Ms. Cynthia Le Sueur-Aquin reports LAURION EXPANDS ADVISOR NETWORK AND ADVANCES ISHKODAY DRILLING CAMPAIGN Laurion Mineral Exploration Inc. has provided 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 Aug. 19, 2025, June 2, 2025, May 27, 2025, and May 8, 2025. Advisory network expansion Amid growing shareholder interest and evolving market access strategies, Laurion has expanded its strategic advisory network. In addition to its long-standing engagement with U.S. Capital Global Partners LLC, 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 advisers, including USCGP and Oak Hill Financial Inc., in a deliberate and co-ordinated manner to complement one another's strengths and to reflect the realities of today's evolving capital market landscape. By integrating the three advisory groups and USCGP's global reach with Oak Hill's institutional and retail brokerage access, Laurion aims to establish a multilayered approach to enhancing investor access and engagement of potential partners and stakeholders in pursuit of strategic alternatives. Advancing the Ishkoday exploration program Laurion maintains disciplined and systematic advancement of its flagship 57-square-kilometre Ishkoday project, located 220 kilometres northeast of Thunder Bay, Ont. Highlights from the continuing 2025 exploration campaign include: Completion of deep-penetrating DCIP and 3-D magnetotelluric surveys, enabling refined structural targeting down to approximately 2.5 km, deepening the geological understanding of fault zones, shear corridors and mineralizing systems; A 7,000-metre diamond drill program launched in late May, targeting both the Brenbar and Sturgeon River mine areas; Completion of approximately 85 per cent of the planned drill metres with just two drill holes remaining; Assays for the first three drill holes have been released, including a notable result of 9.16 grams per tonne gold over 0.80 m at Sturgeon River; partial results from the fourth hole are pending (see the corporation's press release dated Aug. 19, 2025); Trenching and channel sampling at Twin Falls/Cyril Knight have identified highly prospective mineralization, with assay turnaround initially fast and now averaging six weeks; All assay results will be disclosed by the corporation in a timely manner, upon receipt and validation. Looking ahead and shareholder guidance Laurion reaffirms that any material information and developments will be communicated promptly, consistent with applicable disclosure requirements. In the meantime, shareholders are encouraged to respect channel integrity and refrain from speculating on social media, which may negatively affect the share price and delay the effective execution of any potential strategic initiatives. The corporation appreciates shareholders' patience and trust. The board and management continue exerting significant effort, in consultation with its diverse advisers, to maximize shareholder value.
