Sluicing and Detecting Downstream
July 2020 by Matteo Oberto
…early last fall, I found my first gold-rich patch along a few crevices in the same river and found five grams of gold nuggets in one outing.
...I got the faintest of rises in the threshold. It was hardly a signal at all, and I thought it was one of the many, deep, hot rocks in the area.
Crowds may be great for football games or the Fourth of July, but not for prospecting. So, this summer, while thousands of gold seekers were heading to the coast of Alaska, I headed to a remote part of the Interior.
Over 200 panners competed in this two-day event to decide who was the best of the best.
The same questions you ask yourself about gold trapping features in the present stream can be applied to the benches above the stream. Just imagine the stream at a much earlier time, before it cut its way down to the present level…
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.
I am going to break bedrock down a bit and explain my view of the varying scenarios I come across in the field.
It is better in a gem and mineral mining operation that the driller, blaster and mucker be the same person in order to be able to predict placement of the desired mineral enriched pockets.
