Blue Star Reports High-grade Surface Samples
from Nutaaq, Axis and Twilight Drill Targets;
597 g/t and 134 g/t Au Returned from Nutaaq
Vancouver, British Columbia--(Newsfile Corp. - August 12, 2025) -
Blue Star Gold Corp. (TSXV: BAU)
(OTCQB: BAUFF) (FSE: 5WP0) ("Blue Star" or the "Company")
, a leading explorer in Canada's
North, announces the completion of the pre-drilling Phase I Surface Exploration Program at its projects
located in the High Lake Belt, West Kitikmeot Region of Nunavut (Figure 1).
Blue Star's field-based surface exploration program was initiated in June 2025 and consisted of work
efforts to move targets toward drill-readiness. Additional geophysical surveys were conducted to assess
under-evaluated areas and resolve targets at lower levels of confidence in the target pipeline and
develop potential new targets.
Highlights:
Nutaaq Zone sampling returned 597 and 134 grams per tonne gold ("g/t Au") in visible
gold-bearing quartz veining
Sampling returned 12.2 and 6.64 g/t Au at the Alone vein (~500 metres southeast in the
Nutaaq Zone)
Samples along the up-dip projection of the Axis Zone Induced Polarization anomaly
returned 19.4, 18.8, 10.9, and 7.68 g/t Au
Sampling at the East Limb targets returned 26.4, 17.8, 12.4, and 12.2 g/t Au
Initial sample returns for the South-Twilight target include 29.2, 17.3, 16.1, 14.6, 12.0 and
11.6 g/t Au
Blue Star's Ulu Camp is the only active airstrip-supported camp in the High Lake Belt. It has become the
locus of support for activities being undertaken by West Kitikmeot Resources Corp on the proposed
Grays Bay Road and Port Project, and for exploration work being undertaken by two other large
landholders in the Belt.
Completed & Ongoing Field Activities
Completed - Ground-based electromagnetic surveying using the Loupe-EM system, totaling 138
line-kilometres (East Limb, Gabbro Breccia, West Lake, Contact, Bizen, and North Fold Nose)
Completed - Detailed mapping and sampling of targets within 1,000 metres of the Flood Zone
deposit
Ongoing - Exposure and power-washing of surface Flood Zone mineralisation for detailed
structural mapping and sampling
Ongoing - Lithogeochemical surveys to further define detailed stratigraphy and resolve priority
targets
"The field results received to date provide excellent support for our drill targeting process. Broad
geophysical anomalies hosting strong field sample results along with advancing geological
understanding have built priority targets ready for drill testing,"
said Grant Ewing, CEO of Blue Star
,
"The strong drill targets in the vicinity of the Flood Zone deposit could have a significant impact on
resource development plans in the future. The second phase of the exploration program, scheduled
to commence shortly, will entail drill testing several priority targets. We are looking forward to
continuing to advance our highly prospective properties to evaluate their full potential."
Discussion of Phase I of the 2025 Exploration Program
Ground-based time domain walking electromagnetics surveying known as Loupe-EM was undertaken in
2024. This season the Loupe-EM was again deployed expanding the grids to cover ~7 km2
encompassing the northern part of the Ulu Fold, the Interlake area, and the East limb. Following up on
anomalies from 2024 indicated that the Loupe-EM system has the potential to identify high
concentrations of sulphides associated with quartz veining, similar to the polymetallic mineralization
intersected in the Nutaaq deposit area. Field evaluation located numerous gossanous quartz showings,
all with variable amounts of pyrrhotite, pyrite and chalcopyrite in areas of moderate to strong conductivity
as indicated by the Tau response of the Loupe-EM data. Samples from the
Nutaaq Zone
have returned
1.16 g/t Au to 597 g/t Au
(four samples). All samples from the Loupe-EM anomalies are pending
(Figure 2).
Samples collected from the
East Limb
targets, which are not hosted in the most prospective lithology
based on lithogeochemical mapping, still returned strong assay results ranging from
0.19 g/t Au to 26.4
g/t Au
(eight samples). More work is needed to better understand the controls on this mineralisation.
Field review of the projected up-dip induced polarisation chargeability anomaly identified in the
2023/2024 surveys followed a trace of alteration along the interpreted
Axis Zone
. Sampling returned a
range of results from
0.38 g/t Au to 19.4 g/t Au
(seven samples) along 260 metres of strike. The higher-
grade samples occur in the southeast portion of the trend which is hosted in the preferred high iron-high
titanium tholeiitic basalt unit of interest. This unit is modeled as northwest plunging suggesting that the
moderate grade samples in the overlying basalt may be indicative of stronger mineralisation down dip
where the mineralised corridor intersects the unit down plunge.
Lithogeochemical mapping focused on the
South-Twilight Zone
indicates a complex folding pattern in
the West limb of the Ulu Fold not observed in the East limb. The South Zone appears to occur in narrow
strained alteration zones associated with quartz veining and acicular arsenopyrite hosted within both the
more prospective basalt unit and the overlying basalt unit. The Twilight Zone occurs with similar alteration
and mineralisation associations however it is hosted entirely within the more prospective basalt unit.
Initial samples across the full zone returned values ranging from
detection limit to 29.2 g/t Au
(29
samples; mean 6.11 g/t Au); many sample results are pending.
An overburden-covered section of the Flood Zone has been mechanically stripped and power-washed in
preparation for detailed structural mapping and channel sampling. The area is approximately 15 metres
x 25 metres and is tied to outcrop exposures. The exposed mineralisation is expected to provide
additional confidence in modelling mineralisation right to the bedrock surface and provide improved
structural modeling of the Flood Zone.
Drill Targeting
With assay samples still pending for the Auma prospect initial drill planning has focused on Nutaaq,
Central, Axis and Twilight. Targets are undergoing final prioritisation before drilling. Blue Star is
expecting to complete up to 2,000 metres of drilling on high-priority targets during the current program,
focused on the discovery of new significant zones of mineralisation.
Sampling, Assaying & QA/QC
Blue Star field programs collect a variety of samples; prospecting rock samples are selective by nature,
channel samples are saw-cut samples from outcrop intended to be representative of the exposed
mineralisation, and drill core samples are sawn in half with one half retained as core record and the other
half submitted for analysis.
Blue Star samples are delivered under chain of custody to ALS Geochemistry in Yellowknife, NT for
sample preparation which are then forwarded to ALS Canada Inc. in North Vancouver, BC for final
analysis. Samples are prepared using code PREP-31 (crushing and pulverising) and analysed using
codes Au-AA26 (50-gram fire assay with atomic absorption finish) and ME-MS61 (48 element four acid
digestion with ICP-MS finish). Samples returning >10 g/t Au are reanalysed under code Au-GRA22 (50-
gram fire assay with gravimetric finish). Over limits for non-gold elements are ore grade four acid
digestion with ICP-AES finish. The work is being conducted using industry standard procedures,
including a quality assurance and quality control ("QA/QC") program consisting of the insertion of
certified standards, blanks and duplicates into the sample stream.
