LAURION Extends Drilling into Untested Floor Linking Brenbar and Sturgeon River Mine Corridors at Ishkoday

(TheNewswire)

Toronto, Ontario November 25, 2025 TheNewswire – Laurion Mineral Exploration Inc. (TSX.V: LME | OTC: LMEFF) (“LAURION” or the “Company”) is happy to announce encouraging outcomes from its 7,700-metre Summer season 2025 drill exploration program on the 100%-owned Ishkõday Challenge, positioned 220 km northeast of Thunder Bay in Greenstone, Ontario. The primary 5 drill outcomes had been introduced within the Company’s press releases dated August 19, 2025 and September 23, 2025, respectively, which focused the high-grade gold-bearing vein techniques of the Sturgeon River Mine space. Reference can also be made to the Company’s press releases dated September 5, 2025, Could 27, 2025 and Could 8, 2025.

The reported drill holes beneath, LME25-063, LME25-064, LME25-065 and LME25-066, complete 1,806 m. The holes had been designed to guage the northeast extension of the mineralized system on the historic Brenbar Mine, with gap LME25-063, after which stepping out to the northeast of the Brenbar historic mine shaft concentrating on the untested M50 Quartz vein collection with additional drill holes.

Highlights of Drill Holes LME25-063, LME25-065 and LME25-066

• LME25-063        0.7 m @ 2.67 g/t Au from 139.50 m to 140.20 m;

• LME25-063        0.5 m @ 1.26 g/t Au from 393.40 m to 393.90 m;

• LME25-065        0.50 m @ 1.78 g/t Au from 91.10 m to 91.60 m;

• LME25-065        1.80 m @ 0.95 g/t Au from 149.60 m to 151.40 m, together with: 0.80 m @ 1.90 g/t Au from 150.60 m to 151.40 m;

• LME25-065        0.50 m @ 1.32 g/t Au from 292,30 m to 292.80 m;

• LME25-066        1.50 m @ 1.02 g/t Au from 272,50 m to 274.00 m; and

• LME25-066        0.70 m @ 2.42 g/t Au and 1.90 Au/t from 389.0 m to 389.70 m.

” Whereas these outcomes signify the early levels of testing in a geologically complicated hall, their significance lies in extending our data of mineralization continuity between the historic Brenbar and Sturgeon River Mine areas, ” acknowledged Cynthia Le Sueur-Aquin, President and CEO of LAURION. “That is the primary time drilling has been accomplished throughout this untested structural hall, and it’s yielding precious geological perception with oriented core, that can information the subsequent section of our exploration program. Our focus stays on defining the broader mineralized system that hyperlinks a number of historic mine zones, in the end positioning Ishkōday as a district-scale gold and base steel alternative.”

Notice: (Intervals signify core size. The interval widths reported are down-hole widths. The true widths of the mineralized zones should not identified at the moment as there’s inadequate info to find out the orientation of the mineralization. True widths are estimated at ~70–90% of reported intervals.)

Sampling and QA/QC Protocols

All drill core is transported and saved contained in the core facility positioned on the Ishkõday Challenge in Greenstone, Ontario. LAURION employs an business commonplace system of exterior requirements, blanks and duplicates for all of its sampling, along with the QA/QC protocol employed by the laboratory. After logging, core samples had been recognized after which reduce in half alongside core axis in the identical constructing after which zip tied individually in plastic pattern luggage with a bar code. Roughly 5 – 6 of those particular person luggage had been then stacked right into a “rice” white materials bag and saved on a skid for last cargo to the laboratory.

All core samples had been shipped to the ALS facility in Thunder Bay, Ontario, which had been then ready by ALS World Geochemistry in Thunder Bay and analyzed by ALS World Analytical Lab in North Vancouver, British Columbia. Samples are processed by 4-acid digestion and analyzed by hearth assay on 50 g pulps and ICP-AES (InductivelyCoupledPlasma – AtomicElement-Spectroscopy). Over restrict analyses are reprocessed with gravimetric end.

A complete of 5% blanks and 5% commonplace are inserted randomly inside all samples. 5% of the very best assay end result pulps had been despatched for re-assays. All QAQC had been verified, and no contamination or bias have been noticed. The remaining half of the core, in addition to the unsampled core, is saved in non permanent core racks on the core logging facility in Beardmore and moved to the core storage facility on the Ishkõday Challenge.
