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.
The first and most important thing of the sampling process is to try to be as unbiased as possible. There is a natural tendency to select rock that looks the best—even unconsciously.
...these nuggets have not traveled far from the lode because the golden wire lattices would have been torn apart or flattened during weathering of rock and deposition by violent stream action.
Not all of these slides and debris flows will produce results, but if you search for these while prospecting in your gold producing areas, then you can increase your odds of finding new gold.
We chose this particular area because an old channel had run here at one point and had been heavily worked on top of a mountain hilltop. Erosion patterns cut deeply on each side, leaving the channel exposed. The erosion cut sharply, dropping into ravines far below.
“Much of the ground where Ms. Hollingshead found her diamond is made of unweathered volcanic rock. When it rains, flowing runoff often leaves loose gravel, and sometimes diamonds, on the surface in these areas.”
An online video gave me some ideas, and with a lot of trial and error I developed a reliable method of panning free gold particles down below 35 microns quickly and easily.
