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, Aug. 14, 2018 - Laurion Mineral Exploration Inc. (TSX.V: LME) and (OTCPINK: LMEFF) (“Laurion” or the “Corporation”) is pleased to announce the first precious and base metals assay results from initial May-June 2018 validation program (the “Stage 1 Campaign”) at the Corporation’s 47 km² Ishkoday Project (“Ishkoday”).

The field validation exploration program consisted of geological mapping and prospecting of selective historic mineralized veins and their extensions, and in new areas. New mineralized occurrences were manually stripped, cleaned and mapped. Grab and whenever possible deep channel samples were taken for gold and multi-element analysis.

The appended Table 1 summarizes the most significant selective field grab and channel sample results in Gold (Au), Silver (Ag), Copper (Cu) and Zinc (Zn). Assay results highlights include:

• Of the total samples taken some 14% of the samples (45 of 322 selective field samples) were anomalous in either gold, silver, copper or zinc or any combination of these elements, and most were located in the southern 3km by 1km Target Area (with a few exceptions)(Figure 1);
  
• 33 assay results >0.30 g/t gold and 6 assay results >18 g/t gold. All are in quartz veins with the highest values located in channel samples with Visible Gold from the 85-A2 yielding 40.80, 43.00 and 1,185.00 g/t gold. However, two selective grab samples were not. One is located 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 sericite-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);
  
• 1 assay result >1% copper in a diorite/granodiorite porphyry (1.61% copper); and
  
• 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).

Figure 1 outlines selective assay results >0.3 g/t gold and >1% zinc set on a backdrop of the Phoenix Gold (1988) quartz vein highlighting a selective number of historic channel sampling gold interval and gold-zinc grab samples results, as well as the Kodiak Exploration (2010) VTEM B-Field Z Component Time Gate 6.125ms geophysical survey maps showing one of the significant unexplored NE-SW trending conductors, which is on trend to a number of known zinc-sulphide veins at Ishkoday.

These selective field sample assay results and additional multi-element geochemical results with correlation factors and additional detailed location maps will be made available in the coming weeks as Laurion initiates the second stage work program.

Laurion’s Exploration Campaign

Laurion’s new exploration work with the objective of ascertaining the bulk gold and gold/base metal upside potential at Ishkoday commenced in May of this year - the first of an 18 month three-staged program. 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 and extensive quartz and polymetallic vein system as host to the gold and gold/base metals mineralization. Additional 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.

Field prospecting and mapping identified two multi-kilometric quartz veins systems within the Target Area, the historic “85-A” and “Marge-F” quartz veins sectors (see the Corporation’s news release dated July 31, 2018). Both contain abundant multi-directional and anastomosing quartz veins. The “85-A” Vein sector defines a minimum 1,500m long by 500m wide corridor and contains 56 centimeter to meter wide quartz veins, one of which, the “A-2” Vein is multi-kilometric long. The “85-A2” Vein shows interconnected 045° and 020° oriented quartz veining forming anastomosing stockworks.

In addition to the quartz veins, there are a minimum six polymetallic-sulphide veins of various metric lengths and widths are believed to be centered on “volcanic vents”, associated with mafic/felsic dykes, silicification and quartz veining, granodiorite-diorite porphyries, rhyolite and rhyodacite (brecciated) flows and tuffs, secondary brecciation, chlorite alteration as veins; and sphalerite, chalcopyrite and galena, magnetite, gold and silver

It will be essential to determine if most or a selective portion of the hundreds of quartz veins identified by previous workers, and now by Laurion, carry gold, and if the gold mineralization is restricted to certain areas, whether high level intrusives, such as the 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.

The planned work to be initiated later in Q3-2018, as part of if the Second Stage work, will include mechanized and manual outcrop 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 gold-quartz and gold-polymetallic (copper-zinc) veins in the Target Area.

Quality Assurance and Quality Control (“QA-QC”)

A total of 322 field samples (not 367 as previously stated) were taken from Ishkoday: 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. An additional 26 standards, blanks and duplicates were added for QA-QC, for a total of 348 analyzed samples.

Individual field samples were taken by prospectors and geologists, and inserted in individual plastic bags, each with ALS sample tags. Samples were checked, catalogued and bags sealed by the Senior Project Geologist, then placed in large numbered nylon bags with standards, blanks and duplicates. The bags were then sealed and transported by Explo-Logik employees to the ALS facilities in Val-d’Or for gold and multi-element analysis.

Once at the ALS facilities, samples are catalogued with the bar coding system, dried, weighed, crushed, pulverized to 70% <2mm, and riffle-split sample is taken 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).
