Other key developments during Q2 2018, include:

• Significant exploration success
  • Fosterville: High-grade, visible-gold bearing quartz veins intersected at Robbin’s Hill, 3.8 km from Fosterville Mine, highlighting the potential to identify new areas of high-grade gold mineralization
  • Macassa: Underground in-fill drilling intersects high-grade mineralization within and outside existing Mineral Resources of the South Mine Complex in support of future growth in Mineral Resources and Mineral Reserves
  • Northern Territory: High-grade, visible-gold bearing mineralization extended to 1,000 metres below surface at Union Reefs, identifying a potential new source of gold production
  • Taylor: High-grade mineralization intersected up to 2.9 km east of Shaft Deposit, new gold system discovered below the West Porphyry Deposit extended by 150 metres to depth.
• Strong cash and cash flow
  • Cash and cash equivalents increased $43 million or 16% during Q2 2018, to approximately $318 million at June 30, 2018. Factors affecting cash included continued strong operating cash flow, the weighting of capital expenditures to the second half of 2018 (“H2 2018”), the release of approximately $20 million of previously-restricted cash (reflecting changes to security requirements related to rehabilitation performance guarantees) and the use of $15.0 million (C$20.0 million) of cash to acquire four million common shares of Novo Resources Corp.
  • On May 2, 2018, the Company reported strong Q1 2018 net earnings of $53.8 million ($0.25/share), cash flow from operating activities of $89.6 million and free cash flow of $50.2 million.
• Continued focus on shareholder returns
  • Quarterly dividend of C$0.02/share paid on April 13, 2018, with an increase to C$0.03/share announced effective for Q2 2018 dividend payable on July 13, 2018
  • Common share price increased 40% in Q2 2018 (44% year to date), closing on Friday, June 29, 2018 at C$27.84 on the TSX (C$29.20 per share as at July 9, 2018).

Tony Makuch, President and Chief Executive Officer of Kirkland Lake Gold, commented: “We had a strong second quarter, achieving record quarterly production at Macassa and a record month in June at Fosterville. Average grades at both mines were above expected levels. Contributing to Fosterville’s strong results was higher than planned mining in areas close to the contact of the Eagle and Swan zones, where we encountered greater widths and higher average grades than were anticipated. At Macassa, production on the 5700 Level, a relatively new area of mining, continued to outperform on grade, as they did during the first quarter of the year. We will be mining in and around this area throughout the balance of 2018. Based on our solid first-half results, and expectations for H2 2018, we are very much on track to achieve our consolidated production guidance for 2018 of more than 620,000 ounces.”

Review of Operating Mines

Fosterville

The Fosterville Mine produced 77,462 ounces in Q2 2018, based on processing 121,342 tonnes at an average grade of 20.6 g/t and average mill recoveries of 96.2%. A key driver of the strong quarterly results in Q2 2018 was record monthly production in June of 31,710 ounces, which resulted from processing 33,296 tonnes at an average grade of 30.4 g/t and average recoveries of 97.5%. Q2 2018 production compared to production of 77,069 ounces in Q2 2017, when the mine processed 147,486 tonnes at an average grade of 17.2 g/t and average recoveries of 94.7%. Production in Q2 2018 increased 21% from 63,843 ounces in Q1 2018, reflecting a 23% increase in the average grade. The growth from the previous quarter largely reflected increased mining activity in parts of the Eagle Zone located close to the contact with the Swan Zone. Average widths and grades in these areas have exceeded expectations. In addition, the Company also processed a small amount of development material from the Swan Zone during Q2 2018, which also returned higher than expected average grades.

Production at Fosterville in H1 2018 totaled 141,305 ounces, a 15% increase from H1 2017. H1 2018 production resulted from processing 245,011 tonnes at an average grade of 18.7 g/t and average recoveries of 96.0%, which compared to processing 285,273 tonnes at an average grade of 14.2 g/t and average recoveries of 94.3% in H1 2017. The 32% increase in the average grade compared to H1 2017 mainly resulted from the continued transition to mining deeper, higher-grade stopes, consistent with the trend towards higher grades at depth at Fosterville. 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. The Company continues to target initial production from a second mining front, in the Harrier System, near the end of 2018.

Following completion of H1 2018, Fosterville was on track to achieve the mine’s full-year 2018 production guidance of 260,000 – 300,000 ounces.

Macassa

The Macassa Mine achieved record quarter production in Q2 2018 of 60,571 ounces based on 89,781 tonnes milled at an average grade of 21.5 g/t and average mill recoveries of 97.7%. Q2 2018 production was 33% higher than the 45,699 ounces produced in Q2 2017, when 105,084 tonnes were processed at an average grade of 13.9 g/t. The increase from the same quarter in 2017 resulted from a 55% improvement in the average grade, largely reflecting mining higher-grade stopes, favourable grade reconciliations in Q2 2018 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 South Mine Complex. In addition, all tonnes processed in Q2 2018 related to mine production, whereas 15,083 tonnes of the 105,084 tonnes processed in Q2 2017 were drawn from low-grade stockpiles and had an averaged grade of 1.4 g/t. The grade of the 90,001 tonnes of mine production processed in Q2 2017 averaged 16.0 g/t. Q2 2018 production at Macassa was 12% higher than the previous quarterly production record at Macassa of 54,038 ounces in Q1 2018, when a total of 86,661 tonnes were processed (all from mine production) at an average grade of 19.9 g/t and average recoveries of 97.6%.

Production at Macassa in H1 2018 totaled 114,609 ounces, a 21% increase from H1 2017. H1 2018 production resulted from processing 176,442 tonnes at an average grade of 20.5 g/t and average recoveries of 97.7%. All tonnes processed in H1 2018 were from mine production. In H1 2017, a total of 196,544 tonnes were processed at an average grade of 15.4 g/t. Of tonnes processed in H1 2017, 175,547 tonnes related to mine production and averaged 17.0 g/t, with the remaining 20,997 tonnes being drawn from low-grade stockpiles and averaging 1.6 g/t. The 33% increase in the average grade from mine production, to 20.5 g/t in H1 2018 from 17.0 g/t grade in H1 2017, reflected mining higher-grade stopes, the impact of favourable grade reconciliations in H1 2018 and improved grade control practices.

At June 30, 2018, Macassa was well positioned to achieve the mine’s full-year 2018 production guidance of 215,000 – 225,000 ounces.

Holt

During Q2 2018, the Holt mine produced 13,712 ounces, which compared to 15,101 ounces in Q2 2017 and 16,675 ounces the previous quarter. Production in Q2 2018 resulted from processing 95,343 tonnes at an average grade of 4.8 g/t and average recoveries of 94.2%, which compared to processing 105,470 tonnes at an average grade of 4.7 g/t and average recoveries of 94.8% in Q2 2017 and 122,280 tonnes at an average grade of 4.5 g/t and average recoveries of 94.8% in Q1 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. The new guides will contribute to enhanced productivity from the shaft going forward. Average grades improved from both prior periods. Processing rates and ounces produced are expected to increase during the remaining quarters of 2018.

For H1 2018, Holt produced 30,387 ounces, largely unchanged from the 30,419 ounces produced in H1 2017 as a 3% increase in tonnes processed (217,623 tonnes in H1 2018 versus 211,099 tonnes in H1 2017) was offset by a slight reduction in the average grade (4.6 g/t in H1 2018 compared to 4.7 g/t the previous year).

The Company is targeting higher levels of production in H2 2018 compared to the first half of the year, and expects the Holt Mine to achieve the mine’s full-year 2018 production guidance of 65,000 – 75,000 ounces.

Taylor

Gold production from the Taylor Mine during Q2 2018 totaled 12,940 ounces, based on 99,711 tonnes processed at an average grade of 4.3 g/t and average recoveries of 94.1%. Q2 2018 production increased 6% from Q2 2017, when production totaled 12,218 ounces based on 67,520 tonnes processed at an average grade of 5.8 g/t and average recoveries of 96.2%. Production in Q2 2018 compared to production of 13,055 ounces the previous quarter when a total of 84,464 tonnes were processed at an average grade of 5.0 g/t and average recoveries of 95.5%. The average grade in Q2 2018 largely reflected mine sequencing with grades expected to increase over the balance of the year.

For H1 2018, Taylor produced 25,995 ounces from processing 184,175 tonnes at an average grade of 4.6 g/t and average recoveries of 94.8%. H1 2018 production compared to H1 2017 production of 23,160 ounces, which resulted from processing 130,809 tonnes at an average grade of 5.7 g/t and average recoveries of 96.5%.

Grades at the Taylor Mine are expected to improve in H2 2018 and the Company continues to target full-year 2018 production from Taylor of 60,000 – 70,000 ounces.
