Great Bear has completed a model-driven geological review of the Red Lake District, Ontario, using the geological and geophysical signature of the Dixie Project’s D2 fold and deep-seated structural gold controls as guides, the Company has identified several targets on regional properties described below. Further exploration of these properties is planned and will continue through 2021.
The Sobel Property is a 3,200-hectare property located along the interpreted strike extension of the main D2 fold axis which is a control for gold mineralization at Evolution Mining’s Red Lake Gold Mine. Historical exploration work completed on the Sobel Property includes drilling, ground and airborne geophysics, rock and soil geochemistry, and mapping. To date, Great Bear has identified prospective rock types and contacts, including komatiitic basalt and strongly altered iron formation at the contact of two basalts. A Spatiotemporal Gas Hydrocarbon (“SGH”) survey completed in 2020 identified two areas on the property that are prospective for gold. The same SGH technique was used by Great Bear to successfully define the locations of subsurface gold mineralization at the Dixie Project, and hence the SGH targets at the Sobel property are viewed by the Company as highly prospective. One of these targets is along strike of the mineralized iron formation described above and coincides with an interpreted regional D2 fold axial trace. A prospecting and mapping program was completed during the 2021 field season. Crews collected 249 surface samples to be analyzed for gold and 4-acid digestion ICP. During this program, new outcrops were identified and 115 structural measurements were collected to further our geologic understanding of the property. This data will be used to refine and identify new drill targets on the Sobel property.
The Pakwash Property is a 3,100-hectare property which contains rocks within the complex Pakwash Fault Corridor which is located southeast of the Dixie Project and covers portions of a major regional fault structure lying along English River sediments. Historical exploration work completed on the Pakwash Property includes mapping, airborne geophysics, and Mobile Metal Ion (“MMI”) soil sampling. To date, Great Bear has identified a potential gold zone near the contact of the Pakwash intrusion and the host gneiss assemblage through mapping, prospecting, and the completion of an SGH survey. A mapping and prospecting program was completed during the 2021 field season. During this program, 68 samples were collected to be analyzed for gold and 4-acid digestion ICP, including 20 samples from within or near the contact to the Pakwash intrusion. Data from these outcrops will assist in drill targeting designed to test this contact.
Red Lake North Property
The Red Lake North Property is a 3,220- hectare property which is located in what are interpreted to be the Woman Lake and Flat Lake assemblages of the Balmer Sequence, approximately 70 kilometres northeast of Red Lake. The Red Lake North Property hosts local D2 fold culminations which are important controls of gold mineralization elsewhere in the Red Lake area and contain several gold-in-quartz vein type historical showings, including limited historical drilling. Third party logging activities are planned for 2021-2022 that will provide road access to the Red Lake North Property for the first time, facilitating low-cost exploration. In June 2021, field crews accessed the site and identified multiple new logging roads and cut blocks. Within these newly exposed areas, several samples were taken of felsic volcanic outcrops, indicating geology similar to the host rocks of the LP Fault on the Dixie Project. During the 2021 field season, an extensive mapping and prospecting program was completed. 581 samples were collected from outcrop to be analyzed for gold and 4 acid digestion ICP. Prospective felsic volcanic and felsic fragmental outcrops were identified in numerous outcrop exposures throughout the property. 229 structural measurements were taken to improve the geologic understanding of the property. Due to access limitations, the Red Lake North Property has seen very little historical exploration compared to surrounding properties.
