VANCOUVER, BC, Aug. 4, 2020 /PRNewswire/ - Great Bear Resources Ltd. (the "Company" or "Great Bear"), (TSX-V: GBR) (OTCQX: GTBAF) today reported results from its ongoing fully funded $21 million exploration program at its 100% owned flagship Dixie Project in the Red Lake district of Ontario.

Chris Taylor, President and CEO of Great Bear said, "New results from a 140 metre long previously undrilled segment within the LP Fault include 81.22 g/t gold over 10.50 metres at bedrock surface, with excellent continuity of mineralization once again observed across adjacent drill sections and to depth on the same drill section. Over the past months we have regularly intersected predictable high-grade gold intervals at the LP Fault within the broad bulk-tonnage style gold system. This positive development is underscored by both styles of mineralization extending from bedrock surface to the limits of current drilling at depth. We are currently building an updated geological model to account for the majority of this high-grade mineralization, and provide early descriptions of this work in this release."
The Company has completed 126 of approximately 300 planned drill holes into the LP Fault target, as part of its 5 kilometre long by 500 metre deep grid drill program.
Current Results Highlights
Two drill sections were completed within a previously undrilled 140 metre long gap along the LP Fault; sections 20500 and 20450. High-grade gold and wider intervals of moderate gold grades were seen in both sections. The location of drill section 20500 is provided in Figure 2. New assay results are provided in Table 1 and Figure 3, and include:
Additional drill results were returned from the same mineralized zone on drill section 20900, located 400 metres to the northwest of drill hole BR-146. Highlights include:

Figure 3: Drill section 20500 showing highlighted results from BR-143, BR-145 and BR-146. All individual assay intervals are provided from the reported shallow high-grade interval in BR-146, together with an image of visible gold mineralization from this drill hole. Images of gold mineralization are from selected intervals and are not representative of all of the gold mineralization on the property.
Table 1: Current drill results. Drill sections are arranged from southeast (top of Table) to northwest (bottom of Table).
*Widths are drill indicated core length, as insufficient drilling has been undertaken to determine true widths at this time. Average grades are calculated with un-capped gold assays, as insufficient drilling has been completed to determine capping levels for higher grade gold intercepts. Average widths are calculated using a 0.10 g/t gold cut-off grade with up to 3 m of internal dilution of zero grade.
Update on Geological Modeling
Great Bear continues to collect and interpret data to refine the geological model for the entire Dixie property. To date, the company has collected > 164,000 drill core samples and > 100,000 downhole data observations including alteration, mineralization and > 36,000 oriented structural core measurements. These data points together with ongoing cross section and 3D geological modelling continue to guide exploration drilling on the property.
While the Hinge and Dixie Limb zones are being modelled as discrete vein / replacement zones within dominantly mafic volcanic rocks, the LP Fault system consists of a broad and laterally continuous zone of disseminated gold mineralization which contains several discrete foliation parallel zones of higher grade gold mineralization with generally steeply-dipping planar geometries, hosted within both felsic-intermediate volcanic ("FV") rocks and meta-sedimentary ("MS") rocks. The "sheet-like" geometry of these zones adds to their predictability across drill sections and to depth and continues to facilitate their targeting during ongoing exploration.
The broad zone of gold mineralization at the LP Fault is associated with specific rock types, geological contacts and alteration assemblages. These rock types are recorded during core-logging and contact relationships are later refined in the 3D model once lithogeochemical data are available.
To date, two discrete high grade corridors extending to the depths of current drilling, have been identified through interpretation and re-logging of drill core from within the LP Fault:
Additional high-grade zones within the LP Fault are also being interpreted and tested with on-going drilling. Representative core photos of the Upper Vein Zone and High Strain Zone are included in Figure_4.
The Company will release a comprehensive geological and mineralization model update when current data collection and modeling work on these and other high-grade gold zones is complete.

Top: Upper Vein Zone. Bottom: High Strain Zone. Note the numerous deformed and transposed gold-bearing veins in the top image, and the relative lack of veining in the bottom image. Both intervals contain sheet-like, planar high-grade gold concentrations that have been successfully targeted within and between multiple drill sections.
Updated drill collar locations, azimuths and dips, together with an updated complete assay table for the LP Fault drilling to-date will be posted to the Company's web site at www.greatbearresources.ca. Drill collar locations, azimuths and dips for the drill holes included in this release are provided in the table below:
About the Dixie Project
The Dixie Project is 100% owned, comprised of 9,140 hectares of contiguous claims that extend over 22 kilometres, and is located approximately 25 kilometres southeast of the town of Red Lake, Ontario. The project is accessible year-round via a 15 minute drive on a paved highway which runs the length of the northern claim boundary and a network of well-maintained logging roads.
The Dixie Project hosts two principle styles of gold mineralization:
About Great Bear
Great Bear Resources Ltd. is a well-financed gold exploration company managed by a team with a track record of success in mineral exploration. Great Bear is focused in the prolific Red Lake gold district in northwest Ontario, where the company controls over 300 km2 of highly prospective tenure across 4 projects: the flagship Dixie Project (100% owned), the Pakwash Property (earning a 100% interest), the Dedee Property (earning a 100% interest), and the Sobel Property (earning a 100% interest), all of which are accessible year-round through existing roads.
QA/QC and Core Sampling Protocols
Drill core is logged and sampled in a secure core storage facility located in Red Lake Ontario. Core samples from the program are cut in half, using a diamond cutting saw, and are sent to Activation Laboratories in Ontario, an accredited mineral analysis laboratory, for analysis. All samples are analysed for gold using standard Fire Assay-AA techniques. Samples returning over 10.0 g/t gold are analysed utilizing standard Fire Assay-Gravimetric methods. Pulps from approximately 5% of the gold mineralized samples are submitted for check analysis to a second lab. Selected samples are also chosen for duplicate assay from the coarse reject of the original sample. Selected samples with visible gold are also analyzed with a standard 1 kg metallic screen fire assay. Certified gold reference standards, blanks and field duplicates are routinely inserted into the sample stream, as part of Great Bear's quality control/quality assurance program (QAQC). No QAQC issues were noted with the results reported herein.
