Blue Star expands Auma property to 11,794 hectares

Executive Summary

• Blue Star Gold Corp. expanded its Auma property in Nunavut from 614 to 11,794 hectares, consolidating a large, underexplored portion of the High Lake volcanic belt.
• The expanded land package captures diverse geological settings, including orogenic gold and volcanogenic massive sulphide (VMS) targets, with multiple high-grade gold and polymetallic trends remaining untested by drilling.
• Following limited historical drilling and significant 2025 surface sampling results (up to 151.5 g/t Au), the company plans a phase 1 diamond drill program in 2026 to test Zones 1, 3, and the newly discovered Penny Lane prospect.

Key Details

• Property Expansion: Auma property increased from 614 to 11,794 hectares in the Kitikmeot region of Nunavut.
• Land Composition: Approximately 4,255 hectares of Crown mineral claims and 7,539 hectares under a mineral exploration agreement on Inuit-owned land.
• Historical Drilling: Only six short holes totaling <350 metres were drilled, intersecting 15.3 g/t Au over 2.6 m (Zone 1) and 2.4 g/t Au over 4.0 m (Zone 2).
• 2025 Surface Sampling: Confirmed property-scale gold mineralization with samples up to 35.3 g/t Au extending 1.4 km from the original showing. Zone 3 hosts the highest-grade surface samples up to 151.5 g/t Au and remains untested by drilling.
• New Prospect Discovery: The Penny Lane prospect, discovered in 2025, returned high-grade polymetallic values of 7.64 g/t Au and 4.2% Cu from surface sampling.
• Geological Context: Original property features vein-hosted gold in mafic volcanic rocks; expanded area includes carbonate-altered shear zones with arsenopyrite and VMS-style Zn/Cu occurrences in the Canoe Lake area.
• Geophysical Data: Multiple generations of EM and magnetic data, including a 2025 SkyTEM heliborne survey, highlight coincident anomalies associated with mapped veining and mineralization.
• 2026 Drill Program: Phase 1 diamond drilling will target Zone 1 (downdip extensions of historical mineralization), Zone 3 (highest-grade surface samples, untested), and Penny Lane (reconnaissance scout hole for Cu-Au mineralization).
• Qualified Person: Darren Lindsay, PGeo, VP Exploration, has reviewed and approved the technical information under NI 43-101.

Notable Quotes

• "Our 2025 results demonstrated the strength and size of the Auma gold system, and the expanded land position allows us to explore it at a scale that reflects its potential," said Grant Ewing, CEO. "The planned 2026 drill program will represent the first modern test of Auma's highest-priority targets."
