Exploration History

Prior to 1987 no exploration for dimension stone had been conducted. 1987: Claims stake by C.B. Nelson for Nelson Granite. B.R. Crowley staked 6 claims and transferred them to T. Coppola of Canital Granite. 1988: Canital Granite removed some test blocks from the site. Nelson Granite conducted power stripping and mechanical work including removal of some test blocks. C. Wrazej staked a single claim west of Red Deer Lake. Transferred claim to A.T. Palin. 1989 to 1991: Nelson Granite continued to work on their property. T. Coppola transferred all interest to Manex Granit Inc. Manex continued working on the property. A.T. Palin conducted geophysical and geological surveys. A.T. Palin transferred claim to Palin Granite Canada Inc. No further work conducted, claim cancelled. 1994: Nelson Granite and Canital Granite continue to hold claims north and west of Red Deer Lake. From 1996 to 2000 Nelson Granite produced 4851 cubic metres of stone quoted from Kenora ROAs. 2022: Nelson Granite holds an aggregate permit on the quarry.

Geology Comments

Dec 07, 2005 (Peter Hinz) - The property is underlain by rocks of the Lount Lake batholith, part of the Winnipeg River supbrovince (WRS). Beakhouse (1991) provides the following descriptions, (quote) The WRS is a dominantly granitoid domain within the central part of the western Superior Province. 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. The various phases of the Lount Lake batholith are typical of the granitic suite. (unquote).

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).

Dec 07, 2005 (W Bellinger) - The stone is composed of pink potassium feldspar phenocrysts in a fine- to medium-grained matrix of potassium and plagioclase feldspars, quartz and biotite. JOINTING: Kennedy and Sherlock (1988) described the jointing: The granite formation is very massive with few, widely spaced, vertical fractures. Sheeting or horizontal fracturing is spaced from 1 to 5 m and greater allowing for extraction of very large blocks. COLOUR: The stone is reddish-brown in colour TEXTURE: The stone displays a coarse-grained and porphyritic texture. The stone is marketed as “Red Deer Brown” or “Canadian Mahogany”.
