Only gold at the dunes will be lost jewelry or usable Jeep parts
Wrong geology. Clark county has Silica, Gypsum, Borax, fossils, and some polishable stones like onyx, obsidian, agates. It was a sea bed so mostly minerals that formed in a shallow evaporating sea.
Best advice I have is to join one of the Gem & Mineral clubs or gold clubs. This gives you access to thier information and their Mining Claims(best part). Otherwise, trip to the BLM office to look for inactive claims, or explorable lands. If it's not BLM Land assume it is off limits unless you have permission to work private property or on someones active claim. Explorable land is evaporating too with the environmental push. Using a detector in protected areas could cost you the your finds, detector, vehicle, and possible fines. Avoid wilderness, NPS, Forestry, conservation areas, state parks, 90% of the country etc. blah blah. Always ask before you go.
you can detect in City Parks but you can not dig to uncover anything, surface finds only. Guess they like their sprinkler systems.
The closest good areas are club claims between the dam and kingman and some near pahrump. We've had a claim outside Barstow. I would like to do some work around Ely.
Good luck out there.
