospecting techniques are basically the same everywhere, and in many instances you’d be correct. Some geographical locations, however, due to their unique geological conditions, present unusual challenges...
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.
Q: Will my detector react to fine gold?
There are a few questions you will need to ask yourself before you apply for a suction dredge permit from the State Water Resources Control Board.
We just completed a trip to another river, and yes, there was definite movement and redistribution of gravels, and other prospectors have seen this as well.
There are times when being able to recognize a type of rock can make you a much more successful prospector.
