Great Bear Reports 97% Gold Recoveries from Preliminary Hinge Zone Metallurgical Tests

TSX-V: GBR

VANCOUVER, BC, Nov. 12, 2020 /CNW/ - Great Bear Resources Ltd. (the "Company" or "Great Bear") (TSXV: GBR) (OTCQX: GTBAF) today reported the first gold recovery test results from its 100% owned flagship Dixie Project, in the Red Lake district of Ontario.

Chris Taylor, President and CEO of Great Bear said, "The first results from a preliminary suite of metallurgical tests planned for the various mineralized zones at Dixie have returned very high gold recoveries. Hinge zone high-grade gold samples averaging approximately 13 g/t gold recovered between 95% - 97 % of the head grade gold from conventional cyanidation bottle roll leach tests. Results in this range had been expected, as free gold dominates the Hinge zone and all other zones at Dixie, and high gold recoveries are typical of such systems. We will periodically release gold recovery results from representative samples originating from all of our gold zones over the coming months."

Details of Hinge Zone Gold Recovery Results

• A composite sample of 18.0 kilograms representing 10.9 metres (core length) of drill core was selected for processing from the Hinge zone.
  
  
• Two approximately one-kilogram representative samples of Hinge zone gold mineralization collectively averaging 13.07 g/t gold head grade were analyzed at Blue Coast Research Ltd. of Parksville, British Columbia.
  
  
• Samples were processed through a standard 48-hour bottle roll procedure at 40% solids, using a 1.0 g/L sodium cyanide solution.
  
  
• Two primary grind samples: 1) 80% passing ("p80") 112 µm, and 2) p80 74 µm returned 95.4% and 97.2% gold recoveries, respectively. Table 1 and Figure 1.
  
  
• The high reported gold recoveries are similar to those reported from other mines in the Red Lake area.
  
  
• Additional metallurgical test work consisting of sodium cyanide bottle roll tests on samples from the Hinge, Limb and LP Fault zones on the Dixie Project are currently underway. The Company will also begin gravity circuit recovery tests in 2021.

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 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.
