Toronto, Ontario--(Newsfile Corp. - April 1, 2026) -
Kirkland Lake Discoveries Corp. (TSXV: KLDC)
(OTCQB: KLKLF)
("KLDC" or the "Company") is pleased to announce the start of its 2026 diamond
drilling program at the past-producing Mirado property, located 20 km southeast of Kirkland Lake,
Ontario. This campaign marks the first systematic and fully integrated, large-scale exploration of the
asset in over a decade, aiming to expand known high-grade zones and test new structural targets.
A Systematic Approach to a Proven Asset
The Mirado property represents a brownfield exploration opportunity within the Abitibi Greenstone Belt
with a production history dating back to the 1920s. While historical development was frequently
interrupted by external macroeconomic cycles, resulting in a substantial historical dataset, the system
remains largely untested using modern exploration approaches.
1940s Era: Between 1937 and 1943, Yama Gold Mines produced 3,227 oz Au at a recovered
grade of 0.15 oz/t. Operations were suspended during the post-war period primarily due to the
fixed gold price environment of the time, which constrained underground development.
1980s Development: Golden Shield Resources conducted significant work in the mid-1980s,
including 32,000 ft of drilling and extensive underground drifting. Development was halted following
the 1987 market downturn, which limited the availability of venture capital for junior producers,
despite the presence of surface stockpiles.
Modern Consolidation: Following the consolidation of the property in 2012, further advancement
was deferred during the 2013 commodity price correction.
Kirkland Lake Discoveries is now revisiting Mirado with a systematic, fully integrated approach, applying
modern geological modeling and exploration techniques to advance a known gold system with a well-
established but historically phased exploration record.

Mineralization Style and Geological Context
The Mirado system comprises two distinct mineralization styles associated with the North and South
Zones. The North Zone hosts semi-conformable, stratigraphically controlled sulphide mineralization
within felsic volcaniclastics, while the South Zone is defined by discordant, structurally controlled gold
mineralization hosted in quartz-chlorite vein arrays. Together, these styles reflect a stratigraphic system
that has been overprinted and locally enhanced by later structural controls.
The following intercepts represent the historical and modern data points that define the core mineralized
zones and serve as the primary targets for the 2026 confirmatory drill program:

Note on historical data:
The drill results presented in the list above (Table 1) are
historical in nature
and have been compiled from historical drill logs, government assessment reports, and previous
operator records and may include uncapped values. These results have not been verified by a "Qualified
Person" (QP) as defined by
National Instrument 43-101 (NI 43-101)
and should not be relied upon as
current. The Company has not yet conducted sufficient re-assaying or independent validation of the
original drill core or lab certificates to ensure the accuracy or validity of these results. While Kirkland
Lake Discoveries Corp. believes these records provide an important indication of the property's
mineralization potential, they are provided for informational purposes only until modern confirmatory
drilling and QA/QC protocols are completed during the 2026 campaign.
CEO's Vision: A New Era for Mirado
"The Mirado property has a history of technical success that was frequently interrupted by external
market cycles rather than geological outcomes," said
Stefan Sklepowicz, CEO of Kirkland Lake
Discoveries Corp.
"Our objective for the 2026 campaign is to apply modern exploration standards to a
system that has historically been advanced in a fragmented manner. By integrating ninety years of data
into a cohesive model, we aim to identify the primary controls on mineralization and systematically test
for extensions at depth. This program represents a disciplined step forward in defining the true scale and
potential of the Mirado asset."
Expedited Results: The Move to Paragon & PhotonAssay™
To ensure rapid market communication and superior analytical precision, KLDC has made the strategic
decision to move forward with
Paragon Geochemical
to utilize
Chrysos PhotonAssay™
technology
for the 2026 program at KL South.
Unlike traditional fire assay, PhotonAssay™ uses high-energy X-rays to excite atomic nuclei, providing a
non-destructive, faster, and more environmentally friendly analysis of larger (500g) samples. This is
particularly critical for the Mirado property, where the presence of "nuggety" or coarse gold can lead to
grade variability in smaller samples. By utilizing this state-of-the-art technology, the Company expects to
significantly reduce turnaround times for drill results while improving the statistical reliability of high-grade
intercepts.
Objectives for 2026
The 2026 program is designed to move the Mirado property toward a modern resource update through
a disciplined, four-pronged approach:
Database Validation and Infill:
Verify historical high-grade logs, execute infill drilling and provide
the modern data density required for NI 43-101 compliance.
Targeted Depth Extensions:
Test projected high-grade chutes below 250 where most historical
drilling stopped.
Strike and Zone Expansion:
Investigate the lateral continuity of the MZ Zone to the west and
evaluate the polymetallic potential of the North Zone to identify incremental growth opportunities.
Structural Synthesis:
Integrate 90 years of fragmented historical records into a unified 3D
geological model to refine drill targeting and identify potential sub-surface extensions overlooked
by previous operators.
By operating in a Tier-1 mining jurisdiction with a focused exploration budget, Kirkland Lake Discoveries
Corp. is committed to advancing Mirado from a historical prospect into a modern, well-defined gold
asset in the Abitibi Greenstone Belt.

About Kirkland Lake Discoveries Corp.
Kirkland Lake Discoveries Corp. (TSXV: KLDC) (OTCQB: KLKLF) has assembled a 420-km²
exploration portfolio in the Kirkland Lake region of Ontario's Abitibi Greenstone Belt, one of the most
prolific mining districts in the world. The Company's properties span key fault zones, geophysical
anomalies, and volcanic-sedimentary contacts within the Blake River Group, a highly prospective
assemblage known to host both gold and polymetallic massive-sulphide deposits.
With exploration permits now in place, KLDC is positioned to advance a strong pipeline of drill-ready
targets at KL South, KL West and KL East, supported by multiple anomalous soil trends, historical
mineral showings, and structurally controlled intersections.
