Great Bear Expands LP Fault Gold System at Depth: 10.06 g/t
VANCOUVER, BC, July 6, 2020 /PRNewswire/ - Great Bear Resources Ltd. (the "Company" or "Great Bear"), (TSX-V: GBR) (OTCQX: GTBAF) today reported results from its ongoing fully funded $21 million exploration program at its 100% owned flagship Dixie Project in the Red Lake district of Ontario.
Chris Taylor, President and CEO of Great Bear said, "The most recent drilling along 650 metres of strike length of the multi-kilometre LP Fault gold system has shown mineralization typically expands at depth. As the system broadens, we generally observe an increasing number of high-grade gold intervals within broader halos of moderate gold grades. Gold mineralization continues to show excellent continuity within and between drill sections in all locations tested to date. A new gold zone adjacent to the LP Fault zone was also discovered at approximately 750 metres vertical depth, consistent with our model of a greater than one kilometre wide structural zone at Dixie that has the potential to host additional new gold discoveries."
The Company has completed 120 of approximately 300 planned drill holes into the LP Fault target, as part of its 5 kilometre long by 500 metre deep grid drill program. Current drill hole locations and results are provided in Figure 1, and in Table 1, respectively.
Deeper Drilling on Section 20000:
New drill hole BR-129 is the deepest drill hole on section 20000. It intersected multiple mineralized intervals along 173.10 metres of core length, highlights of which include:
- 559.00 g/t gold over 0.50 metres, within a broader interval of 10.06 g/t gold over 31.25 metres. The total mineralized interval is 4.07 g/t gold over 80.50 metres. Figure 2.
- The 10+ g/t gold interval over more than 30 metres is the widest high-grade gold interval drilled at the LP Fault to date. Results suggest the mineralized zone is expanding at depth.
- BR-129 extends known mineralization on this section from bedrock surface to approximately 400 metres vertical depth. This is one of the deepest drill holes intersecting the LP Fault to date.
Continuity of gold mineralization is demonstrated by shallower drilling on the same section as BR-129:
- New drill hole BR-139 intersected the same mineralized zone 100 metres vertically above BR-129. Assays include 32.41 g/t gold over 3.75 metres, within a broader interval of 13.18 g/t gold over 9.75 metres.
- Previously reported drill hole BR-137 (June 8, 2020) intersected the same zone 100 metres vertically above BR-139, assaying 31.33 g/t gold over 20.55 metres.
- All four of the drill holes on section 20000 contain mineralized intervals of approximately 100 g/t gold over at least 0.50 metres, with two of the drill holes having intervals of greater than 500 g/t gold over at least 0.50 metres width. The mineralized zone projects to the bedrock surface and remains open at depth.
Increased Zone Thickness on Section 20600:
A significant increase in apparent thickness of the LP Fault gold mineralized zone was drilled 600 metres to the northwest of BR-129 on drill section 20600:
- New drill hole BR-142 was completed in a 240 vertical metre gap in drill section 20600. Figure 3.
- BR-142 intersected multiple gold intervals along 454.45 metres of core length.
- Together with previously reported drill hole BR-067 (February 13, 2020; also see Figure 3), drilling suggests a significant apparent thickening of the LP Fault gold system on this section at increasing depth.
- Highlight intervals include:
- 32.39 g/t gold over 4.25 metres, which included 112.00 g/t gold over 0.50 metres, and
- 26.49 g/t gold over 8.85 metres, which included 197.00 g/t gold over 1.00 metre.
- Both intervals above occur within a broader interval of 7.26 g/t gold over 53.50 metres.
- Additional gold intervals include 1.41 g/t gold over 26.00 metres, which includes 4.22 g/t gold over 4.50 metres, and 1.54 g/t gold over 37.50 metres, which includes 4.85 g/t gold over 4.55 metres
- Previously reported drill hole BR-037 is located on the same section 100 metres vertically above BR-142. It contained multiple gold intervals along 366.95 metres of core length, including 16.60 g/t gold over 6.0 metres, 35.96 g/t gold over 1.73 metres within a broader interval of 2.01 g/t gold over 66.06 metres, and 59.05 g/t gold over 1.60 metres within a broader interval of 5.60 g/t gold over 25.25 metres (October 30, 2019).
- All four drill holes on section 20600 intersected similar gold mineralization. Results suggest strong apparent continuity of gold mineralization along approximately 500 vertical metres which remains open at depth.
New Gold Zone on Section 20650:
The deepest drilling completed to date at the LP Fault has intersected increased apparent thicknesses of gold mineralization at greater depths, and discovered a new gold zone in the hanging wall of the LP Fault:
- New drill hole BR-140 intersected multiple gold intervals along 725.00 metres of core length. Figure 4.
- Highlights include 15.45 g/t gold over 3.50 metres, within a broader interval of 2.09 g/t gold over 66.00 metres, and 6.61 g/t gold over 4.50 metres, within a broader interval of 1.61 g/t gold over 36.00 metres.
- At 867.00 to 877.00 metres down hole, corresponding to a vertical depth of approximately 750 metres, drill hole BR-140 intersected a new gold zone within the mafic hanging wall rocks immediately adjacent to the LP Fault zone, assaying 7.20 g/t gold over 1.50 metres, within a broader interval of 1.15 g/t gold over 10.00 metres.
- Future drilling of the LP Fault will include similar drill holes that penetrate into the LP Fault hanging wall at depth, in order to test for extensions to this new zone, and potential additional parallel zones.
- New drill hole BR-141 intersected the LP Fault zone 100 metres vertically below BR-140 and returned multiple gold intervals along 482.90 metres of core length. Highlight intervals include (also refer to Table 1):
- 28.60 g/t gold over 2.00 metres, within a broader interval of 3.58 g/t gold over 22.00 metres; and
- 61.91 g/t gold over 1.00 metre, within a broader interval of 2.47 g/t gold over 77.70 metres; and
- 5.29 g/t gold over 7.50 metres.
- Drill section 20650 also includes previously reported drill hole BR-118 which returned 18.57 g/t gold over 13.00 metres, including 132.00 g/t gold over 0.50 metres, within a broader interval of 2.67 g/t over 104.15 metres (May 4, 2020).
- All three drill holes on section 20650 intersected similar gold mineralization. Results suggest strong apparent continuity of gold mineralization along approximately 400 vertical metres which remains open at depth.
Approximately 180 drill holes remain to be completed as part of the Company's ongoing fully funded 2020 LP Fault drill program. Additional drill holes are also planned into the Dixie Limb, Hinge and Arrow zones, in addition to other regional targets. The Company remains fully funded for this work.

*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. Average widths are calculated using a 0.10 g/t gold cut-off grade with up to 3 m of internal dilution of zero grade.
Figure 2: Cross section 20000. BR-129 contains the widest high-grade gold interval drilled along the LP Fault to date. All drill holes on this section contain intercepts of greater than 100 g/t gold, and apparent continuity of mineralization for approximately 400 vertical metres.

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 principle 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

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.
