Q: How do I improve my small-scale mining operation’s gold production?
Proper Spacing of Placer Sample Sites
The zone of influence of each sample must be carefully considered when deciding how far sample sites should be spaced from each other.
Proper Assaying of Placer Samples
The whole purpose of sampling mineralized ground is to measure the values in a small volume of material that would be representative of a much larger volume of similar material. The key word is representative. Chemical and fire assaying will not accurately represent placer deposits by themselves.
Early Summer Mining in Wyoming
Old tailing piles extend for miles. There was still plenty of water flowing here, so WPA members set up highbankers at several settling ponds.
