Exploration History

2007: Grandview Gold Inc. drilled 18 DDH totaling 4561.5 m including 1 DDH totaling 218.5 m on the new zone. 2019: Great Bear Resources resampled historic drill core and carried out drilling. 2022: Kinross Gold Corp. acquired Great Bear Resources, project name was changed to Great Bear Project. Kinross completed 225 000 m of diamond drilling and 35 000 m of reverse circulation drilling. 2023: Kinross Gold Corp. released an initial mineral resource calculation. Diamond drilling totalled 181 089 m across the LP Fault, Hinge and Limb zones and exploration targets across the project. 2024: Updated mineral resource estimate on February 14, 2024.

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). Historic drill hole DC-12-07 (drilled in 2007 by Grandview) is a 1.4 kilometre step-out to the southeast along the LP Fault from Great Bear’s Bear-Rimini discovery hole DNW-011, and was the only other hole to be drilled to-date into the footwall of the LP Fault. The final metres of DC-12-07 intersected silicified volcanic rocks visibly similar to those which yielded high-grade gold at the Bear-Rimini discovery. Lower-grade gold mineralization was also intersected higher up the hole within the LP Fault, as was also the case in the Bear-Rimini Zone. Great Bear’s geologists noted sparse fine visible gold within strongly silicified felsic volcanic rocks towards the end of DC-12-07, where they projected the Bear-Rimini Zone’s on-strike gold mineralization could occur. Past operators had recorded this interval as un-mineralized and it had not been sampled. Great Bear sampled the previously uncut core, which assayed 5.5 metres of 4.07 g/t gold beginning at 193.50 metres downhole, including 2.0 metres of 10.57 g/t gold and including 0.5 metres of 36.90 g/t gold (Great Bear Resources July 16, 2019 press release). DDH BR-005 returned 1.14 g/t Au over 22 m including 17.28 g/t Au over 0.9 m and 5.39 g/t Au over 4 m including 23.15 g/t Au over 0.5 m. DDH BR-006 returned 1.16 g/t Au over 4.8 m. DDH BR-007 returned 1.12 g/t Au over 13.0 m including 35.65 g/t Au over 0.5 m. DDH DL-03-10 returned 6.26 g/t Au over 12.5 m including 82.3 g/t Au over 0.5 m (Great Bear Resources Sept 3, 2019 press release). DDH BR-537 returned 2.2 g/t Au over 40.0 m including 18.6 g/t Au over 3.6 m. DDH BR-566 returned 2.0 g/t Au over 63.0 m including 65.4 g/t Au over 1.1 m. DDH BR-606 returned 19.0 g/t Au over 10.0 m including 33.5 g/t Au over 5.7 m Kinross Gold Corp., news release, June 28, 2022).
