LAURION Extends High-Grade Zinc-Silver Mineralisation Down-Plunge at A-Zone, Confirms New Garvey Zone Target

(via TheNewswire)   Highlights. Results confirm mineralisation continues to grow at Ishkōday: down-plunge at the A-Zone in LBX26-104, along strike to the northeast at the newly validated Garvey Zone target in LBX26-103 and extending southwest along the McLeod Horizon in LBX26-105. Drilling results for LBX26-104 confirm gold-zinc-silver-copper mineralisation down-plunge of the A-Zone with 11.15m grading 0.393 g/t Au, 6.06 g/t Ag, 0.18% Cu and 1.80% Zn; and gold mineralisation in hole LBX26-105, with 2.00m grading 1.342 g/t Au, including 1.00m grading 2.530 g/t Au alongside a broad polymetallic interval of 14.90m grading 0.125 g/t Au, 4.89 g/t Ag, 0.18% Cu and 0.67% Zn ; and confirms the Garvey Zone geophysical target concept in hole LBX26-103. TORONTO, Ontario — August 5, 2026 – TheNewswire — LAURION Mineral Exploration Inc. (TSX-V: LME | OTC: LMEFF | FSE: 5YD) ("LAURION" or the "Company") is pleased to report assay results from the first three diamond drill holes, LBX26-103, LBX26-104, and LBX26-105, completed as part of the Company's ongoing Phase 1 drilling program at its 100%-owned Ishkōday Gold and Polymetallic Project ("Ishkōday" or the "Project"), located in the Beardmore-Geraldton Greenstone Belt of Northwestern Ontario. The results support management’s view that the A-Zone may have potential to support a future mineral resource estimate (“MRE”) at the A-Zone, extending known mineralisation deeper underground and confirming a new target area along strike. Management Comment “In our view, these three holes are an encouraging start to our 2026 infill program, continuing to confirm and extend mineralisation we already know is here," said Cynthia Le Sueur-Aquin, President and CEO of LAURION. LBX26-104 and LBX26-105 have extended the polymetallic footprint of the A-Zone well down-plunge of historical drilling, and the zinc and silver grades we are seeing there – including over six (6) metres of better than 6% zinc – open up new depth potential for the Project. These results move us closer to our goal of unlocking the A-Zone's first resource. LBX26-103 has validated our geophysical targeting at the Garvey Zone, confirming that the same IP and resistivity signature that defines the A-Zone extends along strike to the northeast. We look forward to continuing to build on these results as the infill program progresses.”     Highlights LBX26-105 (McLeod Horizon / 2015 Abitibi geophysical target, SW of LBX22-080 and LBX22-081): 2.00m grading 1.342 g/t Au, 1.30 g/t Ag, 0.06% Cu and 0.30% Zn from 233.00m to 235.00m, including 1.00m grading 2.530 g/t Au, 2.00 g/t Ag, 0.07% Cu and 0.45% Zn.   14.90m grading 0.125 g/t Au, 4.89 g/t Ag, 0.18% Cu and 0.67% Zn from 298.10m to 313.00m, including 5.50m grading 0.267 g/t Au, 8.63 g/t Ag, 0.29% Cu and 1.06% Zn, and a higher-grade 0.50m interval grading 0.150 g/t Au, 15.60 g/t Ag, 0.33% Cu and 3.49% Zn.   1.70m grading 0.960 g/t Au from 258.00m to 259.70m, including 1.00m grading 1.150 g/t Au.   A narrow, high-grade polymetallic interval of 0.50m grading 0.111 g/t Au, 13.10 g/t Ag, 0.72% Cu and 3.26% Zn from 247.20m to 247.70m.   LBX26-104 (A-Zone down-plunge test): 11.15m grading 0.393 g/t Au, 6.06 g/t Ag, 0.18% Cu and 1.80% Zn from 264.70m to 275.85m, including 5.35m grading 0.662 g/t Au, 8.88 g/t Ag, 0.23% Cu and 3.28% Zn, and including a higher-grade 1.95m interval grading 1.314 g/t Au, 13.43 g/t Ag, 0.41% Cu and 6.34% Zn.   LBX26-104 also returned 7.70m grading 0.207 g/t Au, 3.19 g/t Ag, 0.07% Cu and 1.42% Zn from 283.30m to 291.00m, including 0.50m grading 1.780 g/t Au, 4.80 g/t Ag, 0.10% Cu and 2.02% Zn, and a narrow high-grade interval of 0.50m grading 6.460 g/t Au, 19.00 g/t Ag, 0.89% Cu and 2.32% Zn at 313.00m to 313.50m.   Near-surface polymetallic mineralisation was also intersected in LBX26-104 from 7.50m to 9.90m (2.40m grading 0.417 g/t Au, 4.28 g/t Ag, 0.09% Cu and 1.02% Zn, including 0.90m grading 0.693 g/t Au, 6.70 g/t Ag).   LBX26-104 was collared approximately 166m northwest of historical drill hole 90-47 and approximately 191m northwest of historical drill hole 90-39, extending the tested down-plunge footprint of the A-Zone corridor beyond historical drilling.   LBX26-103 (Garvey Zone IP target): Confirmed the presence of hydrothermal quartz-breccia hosted polymetallic mineralisation coincident with the Garvey Zone chargeability/resistivity anomaly, including 3.75m grading 0.164 g/t Au and 14.41 g/t Ag from 195.20m to 198.95m, and 2.30m grading 0.111 g/t Au and 2.70% Zn from 221.10m to 223.40m, including 1.30m grading 0.137 g/t Au, 7.22 g/t Ag and 3.16% Zn.   Results from LBX26-103 indicate that gold grades within the breccia-hosted polymetallic mineralisation remain low relative to the orogenic quartz-vein style mineralisation that hosts the majority of higher-grade gold at Ishkōday, reinforcing the Company's structural model that these represent distinct mineralising events.  By contrast, the gold intercept in LBX26-105 is consistent with the orogenic, quartz-vein-hosted style, while the broader zinc-silver-copper interval in the same hole reflects the polymetallic system, indicating both mineralising systems are present, and separately identifiable, well beyond the A-Zone itself.     Table 1: LBX26-103 (Garvey Zone IP Target, NE-Extension of the A-Zone) Hole LBX26-103 was designed to test the recently defined Garvey Zone chargeability anomaly (Clearview Geophysics survey line T2; Abitibi Geophysics anomaly I-3 NE), coincident with the projected northeast-extension of the A-Zone mineralised horizon. The hole targeted the center of the chargeability anomaly while simultaneously testing a well-defined magnetic lineament, a geophysical signature the Company interprets as consistent with a sulphide-rich shear zone.

Table 2: LBX26-104 (A-Zone Down-Plunge Test) Hole LBX26-104 was designed to test the down-plunge extension of the A-Zone and was collared approximately 166m to the northwest of historical drill hole 90-47 and approximately 191m to the northwest of historical drill hole 90-39 . Historical holes 90-47 and 90-39, drilled in 1990 to 262.7m and 209.1m respectively (Ontario Geological Survey Assessment File 42E13SE0098), returned no significant results for comparatively shallow depths.  LAURION believes the historic holes did not adequately test the down-plunge extension which is supported by these results from LBX26-104.

LAURION continues to work closely with its laboratory partners to manage this timeline and will provide further updates on drilling and assay results as they become available.   LAURION Unveils SRK’s Clear Roadmap to Maiden Resource at the A-Zone, Ishkōday Project SRK Consulting has completed an independent technical gap analysis review, identifying five specific mapped zones where near-term drilling is expected to prepare LAURION’s A-Zone for its maiden MRE. The A-Zone hosts not one, but two, distinct styles of mineralisation – a zinc-copper-iron- rich polymetallic system layered with a gold-silver system – sitting on top of a drilling database of over 300 holes and nearly 57,000 metres already in hand. Within the main A-Zone shoot, targeted drilling is focused on areas where additional data may support future evaluation of the continuity and extent of known mineralisation.  A second targeted zone requires the twinning of historic holes with new quality-controlled drilling to confirm and potentially extend decades-old partially sampled mineral intercepts. Two more zones are designed to establish the true shape and continuity of the deposit's mineralised shoots, while a fifth zone targets the down-plunge extension of the A-Zone. Collectively, these target areas provide a focused framework and drilling plan for advancing geological knowledge of the A-Zone and evaluating its potential to support a future MRE. With drilling already underway and directly targeting these findings , LAURION is executing a clear path toward its maiden resource. Quality Assurance / Quality Control All drill core is transported and stored inside the core 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 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” material bag for final shipment to the laboratory.   All core samples were shipped to the ALS facility in Thunder Bay, Ontario, which were then prepared by ALS Global Geochemistry in Thunder Bay and analyzed by ALS Global Analytical Lab in North Vancouver, British Columbia. 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% standard are inserted randomly within all samples. 5% of the best assay result pulps were sent for re-assays. All QA/QC were verified, and no contamination or bias have been 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 Beardmore and moved to the core storage facility at the Ishkōday Project.   Note: 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 .
