Let’s take a look at these important property aspects individually, because they all affect the value of a property and how much mining companies might or might not be interested acquiring it.
Prospectors deal with black sands in lots of different ways. I know that some prospectors worry about getting every speck of gold and save black sands in buckets until they have hundreds of pounds.
An online video gave me some ideas, and with a lot of trial and error I developed a reliable method of panning free gold particles down below 35 microns quickly and easily.
Most placer equipment is really made with gold in the 30 and larger mesh sizes in mind, though if carefully used can often get reasonable recovery down to the 50 mesh size.
It’s accepted knowledge that wet methods will recover more fine gold than dry methods and processing the gravel as a whole will get more gold than only using a metal detector. The question is how much more?
After a short time, the tailings pile can get very large, and can actually block the downstream end of the sluice box.
