The area of the Glacier Bluff showing is underlain by volcanic rock of the Lower Jurassic Telkwa Formation (Hazelton Group) and sedimentary rock of the Middle Jurassic Smithers Formation (Hazelton Group). Stocks of the Late Cretaceous Bulkley Plutonic Suite intrude the strata.

At the Glacier occurrence, mineralization consisting of irregular lenses of galena and sphalerite is associated with quartz veining in a shear zone 1.8 metres to 2.4 metres wide. The zone, which trends north-easterly with a northwest dip, occurs in porphyritic andesite.

The Glacier Bluff vein was reported to have been relocated in 2003. The attitude of this vein is 080 azimuths, which is approximately normal to the Emerald Glacier vein system. A composite sample collected across 50 centimetres of the Glacier Bluff vein assayed 0.23 gram per tonne gold, 121 grams per tonne silver, 8.88 per cent lead and 0.73 per cent zinc (Assessment Report 27446).

A new occurrence which had not been previously reported was also located below the Glacier Bluff zone (at UTM 615030E 59456465N). A grab sample of the vein reported a trace of Au, 740 grams per tonne silver, 34.62 per cent lead, and 5.53 per cent zinc. It appears that this outcrop has been recently exposed by retreat of glacial ice and was not seen by earlier operators zinc (Assessment Report 27446).
