May 2010 by Chris RalphExploration geologists looking for strategic metals projects may find open ground in some of the old historic manganese mine areas as manganese has been largely overlooked as an exploration target for many decades.
In digging the gravel, I found there were three flood layers present that were not there last winter, with about a foot of sand on top of the gravel. This was followed by eight inches or so of small rock and lots of broken granite material...
This “special” rock was much bigger and after having smashed it in half, and then in half again and again, a small gold nugget just sat there looking at me, still embedded in a small mix.
A better understanding of hard rock mining methods and knowing a little about how these mines work can help the individual prospector to understand reports and stories about both modern and historic mine operations.
