Re: Quartz,Mica,Black Sand but no Gold. We have hot and cold rocks, the black sand, mineralized soil, white and iron stained quartz but I have yet to hit on any gold, even on bed rock but know the river has Flour Gold in it. I have though hit on very small pieces of almost flattened lead I suspect is and maybe snake shot.
Bela and Barbara Kovacs began prospecting for gold about seven years ago as a family orientated outdoors activity. A welder by trade and lured by the simple fact that beach sands can contain small bits of precious metals, Bela decided a few years ago to build a sand sucking contraption that can sift the shoreline for anything worth keeping.

Yes, it's a difficult task, especially if the gold particles are small. If there were a better extraction method, we'd be pulling gold out of seawater, but it's not practical.
Byproduct black sand from inland placering is often richer than beach sand. But generally, black sand, unless a concentrate, is not worth much effort. In any case, it is worth spending a dollar or two to have an assay made for gold of a carefully taken sample, not selected sand. The mechanical gold pan can be used for sampling test pits of sand.
Our black sand is great for testing sluices and up your panning skills. The gold and the black sand in our bags are hydraulic equivalence, meaning the gold and the black sand weight the same. The gold in this black sand is hard to pan and catch in a sluice.
