TORONTO, Dec. 10, 2019 (GLOBE NEWSWIRE) — Kirkland Lake Gold Ltd. (“Kirkland Lake Gold” or the “Company”) (TSX:KL) (NYSE:KL) (ASX:KLA) today announced new high-grade results from the ongoing surface drilling at the Fosterville Mine in Victoria, Australia. Recent surface drilling targeting additional growth in Mineral Resources confirmed mineralization down-plunge of the existing Mineral Resource at Robbin’s Hill. In addition, surface infill drilling into current Mineral Resources continues to return high-grade results, with two intercepts containing VG, providing confirmation of the geological model. Drill results reported are from 66 holes (36,428 m) that targeted extension and infill of the Robbin’s Hill Mineral Resources. Drill results reported are post the December 2018 Mineral Resource and Mineral Reserve update (See Press Release dated February 21, 2019).Tony Makuch, President and CEO of Kirkland Lake Gold, commented: “For a long time, we’ve been saying that there could be more Fostervilles at Fosterville and, with today’s results, Robbin’s Hill has clearly emerged as a second potential mining front to provide feed to our Fosterville Mill. Based on current drilling, we have already identified a large mineralized system at Robbin’s Hill that we expect will support substantially higher levels of Mineral Resources and that remains open at depth and along strike. Most of our drilling has targeted areas 650 m from surface and higher. The level of VG in quartz that we’ve intersected in this area compares favourably to levels seen at the existing Fosterville Mine at similar elevations. The presence of VG in quartz and 500 m down-plunge extension of Robbin’s Hill mineralization, included in today’s results, highlight the potential for future discoveries of high-grade, VG-bearing zones at depth similar to Swan and Eagle at Fosterville’s Lower Phoenix system. Work is continuing at Robbin’s Hill with five surface drill rigs on site and plans currently being finalized for future underground development and drilling.”In addition to drilling and other exploration techniques, the Company is currently performing a 3D seismic survey covering an approximate 6 km2 in the north part of the Fosterville mining license. The geophysical survey is the first of its kind to be undertaken in Victoria for gold exploration and will provide a high-resolution 3D dataset to a depth of over one kilometre. The Company is optimistic that results of this detailed survey will assist in the definition of structural features and mineralized corridors which will aid the future exploration and development of the Robbin’s Hill area. Robbin’s Hill Drilling ProgramsDuring 2019, up to six surface diamond drills operated in the Robbin’s Hill area, primarily targeting gold mineralization along the west-dipping Curie Fault, one of the controlling structures for mineralization at Robbins’s Hill. Programs have included infill drilling within the existing Mineral Resource, and also extension and step out drilling along the Robbin’s Hill mineralization trend. Five surface drills continue to operate at Fosterville and are focused on Mineral Resource extension and other targets, and north along the Fosterville Fault zone mineralized trend (Figure 1 and Figure 2). Infill DrillingSince the December 2018 Fosterville Mineral Resource and Reserves update a total of 37 surface diamond infill holes for 16,677 m have been drilled into the Mineral Resource at Robbin’s Hill in 2019. The intent of infill drilling was to produce an approximate 50 m x 50 m spacing of drill intercepts, to assess continuity and tenor of mineralization, and provide data for potential upgrade of the Inferred Mineral Resource to an Indicated Mineral Resource category.Results from the ongoing infill drilling program, reaffirm the continuity of the mineralization within the Mineral Resource, and of the 37 infill holes, 11 returned results greater than 30 gram-metres, including two holes with VG (Figure 3). The VG occurs on the west-dipping Curie Fault, where it passes beneath an anticline closure, as shown in cross section 12,725mN (Figure 4). In the Curie structure, the two instances of VG present as fine disseminations in quartz, akin to examples of VG observed in the Swan orebody.Key VG and sulfide-gold bearing intercepts include:High-Grade visible-gold bearing Intercepts >80 gram-m:11.7 g/t Au(1) over 8.8 m (ETW 7.2 m), including 81.7 g/t Au(1) over 0.5 m (ETW 0.4 m) in hole RHD32124.5 g/t Au(1) over 3.7 m (ETW 3.4 m), including 82.3 g/t Au(1) over 1.0 m (ETW 0.9 m) in hole RHD334AVisible-gold drill interceptSulfide-gold bearing intercepts >30 gram-m:11.3 g/t Au over 11.1 m (ETW 10.1 m) in hole RHD33110.5 g/t Au over 9.2 m (ETW 5.5 m) in hole RHD3006.8 g/t Au over 11.1 m (ETW 9.0 m) in hole RHD3407.0 g/t Au over 6.3 m (ETW 6.0 m) in hole RHD3475.5 g/t Au over 8.8 m (ETW 7.8 m) in hole RHD3634.7 g/t Au over 10.7 m (ETW 9.1 m) in hole RHD3563.3 g/t Au over 18.6 m (ETW 17.1 m) in hole RHD3367.3 g/t Au over 5.0 m (ETW 4.9 m) in hole RHD3395.1 g/t Au over 11.9 m (ETW 6.1 m) in hole RHD302

Results from the drilling programs will provide new data for the end of year Mineral Resource update and Mineral Reserve studies.  Extension and Step-Out DrillingIn addition to the infill drilling, extension and step-out drilling was completed and consisted of 29 holes for 19,751 m, of which 27 holes were drilled to attain an approximate 100 m x 50 m spacing, with results to support modelling of down-plunge mineralization for Mineral Resource growth.Seven of the holes returned results greater than 20 gram-metres and include (Figure 3):6.5 g/t Au over 12.7 m (ETW 10.2 m) in hole RHD3806.4 g/t Au over 11.0 m (ETW 10.1 m) in hole RHD3838.2 g/t Au over 4.0 m (ETW 3.8 m) in hole RHD2886.3 g/t Au over 4.0 m (ETW 3.6 m) in hole RHD3255.5 g/t Au over 4.7 m (ETW 4.0 m) in hole RHD3333.7 g/t Au over 18.7 m (ETW 6.4 m) in hole RHD385A3.3 g/t Au over 11.5 m (ETW 9.1 m) in hole RHD385BComplementing the extension drilling program, two step-out holes were also drilled, approximately 500 m down-plunge of the Robbin’s Hill Mineral Resource. Very significantly, both holes returned over 45 gram-m intercepts.Key Gold Intercept:10.4 g/t Au over 5.5 m (ETW 4.5 m) in hole RHD3519.5 g/t Au over 4.9 m (ETW 4.8 m) in hole RHD370High-Resolution 3D Seismic SurveyThe Company is presently completing a high-resolution 3D Seismic survey in the northern part of the Fosterville Mining License over the Robbin’s Hill mineralization trend. The survey is the first of its kind to be undertaken in Victoria for gold exploration and will provide a high-resolution 3D dataset to a depth of over one kilometre for detailed planning of future of underground development. The survey area is approximately 6 km2 with data collection along 12.5 m spaced east‑west lines. Initial processing of the 3D seismic data is expected to be complete by April 2020.To view the figures accompanying the press release, please click on the following linksFigure 1.

Qualified PersonsTroy Fuller, MAIG, Director of Exploration, Australia, is a “Qualified Person” as such term is defined in National Instrument 43-101 and has reviewed and approved the technical information and data included in this News Release.For further information regarding the Company’s 2018 Mineral Reserves and Mineral Resources estimates for the Fosterville Gold Mine, please refer to the Company’s news release dated February 21, 2019 and the Technical Report entitled “Updated NI 43-101 Technical Report Fosterville Gold Mine In the State of Victoria, Australia” effective December 31, 2018.Drilling and Underground Sampling Assay QAQCKirkland Lake Gold has in place quality-control systems to ensure best practice in drilling, sampling and analysis of drill core. All diamond drill hole collars (Table 2) are accurately surveyed using a Leica TS16 Total Station instrument and down-hole deviations are measured by either electronic gyro or single-shot instruments.Sampling consisted of NQ2 diamond drill core that was half-core sampled. Drill core samples were cut longitudinally in half with a diamond saw; one-half of the drill core was sent to an independent laboratory for analysis and the other drill core half retained for reference. Sample pulps are returned from the assay laboratory for storage and future geological or metallurgical studies. Drill core sample intervals vary between 0.3 and 1.2m in length and were determined from logging of sulfide and visible gold to geological boundaries.Samples containing VG or considered likely to contain VG were separated from sulfide gold samples and dispatched independently for assaying. At the laboratory “VG” jobs were processed through a single pulverizer and material barren of gold (‘quartz wash’) was crushed before and after each sample to minimize the potential for gold to contaminate successive samples.Assays are either based on 25-gram or 40-gram charge fire assay. Mean grades are calculated using a variable lower grade cut-off (generally 2 g/t Au) and maximum 2 m internal dilution. No upper gold grade cut is applied to the data. However, during future Mineral Resource studies the requirement for assay top cutting will be assessed.The majority of samples were assayed at On Site Laboratories, an independent laboratory in Bendigo, Victoria. The facility is registered ISO 9001:2008 (CERT-C33510). Some samples were assayed at Bureau Veritas, Adelaide. This facility is registered ISO 9001 : 2015 (CERT RN – 44 100 160145) and NATA accredited (1526).About Kirkland Lake Gold Ltd.Kirkland Lake Gold Ltd. is a growing gold producer operating in Canada and Australia that produced 723,701 ounces in 2018 and is on track to achieve significant production growth over the next three years, including target production of 950,000 – 1,000,000 ounces in 2019, 930,000 – 1,010,000 ounces in 2020 and 995,000 – 1,055,000 ounces in 2021.

NI 43-101 is a rule developed by the Canadian Securities Administrators, which established standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. The terms “mineral reserve”, “proven mineral reserve” and “probable mineral reserve” are Canadian mining terms as defined in accordance with NI 43-101 and the CIM Standards. These definitions differ materially from the definitions in SEC Industry Guide 7 (“SEC Industry Guide 7”) under the United States Securities Act of 1933, as amended, and the Exchange Act.In addition, the terms “mineral resource”, “measured mineral resource”, “indicated mineral resource” and “inferred mineral resource” are defined in and required to be disclosed by NI 43-101 and the CIM Standards; however, these terms are not defined terms under SEC Industry Guide 7 and are normally not permitted to be used in reports and registration statements filed with the U.S. Securities and Exchange Commission (the “SEC”). Investors are cautioned not to assume that all or any part of mineral deposits in these categories will ever be converted into reserves. “Inferred mineral resources” have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, except in very limited circumstances. Investors are cautioned not to assume that all or any part of a mineral resource exists, will ever be converted into a mineral reserve or is or will ever be economically or legally mineable or recovered.FOR FURTHER INFORMATION PLEASE CONTACTAnthony Makuch, President, Chief Executive Officer & Director
