A lead-zinc mine discovered and first operated by Aberfoyle Ltd. It later closed and is presently being reopened by Bass Metals Ltd, along with the nearby, related, Que River mine. It is about 30km south of Waratah.
A large (16.2 million metric tons), high-grade (13.9% Zn, 7.1% Pb, 0.4% Cu, 168 g/t Ag, 2.5 g/t Au), sea-floor, mound-style, polymetallic volcanic-hosted massive sulfide (VHMS) deposit located in the Mount Read Volcanics of western Tasmania. The deposit is hosted by the Que-Hellyer Volcanics, a sequence of late Middle Cambrian mafic to felsic coherent volcanics and polymict volcaniclastics. It is mostly fine grained but chalcopyrite, galena, red-brown sphalerite, pyrite and quartz all occur in lustrous crystals to over a centimetre in vughs in both the Que River and Hellyer Mines (the latter producing attractive large galena crystals to about a centimetre in vughs. Sharp, small tennantite-tetrahedrite crystals were found on quartz crystals in the Que River mine
