The elongated crystals coated with Quartz are supposedly Quartz pseudomorphs of Enargite. I'm not sure of that since I have never seen such long acicular crystals of Enargite with that width to length ratio. But there is yellow micro crystals of Beudantite and beads of Malachite, which actually could be Xocomecatlite. There are also numerous Baryte crystals. Ex. Excalibur-Cureton Company.
