And my theory is that the GOLD as much stronger electric emissions than other metals. The Gold acumulate much more energy ,but other metals acumulate and irradiate less energy.

I have my doubts... As gold corrode (no corrode, except "low gold") less than other metals as bronze or copper, is more difficult to be detectable at distance, except if you can build device with high selectivity. Except treasure size or cache, small gold items are reluctance... Bronze and copper and even silver coins not pure (mixed with copper) are more "ease". With absorptive method found a silver 1797 Spanish coin (some "black" for the time), but just five times can be detected and fix the site. No more than 4 meters and depth 20 cm.
