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.
The pile up on the small hill had to be a couple yards of black sand. I’m not one to ignore a little gold even if it is small in size—I have always believed that gold fever comes in all sizes.
My first personal experience with placer diamonds was on a gold prospecting trip in Indiana about 8 years ago, when a fellow prospector was cleaning his gold concentrates.
The total after a great day added with the previous days put them up to 9.07 pennyweight—just under a one-half ounce of beautiful California gold.
It is better in a gem and mineral mining operation that the driller, blaster and mucker be the same person in order to be able to predict placement of the desired mineral enriched pockets.
There are currently about 170 commercial-scale placer operations in Alaska. Most of these are small operations with just a few people working; they are often family affairs that operate seasonally only during favorable weather.
The gold in this area can get quite large. Most of the pieces are about half a pennyweight on average.
At first, I tried to shift things around, but then a hand with a rock would appear, so I would stop trying to adjust my gear and grab the rock to keep things moving.
