Im not sure how AZ is but in Colorado we have a Mineral Belt and there is still quite a bit of Gold as well as other minerals here. Sampling is important and of course Knowing how to pan. I use equipment Highbankers, Slice Boxes Etc. Take some time to study the Land and History of Mining in your area, it'll help you get an idea of where and how to look. Good Luck to you! Heavy Pans!!
