The property is underlain by Upper Triassic Karmutsen Formation (Vancouver Group) basaltic volcanics overlain by Upper Triassic Sadler Formation limestone. The Karmutsen rocks are interbedded with lenses of limestone and minor argillite. A variety of felsic volcanics occur throughout the area intercalated with Karmutsen mafic volcanics. These felsic rocks may be related to the Karmutsen eruptions or may be later intrusions. A granodiorite to tonalitic pluton, probably related to the Middle Jurassic San Christoval Plutonic Suite, intrudes the strata. The Karmutsen volcanics in this area strike northwest and dip shallowly southwest.
Two major fracture orientations dominate both topography and distribution of alteration and mineralization. A major fault system extends from Buck Point, southeast for 40 kilometres to the head of Peel Inlet, and a major northeast trending fracture zone controls silicification in the area.
Zone B, or the Saddle Zone, is located on the topographic saddle along the ridge south of Kitgoro Creek. This northeast trending zone is at least 600 metres long, 150 metres wide and is found along the southern contact of the granodiorite body. The zone is characterized by silicification, quartz veining and disseminated pyrite. The host rocks are felsic volcanics with minor interlayered Karmutsen mafic volcanics.
Rock samples contained up to 0.65 grams per tonne gold (Assessment Report 8519). Three holes drilled in 1981 by Canadian Nickel Ltd. (Inco) failed to intersect rock with significant amounts of gold.
The D Zone occurs along the north margin of the granodiorite stock about 140 metres northwest of the B Zone. This silicified zone occurs in similar rock as the B Zone and samples contained up to 0.61 grams per tonne gold (Assessment Report 8519).
