LAURION Confirms Continuity from A-Zone to McLeod in Undrilled Areas and at Depth Intersecting up to 2.79 g/t Au, 0.34% Cu and 31.66 g/t Ag over 1.6 meters

TORONTO, Aug. 31, 2022 - Laurion Mineral Exploration Inc. (TSX.V: LME) (OTCPINK: LMEFF) ("LAURION" or the "Corporation"), is pleased to announce the assay results for nine (9) new diamond drill holes, totalling 4,207.5m, which tested the potential continuity of mineralization between the southwestern portion of the A-Zone the McLeod Zone.

These results confirm the strike length extension of the A-Zone over 1.6km and remains open close to surface towards the Northeast and at depth towards the Southwest. The drilling also confirmed the continuity of the mineralization between the CRK and McLeod areas, in previously undrilled areas. Both the A-Zone and McLeod Zones are located along the 6 km long Au-Zn-Cu-Ag mineralized trend at the Ishkoday project, near Beardmore, Ontario.

The results for hole LBX22-072 to LBX22-080 (9 holes) include the following intersections.

Drill holes LBX22-072 and 074 tested a potential N-S zone at 300m depth, which was found to hold mineralization. Holes LBX22-073, located to 205 m to the northeast of drill holes LME11-013 (3.22g/t Au, 27.5g/t Ag, 0.38% Cu and 5.63% Zn) in the Ahki Vein area has also confirmed the northeast extension of this system.

Drill holes LBX22-075 and 076 successfully confirmed the southwestern continuity of the McLeod Zone at depth. Drill holes LBX22-077 to 082 also tested the potential extension of the A-Zone mineralization to the southwest between the A-Zone and McLeod Zone, with current results confirming the continuity of the mineralized system.

"The 2022 drill program has demonstrated the continuity of the current mineralized zones in new and undrilled areas, while also identifying new exploration targets in high grade trends," stated Cynthia Le Sueur-Aquin, President and CEO of LAURION. "These results significantly increase the mineral exploration potential of the Ishkoday Au-Zn-Cu-Ag deposit. We are most pleased with the success of the 2022 drilling and mapping programs, which have demonstrated that the stacked vein systems remain open at depth, along strike, and width to both the northwest and southeast, which suggests that the mineral exploration potential of the Ishkoday Au-Zn-Cu-Ag deposit may increase with continued targeted future drilling and exploration programs."

LAURION commenced a diamond drilling program in January 2022, completing 14,211.5 m in 46 drill holes. The last drill hole was completed on July 4, 2022. The Corporation is still awaiting the assay results of 14 drill holes. The 2022 diamond program was designed to test the potential of the undrilled continuity of the mineralization between the A-Zone, McLeod and CRK areas.

The drilling intersected stacked and steeply dipping volcanogenic polymetallic mineralized zones and orogenic gold veins from the A-Zone to the McLeod Zone, situated within a 1.5 km northeastern segment of the 6 km-long Ishkoday mineralized trend

The 2022 drilling expanded the stacked vein system in the A-Zone and McLeod area from an area of 1.1 km by 250 m (in 2021) to 1.5 km by up to 400 m in the A-Zone and up to 600 m in the McLeod Zone. The mineralized trend remains open at depth and on strike. To date, 419 drill holes, for a total of 78,663 m, have been drilled on the Ishkoday.

A hand-stripping, power-washing and channel sampling program in advance of the mapping program is in progress, with the aim of 1) opening up key areas to the west of the McLeod and CRK Zones; and 2) assisting with the critical structural and alteration mapping, which is crucial to enhancing the 3D model and future drill targeting. These key exploration activities will assist the technical team in confirming of the continuity and expansion of the mineralized strike length.

Samples from the 2022 drilling were cut and sent for analysis. Preparation and analysis were completed at the Actlabs (ISO 9001:2015) laboratory in Thunder Bay. Actlabs is an internationally recognized laboratory that provides geochemical sample preparation, analytical procedures, and data management solutions. LAURION uses a quality assurance/quality control (QA/QC) program that monitors the chain of custody of samples and includes the insertion of blanks (5% of the announced results), duplicates (3% of the announced results), and standard reference material (5% of the announced results) in each batch of samples sent for analysis. Drill core is photographed, logged, and cut in half with one half retained in a secured location for verification purposes and one half shipped for analysis. The entire sample is crushed to 80% passing 2 mm and a riffle split of 250 grams is taken and pulverized to 95% passing 105 µm (RX1). Samples are analyzed by four-acid digestion/ICP-MS package for 36 elements (1F2). Additionally, samples are analyzed for Au using a firing assay from a 50-gram pulp (1A2B-50). Overlimit samples values for zinc (>1%) and Pb (>0.5%) are re-assayed using a four-acid digestion overlimit method with ICP-AES 9 (8-4 Acid over limit). No QA/QC issues were noted with the results reported herein.
