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

Turnaround Time for Assay Results
5 | Page
Due to continued high sample volumes across the assay laboratory industry, the Company is currently
experiencing up to a 12-week turnaround time between sample submission and receipt of final assay
results. 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 wit h 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 , L AUR ION is e xe cu t ing a cle ar
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 t he 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.
