Kirkland Lake Discoveries Consolidates Key

Ground Around Winnie Lake Pluton

Toronto, Ontario--(Newsfile Corp. - April 29, 2025) -

Kirkland Lake Discoveries (TSXV: KLDC)

("KLDC" or the "Company")

is pleased to announce that it has entered into a Mining Option

Agreement with

Val-d'Or Mining Corporation

(TSXV: VZZ)

to acquire a 100% interest in the

Winnie

Lake

and

Amikougami

properties, located near Kirkland Lake, Ontario.

Under the terms of the agreement, KLDC has been granted an exclusive four-year option by Val-d'Or

Mining Corporation to acquire the properties, which are strategically located within the Abitibi

Greenstone Belt and prospective for volcanogenic massive sulphide (VMS) and intrusion-related

mineralization (Image 1).

In addition, the Company has entered into Mining Claim Purchase Agreements with Charles Gryba (

the

"Gryba Transaction"

) and Sudeep Mathew (

the "Mathew Transaction"

) to acquire additional claims

contiguous with the Company's KL West Property around the Winnie Lake Pluton.

"The acquisition of these properties enhances our strategic land position and gives us exciting targets

for 2025 and beyond," c

ommented Stefan Sklepowicz, Chief Executive Officer. "

The KL West property

holds tremendous potential for

gold-rich

critical mineral deposits, particularly of copper and zinc. We

look forward to this year's exploration programs to unlock the full potential surrounding the Winne

Lake Pluton and to discover additional mineralization."

Geological Setting

The Winnie Lake Property ("Winnie") is underlain by a folded sequence of Blake River Assemblage

(BRA) mafic to intermediate volcanics intruded by the synvolcanic

Winnie Lake Pluton

(~2,677 Ma).

The BRA is the youngest volcanic sequence in the Abitibi Greenstone Belt which hosts the

highest

concentration of VMS Cu-Zn deposits.

Approximately

50% of total VMS tonnage

and

90% of VMS-associated gold

in the Abitibi occur

within the BRA

1

. The Noranda camp, 60 km east of Winnie, includes

17 past-producing VMS mines

.

Subvolcanic intrusives in the Noranda camp are considered 'heat engines' for VMS formation-which

Winnie's geological setting parallels

2

.

Underpinning Winnie is the Shaft Zone, a gold-rich VMS system that has yielded significant drill results

including:

Pamorex Resources, 1989

:

TWL-89-01

1.93% Cu, 1.51% Zn, 0.786 g/t Au and 12.1 g/t Ag over 18.41 m (from 11.89 m)

2.44% Cu, 3.63% Zn, 1.376 g/t Au and 16.5 g/t Ag over 10.12 m (from 31.15 m)

within a broader intercept of 1.34% Cu, 1.53% Zn, 0.638 g/t Au, 9.5 g/t Ag over 47.12 m (from 11.89 m)

Surface grab samples historically returned up to

25% Cu, 13% Zn and 2.74 g/t Au.

Golden Valley, 2005:

GWL-05-04 (Shaft Zone)

1.5% Zn, 0.34% Cu, 8.15 g/t Ag over 9.32m (incl. 17.0% Zn over 0.32 m)

GWL-05-01 (1.4km West):

1.96% Zn and 4.73% Pb over 0.82 m

GWL-05-06 (300m SE)

1.82% Zn and 0.90 g/t Ag over 0.31m in epidote-altered mafic volcanics

There has been

no drilling at Winnie since 2005

. These mineralized zones remain

open along strike

and at depth

, along with several untested IP geophysical anomalies associated with oval 'bullseye'

magnetic highs (Image 2).

This magnetic signature continues into KLDC's KL West Property, representing a series of

high-

priority,

untested VMS targets

around the edge of the Winnie Lake Pluton.

With excellent road access, proximity to infrastructure, and a supportive mining jurisdiction, the Company

views the consolidated Winnie Lake area as a highly prospective setting for future critical and precious

metals discoveries.

Kirkland Lake Discoveries is currently planning a follow-up program that will include detailed geological

mapping and a spring/summer drill program to expand known zones and test new geophysical targets.

The Company's properties host regional and property-scale mineralized structures, considered second-

order structures off the Larder Lake Cadillac Deformation Zone (LLCDZ), a major regional structure

known for its spatial association with gold mines in the camp.

The properties assembled by the Company are grouped into two key areas: KL East, which includes the

Lucky Strike Property, Arnold Property, and KL Central, and KL West, which encompasses the

Goodfish-Kirana and the KL West Properties. KLDC's land position spans approximately 38,000 ha

over 1,338 claims and 29 patented claims, making the Company the largest landholder in the Kirkland

Lake region.​
