Kirkland Lake Discoveries hits 2.13 g/t Au over 29.0 m at Mirado

Toronto, Ontario--(Newsfile Corp. - August 26, 2026) - Kirkland Lake Discoveries Corp. (TSXV: KLDC) (OTCQB: KLKLF) ("KLDC" or the "Company") reports assay results from four drill holes at the Mirado gold system. South Zone holes KLM26-029 and KLM26-031 extend the zone westward, returning 2.13 g/t Au over 29.0 m and 2.11 g/t Au over 14.1 m , respectively. These results are part of the ongoing drill program at KL South, 18 km south of Kirkland Lake, Ontario, with an additional 19 holes pending.

Highlights

KLM26-029 - 2.13 g/t Au over 29.0 m from 173 m including 3.37 g/t Au over 17.5 m

KLM26-031 - 2.11 g/t Au over 14.1 m from 157 m including 2.74 g/t Au over 10.1 m

KLM26-027 - 4.76 g/t Au over 6.65 m from 8 m

KLM26-028 - 3.89 g/t Au over 2.14 m from 401.3 m

19 holes pending results

Nine from Mirado

Six from MZ target area

Four regional targets

Drill Program Discussion

Recent drilling has successfully identified two distinct growth vectors at the Mirado project, expanding the South Zone to the west and extending the North Zone at depth, see Figures 1 and 2 . Holes KLM26-029 and KLM26-031 intersected broad, gold-bearing intervals from separate collars, extending the interpreted South Zone westward with principal composites of 29.0 m (estimated 23 m true width) and 14.1 m (estimated 11 m true width). Furthermore, hole KLM26-028 successfully encountered mineralization in both interpreted zones, intersecting the South Zone in the upper portion of the hole and the North Zone near the bottom. This deeper intercept, beginning at 401.3 m downhole, significantly extends the North Zone to approximately 365 m vertical depth and further supports the interpreted stacked geometry of the deposit.
