Capsule Geology

The Ruth & Francis occurrence is located along the north fork of Glacier Creek, 9 kilometres northeast of Stewart. A vein containing antimony-bearing massive sulphides has been explored in this area since 1906.

The showing is hosted in north striking, west dipping argillite, siltstone and greywacke of the Middle Jurassic Salmon River Formation (Hazelton Group). These sediments are intruded by numerous felsic and augite porphyritic dikes.

The mineralization is confined to several veins and a shear zone. The Main vein is a quartz breccia vein hosted in argillite which occurs on the west side of a vertical fault that strikes 030 degrees. The vein strikes 010 to 040 degrees for at least 46 metres, dips vertically and is 0.6 to 2.1 metres wide. Mineralization consists of massive to disseminated pyrite, sphalerite, jamesonite, boulangerite and minor chalcopyrite, tetrahedrite and galena. A chip sample along a 1.98 metre long, 0.6 metre wide zone of massive sulphides assayed 0.66 gram per tonne gold, 1083 grams per tonne silver, 15 per cent lead, 18 per cent zinc and 8.3 per cent antimony (Minister of Mines Annual Report 1918, page 77).

The Cross vein strikes 120 degrees, dips 72 degrees south and intersects the Main vein. This quartz breccia vein is 1.2 metres wide and is developed along the south side of an adjacent, parallel dike. Anomalous copper and gold assays are reported from this vein (Minister of Mines Annual Report 1914, page 156).

A shear zone, 100 metres long and 1.2 to 3 metres wide, lies 300 metres east of the two veins. The zone contains chalcopyrite in a gangue of quartz and calcite.

In 1918, a tunnel on the Ruth claim has been driven 9.4 metres following the hangingwall of the vein striking 040 degrees then turns to the left on a bearing of 010 degrees for 9.1 metres to the face following the footwall. About 61 metres farther south and 18 metres vertically lower, another tunnel has been driven 7.6 metres on the same vein. In 2006, Teuton Resources Corp. completed 228.1 line-kilometres of a helicopter-borne AeroTEM II electromagentic and magnetic survey on their Silver Bell property which covers the showing area.
