Step-Out Drilling Extends the SMC 500 Feet Further East; Drill Hole 53-2414 Assays 10.31 Ounces of Gold Per Ton (353.5 grams) Uncut Over a Core Length of 3.5 Feet (1.1 metres)

KIRKLAND LAKE, ONTARIO--(Marketwired - March 3, 2014) - Kirkland Lake Gold Inc. (the Company) (TSX:KGI)(AIM:KGI), an operating and exploration gold mining company, is pleased to announce drilling results from its ongoing underground diamond drilling exploration program. This latest program has served to further expand the mineralization associated with the South Mine Complex (SMC) on the HM claim and the North Amalgamated-Kirkland (North AK) claim. The HM and North AK claims were formerly held under a joint venture with Queenston Mining Inc. but were 100% acquired, along with other formerly joint venture properties, from Queenston on August 30, 2012.

This phase of the underground exploration program, from the Macassa 5,300 foot level, was designed to follow up on mineralized intercepts on the HM and North AK claims. (see the Company's news release dated September 19, 2013).

Mr. George Ogilvie, President and CEO commented, "This year's underground and surface exploration campaign was, for the most part, focused on drilling on the former joint venture properties, where in places, the average gold grades are greater than one ounce of gold per ton. The extension of the South Mine Complex "(SMC)" five hundred feet (500') to the east is extremely encouraging considering the Company's new business plan aimed at maximizing grade. To this end, all of our planned stope development for the remainder of fiscal year 2014 and 2015 will take place predominately in the SMC where the reserve grade is 0.52 ounces per ton."

"The intersection in drill hole 53-2414 represents a significant five hundred foot step out to the east from previous drilling, further reinforcing the exploration potential of this high grade complex." said Stewart Carmichael, Exploration Manager. "This is a SMC related footwall zone and will require follow up drilling over the next year to determine size and geometry. The SMC remains open to the east and we plan to extend the current drift in this direction to provide additional drill platforms with the intent to further expand the SMC. Results from these step out holes will not be included in this year's reserve and resource update as they were drilled after the December 31, 2013 cut-off date," added Mr. Carmichael.

The following are some of the highlights of the current exploration program:

• The intersection in drill hole 53-2432 (0.98 ounces per ton (opt) over a true width of 14.5 feet) is the furthest east intersection to date on the New South Zone and is located along the HM North AK boundary. This is the furthest east intersection on the New South Zone to date.
  
  
• The footwall intersection in drill 53-2414 (10.31 opt (3.5 opt cut) over a core length of 3.5 feet) has extended the SMC 500 feet east (a 39% increase) and brings the known strike length of the SMC to 4,100 feet which remains open in all directions at this point. The mineralization in this intersection comprises strong quartz veining within basic syenite associated with visible gold, tellurides and 2-5% fine pyrite.
  

This drill program is part of a larger long term exploration initiative. The Company is currently operating one exploration drill on surface and two exploration drills underground at the Macassa Mine.

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 10 years of mining with significant exploration upside.

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 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. entitled Review of Resources and Reserves of Macassa Mine, Kirkland Lake, Ontario at January 1, 2013 dated June 24, 2013, which has been filed on SEDAR (www.sedar.com) under the Company's filings.
