LAURION Reports 32.47 g/t Gold Over 1.90 m, including 67.8 g/t Gold Over 0.90 m in Channel Sample at Twin Falls, Ishkōday Project

Toronto, Ontario – October 8, 2025 – LAURION Mineral Exploration Inc. (TSX.V: LME | OTC: LMEFF) (“LAURION” or the “Corporation”) is pleased to report results from its recent channel sampling

program from the Cyril Knight Showing, situated at Twin Falls northwest of the historic Sturgeon River Mine within the Ishkōday Project. The Twin Falls property is contiguous to and lies immediately west of the broader Ishkōday Project, which is located approximately 220 kilometres northeast of Thunder Bay, near Greenstone, Ontario.

Channel Sampling Highlights

LAURION’s systematic program has returned high-grade gold values from several key channel intervals, confirming the presence of structurally controlled quartz veining and associated sulfide mineralization in the sheared porphyry host.

⦁ CK-L49: 1.90 m @ 32.47 g/t Au, including 0.90 m @ 67.80 g/t Au

⦁ CK-L55: 0.50 m @ 19.90 g/t Au

⦁ CK-L51: 1.05 m @ 2.43 g/t Au, including 0.55 m @ 4.41 g/t Au

This is the first modern channel sampling program conducted at the Cyril Knight Showing, offering critical validation of historic results while revealing new high-grade zones.

Cynthia Le Sueur-Aquin, President and CEO of LAURION, stated: “These channel sample results from the Cyril Knight Showing are an exciting development for LAURION. They demonstrate that gold-bearing structures, first identified nearly a century ago, remain intact and significantly underexplored. This success further validates our geological model and highlights the potential of the western flank of Ishkōday. LAURION is unlocking new opportunities across this underexplored system.”

Technical Significance

In 2025, LAURION stripped and pressure-washed the Twin Falls outcrop, revealing fresh bedrock exposure suitable for detailed structural mapping and sampling. This work:

⦁ confirms historic reports with modern assay validation;

⦁ provides direct structural and lithological control for ongoing 3D geological modelling; and

⦁ supports the targeting of potential extensions of gold-bearing structures through trenching and drilling.

About the Twin Falls Property

⦁ Acquired in 2023, LAURION’s 10.46 km² Twin Falls Property lies contiguous to the Ishkōday Project, approximately 7 km west of the historic Sturgeon River Mine. The area is underlain by
Archean intermediate to felsic metavolcanic rocks, including feldspar and quartz-feldspar

porphyry, and felsic volcanic breccia, hosting several structurally controlled orogenic gold occurrences. Many of these are stock-related and positioned near granitic and granodioritic intrusions.

⦁ The Cyril Knight Showing was first explored in 1934 by Cyril Knight Prospecting Co. Ltd., where early sampling reported up to 0.64 oz/ton gold (21.94 g/t Au) over 9 inches in a quartz vein. The showing lies within a 60-metre-wide corridor of sheared and sericitized quartz-feldspar porphyry and felsic tuff, striking east-west and dipping steeply south.

A preliminary prospecting program completed in 2024 returned high-grade grab samples, including

73.20 g/t Au, 61.50 g/t Au, 31.4 g/t Ag with 13.10 g/t Au, 132.0 g/t Ag with 4.53 g/t Au; and 125.0 g/t Ag with 3.33 g/t Au. (See the Corporation’s press release dated August 23, 2024.)

These early results confirmed the presence of high-grade gold mineralization at surface and reinforce Twin Falls as a priority area for follow-up mapping, trenching, and potential drilling.
