May 19, 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 fully funded $45 million 2021 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, “We are now entering the final months of near- surface maiden mineral resource estimation drilling of the central LP Fault zone, and are modeling 17 distinct high-grade gold domains within the broader LP Fault gold mineralized system. For the first time, we provide a detailed long section of the upper portion of one of these high-grade domains, a summary of all drill results within that long section, and detailed maps of the high-grade domains within the broader LP Fault gold system.”

Great Bear plans to release detailed high-grade and bulk tonnage domain information over the coming months. This news release includes the first of this information.

* 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.

Figures 1, 2, 3, 4 and 5 respectively show: 1) A detailed long section of high-grade domain “BR7”, which is one of 17 high-grade domains currently being drilled, 2) a map of all high-grade domains within the LP Fault, 3) A more detailed map of the high-grade domains in the central LP Fault zone, including surrounding bulk tonnage style mineralization, and 4) two cross sections through high-grade domain BR7. Table 1 provides all gold intercepts from BR7 shown in Figure 1. Table 2 provides all new gold assay results from the most recent LP Fault drilling.

With the 17 drill holes included in this release, Great Bear has released 300 LP Fault drill holes to date.

Highlights of Current Results

• New drill holes reported in this release intersected the LP Fault zone from approximately 20 to 500 metres vertical depth along 2.2 kilometres of strike length.

• Drill holes were located a) above previous drilling, in order to extend gold mineralization towards surface, and b) within 75 to 100 metre previously undrilled gaps in the zone.

• Two drill holes are step-ups that extend gold mineralization by more than 75 metres above previous drilling to the near-surface:
• BR-298 assayed 22.79 g/t gold over 4.80 metres from 58.30 to 63.10 metres downhole, within a broader mineralized interval assaying 3.32 g/t gold over 43.80 metres from 29.70 to 73.50 metres downhole.
• BR-299 assayed 13.27 g/t gold over 2.35 metres from 34.90 to 37.25 metres downhole, and 4.12 g/t gold over 10.35 metres from 53.90 to 64.25 metres downhole. The total mineralized interval was 2.30 g/t gold over 39.30 metres from 32.20 metres to 71.50 metres downhole.

• New bulk-tonnage type intercepts include:
• 3.07 g/t gold over 35.60 metres from 117.00 to 152.60 metres downhole in drill hole BR-320.
• 1.11 g/t gold over 91.60 metres from 349.50 to 441.10 metres downhole in drill hole BR-285.
• 1.00 g/t gold over 91.40 metres from 473.60 to 565.00 metres downhole in drill hole BR-286.

• Drill holes with multiple intervals of gold mineralization including both high-grade and bulk tonnage type results include:
• BR-276 which assayed 25.57 g/t gold over 2.50 metres from 233.50 to 236.00 metres downhole, and 4.10 g/t gold over 23.85 metres from 462.25 to 486.10 metres downhole, including a high-grade core of 68.40 g/t gold over 0.95 metres from 485.15 to 486.10 metres downhole.

Results continue to demonstrate excellent continuity of high-grade and bulk-tonnage gold mineralization. The LP Fault zone remains open to extension in all directions.

About High-Grade Gold Domains and BR7

The 17 high-grade domains are structurally and geologically distinctive from the surrounding lower grade, bulk tonnage style gold mineralization. Together, they span a strike length of 4.2 kilometres and occur within eight larger stratigraphically controlled lower grade domains. They are characterized by high degrees of strain and/or transposed quartz vein zones following two distinct structural fabrics and transition from upper greenschist to lower amphibolite facies metamorphism. Gold in the high-grade domains is generally observed as free gold, is often transposed into, and overgrows the dominant structural fabrics, and is higher-grade on average than the surrounding bulk tonnage gold zones.

Domain BR7, presented in this news release, has a surface strike length of 620 metres and has been drilled to a depth of 500 metres (where it remains open to extension). BR7 is a high strain zone hosted within strongly altered (albite, biotite, +/- quartz veined) felsic volcanic rocks and occurs oblique to the dominant geological contacts. It has an average strike orientation of 270 degrees and dips 74 degrees to the north.

Drilling is planned to intersect the various high-grade domains at 40 – 50 metre spacing. Figure 1 demonstrates how drilling is nearing completion within the upper portions of domain “BR7”, with few drill holes now required to provide the desired drill density for upcoming maiden resource estimation. Drilling is also nearing completion in the near-surface portions of all 17 high-grade domains along more than 4 kilometres of strike length of the central LP Fault. This drilling is expected to be completed from surface to an average of approximately 400 metres depth by year end.

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.
