Mirado

On June 23, 2026, Kirkland Lake Discoveries Corp. (“KLDC”) announced assay results from its ongoing2026 diamond drilling program at the past-producing Mirado property. KLDC reported that the broader South Zone mineralization intersected in earlier drilling 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. Drill hole KLM26-011 extended this broader shallow South Zone mineralized area approximately 100 m west of KLM26-004. In the North Zone, KLDC stated that KLM26-008 was drilled approximately 75 m east of KLM26-006 and continues to support KLDC’s interpretation of stacked, steeply dipping mineralized structures. When integrated with the South Zone, the expansion in KLM26-011, and the southern high-grade intercepts in KLM26-010, the results support a larger exploration model in which multiple mineralized zones may be connected by a common structural and hydrothermal framework.

On May 25, 2026, KLDC announced assay results from its ongoing 2026 diamond drilling program at the Mirado property. KLDC stated that assay results from drill holes KLM26-005 and KLM26-006, and visuals from KLM26-010 continue to strengthen KLDC’s evolving geological model at Mirado and highlight the growing scale of both the South and North Zone systems. KLDC also stated that winter drilling at KL West and KL South came in under budgeted, as a result KLDC has added an additional 5,000 m of drilling at KL South, bringing the total program up to 30,000 m.

On May 4, 2026, KLDC announced additional assay results with Hole KLM26-004 highlights included 39.35 g/t Au over 16.4m from 53.6 m to 70 m, including 106.9 g/t Au over 6.0 m and 1,670 g/t over 0.38 m, and 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. KLDC further stated that results from drill hole KLM26-004, located approximately 40 m 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.

On April 16, 2026, and April 23, 2026, KLDC announced assay results from its first and second drill holes from its ongoing 2026 diamond drilling program at the Mirado property. Hole KLM26-001 highlights included 5.66 g/t Au over 18.2 m, including 23.03 g/t Au over 4.3 m. The second drill hole, targeting the South Zone at Mirado, stepped out 75 m southeast of KLM26-001 and confirmed continuous mineralization with 1.01 g/t Au from 11.0 m to 132.0 m, including a high-grade interval of 7.41 g/t over 4.8 m from 74.2 m. Ongoing drilling will continue to focus on step-out targeting along strike and at depth, while systematically evaluating the down-plunge potential of the South Zone and testing geophysical targets, including the deep IP anomaly.
