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.
Anyone who has found a patch knows the difficulties involved. Those who haven’t can guess, and with any effort will soon realize it.
…early last fall, I found my first gold-rich patch along a few crevices in the same river and found five grams of gold nuggets in one outing.
The type of mine dump that is best for metal detecting are the ones that consist of mixed sizes of rock and are located near some sort of excavation, commonly a shaft or adit. Sometimes the piles located along a trench dug by the miners can be productive as well.
Because of multiple take-out points along a ditch line, the ditches themselves become a wealth of knowledge to us present-day miners.
There is a material processing principle widely used in large milling operations to improve recovery that is poorly understood by most of the micro-mining and prospecting community...
Their rewards were far better than they had anticipated, resulting in one of the best clean-ups they had ever seen.
