Capsule Geology

The Jane vein occurs in a zone of strongly foliated tuffs of the Lower Jurassic Telkwa Formation (Hazelton Group). The vein is 30 to 130 centimetres wide and trends northwest dipping north, with a narrow zone of sericite alteration along its margins. Variable amounts of sulphides are present including shattered pyrite and chalcopyrite. In 1922, a test sample of 100 lbs. taken over 0.6 metre assayed 148.8 grams per tonne gold, 358.6 grams silver and 4.6 per cent copper. Assays in 1984, over 1.5 metres give 68.6 grams per tonne gold and 140.6 grams per tonne silver.

Ore was mined from the Chisholm vein, located southeast of the Jane vein. In 1918, 12.7 tonnes of ore produced 82.28 grams per tonne gold.

In 1986, a grab sample from the Dome vein, located on the Dome 4 claim approximately 1.0 kilometre northwest of the Jane vein, assayed 4.11 grams per tonne gold. Trace barite is associated with the quartz veining.

WORK HISTORY

In 1985, Teeshin Resources Ltd followed up on Noranda's geochemical/geological program with 3 to 4 holes on the Jane vein zone, intersecting a number of narrow high grade veins on the Chisholm-Jane Vein zones. In 2000, Guardsmen Resources collected soil samples over the Jane showing grid and, along with a number of other showings, collected rock samples. Sampling in 2000 from a northwest-trending quartz-sulphide vein in the Jane Adit assayed up to 48.5 grams per tonne gold along with associated high bismuth, antimony, zinc and cadmium (Assessment Report 26532). Sampling of a northwest-trending quartz-sulphide vein from the Chisholm shaft (extension of the Jane vein) assayed up to 32.3 grams per tonne gold with associated high molybdenum and copper and moderated silver, bismuth, manganese and iron (Assessment Report 26532).

Refer to Dome Mountain (Boulder vein) (093L 276) for related details and a complete Dome Mountain property work history.
