Sampling Placer Stockpiles
August 2013 by Jim HalloranSampling other people's stockpiles or dumps has some inherent risks that sampling undisturbed ground does not have.
Several areas came to mind, but each was eliminated for one reason or another. One that seemed to be hanging on was the old historic mining town called Placerville.
These days they employ the use of metal detectors and carefully scan the shattered rocks, hoping to hear that sound we detectorists love to hear.
I recently grew complacent, and it caused me to make a mistake that resulted in the loss of a mining claim. It brought my mining plans for the summer to a complete halt.
Depending on the ore and if significant sulfides are present, a hard rock miner may be able to get away with simply using a flux to digest the other minerals that may be present.
We decided to check some spots that were pretty good to us on previous trips. The detector was deceptively simple with few buttons and auto-ground balance.
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.
I knew the nuggets got into the nugget patch somehow, I just had to figure out how and from what direction they came.
