Great Bear Doubles Vertical Extent of LP Fault, Intersects High-Grade Gold at 942.20 m Downhole: 15.57 g/t Gold Over 3.05 m
Press Release
March 29, 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.
Expansion of the LP Fault
- Deep drilling has doubled the drill-confirmed vertical extent of the LP Fault gold zone, which begins at bedrock surface, to approximately 800 vertical metres. The area of ongoing grid drilling extends along 4 kilometres of strike length. Figure 1 and Figure 2.
- Three new 400 – 450 metre step-down holes drilled along 500 metres of strike length all successfully intersected the continuation of the LP Fault host rocks and gold mineralization at depths of 700 – 820 vertical metres.
- Gold grades and mineralized zone thickness were better at depth on two of three tested drill sections.
- Initial deep drilling tested below the most weakly mineralized segment of the LP Fault, formerly referred to as the “Gap” zone (February 13, 2020).
- Large scale step-out drilling at depth, including below areas of high-grade gold mineralization, will continue throughout 2021.
High-Grade Gold in the First Deep LP Fault Drill Holes
- High-grade gold was intersected at depth in two of the three deep drill holes, with better grades and thickness than previously observed in the near surface. All three deep drill holes contained multiple intervals of gold mineralization. Table 1 and Table 2.
- BR-260 is the deepest LP Fault drill hole to date. It assayed 15.57 g/t gold over 3.05 metres from 942.20 to 945.25 metres, within a broader interval of 1.08 g/t gold over 70.25 metres from 906.15 to 976.40 metres. Figure 3 and Figure 4.
- While high-grade intervals are the primary drill targets at these depths, the dual high-grade and bulk-tonnage character of the LP Fault gold zone remains strongly developed at depth.
- Oriented core data collected from these initial deep holes will assist with determining controls to higher grade panels within the broad envelope of gold mineralization.
Great Bear has now published results from 270 LP Fault drill holes and anticipates at least 130 additional LP Fault drill holes will be completed by the end of 2021, for a total of at least 400 drill holes.
Chris Taylor, President and CEO of Great Bear said, “We drilled below the most weakly mineralized segment of the LP Fault with our first deep holes, and discovered better gold mineralization at depth. After 270 drill holes we have yet to find the limits of the LP Fault’s gold mineralization. Mesothermal gold systems of this type, particularly in the Red Lake area, can extend vertically over kilometres. We are currently working with in-house and external modelers to finalize 2021 drill plans, and will provide guidance over the coming weeks on expected timing of delivery of initial estimates of mineral resources.”

* 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.

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.
