There is an open pit mine near the Globe/Miami area in Arizona. There is also an Apache tears mine there. I've been to both. I don't know if they still do it, but at the Apache tears mine, many years ago, you paid a dollar and they gave you a bucket. You had to mine the rocks yourself. There are other copper mines in AZ.
Geodes can be found in AZ at the following sites: Apache Powder Plant Site near Benson, Arizona, Diamond Point and vicinity near Payson, Arizona, and Hull Mine near Yuma, Arizona.
