Kirkland Lake Gold Drilling at the South Mine Complex Intersects 386.7 Grams Per Tonne (Uncut) Over a True Width of 7.5 Meters on the South Claims

TORONTO, ONTARIO--(Marketwired - Nov. 12, 2015) - Kirkland Lake Gold Inc. (TSX:KGI) ("Kirkland Lake Gold" or the "Company"), an operating and exploration gold company, provides an update on the underground exploration drilling program on the South Mine Complex ("SMC") at the Company's Macassa Mine Complex, and in particular on the South Claims (formerly a part of the Queenston Mining Joint Venture property).

The South Claims are located approximately 800 metres south of the #2 shaft at the Macassa Mine Complex, and lie immediately southwest of the HM claim, and hosts a portion of the SMC. Exploration results on the HM claim were recently reported by the Company on October 20^th, 2015. This eighteen-hole (6,140 metres or 20,145 feet) drilling program is a continuation of the program detailed in the Company's press release dated January 20^th, 2015. This program concentrated on expanding the SMC by testing the New South Zone ("NSZ") and intersected both new and previously identified hanging wall ("HWZ") and footwall zones ("FWZ") to the NSZ.

Highlights:

• NSZ intersected in drill hole 53-2891B returned 386.7 grams per tonne ("g/t") uncut, (73.4 g/t cut) or 11.28 ounces per ton ("opt") uncut (2.14 oz/t cut) over a true width of 7.5 metres (24.6 feet). Intersected at the -5653 foot elevation (1,723 metres below surface).
  • Drill hole 53-2891B returned several high grade intervals including 5,678.8 g/t or (165.63 opt) over a true width of 0.3 metres (1.0 feet), 396.7 g/t (11.57 opt) over a true width of 0.6 metres (2.0 feet) and 1,845.6 g/t (53.83 opt) over a true width of 0.4 metres (1.3 feet). The NSZ remains open to the west and down-dip from this intersection. Drill hole 53-2694A, located 19.8 meters east of 53-2891B returned 25.7 g/t (0.75 opt) over a true width of 3.2 metres 10.6 feet). A previously identified FWZ was intersected in this drill hole and returned 243.4 g/t uncut or 120 g/t cut (7.10 opt uncut or 3.5 opt cut) over a true width of 0.2 metres (0.8 feet).
• New and previously identified FWZ and HWZ intersected.
  • Drill hole 53-2780 intersected two new hanging wall veins which returned 26.4 g/t (0.77 opt) over a core length of 1.5 metres (4.9 feet), and 39.4 g/t (1.15 opt) over a core length of 0.7 meters (2.3 feet). In addition, this drill hole intersected a previously identified footwall vein which returned 556.8 g/t or 120 g/t cut (16.24 opt uncut or 3.5 opt cut) over a true width of 0.2 meters (0.6 feet).

Notes: Higher grade assays are cut to 246.9 g/t (7.20 opt) or 120.0 g/t (3.50 opt), depending on the zone (see tables below for more information).

Mr. George Ogilvie, Chief Executive Officer of the Company commented, "The SMC remains an important zone for the Company and these results released today on the South Claims combined with the previously released results from the HM claim are encouraging for the future delineation and expansion of this zone. Drilling continues to intersect high grade mineralization further expanding the zone. We will continue to spend approximately 68% of our exploration efforts on the SMC drilling in 2016."

SMC Underground Drilling on the South Claims

Of the eighteen drill holes testing the NSZ, nine, or 50% of the holes intersected sufficient grade intervals for which a mineral resource may be calculated. Eleven of the eighteen holes returned significant intersections on either the NSZ or SMC related HWZ or FWZ. Seven of the eighteen holes returned insufficient grade intervals to delineate a mineral resource.

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 the best possible 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 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 results of the Company's underground diamond drilling program have been reviewed, verified (including sampling, analytical and test data) and compiled by the Company's geological staff under the supervision of Mr. Stewart Carmichael, P.Geo., Manager of Exploration. Mr. Carmichael 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.
