November 2016 by Steve HerschbachDredges actually do pretty well in freezing conditions. There are a few tips you should know, however.
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.
The zone of influence of each sample must be carefully considered when deciding how far sample sites should be spaced from each other.
The prospects I found are known to carry heavy chunks of gold, sometimes in quartz, ironstone, or many times a rusty-looking type of shale covering.
There are several counties around Shasta County that offer very good gold detecting. Many of these locations are old hydraulic pits. While detecting these old pits over the years I have come up with some ideas on how to go about hunting them.
Most prospectors understand placer mining a lot better than hard rock mining and don’t realize the amount of work that goes into processing different types of hard rock ore.
We chatted for a bit and then we had to take off, but I kept what he said in the back of my mind as we rushed out to some other gold-bearing place in the Mother Lode to feed our gold fever.
We have a location where nuggets over an ounce have been detected over the past twenty years. This location is a small hilltop on which an ancient river channel once flowed.
