KL Kirkland Lake Gold Ltd

Kirkland Lake Gold Ltd. (“Kirkland Lake Gold” or the “Company”) (TSX:KL) (NYSE:KL) (ASX:KLA) today reported new drill results from 19 holes (9,522 m) of underground exploration drilling as well as 15 holes (29,085 m) of previously drilled (not reported) and re-interpreted holes from the Macassa Mine in Kirkland Lake, Ontario.

All of the new holes being reported were collared within two platforms located on the east portion of the 5300 Level, with 18 of the 19 new holes (8,760 m) being focused on confirmation and extension of the South Mine Complex (“SMC”) to the east (Figure 1). Results from the drilling included 43.1 gpt over 2.1m from hole 53-4016, 31.0 gpt over 2.3m from hole 53-4052 and 16.4 gpt over 2.1 m from hole 53-4088 which define a minimum 75 m extension of the SMC complex east of the current resource as well as 19.3 gpt over 4.2m from hole 53-4086 located 25m to the south.

One of the new holes (762 m) was designed to test the Main Break below the Kirkland Minerals shaft near the east limit of previous drilling. The hole (53-4052) was highly successful, intersecting 141.1 gpt over 2.4 m and 9.7 gpt over 2.0 m near the 6,850 Level, 300 m below the deepest level off the Kirkland Minerals shaft and 50 m east of previous drilling (Figures 2 and 3). Very importantly, the high-grade intersection is located within 650 m of the Company’s new #4 Shaft location (currently under development) and is believed to be part of a newly-identified corridor of high-grade mineralization 700 m long and 300 m high along the Main Break. The new corridor has been identified based on the results of new drilling as well as the interpretation of previously drilled but not reported holes along the Main Break on the Kirkland Minerals property, which is wholly owned by Kirkland Lake Gold.  The corridor is located below the 5,850 Levels and extends between the new #4 Shaft location and hole 53-4052. Additional key intercepts from the results being announced today include: 27.7 gpt over 2.1 m from AB17-07W3, 19.7 gpt over 2.0 m from hole AB15-130 and 18.5 gpt over 2.4 m from hole 53-3350. The corridor remains open along strike and to depth. A new exploration drift being developed off the 5700 Level to provide access to the SMC East will be extended into the high-grade corridor in support of further exploration of this high-potential target area.

Tony Makuch, President and CEO of Kirkland Lake Gold, commented: “We are extremely encouraged by the exploration results being announced today, which include the continued expansion of the SMC as well as the identification of a large area of high-grade mineralization along the historic Main Break located in close proximity to the location of our new #4 Shaft (currently under development). We have a truly unique and very exciting opportunity at Macassa to add substantial new Mineral Resources and, ultimately, Mineral Reserves through the continued growth of the SMC, the identification of high-grade mineralization along the largely unexplored Amalgamated Break, and also by drilling along the Main Break, which accounts for most of the 25 million ounces of historic production in the Kirkland Lake camp. While the resurgence of mining in Kirkland Lake over the last 10 – 15 years has been driven by the discovery and growth of the SMC, we have always recognized that the Main Break remains a highly-prospective target for additional exploration success and Mineral Resource growth. The fact that the new corridor of high-grade mineralization along the Main Break is located close to planned infrastructure adds significantly to the value creating potential of today’s results.”

Exploration drilling at Macassa has temporarily ceased as part of the Company’s COVID-19 health and safety protocols, which include the suspension of non-essential work. Upon the resumption of full operations at Macassa, exploration drilling will resume with up to six underground and surface drills.

Cautionary Note to U.S. Investors - Mineral Reserve and Resource Estimates

All references to Mineral Resources and Mineral Reserves included in this news release have been prepared in accordance with Canadian National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101") and the Canadian Institute of Mining, Metallurgy and Petroleum (the "CIM") - CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended (the "CIM Standards"). NI 43-101 is a rule developed by the Canadian Securities Administrators, which established standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. The terms "mineral reserve", "proven mineral reserve" and "probable mineral reserve" are Canadian mining terms as defined in accordance with NI 43-101 and the CIM Standards. These definitions differ materially from the definitions in SEC Industry Guide 7 ("SEC Industry Guide 7") under the United States Securities Act of 1933, as amended, and the Exchange Act.

In addition, the terms "Mineral Resource", "measured Mineral Resource", "indicated Mineral Resource" and "Inferred Mineral Resource" are defined in and required to be disclosed by NI 43-101 and the CIM Standards; however, these terms are not defined terms under SEC Industry Guide 7 and are normally not permitted to be used in reports and registration statements filed with the U.S. Securities and Exchange Commission (the "SEC"). Investors are cautioned not to assume that all or any part of mineral deposits in these categories will ever be converted into reserves. "Inferred Mineral Resources" have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an Inferred Mineral Resource will ever be upgraded to a higher category. Under Canadian rules, estimates of Inferred Mineral Resources may not form the basis of feasibility or pre-feasibility studies, except in very limited circumstances. Investors are cautioned not to assume that all or any part of a Mineral Resource exists, will ever be converted into a Mineral Reserve or is or will ever be economically or legally mineable or recovered.
