The Black manganese oxide showing is located just south of Highway 16, approximately 36 kilometres northwest of McBride. It is about 1 kilometre west on the Goat River (Hill zone) gold-vein showing (093H 042).

The Black showing consists of MnO2 (pyrolusite) coatings on/in a buff-coloured calcareous tufa (travertine) deposit. The tufa is extremely porous and the earthy MnO2 comprises approximately 50 per cent of the volume of the rock where it was sampled. A 2.5-metre deep pit exposes the deposit and hand augering has tested the zone to a depth of 4 metres. Nearby, manganese oxide reportedly occurs cementing glacial gravels.
