Mining Pegmatite Deposits
July 2018 by Chris Ralph
With successively lower temperatures as the water mixture cools, new sets of minerals are formed and many of those stable at a higher degree of heat became subject to alteration as the temperature progressively moved lower.
The Alaska state government has been trying to keep up with and maybe even stay on top of the situation by studying the problems associated with rapid growth and how to solve them.
My last update on this adventure was in the April 2012 issue and involved our search for the northern extension of the Cedarberg Mine. At that time we had found it and we were in the process of returning for some detecting when Mother Nature struck with a late rain and snow storm.
Back in October I read with great interest Chris Ralph’s article on the use of a metal detector while drywashing, and I wholeheartedly agree—I wouldn’t even consider going drywashing without using a metal detector in conjunction...
These days they employ the use of metal detectors and carefully scan the shattered rocks, hoping to hear that sound we detectorists love to hear.
A week later, a small team of us hit it again, and this time the gold really showed up.
The names attached to these areas came about from many sources. Many are easy to see why the name was given while others had a more contrasting note to them.
Part I of the article addressed modern placer gold deposits. This second installment will address “ancient” flood deposits.
