TORONTO, Ontario, September 23, 2026 – TheNewswire — LAURION Mineral Exploration Inc. (TSX-V: LME | OTC: LMEFF | FSE: 5YD) (“LAURION” or the “Company”) is pleased to report assay results from drill holes LBX26-109 and LBX26-110 from its 2026 Phase 1 diamond drilling program at its 100%-owned Ishkōday Gold and Polymetallic Project (“Ishkōday”), located approximately 220 km northeast of Thunder Bay and 28 km northeast of Beardmore, Northwestern Ontario.

Phase 1 Drill Program and Progress

Through targeted infill, expansion and exploration drilling, LAURION’s 2026 Phase 1 drill program is designed to systematically advance the A-Zone, which may support the evaluation of a potential maiden Mineral Resource Estimate (“MRE”). LBX26-109 and LBX26-110 tested targets associated with the River Shear, historical gold intercepts and modelled mineralized horizons, providing additional geological information from comparatively underexplored areas of the mineralized system.

LBX26-109 was designed to test an isolated chargeability anomaly in the footwall of the River Shear, while also testing along strike to the northeast of high-grade gold inter
