LAURION ANNOUNCES COMMENCEMENT OF FIEL D WORK TO VALIDATE EXISTENCE OF A

LARGE NEAR-SURFACE GOLD-POLYMETALLIC TARGET ON THE ISHKODAY PROJECT

NOT FOR DISTRIBUTION TO UNITED STATES NEWS SERVICES OR DISSEMINATION.

INTENDED FOR DISTRIBUTION TO UNITED STATES NEWSWIRE SERVICES OR DISSEMINATION

IN THE UNITED STATES.

TORONTO, ONTARIO - (May 29, 2018) – Laurio n Mineral Exploration Inc. (TSX.V: LME and

OTCPINK: LMEFF) (“Laurion” or the “Corporation”) is pleased to announce the start of

the summer field program at the Corporation’s 47 km 2 Ishkoday Project (“Ishkoday”).

Laurion’s personnel and Explo-Logik’s technical crews (the “Team”) have already

mobilized to site.

The Corporation’s overall objective is to validate the existence of a large (bulk) near

surface /gold-polymetallic target (the “Targe t”) over the identified 3 km by 1 km main

outcrop area, containing all of the known precious and base metals mineralization

known to date, in an expedited fashion in order to move the project to the next

development phase.

The Corporation has designed a strategic three-phased exploration program over the

next thirty-six months, which aims at the Ta rget validation and concentrating on rapidly

defining and expanding via drilling near surf ace mineral resources in gold, silver, zinc

and copper.

The Laurion Private Placement tranches planned in 2018 will permit the execution of:

(i) GIS compilation, synthesis and interpretation of the project’s technical data,

producing a 3-D view of the geology and mineralization, and targeted

upside potential;

(ii) An initial field validation exploration program that may consists of airborne

and/or ground geophysical surveys covering the 47 km 2 Ishkoday to better

define the geological and structural elements of the entire project; and

(iii) Followed by geological mapping of key areas, including a continuous

surface stripping, channel sampling and assaying of potential zones, to

outline the Target.

The known mineralization on Ishkoday exhibits repetitive stacked and multi-directional

gold and zinc-rich sulphides in lenses, veins and vein stockworks, visible in the

mineralized outcrop exposure. The northerly trending vein sets are gold-silver-quartz

bearing; whereas the NE sets are gold-silver-zinc-copper bearing.

The abundance and proximity of these vein sets within a 3 km by 1 km outcrop segment

of Ishkoday, highlights the possibility for the Target potential, at the same time offering a

Volcanogenic Massive Sulphide (or “VMS”) metallogenic environment, as well as

individual higher gold grade veins that could potentially be developed separately.

To date, the Corporation has a property-wide database of 283 diamond drill holes

totaling 40,729 m, detailed sampling, mapping, assays and geochemical analysis, and

ground geophysics. The mineralization is open at depth beyond the current core

drilling limit of -200 m from surface, based on the historical mining to a -685 m depth, as

evidenced in the past producing Sturgeon River Mine (the “Mine”). The Mine produced

73,322 ounces of gold, and 15,929 ounces of silver from 1936 to1942 on the No. 3 Vein at

24 g/t gold, and generated a large gold and silver bearing stockpile of 144,070 tonnes

grading 1.59 g/t gold in the Indicated Mineral Resources category (based on a NI 43 -

101 Technical Report filed on SEDAR in June 2013 – See Press Release dated April 23,

2013).

Initial Highlights of the 2018 Campaign

The GIS compilation work is advancing as pla nned with more than half of the technical

data already compiled, and is expected to be completed by mid-June. The Team’s

initial field evaluation of the previous exploration work, geology and mineralization is

also proceeding diligently to validate the Target. Latest highlights include:

 Ishkoday hosts structurally-hosted gold-base metal mineralization in centimetric to

metric wide shear and tension “veins” extending tens, hundreds and several

thousand metres in length in a NE-SW structural trend visually defined over a

minimum 3km by 1km area (3 km 2), but likely extend N-S outside the 1 km wide

known vein field onto the northern claims held by the Corporation.

 For now, the distribution of the mineralized trends appear to follow axes from a NE-

SW Strain Ellipse in a Simple Shear Deformation Model with the axes depicting the

crisscrossing shears containing the known mineralized “veins” at Ishkoday, whether

sulphide-gold-rich and/or gold-rich – the sulphide-gold-rich. All of the veins appear

to have been emplaced during regional deformation of the belt.

 The presence of abundant sulphides co ntaining zinc (sphalerite) and copper

(chalcopyrite) in a number of veins from areas of pyroclastic breccias

(“agglomerates”) could potentially indicate the presence of sulphide lenses in

proximity.

 Drilling since the 1980’s shows the Target po tential at Ishkoday – there are 85 assay

interval results over 5 g/t gold with silver, copper and zinc credits from 0.1m to 3.2m

interval lengths within the known 3 km2 mineralized trend.

 Ishkoday has hundreds of veins, as atte sted by detailed mapping from previous

operators in the 1980’s and Laurion’s exploration work from 2010 to 2014.

Current observations strongly suggest major “vein stockworks”, as can be observed

at the Dome, Canadian-Malartic, Detour and Sigma-Lamaque Deposits from the

Abitibi Greenstone Belt. Contrary to these other deposits, Ishkoday shows two

mineralized systems, one gold-silver-rich and the other gold-silver-zinc-copper.

The Next Exploration Steps

Laurion has commenced the field work to validate the Target based on priority areas:

(1) Sturgeon River Gold Mine - Historic Mine Site

Laurion’s main project mandate is to complete the relevant economic studies for the

potential processing of the surface stockpile . Processing of the surface stockpile will

facilitate the mineral characterization representative of the host rock mineralized

trends, simultaneous with evaluation and development of the “proximal mine” gold

mineralization within 1 km of the stockpiles, which could potentially generate feed for

future operations.

Initial work will consist of relogging of drill core, and stripping-sampling existing (and

new) gold bearing veins to outline wide gold bearing stockworks.

(2) Gold vein extensions (outward from the historic mine site)

The second priority is to expand the identifi cation and evaluation of gold bearing veins

on strike of the vein sets identified at the mine site. This task is also intended to identify

and outline gold bearing vein sets and stockworks.

(3) Polymetallic mineralization (gold-silver-copper-zinc)

Ishkoday contains interesting polymetallic mineralization that occurs in outcrop and

also in drill core. Although somewhat early in its understanding, it is not clear if the

observed mineralization is an indication of a Volcanogenic Massive Sulphides or VMS or

if it indicates a more extensive polymetallic-gold system that may be related to the

gold mineralization.

Relogging of existing core, prospecting and st ripping-sampling will be used to increase

understanding of the geology, determine extent and origin of, and size potential of the

gold-silver-copper-zinc.

(4) Regional prospecting (Ishkoday north claims area)

Claims located in the northern part of Ishkod ay will be prospected to identify favorable

areas for gold and polymetallic-gold mineralization for near-term follow up exploration.
