Dec 07, 2005 (W Bellinger) - Hinz and Lucas (1992) described the general geology: The area is underlain by rocks of the Winnipeg River (to the south), the English River (the centre) and Uchi Lake (to the north) subprovinces. The Winnipeg River Subprovince is composed of granitic intrusives and gneissic domes. The English River Subprovince consists of primarily metasedimentary migmatitic rocks. The Uchi Subprovince contains metasedimentary and metavolcanic belts with gneissic-intrusive complexes between the belts.

Dec 07, 2005 (W Bellinger) - The mineral constituents are orthoclase (35%), plagioclase (35%), quartz (30%), biotite (3%) with minor muscovite (1%). JOINTING: Jointing observed during mapping was widespaced and had the following orientations: 008 degrees; 022 to 036 degrees; 080 to 090 degrees; and 131 degrees. Over a two kilometre section, only eleven joints were recorded (Figure 6). Sheet jointing was noted at three locations. The sheets are between 0.5 to 1.5 m wide. COLOUR: Outcrops display a light grey colour. When polished the stone is a light grey (see Photo 4, Appendix A). TEXTURE: The stone is medium to coarse grained in texture.
