There is host of metallics on this specimen according to the previous tag. I cannot vouch for them all, but the previuos tag states there is: magnetite, cassiterite, chalcopyrite, bornite, bismuth and wittichenite. No doubt three is magnetite. That's all I see, There are some curious looking blue crystals and some green staining.
