Kirkland Lake Discoveries Intersects 2.46 g/t Au Over 14.7 m in New Fault Zone; 180 m Step-Out Expands Mirado South MineralizationMay 25, 2026 7:00 AM
NewsfileToronto, Ontario--(Newsfile Corp. - May 25, 2026) - Kirkland Lake Discoveries Corp. (TSXV: KLDC) (OTCQB: KLKLF) ("KLDC" or the "Company") is pleased to announce assay results from its ongoing 2026 diamond drilling program at the past-producing Mirado property, located 20 km southeast of Kirkland Lake, Ontario.Highlights:KLM26-0050.25 g/t Au over 11.8 m from 16.8 m to 28.5 m And 14.72 g/t Au over 0.8 m from 72.2 m to 73.0 m And 0.40 g/t Au over 8.8 m from 123.4 m to 132.2 mAnd 1.35 g/t Au over 4.2 m from 158.5 m to 162.7 mKLM26-0060.82 g/t Au over 24.0 m from 160.0 m to 184.0 mAnd 0.76 g/t Au over 13.0 m from 286.3 m to 299.3 mAnd 2.46 g/t Au over 14.7 m from 345.1 m to 359.8 m, including:12.52 g/t Au over 1.8 m from 345.1 m to 346.9 m Multiple high-grade interceptsKLM26-010Visible gold observed at 257 m downhole; this drill hole is a step-out of 180 m from historical resource limitsDrilling resumes at KL South with program expanded to 30,000 m due to under-budget winter program efficienciesAssay results from drill holes KLM26-005 and KLM26-006, and visuals from KLM26-010 continue to strengthen KLDC's evolving geological model at Mirado, highlight the growing scale of both the South and North Zone systems and provide a regional outlook for the remainder of KL South (see Figure 1).Results from drill hole KLM26-005, located approximately 40 m southeast of KLM26-004, 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. Drill hole KLM26-006 is the first hole testing the upper portion of the North Zone while undercutting the South Zone and successfully extending the stacked North Zone mineralized structures by approximately 125 m vertically (see Figure 2). The hole intersected multiple broad intervals of gold mineralization associated with quartz-carbonate veining and sulphide mineralization hosted within altered volcanic units. A new zone was identified at 345 m associated with the Mirado fault indicating that both sides of the fault and the fault itself are mineralized (see Table 1). Drill hole KLM26-010 the southernmost hole drilled to date, is a major step forward for the South Zone model. The hole intersected visible gold at approximately 257 m downhole within quartz-carbonate-pyrite veining and strongly altered volcanic rocks. This interval aligns with KLDC's updated model for the plunging South Zone mineralized system, approximately 180 m south of the historical resource boundary, providing an exciting validation of the Company's interpretation and increasing confidence in the potential to expand the system along plunge and at depth. The Company cautions that the presence of visible gold mineralization is not indicative of high-grade gold assays and that drill core samples will be or have been submitted to a certified laboratory for analysis of gold content. Assay values for the discussed intervals will be released when available. All intervals are downhole depths, and true widths are not known at this time. (see Figure 2 and Figure 3).The winter drilling at KL West and KL South came in under budget, $200/m all-in, and as a result the Company has added an additional 5,000 m of drilling at KL South to bring the total program up to 30,000 m. The spring melt conditions were excellent and drilling at KL South has resumed, targeting the western expansion of mineralization and beneath the historical deposit.Chief Executive Officer, Stefan Sklepowicz, commented, "These latest drill results continue to demonstrate the continuity and scale of the Mirado hydrothermal system. Hole KLM26-006, in particular, returned multiple broad mineralized intervals with embedded higher-grade zones, reinforcing our interpretation that the South Zone hosts a robust structurally controlled gold system with significant expansion potential.""Equally important is the observation of visible gold in KLM26-010, approximately 180 metres south of the historical resource shell. This represents one of the largest step-outs completed to date and strongly supports our belief that mineralization remains open well beyond the historically constrained footprint."Figure 1 - Regional overview of KL South.

To reflect the continuity of mineralization within the broader system, up to 3.0 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. Mineralization Style and Geological ContextSouth Zone Expansion DrillingDrill holes KLM26-005 and KLM26-010 were designed to evaluate the southern extension of the South Zone mineralized corridor and test continuity beneath and beyond the historical resource shell. Current interpretation suggests the South Zone consists of multiple stacked or en-echelon high-grade shoots rather than a single continuous body, with higher-grade mineralization developing where quartz-carbonate veining, sulphide enrichment, and structural preparation become concentrated within the broader hydrothermal system. Current drilling and 3D modelling indicate these shoots plunge west to west-southwest (approximately 240°-260°) at an interpreted angle of approximately 50° within a steeply dipping structural corridor. Recent drilling continues to refine the geometry, continuity, and predictability of these mineralized domains. KLM26-005 intersected multiple zones of gold mineralization hosted within strongly altered and veined volcanic rocks. The hole returned several broad mineralized intervals including 1.35 g/t Au over 4.2 m, 0.40 g/t Au over 8.8 m, and 0.25 g/t Au over 11.8 m, in addition to a localized higher-grade interval of 14.72 g/t Au over 0.8 m. Drilled approximately 40 m southwest of previously released hole KLM26-004, KLM26-005 is interpreted to have undercut the core of the west-plunging mineralized shoots, further constraining the geometry of the South Zone system while confirming the presence of broad lower-grade gold enrichment outside the interpreted higher-grade shoot domains.KLM26-010 is one of the most significant holes drilled at Mirado to date. The hole intersected multiple gold-bearing quartz-carbonate vein zones within a broad altered volcanic package, including visible gold associated with sulphide-rich veining at approximately 257 m downhole. Importantly, this intersection coincided with the area where KLDC's updated geological model had projected the continuation of the plunging South Zone mineralized system, based on a reinterpretation of historical drilling data and structural controls.The occurrence of visible gold, approximately 180 m south of the historical resource boundary, strongly validates the Company's evolving interpretation and materially increases confidence in Mirado's expansion potential at depth and along plunge. The result suggests the system remains open and supports the Company's strategy of targeting structurally controlled high-grade shoots within a much larger mineralized envelope. Assays are pending, and the Company cautions that visible gold is not necessarily indicative of final assay grades.Figure 3 - Visible gold occurrences in KLM26-010 at 257 mTo view an enhanced version of this graphic, please visit:
https://images.newsfilecorp.com/files/5701/298692_d8ff4e6dc4e1c859_003full.jpgNorth Zone and Structural ContinuityThe results from KLM26-006 further define the near-vertical stacked mineralized structures characteristic of the North Zone, extending previously identified mineralization along the eastern edge of the zone by approximately 125 m vertically. These structures are now beginning to demonstrate vertical continuity exceeding 100 m, reinforcing the scale and consistency of the North Zone system.KLM26-006 successfully intersected multiple broad intervals of gold mineralization associated with quartz-carbonate veining and sulphide mineralization hosted within altered volcanic units. The hole returned 2.46 g/t Au over 14.69 m, including 12.52 g/t Au over 1.8 m and 6.73 g/t Au over 1.8 m, as well as additional broad intervals grading 0.82 g/t Au over 24.0 m and 0.76 g/t Au over 13.0 m. Several additional localized higher-grade intervals were also encountered throughout the hole (see Figure 4).Mirado Fault ZoneA particularly significant outcome from KLM26-006 was the previously mentioned intersection of the interpreted Mirado Fault Zone between approximately 345.1 m and 354.2 m downhole. This structure is interpreted to separate the South and North Zone mineralized domains and has seen very limited historical drill testing despite its potential importance as a major fluid pathway within the Mirado system.The interval returned strong gold mineralization grading 2.46 g/t Au over 14.7 m, including 12.52 g/t Au over 1.8 m and 6.73 g/t Au over 1.8 m, associated with intense quartz-carbonate veining, strong alteration, and localized semi-massive sulphide development. The intersection confirms that the Mirado Fault Zone is mineralized and may represent a significant structural control on gold deposition across the broader project area. KLDC believes the combination of strong gold grades, intense alteration, and structural continuity within the fault zone highlights the potential for the Mirado Fault to host additional mineralized shoots both laterally and at depth, representing an important future exploration target within the evolving Mirado geological model.Figure 4 - Gold distribution in KLM26-005 and KLM26-006To view an enhanced version of this graphic, please visit:

NewsfileToronto, Ontario--(Newsfile Corp. - May 4, 2026) - Kirkland Lake Discoveries Corp. (TSXV: KLDC) (OTCQB: KLKLF) ("KLDC" or the "Company") is pleased to announce assay results from its ongoing 2026 diamond drilling program at the past-producing Mirado property, located 20 km southeast of Kirkland Lake, Ontario.Highlights:KLM26-0030.87 g/t Au over 27 m from 13 m to 40 m0.26 g/t Au over 16 m from 81.5 m to 97.5 m0.25 g/t Au over 32.9 m from 112.6 m to 145.5 mKLM26-00439.35 g/t Au over 16.4 m from 53.6 m to 70 m, including:106.9 g/t Au over 6.0 m from 55 mand including 1,670 g/t Au over 0.38 m from 58.62 m2.22 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 from 91.3 m40-m step out south from hole KLM26-002High-grade mineralizationSix holes pending using Chrysos PhotonAssay™ for expedited resultsResults from drill hole KLM26-004, located approximately 40 metres 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 (see Figure 1). Drill hole KLM26-003, positioned between KLM26-001 and KLM26-002, returned 0.87 g/t Au over 27 m from 13 m, 0.26 g/t Au over 16 m from 81.5 m, and 0.25 g/t Au over 32.9 m from 112.6 m, further supporting continuity of the mineralized envelope along strike (see Table 1). The combination of the broad, continuous mineralization intersected in KLM26-002 (1.01 g/t Au over 121 m) and the higher-grade, visible gold-bearing intervals in KLM26-004 (see Figure 2 and Figure 3) highlights the role of structural controls, sulphide concentration, and quartz-carbonate veining in upgrading gold grades within the system.Chief Executive Officer, Stefan Sklepowicz, commented, "As we progress into new areas at Mirado, we are seeing the exact geological signatures we had hoped for, broad, continuous mineralization punctuated by high-grade intercepts. KLM26-004 clearly demonstrates the potential of this system. With six additional holes pending, we are eager to see how these results continue to define the scale of this project." Executive Chairman, Denis Laviolette, commented, "Historically, Mirado was interpreted as a series of discrete, stacked lenses. Our recent drilling, however, demonstrates that gold mineralization is far more continuous, with significant values bridging previously separated zones. Notably, we have identified localized high-grade gold (>1,600 g/t Au) within quartz-carbonate vein networks. While these high-grades impact composite intervals, we believe premature grade capping would misrepresent the deposit's true geological nature. It is now clear that gold is concentrated along structurally controlled networks within a large, continuous system, providing a scalable model to systematically vector toward high-grade shoots and expand the project's overall footprint."

https://images.newsfilecorp.com/files/5701/295712_4ac166f61437c8fb_002full.jpgMineralization Style and Geological ContextMineralization reported herein is associated with the South Zone and is hosted within intermediate volcanic units, characterized by quartz-carbonate stringer systems with 1-5% disseminated pyrite and strong local vein replacement (locally up to 90%). In drill hole KLM26-004, mineralization is developed within a medium grey-green, massive fragmental agglomerate, with a chlorite-dominant matrix and sericite-altered fragments. Quartz-carbonate stringers are locally irregular and strongly associated with elevated sulphide content and visible gold, including eight instances of visible gold observed on and adjacent to a quartz-carbonate stringer at approximately 58.86 m. Sulphide mineralization consists of fine-grained disseminated and fracture-filled pyrite (1-5%), locally increasing to semi-massive concentrations over short intervals.Alteration is dominated by pervasive chlorite-carbonate with localized sericite, silicification, and epidote, with minor chalcopyrite occurring in more strongly altered intervals. This mineralization style reflects a structurally controlled vein and stringer system developed within a broadly altered volcanic host, with gold preferentially concentrated along zones of enhanced permeability, including quartz-carbonate veining and associated sulphide enrichment.Lithology and Alteration Controls on MineralizationKirkland Lake Discoveries Corp. is advancing a refined understanding of the lithological and alteration controls on gold mineralization within the South Zone, where mineralization is hosted across multiple volcanic units and exhibits strong structural and lithological controls. Results to date highlight a clear relationship between host rock competency, structural preparation, and hydrothermal alteration in driving gold concentration.Agglomerates represent the principal host to high-grade mineralization, returning the highest grades and greatest frequency of elevated gold values, including the majority of samples exceeding 4 g/t Au. Intermediate and felsic crystal tuffs also return elevated average grades and are interpreted to represent key rheological contrasts where deformation and folding have enhanced permeability and focused gold-bearing fluids. Conversely, intermediate tuffs and lapilli tuffs define a broader, lower-grade mineralized envelope, while mafic units remain comparatively under-mineralized.Across all lithologies, metasomatism is the dominant alteration process, with silica, chlorite, and quartz-carbonate assemblages showing the strongest association with elevated gold values. Higher-grade mineralization consistently coincides with zones where these alteration assemblages overprint structurally prepared rocks.Table 2 summarizes gold distribution by lithology and associated alteration assemblages within the South Zone and highlights the strong correlation between gold mineralization, agglomerate and crystal tuff host rocks, and silica-chlorite-quartz-carbonate alteration systems.Table 2 - Gold Distribution by Lithology and Associated Alteration, South ZoneLithologyTotal assayed length mWeighted average Au g/tMax Au g/tSamples >=0.1 g/tSamples >=0.5 g/tSamples >=1.0 g/tSamples >=4.0 g/tGold-bearing top alterationAgglomerate320.10.721670.00208432610Metasomatism (40.0m); Silica (38.9m); Chlorite (21.6m); Sericite (15.1m); Epidote (10.1m); Qtz-Carb (5.8m)Intermediate Tuff154.30.3511.8611025135Metasomatism (37.4m); Sericite (34.1m)Intermediate Lapilli Tuff262.50.1815.08911853Metasomatism (21.7m); Qtz-Carb (21.0m); Chlorite (11.8m); Silica (7.6m); Sericite (1.1m)Intermediate Crystal Tuff71.31.4584.366420102Metasomatism (39.2m); Silica (3.2m)Mafic Crystal Tuff42.20.180.7528800Metasomatism (9.7m); Silica (4.5m); Chlorite (3.2m); Qtz-Carb (2.7m)Felsic Crystal Tuff45.11.0647.39211052Metasomatism (14.1m); Qtz-Carb (1.9m) Figure 3 - Gold bearing zones in KLM26-003 and KLM26-004.

https://www.youtube.com/watch?v=auW_irzISIkData 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. This approach improves analytical precision and reduces the impact of coarse gold ("nugget effect") compared to traditional fire assay methods, while also enabling faster turnaround times.

Hamilton Ontario CanadaMulti-Element33MA-OESSparks, Nevada, USA Samples returning gold values above the 350 ppm 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 were conducted by qualified persons consistent with National Instrument 43-101 and industry best practices. Certified reference standards and blanks were 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 3.0 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.Qualified PersonThe technical information contained in this news release has been reviewed and approved by Benjamin Cleland, P.Geo., Vice-President Exploration, who is a Qualified Person as defined by National Instrument 43-101 - Standards of Disclosure for Mineral Projects.About Kirkland Lake Discoveries Corp.Kirkland Lake Discoveries Corp.
