For sale is a large sphalerite with ferroan-magnasite, from Mount Bischoff, Waratah, Tas. Sitting at the top is a large area of bladed tan magnasite , with a scattering of small white calcite crystals. This very old specimen, then features a large area of glossy black sphalerite, small areas having crystal form the rest is massive. The sphalerite is spread thru a thick band of quartz, with minor chalcopryite. Such a large display area of sphalerite is from my knowledge uncommon from this locality.
