My wife and I lode mine for gold, turquoise in SE Arizona. We have a small crusher and pulverizer for free mill gold. Sulphides I sell to a processor if the ore proves cost effective. The Underground gold mine was mined heavily in the 30's for gold and silver. The Underground turquoise mine belongs to a friend and we mine as needed for a percentage. We enjoy both placer and lode mining and are fortunate to be able to do both. I have open pit and underground lode mined in Arizona, Alaska, Montana, Nevada, Wyoming for copper, gold and coal, and in Ghana and Maurtania Africa. for gold.
