Placer Channel Sampling
July 2013 by Jim HalloranSampling gold placers can be rewarding, but remember to treat the samples so you are not high grading or low grading your results. Learn the rules and apply them so your samples are accurate.
The amount of gold in the traces from the low-grade scattered veinlets may be much more than the traces from the small but rich pocket, at least until the pocket hunter closes in on the rich pocket. Further confusion arises if the prospector stumbles across a placer deposit on one of the higher peaks.
The question that most new people have is, “What do I detect?” Most people have a picture in their mind of what it takes to make what they are seeing a good place to detect. This is what I will try to sort out for you.
I have found gold more than 200 feet above the river. It was not unusual for nuggets of an ounce or more to be found in these deposits, but fine gold and flakes are much more common.
Today it is getting tougher and tougher to find a place to prospect. There is one significant haven left for the small miner...
One of the first minerals most prospectors learn to recognize is quartz, because, in the right circumstances, it can be an excellent indicator mineral for prospectors. Quartz is common, easy to identify, and is often associated with gold and other valuable metal deposits.
