Placer Gold Deposits of Utah
December 2018 by Chris Ralph
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.
Chris got a nice target signal on the edge of rising bedrock, but still in a low, but washed area. After breaking up the bedrock, he recovered several pieces of gold amounting to almost three pennyweight.
It’s a common symptom of gold fever for miners to be very hesitant to let go of gold they’ve found or even have it made into jewelry. I confess, I suffer from the same incurable disease!
On our fourth trip, we finally reached the top edge of the old hydraulic pit, and it was monstrous.
These are entry-level machines designed with gold prospecting in mind and with the ability to handle mineralized ground and see nuggets of a grain or so in size, perhaps smaller.
I am going to break bedrock down a bit and explain my view of the varying scenarios I come across in the field.
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.
It’s accepted knowledge that wet methods will recover more fine gold than dry methods and processing the gravel as a whole will get more gold than only using a metal detector. The question is how much more?
