LAURION Reports High-Grade Gold-Copper Grab Samples up to

26.0 g/t Au and 1.61% Cu from Historic Miron Zone, Ishkōday

Project

TORONTO, Ontario — July 10, 2026 — LAURION Mineral Exploration Inc. (TSX-V: LME | OTCQB:

LMEFF | FSE: 5YD) ("LAURION" or the "Company") is pleased to report results from a program of

grab sampling completed at the historic Miron Zone, located on the Company's 100%-owned

Ishkōday Gold & Polymetallic Project in the Beardmore -Geraldton Greenstone Belt,

Northwestern Ontario.

Highlights

● A total of 15 grab surface rock geochem samples were collected from the Miron Zone

quartz vein exposure, following excavation, dewatering, and clean-up of a historic test

pit that had been overgrown and water-filled.

● Assay results include a high -grade sample of 26.0 g/t Au and 1.505% Cu (sample

S358072), and a second sample returning 8.82 g/t Au and 1.61% Cu (sample S358073).

● A third sample returned 0.881 g/t Au with 1.485% Cu (sample S358076), reinforcing a

consistent gold-copper association at this showing.

● Results confirm the polymetallic character of the Miron Zone, consistent with the

Company's broader interpretation of the Ishkōday corridor as an orogenic gold system

overprinting an earlier base-metal mineralising event.

● The Miron Zone was previously tested by three historic diamond drill holes in 1987– 88

(Farboro Resources Inc. and Oz Exploration Inc., 1988 — see "Miron Zone Background"

below for full source citation). None of the three holes returned gold grades

comparable to historic surface sampling of the vein; results indicate the vein widens to

the southwest, a trend that has not been tested at depth. The Company's 2026

exploration program is designed to test the southwest widening trend.

representative of the mineralization hosted on the property. The 15 samples ranged from

<0.001 g/t Au and 0.0004% Cu to 26.0 g/t Au and 1.61% Cu. A nomalous results are reported

above.

Miron Zone Background

The Miron Zone (Miron Vein) is located north of Coyle Lake within a single 6.0 km by 2.5 km

mineralised corridor of the Ishkōday Project. The zone is characterized by a quartz vein

approximately 2.1 metres wide, striking approximately 022° with a near-vertical dip, historically

exposed by a 10.6- metre test pit. The Miron Zone grab sample locations are centred at

approximately 447195.9 E, 5513888.8 N (NAD83 UTM Zone 16N).

The vein was previously tested by three diamond drill holes, drilled at the same azimuth and

dip from collars spaced 25 metres apart along strike, totalling 183.18 metres. None of the three

holes returned gold grades comparable to the historic surface sample grade from the same

vein: the hole drilled beneath the historic test pit returned a best value of 200 ppb Au; the hole

drilled 25 metres to the northeast returned no significant values; and the hole drilled 25 metres

to the southwest intersected a wider zone of quartz veining (5.61 metres) but only anomalous

gold values up to 280 ppb Au. (Farboro Resources Inc. and Oz Exploration Inc., Report on

Winter 1987-88 Exploration Program, Project 474 – Sturgeon River, Elmhirst Township, Ontario,

NTS 42E/13 , authored by Robert J. Tremblay, Senior Geologist, D.I.G. Mining Enterprises Inc.

(Project Manager), dated June 1988 .) While drill-tested gold grades to date have remained

low, the most southwestern hole indicates the vein widens in that direction – a trend that the

Company believes warrants further testing at depth.

The historic pit had become overgrown with trees and shrubs and was water-filled at the time

LAURION's field crew, led by prospector, Rick Cote, undertook excavation, dewatering, and

site clean-up. This work re-exposed the vein and enabled the collection o f the grab samples

reported here.

The Company's 2026 exploration program will potentially include two (2) diamond drill holes

designed to test the down-plunge extension and southwest widening of the vein indicated by

the 1987–88 drill fence, with oriented core planned to confirm plunge direction ahead of the

full program.

Sample Method and QA/QC

Samples were collected as grab samples by Company personnel and delivered under chain

of custody to ALS Canada Ltd. (" ALS"), an accredited, ISO/IEC 17025- certified laboratory.

Sample preparation was completed at ALS's facility in Thunder Bay, Ontario (fine crushing to

70% passing 2 mm, riffle split, pulverization of 250 g to 85% passing 75 microns), with analysis

completed at ALS's facility in North Vancouver, British Columbia. Gold was analyzed by 50 g

fire assay with an atomic absorption or gravimetric finish (Au-GRA22 gravimetric finish applied

to samples returning greater than 10 g/t on the initial screen); a 34- element ICP-AES/ICP-MS

multi-element package was also completed, with copper values exceeding the upper limit of

that method re-assayed using an ore-grade four-acid ICP-AES method.

Grab samples are a selective, judgmental sampling method used to characterize

mineralization at a showing or outcrop and are not necessarily representative of the

mineralization hosted on the property as a whole. The Company did not insert additional blind

field standards into this sample batch. ALS's own internal laboratory QA/QC program, including

certified reference materials, blanks, and duplicate analyses, was applied to this sample batch

as part of the laboratory's routine internal quality control process.
