This specimen is packed with all sorts of goodies. The main mineral of course is one of the rarest and most coveted minerals. It is Dugganite is pearly white to light blue plates and rosettes. They are dinky little guys, but actually large relative to other Dugganites from this locality on the order of 0.3mm may 0.5mm. The two copper arrows point to them, but they are not in good focus. There are plenty of crystals scattered all over matrix, just not at the copper arrows.
Most of the green is Malachite, some of the light more translucent green is actually Bayldonite. The blue is Azurtie and crystallized in deep blue plates. The red are large tabular Hubnerite crystals to 2cm.
