Conductive Minerals and Your Metal Detector
August 2014 by Chris Ralph...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.
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.
…we cheered and high-fived each other as the ore cart slowly crested the top of the headframe, then picked up a bit of speed on the short downhill section and came to an abrupt halt, ejecting its contents of ore…
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.
With the exception of well-established operators with proven reserves and years of field experience, the high price of gold brought a flood of speculators, con men, and real estate brokers into the mix who were not previously engaged in the gold mining market.
When we last heard from Ernie, he was still in Honduras and we were anxiously waiting to hear how the set up and training went at the mine. It got a bit complicated after that.
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.
Improvements in mining equipment and techniques, along with a higher gold price, make many mining properties profitable today that may not have been in the past.
