TORONTO, July 05, 2018 (GLOBE NEWSWIRE) -- Kirkland Lake Gold Ltd. (“Kirkland Lake Gold” or the “Company”) (TSX:KL) (NYSE:KL) (ASX:KLA) today reported new high-grade drill intersections from underground exploration drilling within the SMC at the Macassa Mine, Kirkland Lake, Ontario. The new results involve 20 holes for 7,560 m of underground drilling from the east exploration drift on the 5300-foot level (“5300 Level”). Underground drilling from the 5300 Level will continue throughout the remainder of 2018.

The new high-grade intersections are situated within the 259 m eastern extension of the SMC, first reported in June 2017 (see Kirkland Lake Gold News Release dated June 28, 2017). The new intersections result from a continuation of the 2018 infill drilling program, with previous results reported in April 2018 (see Kirkland Lake Gold News Release dated April 27, 2018). The results will support further Mineral Resource expansion, as all but two of the intersections are located outside of the existing Mineral Resource blocks. Of particular significance, the new results include high-grade intersections within Footwall veins 78 m to the east of existing Mineral Resources within the SMC. In addition, the results have identified a high-potential area within the eastern extension of the SMC, which includes high grades and true widths well in excess of those normally seen in the area.  The intersections reported today are located approximately 560 m south-southeast of the location for the new #4 Shaft, with Phase 1 targeted for completion early in 2022. By comparison, these intersections are approximately 2.1 km east of the current production shaft (the #3 Shaft).  

Tony Makuch, President and Chief Executive Officer of Kirkland Lake Gold, commented: “We continue to report encouraging drill results to the east and southeast of existing resources within the SMC. The new drill results increase our confidence that, going forward, we will see continued solid resource growth within the SMC mineralization, and also achieve high levels of resource conversion, leading to higher levels of Mineral Reserves. In 2017, we achieved substantial growth in Mineral Resources, increasing Measured and Indicated Resources by 58% (to 2.1 million ounces at an average grade of 17.1 g/t) and Inferred Resources by 48% (to 1.4 million ounces at an average grade of 22.2 g/t) compared to the prior year.  Through ongoing drilling, we are now poised to convert a high level of these resources, adding to our already large base of Mineral Reserves (2.03 million ounces at 21.0 g/t).  The large reserve and resource base at Macassa, as well as the considerable potential to identify new ounces through continued drilling success, was a key consideration in our decision to move forward with our #4 Shaft. Exploration work is continuing at the mine, with three underground drills in operation to further explore for Mineral Resource conversion and expansion opportunities in the SMC.”

Underground Drilling Program Defining, Upgrading and Expanding Mineral Resource Areas

Recent drilling conducted from the easternmost drill stations on the 5300 Level concentrated on follow up drilling in the eastern extension area first detailed in June 2017 and was a continuation of drilling reported in April 2018 (see Kirkland Lake Gold News Release dated April 27, 2018).  

The mineralization intersected with the new drill results is consistent with the SMC, striking east-west in the geology grid with dips between 17 and 30 degrees south. The dominant mineral present appears to be gold-bearing telluride calaverite, with visible gold also commonly being observed.  

A high-grade area with greater than average widths has been defined within the SMC mineralized envelope with a strike length of approximately 73 m and a dip component of 45 m. Within this area, drilling has shown, on average, grades >= 30 g/t and true widths >= 3.0 m.  Recent drill holes of note in this area include: 53-3453 (34.6 g/t over 3.7 m true width), 53-3455 (38.4 g/t over 3.9 m true width), 53-3466 (65.5 g/t over 3.6 m true width), and 53-3505 (36.3 g/t over 4.2 m true width). The mineralization remains open to the east and is bound to the south by the Amalgamated Break. Considered a potential feeder structure for the SMC, the Amalgamated Break has undergone significant post-ore movement.

Underground Development Now Advancing West Leg

As reported in the News Release dated April 27, 2018, underground development on 5300 Level will include a 152-m drift and drill bay extension to the west. To date, this drift has advanced 68 m. Exploration at this location will concentrate on locating and defining Mineral Resources, which could be developed in the short term. While this development is underway, one of the exploration drills on 5300 Level will be re-located to the recently completed far east drill bay to continue testing and expanding the SMC to the east. Subject to continued favourable results from this program, the 5300 Level east exploration drift may be extended an additional 152 m east.

Qualified Person

The Company’s exploration programs at Macassa are conducted under the supervision of Stewart Carmichael, P.Geo., Regional Exploration Manager. Mr. Carmichael is the ‘qualified person’ for the purpose of National Instrument 43-101, Standards of Disclosure for Mineral Projects, of the Canadian Securities Administrators, and has reviewed and approved the scientific and technical information in this news release.

QA/QC Controls

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. The drill core is sawn in half with one half of the core samples shipped to Swastika Laboratories in Swastika, Ontario. The other half of the core is retained for future assay verification. Other QA/QC includes the insertion of certified reference standards, blanks and the regular re-assaying of pulps and rejects at alternate certified labs. Gold analysis is conducted by fire assay using atomic absorption or gravimetric finish. The laboratory re-assays at least 10% of all samples and additional checks may be run on anomalous values.
