The area immediately northwest of Mackenzie Cove is underlain by basalts and minor limestone of the Upper Triassic Karmutsen Formation. A diorite intrusion, possibly of the Jurassic San Christoval Plutonic Suite, intrudes the basalts farther to the northwest.
A pod of massive sulphide, 2 by 1.3 metres in size, outcrops in a small steeply plunging gully along a shear zone striking 160 degrees and dipping 70 degrees east. A channel sample taken over 1.3 metres assayed 1.44 per cent copper and 1.1 grams per tonne silver (Assessment Report 20330, Figure 5A, Sample D3). A pyritic zone outcrops over an area 5 by 15 metres in size, 30 metres north-northwest of the massive sulphide pod. The zone appears to continue for some distance to the southwest along a cliff face overlooking the northwest shore of Mackenzie Cove. A chip sample taken across 5 metres assayed 0.37 per cent copper (Sample D4). Another chip sample taken across 4.5 metres of gossanous outcrop assayed 1.0 per cent copper (Assessment Report 22952, Figure 3).
This showing was mapped and sampled by Doromin Resources Ltd. in 1990. The company also completed a VLF-EM and magnetometer survey along one line 170 metres long. Inco Exploration and Technical Services Inc. completed airborn electromagnetic and magnetometer surveys over the showing in 1992.
