KL WEST PROJECT

KL West is a district-scale gold exploration project covering more than 21,000 hectares, in the underexplored Blake River Group of the Abitibi Greenstone Belt, immediately north of Agnico Eagle’s operating Macassa mine.

Current exploration is driven by a regional geochemical signature defining both intrusion-related gold (IRGS) and VMS systems. Work is focused on the Winnie Pluton, where large magmatic-hydrothermal systems have been identified with strong alteration, structural controls, and multi-element geochemical vectors. A 17-km contact corridor hosts numerous untested drill targets, including areas of IRGS and VMS overprinting that may enhance metal endowment.
 
Ongoing drilling is testing and confirming mineralization continuity at surface and at depth.

GEOLOGICAL OVERVIEW

The KL West project is hosted within the volcanic and intrusive rocks of the Blake River terrane in the Abitibi Greenstone Belt and is located immediately north of the Macassa Mine. Gold mineralization on the property is developed within a multi-phase magmatic-hydrothermal system and occurs across a diverse range of geological settings, including felsic volcanic sequences, volcaniclastic and sedimentary units, and intrusive complexes such as gabbro, syenite, and feldspar porphyry.

Gold is expressed as quartz vein systems and disseminated sulfides within altered host rocks, reflecting both structurally controlled and lithologically influenced styles. Sulfide assemblages are dominated by pyrite with variable chalcopyrite and sphalerite, and locally include tellurides and molybdenite. Alteration is characterized by silicification, sericite, and locally potassic assemblages, indicating evolving hydrothermal conditions and fluid-rock interaction across multiple mineralizing phases.

Mineralization is spatially associated with lithological contacts, intrusive margins, and zones of deformation, including shear zones and fault networks that act as conduits for fluid flow. A large-scale, coherent soil geochemical anomaly extends across portions of the property, reflecting the broader footprint of the mineralized system. Active drilling is ongoing within intrusive-hosted settings, where magmatic-hydrothermal alteration and structural complexity coincide, supporting continuity of mineralization at surface and at depth.

 

At the regional scale, the project lies within a continuous mineralized corridor influenced by major structural features, including the broader Kirkland Lake structural system. The scale, diversity, and continuity of favorable geological elements support strong potential for additional mineralized zones along strike, at depth, and within parallel or structurally offset corridors. These systems are widely recognized for their high-grade potential and depth continuity, supporting the project’s prospectivity within the Abitibi.
