First Drill Results Confirm High-Grade Gold System at Rouyn

FIRST DRILL RESULTS CONFIRM HIGH-GRADE GOLD SYSTEM AT ROUYN

Best Intercept – Astoria:
7.0m @ 16.1 g/t Au at Astoria, including 1.0m @ 78.7 g/t Au

Key Highlights

• Standout Intersections from the 822m results returned:

  • AS-26-778:  3.0m @ 11.4 g/t Au (from 68m) including 1.0m @ 24.6 g/t Au

  • AS-26-779:  7.0m @ 16.1 g/t Au (from 131m) including 1.0m @ 78.7 g/t Au & 1m @ 27.0 g/t

  • AS-26-779:  11.0m @ 2.6 g/t Au (from 149m) – Astoria footwall zone

• The holes were designed to test extensions to mineralisation of the currently modelled orebody, with results confirming continuity of high-grade zones typical of deposits along the Cadillac–Larder Lake Break

• Results represent the first assays from Ardiden’s 2026 drilling program, the first holes representing 882m of the planned 15,000m campaign

• Astoria was selected as the starting point due to its existing resource base and strong potential for down-plunge resource growth

• Mineralisation remains open along strike and at depth across Ardiden’s 6km Rouyn gold corridor

• The project is situated on the Cadillac–Larder Lake Break, one of the most prolific and high-value gold structures in the Abitibi Greenstone Belt
