Greetings. I am hoping to get advice on what is the best equipment to use to locate gold items at the bottom of a huaca. The huaca is an average of 3 meters deep. The gold items were placed(typically)in a dinner plate pattern. The soil is the most heavily mineralized in the world. Volcanic. Iron and copper deposits galore. The makers of the huaca did not use ladders or ropes. They used ramps. Any advice?
Regards
