Kirkland Lake Gold Infill Drilling Program Confirms Grade and Continuity of the South Mine Complex on the HM Claim

TORONTO, ONTARIO--(Marketwired - Jun 9, 2015) - Kirkland Lake Gold Inc. (TSX:KGI)(AIM:KGI), ("KL 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 HM claim (formerly a part of the Queenston Mining Joint Venture property).

The HM claim, located approximately 2,000 feet (610 metres) southeast of the #2 shaft at the Macassa Mine Complex, is an area that hosts the easterly strike of the SMC. The drilling program tested inferred resource blocks within a larger combined indicated and inferred resource area as well as along the fringe areas targeting the New South Zone ("NSZ") and a parallel Hanging Wall Zone ("HWZ").

Highlights:

• NSZ extended 89 feet (27.1 metres) down dip from previous intersections.
  • Drill hole 53-2705 returned 8.05 ounces per ton ("opt") uncut (5.02 opt cut), or 276.0 grams per tonne ("g/t") uncut, (172.1 g/t cut) over a true width of 6.7 feet (2.0 metres).
  • Drill hole 53-2822 returned 3.96 opt uncut (3.46 opt cut), or 135.8 g/t uncut, (118.6 g/t cut) over a true width of 6.4 feet (2.0m).
• NSZ extended 105 feet (32.0 metres) up dip and 53 feet (16.2 metres) east from previous intersections.
  • Drill hole 53-2704 returned 1.83 opt, or 62.7 g/t (no cutting factor applied), over a true width of 1.3 feet (0.4 metres).
  • Drill hole 53-2659 returned 1.92 opt, or 65.8 g/t (no cutting factor applied), over a true width of 1.9 feet (0.6 metres).
• Three new intersections on the HWZ help define the zone over a strike length of 200 feet (60.1 metres), with a 100 foot (30.5 metres) dip component.
  • Drill hole 53-2699 returned 3.69 opt uncut (2.17 opt cut), or 126.5 g/t uncut (74.4 g/t cut), over a true width of 7.0 feet (2.1 metres).
  • Drill hole 53-2701 returned 3.04 opt uncut (1.18 opt cut), or 104.2 g/t uncut (40.5 g/t cut), over a true width 15.8 feet (4.8 metres).
  • Drill hole 53-2818 returned 1.67 opt uncut (1.30 opt cut), or 57.2 g/t uncut (44.6 g/t cut), over a true width of 6.0 feet (1.8 metres).

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

Mr. George Ogilvie, Chief Executive Officer of the Company commented, "Since acquiring the properties associated with the Queenston Joint Venture in August of 2012, we have seen tremendous exploration success, particularly on the South Claims. In April of this year we reported 49,000 ounces of probable reserves (40,000 tons at an average grade of 1.23 opt or 42.2 g/t). As well, we announced an increase in indicated resources on the South Claims by 35%, and an increase in inferred resources by 19%, year over year. We are encouraged by these results and look forward to the possibility of expanding as well as improving our confidence of resources onto the HM Claim that remains open to the east."

"Since the Company commenced exploration activities, we have focussed on exploration associated with the Macassa Mine Complex which includes areas near the old Macassa Mine and the South Mine Complex. We now look to expand our exploration efforts and embark upon a regional program to test the four contiguous properties that lie to the east, with an initial investment of C$1.5 million, to be carried out during calendar 2015. We strongly believe in the robust nature of this camp, and our potential to extend our life of mine through organic growth."

SMC Underground Drilling on the HM Claim

The initial phase of drilling was spaced at an average of 120 foot (36.6 metre) intersections, while the infill drilling conducted recently has reduced the intersections to an average of 50 to 80 feet (15.2 metres to 24.4 metres) within the existing resource blocks.

Of the ten drill holes testing the NSZ inferred resource areas, and within the existing resource area, nine holes returned intersections which will make the minimum requirements to calculate an indicated resource (which is updated annually). Based on the conversion of the inferred resources to an indicated resource level, this represents a conversion rate of approximately 90%.

Of the five drill holes testing the NSZ inferred resources along the fringe areas of the current resource area, four returned intersections which will make the minimum requirements to calculate an indicated resource (which is updated annually). Based on the conversion of the inferred resources to an indicated resource level in these areas, this represents a conversion rate of approximately 80%, and is expected to expand the dip and strike components of the current resource blocks.

About the Company

Kirkland Lake Gold's corporate goal is to create a self-sustaining and long-lived intermediate gold mining company based in the historic Kirkland Lake Gold Camp. The Company plans to do this by mining to the reserve grade, generating profits and free cash flow for the shareholders. The Company will also look to take advantage of its increased infrastructure capacity in the appropriate gold price environment. At the same time, the Company is committed to maintaining a significant exploration program aimed at developing and maintaining a property wide reserve and resource base sufficient to sustain a mine life of more than ten years.

Over the last several years the Company has invested significant capital to improve the infrastructure of the business including upgrading the production hoist, skips, mill, underground mobile equipment and capital development. From initial discovery to present day there have been over 24 million ounces of gold mined from the Kirkland Lake camp while the current reserve and resource provides for potentially 14 years of mining with significant exploration upside.

Glossary of Terms

National Instrument 43-101 Definitions of Resources and Reserves

The Reserve and Resource estimation classifications as prescribed in National Instrument 43-101 are given here for clarity.

Mineral Resource

Mineral Resources are sub-divided into 3 categories depending on the geological confidence. The highest level with the most confidence is the 'Measured' category. The next level of confidence is the 'Indicated' category and the lowest level, or the resource with the least confidence, is the 'Inferred' category.

Inferred Mineral Resource

An 'Inferred Mineral Resource' is that part of a Mineral Resource for which quantity and grade or quality can be estimated on the basis of geological evidence and limited sampling and reasonably assumed, but not verified, geological and grade continuity. The estimate is based on limited information and sampling, gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes.

Indicated Mineral Resource

An 'Indicated Mineral Resource' is that part of a Mineral Resource for which quantity, grade or quality, densities, shape and physical characteristics, can be estimated with a level of confidence sufficient to allow the appropriate application of technical and economic parameters, to support mine planning and evaluation of the economic viability of the deposit. The estimate is based on detailed and reliable exploration and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that are spaced closely enough for geological and grade continuity to be reasonably assumed.

Measured Mineral Resource

A 'Measured Mineral Resource' is that part of a Mineral resource for which quantity, grade or quality, densities, shape and physical characteristics are so well established that they can be estimated with confidence sufficient to allow the appropriate application of technical and economic parameters, to support production planning and evaluation of the economic viability of the deposit. The estimate is based on detailed and reliable exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that are spaced closely enough to confirm both geological and grade continuity.

Mineral Reserve

Mineral Reserves are sub-divided into 2 categories. The highest level of Reserves or the level with the most confidence is the 'Proven' category and the lower level of confidence of the Reserves is the 'Probable' category. Reserves are distinguished from resources as all of the technical and economic parameters have been applied and the estimated grade and tonnage of the resources should closely approximate the actual results of mining. The guidelines state

"Minerals Reserves are inclusive of the diluting material that will be mined in conjunction with the Mineral Reserve and delivered to the treatment plant or equivalent facility." The guidelines also state that, "The term 'Mineral Reserve' need not necessarily signify that extraction facilities are in place or operative or that all government approvals have been received. It does signify that there are reasonable expectations of such approvals."

Probable Mineral Reserve

A 'Probable Mineral Reserve' is the economically mineable part of an Indicated and in some circumstances a Measured Mineral Resource demonstrated by a least a Preliminary Feasibility Study. This study must include adequate information on mining, processing, metallurgical, economic, and other relevant factors that demonstrate, at the time of reporting, that economic extraction can be justified.

Proven Mineral Reserve

A 'Proven Mineral Reserve' is the economically mineable part of a Measured Mineral Resource demonstrated by at least a Preliminary Feasibility Study. This study must include adequate information on mining, processing, metallurgical, economic, and other relevant factors that demonstrate, at the time of reporting, that economic extraction is justified.
