Gold and silver do not ionize and magnetize or decay over time This is the inherent property of pure gold and silver which has a positive electrostatic field current with electromagnetic fields and other fields do not disrupt the pure gold and silver field This is one of the reasons why gold and silver remain intact underground over time and do not ionize and magnetize
Any type of detector or metal detector or any type of system as a detector must detect the gold field and various metals separately at depth and separate and discriminate to prove that the circuit and settings and design of its circuit are the detector of metals and gold and silver fields at depth and are reliable
