Attention to Detail - Part II
September 2016 by Ray MillsDitches almost always started in the high country and contoured the mountainsides, making a long drop, usually many miles away, to the goldfields. There are ditches in Trinity County that originate at seven and eight thousand feet in the Trinity Alps that carried water almost thirty miles.
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 a few questions you will need to ask yourself before you apply for a suction dredge permit from the State Water Resources Control Board.
After a while I got a very nice signal and out came a sweet kidney-shaped bit of gold weighing about three grams.
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.
When working fine gold placers with a drywasher, there are some natural variables that can be beneficial as well as others that can be a hindrance to achieving good recovery.
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.
We are both very experienced working this type of ground, and we quickly found the pay layer where we would focus our efforts. The bedrock has good gold, but so does the red hard pan.
