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 DN05-04 encountered a quartz-arsenopyrite vein system from 41-47 m depth. The arsenopyrite was fine to medium grained, acicular, with trace chalcopyrite and sphalerite also present. A 7 m weighted average composite over this interval yielded 2.0 g/t Au with a maximum assay of 14.4 g/t Au over a 0.5 m interval (Assessment report 20000000851). DDH DNW-011 returned 194.21 g/t Au over 2.0 m with visible gold (53 m depth) and 30.90 g/t Au over 4.60 m (71 m depth). Drilling on 150-200 m fences continued to successfully intersect high- and low-grade gold mineralization across the 4 km strike returning results of 10.6 g/t gold over 21.0 m (BR-068), 4.2 g/t gold over 53.7 m (BR-020 and 1.0 g/t gold over 149.2 m (BR-043). The Bear-Rimini discovery is unique in that disseminated gold mineralization is hosted within silicified felsics, versus the more typical quartz-carbonate veins mineralization hosted in basalts (Adamova, 2020).
