Kirkland Lake Gold Reports Exploration Results From Underground Drilling on the SMC and Initial Results Testing a New Zone on the '04 Break

TORONTO, ONTARIO--(Marketwired - May 24, 2016) - Kirkland Lake Gold Inc., ("Kirkland Lake Gold" or the "Company") (TSX:KGI), an intermediate gold producer with operations in Ontario, Canada, is pleased to report results from underground exploration drilling programs on the South Mine Complex ("SMC") and the '04 Break. The SMC drilling was focused on the South Claims (formerly a part of the Queenston Mining Joint Venture property) which 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 highly prospective portion of the SMC. Drilling from the 4250 foot level on the '04 Break mineralization commenced in May and is aimed at testing an area above the 3400 foot level, east of the Tegren fault to follow up on results from last year.

Underground Drilling Highlights:

Mr. George Ogilvie, Chief Executive Officer of the Company commented, "We are pleased to see that the SMC mineralization continues to extend giving us the opportunity to further expand the known resource and potentially increase the level of reserves as we continue to drill.

"The drilling on the '04 Break mineralization, although in its infancy, is very promising and we are pleased with these initial results. We will continue to drill this target area with a 1km strike length throughout the course of this year and into next year. Our hope is to define a zone of mineralization above the 3400L elevation ultimately with resources that could be brought into the mine plan sometime in 2017 or 2018. This would allow us to achieve an incremental increase in throughput from the Macassa Mine Complex."

Underground Drilling Program Continues To Grow The SMC Southeast Within The South Claims

This program concentrated on expanding the SMC by testing the New South Zone ("NSZ") as well as the previously identified hanging wall ("HWZ") and footwall zones ("FWZ") to the NSZ. Drilling continued to expand the NSZ with follow up drilling conducted to verify and expand around previously released drill results (see Company press release dated November 12, 2015) 53-2891B which returned 386.7 g/t (73.4 g/t cut) over a true width of 7.5 metres. Recently completed drill hole 53-3067 intersected the NSZ 14 metres to the west and up-dip of 53-2891B and returned 174.2 g/t (79.5 g/t cut) over 6.0 metres true width. It would appear that the wide intersections in these two drill holes represent the convergence of the NSZ and a footwall system further described in this release.

Additional step out drilling on the NSZ to the west included drill hole 53-2933 which returned 878.8 g/t (151.5 g/t cut) over a true width of 0.3 metres, drill hole 53-2934 which returned 42.9 g/t over a true width of 0.2 metres and drill hole 53-2936 which returned 55.2 g/t over 0.5 metres true width. These intersections have added 43 metres of strike length and joined two previous individual resource areas.

Both FWZ and HWZ to the NSZ continue to expand with a footwall zone to the NSZ which has a lobe that extends in the down dip component based on recent drilling. Drill hole 53-2932 returned 76.5 g/t (58.6 g/t cut) over a true width of 3.1 metres and drill hole 53-2933 returned 347.3 g/t (57.9 g/t cut) over a true width of 1.7 metres, both have extended the zone 104 metres down dip. This zone appears to converge with the NSZ further down dip as described previously.

The HWZ to the NSZ has now expanded into one continuous block with the addition of three new intersections. Drill hole 53-2933 returned 367.2 g/t (120.0 g/t cut) over a true width of 0.2 metres, drill hole 53-2934 returned 53.5 g/t (48.0 g/t cut) over a true width of 2.2 metres, and drill hole 53-2936 returned 29.1 g/t over a true width of 0.5 metres. These holes have added approximately 30.5 metres of strike length to this HWZ.

Testing The `04 Break East Of The Tegren Fault Now In Progress

The first two exploration holes drilled up dip from the new drill bay on the 4250 foot level tested the `04 Break east of the Tegren cross fault. The first hole, 42-1770, intersected the `04 Break 41 meters east from previously released drill hole 34-661 which assayed 76.5 g/t over 0.3 metres true width (see the Company press release dated February 23, 2015). Drill hole 42-1770 returned 27.4 g/t over 0.6 metres true width at the -3000 foot elevation. A new footwall zone was also intersected in drill hole 42-1770 at the -3053 foot elevation and returned 7.5 g/t over a core length of 1.2 metres (true width unknown at this time). The second completed drill hole from the -4250 level 42-1771, intersected the `04 Break at the -3173 elevation and returned 13.4 g/t over 0.2 metres true width. The `04 Break in drill holes 42-1770 and 42-1771 was strong, with associated quartz veining and visible gold observed in both drill holes.

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.
