Nov 20, 2013 (A Wilson) - The Rio Tinto/Riocanex diamond drilling program established that the sandstone might be amenable to beneficiation to a glass-grade and foundry sand. A sample collected by the OGS in 1978 returned the following analysis: 98.86% SiO2, 0.18% Fe2O3, 0.30% Al2O3, 0.08% MgO and 0.20 CaO.
