Not the most beautiful specimen, but a really interesting combo specimen from a lesser-known locality with 3 different copper minerals present: azurite, antlerite (Copper Sulfate Hydroxide), which is the green mineral, and aurichalcite, the blue-green mineral towards the bottom. They have been deposited (grown, in the case of the azurite micro-crystals) in recesses in an iron-rich, limonitic matrix.
