KL WEST

KLDC reports that ongoing drilling and integrated multi-element geochemical vectoring have significantly expanded the footprint of a large-scale mineralized system at its KL West Project.

KLDC has completed its previously announced acquisition of the Mirado Gold Project

KLDC provide a comprehensive geological and visual update on its ongoing, fully funded 25,000-m diamond drilling program at the KL West Property in the Kirkland Lake region of Ontario. With over 10,000 m now completed, the Company is reporting highly encouraging visual and observational results from the core logging facility. Recent drilling has consistently intersected hallmark geological indicators of a large-scale, intrusion-related gold and polymetallic system.

KLDC provides an update on its ongoing, fully funded 25,000-m diamond drilling program at its KL West Property in the Kirkland Lake region of Ontario.

With a strengthened technical team and a fully funded program, we are now positioned to drill with both confidence and purpose.

The program will target multiple high-priority zones identified through recent drilling, geophysical and geochemical work, including areas of coincident magnetic and conductive anomalies near key structural corridors.

The program intersected high-grade copper sulphides from surface and led to two new gold and critical mineral discoveries, confirming a new intrusive-related mineralizing system centered on the Winnie Pluton with a 17-km perimeter.

Toronto, ON – October 9 ,  2025 – Kirkland Lake Discoveries (TSX-V: KLDC, OTCID: KLKLF) (“KLDC” or the “Company”) is pleased to announce the successful completion of a 2,000 line-kilometre helicopter-borne magnetotelluric (MobileMT) survey over its KL West Project in Kirkland Lake, Ontario.   The Mobile MT survey, conducted by Expert Geophysics, commenced on September 23 rd and was completed on October 2 nd . MobileMT represents the most advanced generation of airborne AFMAG

KLDC is pleased to report that recent drilling at the KL West Property has expanded the mineralized system, with three additional holes intersecting semi-massive to massive sulphides. The results confirm the role of the Winnie Pluton as a key driver of mineralization and represent a significant advance in the Company’s intrusive-related exploration model across a district-scale land position.

The geological characteristics we’ve encountered in our very first drill hole have exceeded our expectations and fundamentally validate our interpretation of the Winnie system.

With strong surface results, supportive geology, and a well-developed model, we believe this program could be a catalyst for a new discovery.

The work builds on KLDC’s recent surface discoveries and geophysical targeting and supports multiple compelling targets for the Company’s upcoming inaugural drill program at Winnie Lake.

The KLDC field team has completed detailed prospecting, mapping, access planning, outcrop stripping, and channel sampling in preparation for the Company’s inaugural drill campaign at the Winnie intrusive. The focus is to test the potential for a copper-gold bearing intrusion-related system at the Winnie Lake showing and to evaluate newly identified geophysical and geochemical targets.

KLDC has entered into a Mining Option Agreement with Val-d’Or Mining Co. to acquire a 100% interest in the Winnie Lake and Amikougami properties, near Kirkland Lake, Ontario.

Drilling intersected intense alteration and fluid pathways that indicate the presence of a strong system.

The drill program will test the Hurricane Intrusive Zone, which was the subject of prospecting, mapping, and airborne magnetics in 2023.
