• How small should I crush my hard rock ore?
The technique I will describe is a much safer alternative and it works. It’s a fine-gold panning technique that eliminates the need for mercury amalgamation of most placer samples.
What are the steps for filing a mining claim?
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.
Every year I go through this and every year it becomes more difficult to find new territory that is available for us to prospect. Is there anywhere that hasn’t been worked?
The first step in my recovery process after milling the ore to the desired size is to table it. On this particular ore, I get good results milling it to minus 100 mesh.
This is just the type of specimen that could have been easily ignored by the old-time miners. It felt a little heavier in my hand than a chunk of quartz of that size ought to have been.
Fortunately, there are products on the market that can address these problems and make a small-scale mining operation feasible.
