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.
