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.
The fact that mineral deposits can contribute specific types of heavy minerals is why the analysis of the heavy mineral concentrates in the streams of an area can be an important prospecting technique for finding undiscovered mineral deposits.
Located 23 miles south of Libby, the land surrounding the Libby Creek area has been of interest to prospectors since the early 1860s, when it was home to up to 600 miners working at a camp known as Libbysville.
There is a major change coming in the economy of the world and now is the time for prospectors and miners to grab a ticket and get on board.
This explains the large difference in particle sizes between placers and hydrothermal lode deposits, but also means that while the mining may be similar in some cases, the sampling and recovery techniques are usually quite different.
Old tailing piles extend for miles. There was still plenty of water flowing here, so WPA members set up highbankers at several settling ponds.
The non-toxic thiosulfate is actually the medical antidote given to people for cyanide poisoning. By accomplishing both neutralization and metals recovery, this process creates an economic and environmentally attractive process.
Not long after this, I was camped out with the geologist beside the Similkameen River where he showed me the evidence that an ancient channel existed on our claim.
