It’s worthwhile for the prospector using a metal detector to know a little bit more about the association of iron and gold as well as how iron minerals affect your metal detector.

A Wilfley table works best when all of the mineral being run across it (the pulp) is about the same size. For this reason, I took a good look at each of the samples.
Digging in the right spots will produce excellent results, like this group of nuggets taken by the author while metal detecting during the last few months. The biggest nugget is over an ounce.
