Prospecting for Gold at Green Valley
December 2012 by Don RobinsonIn October, five of us decided to take an exploration trip into an area called Green Valley. This was perhaps ten miles upstream from where we had gone in September and the difficulty was access. One would think that based on the name it was an easily accessible area not far from a nearby town. This couldn’t be more wrong.
I was able to remove the gravels with the assistance of a crowbar and I scooped them up with a garden trowel. This gravel contained over a pennyweight of gold and there were several 2-grain and 3-grain pieces…
Part I of the article addressed modern placer gold deposits. This second installment will address “ancient” flood deposits.
“Much of the ground where Ms. Hollingshead found her diamond is made of unweathered volcanic rock. When it rains, flowing runoff often leaves loose gravel, and sometimes diamonds, on the surface in these areas.”
When it was all setup and running, you had everything coming off the dredge riffles into the boil box. At the hole section, some of the water got sucked down and pulled a lot of black sand and over heavies…
As I planned for my trips, I concentrated on how to lighten my pack yet still carry enough gear to make the trip productive and enjoyable.
There were iron stains all over and even a few places where I could see iron trash sticking out of the bedrock. These would be ideal spots to start with as the gold travels with the iron and lead.
I’ve been following the precious metals for decades, and I haven’t seen a move this powerful in many years.
