At the Grandview showing, two wide belts of north-trending quartzite form prominent ridges rising to a height of about 183 metres above the valley, in contact with chloritic phyllite and chlorite schist. Several prominent fracture sets cut the quartzite. Recent geology maps indicates this area is underlain by the lower Paleozoic Sicamous Formation (Mount Ida Group).

The principal work has been done on the steep face of the eastern belt of quartzite, at about 15 metres below the summit of the ridge. Here, an opening 1.5 by 1.5 metres extends into the cliff for 1 metre. It exposes a fracture zone striking 300 degrees and dipping 30 degrees north, and a weaker fracture system striking 290 degrees and dipping 45 degrees south. Minor fine galena and pyrite occur on the face of the old working. Narrow quartz segregations are present in the quartzite as bands 2-15 centimetres wide paralleling the 300 degrees, 30 degrees north dipping fractures.

Gold and silver values are reported to be associated with the galena and pyrite (Minister of Mines Annual Report 1928, page C211).
