LAURION Mineral Exploration Inc. (TSX-V: LME) (OTCPINK: LMEFF) is pleased to report assay results for the first four drill holes of the ten hole, 2,962 m Phase 2 drill campaign, completed on the CRK Zone, Ishkoday Project. Assay results are pending on the remaining six holes. The Ishkoday Project is located approximately 220 km northeast of Thunder Bay, Ontario, near the town of Beardmore in the Onaman-Tashota gold belt.
David Lewis, P.Geo., LAURION Exploration Manager, commented: “Mineralization has been intersected in each of the first four holes, showing good continuity of surficial mineralization to depth. These first four drillholes targeted specific mineralization at the main CRK zone, including the Azurite, A5, Akhi and Joe veins, in areas with poor outcrop exposure.
Thus far, hole LME20-025, targeting the north-striking Joe structure, is our best result at 10.98 g/t gold over 14.25 m (2.42 g/t gold if capped to 30 g/t). On surface, channel sampling returned 4.25 m at 5.98 g/t gold and 2.84 % zinc (see October 13, 2020 news release). Now we are intersecting better gold grades, and across a much wider interval, at 140 m depth. Although there is clearly a variation in gold values across the structure, the increase in mineralized width with depth is very encouraging.”
Cynthia Le Sueur-Aquin, President and CEO, commented: “These are the initiatory drill holes, testing a number of extensional zones to the north of the approximate 680 m by 380 m wide CRK Zone. The drill holes target these extensional zones where channel sampling returned very encouraging results, but where exposure was minimal.”
Significant assay data is presented in Table 1 and drill hole position and orientation data is presented in Table 2. A plan map of mineralization and drill sections are presented in Figure 1.

The CRK Zone, which was trenched and exposed in 2019, two distinct styles of mineralization: an early, likely syn-volcanic, zinc-dominant hydrothermal system, termed the Ishkoday-style mineralization; and a later, gold-dominant event that is linked primarily to later tectonic gold-silver bearing quartz veins, termed the Sturgeon River-style mineralization. Magnetite is associated with the higher-grade zinc mineralized zones.
Surficial mapping and channel sampling of the trenched CRK outcrop documented two orientations of Ishkoday-style mineralization including N- and NE-striking. Sturgeon River-style veins and shear zones cut these early structures and remobilize and enrich the early Ishkoday-style mineralization.
These two mineralizing systems have been intersected in drill core and were oriented using Boart/LongyearTM TruCoreTM. The orientation of structures, including veins and shear zones, was validated with the relative position on drill core of a lower reference line, measured using alpha and beta (α / ß) angles, and converted into strike and dip measurements. These measurements, in conjunction with surficial measurements, were used to plot structures in sections and in 3D.
Reclassification of the Joe and Akhi structures
Ishkoday-style mineralization is generally defined as early (synvolcanic) polymetallic veins associated with actinolite and magnetite, whereas Sturgeon River style veins are late gold and silver-bearing quartz veins and shear zones that cut the earlier mineralization. On surface, the north-trending Joe and northeast-trending Akhi veins host gold, silver, copper and zinc (Figure 1). At depth in hole LME20-025, gold and zinc mineralization in the Joe vein do not occur together and gold mineralization occurs in a shear zone. Along trend of the Akhi vein to the northeast, the style of mineralization changes from sheared actinolite/magnetite to a rotated and shear-hosted quartz vein at the Sturgeon granitoid contact. In both cases, these mineralized structures, although likely initially formed as Ishkoday-style, synvolcanic, polymetallic veins, are reclassified as shear zones.
This distinction is important for the following reasons:

Channel samples are individually cut, perpendicular to mineralization, using a double-bladed saw to specific lengths. Samples are cut to approximately 5 cm width and 10 cm depth, with individual samples weighing approximately 1.5 to 4 kg. Channel samples are inserted into individual plastic bags, labelled and containing unique sample tags, and sealed. Aluminum tags with the sample tag information are inserted at the beginning of each channel sample cut. Collected field data includes sample number, channel azimuth, sample length, rock type and GPS UTM coordinates. Samples are catalogued and industry-standard Quality Assurance/Quality Control samples are added, including standards, duplicates and blanks, in a pre-established order. Samples are then sealed in nylon bags and shipped by LAURION personnel to the ALS facility in Thunder Bay, Ontario.
All core and channel samples have been assayed by ALS Laboratories in Thunder Bay, Ontario. Samples are processed by 4-acid digestion and analyzed by fire assay on 50 g pulps and ICP-AES (Inductively-Coupled-Plasma – Atomic-Element-Spectroscopy). Over limit analyses are reprocessed with gravimetric finish.
About LAURION Mineral Exploration Inc.
The Corporation is a junior mineral exploration and development company listed on the TSX-V and on the OTCPINK. The Corporation currently has 198,718,522 outstanding shares, of which approximately 71% of LAURION’s issued and outstanding shares are owned and controlled by Insiders who are eligible investors under the “Friends and Family” categories.
LAURION’s emphasis is on the development of its flagship project, the 100% owned mid-stage 47 km2 Ishkoday Project, and its gold-silver and gold-rich polymetallic mineralization with a significant upside potential. The mineralization on Ishkoday 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, in the past producing Sturgeon River Mine. The recently acquired Brenbar Property, which is contiguous with the Ishkoday Property, hosts the historic Brenbar Mine and LAURION believes that the mineralization to be a direct extension of mineralization from the Ishkoday Property.
