Laurion Mineral Exploration Announces the Completion of 3D DCIP and MT Inversions, Unlocking Deeper Structural Insights at Ishkoday Project

Toronto, Ontario – July 29, 2025 – TheNewswire - LAURION Mineral Exploration Inc. (TSX.V: LME | OTCPINK: LMEFF) (“LAURION” or the “Corporation”) is pleased to announce the successful analysis and completion of a 3D magnetotelluric (MT) inversion over the Ishkōday Project, a significant advancement in subsurface imaging and structural modeling. The final 3D MT resistivity model—reaching depths of up to 2.5 km—demonstrates excellent correlation with known shear zones and fault structures, including the Niish shear zone, and reveals new deep-seated structural features previously undetected by traditional methods. These deep-seated structures are crucial in the circulation of hydrothermal fluids, responsible for the formation of the mineralized zones.    

This inversion provides LAURION with a powerful tool to refine its geological model, better constrain major fault geometries, and identify new deep exploration targets. The results will now be integrated with historical drilling, LiDAR, magnetics, and DCIP datasets to develop a more predictive and structurally informed model of the mineral system. In particular, the new MT resistivity model, when integrated with these other datasets, will allow refinement of the locations and orientations of deep structures under cover. The improved understanding of regional and local structures strengthens LAURION’s strategic targeting and supports its evolution from a near-surface explorer to an advanced, system-scale opportunity.

LAURION’s 7,000-metre drilling program is in progress at the Ishkōday Project. In conjunction with this campaign, the geoscience team is integrating the results of the 3D MT inversion alongside its 2D and 3D DCIP datasets to refine structural interpretations and support confident, deeper drill targeting for subsequent exploration phases. This integrated geophysical framework significantly enhances the technical team’s ability to vector drilling towards prospective mineralized structures at depth. Assay results from the ongoing program will be released once received, validated, and interpreted by LAURION’s technical team.

LAURION remains steadfast in its systematic, data-driven exploration strategy, focused on unlocking the full potential of the Ishkōday Project, and is committed to disciplined, results-oriented advancement and continues to execute on its long-term growth strategy with confidence and precision.

Corporate Update

As a complement to its exploration activities, LAURION continues to actively evaluate potential strategic alternatives and transactional opportunities with the goal of maximizing shareholder value. The Corporation reiterates that it is engaged in ongoing discussions with U.S. Capital Global Partners and other parties in connection with this mandate.

While a large portion of LAURION’s current focus remains on systematically advancing the Ishkōday Project through disciplined exploration, the Board of Directors remains attentive to strategic opportunities that could arise in the short or medium term. These may include acquisitions, mergers, or other value-accretive transactions aligned with LAURION’s long-term objectives.

With a strong foundation of technical progress and expanding geological potential across the 57 km² Ishkōday land package, LAURION is well-positioned for continued strategic interest. Shareholders are reminded that any material developments will be promptly disclosed in accordance with applicable securities laws.
