Kirkland Lake Gold Reports Additional High Grade Intercepts and Identifies New Mineralization at Macassa From Underground Drilling on the South Mine Complex

TORONTO, ONTARIO--(Marketwired - Nov 7, 2016) - Kirkland Lake Gold Inc., ("Kirkland Lake Gold" or the "Company") (TSX:KLG), is pleased to report new high grade drill intercepts from underground exploration drilling on the South Mine Complex ("SMC") at the Macassa Mine Complex, in Kirkland Lake, Ontario.

The drilling program infilled gaps in drill hole coverage between inferred resource blocks and identified new mineralization associated with the easterly strike extension of the SMC within the HM Claim, located approximately 2,000 feet (610 metres) southeast of the #2 shaft at the Macassa Mine Complex.

Underground Drilling Highlights:

• 651.8 g/t Au (93.6 g/t cut) over 3.8 metres, including 2,846.1 g/t Au over 0.5 metres, in hole 53-2921
• 40.1 g/t Au over 3.0 metres in hole 53-2967
• 97.7 g/t Au (70.2 g/t cut) over 1.6 metres, including 263.3 g/t Au over 0.3 metres, in hole 53-3065
• 102.5 g/t Au (26.7 g/t cut) over 3.2 metres, including 923.3 g/t Au over 0.3 metres, in hole 53-3098
• 100.5 g/t Au (68.6 g/t cut) over 1.6 metres, including 261.6 g/t over 0.3 metres, in hole 53-3099

Notes: All intercepts are core lengths. High grade assays are cut to 246.9 g/t or 120.0 g/t depending on the zone. (see tables below for more information).

Mr. Tony Makuch, President and Chief Executive Officer of the Company commented, "We are encouraged by these new drill results. Not only does this confirm that the SMC mineralization continues to extend to the east, but this may provide us with the opportunity to further expand the known resource and potentially increase the level of confidence of the mineral resources, as we continue our current underground diamond drill program in the area. We are in the process of extending the exploration drift further to the east, closing the almost 1,500 meter gap between the current known extent of the SMC mineralization, and the regional surface holes that encountered previously reported SMC style mineralization. We look forward to releasing additional results as they become available."

Underground Drilling Program Continues to Grow the SMC Further to the East

This program concentrated on both infilling gaps in drill hole coverage and also expanding the SMC further to the east within the HM Claim by testing a zone which was initially identified by drill hole 53-2414 which returned 21.6 g/t Au over a core length of 0.9 metres (see press release dated March 3, 2014). Follow up drilling on this zone was conducted where results in drill hole 53-2705, returned 13.5 g/t Au over a core length of 1.5 metres, and drill hole 53-2886 which returned 383.3 g/t over a core length of 2.6 metres (see press release dated June 9, 2014). This new zone is located in the footwall, north of the New South Zone (which is part of the SMC), and has been identified as Footwall Zone 2 ("FWZ-2") for resource modelling purposes.

The Company has since completed 24 additional drill holes which has expanded and better defined this zone of mineralization. Based on the additional drilling, the FWZ-2 strikes north 20 degrees east with a shallow (5 degree) east dip. It has been defined over a strike length of 130 metres and located between the -5769 and -5850 elevations (approximately 21 metres below the NSZ). It is open up dip and is currently being tested with additional step out drilling. The Company recently extended the 5300' Level exploration drift an additional 190 metres to the east, and excavated a drill station which will be used to explore for SMC related mineralization to the east.

QA/QC Controls

The Company has implemented a quality assurance and control (QA/QC) program to ensure sampling and analysis of all exploration work is conducted in accordance with best practices. The drill core is sawn in half with one half of the core samples shipped to Swastika Laboratories in Swastika, Ontario. The other half of the core is retained for future assay verification. Other QA/QC includes the insertion of certified reference standards, blanks and the regular re-assaying of pulps and rejects at alternate certified labs. Gold analysis is conducted by fire assay using atomic absorption or gravimetric finish. The laboratory re-assays at least 10% of all samples and additional checks may be run on anomalous values.

Qualified Person

The Company's exploration programs are under the supervision of Doug Cater, P.Geo., Vice President of Exploration. Mr. Cater is the 'qualified person' for the purpose of National Instrument 43-101, Standards of Disclosure for Mineral Projects, of the Canadian Securities Administrators, and has reviewed and approved this news release.
