Capsule Geology

The Red 2 occurrence is situated at the headwaters of Glacier Creek near the extensive Cambria Icefield, about 8 kilometres northeast of Stewart. The Blue Grouse showing (103P 224) is about 780 metres south.

The underlying geology consists of Middle-Upper Jurassic Salmon River Formation (Hazelton Group) clastic rocks and Lower Jurassic Unuk River Formation (Hazelton Group) volcanic rocks. These are intruded by fine grained granodiorite dikes/sills and/or small plutons. The sediments consist of a thick sequence of laminated to thickly bedded silty mudstone, siltstone, argillite and fine to coarse-grained sandstone. Included in the sequence are pebble conglomerates and massive tuffaceous mudstones. The volcanic rocks consist of interbedded basaltic flows, argillites and minor limestone. The basaltic rocks are fine grained and chloritic. The argillites are very fissile, locally sericite altered with occasional bright yellow weathering stain along bedding features. Sericite altered zones are usually 1-2 metres wide with 1-2 per cent pyrite as fine grained, disseminated grains or as fracture fillings. Limestone horizons are narrow and discontinuous zones along the contact with basaltic rocks. Where observed, the intrusive rocks consist of fine grained granodiorite dikes, some up to 10 metres in width. Locally, the intrusion is silicified with wide but discontinuous zones of quartz veinlets that comprise up to 50-60 per cent of the intrusion.

A large zone of quartz veins, veinlets and stockworks is present over a width of 20 metres. Blocks of limestone and argillite, breccia and massive pyrite veinlets are also present along the zone which strikes at 310 degrees and dips at low angles to the west. It is speculated that this zone lies along a major thrust plane. The fault zone is easily identified over a strike length of 300-400 metres and contains about 15-20 per cent quartz overall as fairly widely spaced stringers. Minor chalcopyrite occurs sporadically in some of the quartz. Locally brecciated argillite is cemented with quartz containing coarse pyrite in amounts up to 15 per cent of the breccia. In addition, massive pyrite veinlets occur within weakly brecciated argillite along the fault. At the contact of the limestone and underlying basalt, coarse pyrite occurs as massive bands from 1-6 centimetres thick, conformable to bedding, over a width of several metres. Pyrite content is locally almost 75 per cent over short exposed distances.

A later shear striking at 338 degrees has offset the quartz stockwork and breccia zone by 4 metres vertically. This narrow shear contains massive galena, sphalerite, tetrahedrite, chalcopyrite and pyrite as pods, lenses and stringers. The shear is only exposed over a length of 20 metres and maximum width may be up to a metre. It also appears to offset the massive banded pyrite by a distance of several metres. A grab sample (ERK-879) from a blasthole from this area analysed 176.3 grams per tonne silver, 0.54 per cent copper, 3.58 per cent lead, 24.6 per cent zinc and 0.18 gram per tonne gold (Assessment Report 23853).

Approximately 300 metres to the northeast, another fault is indicated. This one is up to 4 metres wide, striking 010 degrees and steeply dipping, consisting of graphitic gouge with a barren quartz-calcite veinlet stockwork. A short distance south of the second fault, a quartz-carbonate zone 3-4 metres wide occurs over a length of 30-40 metres. This zone contains locally abundant pyrite, minor chalcopyrite and associated malachite stain. Sulphide content varies from 3-6 per cent with chalcopyrite rarely greater than 1 per cent. In the vicinity of the zone, very fine grained, discontinuous massive pyrite veinlets occupy shears as 15-30 centimetre wide stringers, trending at 025 degrees. East of the above faults, along the glacier edge, numerous, narrow discontinuous quartz-carbonate zones are present, some containing sparse chalcopyrite. In addition, pyritic zones are present in the argillites, particularly along the contact with granodiorite dikes. Disseminated and fracture filling pyrite may form up to 5-7 per cent of the rock.

In 1994, Teuton Resources Corp. collected 59 reconnaissance rock samples for analyses. Some minor blast trenching was also carried out as an adjunct to the geochemical sampling program.
