Old Mine Sites and New Technology
September 2018 by Jack Geck
We’ve had two trips to the deserts of Nevada and explored mines and mill sites, hiked miles of ravines in California, and swung our detector coils over thousands of square yards of bedrock.
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.
This concept of detecting does not always work as we sometimes get a week or so where the temperatures rise to 116°—sometimes more.
What are the tell signs of garnet deposits?
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.
The same questions you ask yourself about gold trapping features in the present stream can be applied to the benches above the stream. Just imagine the stream at a much earlier time, before it cut its way down to the present level…
Winters are a great time to explore the hills in the area of the Middle Camp, Oro Fino and La Cholla placers on the southern flank of the Dome Rock Mountains.
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.
