Point Location Description: Drill collar of A-06-3
Location Method: Based on Assessment
Access Description: The property is located approximately 140 km north of Cochrane, Ontario and 8 km south of the former Detour Lake Mine. From Cochrane, the property is accessible by driving eastwards along highway 652 for a distance of 30 Km, then northwards for a distance of 150 Km along the Detour Lake mine access road. From the mine site, a winter road leads southeastwards and traverses the eastern area of the claim group. (T-4998)

Jun 11, 2010 (D Draper) - The property claim package extends east-west across the central section of the Lower Detour Lake Area and was named the South Detour property by Placer Dome and later the Aurora property by Conquest. It is located within the Abitibi Subprovince at the contact between the Abitibi greenstone terrain and the Migmatitic Opatika Subprovince. The property is situated on the southern flank of a synclinal fold structure that extends from the main body of the Abitibi belt in Quebec. The centre of the fold consists mostly of metasediments flanked by metavolcanics. The geological setting is in some ways similar to the Detour Lake property to the northwest in Sunday Lake Area. Thick sequences of massive to pillowed tholeiitic basalt flows contain interflow units consisting of mafic tuffs, greywackes and local chemical sediments. Gabbroic bodies and numerous feldspar porphyry and quartz-feldspar porphyry dykes intrude these sequences. Regional dynamothermal metamorphism, increasing to the west of the property, has resulted in recrystallization and deformation fabrics. Later thermal metamorphism, related to batholith intrusion on the southern edge of the claims, has locally overprinted the regional fabrics. According to the classification adopted by Winkler (1979), the rocks at South Detour would be classified as upper greenschist facies in the eastern portion of the property, to lower amphibolite facies to the west, with amphiboles being the dominant metamorphic mineral. Rocks proximal to the batholith intrusion on the southern edge of the property or the felsic intrusion to the northeast, are hornfelsed with epidote-garnet (almandine?) +I- albite being the diagnostic contact metamorphic mineral assemblage.
