Blue Star Completes Phase 1 Geophysics and Mobilises Phase 2 Drilling

10 June 2026

Vancouver, British Columbia--(Newsfile Corp. - June 10, 2026) - Blue Star Gold Corp. (TSXV: BAU) (OTCQB: BAUFF) (FSE: 5WP0) ("Blue Star" or the "Company") announces that the Phase I exploration program over its critical mineral targets has been completed, and two drills have been mobilized to initiate the Phase 2 drilling program.

Blue Star is the dominant landholder along the proposed Grays Bay Road and Port corridor in the High Lake Belt, west Kitikmeot Region, Nunavut, Canada (Figure 1). Its properties host the high-grade Flood Zone gold deposit, and numerous gold and critical mineral targets that provide substantial upside potential for resource expansion.

The Phase 1 program focused on advancing targets that are prospective for the discovery of critical mineral-rich volcanogenic massive sulphide (VMS) bodies, all of which are proximal to the known High Lake VMS deposit (Figure 2). The Phase 2 drilling program will commence on high-potential gold targets, followed by drill testing critical mineral targets.

Highlights

  • The Phase 1 ground-based fixed loop electromagnetic (FLEM) surveys refined airborne electromagnetic plate models derived from the 2025 SkyTEM dataset

  • Two FLEM crews completed 64.2 line-kilometres of surveying across nine target grids

  • The high-priority target areas were defined from SkyTEM plate modelling and supplemented by compiled historical datasets

  • FLEM data is being processed to refine plate targets for drill evaluation with plans to drill a minimum of five target areas

  • Two diamond drill rigs have been mobilised to the site to evaluate high-potential gold and critical mineral targets

  • Initial drilling will be undertaken at the Auma Project targeting high-grade gold mineralization associated with conductive alteration corridors, and North Nutaaq to follow up on 7.31 g/t gold over 5.7 metres (and proximal to 115 g/t gold in grab samples) that was drilled in 2025 (News Release dated Oct. 1, 2025)

"The successful execution of our Phase 1 program has delivered promising preliminary data, confirming high-quality drill targets," stated CEO Grant Ewing. "Data processing for our critical mineral targets remains underway as we concurrently prepare to launch the Phase 2 drilling program, which will initially prioritize two prospective gold target areas. 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."
