TORONTO, Dec. 23, 2020 (GLOBE NEWSWIRE) -- Kirkland Lake Gold Ltd. (“Kirkland Lake Gold” or the “Company”) (TSX:KL) (NYSE:KL) (ASX:KLA) today announced results from 25 holes (19,523 m) and one wedge hole (1,110 m) of drilling at the Detour Lake property. The new holes being reported are the third batch of results from the recently announced 250,000 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 as well as to support the completion of a new production plan. Most of the new holes announced today are from drilling in the Saddle Zone, located between the Main Pit and 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, which also contains only limited past drilling.
Tony Makuch, President and CEO of Kirkland Lake Gold, commented: “Today’s results provide further evidence that a much larger and higher-grade deposit exists around the Main Pit and West Pit locations at Detour Lake Mine than is currently included in Mineral Reserves. We continue to intersect broad zones of mineralization in the Saddle Zone between the two pits, which demonstrates the potential for continuous mineralization over very large area and supports our view that a much larger pit design concept may be warranted leading to substantial Mineral Reserve growth, increased levels of production and improved unit costs. In addition, with a growing number of high-grade intersections at depth, we are increasingly optimistic that both production levels and average grades can be augmented through the addition of an underground mining operation. We are also very encouraged by drill results on the west side of the property, which include extending mineralization 200 m west of the current West Pit location. We are still relatively early in our 250,000 m drill program and expect 2021 to be a very important year for establishing the full potential of the Detour Lake Mine.”
East Portion of Saddle Zone
Drilling in the east portion of the Saddle Zone included nine holes (7,586 m) and targeted areas along the Detour Mine Trend (“DMT”) directly west of the Main Pit Mineral Reserve shell between surface and 500 m below.
Significant results from the drilling including: 4.38 gpt over 31.0 m, including 47.46 gpt over 2.0 m and 5.45 gpt over 3.2 m, from hole DLM-20-028, 1.50 gpt over 75.0 m, including 3.59 gpt over 23.0 m, 1.33 gpt over 14.7 m, 0.87 gpt over 30.9 m and 0.78 gpt over 21.0 m from hole DLM-20-035, 1.11 gpt over 58.0 m and 0.73 gpt over 34.0 m from hole DLM-20-026 and 1.12 gpt over 46.0 m, 0.69 gpt over 17 m and 3.02 gpt over 4.0 m from hole DLM-20-020. All of these new holes were designed to intersect the DMT between surface and 200 m below and strongly confirmed the continuation of the DMT west of the current Main pit reserve.
Additional significant results from this area include: 4.02 gpt over 43.0 m, including 37.19 gpt over 3.0 m, 2.58 gpt over 70.9 m, including 31.05 gpt over 2.0 m, 1.00 gpt over 51.8 m, 0.78 gpt over 87.8 m and 1.40 gpt over 28.0 m from hole DLM-20-025A, 1.99 gpt over 55.4 m, 1.35 gpt over 63.0 m, 1.26 gpt over 76.0 m, 1.67 gpt over 37.0 m, 1.49 gpt over 36.3 m and 0.94 gpt over 65.0 m from hole DLM-20-041 and 1.64 gpt over 62.8 m, including 2.43 gpt over 34.8 m, 0.80 gpt over 68.0 m, 0.81 gpt over 74.0 m and 2.30 gpt over 14.0 m from hole DLM-20-039 which targeted the DMT between 200 and 450 m below surface. As with the new near surface holes the drilling here strongly confirms the extension of mineralization westwards from the Main pit as well as results from previously reported from DLM-20-014A which intersected 1.42 gpt over 78.0 m, 1.08 gpt over 51.0 m, 1.21 gpt over 43.0 m and 0.90 gpt over 51.0 m (see press release dated September 9, 2020) in the area approximately 75 m east of DLM-20- 025.
Central Portion of the Saddle Zone
Drilling in the central portion of the Saddle Zone included five holes (4,563.5 m) and targeted the DMT approximately midway between the current reserve pits for the Main and West pits and between 100 and 500 m below surface.
Significant results from the drilling include: 1.10 over 67.0 m, 2.53 gpt over 18.0 m, 0.83 gpt over 27.7 m, and 0.94 gpt over 24.0 m, including 15.91 gpt over 2.0 m, from hole DLM-20-022, 2.65 gpt over 24.0 m, including 9.14 gpt over 5.0 m, 0.80 gpt over 79.0 m, 1.94 gpt over 13.6 m, from hole DLM-20-046B and 0.72 gpt over 76.0 m from hole DLM-20-44 which targeted the DMT between 100 and 250 m below surface. All of three of the new holes are considered highly successful and strongly demonstrate the continuity of mineralization along the DTM through the central part of the Saddle Zone and its extension to surface. The new intersections in hole DLM-20-046B are located approximately 100 m above previously reported results from Hole DLM-20-016 which included 1.10 gpt over 142 m, including 9.39 gpt over 2.0 m, 2.15 gpt over 16.0 m and 1.23 gpt over 12.0 m (see press release dated September 9, 2020).
Additional significant results from this area include: 8.13 gpt over 17.0 m, including 22.51 gpt over 5.9 m, 2.63 gpt over 21.3 m, including 20.39 gpt over 2.0 m; 2.34 gpt over 42.7 m, including 25.60 gpt over 2.5 m and 1.06 gpt over 40.0 m from DLM-20-037 and 1.54 gpt over 13.0, 0.89 gpt over 49.8 m and 0.82 gpt over 54.7 m from DLM-20-19 which intersected the DMT between 400 and 550 m below surface, demonstrating strong potential for expansion of the system to depth.
Results from all holes in this area are considered extremely encouraging as they continue to confirm the presence of a broad corridor of mineralization extending between the West and Main pits ( a distance of over 800 m) with the overall style of mineralization and gold tenor being very similar to that found in the West and Main pits.
West Portion of Saddle Zone
Drilling in the west portion of the Saddle Zone included two holes (2,403 m) and one wedge hole (1,110 m) which targeted the DMT directly east of the West pit between 400 and 550 m below surface.
Significant results from the drilling include: 1.85 gpt over 24.7 m and 1.86 gpt over 37.9 m, including 13.30 gpt over 2.0 m, from DLM-20-027W; 1.00 gpt over 44.7 m, including 9.84 gpt over 2.1 m and 0.88 gpt over 34.0 m, from hole DLM-20-021B; and 0.88 gpt over 42.0 m, 0.81 gpt over 58.0 m and 3.13 gpt over 6.0 m, from hole DLM-20-018. Hole DLM-20-27W intersected the DMT approximately 325 m below surface and 75 m above previously reported DLM-20-004 which included results of 1.41 gpt over 121.0 m and 1.03 gpt over 14.08 gpt (see press release dated June 29, 2020), while DLM-20-21B and DLM-20-018 intersected the DMT approximately 75 and 150 m below DLM-20-004.
Results from all three holes are considered very positive and strongly confirm the continuation of mineralization through the west portion of the Saddle Zone and into the area under the West pit.
West Pit Extension
Drilling in the east portion of the Saddle Zone included nine holes (4,971 m) and targeted areas along the DMT west of the West Pit Reserve between surface and 400 m below.
Significant results from the drilling include: 2.19 gpt over 39.8 m, including 21.32 gpt over 2.7 m and 0.84 gpt over 21.0 m from hole DLM-20-048B, 2.67 gpt over 21.0 m, including 17.67 gpt over 2.0 m and 1.57 gpt over 38.0 m from hole DLM-20-045, 0.66 gpt over 90.0 m, 47.53 gpt over 2.0 m and 0.69 gpt over 15.0 m from hole DLM-20-023; and 1.19 gpt over 23.8 m from hole DLM-20-038B. These holes targeted the DMT west of the current mineral reserve between 200 and 400 m level and provide strong confirmation that DMT and associated mineralization continues for at least another 200 m in this direction and remains open for testing.
Additional significant results include: 1.44 gpt over 42.0 m from hole DLM-20-042, 1.79 gpt over 39.0 m, including 12.23 gpt over 3.0 m from hole DLM-20-032, 0.93 gpt over 19.3 m from DLM-20 – 31 and 0.81 gpt over 18.0 m from hole DLM-20-029A. These holes targeted the westward extension between surface and 200 m below and demonstrate the continuity of mineralization in the new westward extension to surface.
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. The work also suggests that mineralization within the corridor is very similar to that found in the West and Main pits and is hosted mainly by broad zones containing variable amounts of quartz and pyrite, which are controlled mainly by east-west trending, moderately north dipping folds and shear structures which plunge at a shallow angle to the west. Given results to date, the 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 is considered excellent.
Exploration work at Detour Lake is ongoing with eight drills current working, and on track to complete approximately 70,000 m by the end of 2020. The Company plans to increase the number of drills to between ten and twelve drills early in the new year.
The Company’s exploration programs at Detour Lake are conducted under the supervision of Eric Kallio, P.Geo., Senior Vice President, Exploration. Mr. Kallio, as well as Keith Green, P.Geo., Director, Exploration, Canada, and Steve Gray, P.Geo, Exploration Superintendent, Detour Lake Mine, are ‘qualified persons’ for the purpose of National Instrument 43-101, Standards of Disclosure for Mineral Projects, of the Canadian Securities Administrators, and have reviewed and approved the scientific and technical information in this news release.
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 best practices. Samples are logged and sampled in a secure facility at the Detour mine site and under supervision of Qualified Geologists. NQ sized core is sawn in half with one half of the core prepared for shipment, the other half of core retained for future assay verification. Preparations for shipment include; placing individual samples with corresponding sample tag into sealed plastic bags, which are in turn placed into labelled and zip tied rice bags, and subsequently placed onto pallets, shrink wrapped and couriered to ALS Laboratories in Timmins, Ontario by Manitoulin Transport. Sample preparation is completed by ALS Laboratories in Timmins then sent to their Vancouver Lab for analysis.
Assaying of the samples is completed using Fire Assay techniques with samples less than 10 grams per tonne being analyzed with Atomic Absorption (AA) and samples greater than 10 grams per tonne with gravimetric finish. Selected high grade samples are also analyzed using the screen metallics procedure. Internal laboratory checks conducted by ALS include the insertion of 1 blank, 2 certified reference standards and 3 duplicates for every 78 samples (per fusion furnace). ALS Laboratories are certified by the Standards Council of Canada (SCC) which conforms with ASB-RG Mineral Analysis Laboratory for the Accreditation of Mineral Analysis Testing Laboratories and CAN-P-4E ISO/IEC 17025 : General Requirements for the Competence of Testing and Calibration Laboratories.

Cautionary Note to U.S. Investors - Mineral Reserve and Resource Estimates
This press release has been prepared in accordance with the requirements of the securities laws in effect in Canada, which differ from the requirements of United States securities laws. The terms “mineral reserve”, “proven mineral reserve” and “probable mineral reserve” are Canadian mining terms as defined in accordance with Canadian National Instrument 43-101-Standards of Disclosure for Mineral Projects (“NI 43-101”) and the Canadian Institute of Mining, Metallurgy and Petroleum (the “CIM”)-CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended. These definitions differ from the definitions in SEC Industry Guide 7 under the United States Securities Act of 1993, as amended (the “Securities Act”).
The SEC has adopted amendments to its disclosure rules to modernize the mineral property disclosure requirements for issuers whose securities are registered with the SEC under the Securities Exchange Act of 1934 (“Exchange Act”). These amendments became effective February 25, 2019 (the “SEC Modernization Rules”) and, following a two-year transition period, the SEC Modernization Rules will replace the historical property disclosure requirements for mining registrants that were included in SEC Industry Guide 7. Following the transition period, as a foreign private issuer that files its annual report on Form 40-F with the SEC pursuant to the multi-jurisdictional disclosure system, the Company is not required to provide disclosure on its mineral properties under the SEC Modernization Rules and will continue to provide disclosure under NI 43-101 and the CIM Definition Standards. If the Company ceases to be a foreign private issuer or loses its eligibility to file its annual report on Form 40-F pursuant to the multi-jurisdictional disclosure system, then the Company will be subject to the SEC Modernization Rules which differ from the requirements of NI 43-101 and the CIM Definition Standards. The SEC Modernization Rules include the adoption of terms describing mineral reserves and mineral resources that are “substantially similar” to the corresponding terms under the CIM Definition Standards. As a result of the adoption of the SEC Modernization Rules, the SEC now recognizes estimates of “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources”. In addition, the SEC has amended its definitions of “proven mineral reserves” and “probable mineral reserves” to be “substantially similar” to the corresponding CIM Definitions. U.S. investors are cautioned that while the above terms are “substantially similar” to CIM Definitions, there are differences in the definitions under the SEC Modernization Rules and the CIM Definition Standards. Accordingly, there is no assurance any mineral reserves or mineral resources that the Company may report as “proven mineral reserves”, “probable mineral reserves”, “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources” under NI 43-101 would be the same had the Company prepared the reserve or resource estimates under the standards adopted under the SEC Modernization Rules.
U.S. investors are also cautioned that while the SEC will now recognize “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources”, investors should not assume that any part or all of the mineralization in these categories will ever be converted into a higher category of mineral resources or into mineral reserves. Mineralization described using these terms has a greater amount of uncertainty as to its existence and feasibility than mineralization that has been characterized as reserves. Accordingly, investors are cautioned not to assume that any measured mineral resources, indicated mineral resources, or inferred mineral resources that the Company reports are or will be economically or legally mineable. Further, “inferred mineral resources” have a greater amount of uncertainty as to their existence and as to whether they can be mined legally or economically. Therefore, U.S. investors are also cautioned not to assume that all or any part of the “inferred mineral resources” exist. Under Canadian securities laws, estimates of “inferred mineral resources” may not form the basis of feasibility or pre-feasibility studies, except in rare cases.
