KIRKLAND LAKE, ONTARIO--(Marketwire - Oct. 5, 2010) - Kirkland Lake Gold Inc. (TSX:KGI)(AIM:KGI) (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.

"This latest round of drilling not only confirms the strength of mineralization on the east portion of the South Mine Complex, but also increases both the down and up dip components," said Stewart Carmichael, Chief Exploration Geologist. He added, "As planned, we now have most of the exploration drills working on a 14 shift per week schedule including a new drill bay on the 5300 level to test the up dip component of the SMC."

Recent drilling from one of several exploration programs currently in progress has extended the east portion of the New South Zone down dip and up dip of the previous known limits and includes the following results:

- Drill hole 53-1657 has intersected the New South Zone and assayed 2.48 ounces of gold per ton (opt) uncut (0.73 opt cut) over a core length of 16.2 feet (estimated 14.7 feet true width). This intersection is located 100 feet down dip of previously reported drill hole 50-1153 which assayed 0.77 opt over a true width of 5.5 feet (see the Company's news release dated June 15, 2010). (see figure 1: http://media3.marketwire.com/docs/figure1KGI.pdf)

- A second new drill hole, 53-1656, intersected the New South Zone and assayed 0.36 opt over a core length of 9.6 feet (estimated 9.3 feet true width). This intersection is located 60 feet down dip of previously released drill hole 53-1519 (1.11 opt over a true width of 1.9 feet) and 120 feet west of 53-1657. (see figure 1)

- Drill holes 53-1594 and 53-1595 tested a blank gap within the central portion of the New South Zone between the 5500 and 5700 levels. Both holes intersected high grade mineralization. Drill hole 53-1594 assayed 3.06 opt uncut (2.21 opt cut) over a true width of 6.5 feet and included 10.53 opt over a true width of 1.7 feet. Drill hole 53-1595 assayed 1.16 opt over a true width of 18.1 feet.

- Drill hole 53-1675 intersected the New South Zone and assayed 5.00 opt over a true width of 0.6 feet. This intersection is located 210 feet up dip from previously released drill hole 53-1506 which assayed 8.60 opt uncut (3.5 opt cut) over an approximate true width of 5.2 feet. Though bracketed by two weak drill holes (53-1522 and 53-1523), this intersection may represent the opening of a new lens of the New South Zone, open up dip.

A larger capacity drill has been mobilized into the 5305 drift in this area of the SMC and will concentrate on testing the possible extension of the `08 Break as intersected in drill hole 53-1520 which assayed 6.14 opt uncut (1.82 opt cut) over an estimated true width of 11.8 feet. (see the Company's news release dated January 12, 2010). Further testing of the New South Zone will begin in early 2011 upon completion of a new drill bay to be located at the east end of the 5305 drift.

The figures referred to in this release may be viewed at the Company's website at www.klgold.com and will provide context to the above statements. Figure 1 is a plan view showing the latest drilling results on the New South Zone.
