Kirkland Lake Gold Inc.: Latest Drilling on New South Zone Returns 1.49 Ounces Over 39 Feet; Lower D Zone Results Advance Mine Planning

KIRKLAND LAKE, ONTARIO--(CCNMatthews - April 11, 2006) - Kirkland Lake Gold Inc. (the "Company") (TSX:KGI)(AIM:KGI) is pleased to announce an update on exploration drilling to the south of the No. 3 Shaft.

The Company has completed two additional drill holes on the New South Zone, as part of a continuing exploration campaign on a new discovery made in July, 2005 in which the initial two drill holes intersected 90.4 feet assaying 2.3 ounces (uncut) and 1.43 (uncut) ounces of gold per ton ("opt") over 124.5 feet of core length (uncut). One additional hole has also been completed on the Lower D Zone as part of an on-going program to expand the Lower D Zone north of the existing reserve/resource block.

"The fact that we have intersected ore-grade mineralization on eight of the nine holes completed to date on the New South Zone indicates the substantial ore potential of this completely new sulphide ore body," said Mike Sutton, Chief Geologist. "In addition, the strategic importance of the latest drill results on the Lower D Zone will advance plans for a new drift from the 5025 level to permit mining of the Lower D and #6 splay for the first time in the upcoming twelve months."

Highlights of the current results:

- Drill Hole 50-697W1 assayed 1.49 opt over 39.8 feet of core (uncut or 0.40 opt cut) and is located 50 feet west of previously released drill hole 50-669W1 (0.38 opt over 42.0 feet) and 174 feet up-dip of previously released drill hole 50-666 (1.91 opt over 15.3 feet, uncut). These holes have defined the west flank of the New South Zone as having a steeper dip for the zone between 42 and 45 degrees.

- Drill Hole 50-705 assayed 0.36 opt over 15.9 feet of core and is located 160 feet up dip from previously released drill hole 50-668 (1.30 opt over 12.0 feet) and represents an intersection on the east flank of the zone where the mineralization dips at 25 degrees. Also of note is the broad low-grade mineralization intersected (0.09 opt over 100.7 feet) indicating that the intersection is close to the higher grading mineralized corridor as indicated by the initial discovery and wedged holes 50-627 and 50-627W1 (2.30 opt over 90.4 feet and 1.43 opt over 124.5 feet respectively). A plan view showing the location of the latest intersections are included in this release (see figure #1).

- In house metallurgical testing on core samples submitted from the New South Zone indicate that a 96.2% recovery may be achieved by using standard milling procedures.

- The next phase of drilling (minimum two holes) will be wedged holes from previously released drill hole 50-696 (1.31 opt over 9.6 feet). Drill hole 50-696 represents a possible 880 foot down-dip extension on the west flank of the New South Zone and the planned wedged holes are designed to verify continuity.

- The five-hole program of infill drilling immediately to the north of the existing Lower D Zone resource/reserve block at 100 to 150 foot centers over a strike length of 600 feet has been completed using the large electric drill. Updated resource calculations are in progress which will reflect the expanded mineralization (see figure #2).

- At the closest point known to date, the Lower D Zone is located 1,200 feet south of the operational workings on the 5025 level, and the #6 Splay is located 900 feet south of the 5025 level. At the 5025 Level the Lower D is now known to be virtually continuous ore over a length of 1,050 feet followed by a further 850 feet of unexplored distance to the next drill hole which returned an ore-grade intersection (drill hole 50-622 which assayed 3.24 opt over 1.0 feet core length).

- The new 5300 level exploration drift has now been driven 650 feet to the south with drill bays completed and closer spaced drilling at 100 foot centers utilizing smaller air machines on the Lower D Zone has commenced. This program is designed to both convert inferred resources to indicated resources and further expand the Lower D Zone to the north.

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.

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.
