Hand Panning Micro-Fine Gold
May 2017 by Keith Bowen
Once you get down to the black sands or a few tablespoons of material, the technique changes dramatically.
Last month I wrote an article entitled “Good Assays and Bad,” which gathered a few comments.
Q: Can you offer any information on proper mining claim procedures?
This is the point where you might ask, “What do these types of contracts typically look like and how are they negotiated?” Well, that is the topic of this month’s article.
The excavator or backhoe has become the tool of choice for testing placer ground. These machines are the best way to explore and sample a placer deposit if the ground is not too wet or frozen and bedrock is not beyond the reach of the machine.
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.
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.
Our group of independent miners have been busy crafting a uniquely designed ladder/ore cart track from the bottom of an 85-foot mine shaft in a historical hard rock mine.
