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 underground drilling programs at the Fosterville Mine in Victoria, Australia. Underground drilling continues to target down-plunge extensions of Swan Mineral Reserves with results providing confirmation of the geological model and continuity of high-grade, visible-gold bearing mineralization on the Swan structure.
Results from 19 new drill holes, totaling 6,482 m, outside of the December 31, 2017 Measured and Indicated Mineral Resources in the Swan Zone continue to return intervals of exceptionally high grades with visible gold. The drilling demonstrates that high-grade, visible-gold bearing quartz veins extend at least 200 m down-plunge from current Mineral Reserves.
Tony Makuch, President and CEO of Kirkland Lake Gold, commented: “We are quickly establishing Fosterville as a new, world-class gold camp, with the new drill results at Swan being the latest indication that there is much more to be found in terms of Mineral Reserves and Mineral Resources. Today’s intercepts confirm earlier drill results that demonstrated strong continuity of high-grade, visible-gold bearing Swan mineralization over 100 m down plunge from existing Mineral Reserves. They also include the intersection of high-grade Swan mineralization an additional 100 m down plunge, creating a potential 200 m envelope of exceptionally high-grade mineralization over substantial widths, with visible gold, which will drive future Mineral Reserve growth. With the new results, we are increasingly confident that our upcoming December 31, 2018 Mineral Reserve and Mineral Resource estimates will include a considerable increase in Mineral Reserves in the Swan Zone and a higher overall average grade and increased Mineral Reserve base for the Fosterville Mine as a whole.
“In addition, there are many more targets to be explored at Fosterville, in the Lower Phoenix Gold System, as well as at Harrier South, Robbin’s Hill and through our regional Large Ore Deposit Exploration or LODE program. At Lower Phoenix South, we are following up on drilling earlier this year that intersected mineralization 750 m down plunge of the current Swan Mineral Resources. Work is also continuing to assess the new mineralized structure, called Cygnet, which runs parallel to Swan, and was first announced in July. We will also soon commence deep drilling from a new exploration drift at Harrier South, where we have seen a trend towards increasing grades with visible gold in quartz-carbonate veins at depth, comparable to the well documented progression to higher grades at Lower Phoenix. At Robbin’s Hill, we reported the intersection of visible-gold bearing quartz veins earlier in the year and have two surface drills working to further extend this highly-prospective mineralization, while a variety of exploration techniques are being used to explore multiple other targets in the surrounding area.”
Swan Mineralized Zone Drilling Program
Results from the ongoing underground resource drilling program at the Swan Zone continue to demonstrate high-grade continuity down plunge from current Mineral Reserves.
High-Grade, Visible-Gold Bearing Intercepts Include:
- 289 g/t Au over 7.45 m (ETW 6.0 m), including 2,857 g/t Au over 0.75m (ETW 0.6 m) in hole UDH2551;
- 155 g/t Au over 11.9 m (ETW 9.9 m), including 1,566 g/t Au over 1.1m (ETW 0.9 m) in UDH2584A;
- 423 g/t Au over 3.55 m (ETW 3.2 m), including 760 g/t Au over 1.95m (ETW 1.8 m) in UDH2555;
- 215 g/t Au over 7.2 m (ETW 5.9 m), including 846 g/t Au over 1.55m (ETW 1.3 m) in UDH2590; and
- 353 g/t Au over 4.0 m (ETW 3.4 m), including 3,740 g/t Au over 0.35m (ETW 0.3 m) in UDH2552.
All drill results are presented in Table 1 and all drill collars are listed in Table 2.
Since the July 31, 2018 Kirkland Lake Gold News Release, underground diamond drilling in the Swan Zone has continued to return encouraging results down-plunge from current Mineral Reserves (Figure 1). Reported drill results are from 19 holes (6,482 m), of which 12 contain visible-gold mineralization with nine intervals of greater than 100 gram-metres and five intervals of greater than 1,000 gram-metres (i.e. gold grade x estimated true width) (Figure 2). All reported drill results are outside the December 31, 2017 Measured and Indicated Mineral Resources and highlight the continued significant Mineral Reserve growth potential of Swan.
Continued infill drilling into the December 31, 2017 Inferred Swan Mineral Resource has confirmed the strong continuity of high-grade, visible-gold bearing mineralization to a distance of up to 100 m down-plunge of Mineral Reserves. Two 1,000 gram-metre intercepts, 155 g/t Au over 11.9 m (ETW 9.9 m) from UDH2584A and 289 g/t Au over 7.45 m (ETW 6.0 m) from UDH2551, are located 100 m and 80 m down plunge from Mineral Reserves, respectively.
Previously drilling identified high-grade (>30 gram-metres), visible-gold bearing mineralization down plunge to 6230mN in hole UDE158 (November 7, 2017 Kirkland Lake Gold News Release). The intercept from UDH2494 of 83.1 g/t Au over 8.6 m (ETW 6.8 m), released today, demonstrates that exceptionally high-grade, visible-gold bearing mineralization (>100 gram‑metres) extends at least 200 m down-plunge of Mineral Reserves to the 6175mN northing and remains open for further extension.
Swan Footwall Splay
Infill drilling and ongoing interpretation of Swan has identified a mineralized footwall splay fault, named the Swan Footwall Splay (Figure 3). The fault emanates from and branches off the Swan Fault at approximately 6400mN and 4000mRL. The interpreted synthetic fault dips marginally steeper than the Swan structure at approximately 50° and has been defined down to the 3825mRL at a maximum separation distance of 20 m from the Swan Fault. Gold grades are highest on this structure immediately footwall to the Swan Fault.
Key Gold Intercepts:
- 24.0 g/t Au(1) over 2.6 m (ETW 2.2 m) in hole UDH2555; and
- 8.1 g/t Au over 3.5 m (ETW 3.1 m) in hole UDH2552
(1) Visible gold drill intercept
Over the remainder of 2018, infill drilling from the Phoenix 4190 m drill platform will continue to target the December 31, 2017 Inferred Swan Mineral Resource down plunge of Mineral Reserves. It is anticipated that drill results will be returned from intercepts spaced at a nominal 25m x 25m separation to an approximate depth of 3900mRL and northing 6200mN on the Swan structure. This drill coverage is expected to be sufficient to support conversion to an Indicated Mineral Resource category and enable a Mineral Reserve evaluation to be completed in time for inclusion in the December 31, 2018 Mineral Reserve and Mineral Resource estimates.

Drilling and Underground Sampling Assay QAQC
Kirkland 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 electronic multi-shot cameras.
Sampling consisted of diamond drill core that was either full core or half core sampled. Half 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 reference 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 visible-gold or considered likely to contain visible-gold were separated from sulfide gold samples and dispatched independently for assaying. At the laboratory “visible-gold” 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.
Assay results are based on 25-gram charge fire assays. Mean grades are calculated using a variable lower grade cut-off (generally 2 g/t Au) and maximum 2m 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.
All samples were assayed at On Site Laboratories, an independent laboratory in Bendigo, Victoria. The facility is registered ISO 9001:2008 (CERT-C33510).

Although the Company has attempted to identify key factors that could cause actual results to differ materially, there may be other factors that cause unanticipated and unintended results. There can be no assurance that such statements will prove to be accurate as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking statements.
Cautionary Note to U.S. Investors - Mineral Reserve and Resource Estimates
All resource and reserve estimates included in this news release or documents referenced in this news release have been prepared 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 (the "CIM Standards"). 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.
