Prospecting Australia—Part III Anatomy of a Nugget Patch in Western Australia
December 2011 by Chris RalphOne of the most memorable nuggets I found in Australia was detected on the very last day that I was out prospecting. I was going along swinging my coil and I came across a blaring loud signal that almost blew my ears off.
Winter is the time for research, and if you haven’t already done some research to find new places to prospect, now is the time to cram in some last minute research before the good weather arrives.
The burning question I needed answered was why didn’t the deposit ever get mined of at least one of the valuable minerals? A couple of reasons have come to light.
Some media outlets have speculated the hoard of coins came from a theft at the old US Mint in San Francisco that was reported in 1901.
Some of the items that I’m going to go over are outcroppings, ditches, exploratory trenches and contacts/surface materials. I am going to speak about each of the above items in as much detail as I can, and then towards the end of this article I will tie them together.
In some places valuable ores can be found within the waste material of mine dumps, sorted ore piles, and detrital vein matter at the surface. Though many of these old mine sites can be an excellent source of gold, not all are created equal.
Plumas has been historically rich in gold because of its favorable geology. The Melones Fault trends north-south through the county and many rich gold-bearing districts lie along its course.
As I laid in my Jeep and tried to get some rest, I began to realize how tired I was. I felt like a little kid who walked around Disneyland for 12 hours with his parents.
