NEW “D” ZONE INTERSECTIONS INCLUDE 1.42 OZ/T OVER 8.0’ UNCUT, INCREASING RESERVES IN NEW MINING LEVELS UPPER SHAFT #3

Kirkland Lake Gold Inc. (the “Company”) is pleased to announce results from the “D” Zone definition drilling program at the Macassa Mine, one of nine exploration programs underway across the Company’s Kirkland Lake properties. The D zone consists of a south and a north block (also known as stopes 3833 and 3824) that are located above the 3800 level in Shaft #3. The south block contains a previously reported (see news release dated March 1^st, 2004) probable reserve of 80,500 tons of 0.86 oz./ton gold (69,286 ounces), plus an inferred resource of 9,109 tons of 1.02 oz./ton gold (9,291 ounces). This same news release reported the north block – together with the C vein - contained an indicated resource of 42,002 tons of 0.79 oz./ton gold (33,182 ounces) plus an inferred resource of 31,603 tons of 0.56 oz./ton gold (17,698 ounces). In the foregoing calculations, the mining dilution was calculated at 35% at 0.02 oz/ton gold. Reserves are not part of resources and resources do not have demonstrated economic viability. These resources and reserves are as at March 1, 2004.

Definition drilling has started on the D Zone north area and is returning intersections such as 1.42 ounces of gold over 8.0 feet (7.8 feet - true width (“TW”)) uncut (or 1.21 ounces of gold over 8.0 feet cut), and 0.52 ounces of gold over 13.2 feet (11.0 feet - TW). Other results include an intersection of 0.71 ounces of gold per ton over 5.4 - feet TW and 0.52 ounces of gold over 6.6 feet TW.

“This program is both converting resources to reserves with attractive 8 to 20 foot horizontal mining widths, as well as extending the resources further above the new 34 level that is being driven” said Mike Sutton, Chief Geologist. “We are increasing the drilling focus in order to substantially expand these zones which are wide open above and in the north-south directions.”

“The Company is actively developing the D zone on the 34 and 38 levels with a target of June for the first heading to be into ore production, and ultimately to have six to eight working headings with mechanized mining methods on both the 3833 and 3824 ore blocks, “said Company President, Brian Hinchcliffe. “Our target remains to develop 500,000 ounces in reserves by end of calendar year 2004 in the upper horizon of Shaft #3, above the 4200 level, apart from the other definition drilling programs.”

New drilling has defined a roughly 30 degree west-plunging central area of high grades (0.94 ounces of gold per ton to 1.21 ounces of gold per ton). This area also contains ore with good mining widths (8.3 feet to 19.9 feet horizontal mining widths, or 7.5 feet to 11.0 feet true widths). The attached longitudinal section shows the new drill holes (figure 1), the old indicated resource, and this high-grade, wide-ore plunge. The 3824 stope (of the D zone north) is open in most directions, and the high-grade within it is also open.

Of particular interest in the latest drilling are holes 38-294 which intersected 0.52 ounces of gold over 13.2 feet (11.0 feet TW), and 38-288 which returned 1.42 ounces of gold

over 8.0 feet (7.1 feet TW) uncut (or 1.21 ounces of gold over 8.0 feet cut). Hole 38-294 expands the wider portion of the zone 80 feet up-dip above previously reported drill hole 38-206 (that had returned 0.96 ounces of gold over 7.5 feet (5.4 feet TW)). Hole 38-288 expands the high-grade portion of the zone 70 feet south of hole 38-206.

Several drill holes have intersected other new zones of significant grade. Hole 38-278 has returned 19.27 ounces of gold over 1.4 feet (unknown TW), hole 38-282 has returned 1.23 ounces of gold over 4.1 feet (unknown TW), and hole 38-285 intersected 2.33 ounces of gold over 1.0 feet (unknown TW). These “new” zones are not included in any resource calculation. Definition drilling is currently in the process of drilling the area surrounding holes 38-201 to 38-227 in order to add more to the probable reserves. Further drilling is about to begin to test the area surrounding hole 38-228 as well as the parallel vein (C Vein).

Drilling is currently being undertaken on 50 to 100 foot centres. Ore reserve and resource criteria and methodology can be found on the Company’s web site.

Very little drilling has been carried out historically at Macassa to the south of the primary ore structure, the ’04 Break. The newly-discovered D Vein is one example of what exists to the south (i.e. the Hangingwall). 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). Based on existing drilling, this new zone is mineralized for 1300 feet down-dip by 1100 feet on strike. The “D” Zone is open in most directions.

Though most ore zones in Kirkland Lake are east-west striking, this zone is north-south striking. The D Zone projects close to Shaft #3 thus enhancing the economics of developing two new levels at both 3400 and 3000 elevations. The 3400 level development is being excavated along the new D Zone out north to the primary host structures at the Macassa Mine –the ‘04 Break and the South Zone.

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 kilometers between the Macassa Mine on the east and Wright Hargreaves on the west and for the first time will be 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.
