LAURION Launches 1,700-Metre Follow-Up Drill Program to Delineate

and Expand Near-Surface Gold and Base-Metal Zones at Ishkōday

Toronto, Ontario – October 28, 2025 – LAURION Mineral Exploration Inc. (TSX.V: LME | OTC:

LMEFF I FSE: 5YD ) (“LAURION” or the “Corporation is pleased to announce the

commencement of a focused 1,700 -metre diamond drill program at its 100% -owned

Ishkōday Project, located approximately 220 kilometres northeast of Thunder Bay, near

Greenstone, Ontario.

This focused program is designed to follow up on previously reported gold - and base

metal-bearing zones Au-(Ag-Zn-Cu) intersected east of the Ishkōday Project, within the

A-Zone and McLeod Zones. These near-surface zones represent compelling opportunities

within the broader Ishkōday system and complement ongoing objectives towards better

definition across the 6.0 km by 2.5 km corridor.

Highlights from Previously Reported Drill Programs

The following intersections, selected for context, collectively demonstrate the presence

of a broader and continuous gold and base metal mineralization corridor across the

eastern Ishkōday Project mineral system.

Gold Intercepts (Previously Reported):

• LBX20-002: 125.90 m to 128.52 m — 2.62 m @ 11.98 g/t Au

• LBX12-010: 46.16 m to 59.00 m — 12.84 m @ 3.31 g/t Au

• LBX21-047: 160.00 m to 164.00 m — 4.00 m @ 2.53 g/t Au

• LBX22-065: 175.30 m to 178.10 m — 2.80 m @ 2.12 g/t Au

• LBX22-089: 72.00 m to 73.05 m — 1.05 m @ 5.91 g/t Au

• LBX12-006: 138.80 m to 140.05 m — 1.25 m @ 4.24 g/t Au

• LBX12-008: 64.00 m to 64.50 m — 0.50 m @ 7.13 g/t Au

Gold-Base Metal Intercepts (Previously Reported):

• LBX20-001: 116.96 m to 141.50 m — 24.54 m @ 0.67 g/t Au, 6.40 g/t Ag and 1.50 % Zn

• LBX20-003: 130.85 m to 194.78 m — 63.93 m @ 0.58 g/t Au, 6.10 g/t Ag and 1.92 % Zn

• LBX20-005: 212.27 m to 213.67 m — 1.40 m @ 5.93 g/t Au, 97 g/t Ag and 8.42 % Zn

• LBX20-006: 81.38 m to 92.20 m — 10.82 m @ 0.65 g/t Au, 3.89 g/t Ag and 1.09 % Zn

(including 1.25 m @ 1.43 g/t Au and 5.30 % Zn)

• LBX20-010: 67.10 m to 67.80 m — 0.70 m @ 15.6 g/t Au, 73 g/t Ag and 14.5 % Zn

Channel samples include 7.50 m @ 0.90 g/t Au, 35 g/t Ag, 0.53 % Cu; and 5.71 % Zn and

1.11 m @ 4.97 g/t Au, 8.00 g/t Ag and 1.35 % Zn- 445496E 5512267N.

All technical results referenced below have been disclosed in prior LAURION news releases available on

www.laurion.ca and on SEDAR+. Please refer to press releases dated 24 September 2019, 18 October

2019, 25 October 2019, 29 May 2020, 24 June 2020 and 15 July, 2022

The A-Zone and McLeod Zone remain under-explored areas, hosting consistent gold and

zinc-rich mineralization within sheared, sulphide rich and quartz -veined volcanic

sequences. Together with the Sturgeon River Mine and Brenbar corridors, these areas

define a 6.0 km by 2.5 km kilometre-long structural trend that remains open at depth.

“This is an exciting, unanticipated addition to our 2025 exploration plans ,” said Cynthia

Le Sueur -Aquin, President & CEO of LAURION . “While our principal focus remains the

Sturgeon River Mine and Brenbar corridors, this targeted program also reflects the

growing importance of the A-Zone and McLeod Zone in shaping Ishkõday Project’s near-

surface gold and base metal potential. Building upon current technical input of our

evolving 3D model, we’re laying the groundwork for future resource definition and

valuation growth across multiple zones.”

Next Steps and 2026 Exploration Objectives

Drilling under the current 1,700-metre follow-up program is scheduled to commence in

late October 2025, with assay results released as will be received. All data will be

incorporated into LAURION’s evolving 3D geological model to refine targeting across

the A-Zone, McLeod Zone, and Sturgeon River Mine and Brenbar areas.

Looking ahead to 2026, LAURION plans an expanded 7,000 – 10,000 metre multi-phase

drill campaign with objectives to advance near-surface resource definition, drill deeper

extensions beneath the Sturgeon River and Brenbar mine as areas, the east side of the

Ishkōday Project and expand structural and geochemical coverage.

This next-phase campaign will provide the technical foundation for LAURION’s future

resource-growth and valuation-enhancement strategy is designed to leverage and

position the Ishkōday Project for future resource definition and development milestones.
