NORTHERN ONTARIO – In the middle of a three-year, $21-million exploration program, KIRKLAND LAKE GOLD has solid results from the Lower D zone. Significant intersections included 1.10 opt Au over 18 ft and 3.00 opt Au over 11 ft. The company thinks it can identify a potential strike length of 2,700 ft. Kirkland Lake operates the Macassa gold mine in Kirkland Lake, Ont.

Mineralization in all but one of the holes to date on the Lower D comprises carbonate- altered conglomerate mineralized with up to 10% disseminated pyrite. The mineralization in the other hole comprises porphyry-hosted quartz veining and silicification.

“Our main focus right now is to extend the Lower D and the parallel LK zones north towards the operational workings at the Macassa No.3 shaft, correlate the multiple zones intersected to date, and verify the dip geometry with the view of bringing in resources,” said Stew Carmichael, chief exploration geologist. “Though most of the historical production in the Kirkland Lake camp was derived from east-west-trending structures such as the Main Break, the new north-south-trending mineralization, originally discovered by KGI exploration staff in February 2003 with the Upper D zone and including these latest results, represents the most significant exploration development since the inception of the three-year program.”

To date, four north-south structures have been discovered at Macassa, each of which may extend 5,000 ft or more. Historically, ore-bearing structures in Kirkland Lake are laterally very extensive (1,000 to 20,000 ft). Ore-grade shoots along these structures generally are also extensive (1,000 to 8,000 ft).
