How to Make a Rock Sled for Dredging
August 2017 by Ron Kliewer
When my “anonymous” friend told me the rock tub was probably a hundred miles from where he safely stashed it, I decided to build another sled and improve on my old design.
Small-Scale Hard Rock Production
So far this year we have recovered over three pounds of gold and the hard rock veins seem to go on forever. We now have three claims that can produce good enough gold to set up a productive operation.
Gold Geochemistry: Where Does Gold Come From?
Prospectors often wonder why gold deposits in veins like it does. Why is one vein rich while another is barren, even though they are only a few hundred feet apart?

Nice Specimen Gold Recovered in Northern California
Each specimen is carefully examined to determine if it would be beneficial or not to use an acid treatment to reveal more of the gold.
Underground Mining: Stoping Methods
In an old mine that does not have stopes, you know the old miners did not take much if any ore out of that excavation. On the other hand, if you see large stopes within the mine you know that it is these places where the miners found profitable ore deposits within the vein.
To Foam or Not to Foam
George was considering filling his dredge floats with closed-cell foam, ensuring that there would be no area available within each float for flooding.
