LAURION Extends Drilling into Untested Ground Linking
Brenbar and Sturgeon River Mine Corridors at Ishkōday
Toronto, Ontario – November 25, 2025 – LAURION Mineral Exploration Inc. (TSX.V: LME |
OTC: LMEFF) (“LAURION” or the “Corporation”) is pleased to announce encouraging
results from its 7,700- metre Summer 2025 drill exploration program at the 100% -owned
Ishkõday Project, located 220 km northeast of Thunder Bay in Greenstone, Ontario. The
first five drill results were announced in the Corporation’s press releases dated August 19,
2025 and September 23, 2025, respectively, which targeted the high-grade gold-bearing
vein systems of the Sturgeon River Mine area. Reference is also made to the Corporation’s
press releases dated September 5, 2025, May 27, 2025 and May 8, 2025.
The reported drill holes below, LME25 -063, LME25-064, LME25-065 and LME25 -066, total
1,806 m. The holes were designed to evaluate the northeast extension of the mineralized
system at the historic Brenbar Mine, with hole LME25-063, and then stepping out to the
northeast of the Brenbar historic mine shaft targeting the untested M50 Quartz vein series
with further 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, including: 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.
“While these results represent the early stages of testing in a geologically complex
corridor, their significance lies in extending our knowledge of mineralization continuity
between the historic Brenbar and Sturgeon River Mine areas, ” stated Cynthia Le Sueur -
Aquin, President and CEO of LAURION. “This is the first time drilling has been completed
across this untested structural corridor, and it is yielding valuable geological insight with
oriented core, that will guide the next phase of our exploration progr am. Our focus
remains on defining the broader mineralized system that links multiple historic mine zones,
ultimately positioning Ishkōday as a district-scale gold and base metal opportunity.”

Sampling and QA/QC Protocols
All drill core is transported and stored inside the core facility located at the Ishkõday
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 indivi dual 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 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
(InductivelyCoupledPlasma – AtomicElement-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 QAQC 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 Ishkõday Project.
