Geology Comments

Jun 20, 2013 (D Guidon) - From assessment file KL-6273 The property is located in the Burntbush Greenstone Belt ("BGB") which is situated in the northwest corner of the Achaean age Abitibi Subprovince. The BGB continues eastward in adjacent Quebec as the Harricana-Turgeon Greenstone Belt ("HTGB"). This greenstone belt hosts the Mattagami, Selbaie, Joutel and Casa-Berardi mining camps in Quebec and the Detour Lake Mine in Ontario. The HTGB/BGB trends east west and is 60-90 km wide and extends over a distance of approximately 150 km. The northern and western boundaries correspond to the Opatica granite gneiss terrain, and the Mistawak, Boivin, Mistaouac and Marest batholiths mark the southern boundary. Lacroix et ai, (1990) provide a detailed description of the geology and mineral deposits contained in the HTGB portion of the greenstone belt. In the Ontario portion of the greenstone belt, four assemblages are recognized (Jackson and Fyon, 1991). From north to south the generally east-west trending assemblages are the Noseworthy, Blakelock, Bradette and St. Laurent. The Noseworthy comprises sedimentary rocks dominated by upper greenschist facies argillaceous greywackes, mudstones, and conglomerates. The eastward extension of this assemblage probably corresponds with similar rocks located north of the Casa-Berardi deformation zone in Quebec. On the Casa-Berardi property small volumes of gold mineralization of economic interest have been located in these rocks. The Blakelock assemblage is characterized by a uniformly elevated magnetic signature and associated AEM conductors. It is interpreted to be mainly upper greenschist facies mafic volcanic rocks (tholeiites) with intercalated graphitic and sulphidic sedimentary rocks. Felsic volcanic rocks may underlie the eastern portion of the Blakelock assemblage (Johns, 1982). The Bradette assemblage consists of calc-alkalic dacitic and rhyolitic quartz phyric tuffs, lapilli tuff, pyroclastic breccia, tuff breccia and flows intercalated with graphitic sedimentary units (Johns, 1982). It is characterized by a subdued magnetic signature and numerous AEM conductors. In the eastern portion of the Bradette, a southwest-tending sinistral shear zone located near the interface between the Blakelock and Bradette assemblages is inferred on the basis deflected AEM conductors. The inferred shear zone may represent the western continuation of the Casa-Berardi deformation zone. This is plausible, as the Bradette is the probable westward continuation of the Dieppe domain in the Casa-Berardi area. The Dieppe Domain rests unconformably upon the Tiabi and Cartwright domains. Volcanic rocks of this domain are mainly tholeiites with abundant chert horizons intercalated with the pillowed basalt rocks. The St. Laurent assemblage consists of iron and magnesium-rich tholeiitic basalts and andesites, which are massive, pillowed, feldspar megacrystic or fragmental. Minor ultramafic units are also present. The assemblage is characterized by a uniformly high magnetic signature and numerous west to northwest-trending AEM conductors. This assemblage is considered to be the western extension of the sedimentary rocks found south of the "Golden Pond Sequence", a local component of the Tiabi sedimentary domain in CasaBerardi Township. All of the lithotectonic domains are intruded by north-trending Proterozoic diabase dykes. Numerous deformation zones, from 100s to 1000s of m wide, traverse the HTGB/BGB terrane, with strike dimensions in the order of lOs to 100s of kms. They are highly schistose zones characterized by a dominantly ductile deformation style. The contacts of lithotectonic domains are commonly marked by graphitic sediments and are the sites of major deformation zones, such as the Casa-Berardi deformation zone.

Lithology Comments

Jun 20, 2013 (D Guidon) - From assessment file KL-6273 The geology of the property is largely known from a synthesis of drill core geology and geophysical interpretation, as the only known bedrock outcropping occurs in the L 126W vein area. The northern part of the property is underlain by a mixed assemblage of felsic, intermediate and mafic volcanic rocks, which probably correspond to the Blacklock assemblage. Felsic tuffs predominate in the western part of this belt and mafic volcanic flows and volcaniclastics are more common in the eastern part of this belt. Iron-rich sediments as banded magnetite - silica - amphibole +/- garnets occur along the northern contact of this assemblage. Drill information suggests a steep northerly dip for the lithologies. The Spade Lake Shear Zone (SLSZ) as defined by Learn et al. (see bibliography), which also dips north, defines the southern limit of this mixed volcanic belt. The area to the south of the SLSZ is composed predominantly of mixed volcanic and volcaniclastic units of mafic to felsic composition intruded by the Spade Lake Porphyry. This assemblage probably correlates with Bradette assemblage. The Spade Lake Porphyry is a coarse grained felsic intrusion with a general granodiorite to granite composition. Shear zones and/or high strain zones of varying intensities appear to bound the porphyry body on both the north and south sides. Also contacts between the various lithologies are often high strain zones showing little lateral movement and offset. Lying to the south of this belt is another mixed volcanic assemblage composed of intermediate to mafic volcanic flows, which dip steeply north and are cut by generally east-trending shear zones, such as the L 126W vein zone. A broad area of sedimentary rocks lies south of this volcanic assemblage along the southern margin of the property.
