The sample is a limonitic clay with mica, jarosite and gypsum with some poorly crystallised uranium minerals. The latter probably include Uranophane-β (fibrous), Schoepite (amorphous), Compreignacite (cuboid crystals) and other minerals as a complex mixture (including Uraninite, Paraschoepite, Threadgoldite, Meta-autunite, Torbernite and Ianthinite) which require further study. From the Tasmanian United Uranium Mine, Rossarden in NE Tasmania, Australia. It measures approximately 55x45x35mm.
