The Heavy Minerals in Your Concentrates
June 2016 by Chris RalphThe fact that mineral deposits can contribute specific types of heavy minerals is why the analysis of the heavy mineral concentrates in the streams of an area can be an important prospecting technique for finding undiscovered mineral deposits.
I’m sure we all have, at some point in time, gone out detecting and ended up not having the success we thought we would have. Here are some helpful game-changers that work for me and may work for you, as well.
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.
My plan was to go up the canyon along a ridge and then drop into the canyon whenever I came across a spot that might give me reasonable access.
This was no ordinary nugget. It had not traveled very far from its nearby source, and that did mean a lot, as we were searching for the source of several such nuggets found during a gold rush that occurred in 1859.
His findings were not exaggerated—after running 82 buckets of gravels in two days we had a remarkable 27.8 grams of gold!
The biggest nugget I have found detecting here was three grams and the following weekend someone found a 9-gram nugget while detecting. Some have even found quarter-ounce nuggets, with one being a chevron nugget.
Most of us know making a profit as a small-scale miner is difficult; however, sometimes we combine luck with a little skill and bring home a few ounces of the yellow stuff.
