So, Where's The Gold?—Finding Gold Detectors Miss
December 2010 by Don RobinsonWe decided to run a detector over each piece. If we got a decent signal we placed the piece into a high-grade pile and the rest went into another pile to be worked on later. This high-grade pile wasn’t that large—maybe 25 pounds...
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.
Watching for these areas is one of my primary targets during the winter. It doesn’t take but a few inches of the surface moving away to give a fantastic target response that you didn’t hear prior to the washing of the surface.
Our research indicated this whole area had been claimed by Newmont mining company for several years, but when the price of gold dropped they let the claims expire, and we confirmed this with the local BLM office.
I probably swung over a few targets without noticing them. My first target came about ten minutes later as I went over a part of the high bench in this wide section of the dry wash.
For the last two years we’ve held a hands-on prospectors training session in the Iowa Hill district of California’s Mother Lode country as a part of our Gold Prospecting and Mining Summit event. Because of this, I thought it might be good to take a look at the history, geology and opportunities that the Iowa Hill district still offers to the individual prospector.
Across and downstream of our operation was a large pile of huge boulders. It was logical to think that water forces may have deposited gold in and around these boulders. We moved our dredge over and started pulling the rock pile apart.
Picking the right spot to placer has to do with years of experience, and a little luck. The textbooks can tell you where it should be, but sometimes the rules just don’t seem to apply.
