KL SOUTH PROJECT
MIRADO

KL South is located approximately 20km south of Kirkland Lake and hosts a near surface historical inferred resource of 442,000 oz of gold at 1.29 g/t at the Mirado Property.

 

2026 drilling at Mirado validated historical mineralization and significantly expanded the bounds of the resource shell laterally and at depth. With the recent discovery of Mirado West, the mineralized footprint now extends over 1,300m. Systematic drilling to expand and further understand the system will continue.

KL South hosts several highly prospective, untested targets beyond Mirado that represent district-scale potential within a proven gold district.

GEOLOGICAL OVERVIEW

The KL South project is hosted within a volcanic sequence of felsic flows, tuffs, and intermediate volcaniclastic rocks in the Abitibi Greenstone Belt.
 
At Mirado, Gold mineralization is structurally controlled and developed within a multi-phase hydrothermal system, exhibiting both stratigraphically influenced and discordant mineralization styles.

Mineralization occurs as quartz-carbonate vein systems and as disseminated sulfides within altered host rocks. Sulfide assemblages are dominated by pyrite with subordinate sphalerite and chalcopyrite, with gold occurring as inclusions within sulfides or associated with vein systems. Alteration is characterized by quartz-sericite-pyrite assemblages in stratiform zones and quartz-chlorite ± chalcopyrite in later extensional vein systems.

Gold mineralization is spatially associated with felsic volcanic units and is locally enhanced by structural complexity, including folding, thrusting, and late extensional faulting, which create favorable sites for fluid flow and gold deposition.

At the regional scale, the system lies within a continuous volcanic belt where favorable stratigraphy, structural corridors, and hydrothermal alteration are developed over broad areas. The property is bounded by major regional structures to the west and east, including the Catherine and Lincoln-Nipissing faults, which form part of a broader structural framework associated with gold mineralization. Multiple mineralized centres across the property demonstrate a broad and continuous mineralized system, spatially linked by major structural features and locally associated with intrusive phases. These relationships reflect a long-lived hydrothermal system with potential for additional mineralization along strike, at depth, and within parallel or offset structural corridors.
