Toronto, Ontario--(Newsfile Corp. - June 23, 2026) - Kirkland Lake Discoveries Corp. (TSXV: KLDC)
(OTCQB: KLKLF) ("KLDC" or the "Company") is pleased to report additional assay results from holes
from its ongoing 2026 diamond drilling program at the Mirado Project, located approximately 20 km
southeast of Kirkland Lake, Ontario.
Highlights
KLM26-010
, the southernmost hole in this release, was drilled approximately
120 m south of
previously known mineralization
, returning multiple high-grade gold intervals, including:
79.63
g/t Au over 2.1 m
, including
184.04 g/t Au over 0.8 m
53.46 g/t Au over 1.4 m
, including
165.89 g/t Au over 0.4 m
1.73 g/t Au over 2.9 m
3.97 g/t Au over 1.1 m
KLM26-011 intersected 0.98 g/t Au over 62.3m from 189 m
, in a hole collared approximately
100 m west of KLM26-004
, extending the broader South Zone mineralized area
to the
southwest and down-dip
KLM26-011 and KLM26-010 demonstrate two important expressions of the South Zone
system
: broader shallow mineralization in KLM26-011 and structurally controlled, very high-grade
mineralization occurring along the same gold-bearing pathways farther south in KLM26-010
KLM26-008
, drilled in the
North Zone
approximately
75 m east of previously released KLM26-
006
, returned multiple mineralized intervals over a broad downhole extent, continuing to
demonstrate stacked, steeply dipping mineralized structures, including:
0.44 g/t Au over 17.7 m
0.93 g/t Au over 6.3 m
1.01 g/t Au over 5.0 m
1.88 g/t Au over 5.1 m
0.54 g/t Au over 4.0 m
The new MobileMT, VLF, and total magnetic intensity (TMI) plan maps suggest that the South
Zone, North Zone, and southern high-grade intercepts occur within a broader connected structural-
geophysical corridor
(see
Figure 1
)
The new results continue to strengthen KLDC's interpretation of Mirado as a broad, structurally controlled
gold system developed along persistent mineralized pathways. In the South Zone, drilling has now
demonstrated both broad near-surface mineralized zones and the continued lateral extent of the
mineralized structural network farther south, highlighting the potential for additional zones of gold
mineralization along the same corridor.
KLM26-011 is particularly important to the shallow mineralization expansion model, intersecting 0.98 g/t
Au over
62.3 m
in a hole collared
100 m west of KLM26-004
, extending the interpreted broader South
Zone mineralized area laterally
100 m to the west and vertically 130 m
. Farther south, KLM26-010
demonstrates that the same structural corridor remains fertile and can host narrow, very high-grade
intervals, including
79.63 g/t Au over 2.1 m
and
53.46 g/t Au over 1.40 m
. This supports the
interpretation that mineralizing structures persist along strike and to depth, with potential for repeated
high-grade and broader mineralized zones beneath and beyond known mineralization
(see
Figure 2
and
Table 1
)
.
The Company is integrating these results with recently completed MobileMT, VLF, and TMI geophysical
datasets. Together, the drilling and geophysics support a growing exploration model in which
mineralization at Mirado is distributed along a broader structural-geophysical corridor rather than being
confined to a single historical resource area.
Stefan Sklepowicz, Chief Executive Officer, commented: "These results continue to build the case that
Mirado is not a single isolated historical resource, but a broader gold system with multiple mineralized
structures and repeated mineralized zones. KLM26-011 expands the South Zone with a broad gold-
bearing interval, while KLM26-010 demonstrates that the corridor remains capable of producing very
high-grade gold farther south. With a second drill now turning and regional prospecting underway, we are
accelerating our efforts to define the larger scale of the system."

Reported intervals are calculated using a weighted average grade with a 0.2 g/t Au cutoff. To reflect the
continuity of mineralization within the broader system, up to 6.9 m of internal dilution (consecutive
material below cutoff) is included within reported composites. True widths are estimated at
approximately 80% of the reported core length intervals. At this stage, no top-cutting has been applied to
high-grade results. Further drilling is required to generate a robust dataset for variographic analysis,
which will be used to mathematically determine appropriate grade capping for future resource
estimations.
Emerging connected dilation-zone model
KLDC's current interpretation is that the Mirado gold system consists of connected dilation zones
developed along persistent structural fluid pathways. In this model, broader gold-bearing zones form
where structures open into favourable dilation sites, while narrower high-grade gold intervals can occur
along the same structures between or beyond the broader mineralized zones.
In simple terms: hot, gold-rich fluids flowed through a network of underground 'plumbing,' pooling into
large, broad zones where the rock opened up, and leaving narrow, highly concentrated streaks of gold in
the tighter cracks connecting them
The broader South Zone mineralization intersected in earlier drilling (including KLM26-001, KLM26-
001B, KLM26-002, KLM26-003, and KLM26-004) 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.
KLM26-011 now extends this broader shallow South Zone mineralized area approximately
100 m west
of KLM26-004
, returning 0.98 g/t Au over
62.3 m from 189 m
(see
Figure 3
)
. This result is significant
because it demonstrates that broader South Zone mineralization is not limited to the previously drilled
KLM26-001 to KLM26-004 area and may repeat along the same structurally controlled fluid pathways.

Farther south, KLM26-010 demonstrates that the structural corridor remains fertile where mineralization
is expressed as narrow, very high-grade intervals rather than broad continuous mineralized envelopes.
KLM26-010 was drilled approximately
50 m south of KLM26-009
and approximately
120 m south of
previously known mineralization
, highlighting the potential for additional high-grade mineralization
along the southern continuation of the system.
KLM26-007 and KLM26-009 are also important to this model. Although they did not return broad
significant composite intervals, they help constrain the geometry of the system and suggest that the
broader dilation zones may pinch, step, or be offset along the controlling structures. This information is
valuable for targeting additional mineralized zones along strike and down plunge.
Together, the South Zone results support a positive expansion model for Mirado, where gold
mineralization is interpreted to occur along a connected structural corridor with broader mineralized
zones developed in favourable structural sites and narrower high-grade intervals representing the
continued lateral expression of the same mineralized network. This interpretation provides KLDC with a
stronger framework for targeting additional mineralized zones along strike, down-dip, and within
prospective structural step-over areas.
North Zone confirms stacked vertical structures
In the North Zone, KLM26-008 was drilled approximately
75 m east of KLM26-006
and continues to
support KLDC's interpretation of stacked, steeply dipping mineralized structures. The hole intersected
repeated gold-bearing intervals over a broad downhole extent, indicating that mineralization is
distributed through multiple structural panels rather than a single horizon.
This is significant because it suggests the North Zone represents a separate but related mineralized
area within the broader Mirado system. 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.
Geophysical interpretation supports expansion model
The Company is integrating the new drill results with recently completed MobileMT, VLF, and TMI
geophysical datasets. Initial interpretation suggests that the 2026 drilling is testing a corridor developed
along a magnetic transition between lower magnetic response to the west and stronger magnetic
response to the east.
The VLF and MobileMT apparent conductivity maps show response features in and around the drilled
areas, including the South Zone, North Zone, and the southern KLM26-010 area. KLDC interprets these
geophysical patterns as potentially reflecting structural breaks, lithological contacts, or zones of
enhanced permeability that may have influenced the movement of mineralizing fluids.
The combination of drilling and geophysics supports the Company's view that Mirado has potential for
additional connected mineralized zones beyond the historically drilled resource area.
KLDC will use this integrated geological and geophysical model to target additional step-out drilling
along interpreted structural corridors, with a focus on identifying further dilation zones capable of hosting
broader mineralization and high-grade shoots.
Project Updates
KLDC is pleased to report that a second diamond drill is now turning at the Mirado Project. The second
drill, operated by Chibougamau Drilling, increases the Company's exploration capacity at a key point in
the 2026 program and provides additional flexibility to advance priority targets across the South Zone,
North Zone, and broader Mirado structural corridor.
The Company has also commenced its 2026 prospecting program, with two field teams from Dynamite
Geological Services now active on the property. This work is focused on testing high-priority regional
targets generated from the integration of historical geological data, previous exploration results, and
newly acquired MobileMT geophysical data. These targets include priority structural, conductive, and
magnetic features interpreted to represent potential extensions or repetitions of the Mirado gold system
beyond the currently drilled areas.
The addition of a second drill and the launch of regional prospecting positions KLDC to maintain strong
exploration momentum at Mirado. This expanded field program is designed to both continue defining
and extending known mineralized zones and advance new regional targets toward drill-ready status.
KLDC believes this integrated approach provides a strong platform for potential discovery growth and
continued value creation at the Mirado Project.

Data Verification & Quality Assurance/Quality Control (QA/QC)
Gold analyses were completed on ½ NQ Core at Paragon Geochemical using Chrysos PhotonAssay™
technology, a fast, non-destructive analytical method that utilizes high-energy X-rays to directly measure
gold content in large (~500 g) samples. The larger sample mass used in PhotonAssay is designed to
reduce sampling variability associated with coarse gold mineralization and provides rapid, non-
destructive gold analysis while also enabling faster turnaround times.

Samples returning gold values above the 350 g/t upper detection limit of the PhotonAssay method are
reanalyzed using a 1 kg screen fire assay, wherein the sample is sieved at 110 microns, the coarse (+)
fraction is analyzed by gravimetric methods, and the fine (-) fraction is analyzed in duplicate by AAS, with
the combined results providing a representative total gold value, particularly in samples containing
coarse gold.
Drill program design, QA/QC, and interpretation of results are conducted by qualified persons consistent
with National Instrument 43-101 and industry best practices. Certified reference standards and blanks
are inserted into the sample stream at regular intervals, approximately one control sample per twenty
samples, to monitor analytical accuracy and precision.
Reported intervals are calculated using a weighted average grade with a 0.2 g/t Au cutoff. To reflect the
continuity of mineralization within the broader system, up to 6.9 m of internal dilution (consecutive
material below cutoff) is included within reported composites. No top-cutting has been applied to high-
grade results. True widths are estimated at approximately 80% of the reported core length intervals.
Assays are uncut except where indicated.
