Kirkland Lake Discoveries Reports Additional Assay Results from 2026 Diamond Drilling Program At Mirado Project
Kirkland Lake Discoveries Corp. reported additional assay results from holes from its ongoing 2026 diamond drilling program at the Mirado Project, located approximately 20 km southeast of Kirkland Lake, Ontario. KLM26-010, the southernmost hole in this release, was drilled approximately 120 m south of previously known mineralization, returning multiple high-grade gold intervals, including: 79.63 g/t Au over 2.1 m, including 184.04 g/t Au over 0.8 m; 53.46 g/t Au over 1.4 m, including 165.89 g/t Au over 0.4 m; 1.73 g/t Au over 2.9 m; 3.97 g/t Au over 1.1 m. KLM26-011 intersected 0.98 g/t Au over 62.3 m from 189 m, in a hole collared approximately 100 m west of KLM26-004, extending the broader South Zone mineralized area to the southwest and down-dip. KLM26-011 and KLM26-010 demonstrate two important expressions of the South Zone system: broader shallow mineralization in KLM26-011 and structurally controlled, very high-grade mineralization occurring along the same gold-bearing pathways farther south in KLM26-010. KLM26-008, drilled in the North Zone approximately 75 m east of previously released KLM26-006, returned multiple mineralized intervals over a broad downhole extent, continuing to demonstrate stacked, steeply dipping mineralized structures, including: 0.44 g/t Au over 17.7 m; 0.93 g/t Au over 6.3 m; 1.01 g/t Au over 5.0 m; 1.88 g/t Au over 5.1 m; 0.54 g/t Au over 4.0 m. The new MobileMT, VLF, and total magnetic intensity (TMI) plan maps suggest that the South Zone, North Zone, and southern high-grade intercepts occur within a broader connected structural-geophysical corridor. The new results continue to strengthen Kirkland Lake Discoveries Corp.'s interpretation of Mirado as a broad, structurally controlled gold system developed along persistent mineralized pathways. In the South Zone, drilling has now demonstrated both broad near-surface mineralized zones and the continued lateral extent of the mineralized structural network farther south, highlighting the potential for additional zones of gold mineralization along the same corridor. KLM26-011 is particularly important to the shallow mineralization expansion model, intersecting 0.98 g/t Au over 62.3 m in a hole collared 100 m west of KLM26-004, extending the interpreted broader South Zone mineralized area laterally 100 m to the west and vertically 130 m. Farther south, KLM26-010 demonstrates that the same structural corridor remains fertile and can host narrow, very high-grade intervals, including 79.63 g/t Au over 2.1 m and 53.46 g/t Au over 1.40 m. This supports the interpretation that mineralizing structures persist along strike and to depth, with potential for repeated high-grade and broader mineralized zones beneath and beyond known mineralization. The company is integrating these results with recently completed MobileMT, VLF, and TMI geophysical datasets. Together, the drilling and geophysics support a growing exploration model in which mineralization at Mirado is distributed along a broader structural-geophysical corridor rather than being confined to a single historical resource area. The regional overview of KL South with new MobileMT VLF amplitude shows discovery potential in multiple areas. Regional high-resolution geophysics interpretation and geochemistry programs are underway to provide additional data for modern exploration and AI integration. The plan view, long-section and cross-section of historical and Kirkland Lake Discoveries Corp. drilling show mineralization over 0.2 g/t Au. The 2018 (historical) open pit resource shell is shown in grey. Drill results include: KLM26-007: No reportable composite intervals, South Zone; KLM26-008: 136.4-154.1 m, 17.7 m, 0.44 g/t Au, North Zone; 186.0-190.2 m, 4.2 m, 0.47 g/t Au, North Zone; 235.2-241.5 m, 6.3 m, 0.93 g/t Au, North Zone; 415.0-420.0 m, 5.0 m, 1.01 g/t Au, North Zone, including 415.0-418.0 m, 3.0 m, 1.63 g/t Au, North Zone; 435.0-442.0 m, 7.0 m, 0.52 g/t Au, North Zone; 455.0-460.1 m, 5.1 m, 1.88 g/t Au, North Zone; 531.0-535.0 m, 4.0 m, 0.54 g/t Au, North Zone. KLM26-009: 415.0-416.0 m, 1.0 m, 10.18 g/t Au, South Zone. KLM26-010: 255.9-257.3 m, 1.4 m, 53.46 g/t Au, South Zone, including 256.6-257.0 m, 0.4 m, 165.89 g/t Au, South Zone; 296.0-298.9 m, 2.9 m, 1.73 g/t Au, South Zone, including 298.1-298.9 m, 0.8 m, 4.88 g/t Au, South Zone; 336.5-338.6 m, 2.1 m, 79.63 g/t Au, South Zone, including 337.1-337.9 m, 0.8 m, 184.04 g/t Au, South Zone; 477.8-478.9 m, 1.1 m, 3.97 g/t Au, South Zone; 587.1-588.0 m, 0.9 m, 1.44 g/t Au, South Zone. KLM26-011: 189.0-251.3 m, 62.3 m, 0.98 g/t Au, South Zone, including 241.5-251.3 m, 9.8 m, 3.51 g/t Au, South Zone; 266.2-271.0 m, 4.8 m, 0.35 g/t Au, South Zone; 277.6-285.0 m, 7.4 m, 0.34 g/t Au, South Zone. Reported intervals are calculated using a weighted average grade with a 0.2% Au cutoff. To reflect the continuity of mineralization within the broader system, up to 6.9 m of internal dilution (consecutive material below cutoff) is included within reported composites. True widths are estimated at approximately 80% of the reported core length intervals. At this stage, no top-cutting has been applied to high-grade results. Further drilling is required to generate a robust dataset for variographic analysis, which will be used to mathematically determine appropriate grade capping for future resource estimations. Kirkland Lake Discoveries Corp.'s current interpretation is that the Mirado gold system consists of connected dilation zones developed along persistent structural fluid pathways. In this model, broader gold-bearing zones form where structures open into favourable dilation sites, while narrower high-grade gold intervals can occur along the same structures between or beyond the broader mineralized zones. The broader South Zone mineralization intersected in earlier drilling (including KLM26-001, KLM26-001B, KLM26-002, KLM26-003, and KLM26-004) is interpreted as a major dilation-hosted mineralized area. These holes returned wider zones of mineralization and helped define the main South Zone mineralized body.
