Vancouver, British Columbia--(Newsfile Corp. - January 19, 2022) -
Blue Star Gold Corp. (TSXV:
BAU) (FSE: 5WP0) (OTCQB: BAUFF) ("Blue Star"
or the
"Company")
is pleased to provide results
from an additional eight (8) drill holes from the 2021 exploration program at its Ulu Project located in the
High Lake Greenstone Belt, Nunavut. Results from ten (10) drill holes remain outstanding.
Highlights from the recently completed drill program:
Central Zone fence: Central-C (21BSG010) returned
5.21 g/t gold over 3.00 metres
approximately 50 metres vertically below surface
Axis Zone returns continuous anomalous values from modelled structure adjacent to the
underground workings; 21BSG009 returns
2.51 g/t gold over 3.00 metres
Axis/Central zone returns gold values at a similar geochemically defined contact as the one that
hosts the Flood Zone Deposit; 21BSG015 returned 3.80 g/t gold over 0.79 metres
Potential important new targeting tool identified:
Geochemical sampling results have identified high, moderate, and low titanium basalts (high-
Ti, mod-Ti, low-Ti) at Ulu. The SW dipping Flood Zone deposit is hosted in a high angle
structure juxtaposing the high-Ti basalt unit with the mod-Ti basalt on the west limb of the Ulu
anticline. The NE dipping Central "C" Zone is found at the faulted contact between the high-Ti
and mod-Ti units on the east limb of the fold
The recognition that the host structures for gold mineralization occur at faulted contacts
between lithochemically distinct mafic flows provides a deeper understanding of structural
controls on mineralization and allows for more focused targeting for future drill programs
CEO, Grant Ewing, stated, "It is very encouraging that the technical team continues to find new and
innovative ways to more effectively assess the multitude of target areas over our extensive district scale
landholdings. High precision lithogeochemistry is unraveling the volcanic stratigraphy and linked with our
structural interpretation, we now have a much better understanding of the controls of the major
mineralized breaks. The current priority sequence is initially testing targets near our high-grade Flood
Zone gold deposit, and gradually stepping out to more regional priority target zones. We look forward to
receiving the balance of the results from our 2021 program as some of the strongest results are
anticipated in the drill holes that are still outstanding."
"Results for an additional ten drill holes are outstanding from the 2021 exploration program in the NFN,
Central and Gnu areas but are expected soon. With recent geochemical work refining the stratigraphy
hosting the better-known mineralized zones in conjunction with our results to date, the exploration team is
working on defining a balanced infill, expansion and new discovery program for 2022," commented
Darren Lindsay, Vice President Exploration.
Summary
Recent reviews of the geochemical data have indicated the presence of a 'high-Ti' and at least one 'low-
Ti' mafic volcanic sequence. The contact zones of the high-Ti sequence appear to be closely associated
with strong alteration and gold anomalism including defining the Flood Zone deposit structural corridor.
Further work is required to conclusively add this targeting tool to our exploration toolbox.
The results presented today are the initial drill evaluations of the Axis Zone, a target zone located in the
hanging-wall of the Flood Zone Deposit within 100 metres of the historical underground workings, and a
drill fence across three parallel zones known as Central A, B, and C located approximately 250 metres
east of the Flood Zone deposit.
The Axis Zone target was defined by historical surface sampling, alteration mapping and limited
historical shallow drilling. Blue Star drilling confirmed the mineralized trend with stronger results located
closer to the projected lateral intersection of the Axis Zone and Central Zone. This is also an area where
the geochemically defined stratigraphy indicates a similar structural juxtaposition as the one observed at
the Flood Zone.
A drill fence testing the Central Zones evaluated the three known mineralized planes from shallow 50
metre vertical levels to deeper 300 metre vertical levels below surface. Drill results show that gold
mineralization extends to the deepest level tested. Current understanding suggests that the three zones
may converge at depth, providing a compelling target area for future drill campaigns.
One additional drill hole from the original Gnu polymetallic vein is reported which did not intercept the
expected target most likely due to a change in structural trend of the interpreted vein feature. Additional
detailed drilling is required to follow up in this target area in 2022 (previously reported 21BSG006: 2.18
m of 11.06 g/t gold).
Discussion of results
Gnu Zone
21BSG-008:
Gnu Zone original polymetallic vein test. This drillhole tested the continuation of a modelled
high-grade polymetallic quartz vein at a vertical depth of 90 metres, collared south along strike from
BS2020-ULU-007 (52.7 g/t gold from 25.0 - 27.0 m), 92VD161 (18.8 g/t gold from 165.37 - 167.85 m),
and 21BSG-006 (11.06 g/t gold from 48.04 - 50.22 m). The drillhole intersected gabbro for the length of
the hole, with localized moderate to strong leucoxene alteration. Although some intervals of anomalous
arsenic were seen in assay data, no intervals of anomalous gold were reported. The polymetallic quartz
vein was not intersected, but lithological and assay data has helped inform a new working interpretation
of the location, azimuth and dip of the target which will be used for further drill evaluation.
Axis Zone
21BSG-009:
Axis Zone acicular trend. This drillhole tested two modelled basalt-hosted acicular
arsenopyrite trends situated between the Flood Zone and the Central acicular arsenopyrite trends. A
highly strained interval with quartz, 4% acicular arsenopyrite, 7% blebby chalcopyrite, 2% blocky
chalcopyrite and 4% blocky pyrite was intersected from 83.00 - 86.00 metres and returned gold assay
values of 2.51 g/t. These drill results helped inform a more robust reinterpretation of the Axis Zone
acicular arsenopyrite trend, which has been remodelled as one, rather than two, planes subparallel to
both the Flood Zone and the Central acicular arsenopyrite trends. This interpretation is supported by drill
results from 21BSG-016.
21BSG-016:
Axis Zone acicular trend
.
Similar to hole 21BSG-009, this drillhole tested two modelled
acicular arsenopyrite Axis trends. It is collared 60 metres northwest of 21BSG-009 and intersects
variably textured and altered basalt for the length of the hole. From 88.05 - 89.49 metres, 2.26 g/t gold
(including 4.30 g/t gold over 0.49 metres) was intersected in a basalt-hosted calc-silicate altered quartz
vein with 7% subhedral arsenopyrite, 2% pyrrhotite and 1% pyrite. These drill results support the re-
interpretation of the location, azimuth and dip of the Axis plane which was initiated by results from hole
21BSG-009.
21BSG-015:
Axis Zone/Central acicular trend
.
This hole tested the two modelled acicular arsenopyrite
trends within the Axis zone and the western-most plane of the Central trends (the 'C' trend). Basalt with
two minor meter-scale intervals of sediment is intersected from the top to bottom of the hole. From 78.08
- 78.87 metres an interval hosting 15% acicular arsenopyrite, 3% blebby arsenopyrite, 3% blocky and
stringers of pyrite, and 2% blocky and blebby pyrrhotite returned 3.80 g/t gold (including 6.80 g/t gold
from 78.08 - 78.44 metres). This interval correlates to the Central C trend, or the intersection of one or
more Axis trends with the Central C trend.
Central Zones
21BSG-010:
Central Zone acicular trend. This drillhole tested the Central Zone B and C acicular
arsenopyrite trends and intersected variably textured and altered basalt throughout. At 16.00 - 17.00
metres depth, the Central B plane is interpreted to be intersected as a brecciated structure which
returned a modest, but relatively elevated, gold value of 0.42 g/t over 1 metre. The C plane is intersected
from 91.00 - 94.00 metres as a brecciated and highly strained interval of fine-grained basalt, with strong
silicification and bands of biotite and chlorite alteration, with 10% acicular arsenopyrite, 4% pyrrhotite,
3% chalcopyrite, and 3% pyrite. The interval grades 5.21 g/t gold over 3 metres. This interval
corresponds with a transition from high-Ti basalt outside of the anomalous gold zone to low/moderate-Ti
basalt from 92.00 - 94.00 metres. From 156.00 - 157.00 metres, 1.94 g/t gold over 1 metre is
intersected, corresponding with a new plane of interest.
21BSG-011:
Central Zone acicular trend. This drillhole tested the Central A, B, and C planes, and
intersected variably textured basalt with minor sediment throughout. From 20.00 - 21.12 metres the
Central A plane was intersected in basalt, grading 1.08 g/t gold over 1.12 metres, and correlating with a
transition from moderate-Ti to low-Ti basalt. The Central B plane was not intersected or not mineralized.
At the predicted depth, basalt is strongly altered (variably bleached from 113 - 124 metres, with 5%
chaotically oriented mm-scale quartz-carbonate-Fe oxide veinlets). The Central C plane is intersected
between 192.74 - 198.40 metres. The gold grade is low, but relatively elevated (0.35 g/t over 1 metre
from 192.21 - 193.21 metres; 0.69 g/t over 1.2 metres from 197.20 - 198.40 metres). A sedimentary unit
intersected just above the weakly anomalous basalt intersection has accommodated ductile (folded
primary mica and chlorite) and brittle (two intervals of fault gouge at 10 cm and 21 cm wide) strain.
21BSG-012:
Central Zone acicular trend. This hole tested all three Central planes. It is collared in
gabbro which extends for ~14 metres followed by a ~15 metre interval of sediment then basalt for the
rest of the hole, with one ~30 metre interval of gabbro from 247.80 - 276.10 metres. None of the planes
of interest are well expressed. Intervals of high strain and brecciation, sometimes with fault gouge, may
be the expression of the Central planes in this drillhole. Not corresponding to a known zone, relatively
elevated gold at 0.27 g/t over 1.07 metre occurs from 15.00 - 16.07 metres at the margin of a fine-
grained basalt and it's lower, faulted contact with sediment. The basalt-sediment contact is mineralized
in other target areas.
The predicted depth of the Central A plane coincides with a basalt and its lower contact with a gabbro at
247.80 metres; this contact is marked by a highly strained mineralized zone from 242.24 - 242.60
metres comprising 6% pyrrhotite and 4% pyrite. The interval from 386.18 - 393.40 metres contains a 10
cm wide interval of brecciation within a high strain zone and up to 5% pyrrhotite-pyrite, and a 55 cm wide
interval with moderate fault gouge and several fractures. No anomalous gold values were returned, but
the interval is at the correct depth to correspond with the Central C plane.
21BSG-014:
Central Zone acicular trend. This drillhole targeted the three Central planes. Like hole
21BSG-012, it is collared in basalt, and intersects thin intervals of gabbro then sediment at the top of
hole, then basalt for the remainder of the hole. Two intervals with anomalous gold correspond to the
Central B and C planes. From 345.12 - 346.12 metres, 1.18 g/t gold is intersected over 1 metre; from
358.58 - 362.62 metres, 2.72 g/t gold is intersected over 4.04 metres.

2021 Exploration Program
Blue Star initiated its 2021 exploration program on June 23 with a geophysics campaign, a drill
campaign starting on July 16
th
, and surface exploration on August 1
st
and successfully completed all
phases of the program in September.
The Exploration campaign evaluated several high priority targets in the area of the known high-grade
Flood Zone Gold Deposit on the Ulu Project, and on high potential targets along the Ulu fold hinge.
Numerous priority targets exist along the 5 km long Ulu Anticline which extends from the Flood Zone
Deposit onto the contiguous Hood River Project up to the North Fold Nose Zone.
Targets considered high priority on the Hood River and Roma Projects had basic initial exploration
campaigns to better understand host geology, confirm structures and existing anomalous zones and
undertake initial geochemical surveys to determine potential to generate additional targets of interest.
Objectives of the 2021 program include better understanding the controls of higher-grade zones within
the hosting structures, evaluating additional structures on and adjacent to the Ulu fold hinge, and defining
additional targets for potential near-term discovery.
The balance of the assay results from the program will be reported as they are received. The slow
turnaround of assays results from the lab is an issue facing the entire sector due to covid-related
disruptions and the high level of mineral exploration in Canada.
Technical Disclosure
Full collar tables and assay tables will be made available on the website in due course. Core samples
were cut by core saw with one half of the core retained and the other half sent for analysis. Samples are
being prepared by ALS Yellowknife-Geochemistry and being analyzed at ALS Global, North Vancouver.
Gold analysis is by fire assay using ALS code Au-AA26 and multielement analysis by code ME-MS61.
Control samples include a crush duplicate every 20 samples; certified reference material is being
inserted once every ten samples. Reported assay intervals are uncapped, use a minimum 1 g/t gold
assay cut off with the inclusion of up to 2 metres of material below cut-off. True widths for all but the Flood
Zone are not known due to lack of drilling and may range from 90% to 95% of drilled lengths.
