Kirkland Lake Gold Inc.: Wedged Hole Intersects 1.43 Ounces of Gold over 124.5 feet 'uncut' and Confirms New North-South Discovery

KIRKLAND LAKE, ONTARIO--(CCNMatthews - Aug. 15, 2005) - Kirkland Lake Gold Inc. (the "Company") (TSX:KGI)(AIM:KGI) is pleased to present an update on one of the programs in its three-year $21 million exploration campaign. The goal of this campaign is to explore for a combined potential of 15 million tons of ore on the Main Break, Parallel Breaks and North South structures, such as the Lower D Zone, on the Company's land holdings.

In a news release dated July11th an intersection of 90.4 feet assaying 2.3 ounces uncut from Drill Hole 50-627 was reported. Subsequently, a wedged hole was cut from that hole and has returned 1.43 ounces of gold per ton over 124.5 feet of core length (uncut- or 0.84 cut). The wedged hole has intersected the new discovery 49 feet vertically above and 140 feet up-dip from the discovery hole, Hole 50-627. These intersections are located 1,600 feet south of the active mine workings at the Company's #3 shaft.

Highlights of the current results from Wedge Hole 50-627W1 include:

- The apparent true width of the zone at the wedged drill hole is estimated to be between 34 and 35 feet (see figure #2).

- The mineralization intersected in the wedged hole is identical to the discovery hole though considerable more visible gold and tellurides were observed in the wedged hole of discovery hole

- The zone has an apparent dip ranging from 28 to 36 degrees (see figure #2). The azimuth is still unknown but estimated to be between 000 and 036 degrees.

-This new discovery appears to be a separate zone from the previously-reported LK Zone located 400' to the east (26.21 ounces of gold per ton over 6.0 feet uncut)

- Follow-up to this wedged hole will be three holes to be drilled to the south-west and one to the northeast. The first hole has started and is intended to intersect the zone 200 feet to the southwest in order to verify strike geometry.

"The discovery of wide, high-grade mineralization to the south of the 24-million ounce Main Break is adding significant confidence to our ability to substantially increase resources and reserves," said Company Chairman Harry Dobson. " The nine new zones discovered to date to the south of the Main Break workings are testimony to the potential out there and we will endeavour to turn that potential into high grade gold production. The Company's policy of trying to catch up on the historic exploration-drilling deficit is starting to pay off. "

Figure #1 is a plan view showing the two most likely orientations of the new discovery relative to other new ore-bearing structures to the south of the mine- including the Lower D, and the LK Zones (see figure #1)

Figure #2 is the detailed section through A-A' (as shown on the plan view) of 50-627 and 50-627W1 giving the apparent true width, apparent dip, and showing the assay distribution throughout the zone (see figure #2)

The angle that the mineralization cuts through the core averages 29 degrees in hole 50-627 and 35 degrees in hole 50-627W1. The grades are highest at the start and end of the two intersections, and are quite consistent through the rest of the intervals (see figure #2). Recently completed drill hole 47-1106 was extended in an attempt to intersect the new zone. This drill hole intersected an extensive trachyte flow 100 feet above and 300 feet up-dip from the projected mineralization and failed to intersect similar mineralization. Using the 000 orientation, the new discovery and the LK zone would line up with wide-spread alteration and mineralization, located 1300' down-dip, in drill hole 45-254, drilled by Lac Minerals in 1991 (mineralized from 2212' to 2613' down-hole -see figure #1).

To date, nine mineralized structures, including at least five North-South structures, have been discovered south of the active mine workings at Macassa. These may extend 5,000 feet or more; to date, the Lower D has ore-grade intersections for 2,700 feet horizontally. Historically, ore-bearing structures in Kirkland Lake are laterally very extensive (1,000 feet to 20,000 feet). Ore-grade shoots along these structures generally are also extensive (1,000 to 8,000 feet). An example of the extent of potential mineralization is the Teck-Hughes Mine, where 3,700,000 ounces of gold were mined from the Main Break over a strike length of only 1,400 feet (located on a single mineral claim).

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 Lake Gold, 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., for the purpose of NI 43-101, Standards of Disclosure for Mineral Projects).

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.
