Toronto, Ontario – December 3, 2025 – LAURION Mineral Exploration Inc. (TSX.V: LME |
OTC: LMEFF | FSE: 5YD) (“LAURION” or the “Corporation”) is pleased to announce assay
results from four diamond drill holes ( LME25-067 to LME25-070) completed as part of the
Corporation’s 2025 exploration drilling program at the 100% -owned Ishkōday Project
located near Greenstone, Ontario. These results continue to confirm the presence of
stacked, high-grade orogenic gold veins within the emerging Marge –Allard multi-vein
corridor, northeast of the M21–M24–M25 trenching and Sturgeon River Mine.
The 2025 drill program , which was originally announced by the Corporation on May 8,
2025, comprised 15 drill holes totaling 7,586 metres , bringing cumulative drilling at
Ishkōday to 99,834 metres in 470 drill holes. Assay results for the 11 other holes completed
pursuant to the drill program were previously announced on August 19, 2025, September
23, 2025, November 4, 2025 and November 25, 2025. This press release reports the final
1,716 metres of 2025 drilling (holes LME25-067 through LME25-070), completing disclosures
for the year’s program in the Sturgeon River-Brenbar corridor.
The results from these four (4) drill holes comprise the highest grade intercepts for this
season together with strong continuity of near surface veins. These results collectively
demonstrate consistent high-grade mineralization across multiple stacked gold-bearing
structures, confirming the robustness of the Marge–Allard corridor.

GEOLOGICAL CONTEXT AND SIGNIFICANCE
The four holes reported today targeted the eastern extension of the Marge– Allard vein
system, a multi -vein domain situated approximately 700 metres north of the historic
Sturgeon River Mine. The area hosts a network of gold-bearing quartz veins including:
• Marge Vein and Marge vein sets (MPA, MPB, MPG)
• Allard Vein
• F and X veins
• 85-3, 85-3C, and M58 veins
Regarding historical work:
• Phoenix Gold Mines (1984) channel sampled the Marge Vein over 154 metres strike
length with subsequent trenching and mapping exten ding the vein to 297 metres
in strike length. Furthermore, several nearby veins (F, X, Allard) also yielding visible
gold and high-grade assays. (L.O. Koskitalo – Phoenix Gold Mine Project Geologist
– 1988.)
• LAURION’s own stripping and channel sampling in 2008 returned 16.97 g/t Au over
0.47 m across 47 metres of exposed Marge Vein strike length. (Report on Grab
Sampling and Diamond Drilling programs – 2015 – Dr. Neil Westoll.)
The 2025 drilling results reinforce the interpretation of this area as a multi-vein, structurally
controlled gold system with potential for plunging high-grade shoots extending down-dip
and along strike. In particular, drill holes LME25-067 and LME25-069 demonstrate that high-
grade mineralization persists both near surface and at significant depths (to >700 m), with
vein stacking providing cumulative gold potential.
"With the 2025 drill program now fully reported, LAURION will integrate the new data into
its 3D geological and structural model for Ishkōday. LAURION will continue its focus on the
Sturgeon River–Brenbar Corridor as well as the A -Zone-CRK corridor in line with its 2026 –
2027 Strategic Operating Plan. Work will include structural consolidation and 3D
modelling, followed by plunge-oriented drilling to evaluate continuity of high-grade D2-
controlled shoots identified in our drill programs. This program will refine high -priority drill
targets and advance structural understanding across the Ishkōday Project,” stated
Cynthia Le Sueur-Aquin, President and CEO of LAURION.

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 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 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 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 Ishkõday Project.
