KIRKLAND LAKE GOLD INC.

New Drilling Continues to Extend the South Mine Complex;

Expansion More Than 300 Feet East of Previous Limit 

Kirkland Lake Gold Inc. (the Company), an operating and exploration gold mining company, is pleased to announce that recent underground exploration drilling has resulted in the further expansion of the South Mine Complex (SMC) on the Company?s 100% owned Macassa property. The SMC now consists of 25 or more mineralized zones, some of which are now in production while others are being explored and developed under the Company?s exploration and ore-body definition programs.

Recent drilling from one of several exploration programs currently in progress has extended the SMC 340 feet east of the previous known limits.

• Drill hole 50-1242 has intersected the New South Zone and assayed 6.24 ounces of gold per ton (opt) uncut (4.82 opt cut) over a core length of 12.5 feet (estimated 3.0 feet true width). A second zone interpreted to represent a hanging wall zone to the New South Zone returned 2.10 opt over a core length of 3.9 feet (estimated 0.9 feet true width). The hanging wall intersection has effectively extended the South Mine Complex 340 feet further east than previously released drill hole 53-1506 which intersected the New South Zone and assayed 8.60 opt uncut, 3.50 opt cut over an estimated true width of 5.2 feet. (see the Company?s news release dated January 12, 2010)

• Infill drilling, which forms part of this release, has shown that the intersection in drill hole 53-1506 (8.60 opt over 5.2? true width), previously interpreted to be footwall to the New South Zone, is reinterpreted as being on the New South Zone itself as it begins a northerly change in strike.

• In addition, drill hole 50-1153 has extended the New South Zone 160 feet down dip from the above previously released drill hole 53-1506 and assayed 0.77 opt over a true width of 5.5 feet. 

• Drill holes 53-1520 to 53-1524 all intersected the structure controlling the New South Zone but returned negligible assays. These holes likely lie outside the east-trending flat plunge line for the zone.

• Both hanging wall and footwall mineralization to the New South Zone has been intersected in many of the recent drill results.

?Since January we have extended the South Mine Complex more than 500 feet east of the previously defined limit. We now have numerous drill targets in this area of the Macassa Mine to test over the next year including the New South Zone and the recently discovered Lower SMC or `08 Break.? said Stewart Carmichael, Chief Exploration Geologist.  He added, ?We also plan to increase exploration drilling from 8 shifts per week to 14 shifts per week upon completion of the new dry facility, which will allow for a 56% increase in exploration drilling starting in July.?

The figure referred to in this release may be viewed at the Company?s website, www.klgold.com  and will provide context to the above statements. Figures 1, 2 and 3 are plan views showing the latest drilling results on the New South Zone and subsidiary footwall and hanging wall intersections.

 The following table summarizes the latest drilling results (Imperial values)

TW = True Width, CL = Core Length, VG = Visible Gold, Tell = Tellurides, *Cut = cut to 3.5 opt,

 **Cut = cut to 7.2 opt  ?? TW = Unknown True Width, TW NC = True Width Not Calculated

The following table summarizes the latest drilling results (Metric values)

TW = True Width, CL = Core Length, VG = Visible Gold, Tell = Tellurides *CUT = cut to 120.0 grams/tonne, **Cut = 247.0 grams/tonne ?? TW = Unknown True Width, TW NC = True Width Not Calculated

About the Company

The Company purchased the Macassa Mine and the 1,450 ton per day mill along with four former producing gold properties ? Kirkland Lake, 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 to the west and Wright Hargreaves to the east and, for the first time, are being developed and explored under one owner. This camp is located in the Southern Abitibi 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?, 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, or to Polymet Resources Inc. in Cobalt, 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.
