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.
