Blue Star Completes Phase 1 Geophysics and Mobilises Phase 2 Drilling

Executive Summary

• Blue Star Gold Corp. has completed its Phase I exploration program and mobilized two diamond drill rigs to initiate Phase II drilling across its Nunavut land package.
• Phase I focused on ground-based FLEM geophysical surveys across nine target grids, refining 2025 SkyTEM airborne data to identify high-priority conductive targets for gold and critical minerals.
• Phase II will initially prioritize high-potential gold targets at the Auma Project and North Nutaaq, followed by critical mineral VMS targets, with plans to drill a minimum of five target areas.

Key Details

• Drilling Mobilization: Two diamond drill rigs have been mobilized to the site to evaluate high-potential gold and critical mineral targets.
• Phase I Geophysics: 64.2 line-kilometres of ground-based FLEM surveys were completed across nine grids (Ataani, West West, Gap, Stu, South, Juno N., Juno S., Cairo E., Cairo S.) using 100m line spacing and 25m station spacing.
• Data Processing & Drill Plans: FLEM data is being processed to refine plate targets for drill evaluation; plans include drilling a minimum of five target areas.
• Gold Target - Auma Project: Initial drilling will target high-grade gold mineralization associated with conductive alteration corridors, following surface mapping, sampling, and historical geophysics compilation.
• Gold Target - North Nutaaq: Priority drilling will follow up on a 2025 intersection of 7.31 g/t Au over 5.7m; parallel surface structures returned >100 g/t Au. Targets are located 600m north of the Flood Zone Deposit and are inferred to be ~300m in strike length.
• Additional Gold Exploration: ~800m strike length gossanous trend (South Contact-Contact-Zebra-Apex targets) will undergo field evaluation; historical shallow drilling (~2,000m) revealed unsampled sulphide-rich veining.
• Flood Zone Deposit: Additional surface exposure work planned below thin glacial till cover to improve mapping, channel sampling, resource extension understanding, and future mining approach planning.
• Critical Mineral/VMS Targets: Includes Ataani massive sulphide body (17.1m MS, incl. 2.0m @ 10.95% Zn, 3.5m @ 1.46% Cu) and Sand Lake target (up to 2.71% Cu over 21m). Nearby High Lake deposit hosts Indicated (7.9Mt @ 3% Cu, 3.5% Zn, 0.32% Pb, 83 g/t Ag, 1.3 g/t Au) and Inferred (6Mt @ 1.8% Cu, 4.3% Zn, 0.41% Pb, 84 g/t Ag, 1.3 g/t Au) resources.
• Technical Qualification: Darren Lindsay, P. Geo., VP Exploration, is the Qualified Person under NI 43-101 who reviewed and approved the technical information.

Notable Quotes

• CEO Grant Ewing: "The successful execution of our Phase 1 program has delivered promising preliminary data, confirming high-quality drill targets... This sets the stage for a high-impact year, characterized by a comprehensive exploration campaign designed to maximize discovery potential and accelerate resource expansion across multiple high-priority zones."
