Toronto, Ontario--(Newsfile Corp. - May 20, 2025) - Kirkland Lake Discoveries (TSXV: KLDC) ("KLDC" or the "Company") is pleased to announce that it has received final approval from the TSX Venture Exchange for its recently announced property acquisitions and has kicked off its 2025 exploration season on a series of highly prospective copper-zinc-silver-gold targets in Kirkland Lake, Ontario.

With the technical groundwork in place, permits in hand for key areas, and boots on the ground, KLDC is advancing a large-scale, underexplored VMS system supported by compelling historical drill results, strong geophysical signatures, and multi-element soil anomalies.

TSX Venture Exchange Approves Transactions

On May 8, 2025, the Company received final approval from the TSX Venture Exchange for its acquisitions of the Amikougami and Winnie Lake properties from Val-d'Or Mining Corporation and additional land holdings from private holders. KLDC has now issued:

• 1,750,000 common shares to Val-d'Or Mining Corporation
• 200,000 common shares each to Sudeep Mathew and Charles Gryba

These transactions expand KLDC's footprint in the Blake River Group, immediately adjacent to and along trend with the historical Winnie Lake VMS showing, which has seen minimal modern exploration.

Field Program Underway – Drilling Planned for Late June

KLDC's field team is now active on-site conducting:

• Access preparation
• Geological mapping, sampling and ground truthing
• Final targeting for the upcoming drill program, expected to begin late June

Permits have been received for core areas around the Winnie Lake Pluton, with applications already submitted for additional newly acquired ground (see Figure 1).

VMS Potential: Soils, Magnetics, and Historical Mineralization Align

KLDC's exploration thesis centers around a potential volcanogenic massive sulfide (VMS) system peripheral to the Winnie Lake Pluton – a felsic intrusion with surrounding magnetic highs and coincident multi-element geochemical anomalies.

"With final approvals in place and the field season underway, we are laser-focused on drilling what we believe is a significant VMS system that's been overlooked for decades," said Stefan Sklepowicz, CEO of Kirkland Lake Discoveries. "We've got all the right ingredients — a synvolcanic felsic intrusive, with coincident magnetic highs and geochemical anomalies suggesting it may have played a role in local mineralizing systems— and we're excited to put the first modern holes into these targets in over 30 years."

Key highlights include:

• Copper-zinc-silver-gold anomalies in soils concentrated along the margins of the pluton.
• Prominent magnetic highs surrounding the margins of the pluton - In one of these magnetic highs, Pamorex Resources 1989 drill hole intersected massive sulfide mineralization grading:
  • 1.93% Cu, 1.51% Zn, 0.786 g/t Au and 12.1 g/t Ag over 18.41 m (from 11.89 m)
  • 2.44% Cu, 3.63% Zn, 1.376 g/t Au and 16.5 g/t Ag over 10.12 m (from 31.15 m)
    within a broader intercept of 1.34% Cu, 1.53% Zn, 0.638 g/t Au, 9.5 g/t Ag over 47.12 m (from 11.89 m)

KLDC plans to follow up on these results with modern geophysics and systematic drilling.
