Prospecting for Diamonds
January 2013 by Chris RalphLet’s take a look at diamonds and diamond mining and see how they form, how they are used beyond just jewelry, and what leads geologists to find diamond deposits.
It’s accepted knowledge that wet methods will recover more fine gold than dry methods and processing the gravel as a whole will get more gold than only using a metal detector. The question is how much more?
Over 200 panners competed in this two-day event to decide who was the best of the best.
We all continued over to another location at the top of a massive placer operation. Arriving at the draw, I showed everyone where gold had been found before and we all began detecting.
I believe dry washing is an underappreciated prospecting method. There are plenty of places where there is some pretty decent gold to be had, but the spot is a long way from any water and dry processing may well be the best way to go.
The call of gold is a strong one and it has pulled men from every corner of the planet. That said, I guess it’s now my turn to chase far away gold.
The biggest nugget I have found detecting here was three grams and the following weekend someone found a 9-gram nugget while detecting. Some have even found quarter-ounce nuggets, with one being a chevron nugget.
With a little homework and a methodical approach to sampling, a prospector can determine if a deposit is worthy of more of an investment...
