All of the dark green spots on this specimen appear to be mixite. They all have a deep green color, and a loupe shows that they generally appear to be broken spheres of the mineral, revealing their radial structure. I only see one really good ball of mixite, plus a stalactitic formation in a protected cavity. There is also a larger area that appears to be aurichalcite, as it has the requisite acicular crystals and green-blue color. Additionally, there is a druze of tiny prismatic colorless quartz crystals present.
