The Glacier area is underlain by Upper Triassic Stuhini Group volcanic rocks. Mineralization was first described by BC Geological Survey Branch staff as result of 1988 fieldwork (Fieldwork 1988).
Mineralization is developed within a series of rusty weathering quartz-carbonate veins and veinlets cutting purple to grey andesites and amygdaloidal basalts. An east striking central vein with moderate to steep south dips (75 degrees) and average thickness of 30 centimetres, gives rise to numerous veinlets (1 to 5 centimetres wide) developed along fractures in the host rock. The veinlets extend, with decreasing abundance, up to 40 metres from the central vein. The veins also contain brecciated altered wallrock fragments commonly replaced by pyrite, arsenopyrite, chalcopyrite and mariposite. Sphalerite, arsenopyrite and chalcopyrite are found as streaks throughout the veins, commonly averaging 25 per cent of vein material. Alteration of the host rock occurs up to 4 metres from the main vein, coincident with disseminated pyrite (up to 10 per cent). Mariposite(?) is common within 1 metre of the main vein.
The quartz-carbonate veining extends at least 200 metres east until covered by permanent snow. Similar vein samples collected from talus 2 kilometres due north suggests such veining may also occur there. Non-mineralized quartz-carbonate veins have been found 5 kilometres to the west in andesites and may be related.
In its 1989 assessment report Continental Gold located its Showing 1 at the same location as the Glacier showing, first documented by the BC Geological Survey in 1988, described above. Showing 1 consists of sulphide mineralization in 10 to 15 centimetre wide veins of quartz and ankerite and consisting of up to 40 per cent pyrite and 4 per cent chalcopyrite, galena and sphalerite. One sample yielded 56 parts per billion gold, 10.3 grams per tonne silver, 0.11 per cent copper, 0.08 per cent lead and 0.04 per cent zinc (Figure 5, Assessment Report 18461).
Work History
In 1988, the Galena 1 to 4 claims were staked by United Mineral Services Ltd 1988 to cover an area of previously noted galena mineralization. During July 1985, Continental Gold Geologists spent five-man days on the property, mapping gossanous outcrops and collecting 23 rock samples for analysis.
