identified by the words “may”, “would”, “could”, “should”, “will”, “intend”, “plan”, “anticipate”, “believe”, “estimate”, “expect” or similar expressions and include information
regarding: (i) the amount of future production over any period; (ii) assumptions relating to revenues, operating cash flow and other revenue metrics set out in the Company's
disclosure materials; and (iii) future exploration plans (iv) the temporary suspension of operations at the Cosmo Mine and the anticipated effects thereof .
Investors are cautioned that forward-looking information is not based on historical facts but instead reflect KL Gold’s management’s expectations, estimates or projections
concerning future results or events based on the opinions, assumptions and estimates of management considered reasonable at the date the statements are made. Although
Kirkland Lake Gold believes that the expectations reflected in such forward-looking information are reasonable, such information involves risks and uncertainties, and undue
reliance should not be placed on such information, as unknown or unpredictable factors could have material adverse effects on future results, performance or achievements of the
combined company. Among the key factors that could cause actual results to differ materially from those projected in the forward-looking information are the following: the ability
of Kirkland Lake Gold to successfully integrate the operations and employees of its Canadian and Australian operations, and realize synergies and cost savings, and to the extent,
anticipated; the potential impact on exploration activities; the potential impact on relationships, including with regulatory bodies, employees, suppliers, customers and
competitors; the re-rating potential following the consummation of the merger; changes in general economic, business and political conditions, including changes in the financial
markets; changes in applicable laws; and compliance with extensive government regulation. This forward-looking information may be affected by risks and uncertainties in the
business of Kirkland Lake Gold and market conditions. This information is qualified in its entirety by cautionary statements and risk factor disclosure contained in filings made by
Kirkland Lake Gold , including Kirkland Lake Gold’s annual information form, financial statements and related MD&A for the first quarter ended March 31, 2017 and their interim
financial reports and related MD&A for the period ended March 31, 2017 filed with the securities regulatory authorities in certain provinces of Canada and available at
www.sedar.com.
Should one or more of these risks or uncertainties materialize, or should assumptions underlying the forward-looking information prove incorrect, actual results may vary
materially from those described herein as intended, planned, anticipated, believed, estimated or expected. Although Kirkland Lake Gold has attempted to identify important risks,
uncertainties and factors which could cause actual results to differ materially, there may be others that cause results not to be as anticipated, estimated or intended. Kirkland Lake
Gold does not intend, and do not assume any obligation, to update this forward-looking information except as otherwise required by applicable law.
All dollar amounts in this presentation are expressed in U.S. Dollars unless otherwise noted.

Notes
CIM definitions (2014) were followed in the calculation of Mineral Reserves
Mineral Reserves were estimated using a long-term gold price of US$1,200/oz (C$1,500/oz; A$1,500/oz)
Cut-off grades for Canadian Assets were calculated for each stope, including the costs of: mining, milling, General and Administration, royalties and capital expenditures and other modifying factors (e.g. dilution, mining
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.
Mineral Reserves estimates for the Northern Territory property were prepared under the supervision of Jason Keily, FAusIMM (CP).
Mineral Reserves estimates for the Stawell property were prepared under the supervision of Ian Holland, FAusIMM.

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.
