Tony Makuch, President and Chief Executive Officer of Kirkland Lake Gold, commented: “Q3 2018 was a record quarter for both Fosterville in Australia and our Canadian operations as a whole. At Fosterville, we commissioned a second gravity circuit during Q3 2018 and saw an immediate spike in production, with the Fosterville Mill processing over 18,000 ounces in the first week of the circuit’s operation. This spike can largely be attributed to the gravity circuit’s effectiveness in recovering gold previously contained in the recirculating load of the grinding circuit. We also mined and processed our first Swan Zone stope during the quarter, which contributed over 7,500 ounces of production at an average grade of close to 40 g/t, in line with target levels. Turning to our Canadian operations, record production across our three mines reflected strong results at Macassa, where Q3 2018 production was very much in line with target levels, our best quarter of production to date at Holt and a better production performance from Taylor Mine compared to the previous quarter. Heading into the final quarter of the year, we are very well positioned to achieve our improved 2018 consolidated production guidance of over 635,000 ounces.”

Q3 and YTD 2018 Production Results

Performance Against Full-Year 2018 Production Guidance

1) On August 1, 2018, the Company announced the following improvements to full-year 2018 production guidance: Consolidated production guidance was increased to more than 635,000 ounces from more than 620,000 ounces; Macassa’s production guidance was revised to 220,000 – 225,000 ounces from 215,000 – 225,000 ounces; Fosterville’s production guidance was revised to 275,000 – 300,000 ounces from 260,000 – 300,000 ounces.

YTD 2018 production totaled 492,484 ounces, an increase of 15% from 429,822 ounces for YTD 2017. Excluding production from mines currently on care and maintenance, total consolidated production of 492,437 ounces for YTD 2018 grew 20% from 408,953 ounces for YTD 2017. Based on year-to-date results as at September 30, 2018, the Company entered the fourth quarter of the year well positioned to achieve its improved full-year 2018 consolidated production guidance of more than 635,000 ounces, which was increased from more than 620,000 ounces on August 1, 2018 with the release of the Company’s Q2 2018 financial results.

Review of Operating Mines

Fosterville

The Fosterville Mine produced a record 90,618 ounces in Q3 2018, based on processing 113,101 tonnes at an average grade of 25.6 g/t and average mill recoveries of 97.5%. Q3 2018 production increased 47% from 61,535 ounces in Q3 2017, when the mine processed 143,326 tonnes at an average grade of 14.1 g/t and average recoveries of 94.7%. Production in Q3 2018 increased 17% from 77,462 ounces in Q2 2018, reflecting a 24% increase in the average grade. During Q2 2018, a total of 121,342 tonnes was processed at an average grade of 20.6 g/t and average recoveries of 96.2%. During Q3 2018, the Company commissioned a second gravity circuit at Fosterville, which resulted in a spike in production as gold previously contained in the recirculating load of the grinding circuit was recovered through the new gravity circuit. In addition, the first Swan Zone stope was mined and processed during the quarter, which contributed over 7,500 ounces of production at an average grade of close to 40 g/t, in line with target levels.

Production at Fosterville for YTD 2018 totaled 231,923 ounces, a 26% increase from 184,688 ounces for YTD 2017. YTD 2018 production resulted from processing 358,112 tonnes at an average grade of 20.9 g/t and average recoveries of 96.6%, which compared to processing 428,599 tonnes at an average grade of 14.2 g/t and average recoveries of 94.4% for YTD 2017. A 47% increase in the average grade compared to YTD 2017 mainly resulted from the continued transition to mining deeper, higher-grade stopes, which include quartz veins containing significant amounts of visible gold. The reduction in tonnes milled compared to the prior year reflected the mine’s focus on extracting high-grade stopes at depth within the Lower Phoenix System. Mined and processed tonnes are expected to increase in the latter half of 2019 as major capital projects are completed, including new ventilation, a paste-fill plant and capital and exploration development.

Macassa

The Macassa Mine produced 55,582 ounces in Q3 2018 based on processing 92,503 tonnes at an average grade of 19.2 g/t and average mill recoveries of 97.3%. Q3 2018 production was 15% higher than the 48,206 ounces produced in Q3 2017, when 93,391 tonnes were processed at an average grade of 16.5 g/t and average mill recoveries of 97.4%. The increase from the same quarter in 2017 resulted from a 16% improvement in the average grade, largely reflecting mining higher-grade stopes due to mine sequencing and the impact of improvements in grade control practices. The strong grade performance related mainly to stope production on or around the 5700-foot level, where mining commenced at the end of last year and which represents the deepest production recorded to date in the SMC. Q3 2018 production at Macassa compared to record quarterly production of 60,571 ounces in Q2 2018, when the mine processed 89,781 tonnes at an average grade of 21.5 g/t and average recoveries of 97.7%. The change from the previous quarter related to a higher average grade in Q2 2018, mainly reflecting the mining of higher-grade stopes and a greater impact from positive grade reconciliations during the previous quarter.

Production at Macassa for YTD 2018 totaled 170,190 ounces, a 19% increase from 142,628 ounces for YTD 2017. YTD 2018 production resulted from processing 268,945 tonnes at an average grade of 20.2 g/t and average recoveries of 97.5%. All tonnes processed in YTD 2018 were from mine production. For YTD 2017, a total of 289,935 tonnes were processed at an average grade of 15.7 g/t. Of tonnes processed for YTD 2017, 267,924 tonnes related to mine production and averaged 16.9 g/t, with the remaining 22,011 tonnes being drawn from low-grade stockpiles and averaging 1.6 g/t. The 20% increase in the average grade from mine production for YTD 2018 compared to the previous year resulted from mining higher-grade stopes deeper in the SMC during YTD 2018, as well as the impact of favourable grade reconciliations and improved grade control practices.

Holt

During Q3 2018, the Holt mine achieved record quarterly production of 20,609 ounces, a 21% increase from 16,995 ounces in Q3 2017 and 50% higher than 13,712 ounces the previous quarter. The increase in production from both prior periods resulted from a combination of higher tonnage and improved average grades. Production in Q3 2018 resulted from processing 135,849 tonnes at an average grade of 5.0 g/t and average recoveries of 95.0%, which compared to 124,394 tonnes being processed at an average grade of 4.5 g/t and average recoveries of 94.5% in Q3 2017 and 95,343 tonnes being processed at an average grade of 4.8 g/t and average recoveries of 94.2% in Q2 2018. During Q2 2018, the mine had a 21-day planned shutdown in order to replace approximately 700 guides on the Holt shaft, which impacted both tonnes processed and ounces produced for the quarter.

For YTD 2018, Holt produced 50,996 ounces, an 8% increase from 47,414 ounces for YTD 2017. The increase in production mainly reflected a 5% improvement in mill throughput, to 353,472 tonnes at and average grade of 4.7 g/t and average recoveries of 94.7%, which compared 335,493 tonnes processed at an average grade of 4.6 g/t and average recoveries of 94.7% for YTD 2017.

Taylor

Gold production from the Taylor Mine during Q3 2018 totaled 13,333 ounces, based on processing 94,092 tonnes at an average grade of 4.7 g/t and average recoveries of 94.3%. Q3 2018 production increased 20% from Q3 2017, when production totaled 11,066 ounces based on 71,897 tonnes processed at an average grade of 5.0 g/t and average recoveries of 95.5%. Production in Q3 2018 was 3% higher than the previous quarter, when a total of 99,711 tonnes were processed at an average grade of 4.3 g/t and average recoveries of 94.1%.

For YTD 2018, Taylor produced 39,328 ounces from processing 278,266 tonnes at an average grade of 4.7 g/t and average recoveries of 94.6%. YTD 2018 production compared to YTD 2017 production of 34,223 ounces, which resulted from processing 202,706 tonnes at an average grade of 5.5 g/t and average recoveries of 96.2%.
