Kirkland Lake Gold Inc.: Initial Drifting in March on New South Mine Provides 1,000 Tons of 1.5 Ounces of Gold Per Ton

KIRKLAND LAKE, ONTARIO--(CCNMatthews - April 10, 2007) - Kirkland Lake Gold Inc. (the "Company") (TSX:KGI)(AIM:KGI) is pleased to announce an update on the development of the new, high grade ore systems that have been discovered to the south of the historic Main Break, recently termed the "New South Mine". The New South Mine consists of 15 or more mineralized gold zones that have been discovered to date which are located 1,000 feet and beyond to the south of the Main Break. These zones, which are open in all directions, are the focus of an exploration program which will include six drills working underground on the 5000 and 5300 foot levels.

Access development drifting is currently in progress on various mineralized zones in the New South Mine complex. The drifting will be used to further define the mineralization, converting resources to reserves, preparing stopes for mining and providing additional platforms for more efficient exploration drilling. For the month of March, the average recorded grade from 1,000 tons of development round much samples taken from the Lower D North Zone was 1.51 ounces of gold per ton ("opt").

"Thus far the grades returned from the drifting in the New South Mine are close to or in some instances, better than the grades indicated from the exploration drilling," said Michael Sutton, Chief Geologist. Duncan Middlemiss, Mine Manager, added, "Developmental drifting in the New South Mine has progressed as planned and returned exceptional ore results which have been blended with the ore mined from the Main Break."

Highlights of the current results:

- Drifting east on the Lower D North Zone has defined two extensive ore shoots. Chip samples from the first shoot have averaged 0.72 opt (1.02 opt uncut) over 7.5 feet over a drift length of 278 feet. Exploration drilling indicated a grade of 0.78 opt (1.04 opt uncut) over a narrower mining width of 5.9 feet. A second shoot has thus far averaged 0.92 opt (1.27 opt uncut) over 7.8 feet over a drift length of 178 feet. Exploration drilling in this area indicated a grade of 0.80 opt (1.78 opt uncut) over a vertical mining height of 13.8 feet with horizontal width up to 25 feet in places. The mineralization extends across the entire drift and into both drift walls. Close-spaced definition drilling will be implemented to ascertain the true dimensions (see figures 1 and 2).

- Drifting east on the Lower D North Footwall Zone has averaged 0.91 opt (1.62 opt uncut) over 7.4 feet over a drift length of 135 feet with a second shoot averaging 0.72 opt over 8.7 feet over a drift length of 40 feet. Exploration drilling in this area indicated 0.79 opt (1.08 opt uncut) over 6.6 feet mining width and 1.05 opt (2.51 opt uncut) over 5.0 feet mining width.

- Drifting west on the #7 Break over a distance of 107 feet has averaged 0.77 opt (1.04 opt uncut) over a vertical mining height of 7.6 feet. Exploration drilling in this area indicated a grade of 0.43 opt (0.84 opt uncut) over a vertical mining height of 6.5 feet.

- Continuity of the zones appears good, and orientations are in keeping with the original drill interpretation.

- Initial cross cutting and drifting on zones between July 2006 and January 2007 contributed 2,088 ounces of gold to production over a six month period. An additional 482 ounces were produced in February 2007 from the access drifting.

- Thus far, the ore is all characterised by sulphide mineralization and is structurally controlled, often accompanied by a lithological contact between porphyry and tuff.

- Blending of the new sulphide mineralized zones to the south with the more typical quartz vein material derived from the `04 Break system has not had any adverse effects on recoveries which are in the 97% range.

- The new muck pass system from 5000 level to 5600 level is scheduled for completion for the end of April. This new pass will allow for greater flexibility in handling both ore and waste from the zones to the south.

About the Company

The Company purchased the Macassa Mine and the 1,500 ton per day mill along with four former producing gold properties - Kirkland Minerals, Teck-Hughes, Lake Shore and Wright Hargreaves - in December 2001. These properties, which have historically produced some 22 million ounces of gold, extend over seven kilometres between the Macassa Mine on the east and Wright Hargreaves on the west and, for the first time, are being developed and explored under one owner. This camp is located in the Abitibi Southern Greenstone Belt of Kirkland Lake, Ontario, Canada.

Qualified Person Review & QA/QC Program

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', Michael Sutton, P.Geo., the Company's Chief Geologist, for the purpose of National Instrument 43-101 Standards of Disclosure for Mineral Projects, of the Canadian Securities Administrators).

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 half of the core samples shipped to the Swastika Laboratories in Swastika, Ontario or to the Macassa mine laboratory for analysis. 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/rejects at alternate certified labs (Polymet, Accurassay). 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.
