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.
The holes were overloaded with explosives, but I didn’t know it. I was just a green mining engineer fresh out of school and told to watch as the experienced miners set the charge.
Fascinated by the sapphires—and the gold that occured with them—he was soon buying parcels of property and setting up his own commercial-scale gravel processing plants.
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.
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.
Any good books on mineralized faults and contacts?
In some places, semi-continuous sections of riverbed can easily be linked in many places to identify the path of the ancient rivers.
Most prospectors understand placer mining a lot better than hard rock mining and don’t realize the amount of work that goes into processing different types of hard rock ore.
