Feb 16, 2023 (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). The Yauro Zone is located half way between the Yuma and Auro Zones along the LP Fault 380 m to the southeast of the Yuma Zone, and 390 m to the northwest of the Auro Zone. The Yauro Zone occurs near a deflection point in the trend of the LP Fault. The LP Fault trends more northwesterly to the west of Yauro, and more east-westerly to the east of Yauro. Coarse visible gold was observed in several intervals at the Yauro Zone. DDH BR-036 returned 5.14 g/t Au over 37.4 m including up to 32.0 g/t Au over 2.65 m. DDH BR-037 returned 16.60 g/t Au over 6 m including 66.06 g/t Au over 0.5 m, 2.01 g/t Au over 66.2 m including 111.84 g/t Au over 0.5 m, and 5.60 g/t Au over 25.25 m including 59.05 g/t Au over 1.6 m (Great Bear Resources press release Oct 30, 2019).
