    Firstly, the gold is found in such small quantities ppm in slurry samples, and has a very high specific gravity of 19.3g/cm 3. In addition, the gold particles are extremely fine, with measurements of typically less than 20 m in many instances. Gold will easily segregate and find any opening or crack available to settle and elude detection.
