The famous MMM mine at Broken Hill in Australia worked the line of lode orebody and is situated within the city of Broken Hill, towards the north-east. On this 6 x 4 cm miniature, Pyromorphite crystals coat both sides of a flat plate of Coronadite, a lead-manganese oxide of matt, sooty black appearance. The Coronadite is mainly masked by the butterscotch toffee coloured Pyromorphite and a very light creamy-tan fine-grained altered sandstone. The Pyromorphite forms glassy, parallel sided prisms with a simple, flat pinacoid, the latter often a slightly lighter shade than the prism. The crystals range between 1 and 5 mm long and where they contact the Coronadite, appear a greyish graphite-tinged pale orange. The base and edges are coated with fine acicular Pyromorphite crystals of pale straw to limey lemon.

Origin: MMM Mine, Broken Hill, Yancowinna Co., New South Wales, Australia
