Exploration Programs

Blue Star Commences Drill Program

Vancouver, British Columbia--(Newsfile Corp. - August 14, 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 start up of the drilling campaign, part of the 2025 Exploration Program at its

projects located in the High Lake Belt, West Kitikmeot Region of Nunavut (Figure 1).

A planned 2,000-metre drill program is designed to evaluate select high-priority targets for their resource

potential. These targets are based on a final field review conducted earlier this season as part of the

Phase I Field Program. The targets were prioritized following detailed mapping, sampling, and

lithogeochemical and geophysical reviews. The geophysical reviews included magnetics, induced

polarisation and Loupe-EM data. Additionally, any logs and core sampling results from previous drilling

that occurred within 2,000 metres of the proposed targets were reviewed.

Completed & Ongoing Field Activities

Pending - Detailed structural mapping and channel sampling of newly exposed Flood Zone at the

surface

Ongoing - Lithogeochemical surveys to further define detailed stratigraphy and resolve priority

targets

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

Completed - Exposure and power-washing of surface Flood Zone mineralisation

"The field team has elevated a series of prospects to drill readiness from our abundant target pipeline

for the current drill program,"

said Grant Ewing, CEO of Blue Star

, "many of these targets are bias

toward proximity to the existing mineral resources, however we are committed to evaluating at least

one high conviction target regardless of location to show the blue-sky potential of Blue Star's

extensive land package."

Discussion of Phase II of the 2025 Exploration Program

Blue Star is expecting to complete up to 2,000 metres of drilling on high-priority targets focused on the

discovery of new significant zones of mineralisation. With assay samples still pending for the Auma

prospect, initial drill planning has focused on Nutaaq, Central, Axis and Twilight. The first drilling will be

undertaken on the Nutaaq zone with discrete targets identified at the visible gold area (NR August 12,

2025), the Alone vein (1.16 g/t to 12.15 g/t Au; NR August 12,2025) and northern Nutaaq structures

(assays pending).

After the initial drill tests at Nutaaq, drilling will test high conviction targets at Axis and Auma, as well as

targets on the South-Twilight Zone, which have recently returned surface sampling values up to 29.2 g/t

Au (NR August 12, 2025)

Nutaaq Drill Target(s)

Nutaaq drilling is targeting select inferred structures based on historical geochemical data, recent

surface follow-up and coincident geophysical anomalies. Targets on this list include the visible gold

showing recently identified (NR dated August 12, 2025), and the Alone vein and North Nutaaq area.

North Nutaaq is an example of the high potential of these targets; prospecting during Phase 1 of the

2025 Exploration Program identified massive pyrrhotite mineralization along with several gossanous

quartz blocks correlating with the Loupe EM Tau anomalies at surface that are traceable for 400 metres.

Several historical grab samples from the area returned gold in rock samples, and a historical soil

sampling program by BHP (circa 1992) highlighted anomalous gold in soils. The initial proposed drill

hole will test three target horizons (Figures 2 & 3).

Axis Target (NR March 18, 2025)

Axis is a historical high-grade target within the inferred axial plane of the ULU anticline with surface

grades up to 35.22 g/t Au. More recent work, including a 2023 Induced Polarisation (IP) survey, resulted

in a chargeability anomaly that outlines an untested target orientation and depth. A derived alteration

model for drill data also highlights the IP trend which is coincident with a structural discontinuity that was

identified using lithogeochemical sampling. Surface mapping identified acicular arsenopyrite and gold

mineralization, along with biotite alteration and brecciation (NR August 12, 2025). The proposed drill

target is shown in Figure 4 below.

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.
