At the south end of Cleland Lake a medium to coarse-grained magnesite is exposed as a dip slope unit overlying a fine-grained dolomite typical of the top of the Proterozoic Mount Nelson Formation. It is exposed over the western side of a low ridge in a zone about 30 by 185 metres with a thickness of 3 to 6 metres. A chip sample across a three metre stratigraphic section of the occurrence contained 38.2 per cent MgO, 7.89 per cent CaO, 47.74 per cent CO2, 4.51 per cent SiO2 and 1 per cent Fe (total).
