Thought I would throw this out for you Arizona collectors. This specimen, with a matching number to label, is from the Mildren mine, which boasts 65 mineral entries (Mindat) and a wide array of diversity including buttgenbachite, matlockite, crocoite, and leadhillite not to mention copper chlorides. The mine needs some serious work. If you have been to this locality and have minerals please contact me.
