Kirkland Lake Discoveries extends Mirado: 79.63 g/t Au over 2.1 m south

Toronto, Ontario--(Newsfile Corp. - June 23, 2026) - Kirkland Lake Discoveries Corp. (TSXV: KLDC) (OTCQB: KLKLF) ("KLDC" or the "Company") is pleased to report 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. Highlights 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 62.3m 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 (see Figure 1 ) The new results continue to strengthen KLDC's interpretation of Mirado as a broad, structurall
