Placer Sampling for the Small-Scale Miner
October 2021 by Chris Ralph
I have seen many samples taken originally with an eye toward getting the highest grades possible, but later someone claims that those results represent an average grade of the whole gravel deposit.
Federal and state regulatory agencies often cite mercury and methyl mercury in our waterways as a major factor for further restrictions on placer mining, and on suction gold dredge mining, in particular. However, these regulatory agencies are minimizing selenium and its neutralizing effects.
Prospectors have many reasons why they might want to break rocks. These include dividing up a specimen too large to carry.
My girlfriend Beth and I decided to take our canoe down the Yukon and do some gold dredging...
At first we decided to see what the flat by our camp would produce where the old-timers had worked it with their Pelton wheel and dragline buckets.
So, I took the plunge. I decided on the maximum I would pay for the claim, then placed my bid. A day later I received a congratulations e-mail that I was the high bidder, and oh, by the way, send us your money.
Detecting is not very complicated and the rewards can be tremendous. The difference between success and fruitless toiling can be remedied by a few small adjustments and a whole lot of perseverance.
