I suspect detailed geological mapping and prospecting would lead to discovery of one or more overlooked gold deposits in the district even though it has been heavily prospected in the past.
An online video gave me some ideas, and with a lot of trial and error I developed a reliable method of panning free gold particles down below 35 microns quickly and easily.
As I laid in my Jeep and tried to get some rest, I began to realize how tired I was. I felt like a little kid who walked around Disneyland for 12 hours with his parents.
Many years ago I was in the American Canyon. I remembered a few details about a placer deposit there, so we decided to make a trip down and re-check some of these old workings.
Depth is not an issue unless the site is thoroughly cleaned of shallow trash, and it is far easier to isolate and remove targets using a small coil in a target rich location.
Much more information can be gained from that single source and gives you ideas on the gravels for dry washing or where the nuggets may lie for metal detecting
“I heard him hollering down in the hole as soon as I got there,” he said. “I was just glad to see him alive.”
