Kirkland Lake Gold hits new wide, High-Grade intersections at Detour Lake

May 5, 2021

“We continue to have a great deal of success drilling along the DMT," Tony Makuch, President and CEO of Kirkland Lake Gold said.  Kirkland Lake Gold Ltd. has announced results from 38 holes and two wedge holes (23,911 m) of drilling along the Detour Mine Trend (“DMT”) at the Detour Lake property.

"New wide, high-grade intersections continue to confirm the continuity of the mineralized corridor connecting the Main Pit and planned West Pit. We are also having success intersecting high-grade mineralization near the bottom of the Mineral Resource pit shell in the Saddle Zone, which highlights the potential to add significant new open-pit, and possibly underground, Mineral Resources. We also continue to expand mineralization to the west of the planned West Pit, indicating that we have yet to determine the full expanse of the deposit running along the DMT. We are continuing our extensive drill program at Detour Lake, following up on each of the key targets, with 12 drills currently working and plans to complete 270,000 m of drilling during 2021.

The new holes being reported are the fifth batch of results from the recently announced 270,000 m exploration program, which the Company is targeting for completion by the end of 2021. The program is being completed to collect information for an updated, and potentially expanded, Mineral Reserve and to support the completion of a new production plan, expected to be released in early 2022. Most of the new holes announced today are from drilling in the Saddle Zone, located between the existing Main Pit and planned West Pit locations, which has been underexplored and has no Mineral Reserves and only limited Mineral Resources. Several new holes are also being announced from the area west of the West Pit Mineral Reserves, which also contains limited past drilling.


“When we issued the new technical report for Detour Lake at the end of March, we described it as an important milestone for the project that included expanded production, low unit costs, a long mine life and attractive economics. We also indicated that it was very much an interim report, that we fully expect to improve upon when we factor the substantial exploration success we are achieving into a new technical report and life-of-mine plan next year. The drilling results we have announced today provide us with even greater confidence that the 2022 technical report will clearly establish Detour Lake as one of the world’s premier gold mines.”
