Sampling, Hydro-Shocking & Cleaning Quartz-Gold Specimens
May 2017 by Reese Townes
Many specimens have a small amount of gold and are not pretty to look at. There is a nifty way to give them a makeover and make them much prettier than they were when you found them.
The technology used in these devices has advanced greatly in the last century. Many different types of physical effects are used to measure these magnetic fields and we will briefly look at some of these.
I’ve been following the precious metals for decades, and I haven’t seen a move this powerful in many years.
The zone of influence of each sample must be carefully considered when deciding how far sample sites should be spaced from each other.
There is a material processing principle widely used in large milling operations to improve recovery that is poorly understood by most of the micro-mining and prospecting community...
I will make the assumption that when any of you take a detector in your hand and head out prospecting for gold you are probably anticipating finding some gold. That’s the general idea, right?
The anticipation of finding out if the system of snatch blocks, shackles, chokers, anchor points, and the strap binding the massive slab of rock in the bottom of the river would even budge an inch was weighing on me.
I understand that a person without geological knowledge could be daunted reading a geological publication. You can pick out the good stuff from a geological publication without a lot of geological knowledge.
