Great Bear Resources Ltd. (TSX-V: GBR) today reported multiple gold discoveries along 3.2 kilometres strike length of the approximately 18 kilometre long LP Fault target at its 100% owned Dixie project in the Red Lake district of Ontario. Highlights of the new drill results include:
Chris Taylor, President and CEO of Great Bear said, “Our first month of reconnaissance drilling along the LP Fault has been highly successful. To place the scope of our program in context, the combined strike length of significant mine properties in the Red Lake district from the Starratt-Olsen deposit in the southwest, through the central Red Lake Mine Complex, to the Phoenix deposit in the North, is approximately 23 kilometres. This is roughly the same as the strike length as the LP Fault target at Dixie. While the total extent of gold mineralization along the LP Fault is unknown, we have now confirmed gold in all drill holes that intersected the fault along 3.2 kilometres, and will continue aggressive step-out and step-down drilling until we find the system’s limits. We plan to have drilled along most of the LP structure by this time next year, and, are already fully funded for this work.”
John Robins, Advisor to Great Bear said, “Great Bear’s recent discoveries south of Red Lake appear to have the hallmarks of an emerging district-scale gold camp.”
A key observation from recent drilling along the LP Fault is that the alteration zone within sedimentary and felsic volcanic rocks which hosts disseminated gold mineralization attains significant widths of up to up to 300 metres of core length where drilled to-date. The mineralized system continues from the near-surface to over 500 metres depth (the extent of current drilling), and is open to extension. This is shown on the drill sections in this news release.
Gold-bearing zones are in turn surrounded by broad halos of typically barren sericite alteration. This is also observed at other major Archean greenstone mesothermal/structural gold camps across Canada.
The LP Fault gold mineralization system is clearly not typical of the Red Lake district. High-grade gold in quartz veins, hosted by mafic volcanic units characterizes most of the major gold deposits in Red Lake, and is also observed at Great Bear’s Hinge and Dixie Limb gold discoveries, located less than one kilometre from the LP Fault.
New Auro Zone Discovery: Section 20075
Table 1: Assay intervals from Auro Zone discovery hole BR-020.
*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 in the Auro Zone to determine capping levels for higher grade gold intercepts. Average widths are calculated using a 0.10 g/t gold cut-off grade with < 3 m of internal dilution of zero grade.
New Yuma Zone Discoveries: Section 20950

New Bear-Rimini Discoveries: Sections 22375 and 22325
Whole rock (XRF) analysis provided a multi-element dataset that also helped identify key felsic stratigraphic sequences which are the preferred host rocks for gold mineralization along the LP Fault. These rocks are chemically and visually distinct, and together with oriented core data and 3D magnetic susceptibility modelling, the Company is successfully targeting higher grade zones within the mineralized envelopes.
Drilling at the Bear-Rimini Discovery Zone is currently too shallow to adequately test plunge models for high grade zones, and will be extended both along strike and depth as the drill program proceeds.

Great Bear continues to undertake a fully funded, 90,000 metre drill program that is expected to continue through 2019 and 2020. Targets tested will include the Hinge Zone, Dixie Limb Zone, Bear-Rimini Zone, Yuma Zone, Auro Zone, LP Fault, North Fault, and other targets across the property. In order to accelerate the program, a second drill rig was added in February, and a third drill rig arrived in June of 2019. Approximately 40,000 metres of drilling remain in the current program.
About Great Bear
Great Bear Resources Ltd. is a well-financed company based in Vancouver, Canada, managed by a team with a track record of success in the mineral exploration sector. Great Bear holds a 100% interest, royalty free, in its flagship Dixie property, which is road accessible year-round via Highway 105, a 15 minute drive from downtown Red Lake, Ontario. The Red Lake mining district is one of the premier mining districts in Canada, benefitting from major active mining operations including the Red Lake Gold Mine of Newmont Goldcorp Corp., plus modern infrastructure and a skilled workforce. Production from the Red Lake district does not necessarily reflect the mineralization that may, or may not be hosted on the Company’s Dixie property. The Dixie property covers a drill and geophysically defined multi kilometre gold mineralized structure similar to that associated with other producing gold mines in the district. In addition, Great Bear is also earning a 100% royalty-free interest in the Pakwash, Dedee and Sobel properties, which cover regionally significant gold-controlling structures and prospective geology. All of Great Bear’s Red Lake projects are accessible year-round through existing roads.
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 SGS Canada Inc. in Red Lake, Ontario, and Activation Laboratories in Ontario, both of which are accredited mineral analysis laboratories, 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. No QAQC issues were noted with the results reported herein.
Mr. R. Bob Singh, P.Geo, Director and VP Exploration, and Ms. Andrea Diakow P.Geo, Exploration Manager for Great Bear are the Qualified Persons as defined by National Instrument 43-101 responsible for the accuracy of technical information contained in this news release.
