Dec 14, 2012 (A Wilson) - A thin veneer of flat-lying Gowganda conglomerate, greywacke and argillite overlies Archean metavolcanic rocks. These rocks are underlain and intruded by gabbro (Nipissing diabase). Carbonate bodies were encountered in four of the holes drilled in 1957, and also, in the three holes drilled at an earlier date. In some sections the carbonate is medium-grained, crystalline, grey to dark bluish grey; in others it is finer grained, harder, light grey and vuggy. Occasional dark, chloritic seams of unreplaced rock indicate that the dip is fairly steep. This zone may represent a steeply dipping vein.

Dec 14, 2012 (A Wilson) - Magnetite occurs in fine grained, dark brown, fairly massive replacement bodies and banded disseminations. Narrow bands of unreplaced rock and introduced impurities indicate that the bodies dip at 65° to 70°. The magnetite bodies are believed to be roughly lenticular, with jagged outlines and the long axis trending in an easterly direction. Zones of sparsely disseminated pyrite, chalcopyrite, and pyrrhotite occur within the magnetite bodies. Minor amounts of pyrite and chalcopyrite occur also in disseminations, tiny irregular veinlets and blebs, and quartz-carbonate veinlets within the highly altered zones surrounding the magnetite deposits.
