The Miner’s Switchback
May 2018 by Bilbo Kringle
Common thought is the switchback slows the velocity of the rushing water and gold drops out from the cut bank to a fill gravel bar within or below the switchback. I am not going to disregard that model; however, I hope to improve upon it.
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.
Even though they have put down thousands of dollars, the buyers often stop paying on their claims part way through the process after they realize they’ve been duped, but the company just sells it again to another buyer.
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.
Historically, Montana has been an important gold producer, in terms of both lodes and placers, and it still produces gold for the prospector today.
Each specimen is carefully examined to determine if it would be beneficial or not to use an acid treatment to reveal more of the gold.
