August 25, 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.

Key Results

Drill holes reported in this release primarily targeted the previously underexplored northwestern and southeastern areas of the 4.2 kilometre Phase 1 drill grid. Results expand and characterize the zone outboard from the Central LP Fault, which had seen the highest density Phase 1 drilling prior to this release. Figure 1.
High-grade gold controls have been identified along the LP Fault. Drilling has confirmed these controls in several areas, which will facilitate targeting of high-grade gold during Phase 2 drilling below the current 450 metre drill depth, and elsewhere along strike.
Steeply-plunging high-grade gold mineralization has been successfully targeted in the northwestern “Discovery” and southeastern “Viggo” areas of the LP Fault.
The number of high-grade gold domains being modeled at the LP Fault has been expanded from 17 to 23. This includes seven high-grade gold domains which are being modeled in the northwestern “Discovery” area.
Bulk tonnage style gold mineralization has been confirmed as continuous along more than 3 kilometres of strike length of the LP Fault and remains open to extension. New results from the previously under-drilled northwestern “Discovery” and “Gap” areas illustrate this continuity.
Chris Taylor, President and CEO of Great Bear said, “The confirmation of predictable high-grade gold controls within the LP Fault has clear, positive implications for our ability to target and model higher-grade mineralization, especially at depth. However, the confirmation of continuous mineralization at shallow depths in the “Gap” area is arguably the more significant development as we progress towards maiden mineral resource estimate publication by early next year. While clearly not the most strongly mineralized segment of the LP Fault, the “Gap” area contains mineralized intervals with similar grades and widths to those that have been incorporated into mine plans within other Canadian bulk tonnage gold deposits. These new results confirm the strongly mineralized Central and Discovery areas are connected as a continuously mineralized gold zone with clear bulk tonnage potential over three kilometres of strike length.”

With the 73 new drill holes contained in this release, Great Bear has reported 404 of the 440 LP Fault drill holes completed during Phase 1 drilling which will support maiden mineral resource estimation.

High-Grade Gold Controls

Recent drilling has included a focus on modeling higher-grade gold mineralization controls within the broad, bulk tonnage style gold system. Plunge controls to mineralization were interpreted using over 65,000 oriented core measurements, targeting the intersections of foliation fabrics and stratigraphy. These intersections frequently host increased widths and grades of gold mineralization.

In this release, Great Bear successfully targeted higher grade zones within the LP Fault in both the “Discovery” and “Viggo” areas, and will apply the same criteria beneath currently drilled areas and along 11 kilometres of strike length of the LP Fault (see news release of February 20, 2020) through 2022.

Examples of confirmed and interpreted plunge controls are included in Figure 1. These and additional interpreted plunge controls will be tested during Phase 2 drilling.

“Discovery” Area Results

Twenty six drill holes were completed in the original LP Fault “Discovery” area, located along the most northwesterly 700 metres of the 4.2 kilometre long Phase 1 drill grid. This area was the site of LP Fault discovery hole DNW-011 (May 28, 2019; 12.33 g/t gold over 14.00 metres). Highlights include:

Drill hole BR-365 extended gold mineralization approximately 100 metres deeper than past drilling on its section, assaying 15.04 g/t gold over 4.00 metres from 545.00 to 549.00 metres downhole, within a broader envelope of 3.13 g/t gold over 29.50 metres from 523.50 to 553.00 metres downhole. Figure 2.
Drill hole BR-394 assayed 150.00 g/t gold over 0.80 metres from 331.60 to 332.40 metres downhole, within a broader interval of 28.18 g/t gold over 4.80 metres from 331.60 to 336.40 metres downhole. The total mineralized interval was 3.83 g/t gold over 43.10 metres from 311.50 to 354.60 metres downhole. Figure 3.
Newly defined steeply northwest plunging high-grade gold controls were successfully confirmed in both BR-365 and BR-394, and will be targeted at depth below this area during Phase 2 drilling.
Most of the drill holes in the “Discovery” area contained multiple mineralized intervals. An example is drill hole BR-393 which contained four mineralized zones assaying 70.90 g/t gold over 1.00 metre from 110.75 to 111.75 metres, 1.26 g/t gold over 23.00 metres from 209.50 to 232.50 metres downhole, 0.60 g/t gold over 98.35 metres from 237.60 to 335.95 metres downhole, and 16.00 g/t gold over 1.15 metres from 355.25 to 356.40 metres downhole.
Drill hole BR-360 assayed 22.80 g/t gold over 1.20 metres from bedrock surface, within a broader interval of 1.66 g/t gold over 34.90 metres from 13.20 to 48.10 metres downhole. A separate interval of 0.88 g/t gold over 14.00 metres was also present from 153.00 to 167.00 metres downhole.
Drill hole BR-333 assayed 26.60 g/t gold over 0.80 metres from 130.30 to 131.10 metres downhole, within a broader interval of 0.71 g/t gold over 84.25 metres from 51.00 to 135.25 metres downhole.
Great Bear is currently modeling 7 high-grade gold domains within the broader bulk tonnage gold domains in the “Discovery” area of the LP Fault zone. Results are provided in Table 1, and expand both high-grade and bulk-tonnage style gold mineralization in this area.
