Aurion Extends the Strike of the Mineralized System by 300 m to 1.4 km at Kaaresselka, Risti Property

Executive Summary

• Aurion Resources reports that drilling at the Vanha prospect (Kaaresselkä area, Risti property) has extended the gold‑mineralized system by ~300 m to a total strike length of 1.4 km and to at least 250 m depth.
• Significant intercepts include 1.07 g/t Au over 9.20 m, 2.85 g/t Au over 4.80 m, and 0.88 g/t Au over 20.30 m, among others across seven holes (total 1,380.8 m).
• The system remains open in multiple directions, with scout holes and heavy‑mineral sampling indicating further potential mineralization west of Vanha.

Key Details

• Drilled Holes: 7 holes (KS25109, KS25110, KS25115, KS25116, KS25117, KS25122, KS25123) totaling 1,380.80 m.
• Key Intercepts:
• KS25116 – 1.07 g/t Au over 9.20 m (75.60‑84.80 m) and 1.20 g/t Au over 10.85 m (109.65‑120.50 m).
• KS25110 – 2.85 g/t Au over 4.80 m (70.50‑75.30 m) and 1.68 g/t Au over 8.10 m (155.10‑163.20 m).
• KS25115 – 0.88 g/t Au over 20.30 m (43.00‑63.30 m), including 2.01 g/t Au over 4.15 m (57.30‑61.45 m).
• System Extension: Mineralized zone now interpreted to extend 1,400 m along strike and ≥250 m depth; open both laterally and at depth.
• Scout Holes (LT25001‑6): Six holes 6.4–8 km west‑northwest of Vanha; three returned gold values up to 0.52 g/t Au, with one hole showing 0.89 g/t Au + 1.55 % Cu over 0.40 m.
• Heavy‑Mineral Sampling: 30 samples processed; Knelson gold grain counts ranged 7–213 grains, with five samples ≥100 grains and eleven ≥50 grains, indicating nearby sources.
• Metallurgical Test Work: Bottle‑roll leach tests on two Vanha samples showed >93.6 % Au recovery, confirming free‑milling nature.
• Geology: Mineralization hosted in highly deformed mafic volcanic/metasedimentary rocks with silica, sericite, albite alteration and minor sulphides (pyrite, chalcopyrite, etc.). Elevated base metals and PGE noted.
• QA/QC: Core sent to ALS labs (Finland, Ireland, Romania); fire‑assay and ICP methods employed; certified standards, blanks, duplicates used per ISO‑compliant protocols.
• Comments: CEO Matti Talikka highlighted the “impressive” growth of the Vanha system and ongoing drilling aimed at higher‑grade zones and further strike extensions.
