[{"type":"text","content":" Toronto, Ontario--(Newsfile Corp. - May 4, 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. Highlights: KLM26-003 0.87 g/t Au over 27 m from 13 m to 40 m 0.26 g/t Au over 16 m from 81.5 m to 97.5 m 0.25 g/t Au over 32.9 m from 112.6 m to 145.5 m KLM26-004 39.35 g/t Au over 16.4 m from 53.6 m to 70 m, including: 106.9 g/t Au over 6.0 m from 55 m and including 1,670 g/t Au over 0.38 m from 58.62 m 2.22 g/t Au over 26.1 m from 78.7 m to 104.8 m, including: 3.75 g/t Au over 13.5 m from 91.3 m 40-m step out south from hole KLM26-002 High-grade mineralization Six holes pending using Chrysos PhotonAssayâ„¢ for expedited results Results from drill hole KLM26-004, located approximately 40 metres southeast of KLM26-002, confirm the lateral continuity of the South Zone mineralized system and demonstrate the presence of high-grade shoots within the broader mineralized envelope with geological continuity (see Figure 1). Drill hole KLM26-003, positioned between KLM26-001 and KLM26-002, returned 0.87 g/t Au over 27 m from 13 m, 0.26 g/t Au over 16 m from 81.5 m, and 0.25 g/t Au over 32.9 m from 112.6 m, further supporting continuity of the mineralized envelope along strike (see Table 1). The combination of the broad, continuous mineralization intersected in KLM26-002 (1.01 g/t Au over 121 m) and the higher-grade, visible gold-bearing intervals in KLM26-004 (see Figure 2 and Figure 3) highlights the role of structural controls, sulphide concentration, and quartz-carbonate veining in upgrading gold grades within the system. Chief Executive Officer, Stefan Sklepowicz, commented, \"As we progress into new areas at Mirado, we are seeing the exact geological signatures we had hoped for, broad, continuous mineralization punctuated by high-grade intercepts. KLM26-004 clearly demonstrates the potential of this system. With six additional holes pending, we are eager to see how these results continue to define the scale of this project.\" Executive Chairman, Denis Laviolette, commented, \"Historically, Mirado was interpreted as a series of discrete, stacked lenses. Our recent drilling, however, demonstrates that gold mineralization is f...
