Trail to Treasure
July 2015 by Adam HWe are both very experienced working this type of ground, and we quickly found the pay layer where we would focus our efforts. The bedrock has good gold, but so does the red hard pan.
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.
Rocks and minerals associated with clay seam gold deposits in southern Oregon are often in sedimentary rock units at least partially metamorphosed into argillite. They are also associated with mafic volcanic rocks, basalts and gabbro that...
Hearty trees, shrubs and plants are a product of the soil conditions in which they grow, so it makes sense that roots near an ore deposit will take on nutrients containing metals if they are present.
...I got the faintest of rises in the threshold. It was hardly a signal at all, and I thought it was one of the many, deep, hot rocks in the area.
There were iron stains all over and even a few places where I could see iron trash sticking out of the bedrock. These would be ideal spots to start with as the gold travels with the iron and lead.
Maybe we could find a few pieces of ore from that tunnel? It was worth a try. The old timers didn’t have that stamp mill for looks, so we set off to get some samples.
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.
