November 2012 by Chris RalphHeading for Australia to metal detect for gold. Tips? Suggestions?
This time we took the detectors. Roger had worked that spot very well and wanted to see if my new detector would uncover any gold he might have missed.
One 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.
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.
There is a surprising amount of detectable gold under the water’s surface. The right tools make it much easier to find, and with a little patience and practice you can take advantage of this underappreciated bonanza.
Back at the entry point of the mine, we took turns slowly crawling down the slope leading into the mine portal with our metal detectors, hard hats and flashlights. The mine was hand dug and is about 75 yards long.
The whole purpose of sampling mineralized ground is to measure the values in a small volume of material that would be representative of a much larger volume of similar material. The key word is representative. Chemical and fire assaying will not accurately represent placer deposits by themselves.
Has your experience ever led you to wonder why some gold is deposited on bedrock and in crevices, while other gold is not? We’re going take a deeper look at this and see what we can figure it out.
