Kirkland Lake Discoveries Announces Drill Permit Approval and Completion of High-Resolution Geophysical Survey

Kirkland Lake Discoveries Corp. (TSX-V - KLDC) ("KLDC or the "Company") is pleased to announce 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 underway.

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 ("ALS GoldSpot") Geophysical Services division from June 5 to 14, 2023. The survey parameters included a flight-line azimuth of 0º/180º and flight-line spacing of 100 m with infill lines complete in selected areas at 50 m spacing. Tie lines at 500 m spacing had an azimuth of 090º/270º (Figure 1).

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 multi-band radiometric, and LiDAR data sets specifically designed to support exploration efforts and Artificial Intelligence ("AI") analyses.

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 Danièle Spethmann, CEO of KLDC.

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