Blue Star survey outlines new targets at Roma

Executive Summary

• Blue Star Gold Corp. has acquired and released new high-resolution SkyTEM airborne electromagnetic (AEM) and magnetic survey data from its Roma and Auma projects in Nunavut.
• The survey identified multiple compelling critical mineral and gold targets, including new conductive anomalies near the High Lake VMS deposit and extensions of gold mineralization at the Auma property.
• The company plans to conduct follow-up fixed-loop ground EM surveys in spring 2026 and geological mapping in summer 2026, with the ultimate goal of designing an extensive drill program to test these newly defined targets.

Key Details

• Survey Scope: 2,450 hectares (242.6 km) of data collected using the SkyTEM 306HP system across the Roma MEA and Auma target areas.
• Roma Project (Critical Metals):
  • Identified discrete AEM anomalies within 3 km of the High Lake deposit’s West zone massive sulphide lens.
  • High-priority targets identified: Stu, West West, and South zones; moderate priority at Cairo.
  • Stu Prospect: Moderate to strong conductive response; historical grab samples returned 5.96% Cu and 4.76% Cu.
  • West West Prospect: Moderate conductive response; surface gossan assays of 1.64% Cu and 1.10 g/t Au.
  • South Prospect: Strong late-time EM anomaly coincident with magnetic anomaly; massive pyrite lenses mapped at surface.
  • Cairo Area: Most promising surface mineralization; historical samples up to 9.99% Cu; recent 2025 grab samples yielded 7.78% Cu and 4.20% Cu.
• Auma Property (Gold):
  • Survey confirmed geophysical signature associated with known mineralized trends.
  • Recent 2025 surface grab samples from main showing graded 151.5 g/t Au and 125.5 g/t Au.
  • Samples 1.4 km south of main showing returned 35.5 g/t Au.
  • Results suggest potential for significant increase in strike extent of mineralization.
• High Lake Deposit Context:
  • Indicated resource: 7.9 Mt at 3% Cu, 3.5% Zn, 0.32% Pb, 83 g/t Ag, 1.3 g/t Au.
  • Inferred resource: 6 Mt at 1.8% Cu, 4.3% Zn, 0.41% Pb, 84 g/t Ag, 1.3 g/t Au.
• Next Steps:
  • Detailed Maxwell 3-D plate modelling of significant conductors.
  • Follow-up fixed-loop ground EM survey planned for spring 2026 (utilizing lake ice) to refine anomaly locations, including work on the Ataani massive sulphide lens.
  • Geological mapping, prospecting, and sampling program planned for summer 2026.
  • Data will be used to design an extensive drill program.

Notable Quotes

• "The new SkyTEM data has refined our understanding of the geology at both the Roma critical mineral targets and Auma gold targets... These results support our ongoing efforts to advance both critical mineral and gold discoveries across our highly prospective Nunavut projects." — Grant Ewing, CEO
