"The Cheechoo property (Sirios Resources) is located in the Eeyou Istchee Baie-James municipality, 15 km southeast of the Éléonore mine. The study of the Cheechoo property is an opportunity to unravel a new style of gold mineralization in the Éléonore area and the potential influence of magmatism on gold mineralization. This report focuses on detailed mapping conducted on the main stripping area and the 6-9 trench of the Cheechoo property. The regional setting of the deposit is briefly presented in order to provide a framework for trench descriptions. Geological maps of stripped outcrops are presented and discussed with an emphasis on structural features and timing relationships with the auriferous vein network. Lithogeochemical features of the intrusion are also discussed and compared to similar intrusions in the area. The vein network, hydrothermal alteration and their geochemical footprints are also described, using macroscopic and petrographic observations, mass balance calculations and the sulfur isotope composition of gold-associated sulphides. Finally, structural controls of the auriferous vein network, geochemical features of the intrusion and analogies with similar gold mineralization are discussed"--Introd., p. 3, 4.
