I haven't tried it, but I have tried on a tributary to the Salt Rivier, Sycamore Creek. I have been trying to find some place that is reasonably close that might be worth spending more time at, but so far I think the Bradshaws are best bet. When I was up at Sycamore Creek, I got a lot of trash, shell casings, aluminum cans, etc., I did find one very small flec of gold, so small I needed a magnifying glass to spot it. So my theory on what you would get on the Salt River would be a bunch of trash and if you did find gold, it would probably be similar to what I found at Sycamore. The thing is, gold is not going to occur very frequently the farther away you get from the actual source of it, and the farther away you get, the more likely it will be in smaller pieces. And the closer you are to a populated area or frequently visited spot, the more trash you will find. I'm planning on going to the Bradshaws this weekend; but in the future, I would like to try to get down to the Arivaca area, because I think that might be a good place to MD.
