 TORONTO, Ontario – September 5, 2025 – TheNewswire - 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  August 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 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 today’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,  LAURION 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:
 
 
 
 Looking Ahead and Shareholder Guidance  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.  
 
  A 7,000 m diamond drill program launched in late May, targeting both the Brenbar and Sturgeon River Mine areas.  
 
  Completion of approximately 85% 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 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 six weeks.  
 
  All assay results will be disclosed by the Corporation in a timely manner, upon receipt and validation.  
 
 
 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  advisors, to maximize shareholder value.
