TORONTO, Sept. 12, 2019 -  Laurion Mineral Exploration Inc. (TSX.V: LME) and (OTCPINK: LMEFF) ("LAURION" or the "Corporation") is pleased to provide new gold, silver, zinc and copper assay results from the 2019 field exploration program (the "Stage 2 Campaign") at the Corporation's wholly-owned Ishkoday Project ("Ishkoday") located 220 km northeast of Thunder Bay (Ontario). The Stage 2 Campaign forms part of the 2018-2019 exploration initiated in May 2018 as a three-staged 18-month program with the strategic objective of outlining the precious and base metals upside potential at Ishkoday, part of the now 5 km by 1 km Target Area (the "Target Area") of the southern claims block (refer to the Corporation's 2019 news releases dated June 14, July 17, August 1, August 7 and August 20).

First CRK Assay Results

Selected outcrop stripping and surface channel sampling (refer below to the QAQC Protocols for detailed methodologies) over a 450m long segment of the northeast-southwest Loki Sulphide Veins Trend at the CRK Zone has outlined multiple centimeter to meter wide zinc and copper sulphide veins (sphalerite, chalcopyrite). The first individual channel sample assay results from the multiple sulphide veins and the A-2 Quartz Vein of the 30m by 20m CRK West stripped outcrop #37 are summarized as follows:

LAURION's diamond drill hole LME14-031 (445591E/5512014N, 100°/-50°, 98m) intersected the same sulphide veins sampled at surface at a vertical depth between 30-35m from surface yielding 0.75 to 1m core lengths (70-75% real widths) of 0.09 to 39.50 g/t gold, 0.7 to 14.7 g/t silver, 0.03 to 1.28% zinc and 0.02 to 0.16% copper. Surface channel samples of the A-2 Quartz Vein at this location gave 2.28 g/t gold over 0.3m (Sample 867817), 1.21 g/t gold over 0.21m (Sample 867847), and 1.77 g/t gold over 1.0m (Sample 867880); whereas it yielded 0.20 g/t over 1.2m in LME14-031.

Ishkoday is an outlier of predominantly diorite/granodiorite plutons and dykes that were intersected by stringer and massive sulphide veins containing gold, silver, zinc and copper sulphides. Additional gold-rich lode quartz veins were emplaced cut by chlorite-actinolite-magnetite-sulphide bearing veins/shears. All these vein sets extend 100's to 1,000's of meters in lengths, occurring as multiple individual sinuous and anastomosing centimeter to meter wide veins, and forming corridors several hundred meters in width.

Quartz veins hosts high grade gold grades as was recently reported by LAURION on the No. 3 Quartz Vein South (refer to the Corporation's news release dated August 20, 2019) that included in-vein composite interval assays of 47.61 g/t gold over 7.95m (sample line 5-L26P), 92.58 g/t gold over 12.98m (sample line 5-L27P), 79.64 g/t gold over 4.18m (sample line 5-L28P) and 14.85 g/t gold over 9.45m (sample line 5-L29P).

Stage 2 Campaign Update

Details of the completed stripping, channel sampling and rehabilitation work of the Stage 2 Campaign are compiled in the following table.

The scheduled airborne drone magnetic survey with low altitude photos was completed in August. The survey results along with the drill core re-logging exercise will standardize rock units and their contacts, structures, sulphide-magnetite veins and define litho-structural domains. LAURION is presently focussed on adding to and updating the leading-edge Ishkoday database for geological and eventual mineral resources modelling.

Confirming the extensions of known and new gold bearing quartz and polymetallic sulphide veins is the priority of the Stage 2 Campaign and will ultimately facilitate in completing the construction of the 2-D and 3-D geological-mineralization model (the "Model"). This Model will presents LAURION with a solid technical base to initiate diamond drilling to prove the upside potential as part of the Stage 3 program to commence in Q4-2019-2020. LAURION's work continues to confirm the extensive quartz and sulphide veining across the Target Area. The field portion of the Stage 2 Campaign is slated for completion by the end of Q3-2019.

QAQC Protocols

Assay samples from this program are being processed by ALS Global Geochemistry in Thunder Bay, Ontario, and analyzed by ALS Global Analytical Lab in North Vancouver, BC, using the Fire Assay method of analysis. LAURION employs an industry standard system of external standards, blanks and duplicates for all its sampling in addition to the QA/QC protocol employed by the laboratory.

Each surface outcrop channel sample was individually cut using a double-blade saw by a field technician to lengths chosen by the geologists, to an approximate width of 5cm and 10cm depth. Up to 3 saws were used. Individual channel samples weighed from 5 to 10kg. Each channel was sampled by supervised field technicians, and inserted in individual plastic bags, each with ALS sample tags, then sealed on-site. Metal tags with the ALS sample number were inserted at the beginning of each sample channel cut and are used during the field mapping of individual channel sample cuts. The field data gathered includes sample number, azimuth of channels, sample lengths, geology and geo-reference using UTM coordinates.

Individual plastic sample bags were then catalogued and inserted in large nylon bags along with standards, blanks and duplicates in a pre-established sequence. The nylon bags were then sealed and transported by LAURION technicians to the ALS facility in Thunder Bay, Ontario. Once at ALS, individual 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 50 gram pulp split was taken for Fire Assay using Au-ICP22 gold analysis up to 10,000 ppb gold. Samples giving results beyond 10,000 ppb gold are re-analyzed with a new 50 gram pulp split to ore grade levels using a gravimetric finish. Sulphide vein samples were also analyzed using the ICP61 multi-element analysis.
