Revisiting the Rocker Box
August 2016 by Alex DolbeareThe first location we worked was a small, dry ravine cutting through many mineralized zones in an area where some hard rock mining had taken place in the past.
At the end of the day, Jerry showed me how to clean out the sluice box and then how to pan out the concentrates. As we finished panning, there it was—a little tiny smile of gold...
Chris got a nice target signal on the edge of rising bedrock, but still in a low, but washed area. After breaking up the bedrock, he recovered several pieces of gold amounting to almost three pennyweight.
While the bullion value of the nugget is already substantial, the size and rarity of the Ausrox Nugget combine to make its worth invaluable in the collector market.
The whole purpose of sampling mineralized ground is to measure the values in a small volume of material that would be representative of a much larger volume of similar material. The key word is representative. Chemical and fire assaying will not accurately represent placer deposits by themselves.
Some experienced panners with the vigor and longevity to spend a full day panning in the small creeks and ravines can possibly find as much as a gram or more on a good day.
I understand that a person without geological knowledge could be daunted reading a geological publication. You can pick out the good stuff from a geological publication without a lot of geological knowledge.
