Let’s set up a thought experiment: Suppose you had some material that ran one ounce per ton gold, which is generally considered high grade to fantastic grade depending on the circumstances.
It was time to prime the pump and start the engine! Dan’s priming method is to use a small, submersible, 12-volt pump. My priming method is to use a hand-operated diaphragm pump.
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.
Ground sluicing, surfacing and scratching are a few names given to the recovery of gold in shallow areas. Where I live, the hills are dotted with small surface diggings.
My largest nugget from this area is almost one-half ounce. I’ve found several smaller chunks and many pickers in addition to the fines and flakes that I put in my poke.
There are many smaller old hard rock mines out there—more than you might think. There are some small hard rock properties that are even open to be claimed if one does the right amount of research to find them.
A large, 8-pennyweight piece popped out of a very small crevice where the water had been extremely swift in the winter, leaving no visible gravel.
