Prospecting for Surface Flood Gold Placers on Low and Intermediate Gradient Streams
February 2015 by Alex DolbeareSample panning is a very important method used to find the richest parts of a flood gold deposit before setting up equipment and running material.
Ditches 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.
I worked my way to a flat area along a ridge where I could see a quartz blowout. As I got within 100 feet of it, I started seeing rock that I knew to be associated with gold.
A retired gold prospector spent hours digging up his fortune in the northern goldfields near Kambalda, Western Australia, after finding the target with his metal detector.
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.
With a little homework and a methodical approach to sampling, a prospector can determine if a deposit is worthy of more of an investment...
Within a few minutes I got my first signal and dug out a small flake about three grains.
Chances are better that both types of gold did not come from the same source. Let's look at the probable conditions to cause two types of gold in a placer.
