KIRKLAND LAKE GOLD INTERSECTS '04 BREAK MINERALIZATION; HIGHEST ELEVATION TO DATE AND WITHIN AN UNEXPLORED AREA OF THE MINE
Kirkland Lake Gold Inc. has provided an update on the underground exploration drilling program on the '04 break (to the east of shaft 3), at the company's Macassa mine complex. The drilling program returned significant intersections on the '04 as high as the minus 2,890 elevation, highest elevation in the history of the Macassa mine and within a large unexplored area of the mine.
Highlights:
- This intersection occurred at the minus 2,967 elevation and on the west side
of the Tegren cross fault ('04 West).
- Drill hole 34-666 returned 5.26 ounces per ton uncut (180.34
grams per tonne) or 2.53 ounces per ton cut (86.74 grams per tonne) over 6.2 feet
(1.9 metres) or 2.4 feet (0.7 metre) true width.
- This intersection occurred at the minus 2,890 elevation, highest to date in
the Macassa mine on the '04 and east of the Tegren cross fault ('04
East).
- Drill hole 34-668 returned 0.80 ounce per ton (27.43 grams per tonne) over a core length
of 7.9 feet (2.4 metres) or 4.4 feet (1.3 metres) true width.
George Ogilvie, president and chief executive officer, commented: "We are very happy to report exploration success on the '04 break mineralization. The drilling has identified mineralization on the highest level in the mine to date, and remains open further to the east.
"We will continue to follow up on this target, as well as expanding the known mineralization at the South mine complex to the south. We have four other past-producing dormant mines which have seen little to no exploratory work, and we believe warrant testing in the coming years.
"The company currently has a 14-year mine life based on the current level of resources and reserves, and with continued exploration success, we plan to be mining here for many years to come."
History of Macassa mine
Production at the Macassa mine began in 1933 and was centered on the Kirkland Lake Main break, called the Main break, which had been followed westward from the Toburn, Sylvanite, Wright Hargreaves, Lakeshore Teck Hughes and Kirkland Minerals properties.
In 1955 a new major break was discovered on the Macassa property termed the '04 break. Located 400 feet north of the Main break, the '04 has been the most important ore-related structure at Macassa since the 1980s and mined from the minus 3,800 level to the minus-7,000-foot levels. As there is a mere 400-foot differential between these two distinct breaks east of the Amikougami north-south fault, they are sometimes referred together as the '04-Main break.
'04 break drilling results
The current phase of the underground exploration program is being conducted from the 3,422 level incline. Mineralization is typical of the '04, comprising strong quartz veining with associated molybdenite, visible gold and tellurides. The mineralization generally dips 60 to 75 degrees to the south.
The Tegren cross fault is known throughout the Macassa mine. It is a late, postore strike-slip fault with a sinistral movement (east side to the north) of approximately 150 feet (45.7 metres) in this area of the mine.
- Drill hole 34-668 has intersected the 04 at the minus 2,890 elevation, 60 feet
(18.3 metres) east of the Tegren cross fault and assayed 0.80 ounce per ton (27.43
grams per tonne) over a core length of 7.9 feet (2.4 metres), or 4.4 feet (1.3
metres) true width. This intersection represents the highest elevation
to date on the '04.
- A paste-fill hole completed in 2005 intersected two quartz veins in the
unexplored area. The upper four-inch vein was mineralized with
considerable visible gold and tellurides and retained for display
purposes. The lower vein assayed 0.51 ounce per ton (17.5 grams per tonne) over a core length
of three feet (0.9 metre). These intersections underpin the exploration
potential in this area of the Macassa mine.
- Mining and exploration in this area of the '04 to date indicate a strike
length of 800 feet (243.8 metres), a vertical extent of 250 feet (76.2
metres) and remains open to the east and up dip.
- Mining commenced in this area late July, 2014. Additional development is
planned to facilitate mining and to provide access for additional
exploration.

Qualified person
The results of the company's underground diamond drilling program have been reviewed, verified (including sampling, analytical and test data) and compiled by the company's geological staff under the supervision of Stewart Carmichael, PGeo, manager of exploration. Mr. Stewart 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 this news release.
Quality assurance/quality control
The company has implemented a quality assurance and control program to ensure sampling and analysis of all exploration work is conducted in accordance with the best possible practices. The drill core is sawn in half with one-half of the core samples shipped to Swastika Laboratories in Swastika, Ont. The other half of the core is retained for future assay verification. Other QA/QC includes the insertion of blanks, and the regular reassaying of pulps and rejects at alternative certified labs. Gold analysis is conducted by fire assay using atomic absorption or gravimetric finish. The laboratory reassays at least 10 per cent of all samples and additional checks may be run on anomalous values.
