TORONTO, Ontario — October 29, 2026 – TheNewswire — LAURION Mineral Exploration Inc. (TSX-V: LME | OTC: LMEFF | FSE: 5YD) (“LAURION” or the “Company”) is pleased to report assay results from drill holes LBX26-113, LBX26-114A, LBX26-115, LBX26-116, LBX26-117 and LBX26-121, from its 2026 Phase 1 diamond drilling program at its 100%-owned Ishkōday Gold and Polymetallic Project (“Ishkōday Project”), located approximately 220 km northeast of Thunder Bay and 28 km northeast of Beardmore, Northwestern Ontario.
Building on the drilling program to date, LAURION increased its planned Phase 1 drilling from 3,865 metres to 5,605 metres across 22 drill holes. The expanded program is being informed by SRK Consulting’s independent structural gap analysis of the A-Zone, which identified five priority target areas where additional drilling may address key gaps in the existing drill database and further strengthen the geological understanding of the A-Zone. LAURION is using this framework, together with ongoing drill results, to prioritize near-term drilling as it continues to systematically advance its exploration of the A-Zone , with the objective of validating its geological interpretation and supporting the evaluation of a potential maiden Mineral Resource Estimate (“MRE”). Additional targets, sequencing and timing remain subject to, among other things, ongoing results and available financing.
Cynthia Le Sueur-Aquin, President and CEO, commented: “ LBX26-117 returned 1.80 metres grading 17.10 g/t gold, including 0.80 metres at 31.50 g/t gold, together with a broader 10.05-metre interval of gold-bearing polymetallic mineralization deeper in the hole. LBX26-121, drilled from the same collar at a shallower angle, intersected gold at several levels, including 5.20 metres grading 1.067 g/t gold with 1.11% zinc, and LBX26-116 returned 2.80 metres grading 2.261 g/t gold. This drilling is designed to address the specific gaps identified by SRK Consulting, improve our understanding of the continuity and geometry of mineralization between drill holes, and build a reliable technical foundation at the A-Zone. We will continue to let the data guide our next steps. ”

LBX26-113 – Interpretation
LBX26-113 was designed as a twin of historical hole 92-65 to verify previously reported high-grade gold and polymetallic mineralization. The new assays returned lower grades than the historical results. The Company will evaluate the implications for the historical drill database for this hole and their geological interpretation.

Note: All core lengths are drilled thicknesses; true widths have not yet been determined. Intervals are calculated using a nominal cut-off and may include internal dilution; “including” intervals are sub-intervals of higher grade contained within the reported interval.
Sampling and QA/QC Protocols
All drill core is transported and stored inside the core logging facility located at the Ishkōday Project in Greenstone, Ontario.
LAURION employs an industry standard system of external standards, blanks and duplicates for all of its sampling, in addition to the QA/QC protocol employed by the laboratory. After logging, core samples were identified and then cut in half along the core axis in the same building and then zip tied individually in plastic sample bags with a bar code. Approximately five or six of these individual bags were then stacked into a “rice” white material bag and stored on a skid for final shipment to the laboratory. All core samples were shipped to the ALS Global Geochemistry facility in Thunder Bay, Ontario, where they were prepared, and the resulting pulps were analyzed by ALS Global Analytical Lab in North Vancouver, British Columbia. ALS is independent of LAURION. Samples are processed by 4-acid digestion and analyzed by fire assay on 50 g pulps and ICP-AES (Inductively Coupled Plasma – Atomic Emission Spectroscopy).
Over limit analyses are reprocessed with gravimetric finish. A total of 5% blanks and 5% standards are inserted randomly within all samples. 5% of the best assay result pulps were sent for re-assays. All QA/QC results were verified, and no contamination or bias was observed. The remaining half of the core, as well as the unsampled core, is stored in temporary core racks at the core logging facility in Greenstone before being moved to the core storage facility at the Ishkōday Project.
QA/QC review of standards and duplicates indicates analytical results are reliable. One zinc standard adjacent to a high-grade zinc interval returned elevated values consistent with expected analytical behaviour following high-grade samples.

About LAURION
LAURION Mineral Exploration Inc. is a mid-stage Canadian mineral exploration company, focused on advancing the 100%-owned Ishkōday Gold and Polymetallic Project in Northern Ontario.
The Ishkōday Project covers approximately 57 km² within the Beardmore–Geraldton and Onaman–Tashota Greenstone Belts and hosts a single 6.0 km by 2.5 km mineralized corridor. Historical and modern exploration programs have completed over 100,000 metres of drilling, confirming a large and evolving gold-rich polymetallic mineral system.
LAURION’s strategy emphasizes disciplined, data-driven exploration, systematic technical advancement, integrated geological modelling, and responsible capital allocation. The Company is focused on strengthening geological confidence, expanding the scale of the mineral system, and positioning the project for a potential future MRE.
LAURION continues to evaluate opportunities that may enhance project development flexibility, including potential non-dilutive initiatives such as the evaluation of historical surface stockpile processing. The Company’s objective is to build technical clarity, scale, and long-term project value before monetization, with the aim that future development decisions or strategic opportunities are supported by strong geological foundations and reduced execution risk.
Cynthia Le Sueur-Aquin, President and CEO of LAURION, is the Company’s largest shareholder, holding 17,221,306 common shares, reflecting strong alignment between management and shareholders.
