Campaign

TORONTO, Ontario – September 5, 2025 – LAURION Mineral Exploration Inc. (TSXV: LME |

OTCPINK: LMEFF) (“LAURION” or the “Corporation”) is pleased to provide this corporate

update on its previously announced advisory engagements, exploration progress, and

investor outreach initiatives. Reference is made to the Corporation’s press releases dated

Advisory Network Expansion

Amid growing shareholder interest and evolving market access strategies, LAURION has

expanded its strategic advisory network. In addition to its longstanding engagement with

US Capital Global Partners LLC (“USCGP”), the Corporation has retained three additional,

non-exclusive advisory teams. These engagements are consistent with the Corporation’s

objective of exploring opportunities and potential transactions that are strategically

beneficial to the Corporation and its shareholders. Importantly, LAURION has structured

this network of advisors, including USCGP and Oak Hill Financial Inc. (“Oak Hill”), in a

deliberate and coordinated manner to complement one another’s strengths , and to

reflect the realities of tod ay’s evolving capital markets landscape. By integrating the

three advisory groups and USCGP’s global reach with Oak Hill’s institutional and retail

brokerage access, L AURION aims to establish a multi-layered approach to enhancing

investor access and engagement of potential partners and stakeholders in pursuit of

strategic alternatives.

Advancing the Ishkõday Exploration Program

LAURION maintains disciplined and systematic advancement of its flagship 57 km²

Ishkõday Project, located 220 km northeast of Thunder Bay, Ontario.

Highlights from the ongoing 2025 exploration campaign include:

• Completion of deep -penetrating DCIP and 3D Magnetotelluric (MT) surveys,

enabling refined structural targeting down to ~2.5 km, deepening the geological

understanding of fault zones, shear corridors, and mineralizing systems.

of 9.16 g/t Au over 0.80 m at Sturgeon River. Partial results from the fourth hole are

pending. (See the Corporation’s press release dated August 19, 2025.)

• Trenching and channel sampling at Twin Falls / Cyril Knight have identified highly

prospective mineralization, with assay turnaround initially fast and now averaging
