Capsule Geology

The Victor occurrence area is underlain by Early Jurassic-Late Triassic Guichon Creek batholith intrusives, primarily Skeena variety coarse-grained quartz diorite and granodiorite. An Eocene hornblende plagioclase porphyry dyke is found in both fault and volcanic flow contacts to the north of the showings. In the Skeena rocks, mafic minerals are weakly chloritized and plagioclase has mild argillic alteration. The north trending, west dipping Lornex fault is approximately one kilometre to the west.

In the Victor open pit, two fault sets predominate; one striking 020 to 030 degrees and dipping moderately, the other set is younger, strikes 150 to 175 degrees and dips generally northeast. Joints have three dominant trends; two subparallel to the faults, the other striking 050 degrees and dipping 88 degrees northwest. Joint faces are coated with epidote, quartz-epidote, epidote-chlorite and chlorite.

Along the western side of the pit, quartz diorite is cut by a 30 metre wide north-northeast trending, sheared, veined and pervasively oxidized zone. Early development indicated this zone was 90 metres wide with a 022 degree strike and a moderate east dip. A quartz vein within the fault zone ranges in width from several centimetres to almost 2.5 metres and hosts disseminations of pyrite and chalcopyrite and, locally, pods of massive sulphide. The quartz vein strikes 348 degrees with a low to moderate east dip. Sericite, chlorite and carbonate alteration occurs within the fault zone as well as seams and grains of pyrite and chalcopyrite and silicified remnants of country rock.

In the present pit an oxidized gossan contains nearly barren quartz lenses, quartz-chalcopyrite veins of which some are brecciated, and quartz-carbonate veins carrying veinlets and blebs of chalcopyrite. Fractures carry malachite or azurite, and sometimes neotocite, along with iron oxides.

Two other northeast trending oxidized shear zones occur at the eastern end of the pit and are 2 and 7 metres wide respectively. The country rock is well-jointed and locally cut by a network of faults.

The mineralized zone is 150 metres long, 0.45 to 1.8 metres wide and extends downdip 100 metres. Vein reserves are estimated at 40,000 tonnes. Expected geological reserves are 100,000 tonnes grading probably 1.5 per cent copper (Geology, Exploration and Mining in British Columbia 1974).
