Laurion Provides Updates on Selective Grab Assay Results and Initiates Stage 2 Exploration of Mechanized Outcrop Stripping in Key Gold Bearing Areas at the Ishkoday Gold Project

Toronto, CANADA


TORONTO, Aug. 21, 2018 (GLOBE NEWSWIRE) -- Laurion Mineral Exploration Inc. (TSX.V: LME) and (OTCPINK: LMEFF) (“Laurion” or the “Corporation”) is pleased to announce the commencement of the Stage 2 Exploration Campaign (the “Campaign”) on the Corporation’s 47 km2 Ishkoday Project (“Ishkoday”). Laurion’s new 18-month exploration program initiated in May 2018 has the strategic objective of outlining the bulk precious and base metals upside potential at Ishkoday. The initial Stage 1 field validation work which commenced in May, focused on prospecting, geological mapping and sampling with manual stripping and channel sampling of selective historic mineralized veins and in new areas.

Update of Selective Grab Assay Results

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:

  • Northern Ishkoday Claims :
    • 150 grab samples were taken from the northern claims; and,
    • Only 5 anomalous gold assay results: 3 grab samples between 0.1-1 g/t gold, 1 between 1-5 g/t gold and 1 above 5 g/t gold;
  • Southern Ishkoday Claims – 3km by 1km Target Area:
    • 172 combined grabs and channel samples - 90 grabs and 82 channels - were taken from the southern 3km by 1km Target Area;
    • 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 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).

These selected samples may not necessarily be representative of the mineralization hosted on Ishkoday. Additional multi-element geochemical results with correlation factors and more location maps, including the detailed channel sampling maps of the 85-A2 gold bearing quartz vein sector (the “85-A2”) will be made available in the coming weeks as Laurion progresses in its work.

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 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.

The Stage 2 Exploration Work

The Stage 2 exploration 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 polymetallic veins in the Target Area. 

The first of several Lines will pass just east of the 85-A2 as it the potential of extending a number of the higher gold grade grab and channel samples 100m on strike, as well as testing a number of previously unexplored sulphide-rich veins located 700m SW of 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.

It will be essential 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 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.

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

A total of 322 field samples 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).
