This is an example of a rare phenomenon at Bisbee: mine timbers from the very old works that, over time, stalactitic, botryoidal aragonite formed on - which in turn got a pretty green color from copper staining. Once this was considered a cuprian aragonite variety called locally "brucksite." Ex. Mullane Collection.
