LAURION Initiates 2025 Drill Campaign at Ishkoday with a 7,000 m Program to

Target Gold-Bearing Veins at Brenbar and Sturgeon River Mine

TORONTO, Ontario – May 8, 2025 – LAURION Mineral Exploration Inc. (TSXV: LME |

OTCPINK: LMEFF) (“LAURION” or the “Corporation”) i s p l e a s e d t o a n n o u n c e t h e

commencement of an approximate 7,000 metre diamond drill program at its 100%-

owned Ishkoday Project located 220 km north of Thunder Bay, northwestern Ontario. The

2025 drill campaign, scheduled to commence in the last week of May, will focus on

advancing the Corporation’s understanding of the mineralized system at the historic

Brenbar Mine area and continue expanding the Sturgeon River Mine corridor, supported

by the completion of deep-penetrating DC IP and Magnetotelluric (MT) geophysical

surveys.

“The integration of geophysics, historic da ta and structural mapping allows us to

advance multiple high-confidence targets in parallel, ” said Cynthia Le Sueur-Aquin,

President and CEO of LAURION. “We believe this program will unlock meaningful

extensions at both Brenbar and Sturgeon Rive r, with the potential for new discoveries at

depth and along strike.”

This drill program forms a central pillar of LAURION’s ongoing exploration strategy to

realize the full potential of the Ishkoday gold-polymetallic mineral system.

Targeting High-Grade and Broader Mineralized Zones at Brenbar

The drill program will follow up on multiple historical higher-grade gold intercepts at

Brenbar, including:

 69.1 g/t gold over 0.3 m and 20.9 g/t gold over 1.0 m in BB10-19

 10.2 g/t gold over 0.4 m in BB10-22

 6.6 g/t gold over 0.5 m in BB10-20

 3.28 g/t gold over 0.7 m in BB10-23

Importantly, the 2010 drill campaign conducted by Kodiak/Prodigy Gold ( Report on the

Brenbar Property – 2020 Diamond Drilling Program – Jamie Light and Jerry Solomon - 2020)

also identified broader gold-bearing zones with stacked veining and pervasive alteration,

including:

 2.90 m averaging 0.533 g/t Au in BB10-20

 10.85 m averaging 0.280 g/t Au and 2.50 m averaging 1.293 g/t Au in BB10-24

 3.9 m averaging 0.541 g/t Au in BB10-26

 5.10 m averaging 0.5786 g/t Au in BB10-23 including 0.70 m averaging 3.280 g/t Au

 6.3 m and 8.20 m zones with grades of 0.511 g/t Au and 0.657 g/t Au, respectively,

in BB10-27 including grades up to 3.26 g/t Au

These zones are hosted in sheared felsic to intermediate volcanic and volcaniclastic

rocks with disseminated sulphides and quartz-carbonate stockwork veining.

Geophysics Refines Deeper and Structural Targets

LAURION recently completed a combined 2D Deep Induced Polarization (DCIP) and

Magnetotelluric (MT) geophysical survey over the Brenbar and Sturgeon River Mine areas.

The surveys mapped deep resistivity and chargeability contrasts to depths of up to 1,000

m, helping delineate:

 Silicified structural corridors linked to quartz veins.

 Disseminated sulphide zones below known surface and shallow intercepts.

 Subsurface features along and below the North and South Brenbar faults and the

Sturgeon River Shaft.

Expanded Drilling at the Sturgeon River Mine

In parallel with the Brenbar drilling, LAURION will conduct a drill campaign at the Sturgeon

River Mine, targeting:

 Deeper mineralized structures beneath historic underground workings.

 In-fill drilling to improve continuity of known gold zones.

 Strike extensions to the north and south of the main mine area.

 New zones to the northwest, including follow-up on the M24 and M25 vein systems,

which host multiple gold-bearing quartz structures in proximity to the Sturgeon

historical shaft.

The Corporation looks forward to continuing its disciplined exploration efforts and

advancing its long-term growth strategy.
