A Simple Chemical Method of Tracing Mineralization Through Light Non-residual Overburden

The colour changes effected in a solution of dithizone by trace amounts of copper, lead, and zinc mineralization provide a sensitive field test for these metals. The method has been used with success by the United States Geological Survey to trace zinc orebodies under residual soils. The dithizone test is used here on samples of non-residual soil overlying a gold-bearing zone in which the gold is associated with disseminated sphalerite, galena, and chalcopyrite.
