LAURION Extends Drilling into Untested Ground Linking Brenbar and Sturgeon River Mine Corridors at Ishkoday (TheNewswire) Toronto, Ontario – November 25, 2025 – TheNewswire - LAURION Mineral Exploration Inc. (TSX.V: LME | OTC: LMEFF) (“LAURION” or the “Corporation”) is pleased to announce encouraging results from its 7,700-metre Summer 2025 drill exploration program at the 100%-owned Ishkõday Project, located 220 km northeast of Thunder Bay in Greenstone, Ontario. The first five drill results were announced in the Corporation’s press releases dated August 19, 2025 and September 23, 2025, respectively, which targeted the high-grade gold-bearing vein systems of the Sturgeon River Mine area. Reference is also made to the Corporation’s press releases dated September 5, 2025, May 27, 2025 and May 8, 2025. The reported drill holes below, LME25-063, LME25-064, LME25-065 and LME25-066, total 1,806 m. The holes were designed to evaluate the northeast extension of the mineralized system at the historic Brenbar Mine, with hole LME25-063, and then stepping out to the northeast of the Brenbar historic mine shaft targeting the untested M50 Quartz vein series with further drill holes. Highlights of Drill Holes LME25-063, LME25-065 and LME25-066 LME25-063 0.7 m @ 2.67 g/t Au from 139.50 m to 140.20 m; LME25-063 0.5 m @ 1.26 g/t Au from 393.40 m to 393.90 m; LME25-065 0.50 m @ 1.78 g/t Au from 91.10 m to 91.60 m; LME25-065 1.80 m @ 0.95 g/t Au from 149.60 m to 151.40 m, including: 0.80 m @ 1.90 g/t Au from 150.60 m to 151.40 m; LME25-065 0.50 m @ 1.32 g/t Au from 292,30 m to 292.80 m; LME25-066 1.50 m @ 1.02 g/t Au from 272,50 m to 274.00 m; and LME25-066 0.70 m @ 2.42 g/t Au and 1.90 Au/t from 389.0 m to 389.70 m. “ While these results represent the early stages of testing in a geologically complex corridor, their significance lies in extending our knowledge of mineralization continuity between the historic Brenbar and Sturgeon River Mine areas, ” stated Cynthia Le Sueur-Aquin, President and CEO of LAURION. “This is the first time drilling has been completed across this untested structural corridor, and it is yielding valuable geological insight with oriented core, that will guide the next phase of our exploration program. Our focus remains on defining the broader mineralized system that links multiple historic mine zones, ultimately positioning Ishkōday as a district-scale gold and base metal opportunity.” Table of Assays for Drill Holes for LME25-063 to LME25-066 Hole ID From (m) To (m) Core Length (m) Au (g/t) LME25-063 11.6 12.1 0.5 0.38 LME25-063 26.80 27.5 0.7 0.87 LME25-063 33.5 34.5 1.0 0.45 LME25-063 47.0 48.0 1.0 0.34 LME25-063 85.0 85.5 0.5 0.91 LME25-063 139.5 140.2 0.7 2.67 LME25-063 144.9 145.5 0.6 0.94 LME25-063 228.4 228.9 0.5 0.58 LME25-063 262.5 264.0 1.5 0.75 LME25-063 251.5 283.0 1.5 0.52 LME25-063 393.4 393.9 0.5 1.26 LME25-064 22.5 23.1 0.6 0.29 LME25-064 55.0 56.0 1.0 0.92 LME25-064 83.0 84.5 1.5 0.20 LME25-064 151.0 152.0 1.0 0.20 LME25-064 218.8 219.3 0.5 0.26 LME25-064 246.0 247.1 1.1 0.23 LME25-064 313.0 313.5 0.5 0.97 LME25-064 331.0 332.0 1.0 0.27 LME25-064 354.0 354.5 0.5 0.25 LME25-064 356.1 356.6 0.5 0.70 LME25-065 5.7 6.2 0.5 0.71 LME25-065 8.0 8.8 0.8 0.31 LME25-065 15.5 17.0 1.5 0.23 LME25-065 40.3 40.9 0.6 0.48 LME25-065 54.5 55.1 0.6 0.23 LME25-065 64.7 65.4 0.7 0.27 LME25-065 75.4 76.0 0.6 0.69 LME25-065 91.1 91.6 0.5 1.78 LME25-065 94.0 95.0 1.0 0.32 LME25-065 149.6 151.4 1.8 0.95 including 150.6 151.4 0.8 1.90 LME25-065 20.08 209.0 1.0 0.44 LME25-065 223.5 224.0 0.5 0.20 LME25-065 235.0 236.0 1.0 0.40 LME25-065 243.5 245.0 1.5 0.29 LME25-065 292.3 292.8 0.5 1.32 LME25-065 309.9 310.4 0.5 0.25 LME25-065 319.7 320.9 1.2 0.21 LME25-065 319.7 320.2 0.5 0.32 LME25-065 365.0 365.5 0.5 0.27 LME25-065 391.2 391.7 0.5 0.22 LME25-065 417.3 417.8 0.5 0.80 LME25-065 487.4 488.2 0.8 0.38 LME25-066 5.46 6.5 1.04 0.21 LME25-066 13.3 14.75 1.45 0.37 LME25-066 85.0 89 4.0 0.26 LME25-066 86.25 87.1 0.85 0.53 LME25-066 117.0 118 1.0 0.67 LME25-066 223.7 225.5 1.8 0.25 LME25-066 251.5 252.1 0.6 0.34 LME25-066 257.4 258.15 0.75 0.46 LME25-066 272.5 274.0 1.5 1.02 LME25-066 303.0 303.5 0.5 0.41 LME25-066 307.8 308.3 0.5 0.94 LME25-066 310.2 310.7 0.5 0.70 LME25-066 324.6 325.1 0.5 0.46 LME25-066 327.4 327.9 0.5 0.93 LME25-066 339.0 340.0 1.0 0.25 LME25-066 389.0 389.7 0.7 2.42 LME25-066 400.0 400.65 0.65 0.84 LME25-066 413.8 414.3 0.5 0.21 LME25-066 465.2 465.8 0.6 0.20 Note: (Intervals represent core length.
