Capsule Geology

The Jentin occurrence is located on Cedar Hill, approximately 400 metres east of Gentian Lake.

The area is underlain by Karmutsen Formation volcanic flows, pillow lavas and aquagene tuff overlain by Quatsino Formation limestone, all of the Upper Triassic Vancouver Group. These in turn are overlain by volcanic flows and breccias of the Lower Jurassic Bonanza Group. Intruding the stratigraphy is granodiorite of the Jurassic Island Plutonic Suite.

Faults and shears in altered Bonanza volcanics are mineralized with pyrite, chalcopyrite, azurite and galena. One of these faults, striking at 040 degrees and dipping at 70 degrees to the southeast, has been traced for a distance of 61 metres.

In 1982, a sample (13771) yielded 163 grams per tonne silver, greater than 1 per cent copper and zinc, respectively (Assessment Report 10866).

In 1983, a sample taken from a trench on this fault contained 0.62 grams per tonne gold, 153.26 grams per tonne silver, 9.88 per cent copper, 0.07 per cent lead and 0.07 per cent zinc; while a 45.5 kilogram bulk sample yielded 0.21 grams per tonne gold, 114.6 grams per tonne silver, 5.14 per cent copper, 0.42 per cent lead, 17.24 per cent zinc and 0.002 per cent molybdenum (Assessment Report 12637).

In 1982 and 1983, Jentin Resources completed programs geological mapping, geochemical sampling and five drill holes, totalling 654.3 metres, on the area as the Nioby claims. In 2004, Hillsborough Resources completed a ground magnetometer survey on the area as the Bog property.
