Capsule Geology

The Prident mine lies in the Zeballos gold camp, an area under- lain by a Lower Jurassic Bonanza Group Island arc sequence of basaltic to rhyolitic volcanic rocks. Conformably underlying the Bonanza rocks are limestones and limy clastics of the Quatsino and Parson Bay formations, and the tholeiitic basalts of the Karmutsen Formation, all belonging to the Upper Triassic Vancouver Group. Dioritic to granodioritic Jurassic plutons of the Zeballos intrusion phase of the Island Intrusions have intruded all older rocks. The Eocene Zeballos stock, a quartz diorite phase of the Catface Intrusions, is spatially related to the areas gold-quartz veins. Bedded rocks are predominantly northwest striking, southwest dipping, and anticlinally folded about a northwest axis.

The three principal Prident veins are hosted by the Zeballos pluton, a quartz diorite stock related to the Eocene Catface Intrusions. The quartz diorite stock is cut by several feldspar porphyry dykes. A large inclusion of granitized volcanic rock, possibly of the Bonanza Group was encountered on the 400 level of the mine for a distance of 60 metres. The three veins, dipping verti- cally and striking 040, 072 and 100 degrees respectively, follow shear zones and range up to 15 centimetres in thickness, although wider sections are present. Quartz gangue is ribboned with fine- grained pyrite and arsenopyrite. Locally, sphalerite, galena and calcite are present.

Three narrow short veins (3W, 4WA and 4W) were encountered and drifted on at the 400 and 750 levels.

Mine production of 43 tonnes in 1939 averaged 128.7 grams per tonne gold, 55.7 grams per tonne silver, 0.07 per cent copper and 0.7 per cent lead. Subsequent production is widespread with the Privateer mine (092L 008) with which the Prident Mines was connected at the 600 level. Current reserve calculations are similarly included with the Privateer mine. Indicated and inferred reserves situated both on the Prident and Privateer properties total 122,470 tonnes grading 17 grams per tonne gold (Canadian Mines Handbook 1988-89, page 333).
