Fine gold in blonde beach sand. - GOLD

A pretty common mis-interpretation when looking at mica flakes in a half concentrated pan. The good news is that heavy mica is a great source of rare earth elements. It might not be gold but you could have

Mica, Mica in the Sand, Tell Us Something Really

25/08/2019  Researchers have found that mica grains are quite abundant on the beaches along the coast of the African nation of Namibia. The ocean has carried this sand northward along the coast for hundreds of miles, but the mica survived the entire way despite the chaotic surf. But guess what? Strong winds have picked up some of the sand and carried it inland to the massive dunes of the Namibian

02/07/2012  As the mercury goes around the pan it will pick up all the finest gold in the pan. The more gold there is the stiffer the mercury becomes. Once you have all the gold gathered, pan or suck off the sands (or use a magnet in a plastic baggie to retrieve black sands), leaving only the gold laden mercury and free mercury. The free mercury will roll around easily where the gold laden mercury is stiff and does not toll well. Place your mercury container INSIDE another gold
