Using Geologic Maps
December 2015 by Chris RalphIn order to see what geologic maps can do, we need to think about what we are looking for.
The Wyoming Geological Survey released an online interactive map...
I had never run an impact mill before, but anything involving rocks, water and a big electric motor sounded great.
I love to dry wash old nugget patches found by detector operators, and I have found my fair share of gold dry washing those areas. I have also found a few nuggets using a detector on the bedrock exposed by dry washing the patches.
I regularly get inquiries along the line of: “Hey, I found this rock, and I think it might be gold ore. How can I tell?” Prospectors are always on the lookout for gold-bearing rocks that may be the source of any nearby placer gold.
Kimberlite is very difficult for geologists to find, let alone prospectors and rock hounds. This is because kimberlite is rarely exposed on the surface and few people know how to identify the rock.
His brother’s friend showed him a vial of gold that originated from his family’s mine in Honduras. Within two weeks Ernie had flown to Honduras to get a first-hand tour of the historic mine and the primitive operation underway to recover the gold.
I am going to suggest dozens of ways you can increase suction power, dredge to greater depths, and improve recovery methods in your sluice box.
