November 24, 2021 – Vancouver, British Columbia, Canada – Great Bear Resources Ltd. (the "Company" or "Great Bear", TSX-V: GBR; OTCQX: GTBAF) today reported drill results from its 100% owned flagship Dixie Project, in the Red Lake district of Ontario.
Chris Taylor, President and CEO of Great Bear said, “We recently resumed drilling near the Hinge and Limb zones and discovered a new, high-grade gold zone west of those targets. The new “Midwest” zone
closely resembles the style of gold mineralization observed at the Dixie Limb zone; both occur at the sheetlike contacts between different basalt units and consist of silica-sulphide replacement style mineralization
including high-grade gold. Several historical holes which tested the Limb zone, did not penetrate far enough to the west to intersect the Midwest zone. In addition to drilling other new, untested basalt
contacts, the Company will re-enter and extend previously drilled holes into the Midwest area.
Additionally, ongoing drilling of the LP Fault zone continues to return significant gold intervals at depths
ranging from bedrock surface to over 600 vertical metres.”
New Midwest Zone Drilling Highlights
• Drill hole DL-071 intersected the new “Midwest” zone, located 275 metres northwest of the Hinge
zone and 250 metres south of the Dixie Limb zone, assaying 20.27 g/t gold over 1.75 metresfrom
812.35 to 814.10 metres downhole. The total mineralized interval was 5.69 g/t gold over 7.05
metres from 809.95 to 817.00 metres downhole. Table 1.
• The new discovery consists of high-grade gold in silica-sulphide replacement alteration at the
subvertical planar contact between two basalt flows and is most similar to the Dixie Limb zone in
style.
• Until this discovery, it was thought that the only mineralized basalt-basalt contact occurred at the
Dixie Limb zone. It is now confirmed that additional basalt-basalt contacts can also localize
silica-sulphide replacement mineralization including high-grade gold.
• Great Bear’s drilling and geophysical data suggest additional basalt-basalt contacts may occur
within the mafic volcanic package southwest of the LP Fault zone, defining new drill targets.
All significant gold zones at Dixie occupy a 1.4 kilometre wide “dilation zone” shown on Figure 1, where
many geological contacts and structures are mineralized. A report on seismic surveys by Zeng and Calvert,
2006 presents an interpretation that this structural zone reaches the base of the continental crust. At the
Dixie project, the zone contains a broad structural corridor with more than 18 kilometres of strike length.
Gold has been drilled along 11 kilometres of strike length to date. In addition to ongoing drilling of the LP
Fault, Phase 2 drilling will continue to test various new targets such as the new Midwest zone within
this broad structurally dilated and mineralized corridor.
New LP Fault Drilling Highlights
Ongoing LP Fault drilling continues to systematically expand gold mineralization, including at depth.
Current drill holes targeted the zone at various points along 2.9 kilometres of strike length, between
bedrock surface and approximately 600 metres vertical depth. Table 2.
New drilling primarily targeted 1) extensions to the 23 high-grade domains currently being modeled,
including at depth, and 2) the lower-grade halo up to 200 metres from the centre of the zone. Gold
mineralization is typically strongest within, and proximal to, the high-grade domains that occur towards
the centre of the zone. Highlights include:
• Drill holes BR-406 and BR-407 increase the drilled depth of the LP Fault gold zone to approximately
450 metres vertically from surface on their drill section. Results include:
o BR-406: 66.30 g/t gold over 0.50 metresfrom 407.30 metres to 407.80 metres downhole.
This occurred within a broader interval assaying 6.15 g/t gold over 7.20 metres from
406.80 to 414.00 metres downhole.
o BR-406: 42.60 g/t gold over 0.50 metres from 452.15 to 452.65 metres downhole. This
also occurred within a broader interval assaying 3.24 g/t gold over 12.25 metres.
o BR-406: The total mineralized interval was 2.03 g/t gold over 45.85 metres from 406.80
to 452.65 metres downhole.
o BR-407: 11.29 g/t gold over 3.00 metres from 496.00 to 499.00 metres downhole, which
occurred within a broad interval of 4.55 g/t gold over 25.50 metres from 473.50 to 499.00
metres downhole.
o BR-407: The total mineralized interval was 1.83 g/t gold over 91.35 metres from 430.40
to 521.75 metres downhole.
• Shallower LP Fault drill holes were also completed to fill in gaps of up to 100 metresin past drilling.
Drill hole BR-426 intersected several high-grade, mid-grade and low-grade gold intervals over
150.20 metres of core length, consistent with previously reported continuity of gold
mineralization in this area (see news releases of June 3, 2021 and September 9, 2021). Results
include:
o BR-426 collared in a broad low-grade gold interval from bedrock surface assaying 0.59 g/t
gold over 65.70 metres from 28.50 to 94.20 metres downhole.
o It also intersected high-grade gold assaying 16.07 g/t gold over 3.70 metres from 174.30
to 178.00 metres downhole. The broader mineralized interval was 3.10 g/t gold over
28.30 metres from 165.20 to 193.50 metres downhole.
• Shallow drill hole BR-438 intersected several mineralized intervals over 258.10 metres of core
length, including:
o 32.40 g/t gold over 0.50 metres from 72.10 to 72.60 metres downhole, within a broader
interval assaying 1.62 g/t gold over 11.20 metres from 66.70 to 77.09 metres downhole,
o 24.84 g/t gold over 0.90 metres from 128.35 to 129.25 metres downhole, within a
broader interval assaying 6.00 g/t gold over 3.90 metres from 128.35 to 129.25 metres
downhole,
o 37.50 g/t gold over 1.00 metre from 153.60 to 154.50 metres downhole, within a broader
interval assaying 2.53 g/t gold over 16.70 metres from 147.60 to 164.30 metres
downhole, and
o 40.00 g/t gold over 1.50 metres from 323.30 to 324.80 metres downhole.
• Shallow drill hole BR-463 intersected near-surface high-grade gold assaying 21.00 g/t gold over
1.10 metres from 49.60 to 50.70 metres downhole. The broader mineralized interval was 8.38
g/t gold over 4.20 metres from 46.50 to 50.70 metres downhole.
• Upcoming LP Fault drill results include direct targeting of high-grade domains such as BR7 at depth
(see news release of May 19, 2021). Assay results are pending.
Grid Drilling the Hinge, Limb and Midwest Area
Results from the Hinge and Dixie Limb zones were last reported on May 11, 2020 (Dixie Limb zone: 10.19
g/t gold over 19.00 metres from 1,008.55 metres downhole), and December 9, 2020 (Hinge zone: 15.18
g/t gold over 4.90 metres from 1,190.00 metres downhole). The Company has focused more than 90%
of its drilling on the adjacent LP Fault zone throughout 2020 and 2021.
Great Bear has begun a new grid-based drill program on 25 – 100 metre centres in the Hinge, Limb and
Midwest zone area which will support detailed mineral resource estimation drilling of these zones later in
2022. Grid drilling is initially expected to cover an area of approximately 400 metres of strike length by
600 metres of vertical extent, as shown in Figure 2.
The purpose of grid drilling is to collect gold mineralization results, together with geological and oriented
structural data that will be used to target steeply-plunging high-grade gold zones with shoot-like
geometries that comprise the primary targets within each of these zones, throughout 2022.
The new Midwest zone was discovered in a previously undrilled area in a 200 to 300 metre step-out
hole near the western margin of the newly planned drill grid. Figure 2 and Figure 3.
The Hinge zone was discovered by Great Bear in 2018 (see news release of August 22, 2018) and consists
of multiple sub-parallel “Red Lake style” high-grade gold-bearing, anastomosing quartz veins hosted by
mafic rocks. High-grade gold frequently concentrates in steeply-plunging shoot-like mineralized zones,
as is typical in the Red Lake district.
The adjacent Dixie Limb zone was discovered by Teck Resources Ltd. in the 1980’s and was the first gold
zone explored by Great Bear (see news release of September 7, 2017). The Limb zone consists of silicasulphide replacement mineralization containing mid- to high-grade gold located at the subvertical contact
between two basalt units.
Table 1: Dixie Limb, Hinge and Midwest zone drill results from expanded drill grid. Multiple gold-bearing
veins and mineralized contacts occur in this area. Grid drilling will define areas to focus upcoming
detailed definition of the high-grade “shoot-like” mineralized zones that are the primary targets in this
area.
