The Bluenose property is underlain by rocks of the Hadrynian? to Paleozoic Eagle Bay assemblage. These comprise quartzite, marble, hornblende-rich skarn and pink to grey paragneiss. In general, bedding or gneissosity dips at low angles to the east. The rocks are highly deformed and minor tight folds are very abundant.
The Upper zone is on a relatively flat shelf above a series of high cliffs. The rock exposed along the cliffs is largely gently dipping paragneiss with sections of limy skarn and marble. The main showing is a shaft, partly collapsed and filled with water. Material on the dump is heavily mineralized with pyrrhotite and chalcopyrite, mostly in a quartz breccia. An adit, 91 metres in length, is about 61 metres vertically below the shaft and cuts paragneiss and marble dipping about 10 degrees east. Very minor pyrite and pyrrhotite are present in several patches. A second adit at the same elevation as the shaft and about 61 metres south, cuts entirely barren gneiss for 15 metres. A pit, about 91 metres south of the shaft, exposes light coloured quartz-rich marble with abundant malachite and minor chalcopyrite.
