GREAT BEAR DRILLS 125.00 M OF 1.08 G/T GOLD BETWEEN BEAR-RIMINI AND YUMA ZONES, AND 15.02 G/T GOLD OVER 2.50 M, WITHIN 26.00 M OF 2.55 G/T GOLD BETWEEN YUMA AND AURO ZONES; PROSPECTIVE GEOLOGY MAPPED ALONG 15 KILOMETRES; SGH SURVEY FINDS NEW TARGETS
Great Bear Resources Ltd. has released results from its continuing 90,000-metre drill program at its 100-per-cent-owned Dixie project in the Red Lake district of Ontario. Highlights of recent progress include:
-
On-strike extensions of key geological units that host gold mineralization were drilled by Great Bear to date have now been mapped, drilled and identified in historical drilling along 15 kilometres of the 18.5-kilometre-long LP fault.
- The company continues to advance its three-dimensional modelling of the LP fault mineralization as additional drill information is received. An up-to-date image of the currently drilled interpreted mineralized zone is provided in an image on the company's website.
- Results of a spaciotemporal geochemical hydrocarbon (SGH) survey completed in summer 2019 along four kilometres of the LP fault have also now been received, and four new drill targets have been identified, as shown in an image the company's website.
Chris Taylor, president and chief executive officer of Great Bear, said: "In a district where gold is usually mined from discontinuous veins averaging a few metres in width, often at kilometre-scale depths, the near-surface, multikilometre extent of our LP fault discovery instead resembles other Archean-age gold deposits across Ontario and Quebec. We continue to intersect high-grade gold intervals with comparable widths and grades to what have been mined at the major high-grade deposits in Red Lake; however, these occur within wide envelopes of moderate- to low-grade gold mineralization, which we observe projecting to surface. During September and October, mapping crews discovered outcrop exposures of our felsic target geology, similar to what we're drilling from Bear-Rimini to Auro, along approximately 15 kilometres of strike length. We have also now drilled the same units one kilometre to the southeast of the Auro zone, with assays pending, and through examination of historical drill core we see that Noranda in 1993 drilled similar rocks eight kilometres to the southeast of the Auro zone."
Highlights of recent LP fault
drill results include:
-
Drill hole BR-043, located between the Bear-Rimini and Yuma subzones, intersected multiple gold intervals along 253.90 metres of core length including 125.00 metres of 1.08 g/t gold. Complete assays from the reported interval, showing continuity of gold mineralization are provided in the associated table.
-
Drill hole BR-035, located between the Auro and Yuma subzones, intersected multiple gold intervals over 111.30 metres of core length, including 15.02 g/t gold over 2.50 metres, within a broader interval of 26.00 metres of 2.55 g/t gold. Separate additional gold intervals include 9.20 g/t gold over 5.30 metres, within a broader interval of 56.10 metres of 1.26 g/t gold, as shown in an image on the company's website.
- The gold-mineralized system tends to increase in apparent width with increasing depth in most locations.
Great Bear is fully financed with approximately $17-million in cash and $27-million on a fully diluted basis. The company plans to continue drilling along strike of the LP fault in generally 100-metre-to-one-kilometre stepouts, with additional drilling at Dixie Limb and Hinge zones through the remainder of 2019 and throughout 2020.

Drill results are spaced along 1.6 kilometres of strike length
as shown with included section numbers.
* Widths are drill-indicated core length, as insufficient
drilling has been undertaken to determine true widths at this
time. Average grades are calculated with uncapped 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 less than
three m of internal dilution of zero grade.
The LP fault represents a major break/deformation zone between felsic and mafic volcanic rocks and is associated with significant gold-bearing alteration. It is similar in character to other large gold-hosting deformation zones in Archean greenstone belts. Well-known Canadian examples include the Larder Lake Cadillac Break that extends through Kirkland Lake and Val d'Or, the Porcupine Destor fault zone of the Timmins camp, the Detour Lake fault zone, the Pike fault in the Meliadine camp of Nunavut, and the Cochenour-Gullrock deformation zone of the Red Lake mine complex.
Highlights of previously reported drill results from the LP fault include 2.00 metres of 194.21 g/t gold and 14.00 metres of 12.33 g/t gold in the Bear-Rimini area, 1.50 metres of 101.71 g/t gold within a broader interval of 42.00 metres of 5.28 g/t gold in the Auro area and 2.00 metres of 27.77 g/t gold within a broader interval of 7.00 metres of 11.08 g/t gold in the Yuma area.
SGH sampling results
A 2,100-sample SGH survey was conducted during summer 2019 along the LP fault and North fault in the Bear-Rimini to Auro area, as originally disclosed on Aug. 1, 2019. An earlier, smaller test survey at the Hinge and Dixie Limb zones had successfully identified the surface projection of portions of both of those zones.
New results from the LP fault SGH survey identified four new target areas that require follow-up drilling, as shown in an image on the company's website.
Target D centres on the North fault and has not yet been drilled.
Target B is located within the felsic volcanic rock package between the LP fault and North fault, and is not proximal to the LP fault zone. This target constitutes an entirely new drill target that may be associated with a linear geophysical trend that may represent a new structure that parallels the LP fault.
Target C was already a drill target in the Yuma area and drilling is continuing in this area.
Target A was previously drilled with one hole (BR-015) returning no significant values. One additional regional drill hole is pending from within this target area.
As was also the case at the Hinge and Dixie Limb zones, many areas of the LP fault where Great Bear has successfully intersected gold mineralization in underlying bedrock, including the discovery drill holes at Bear-Rimini, Yuma and Auro, were not detected by the SGH survey. As such, areas without SGH targets cannot be excluded from planned drilling; however, the SGH targets can be utilized to help prioritize drill order, and have the potential to lead to new discoveries in areas that might not otherwise be drilled.
Continuing regional exploration
The company also completed a series of seven drill holes testing other drill targets. Drill holes BR-011a, 13, 14, 15, 16 and 17 tested areas north of the LP fault. Structural deformation related to the LP fault is mostly absent in these drill holes, along with the associated widespread silica-albite-sulphide mineralization observed in conjunction with gold mineralization elsewhere.
This drilling suggests that the development of significant gold mineralization within the felsic sedimentary and volcanic units requires structural preparation related to the major faults. The North fault, which is interpreted to parallel to the LP fault for over 18 kilometres of strike length, and also presents a target on the SGH survey, remains an exploration target that will require direct drill testing.
Drill hole BR-010, located 250 metres to the northwest of the Bear-Rimini zone along the LP fault on Section 22700 intersected various minor intervals of gold mineralization along 259.50 metres of core length, including 10.47 g/t gold over 0.50 metre, 1.18 g/t gold over 6.00 metres, and 0.23 g/t gold over 17.00 metres. Key felsic volcanic marker units observed at Bear-Rimini, Yuma and Auro were absent in this area, and gold mineralization is less well developed than where these marker units are present farther to the southeast.
Of note, the missing marker units were subsequently identified by Great Bear's mapping crews in outcrop approximately 750 metres to the northwest of BR-010, farther along strike of the LP fault, as shown in an image on the company's website. The company will follow up with drilling in this area during the winter program.
High-resolution airborne geophysics completed by Great Bear in 2017 also suggests parallel structures to the LP fault and North fault may be present between the two structures. These will also be drill tested during the winter drill program.
Great Bear will continue to provide regular drill program updates throughout the remainder of 2019 and through 2020. Assay results will continue to be released in batches as received and processed. Approximately 26,000 metres of drilling remain to be completed as part of the company's continuing 90,000-metre drill program.
The company also reports it has granted an aggregate of 35,000 stock options to consultants of the company, exercisable at $7.68 per share for a period of five years. The options are subject to a four-month hold period.
About Great Bear Resources Ltd.
Great Bear is a well-financed company based in Vancouver, Canada, managed by a team with a record of success in the mineral exploration sector. Great Bear holds a 100-per-cent interest, royalty free, in its flagship Dixie property, which is road accessible year-round by Highway 105, a 15-minute drive from downtown Red Lake, Ont. The Red Lake mining district is one of the premier mining districts in Canada, benefiting from major active mining operations, including the Red Lake gold mine of Newmont Goldcorp Corp., plus modern infrastructure and a skilled work force.
Drill core is logged and sampled in a secure core storage facility located in Red Lake, Ont. Core samples from the program are cut in half, using a diamond cutting saw and are sent to SGS Canada Inc. in Red Lake, Ont., and Activation Laboratories in Ontario, both of which are accredited mineral analysis laboratories, for analysis. All samples are analyzed for gold using standard fire assay-atomic absorption techniques. Samples returning over 10 g/t gold are analyzed utilizing standard fire assay-gravimetric methods. Pulps from approximately 5 per cent 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 one-kilogram 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. No QA/QC issues were noted with the results reported herein.
