Mineralization Comments

Oct 15, 2020 (Therese Pettigrew) - The LP Zone exhibits a style of mineralization which is not observed in other parts of the Red Lake greenstone belt. The zone is associated with a high degree of deformation, widespread alteration, and transposition of primary textures as well as complete flattening of stratigraphy. The LP Zone mineralization occurs within a wide zone of high strain and increased metamorphic grade. The strain zone is very continuous for over 4 km and is slightly oblique to stratigraphy, intersecting multiple lithologies including the porphyritic felsic volcanics, and metasediment. The deformation zone is up to 500 m wide. The higher-grade gold mineralization appears to be controlled by the intersection of this strain zone and the metasediment 2 unit. Ongoing LP Zone drilling has demonstrated that most of the greater than 5.0 g/t Au intercepts and nearly all of the greater than 10 g/t Au intercepts drilled along the LP Zone to date occur within 50 m to 100 m of the metasedimentary/felsic volcanic contact. Gangue mineralization is variable across the zone and locally ranges from 0% to any amount of the following: 1% to 15% disseminated pyrite, 1% to 10% arsenopyrite (blebby and matted), 1% to 5% red and yellow sphalerite, 1% to 5% pyrrhotite, 1% to 5% chalcopyrite, 1% to 5% galena, and 1% to 3% scheelite. The LP Zone has been further sub-divided into six sub-zones named, from northwest to southeast, Discovery, Bruma, Yuma, Yauro, Auro, and Viggo (Pfeiffer et al., 2023). DDH REG-002 returned 3.0 g/t Au over 15 m including 50.0 g/t Au over 0.75 m. Gold mineralization was present at significant changes in rock type. In particular, high-grade gold within quartz veins was best developed at the contact between a high iron tholeiitic pillow basalt and a massive basalt. The Arrow zone veins strike 280 degrees and dip steeply to the northeast. Visible gold is present. The veins at the Arrow Zone have the same high temperature red-brown hydrothermal biotite alteration that is characteristic of the Hinge zone veins at Dixie, and the High Grade Zone at the Red Lake Gold Mine.
