Val-d'or Mining Exploration Update

Executive Summary

• The 2025 diamond drilling program on the Perestroika Prospect intersected several high‑grade gold zones, including a standout 0.50 m @ 107.50 g/t Au (PE‑25‑019) and 0.50 m @ 73.20 g/t Au (PE‑25‑020).
• Twelve holes totaling 5,004 m were completed at a cost of US$0.84 M, expanding the known mineralized corridor southeast, northwest and south of previous drill targets.
• Eldorado Gold retains a 30 % option interest; to maintain its option it must spend $10.5 M by the fifth anniversary and will pay $50,000 annually until exercised.

Key Details

• Program Scope: 12 holes (PE‑25‑009 to PE‑25‑020), 5,004 m drilled using two rigs; budget US$0.84 M.
• High‑Grade Intersections:
• PE‑25‑019 – 4.60 m @ 12.35 g/t Au (269.40–274.00 m) with 0.50 m @ 107.50 g/t Au at 270.00 m.
• PE‑25‑020 – 0.50 m @ 73.20 g/t Au at 38.10 m; additional 2.20 m @ 1.97 g/t Au (54.30–56.50 m).
• PE‑25‑013 – 1.30 m @ 46.39 g/t Au (29.70–31.00 m).
• Other Notable Intersections (>1 g/t Au):
• PE‑25‑014 – 18.40 m @ 1.28 g/t Au (145.60–164.00 m).
• PE‑25‑015 – 3.00 m @ 7.48 g/t Au; 5.55 m @ 4.37 g/t Au; multiple high‑grade inclusions (e.g., 0.55 m @ 37.00 g/t Au).
• PE‑25‑016 – 1.80 m @ 5.65 g/t Au with 0.80 m @ 10.55 g/t Au.
• PE‑25‑017 – 0.80 m @ 19.65 g/t Au.
• Geology: Mineralization hosted in flat extensional quartz‑ankerite veins/veinlets, associated with disseminated pyrite and sericite alteration; situated between two third‑order shear zones within a felsic tonalitic to dioritic dyke swarm.
• Option Agreement (Eldorado Gold):
• Eldorado may acquire an additional 40 % interest in the Perestroika property (currently 70 % held by Val‑d’Or, 30 % by Eldorado).
• Minimum spend requirement: $10.5 M before the fifth anniversary of condition satisfaction.
• Annual payment to Val‑d’Or: $50,000 until option exercised; joint‑venture agreement to follow upon exercise.
• Qualified Person: Glenn J. Mullan, P.Geo., President & CEO, reviewed and approved technical information per NI 43‑101.
