TORONTO, April 25, 2018 (GLOBE NEWSWIRE) -- Kirkland Lake Gold Ltd. (“Kirkland Lake Gold” or the “Company”) (TSX:KL) (NYSE:KL) (ASX:KLA) is pleased to report new exploration drill results from surface and underground drilling at the Taylor mine (“Taylor”) in Northeast Ontario, and situated along the PDF. Recent drilling occurred at depth below both the East and West Porphyry deposits; at a prospective target area situated down-dip of the Shaft Deposit and east of the West Porphyry Deposit; and on strike to the east along the hanging wall of the PDF. The new drill results involve 60 holes for 26,257 m of surface drilling and 31 holes for 5,512 m of underground drilling, which were completed late in 2017 and early in 2018.

The drill intersections reported today provide significant results at all three of the Company’s key exploration targets at Taylor mine. At the West Porphyry Deposit, the results of surface drilling include a 150 m extension of the new high-grade gold zone first reported last December (see Kirkland Lake Gold News Release dated December 18, 2017). The zone has now been identified over an area between 350 m and 500 m below existing mining (780 m and 930 m below surface). In the gap area between the West Porphyry and Shaft deposits, multiple high-grade intersections highlight the potential for additional growth in Mineral Resources close to existing mine infrastructure. Drilling east along the PDF continued to intersect high-grade gold bearing quartz veins, with the furthest intersection now located 2.9 km east of the Shaft Deposit, on a new claim block acquired in 2017.  Previously, the furthest intersection had been 1.8 km east of the Shaft Deposit.

Tony Makuch, President and CEO of Kirkland Lake Gold commented: “Included in our plan to increase Kirkland Lake Gold’s annual production to a million ounces within 5 to 7 years is growth in both production levels and mine life at our Taylor mine. Today’s drill results are very encouraging, as they demonstrate the considerable growth potential that exists at multiple locations around our existing deposits at Taylor. In addition, we have achieved extensive and consistent success intersecting high-grade quartz veins along the PDF east of the Shaft Deposit. With our latest high-grade intersections 1.1 km, 1.3 km and 2.9 km east of the Shaft Deposit, future drilling will focus less on further expansion and more on drilling within this very large mineralized area to determine its full potential.  Our exploration program at Taylor is continuing with four surface drills and one underground drill in operation as we continue our work to grow the mine’s Mineral Resources and Mineral Reserves."

Surface Drilling Program

Surface drilling to date has focused primarily on targets east and south-west of the Shaft Deposit, where shallow dipping mineralized quartz veins situated in the hanging wall of the PDF have been intersected at multiple locations (see Figures 1 & 2).  The new results being reported include a total of 60 holes totaling 26,257 m of surface exploration. Results from this drilling support the Company’s view that mineralization at Taylor remains open at depth and along strike to the east and west.

Significant drill results from surface drill programs include:

• 8.9 g/t Au over 13.2 m in hole TA17-081 drilled approximately 900 m east of the Shaft Deposit
• 20.1 g/t Au over 6.3 m (7.1 g/t cut) and 25.0 g/t Au over 1.5 m in hole TA17-103 drilled approximately 1.1 km east of the Shaft Deposit
• 10.0 g/t Au over 5.9 m in hole TA17-130 drilled approximately 1.1 km east of the Shaft Deposit
• 4.3 g/t Au over 10.9 m in hole TA18-140 drilled approximately 1.3 km east of the Shaft Deposit
• 5.8 g/t Au over 7.8 m in hole TA18-143 drilled approximately 1.3 km east of the Shaft Deposit
• 205.8 g/t Au over 0.7 m in hole TA17-115 drilled approximately 1.1 km east of the Shaft Deposit
• 45.2 g/t Au over 2.4 m (21.8 cut) in hole TA18-099A drilled approximately 500 m below the mine workings in the West Porphyry Deposit
• 8.9 g/t Au over 3.6 m and 4.9 g/t Au over 3.3 m in hole TA17-110 drilled approximately 500 m east of the Shaft Deposit
• 7.9 g/t Au over 5.0 m in hole TA17-094W3 drilled approximately 500 m below the mine workings in the West Porphyry Deposit
• 2.9 g/t Au over 6.0 m and 38.0 g/t Au over 1.2 m in hole TA17-098 drilled approximately 2.9 km east of the Taylor mine.

Surface drilling by the Company on the Taylor property is actively testing for mineralized extensions along strike to the east of the Shaft Deposit and up dip and at depth below the West Porphyry Deposit. Drilling east of the Shaft Deposit continued to intersect high-grade gold mineralization along the PDF with hole TA17-130 intersecting 10.0 g/t Au over 5.9 m approximately 1.1 km east of the Shaft Deposit, and Hole TA18-143 intersecting 5.8 g/t Au over 7.8 m 1.3 km east of the Shaft Deposit. Scout level surface drilling in 2017 also identified new mineralization along strike and up to 2.9 km east of the Shaft Deposit with hole TA17-098 returning 2.9 g/t Au over 6.0 m and 38.0 g/t Au over 1.2 m. In addition, TA18-099A and TA17094W3 intersected 45.2 g/t Au over 2.4 m and 7.9 g/t Au over 5.0 m, respectively, 500 m below the current mine infrastructure. The drilling is testing multiple targets including the 1004, 1003 and GAP zones, and testing for other mineralized zones on the property. These recent assay intercepts confirm that mineral deposits at Taylor are part of a larger deeper mineralized system, which remains open both along strike and to depth.

Surface drilling is on-going with four drills and continues to following-up on the most recent high-grade results.

Underground Drilling

Recent underground exploration results from the 430 m level highlight the potential to add Mineral Resources below the current workings of the mine. This deep drilling program has been targeting the potential repetition of shallow dipping mineralized structures as found in the West Porphyry Deposit, in addition to the apparent westerly down-plunge extension of Shaft Deposit mineralization (see Figures 3 and 4). 

Highlights of the results include:

• 19.0 g/t Au over 6.1 m (13.0 g/t cut) containing numerous visible gold stringers, in hole T430-065
• 13.9 g/t Au over 1.1 m intersected in hole T430-039
• 13.5 g/t Au over 1.5 m intersected in hole T430-052.

Drilling from 430 Level continues to follow up on new mineralization located below the GAP zone in an area with limited drilling between the West Porphyry and Shaft deposits. Current intersections extend the mineralization approximately 100 m below the 430 m sub-level exploration drift. 

Taylor Mine Geology

The Taylor mine is located along the PDF, a major structural feature, striking roughly east-west, dipping to the south between 40° to 60° south and globally associated with gold mineralization. Geologically, the Taylor property can be generalized from south to north as 1) mafic volcanic rocks of the Vipond Formation, which are relatively undeformed and unaltered; 2) ultramafic and mafic volcanic rocks of the Hersey Lake Formation, which are increasingly deformed and carbonate-altered in the vicinity of structurally emplaced lenses of Porcupine sedimentary rocks and felsic to intermediate porphyritic intrusions; 3) Porcupine assemblage greywacke-siltstone, which are interpreted to represent the footwall of the PDF on the Taylor property and a structural unconformity with the older, overlying mafic and ultramafic assemblage. The entire sequence is crosscut by a swarm of northeast-striking Matachewan diabase dikes.

Known gold mineralization at Taylor is located within the PDF and is primarily associated with the Hersey Lake Formation. Four mineralized deposits have been identified over a strike length of 2 km. From east to west these are: the near surface Shaft Deposit, with gold mineralization associated with felsic intrusive dikes; the East and West Porphyry deposits, comprised of a system of stacked vein systems (e.g. 1004, 1003), with the gold mineralization associated with quartz veins developed on the margins of felsic intrusive, sedimentary and carbonate-altered mafic ultramafic rocks; and the near-surface Shoot Deposit, with gold mineralization hosted by argillaceous metasedimentary rocks within a package of carbonate-altered ultramafic rocks.  Gold commonly occurs as relatively coarse-sized free gold in quartz, but also occurs as finely disseminated particles, which may be intimately associated with sulphides both in quartz-carbonate veins and in surrounding altered host rocks.
