Toronto, Ontario--(Newsfile Corp. - July 9, 2025) - Kirkland Lake Discoveries (TSXV: KLDC) ("KLDC" or the "Company") is pleased to announce that it has received drill permits for its recently acquired Winnie Lake project, located in the western portion of its Kirkland Lake land package in Ontario's Abitibi Greenstone Belt. The Company also provides an update on exploration work completed in May and June, which has resulted in new mineral discoveries and meaningful advancements in geological understanding.
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.
Exploration Highlights
High-Grade Polymetallic Grab Sample at Winnie Showing
A grab sample collected near the historical Winnie shaft (Figure 1) returned:
- 1.60 g/t gold (Au), 28.20 g/t silver (Ag), 5.70% copper (Cu), 5.30% zinc (Zn), 1.65 g/t tellurium (Te)
The sample was taken from massive sulphide mineralization strongly associated with massive magnetite. This confirms the presence of high-grade polymetallic mineralization. To further assess the continuity of this magnetic feature under overburden, a high-resolution drone magnetic survey was completed in June.
New Discovery West of the Winnie Shaft
Field prospecting led to the discovery of a newly exposed, intensely quartz-veined intrusive outcrop approximately 150 metres west of the historical shaft. Channel sampling was completed after clearing, with the outcrop displaying:
- Visible malachite, chalcopyrite, and trace pyrite
- Strong potassic and hematite alteration
These characteristics are indicative of a magmatic-hydrothermal system, possibly representing an intrusion-related Cu-Au system or early-stage IOCG-style mineralization. The alteration style (potassic enrichment and hematite staining) is commonly associated with large, high-temperature hydrothermal systems sourced from or centered around intrusive bodies.
This newly identified zone lies just west of the historical workings, suggesting prior operators may have only tested a limited portion of the mineralized system. If confirmed by assays and drilling, this could represent a significant new mineralized body with scale potential.
Intrusion-Hosted Geochemical Signature
A sample collected directly from a quartz vein within the intrusion returned:
- 1,235 g/t bismuth (Bi), 1.56 g/t Te, 10.30 g/t molybdenum (Mo), 0.13% Cu, 12.75 g/t Ag, 0.03 g/t Au
This trace element suite, particularly the elevated Bi-Te-Mo values, is geochemically characteristic of Intrusion-Related Gold Systems (IRGS). These systems are known for:
- Broad alteration halos
- Large-scale, bulk-tonnage gold potential
- Association with reduced, fertile intrusions
The presence of these elements strengthens the interpretation that the Winnie intrusion is a mineralizing source, not barren, and may host a zoned mineralized system with both high-grade and disseminated potential.
Analogous Systems in the Region:
Notable intrusion-hosted deposits in the Abitibi include:
- Young-Davidson Mine (Alamos Gold) – Au in syenite with potassic alteration
- Upper Beaver (Agnico Eagle) – Cu-Au system with Bi-Te-Mo signature and IOCG features
- LaRonde Complex (Agnico Eagle) – Though primarily classified as a VMS deposit, deeper zones exhibit Cu-Au-Bi-Te-Mo enrichment and magmatic-hydrothermal features, suggesting a hybrid or transitional system in parts of the Blake River Group
These analogues support KLDC's ongoing evaluation of the Winnie intrusion as a significant mineralized center.

This includes the high-grade sample near the Winnie shaft, the newly exposed quartz-veined intrusive outcrop ~150m to the west, and the broader geological and structural framework revealed by the survey. Zones of interest are highlighted and prioritized for drilling, with assay results from channel sampling pending.
Additional Program Milestones
Channel Sampling Completed
- 41 metres of channel sampling were completed across newly stripped and historical outcrops in the Winnie Lake area.
- 75 individual samples were submitted for assay. Results will be reported once received and interpreted.
Drone Magnetic Survey Completed
KLDC completed a high-resolution drone magnetic survey in June, resulting in several key findings:
- A previously unrecognized magnetic low within the intrusive body has been identified. This feature may represent a reduced and altered core, possibly associated with mineralization. Similar magnetic lows host mineralized zones at deposits such as Upper Beaver.
- Improved definition of the contact between mafic volcanics and the intrusion, outlining multiple untested kilometers of strike.
This refined geophysical model is being used to finalize drill hole targeting for KLDC's upcoming inaugural drill program at the Winnie intrusive.
Drill Permits Received
KLDC is pleased to report that it has received full drill permits for the Winnie Lake project. The Company plans to initiate its first-pass drill program this summer, targeting the newly defined geochemical, magnetic, and alteration zones.
"The start of our field season has delivered meaningful results and key breakthroughs," said Stefan Sklepowicz, CEO of Kirkland Lake Discoveries. "With high-grade copper-zinc values, a newly discovered mineralized zone, and a promising geochemical signature pointing to a deeper intrusion-related gold system, we're executing a focused and cost-effective program that is unlocking the potential of the Winnie Intrusion. With drill permits now in hand, we look forward to testing these compelling targets this summer."
Video Footage Available
Field footage of the newly discovered outcrop and channel sampling is available through the Company's YouTube channel, specifically KLDC Treasure Hunter's Episode 14: Boots in the Bush, Suits in the City.
