I was looking at a story about one of the biggest nuggets Ive seen a picture of when this started.Its called THE BOOT OF CORTEZ.And I thought about your comment with the metal detectors from EBAY.Well this nugget was found in SENORA WHERE ALTO IS WORKING AND FOUND WITH A METAL DETECTORthe most unusual and attractive large nugget in the World” and at 389.4 ounces Troy (32.4 Troy pounds)The story begins in 1989 in the area around Caborca, near the Gran Desierto de Altar in the Mexican state of Sonora. The nearest surface water is the Sea of Cortez; some 60 miles to the west. Arizona is 70 miles to the north. Ranching is the chief occupation, but there are a number of mines in the area along with placer gold deposits in some of the canyons. It is within these dry canyons that a local man began his quest to find hidden treasure in the form of placer nuggets. Some finds of nuggets had been made in the past, and fired with optimistic enthusiasm; our gold-seeker grew determined to find his share. At this point, our latter-day prospector did something very much at odds with tradition: visiting a Radio Shack store – he purchased a metal detector. Practicing on buried coins and other metal objects, he learned how to operate it, and then he set out for an area that was reported to have produced nuggets. http://www.coinlink.com/News/gold-silver-bullion/the-boot-of-cortez/
