From the early workings in the upper levels of the Proprietary Mine, we have a plate of coronadite covered with yellow green spongy crystallised masses of bromian chlorargyrite. This is an extremely rich miniature, that displays beautifully. The Bromian chlorargyrite has been kept away from light and has retained excellent colour.
