When I was running AGA full time, I used to buy gold at Les Bender's office. I became friends with a fellow that was living off the grid, out by Antelope Creek. He averaged about 6-grams of gold per week, and moved a lot of buckets every day to get it. He was always desperate for gas money, and looked skinnier every month. I gave him 85-percent of spot and he was always happy to get it.
Ditch diggers make more money than most placer gold miners. Once you have the gold, then you have to sell it. It is NEVER worth what you believe it's worth. Buyers are not your friend, and will pay you as little for your gold as they can - especially in small amounts. Why not take an extended vacation in the goldfields and get a taste?
