KIRKLAND LAKE DISCOVERIES ANNOUNCES DRILL PERMIT APPROVAL AND COMPLETION OF HIGH-RESOLUTION GEOPHYSICAL SURVEY

Kirkland Lake Discoveries Corp. has noted that the drilling permit for the Goodfish Kirana property has been approved by the Ministry of Northern Development, Mines, Natural Resources and Forestry (NDMNRF), effective June 6, 2023, for three years. In addition, the high-resolution airborne magnetic survey recently undertaken at the Lucky Strike property has been completed. Data compilation and processing of the survey data is currently under way.

The 2,105-line-kilometre survey across the Lucky Strike property was completed in a timely and efficient manner by ALS GoldSpot Discoveries Ltd.'s geophysical services division from June 5 to June 14, 2023. The survey parameters included a flight-line azimuth of zero degree/180 degrees and flight-line spacing of 100 metres, with infill lines completed in selected areas at 50 m spacing. Tie lines at 500 m spacing had an azimuth of 90 degrees/270 degrees.

This high-resolution survey utilized ALS GoldSpot's M-PASS system, a proprietary platform that has been designed to collect co-referenced triaxial magnetic, very low frequency (VLF) electromagnetic multiband radiometric and lidar (light detection and ranging) data sets specifically designed to support exploration efforts and artificial intelligence (AI) analysis.

Shawn Hood, general manager of ALS GoldSpot, commented: "This has been a large and detailed survey for Kirkland Lake Discoveries to collect data layers which will underpin future AI-enhanced exploration. Now that this milestone is complete, these newly acquired data sets can be processed in multiple ways to support the Lucky Strike project. We look forward to how this data will guide the upcoming exploration plans of Kirkland Lake Discoveries."

The raw geophysical data sets collected by this survey are currently being processed and results are anticipated in early July. Once the data sets are received, the company will undertake a geophysical and structural interpretation. This interpretation will be incorporated with the current geological understanding and known mineral showings of the Lucky Strike property using ALS GoldSpot's proprietary AI algorithms. The results of this data analysis will help guide future exploration plans, including follow-up field and drilling activities.

"We are excited to receive the results and interpretation of this airborne survey, which will provide the foundation to our geological and structural understanding of this most recently acquired portion of our district-scale land package. Structure is key to the orogenic gold deposit model, not only in the Kirkland Lake gold camp, but throughout the metal-endowed Abitibi greenstone belt. The airborne survey data will be married with known historical mineralized showings and structures, and follow-up work will include the ground-truthing and drilling of known mineralized trends. All of this work, along with the exploration drilling on our project, continues to advance our efforts towards making a discovery in the gold-rich Kirkland Lake camp," stated Daniele Spethmann, chief executive officer of Kirkland Lake Discoveries.

About Kirkland Lake Discoveries Corp.

Kirkland Lake is a TSX Venture Exchange-listed company that has consolidated a district-scale and prospective land package in the Kirkland Lake gold camp in Ontario, Canada. The properties are hosted in the Abitibi greenstone belt, one of the world's best-endowed greenstone belts, with over 200 million ounces of gold produced to date. The properties are host to regional and property-scale mineralized structures that are considered second-order structures off the Larder Lake Cadillac deformation zone (LLCDZ), the regional structure in the belt known to be spatially associated with the gold mines hosted in the camp.

The properties assembled include the 100-per-cent-owned Lucky Strike property, Goodfish-Kirana, the Arnold property, and the optioned KL West (KLW) and KL Central (KLC) properties. The Kirkland Lake Discoveries land position comprises approximately 38,000 hectares, over 1,338 claims and 29 patented claims, and ranks the company as the largest landholder in the Kirkland Lake region.
