Great Bear Drills Multiple Shallow High-Grade Gold Intercepts at LP Fault Including 16.56 g/t Gold Over 11.00 m; Provides Higher-Density Drill Results and Updated Drill Sections
January 13, 2021 – Vancouver, British Columbia, Canada – Great Bear Resources Ltd. (the "Company" or "Great Bear", TSX-V: GBR; OTCQX: GTBAF) today reported results from its ongoing $25 million fully funded 2021 exploration program at its 100% owned flagship Dixie Project in the Red Lake district of Ontario.
This news release provides results from 22 additional LP Fault drill holes over 1.2 kilometres of strike length on 13 drill sections. Great Bear has now published results from 220 LP Fault drill holes and anticipates up to 400 LP Fault drill holes will be completed by the end of 2021. Figure 1 and Table 1.
The Company also provides new, detailed drill sections in this release, informed by higher-density drilling. Figure 3, Figure 4 and Figure 5.
Chris Taylor, President and CEO of Great Bear said, “We recently drilled a test panel of 15 densely spaced holes on 25 – 50 metre centres along 100 metres of strike length at the LP Fault to a depth of over 450 vertical metres. We were very pleased to observe the same continuity of high-grade and bulk tonnage gold mineralization at the finer scale as we had previously seen with more widely spaced drilling.”
Shallow High-Grade Results
Great Bear continues to intersect significant widths of high-grade gold mineralization. New shallow high-grade drill results between bedrock surface and approximately 150 vertical metres’ depth include:
- 16.56 g/t gold over 11.00 metres from 162.50 to 173.50 metres in drill hole BR-196 on drill section 21100.
- This included a high-grade core of 32.90 g/t gold over 3.10 metres from 162.50 to 165.60 metres.
- 20.24 g/t gold over 7.35 metres from 163.50 to 170.85 metres in drill hole BR-201 on drill section 19950 (1,150 metres southeast of the previous section within the same zone).
- This included a high-grade core of 211.00 g/t gold over 0.50 metres from 165.00 to 165.50 metres.

High-Density Drill Panel 100 m x 450 m
Great Bear is completing systematic high-density drilling along the LP Fault, including ongoing step-downs which continue to expand the mineralized zone at depth. Fifteen closely spaced drill holes on sections located 25 – 50 metres apart were completed along 100 metres of strike length on drill sections 20100 to 20200 at depths from bedrock surface to approximately 450 vertical metres.
High-grade and bulk-tonnage style gold intercepts were intersected at all sections and depths and demonstrate excellent continuity of the mineralized zone on these tight drill spacings. Results include:
- 1.34 g/t gold over 29.45 metres from bedrock surface (18.00 to 47.45 metres) in drill hole BR-209 on drill section 20100.
- 1.31 g/t gold over 65.95 metres from 57.05 metres to 123.00 metres in drill hole BR-202 on drill section 20125 (25 metres from previous).

* 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. Interval widths are calculated using a 0.10 g/t gold cut-off grade with up to 3 m of internal dilution of zero grade.
New Cross Sections
With many areas of the LP Fault now drilled on 25 to 75 metre centres, a more detailed understanding of gold zone geometries is emerging. Ongoing drill results demonstrate:
- To date all drill holes on all drill sections completed into the LP Fault gold system within the approximately 4.2 kilometre long area of current higher density drilling have successfully intersected gold mineralization.
- Drill section 20150 in Figure 3 provides an example of higher-density drill spacing and mineralized zone continuity. Limited additional drilling is expected to be required on this section for mineralized zone modeling to approximately 400 metres depth.
Figure 3: Cross section 20150 showing higher density drill spacing. A 400 metre scale bar has been added for reference.
- Cross section 19925 (located 225 metres to the southeast of section 20150) demonstrates how at some locations along the LP Fault, the main mineralized zone bifurcates into several parallel gold zones which typically extend to bedrock surface.
Figure 4: Cross section 19925 showing up to five parallel gold zones. This drill section is located 225 metres to the southeast of section 20150 in the same gold zone). A 400 metre scale bar has been added for reference.
- Conversely, cross section 21100 (located 1,175 metres northwest of section 19925 in the same zone), demonstrates how the gold mineralized system consolidates into a single mineralized zone in areas of the LP Fault.
- Section 21100 also demonstrates how some sections of the LP Fault have yet to be drilled at higher densities. Similar gold zone characteristics are observed on these loosely drilled sections as at more densely drilled sections.
As shown in the Company’s VRIFY model posted to Great Bear’s web site at www.greatbearresources.ca, halos of low grade gold mineralization (0.10 g/t to 1.00 g/t gold) typically also occur adjacent to, and between, the highlight intervals published in news releases. All of the gold zones at the Dixie Project remain open to expansion.

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 principal styles of gold mineralization:
- High-grade gold in quartz veins and silica-sulphide replacement zones (Dixie Limb, Hinge and Arrow zones). Hosted by mafic volcanic rocks and localized near regional-scale D2 fold axes. These mineralization styles are also typical of the significant mined deposits of the Red Lake district.
- High-grade disseminated gold with broad moderate to lower grade envelopes (LP Fault). The LP Fault is a significant gold-hosting structure which has been seismically imaged to extend to 14 kilometres depth (Zeng and Calvert, 2006), and has been interpreted by Great Bear to have up to 18 kilometres of strike length on the Dixie property. High-grade gold mineralization is controlled by structural and geological contacts, and moderate to lower-grade disseminated gold surrounds and flanks the high-grade intervals. The dominant gold-hosting stratigraphy consists of felsic sediments and volcanic units.
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 330 km2 of highly prospective tenure across 5 projects: the flagship Dixie Project (100% owned), the Pakwash Property (earning a 100% interest), the Dedee Property (earning a 100% interest), the Sobel Property (earning a 100% interest), and the Red Lake North 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.
