NTS Grid: 52L01SE
Point Location Description: Outcrop
Location Method: Conversion from MDI
Access Description: GENERAL LOCATION: This deposit is located on the northwest shoreline of Wonderland Lake approximately 40 km northeast of Kenora and 15 km northwest of Jones. ACCESS: The area can be accessed by travelling north from Kenora on Highways 604 & 671 and the Lount Lake Road for approximately 60 km.
Prior to 1984 no exploration was conducted for dimension stone. 1984 M.P. Smerchanski of Winnipeg, Manitoba staked a single claim northwest of Wonderland Lake. No work recorded. 1985 L.P. Nault staked two claims northwest of Wonderland Lake. Claims transferred to P. Nault. 1986 Mystery Mountain Minerals Ltd. of Gatineau, Quebec drilled nine holes totalling 90.5 m. 1987 Nault conducted petrographic studies on the granite. Nault claims cancelled Eleven claims staked, to the east of the Nault claims, by C.B. Nelson for Nelson Granite of Vermilion Bay. 1988 to 1989 Nelson Granite conducted stripping, physical and mechanical work and removed some test blocks. Nault claims cancelled. 1994 Nelson Granite still holds the 11 claims on the northwest shore of Wonderland Lake.

Dec 07, 2005 (W Bellinger) - Beakhouse (1991) describes the geology of the area: The Winnipeg River Subprovince is a dominantly granitoid domain within the central part of the western Superior Province. The Subprovince is flanked to the south by a granite-greenstone domain (western Wabigoon Subprovince) and to the north by a metasedimentary migmatite domain (English River Subprovince) and a greenstone domain (Bird River Subprovince). Granodioritic to granitic plutons, the granitic suite, and minor dioritic to granodioritic plutons, the mafic suite, were emplaced between 2.66 and 2.71 Ga. The granitic suite is interpreted to have originated by the partial melting of the older metatonalites in tectonically thickened crust. Beakhouse (1991) goes on to describe the Lount Lake Batholith: The various phases of the Lount Lake batholith are typical of the granitic suite. The most abundant rock type is medium-grained granodiorite commonly characterized by large (less than 10 cm in diameter; usually approximately 1 to 3 cm in their longest dimension), subhedral to euhedral, perthitic microcline megacrysts. On the basis of their textures, composition and phase equilibria considerations, these megacrysts have been interpreted to be late magmatic megacrysts rather than true phenocrysts or porphyroblasts (Beakhouse 1983). Biotite is the ubiquitous and dominant mafic phase. Subordinate hornblende occurs very locally in close proximity to amphibolitic enclaves and is interpreted to be xenocrystic. Common primary accessory phases include magnetite, epidote, sphene, zircon and apatite. Secondary alteration products include white mica, epidote and carbonate (after plagioclase), and chlorite and magnetite (after biotite). JOINTING: Storey (1986) described the jointing: The vertical joint sets trend 045-060 degrees and 145-160 degrees. These are wide spaced often 10 m or more. The 060 degrees direction is the predominant set; sheeting is 0.5 to 1 m at the surface and appears to thic

Dec 07, 2005 (W Bellinger) - MINERALOGY: The stone is comprised of the following mineral constituents: 20 to 35% potassium feldspar; 45% quartz; 10 to 25% plagioclase; and 10% biotite. COLOUR: The stone is red in colour (see Photo 11, Appendix A). TEXTURE: The stone displays a porphyritic texture. OTHER FEATURES: The feldspar phenocrysts display a definite mineral lineation/preferred orientation.
