Laurion Nears Completion of Stage 2 Exploration of Mechanized Outcrop

Stripping in Key Gold Bearing Areas at the Ishkoday Gold Project

THIS NEWS RELEASE IS INTENDED FOR DISTRIBUTION IN CANADA ONLY AND IS NOT INTENDED FOR

DISTRIBUTION TO UNITED STATES NEWSWIRE SERVICES OR DISSEMINATION IN THE UNITED STATES.

TORONTO, ONTARIO (September 25, 2018) - Laurion Mineral Exploration Inc. (TSX.V: LME) and

(OTCPINK: LMEFF) (“Laurion” or the “Corporation”) is pleased to update shareholders and

stakeholders on the advancement of the Stage 2 Exploration Campaign (the “ Campaign”) on

the Corporation’s 47 km2 Ishkoday Gold Project (“Ishkoday”).

Laurion’s 18-month exploration program, initiate d in May 2018 has the strategic objective of

outlining the bulk precious and base metals upside potential at Ishkoday. The Campaign follows

a successful Stage 1 field validation work that not only validated precious and base metal results

from a number of selective historic mineralized veins, but also produced significant selective

grab sample assay results in new areas.

The Campaign is centered on mechanized stripping, channel sampling and assaying along

several strategic NW-SE 400m to 500m outcrop stripping lines (the “ Lines”) as a first pass

assessment of the bulk polymetallic veins in the 3km by 1km Target Area. Two lines were

completed (T18-1 and 2; see Figure 1 Location Map. Trees were cut followed by the mechanized

shovel removal of overburden; outcrop cleaning using high pressure water; water recovery in

pits and re-use for outcrop washing; channeling at 0.2m to 1.5m intervals using a gas-powered

saw; sampling, bagging and tagging by field technicians using ALS Laboratory tags, and

geological mapping of the main rock types, structures and mineralization. The field work is being

done by qualified geologists and technicians fr om the exploration service provider Explo-Logik

Inc.

Geological and mineralization highlights from the mechanized stripping:

(1) Line T18-1

Located approximately 1km NE of the part producing Sturgeon Lake Mine’s No. 3 Quartz Vein,

Line T18-1 extends 500m in a NW-SE direction ( Figure 1 ) at right angle to the orientation of

geological units. Bedrock outcrop coverage is approximately 60%. The geology consists of felsic

to intermediate volcanic and intrusive rocks (mostly rhyolite/dacite flows, Tuff and mafic dykes).

Sulphide mineralization (pyrite, chalcopyrite and sphalerite) is rare but increases in narrow NE-

SW trending centimetric and metric shear zones, in addition to sulphide–rich metric-sized veins

similar to those located 700m NE in the “CRK” veins sector. Laurion’s previous channel sampling

work in 2014 from the “CRK” Showing, yielded typical assay results of 8m width of 1.08 g/t gold,

4.90 g/t silver, 1.11% zinc and 0.08% copper, including 5m width of 1.68 g/t gold, 7.00 g/t silver,

1.27% zinc and 0.10% copper.

The northernmost 140m of Line T18-1 depicts 8 NE-SW trending quartz veins belonging to either

the “85-A2” or the “A” vein systems. Both vein systems were historically channel sampled and

assayed by Phoenix Gold (1988) and a selected number of assay results are shown in Figure 2.

Selected historic gold assay intervals of the “85-A2” Quartz Vein system ( Phoenix Gold, 1988 )

from Line T18-1 include 13.41 g/t gold over a 168m length and 19 cm width, including 21.92 g/t

gold over a 52m length and 14 cm width and 14.71 g/t gold over a 50m length and 23cm width;

as well as 20.26 g/t gold (with visible gold or “VG”) over a 20m length and 20cm width from the

Glory Hole Quartz Vein. The quartz veins undulate and form anastomosing patterns as observed

in the “85-A2” vein system, similar to other structurally hosted lode gold deposits.

Selected historic gold assay intervals of the “A” Quartz Vein system ( Phoenix Gold, 1988 ) from

Line T18-1 include 14.71 g/t gold over a 50m leng th and 23cm width (“A-2” Quartz Vein); 0.61

g/t gold over a 25m length and 16cm width (“A-15” Quartz Vein); and 2.31 g/t gold over a 14m

length and 24cm width.

Figures 2 and 3 also show the Stage 1 stripped area located a few meters SW of the main “85-

A2” Quartz Vein outcrop. Here, current channel sampling confirmed the gold-bearing potential

of the 85-A2 Quartz Vein with a selected assay result of 18.50 g/t gold over a 20cm width (Figure

3). A Laurion (2012) selective grab sample yielded 2.86 g/t on an adjacent subsidiary quartz vein

(Figure 3).

As more historic and new quartz vein systems are exposed over the next 12 months, it will be

interesting to observe if the anastomosing patterns will repeat themselves on- and across-strike

giving them bulk length and width potential. The more gold carrying veins the better the

potential. The sulphide mineralization in polym etallic veins, shear zones and as disseminations

could definitely add to this potential.

A total of 472 channel samples were taken from Line T18-1 with precious and base metal assays

as whole rock geochemistry results pending.

(2) Line T18-2

Located approximately 350m W-SW of the part producing Sturgeon Lake Mine’s No. 3 Quartz

Vein, Line T18-2 extends 500m in a NW-SE direction at right angle to the orientation of geological

units (Figure 1). Bedrock outcrop coverage is approximately 80%. The geology consists of felsic

to intermediate volcanic rocks (fine to coarse tuffs, rhyolite/dacite flows, and several

generations of crosscutting mafic dykes). Sulphide mineralization (pyrite, chalcopyrite and

sphalerite) is rare but increases in narrow NE-SW and N trending shear zones.

The southernmost third of the stripped line shows an increase in shearing, brittle deformation and

quartz veining and sulphide development, within generally more siliceous host rocks (principally

rhyolites) offering a significant positive topographic relief. Two major vein sets were identified

Page | 3 

including the newly discovered 040° Bootleg Quartz Vein (the “Bootleg”) that may be the SW

extension of the “85-A2” Quartz Vein located more than 1km to the NE. Significant shearing of

the host rock has produced a quartz-chlorite- sericite-carbonate schist, more than 50m wide,

bearing minor pyrite and numerous centimetric NE-SW trending quartz and quartz-iron

carbonate veins, located 70m SE of the Bootleg.

A total of 475 channel samples were taken from Line T18-2 with precious and base metal assays

as whole rock geochemistry results pending.

A third 500m long NW-SE line was stripped only, T18-3 located 1km SW of the Marge –“F” Quartz

Veins, but without further cleaning nor sampli ng until next season due to wintry weather

conditions. Here, the work has likely uncovered what appears has the extension of the historical

Marge - “F” Quartz Vein system (17.62 g/t gold over a 314m length and 36cm width ( See News

Release October 14, 2008 ), as well as 30.72 g/t gold over a 21m length and a 25cm width;

Phoenix Gold, 1988) some 1km SW of the last known outcrop of the historical vein.

The overall plan of the mechanized stripping, channel sampling and assaying remains to

determine if most or a selective portion of the hundreds of quartz veins identified by previous

workers, and subsequently by Laurion, carry gold, and if the gold mineralization is restricted to

specific areas, whether in higher level intrusives , such as the feldspar porphyry of the Sturgeon

River Mine, and/or polymetallic veins and/or structurally more deformed corridors, such as in

quartz-sericite schists as identified in several outcrops of the Target Area.

As reported in an earlier news release ( see the Corporation’s news release dated August 14,

2018). Of the 322 selective field grab and channel samples taken, 45 samples were anomalous

in either gold, silver, copper or zinc or any combination of these elements. The majority of

samples were taken in the southern claims 3km by 1km Target Area. The southern Ishkoday

claims lies south of the Namewaminikan River, which is considered a key structure or fault

separating the northern and southern claims and geological domains:

 33 assay results were >0.30 g/t gold and 6 assay results were >18 g/t gold - all in quartz

veins with the highest values located in channel samples with Visible Gold from the “85-

A2” Quartz Vein yielding 40.80, 43.00 and 1,185.00 g/t gold ( Figure 1 ). However, two

selective grab samples were not. One is loca ted in a chlorite-sericite schist with trace

pyrite yielding 27.50 g/t gold; and a second, in a porphyry with 1% pyrite gave 28.40 g/t

gold.

 10 assay results >12 g/t silver and 4 assay results >34.28 g/t (1 oz/ton) silver. Half the

anomalous silver results were found in serici te-chlorite-sulphide schists (up to 30.20 and

47.10 g/t silver); the other half in quartz veins (up to 86.40 and 112.00 g/t gold).

 13 assay results >1% zinc. Anomalous zinc is found in four rock settings:

rhyolites/dacites/rhyodacites (up to 1.74% zinc), sericite-chlorite schists (up to 3.26% and

12.00% zinc), chlorite veins (1.89% zinc) and quartz veins (up to 2.82% zinc).

These selected samples may not necessarily be representative of the mineralization hosted on

Ishkoday. Field observations to date, based on the work in the 3km by 1km SE portion of

Ishkoday, (the Target Area), indicates a NE-SW trending extensive, and likely anastomosing

quartz and polymetallic vein system hosting the precious and base metals mineralization. Further

exploration field work is required to confirm the lateral and cross-strike continuity of the

mineralization, and to determine if a bulk tonnage resources model still makes sense. Once

confirmed and a geology-mineralization model is built in 2D, Laurion would initiate diamond

drilling to prove the model in 3-D as part of the Stage 3 program.

Quality Assurance and Quality Control

A total of 1,269 field samples were taken from the Stage 1 and 2 field exploration programs at

the Ishkoday in 2018. All samples including standards, blanks and duplicates were sent to ALS

laboratory facilities in Thunder Bay (Ontario) an d Val-d’Or (Quebec) for analytical preparation

and eventually to Vancouver (B.C.) precious and base metal assays, and whole rock analysis.

Some 322 field samples were taken during Stage 1: 82 channel samples from the Jack quartz-

sericite-chlorite-sulphide schists and the “85-A2” quartz vein, and 240 selective grab samples

from the quartz veins of the northern claims and both quartz and polymetallic veins from the

southern claim blocks. A total of 472 channel samples were taken during Stage 2 from Line T18-

1 and 475 taken from Line T18-2. Each channel sample were saw cut individually by a technician

to lengths chosen by the senior geologists, ranging from 20cm to 1.5m, 5 to 7 cm widths and 7

to 10cm depths. Individual sample weights ranged from 5 to 10kg for channel samples and 1 to

3kg for selective grab samples.

Individual field samples were taken by either field technicians, prospectors or geologists, and

inserted in individual plastic bags, each with ALS sample tags. Samples were checked,

catalogued and bags sealed by the senio r geol ogist, then placed in large numbered nylon

bags with standards, blanks and duplicates. Th e bags were then sealed and transported by

Explo-Logik employees to the ALS facilities. Once at the ALS facilities, samples were catalogued

using the bar coding system, dried, weighed, crushed, pulverized to 70% <2mm, and riffle-split

for final pulverization to 85% <75µm. A final split is taken for multi-element ICP-AES analysis (gold

plus 33 elements) and ore grade finish on anomalous results in gold, silver, copper and zinc.
