THIS NEWS RELEASE IS INTENDED FOR DISTRIBUTION IN CANADA ONLY AND IS NOT INTENDED FOR DISTRIBUTION TO UNITED STATES NEWSWIRE SERVICES OR DISSEMINATION IN THE UNITED STATES

Kirkland Lake Gold Ltd. ("Kirkland Lake Gold" or the " Company ") (TSX:KL) (NYSE:KL) (ASX:KLA) today announced it has closed its previously announced sale of 18,450,000 common shares (each, a "Share") of Novo Resources Corp. ("Novo") and 9,225,000 warrants of Kirkland Lake Gold (each, a "Warrant") to purchase Shares to qualified purchasers for gross proceeds to Kirkland Lake Gold in the amount of $45,202,500 (the "Sale Transaction"). The Shares and Warrants were sold through Stifel GMP and Clarus Securities Inc.

Each Warrant entitles the holder thereof to acquire one additional Share owned by Kirkland Lake Gold at an exercise price of $2.80 for a term of 12 months expiring on December 3, 2021. In the event all Warrants are exercised, an additional $25,830,000 will be paid to Kirkland Lake Gold, for total gross proceeds of $71,032,500.

The securities sold and to be sold under the Sale Transaction have not been, and will not be, registered under the United States Securities Act of 1933, as amended (the "U.S. Securities Act"), or any state securities laws, and accordingly, may not be offered or sold within the United States or to or for the account or benefit of a U.S. person (as defined in Regulation S under the U.S. Securities Act) or a person in the United States, except in compliance with the registration requirements of the U.S. Securities Act and applicable state securities requirements or pursuant to exemptions therefrom. This news release does not constitute an offer to sell or a solicitation of an offer to buy any of the securities in the United States.

Early Warning Disclosure

Kirkland Lake Gold disposed of an aggregate of 18,450,000 Shares pursuant to the Sale Transaction at an attributed value of $2.45 per Share (attributing the full unit value of $2.45 to the Share component of the unit and nil value to the Warrant component of the unit) for aggregate gross proceeds of $45,202,500. Prior to completion of the Sale Transaction, Kirkland Lake Gold held 27,675,168 Shares, representing approximately 12.1% of the outstanding Shares on a non-diluted basis. Upon completion of the Sale Transaction, Kirkland Lake Gold owns 9,225,168 Shares, representing approximately 4% of the outstanding Shares on a non-diluted basis, representing a decrease in Kirkland Lake Gold's shareholdings in Novo of approximately 7.9%.

In the event the Warrants are exercised in full, Kirkland Lake Gold would dispose of an additional 9,225,000 Shares at a price of $2.80 per Share for additional gross proceeds in the amount of $25,830,000. This further disposition would result in an additional decrease in Kirkland Lake Gold's shareholdings in Novo, following which Kirkland Lake Gold would hold 168 Shares, representing less than 1% of the outstanding Shares on a non-diluted basis.

The disposition of Shares provides an immediate source of capital for the business of Kirkland Lake Gold.  While Kirkland Lake Gold currently has no immediate plans or intentions with respect to the Shares, depending on market conditions, general economic and industry conditions, trading prices of the Shares, Novo's business, financial condition and prospects and/or other relevant factors including Kirkland Lake Gold's financial position and liquidity, Kirkland Lake Gold may develop such plans or intentions in the future and, at such time, may from time to time acquire additional securities, dispose of some or all of the existing or additional securities or may continue to hold securities of Novo.

Kirkland Lake Gold will file an early warning report under National Instrument 62-103 in connection with the closing of the Sale Transaction.  A copy of the early warning report filed by Kirkland Lake Gold will be available under Novo's profile on SEDAR at www.sedar.com or by contacting Jennifer Wagner, Senior Vice President, Corporate Affairs, Legal Counsel at 647-361-0198. Kirkland Lake Gold's head office is located at 200 Bay Street, Royal Bank Plaza, Suite 2800, Toronto, Ontario M5J 2J1 and Novo's head office is located at 880-580 Hornby Street, Vancouver, British Columbia V6C 3B6.

As Kirkland Lake Gold will have decreased its security holdings in Novo below 10%, following the above-noted early warning report filing, it will no longer be required to report under the early warning requirements of National Instrument 62-104 – Take-Over Bids and Issuer Bids , unless its security holdings in Novo increases to 10% or more in the future.
