Simple Mine Surveying With Basic Hand Tools
April 2021 by Keith Bowen
…there is an easy way to create a reasonably accurate map without any fancy instruments.
There are a few questions you will need to ask yourself before you apply for a suction dredge permit from the State Water Resources Control Board.
The small-scale miner has reasonable opportunity to exploit some of these small, rich placer gold deposits.
Over the years, I've noticed a pattern in the type of rocks associated with the best gold deposits in Midwestern glacial gravel.
...most prospectors don't even think about the conductivity of minerals, but there are some that do conduct electricity to a certain degree, so metal detectors will respond to them.
Unfortunately, not all the gold that we prospectors find is pretty, or appealing to the eyes. They are not all nice, bright, shiny nuggets with lots of character that carry high collector value.
Before I tell you what dredging backwards is, I’ll tell you why my team and I decided to give this very unconventional dredging method a try.
I thought it might be worthwhile to take a look at the basics of this important mineral separation technique and how a miner can use it to recover the values out of an ore.
