Kirkland Lake Discovery Company (TSXV: KLDC; OTC: Kalklf) has released assay results from its ongoing 2026 diamond exploration program at the former producing Mirado facility, located 20 km southeast of Kirkland Lake, northern Ontario.
Highlights – KLM26-002: 1.01 g/t gold over 121m from 11m to 132m, including 4.61g/t gold over 3.2m from 15.2m; 3.63 g/t Au over 12.8 meters from 69.7 metres, including 7.41 g/t Au over 4.8 meters from 74.2 metres; Step out of hole KLM26-001, 75 m long; A wide area of continuous mineralization. 732 m hole tests caused polarization (IP) anomalies; Eight holes hung with Chrysos PhotonAssay for fast results.
The second drill hole, targeting the southern area of Mirado, exited 75 meters southeast of KLM26-001 and confirms continuous mineralization of 1.01 g/t gold from 11.0 meters to 132.0 metres, including a high-grade break of 7.41 g/t gold over 4.8 meters from 74.2 metres. An additional eight holes have been completed with pending assays, representing a steady stream of results in the near term. Two holes test the northern zone and eight holes test the southern extent of the mineralization as well as the deep IP anomaly beneath the historic deposit. This hole follows KLM26-001/KLM26-001B, which intersected 103 meters of continuous mineralization, including 5.66 g/t over 18.7 metres.
Stefan Sklebowicz, CEO, commented: “We continue to see extensive mineralization within our second hole in the southern area of Merado. These results reinforce our geological model and demonstrate the robust nature of this system. Our team continues to execute this drilling program efficiently and we highly expect results from the remaining eight holes.”
Executive Chairman Denis Laviolette commented: “As the results continue to unfold, the assay chart tells the story here. This is a very large and prolific widespread gold system. This is rare at Abitibi, and with today’s metal prices, this represents a compelling restatement of the size of the deposit and the economic viability of this project.”
Mineralization style and geological context: The mineralization reported here is associated with the southern zone and is hosted within intermediate volcanic units, characterized by stringer systems of quartz carbonate with 1 percent to 5 percent widespread pyrite and strong local vein replacement (up to 90%). The alteration is dominated by widespread chlorite carbonates with localized sericite and siliciclastic, and minor chalcopyrite occurs in more strongly variable intervals, reflecting a structurally controlled vein and stringer system within a widely varying volcanic host.
The Mirado system includes two complementary patterns of gold mineralization. The southern zone consists of structurally controlled, high-grade quartz-carbonate-chlorite vein arrays within broader lower-grade envelopes, while the northern zone hosts stratigraphically controlled subconformal sulphide mineralization within felsic volcanics, which remains the focus of ongoing drilling.
The current results confirm the continuity of historically defined mineralization and show consistent downhole continuity, supporting the company’s advanced geological model and highlighting the strong potential for expansion along strike and at depth. In the Southern Zone, 121.0 meters of 1.01 g/t gold were recovered, including 3.2 meters of 4.61 g/t gold and 4.8 meters of 7.41 g/t gold in the Southern Zone.
Deep IP Anomaly Testing: The deepest hole drilled to date at the Mirado project, KLM26-007, reached a downhole depth of 732 meters and was designed to test a prominent low IP resistivity anomaly interpreted to extend below and below the South Zone mineralization.
The anomaly forms a coherent feature consistent with the expected subsidence of the southern region and may reflect increasing alteration, structural complexity and/or sulphide development at depth. Historical drilling has been largely limited to depths greater than approximately 150 metres, leaving this feature untested.
Ongoing drilling is designed to determine whether this anomaly represents continuation of subduction of the mineralized system or a broader alteration envelope associated with structural controls of the southern zone. The results of KLM26-007, along with subsequent deep drilling, will be crucial in determining the importance of this feature and its relationship to the overall mineralization system at Mirado.
Progress Update and Next Steps: Initial hole results from the 2026 drilling program, including KLM26-002, confirm the presence of broad areas of continuous gold mineralization within the South Zone and support lateral and vertical continuity of the system. Drilling has also begun to test the northern zone and deeper targets, including the IP anomaly beneath the southern zone, where historical drilling has been limited.
These results are integrated into a sophisticated 3D geological model, improving the company’s understanding of structural controls and mineralization trends.
Ongoing drilling will continue to focus on graded targeting along strike and at depth while systematically assessing subsidence potential in the southern area and testing geophysical targets, including the deep IP anomaly. Additional drilling will prioritize increased data density to support future resource modeling.
To further enhance targeting across the wider KL South properties, the company plans to create a mobile phonemetric tons Geophysical survey to provide area-wide coverage and improve structural and lithological interpretations across the entire project area.

Operating in a safe, mining-friendly region with a focused exploration program, Kirkland Lake Discoveries is developing Mirado into a well-defined, modern gold asset in the Abitibi Greenstone Belt.
The Kirkland Lake finds are grouped over a length of 420 km2 Exploration portfolio in the Kirkland Lake area of Ontario’s Abitibi greenstone belt, one of the most productive mining areas in the world. The company’s properties include major fault zones, geophysical anomalies, and volcanic-sedimentary contacts within the Blake River Group, a highly prospective assemblage known to contain massive deposits of gold and polymetallic sulphides.
