Kirkland Lake Gold is a high-grade, low-cost gold producer with two key assets, Fosterville in Australia and Macassa in Canada. In the first half of 2017, Kirkland Lake produced over 290,000 ounces of gold and is on track to meet its 2017 guidance of 570,000-590,000 ounces. Fosterville has seen significant increases in its underground mineral reserves and is expected to be a key value driver, with production guidance increased to 250,000-260,000 ounces at significantly lower costs. Macassa also provides high-grade, low-cost production from its long-life reserves and large resource base. Exploration continues to expand resources at both key assets.

June 2017 Mineral Reserves
1) CIM definitions (2014) were followed in the calculation of Mineral Reserves; 2) Mineral Reserves were estimated using a long-term gold price of US$1,200/oz (A$1,500/oz)
3) Cut-off grades varied from 2.0 g/t Au to 3.1 g/t Au, depending upon width, mining method and ground conditions; Dilution varies from 5 to 40 % and mining recovery ranging between 60 – 100% were applied to stopes
within the Mineral Reserve estimate; 4) Mineral Reserves estimates were prepared under the supervision of Ion Hann, FAusIMM; 5) Fosterville CIL Residues are stated as Proven contained ounces. Mill recoveries of 25% are
planned, based on operating performance; 6) Mineral Resources were estimated using cut-off grades 0.7 g/t Au for oxide and 1.0 g/t Au for sulfide mineralization to potentially open-pitable depths of approximately 100m,
below which a cut-off grade of 3.0 g/t Au was used; 7) Mineral Resource estimates were prepared under the supervision of Troy Fuller, MAIG; 8) Totals may not add exactly due to rounding 8

extraction, mill recovery.
Cut-off grades for Australian Assets from 0.4 g/t Au to 3.1 g/t Au, depending upon width, mining method and ground conditions; Dilution and mining recovery factors varied by property
Mineral Reserves estimates for the Canadian Assets were prepared under the supervision of P. Rocque, P. Eng.
Mineral Reserves estimates for the Fosterville property were prepared under the supervision of Ion Hann, FAusIMM.
Fosterville CIL Residues are stated as Proven contained ounces. Mill recovery of 25% are planned, based on operating performance.

Cautionary Note to U.S. Investors - Mineral Reserve and Resource Estimates
All resource and reserve estimates included in this news release or documents referenced 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.
