OREAS 100a is one of four CRM's prepared by Ore Research & Exploration Pty Ltd from material from the Proterozoic Mt. Gee uranium prospect, Mount Painter Inlier, South Australia. The mineralisation at Mt. Gee lies within the Paralana Mineral System, host to a number of granitic and haematitic breccia bodies extending northeasterly over a distance of 11km. Mt. Gee is believed to be of hydrothermal origin and has been described as an IOCG variant.
