The current phase of the underground exploration program, from the Macassa 5,300 foot level, was designed to further extend and upgrade resources on the South Claims to the -5900 foot elevation from a recently completed cross cut to the south as well as additional exploration on the HM claim up dip and along strike. Surface drilling to 1,000 feet below surface further tested mineralization associated with the Amalgamated Trend, located approximately 4,000 feet south of the historically mined Main Break.

Details of the drilling highlights are as follows:

• The intersection in drill holes 53-2589 (1.48 opt (50.7 gpt) over a true width of 9.4 feet) and 53-2590 (0.30 opt (10.3 gpt) over a true width of 5.4 feet) have extended the New South Zone an additional 288 feet down-dip on this part of the South Claims. A new footwall zone was intersected as well in 53-2590 which assayed 12.90 opt (442.3 gpt) over a core length of 1.0 feet, approximately 53 feet below the New South Zone. A deeper, unrelated footwall zone, was intersected in drill hole 53-2591 and assayed 17.34 opt (594.5 gpt) over a core length of 1.7 feet. This intersection represents the deepest intersection to date on the South Claims, at the -5,855 foot elevation, 180 feet below the New South Zone.

• Drill hole 53-2588 tested an inferred resource area on the South Claims and assayed 0.48 opt (16.5 gpt) over a true width of 31.0 feet. To the northeast of the South Claims, drill hole 53-2496 tested a large inferred resource area on the HM Claim. This drill hole assayed 1.22 opt (41.8 gpt) over a true width of 25.6 feet. Both intersections will upgrade the resource category. Drill hole 53-2497 (0.57 opt (19.5 gpt) over 4.7 feet true width) has extended the New South Zone on the HM claim an additional 125 feet north and up-dip.

• The definition drilling program currently underway from surface within the Amalgamated Trend resource area has identified two new additional lenses of gold mineralization which lie in the footwall of the current FW 3 resource block on the South Claims property. The dip of these zones appears to be shallower than the current resources in the area (

• These drill holes cover an area approximately 400 feet along strike and 170 down the dip of these new mineralized zones and lie 270 to 360 feet below surface. The mineralization in these zones is of the same style as that of the current resource blocks and comprises quartz/carbonate veining generally within sericite/carbonate altered sediments with up to 5-7% pyrite and visible gold.

Technical Information and Qualified Person Notes

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 (which includes a 'qualified person', Stewart Carmichael P.Geo. the Company's Chief Exploration Geologist, for the purpose of National Instrument 43-101, Standards of Disclosure for Mineral Projects, of the Canadian Securities Administrators). Mr. Carmichael also supervised the preparation of the information that forms the basis of the technical disclosure and reserve estimates in this release.

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.

The Company's Macassa Mine Property is the subject of a reserve report prepared by Glenn R. Clark, P.Eng. titled Review of Resources and Reserves of Macassa Mine, Kirkland Lake, Ontario at January 1, 2014 dated June 5, 2014, which has been filed on SEDAR (www.sedar.com).

About the Company

Kirkland Lake Gold Inc.'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.

Neither the Toronto Stock Exchange nor the AIM Market of the London Stock Exchange has reviewed and neither accepts responsibility for the adequacy or accuracy of this news release.

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.
