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.
My girlfriend Beth and I decided to take our canoe down the Yukon and do some gold dredging...
The mysteries of this spot were only just starting to develop. There is nothing but very bland granite-type rocks here, meaning no bold, favorable indicators.
...your sampling procedures should not be designed to catch gold your mining technique will never recover.
Selecting the wrong coil can potentially cause you to miss nuggets, so you want to be sure to select the best option for the situation at hand.
Every year there are large nuggets found by the diligent, and occasionally by the lucky newbie.
Looking at the exceptions to the basic rules is sort of an advanced prospecting discussion, but the readers of ICMJs Prospecting and Mining Journal are plenty able to handle it.
