Here Is The Correct Way To Effectively Recognize Gold Ore
It is possible to detect gold with a specially designated metal detector. A prospecting detector can find gold as small as a half a grain. As the size of the gold becomes larger, gold nuggets can be located at deeper depths. A single grain nugget can be found at a depth of 1-2 inches.
