Kirkland Lake Gold Ltd. (TSX: KL, NYSE: KL, ASX: KLA) announced that wide, high-grade intersections were reported at depth across the Saddle Zone within its Detour Lake property in Northern Ontario, Canada, confirming the potential for strong growth in Mineral Resources and Mineral Reserves in support of future open-pit and as well as underground mining.
The company said that the drilling in Central Saddle Zone intersected exceptional grades and widths, with key intercepts of 13.95 gpt gold over 26.9 m, including 108.94 gpt over 2.8 m.
KLA said that the drilling in Eastern portion of Saddle Zone confirmed continuity of mineralization to the west and below Main Pit reserve and resource pit shells, with key intercepts of 1.21 gpt over 105.9 m, 1.10 gpt over 120.3 m.
The company said that drilling below West Pit reserve shell intersected broad zones of mineralization extending to depth, with key intercepts of 1.47 gpt over 119.0 m; while drilling west of West Pit extended mineralization 300 m west of current Mineral Reserves, with key intercepts of 2.34 gpt over 11.3 m, including 11.5 gpt over 2.0 m.
Detour Lake exploration program
The company had recently commenced a 250,000 m exploration program at Detour Lake, which is targeted for completion by the end of 2021. The program was aimed at collecting 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.
KLA has now announced the results from 30 holes (21,928 m) of drilling at the Detour Lake property. They are the fourth batch of results from the exploration program and include the results from the holes drilled at the Saddle Zone and the area west of the West Pit.
High-grade results from drilling at Detour Lake
The company said that encouraging results were reported from the drilling at Central Portion of the Saddle Zone, East Portion of Saddle Zone, Below West Pit, and West Pit Extension.
Central Portion of the Saddle Zone
KLA said that said that nine holes (7,672 m) targeting the Detour Mine Trend (DMT) approximately midway between and 400 m below the Main and West Mineral Reserve pit shells were drilled in the central portion of the Saddle Zone.
Significant results included: 1.21 gpt over 105.9 m, 1.10 gpt over 120.3 m, 2.17 gpt over 39.0 m, 1.61 gpt over 29.0 m, 1.61 gpt over 29.6 m, and 0.80 gpt over 51.0 m, from hole DLM-21-089B; 1.01 gpt over 118.0 m and 0.83 gpt over 26.0 m, from hole DLM-20-47W2; and 1.09 gpt over 57.0 m, including 14.38 gpt over 2.0 m and 0.78 gpt over 26.8 m from hole DLM-20-062.
Below West Pit
The company said that the drilling below the west pit included five holes (4,059 m) which targeted the DMT directly east of the West pit between 350 and 500 m below surface.
Important results included: 1.47 gpt over 119.0 m, 0.71 gpt over 57.0 m and 1.64 gpt over 19.7 m from DLM-20-024A; 0.92 gpt over 128.0 m, 1.09 gpt over 35.0 and 9.14 gpt over 4.0 m from hole DLM-20-050B; 0.95 gpt over 100.1 m from hole DLM-20-056B; and 0.99 gpt over 48.0 m, 1.73 gpt over 13.4 m and 13.92 gpt over 2.0 m from hole DLM-20-064.
West Pit Extension
KLA reported that the drilling in the east portion of the Saddle Zone included seven new holes (2,092 m) which targeted areas of the DMT west of the West Pit Mineral Reserve up to 125 m below surface.
High-grade results included 2.34 gpt over 11.3 m, including 11.5 gpt over 2.0 m from hole DLM-20-071; and 1.76 gpt over 11.0 m in hole DLM-20-083 and 7.31 gpt over 5.0 m from hole DLM-20-045.
Latest updates and next steps
The company said that based on assay results and other observations obtained from the program to date, the outlook for the project continues to look encouraging with there being evidence of a broad and continuous corridor of mineralization extending between the West and Main pits and to a depth of at least 800 m below surface.
KLA said that the work also suggests that mineralization within the corridor is very similar to that found in the West and Main pits.
The company expressed confidence that there is a high potential to identify further extensions to mineralization as well as additions to Mineral Resources and Mineral Reserves between the Main and West pits through additional drilling.
Kirkland said that the exploration work at Detour Lake is ongoing with twelve drills currently working, and on track to complete approximately 270,000 m by the end of 2021.
President and CEO of Kirkland Lake Gold, Tony Makuch said: “With today’s results, we are increasingly confident that a large continuous deposit is situated along the Detour Mine Trend (“DMT”) that extends from the Main Pit, through the Saddle Zone and continues beyond the West Pit location. We are also extremely encouraged by the wide, high-grade intersections being reported at depth across the Saddle Zone, which confirm the potential for strong growth in Mineral Resources and Mineral Reserves in support of future open-pit and as well as underground mining.
We are already introducing significant enhancements to the Detour Lake operation through re-interpretations of previous work and project improvements, with our progress to date highlighted in a new NI 43-101 technical report to be filed by the end of this month. This report will include production results consistent with our previously-released guidance of 680,000 – 720,000 ounces per year for 2021 – 2023, with production to increase to approximately 800,000 ounces in 2025. This report will not include any of the new drilling we have done since the acquisition.
The exploration success we are achieving will be part of a completely new mine plan and technical report to be issued early next year, which we believe will clearly demonstrate the substantial value upside we have through our extensive commitment to exploration drilling at Detour Lake Mine.”
