Kirkland Lake Discoveries Intersects 1.22 g/t Au over 69.5 m at New "Mirado West" Zone, Doubling Gold Footprint to over 1,300 m
Kirkland Lake Discoveries (KLKLF) reported initial 2026 drilling results from the newly renamed Mirado West zone at its KL South Project in Ontario.
Rhea-AI Summary
Kirkland Lake Discoveries (KLKLF) reported initial 2026 drilling results from the newly renamed Mirado West zone at its KL South Project in Ontario. Hole KLM26-037 intersected 1.22 g/t Au over 69.50 m from 33.00 m, including 5.67 g/t Au over 12.00 m, while KLM26-035 delivered multiple mineralized intervals, including 36.72 g/t Au over 1.01 m.
Mineralization and alteration match the Mirado South Zone and are interpreted as part of a contiguous system, extending known mineralization more than 600 m west and expanding the lateral mineralized footprint to over 1,300 m. Assays for 19 additional holes, including nine from Mirado North/South, four from Mirado West and six regional targets, are pending.

Toronto, Ontario--(Newsfile Corp. - September 2, 2026) - Kirkland Lake Discoveries Corp. (TSXV: KLDC) (OTCQB: KLKLF) ("KLDC" or the "Company") is pleased to report the first two holes from the regional testing around the Mirado deposit. MZ target holes KLM26-035 and KLM26-037 successfully intersected multiple broad intervals of gold mineralization and high-grade gold. Mineralization and alteration of these holes are consistent with the Mirado South Zone and are interpreted to be contiguous with the historical deposit. As such, the Company has renamed the MZ Zone to Mirado West. These holes are part of the ongoing summer 2026 drill program at KL South Project, 18 km south of Kirkland Lake, with 19 additional holes pending.
Highlights
- KLM26-037 - 1.22 g/t Au over 69.50 m from 33.00 m including 5.67 g/t Au over 12.00 m
- KLM26-035 - 0.35 g/t Au over 21.18 m from 19.50 m
and 0.65 g/t Au over 15.83 m from 65.20 m
and 0.34 g/t Au over 11.23 m from 95.50 m
and 36.72 g/t Au over 1.01 m from 174.50 m
and 0.89 g/t Au over 11.60 m from 222.40 m - Mineralization and alteration are consistent with the Mirado deposit, extending mineralization more than 600 m west and bringing the lateral mineralized footprint to over 1,300 m.
- 19 holes pending results
- Nine from Mirado North and South
- Four from Mirado West
- Six regional targets
"The discovery at Mirado West is a transformative milestone for Kirkland Lake Discoveries. Intercepting broad, near-surface mineralization validates our regional targeting and significantly scales up the project," stated Stefan Sklepowicz, Chief Executive Officer. "By extending our mineralized footprint to over 1,300 metres, we are demonstrating that Mirado is part of a much larger, contiguous gold system. With 19 holes still pending, including four more from this newly renamed Mirado West, we are eagerly anticipating the rest of the summer program's results."
"Today we've essentially doubled the east-west extent of the Mirado deposit, with perhaps the best hole we've drilled to date in and around Mirado," said Denis Laviolette, Executive Chairman. "This will have large implications in the future when we look to incorporate new drilling into a future resource update using both new expansion drilling and modern metals pricing and cutoff sensitivities."
Drill Program Discussion
Assay results from drill holes KLM26-035 and KLM26-037 represent a significant development in KLDC's geological understanding of the Mirado project. The current release includes two key holes targeting the newly renamed Mirado West (formerly the MZ target), located to the west of the main Mirado deposit (see Figures 1 and 2).

In Mirado West, hole KLM26-037 successfully intersected a broad, near-surface zone of mineralization, returning 1.22 g/t Au over 69.50 m starting from 33.00 m. This broad intercept includes a strong high-grade core of 5.67 g/t Au over 12.00 m. Hole KLM26-035, drilled from the same pad in the opposite direction, intersected multiple horizons of gold mineralization starting near surface and continuing at depth, showcasing the wide, continuous nature of the mineralized envelope in this new area. Notable intervals in KLM26-035 include 0.35 g/t Au over 21.18 m from 19.50 m, 0.65 g/t Au over 15.83 m from 65.17 m, and a deeper high-grade intercept of 36.72 g/t Au over 1.01 m from 174.49 m, see Table 1 and Figure 3.
These intercepts demonstrate that the mineralization and alteration styles observed at Mirado West are consistent with those of the Mirado South Zone and are interpreted to be part of a contiguous system. This successful step-out effectively extends the known mineralization more than 600 m to the west, immediately expanding the lateral mineralized footprint of the Mirado system to over 1,300 m wide.
Exploration momentum continues at the KL South Project. The Company is currently awaiting assay results from 19 additional holes from the ongoing summer 2026 drill program. These pending holes include:
- Nine holes from Mirado North and South
- Four holes from Mirado West
- Six holes from regional targets

Digital Resources
Stakeholders can explore KLDC's drilling through a publicly accessible interactive 3D model hosted by Mining Hub, which illustrates drill-hole data, mineralized intervals and interpreted target areas. The latest episode of KLDC's Treasure Hunters video series also provides an on-site update on drilling and exploration progress. VP Exploration Ben Cleland and the geological team discuss the latest results and the ongoing Mirado drill program.
Data Verification & Quality Assurance/Quality Control (QA/QC)
Gold analyses were completed on half-core NQ samples at Paragon Geochemical Laboratory (independent of KLDC) using Chrysos PhotonAssay technology. PhotonAssay is a non-destructive method that uses high-energy X-rays to measure gold in large approximately 500 g samples, reducing sampling variability associated with coarse gold mineralization and allowing the retained material to remain available for additional analysis.
Table 2 - Paragon Sample Preparation and Analytical Methods
| Analysis | Code | Location |
| Preparation | PREP-PKG | Timmins, Ontario, Canada |
| Photon and Fire Assay | PA-AU01, Au-SCR1K | Surrey, British Columbia | Hamilton, Ontario, Canada |
| Multi-Element | 33MA-OES | Sparks, Nevada, USA |
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. The sample is sieved at 110 microns, the coarse fraction is analyzed gravimetrically, and the fine fraction is analyzed in duplicate by AAS; the combined result provides a representative total gold value for samples that may contain 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 length-weighted average grades with a nominal 0.2 g/t Au cutoff. To reflect continuity within the broader mineralized system, up to 6.9 m of consecutive internal dilution below cutoff is included within selected composites. Reported assays are uncut and no top cut has been applied. All intervals are reported as downhole core lengths. True widths at Mirado are estimated at approximately
