KLDC intercepts 103 m mineralization; 5.66 g/t Au over 18.2 m at Mirado

Toronto, Ontario--(Newsfile Corp. - April 16, 2026) - Kirkland Lake Discoveries Corp. (TSXV: KLDC) (OTCQB: KLKLF) ("KLDC" or the "Company") is pleased to announce assay results from its ongoing 2026 diamond drilling program at the past-producing Mirado property, located 20 km southeast of Kirkland Lake, Ontario. The first drill hole targeting the South Zone at Mirado, confirms mineralization originally identified by Golden Shield Resources in the 1980s and is integral to advancing and expanding the modern understanding of this mineralizing system. Drilling continues at Mirado with a fence of holes testing the extent of mineralization along strike and at depth at the South Zone and testing mineralization at the North Zone ( see Figure 1 ) .

Highlights KLM26-001 1.10 g/t Au over 15.1 m from 39.6 m to 54.6 m 5.66 g/t Au over 18.2 m from 62.0 m to 80.2 m, including 23.03 g/t Au over 4.3 m 3.30 g/t Au over 18.7 m from 96.7 m to 115.3 m, including 5.49 g/t Au over 4.9 m, and 3.92 g/t over 4.1 m KLM26-001B Wedge 1.78 g/t Au over 23.9 m from 88.5 m to 112.5 m Visible gold observed in multiple holes ( see Figure 2) Broad zones of continuous mineralization Expedited assay results through Paragon and use of PhotonAssay ™ KLDC Chief Executive Officer Stefan Sklepowicz commented , " Intercepting 5.66 g/t Au over 18.2 m in our very first hole at Mirado is an exceptional start to this program. These results confirm a robust gold system with the potential for both bulk-tonnage scale and high-grade zones. With mineralization open in multiple directions, we believe we are only beginning to unlock value at KL South.

" " One of the fascinating things about this project is that the highlight table doesn't always tell the story. We have an extremely broad and prolific system here at Mirado. Historically this may have been missed, and this drill hole exemplifies the potential scale with 103 m of continuous mineralization ," commented Denis Laviolette, KLDC Executive Chairman Figure
