All natural gold nuggets are alloyed and are NEVER pure gold. usually from 60% to 85 % gold the rest mostly silver and other metals which lowers the conductivity as compared to pure gold. I have 10 targets buried, 3 small gold jewelry ( 1 er back, 2 small stud er's) 3 small natural gold nuggets and 4 pcs of lead, foil and a small piece of a 5 cent nickle and there is no way to tell which is which with a detector
