Tony Makuch, President and Chief Executive Officer of Kirkland Lake Gold, commented: “During Q3 2018, our team turned in a strong performance and our mines continued to show their quality and ability to generate profitability and cash flow. Based on our performance year to date, we have been able to announce significant improvements to our 2018 consolidated production and unit cost guidance for a second time during the year. In addition, Q3 2018 provided a clear demonstration of our company’s ability to internally fund the growth projects needed to reach our goal of a million ounces per year of production. We generated over $50 million of free cash flow during the quarter at the same time that gold prices declined and we ramped up growth capital expenditures. At Macassa, work on our #4 shaft project included sinking the shaft collar and completing the headframe foundation in preparation for the concrete work to establish the 215-foot headframe, which commenced in early October and was completed later in the month. We remain on track to commence full-face shaft sinking of the #4 shaft by the second quarter of next year. We also advanced the ventilation, paste-fill plant and water treatment projects at Fosterville during Q3 2018, which resulted in higher growth capital expenditures compared to the previous quarter. In addition, we installed and commissioned a new gravity circuit at the Fosterville Mill during Q3 2018 and have since seen our recovery of gravity gold increase to well over 50% of total ounces produced.

“Entering the fourth quarter, we are positioned for a strong finish to 2018. Our operations are poised to deliver another quarter of solid production, cost and financial results. We will also continue our exploration programs and anticipate releasing additional drill results before year end, building on the encouraging results we have already announced from Fosterville, Macassa, the Northern Territory and Taylor. While still finalizing our budgets, we can look ahead to 2019 as another year of strong results and progress, including higher levels of production, continued low unit costs and solid financial performance. We also expect additional growth in Mineral Reserves and Mineral Resources, particularly at Fosterville, and will continue to accelerate progress with our growth projects.”

Q3 2018 production of 180,155 ounces was a quarterly record, increasing 30% from 139,091 ounces in Q3 2017 and 9% from 164,685 ounces in Q2 2018. The increase in production was driven by Fosterville, which produced a record 90,618 ounces in Q3 2018, based on processing 113,101 tonnes at an average grade of 25.6 gram per tonne and average mill recoveries of 97.5%. Q3 2018 production increased 47% from 61,535 ounces in Q3 2017 and 17% from 77,462 ounces in Q2 2018. In early August 2018, a second gravity circuit was commissioned at Fosterville, which resulted in a spike in the flotation concentrate grade reflecting the recovery of coarse-grain gold from low velocity zones of the grinding circuit. Production from the Company’s Canadian operations in Q3 2018 was a record 89,537 ounces. Macassa produced 55,582 ounces, a 15% increase from 48,206 ounces in Q3 2017 and compared to record quarterly production of 60,571 ounces the previous quarter. Holt and Taylor produced 20,609 ounces and 13,333 ounces, respectively, in Q3 2018, representing increases of 21% and 20% from Q3 2017 and 50% and 3%, respectively, from Q2 2018.

Revenue

Revenue in Q3 2018 totaled $222.7 million, an increase of $46.0 or 26% from $176.7 million in Q3 2017. Compared to Q3 2017, higher gold sales in Q3 2018 increased revenue by $59.8 million, with a total of 184,517 ounces sold in Q3 2018 versus 137,908 ounces being sold in Q3 2017. The increase is gold sales was largely attributable to Fosterville, where ounces sold grew by 53%, to 96,539 ounces from 62,998 ounces in Q3 2017, driven by record quarterly production of 90,618 ounces in Q3 2018. Gold sales at Macassa increased 22%, to 54,103 ounces from 44,456 ounces in Q3 2017, while ounces sold at the Holt and Taylor mines increased 24% and 18%, to 20,212 and 13,655 ounces, respectively. Partially offsetting the favourable impact of higher gold sales was a $78 per ounce or 6% decline in the average realized gold price per ounce, to $1,204 in Q3 2018 from $1,282 in Q3 2017, which reduced revenue by $14.3 million in Q3 2018 compared to Q3 2017. There was also a $0.5 million favourable impact on revenue from foreign exchange rate changes year over year.

Q3 2018 revenue increased $8.0 million or 4% from $214.7 million in Q2 2018. A 12% increase in gold sales, from 164,305 ounces in Q2 2018 to 184,517 ounces in Q3 2018, had a $26.3 million favourable impact on revenue compared to the previous quarter. This favourable impact was largely offset by a $17.9 million negative impact on revenue from a 7% reduction in the average realized gold price per ounce ($1,204 in Q3 2018 versus $1,301 in Q2 2018). There was also a $0.4 million reduction related to foreign exchange rate changes.

Revenue for YTD 2018 totaled $635.6 million, an increase of $100.5 million or 19% from $535.1 million for the same period in 2017. Contributing to the $100.5 million increase in revenue was a $87.3 million favourable impact from a 16% increase in gold sales, to 496,585 ounces from 427,017 ounces for the same period in 2017. In addition, a $20 per ounce or 2% increase in the average realized gold price per ounce, to $1,275 for YTD 2018 versus $1,255 for YTD 2017, increased revenue by $10.0 million for YTD 2018 versus YTD 2017. There was also a $3.2 million favourable impact from changes to foreign exchange rates on YTD revenue year over year. The increase in gold sales for YTD 2018 mainly resulted from strong sales growth at both Fosterville and Macassa. Gold sales at Fosterville totaled 233,139 ounces, a 31% increase from 178,315 ounces for YTD 2017. At Macassa YTD 2018 gold sales totaled 170,191 ounces versus 143,254 ounces for the same period in 2017. The increases in gold sales at both Fosterville and Macassa reflected strong production growth at both mines due to significant improvement the average grades for YTD 2018 versus YTD 2017.

Earnings from Mine Operations

Earnings from mine operations in Q3 2018 totaled $115.3 million, an increase of $41.9 million or 57% from $73.4 million in Q3 2017 and $5.8 million or 5% higher than $109.5 million the previous quarter. The increase from the same period in 2017 mainly reflected strong revenue growth. Production costs in Q3 2018 totaled $64.9 million, compared to production costs of $66.5 million in Q3 2017, which included $5.8 million of production costs for the Northern Territory operations, which were placed on care and maintenance effective June 30, 2017. Depletion and depreciation costs in Q3 2018 totaled $36.0 million, which compared to $31.7 million in Q3 2017 as the impact of higher gold production was partially offset by a significant increase in the level of Mineral Reserves and Mineral Resources at the Company’s operations following the release of the Company’s December 31, 2017 Mineral Reserve and Mineral Resource estimates on February 20, 2018. Royalty expense in Q3 2018 totaled $6.6 million versus $5.1 million in Q3 2017, with the increase mainly reflecting higher sales volumes. The increase in earnings from mine operations from the previous quarter related to revenue growth as well as lower production costs, with the reduction in production costs mainly at Macassa, reflecting the increased use of long-hole stoping mining methods and reduced maintenance expenses. These favourable factors were partially offset by higher levels of depletion and depreciation expense and royalty costs in line with greater production and sales volumes during Q3 2018.

For YTD 2018, earnings from mine operations totaled $317.5 million, a $120.6 million or 61% increase from $196.9 million for the same period in 2017. The increase reflected revenue growth of 19%, as well as lower production costs and depletion and depreciation costs. Lower production costs for YTD 2018 reflected the inclusion of $37.4 million of production costs related to the Northern Territory operations in the first nine months of 2017. A $6.6 million reduction in depletion and depreciation expense resulted from the increase in Mineral Reserves and Mineral Resources included in the December 31, 2017 Mineral Reserve and Mineral Resource estimates. Royalty costs for YTD 2018 totaled $18.8 million compared to $15.2 million for YTD 2017, with the increase reflecting higher sales volumes in YTD 2018.

Unit Cost Performance (See Non-IFRS measures)

Operating cash costs per ounce sold averaged $351 in Q3 2018, a 27% improvement from $482 in Q3 2017 largely reflecting an 82% improvement in the average grade at Fosterville compared to the third quarter a year earlier. Operating cash costs per ounce sold at Fosterville were $189 per ounce, a 36% improvement from $295 per ounce in Q3 2017. At Macassa, operating cash costs per ounce in Q3 2018 averaged $439, a 16% improvement from $521 for the same period in 2017, with a 16% improvement in the average grade largely accounting for the lower operating cash costs per ounce. Compared to the previous quarter, operating cash costs per ounce sold improved 13% from $404 in Q2 2018, with the quarter-over-quarter improvement mainly reflecting the impact of a higher average grade at Fosterville on the mine’s operating cash costs. Fosterville’s operating cash costs per ounce sold in Q3 2018 was 21% better than the previous quarter ($239 in Q2 2018).

AISC per ounce sold in Q3 2018 averaged $645 compared $845 in Q3 2017, with the significant improvement largely resulting from the 27% improvement in operating cash costs per ounce sold compared to Q3 2017. Also contributing to the improvement were lower sustaining capital expenditures on a per ounce sold basis, reflecting higher sales volumes in Q3 2018 compared to the same period a year earlier. Sustaining capital expenditures totaled $41.4 million or $224 per ounce sold in Q3 2018, which compared to $38.3 million or $278 per ounce sold in Q3 2017. Q3 2018 AISC per ounce sold improved 15% from $757 the previous quarter. In addition to the improvement in operating cash costs per ounce sold, the increase related mainly to lower levels of sustaining capital expenditures, which in Q2 2018 totaled $44.1 million or $268 per ounce.

For YTD 2018, operating cash costs per ounce sold averaged $397, a 22% improvement from $508 for YTD 2017, with the improvement mainly reflecting higher average grades at Fosterville and Macassa. AISC per ounce sold for YTD 2018 averaged $738, 9% better than AISC per ounce sold of $811 for YTD 2017. Sustaining capital expenditures for YTD 2018 totaled $127.6 million or $257 per ounce sold, which compared to $96.1 million or $225 per ounce sold for YTD 2017. Higher sustaining capital expenditures were included in the Company’s 2018 budget and related mainly to planned investments at Fosterville intended to support multiple years of production, including extensive underground development to establish new sources of production and purchases of new mobile equipment.

Additional Expenses

Exploration and evaluation expenditures (expensed) in Q3 2018 were $20.3 million, 22% higher than $16.7 million in Q3 2017. The year-over-year increase reflected the Company’s significant commitment to organic growth through continued exploration success. Exploration and evaluation expenditures in Q3 2018 compared to $15.8 million in Q2 2018. Exploration and evaluation expenditures (expensed) for YTD 2018 totaled $52.8 million, a 45% increase from $36.4 million for YTD 2017. Exploration and evaluation expenditures for YTD 2018 included $44.8 million in Australia, including $26.1 million in the Northern Territory and $18.6 million at Fosterville, and $8.0 million in Canada, divided between Taylor and Macassa.

Corporate G&A expense (excluding share-based payments expense and transaction costs) totaled $5.6 million in Q3 2018, unchanged from Q3 2017 and compared to $5.8 million for the previous quarter. For YTD 2018, corporate G&A expense totaled $18.3 million versus $15.6 million for the same time in 2017. The level of corporate G&A expense for corporate YTD 2018 largely reflected the weighting of legal and audit fees and incentive compensation expense to the first half of the year.

Share based payment expense in Q3 2018 totaled $0.5 million, compared to $1.0 million in Q3 2017 and $1.6 million the previous quarter. YTD 2018 share based payment expense totaled $3.9 million versus $3.3 million for YTD 2017.

Other loss/income had a significant impact on the comparison of net earnings in Q3 2018 to Q3 2017 and Q2 2018. Other loss in Q3 2018 totaled $5.8 million compared to other income of $21.3 million in Q2 2017 and other income of $4.3 million the previous quarter. The main factor contributing to other loss in Q3 2018 was a $6.4 million pre-tax mark-to-market loss on the fair valuing of the Company’s common share purchase warrants, with most of the loss relating to the Company’s 14.0 million Novo warrants. Partially offsetting the impact of the mark-to-market loss were unrealized and realized foreign exchange gains of $0.6 million, mainly resulting from the Australian dollar weakening against the US dollar during the quarter. Q3 2017 other income of $21.3 million largely reflected a $19.5 million pre-tax mark-to-market gain on fair valuing the Company warrants. Other income for the previous quarter of $4.3 million mainly reflected unrealized and realized foreign exchange gains of $6.5 million, which was partially offset by a $2.7 million pre-tax mark-to-market loss on fairing valuing the Company’s warrants. For YTD 2018, other income totaled $3.9 million, as realized and unrealized foreign exchange gains of $11.0 million were only partially offset by a $7.3 million pre-tax market-to-market loss on the fair valuing of warrants. YTD 2017 other income of $22.0 million mainly related to a $19.7 million pre-tax mark-to-market gain on the fair valuing of warrants.

Finance costs in Q3 2018 totaled $0.7 million versus $2.3 million in Q3 2017 and $1.1 million in Q2 2018. The change in finance costs from Q3 2017 mainly related to the maturity of the Company’s C$62.1 million 7.5% unsecured convertible debentures ("7.5% convertible debentures") on December 31, 2017 (99% of the debentures were converted into Kirkland Lake Gold common shares). Finance costs in Q3 2017 included interest payments on the 7.5% convertible debentures prior to their maturity. The reduction in finance costs from the previous quarter was due to lower interest on finance leases and other bank charges. YTD 2018 finance costs totaled $2.5 million, which compared to $8.7 million for YTD 2017. The year-to-date reduction related mainly to interest payments in 2017 related to the 7.5% convertible debentures, as well as the Company’s C$56.8 million 6% convertible debentures, which matured and were repaid with existing cash on June 30, 2017.

Income tax expense in Q3 2018 included current income tax expense of $8.0 million and deferred income tax expense of $19.1 million. The deferred tax expense in Q3 2018 resulted from the utilization of $24.6 million of deferred tax assets to reduce current income tax expense, which was offset by $4.5 million of tax recovery. In Q3 2017, current income tax expense totaled $12.0 million, while deferred income tax expense totaled $8.3 million. For the previous quarter, the Company reported current income tax expense of $10.5 million and deferred tax expense of $18.1 million. The $18.1 million of deferred tax expense reflected the utilization of $16.3 million of deferred tax assets to reduce current income tax expense during Q2 2018. YTD 2018 current income tax expense totaled $23.7 million, while deferred tax expense totaled $53.9 million. Deferred income tax expense for YTD 2018 reflected the utilization of $53.3 million of deferred tax assets to reduce current income tax expense. Income tax expense for YTD 2017 included $31.4 million of current income tax expense as well as deferred income tax expense of $19.4 million.

Net Earnings in Q3 2018 total $55.9 million or $0.27 per basic share

Net earnings in Q3 2018 totaled $55.9 million ($0.27 per basic share), an increase of $12.2 million or 28% from $43.7 million ($0.21 per basic share) in Q3 2017. Net earnings in Q3 2018 were entirely from continuing operations. Net earnings in Q3 2017 included earnings from continuing operations of $45.5 million ($0.22 per basic share) and loss from discontinued operations of $1.7 million ($0.01 per basic share), related to the Company’s Stawell Mine, which was placed on care and maintenance in December 2016 and sold on December 21, 2017. The 23% increase in net earnings in Q3 2018 compared to earnings from continuing operations in Q3 2017, mainly resulted from the impact of a $46.0 million or 26% increase in revenue, due to higher gold sales, which more than offset a reduction in the average realized price. Also contributing to the increase were lower finance costs and care and maintenance expense. Partially offsetting these favourable factors was other loss of $5.8 million in Q3 2018 versus other income of $21.3 million in Q3 2017, with the $27.0 million variance mainly related to fair valuing the Company’s warrants in both periods. The Company also had higher depletion and depreciation expense in Q3 2018 compared to Q3 2017, reflecting higher production volumes, and an increase in exploration and evaluation expense, consistent with the Company’s ongoing commitment to organic growth through exploration success.

Q3 2018 net earnings compared to net earnings for the previous quarter of $61.5 million ($0.29 per basic share). As with Q3 2018 net earnings, Q2 2018 net earnings were entirely from continuing operations. The comparison of net earnings in Q3 2018 to Q2 2018 was significantly influenced by the change in the average realized gold price, with the $97 per ounce or 7% reduction quarter over quarter having a negative impact of $17.8 million on the Company’s revenue and largely offsetting the favourable impact of higher gold sales. Also contributing to the change in net earnings in Q3 2018 versus Q2 2018 was the Q3 2018 other loss of $5.8 million, which compared to other income of $4.3 million in Q2 2018, with the latter mainly due to unrealized and realized foreign exchange gains. The Company also recorded an increase in exploration and evaluation expense as well as depletion and depreciation costs in Q3 2018 compared to the previous quarter.

Net earnings for YTD 2018 totaled $167.4 million ($0.79 per basic share), an increase of $76.0 million or 83% from net earnings of $91.4 million ($0.44 per basic share) for YTD 2017. Net earnings for YTD 2018 were entirely from continuing operations, whereas net earnings for YTD 2017 included earnings from continuing operations of $99.2 million ($0.48 per basic share) and loss from discontinued operations of $7.8 million ($0.04 per basic share) related to the Company’s Stawell Mine. The increase in net earnings compared to YTD 2017 earnings from continuing operations reflected a $100.5 million or 19% increase in revenue, due to both higher volumes and realized gold prices. Also contributing to the increase in net earnings from continuing operations were lower production costs, reduced depletion and depreciation expense, as well as reductions in care and maintenance and finance costs. Partially offsetting these factors were lower other income, increased exploration and evaluation expense and higher corporate G&A expense.

Adjusted net earnings (Non-IFRS) in Q3 2018 total $60.6 million or $0.29 per basic share

The Company’s adjusted net earnings for Q3 2018 totaled $60.6 million ($0.29 per basic share), which compared to adjusted net earnings of $35.4 million ($0.17 per basic share) in Q3 2017. The difference between adjusted net earnings and net earnings in Q3 2018 mainly reflected the exclusion of a $6.4 million pre-tax mark-to-market loss ($4.7 million on an after-tax basis) on the fair valuing the Company’s warrants. The difference between adjusted net earnings and net earnings in Q3 2017 related to the exclusion from adjusted net earnings of $14.1 million of pre-tax mark-to-market gains ($10.4 million on an after-tax basis) on the fair valuing of the Company’s warrants, as well as the exclusion of a $1.7 million loss from discontinued operations and severance payments made during the quarter of $0.4 million ($0.3 million on an after-tax basis).

Adjusted net earnings in Q3 2018 compared adjusted net earnings in Q2 2018 of $63.4 million ($0.30 per basic share). The difference between adjusted net earnings and net earnings in Q2 2018 mainly reflected the exclusion of a $2.7 million pre-tax mark-to-market loss ($2.0 million on an after-tax basis) on fair valuing the Company’s warrants from adjusted net earnings.

For YTD 2018, adjusted net earnings totaled $176.6 million ($0.84 per basic share), which compared to adjusted net earnings of $92.0 million ($0.44 per basic share) for YTD 2017. The difference between adjusted net earnings and net earnings for YTD 2018 reflected the exclusion from adjusted net earnings of the $7.3 million pre-tax mark-to-market loss ($5.4 million on an after-tax basis) related to fair valuing the Company’s warrants, as well as $5.4 million related to pre-tax purchase price allocation adjustments on inventories ($3.8 million after tax). The difference between adjusted net earnings for YTD 2017 and net earnings for the same period mainly resulted from the exclusion of $14.1 million of pre-tax gains ($10.4 million after tax) related to fair valuing the Company’s warrants, loss from discontinued operations of $7.8 million (after-tax), $2.6 million of pre-tax purchase-price allocation adjustments on inventories ($1.8 million on an after-tax basis), $1.5 million of pre-tax severance payments ($1.1 million on an after-tax basis) and $0.4 million ($0.3 million on an after-tax basis) of transaction costs related to acquisitions in 2016.

Q3 2018 net cash provided by operating activities of continuing operations of $128.4 million, free cash flow (Non-IFRS) totals $52.2 million

In the Company’s Q2 2018 MD&A and condensed consolidated financial statements, issued on August 1, 2018, reported cash totaled $318.4 million and included the release of $19.8 million of previously-restricted cash related to security requirements for rehabilitation performance guarantees in Australia. The Company’s Q3 2018 MD&A, as well as the condensed consolidated financial statements for the three and nine months ended September 30, 2018, report the $20.3 million (revised amount reflects foreign exchange and other items) as restricted cash for the full nine months of YTD 2018, recognizing that the amount continues to be required as collateral for letters of credit related to rehabilitation performance guarantees. The Company is currently considering other forms of collateral and, should they be obtained, would be in a position to release the $20.3 million from restricted cash. As a result, cash at June 30, 2018 is reported as $298.5 million in the Company’s Q3 2018 MD&A and the condensed consolidated interim financial statements for the three and nine months ended September 30, 2018.

Cash totaled $257.2 million at September 30, 2018, which compared to $298.5 million at June 30, 2018. The reduction in cash in Q3 2018 reflected a number of uses of cash that more than offset the impact of record quarterly cash flow from operating activities from continuing operations, as well as the utilization of tax losses to reduce the level of current income taxes paid. Among the main uses of cash during Q3 2018, a total of $130.3 million was used for investing activities, which included increased capital expenditures as progress with the Company’s growth projects ramped up during Q3 2018, and the use of $47.8 (C$62.5) of cash to acquire 32.6 million common shares of Osisko. An additional $37.9 million was used for financing activities, including $29.8 (C$38.9) million to repurchase 1,570,600 common shares through the Company’s normal course issuer bid, $4.8 million for quarterly dividend payments and $4.0 million used to meet finance lease obligations. There was also a $1.5 million use of cash related to foreign exchange changes.

Net cash provided by operating activities of continuing operations in Q3 2018 of $128.4 million was $56.0 million or 77% higher than net cash provided by operating activities of continuing operations of $72.4 million in Q3 2017 and increased $7.5 million or 6% from cash provided by operating activities of continuing operations of $120.9 million in Q2 2018. Free cash flow in Q3 2018 totaled $52.2 million, an increase of $15.1 million or 40% from Q3 2017. Q3 2018 free cash flow compared to Q2 2018 free cash flow of $60.7 million, with the change mainly related to higher levels of growth capital expenditures in Q3 2018, reflecting progress with the Company’s key growth projects, partially offset by increased levels of cash flow from operating activities of continuing operations in Q3 2018.

The Company’s cash position of $257.2 million at September 30, 2018 compared to total cash of $231.6 million at December 31, 2017. Contributing to the 11% increase in cash was cash provided by operating activities of $338.9 million, mainly reflecting the impact of strong revenue growth, as well as the utilization of tax losses which reduced current income taxes paid during the first nine months of 2018. These factors were partially offset by cash used for investing activities of $244.8 million, which reflected increased capital expenditures as the Company invested to advance its growth projects, as well as the investment of $47.8 million of cash to acquire 32.6 million common shares of Osisko in Q3 2018 and $16.1 (C$20.0) million of cash to acquire four million common shares of Novo in Q2 2018. The Company also used $58.3 million for financing activities, including $30.8 (C$40.3) million to repurchase 1,640,000 of the Company’s common shares, $19.5 million for the payment of finance lease obligations and $11.5 million for quarterly dividend payments. There was also a $10.2 million use of cash related to foreign exchange changes during the first nine months of 2018.

Net cash provided by operating activities of continuing operations for YTD 2018 totaled $338.9 million, a 56% increase from $217.7 million for YTD 2017, with strong revenue growth and improved unit costs being the key drivers of the increase compared to YTD 2017. Free cash flows for YTD 2018 grew 29% from YTD 2017, to $163.1 million from $126.8 million for the same period in 2017. The increase in free cash flow reflected the growth in net cash provided by operating activities of continuing operations, partially offset the impact of significantly higher capital expenditures, mainly reflecting the commencement of a number of key growth projects at Macassa and Fosterville in 2018.

YTD Performance Against 2018 Guidance

On January 17, 2018, Kirkland Lake Gold announced its guidance for full-year 2018, which, compared to 2017, included increased production levels, improved unit costs and higher levels of capital and exploration expenditures. The increase in capital and exploration expenditures was planned in support of achieving the Company’s longer-term objective of growing annual gold production over the next five to seven years to approximately a million ounces. Based on the Company’s performance during the first six months of 2018, full-year 2018 guidance was improved for a number of key measures on August 1, 2018. Included in the improvements to guidance were the following: consolidated production guidance was increased to over 635,000 ounces from over 620,000 ounces; consolidated operating cash costs per ounce sold guidance was improved to $400 - $425 from $425 - $450; production and operating cash costs per ounce sold guidance for Fosterville was improved to 275,000 - 300,000 ounces from 260,000 - 300,000 and $250 - $270 from $270 - $290, respectively; and production and operating cash costs per ounce sold guidance from Macassa was improved to 220,000 - 225,000 ounces from 215,000 - 225,000 ounces and to $460 - $480 from $475 - $500, respectively. Following completion of the first nine months of 2018, the Company was well positioned to achieve its consolidated production, cost and expenditures guidance.

Table 5. YTD 2018 Results

Key Highlights of YTD 2018 Performance Compared to Guidance

Consolidated gold production of 492,484 ounces for YTD 2018 surpassed target levels for the first nine months of the year and compared favourably to the Company’s full-year 2018 guidance of over 635,000 ounces of gold production. Production for YTD 2018 was driven by record nine-month production at both Fosterville and Macassa. For YTD 2018, production at Fosterville and Macassa totaled 231,923 ounces and 170,190 ounces, respectively, representing growth of 26% and 19%, respectively, from the comparable nine-month period in 2017. At the Holt Mine, total production for YTD 2018 was 50,996 ounces, an 8% increase from YTD 2017 and in line with target levels for the first nine months of 2018. The Taylor Mine produced 39,328 ounces in YTD 2018, a 15% improvement from the first nine months of 2017. Production at Taylor is expected to increase in the fourth quarter from average levels in the first three quarters of the year, but is unlikely to achieve the full-year 2018 guidance as at August 1, 2018 of 60,000 - 70,000 ounces.

Production costs for YTD 2018 totaled $202.8 million. Operating cash costs for YTD 2018 of $197.2 million were in line with the Company’s 2018 guidance range of $260 - $270 million and compared to $217.0 million for YTD 2017. Operating cash costs for YTD 2017 included $37.4 million of production costs for the Northern Territory, of which $31.5 million were incurred prior to the operation being place on care and maintenance effective June 30, 2017, with the remainder being incurred in Q3 2017.

Operating cash costs per ounce sold for YTD 2018 of $397 were better than the Company's guidance for full- year 2018 of $400 - $425. Operating cash costs per ounce sold at Fosterville for YTD 2018 averaged $231, better than the improved target range of $250 - $270 reflecting higher than planned grades throughout much of the year to date. Operating cash costs per ounce sold at Macassa were also better than full-year 2018 guidance, averaging $449 versus full-year guidance of $460 - $480. Operating cash costs per ounce sold at the Holt and Taylor mines averaged $681 and $767, respectively, above each mine’s guidance for full-year 2018.

AISC per ounce sold of $738 for YTD 2018 was better than the Company’s full-year 2018 guidance of $750 - $800, and a 9% improvement from $811 for YTD 2017. AISC per ounce sold at Fosterville for YTD 2018 averaged $498, while AISC per ounce sold at Macassa averaged $739.

Royalty costs totaled $18.8 million for YTD 2018, in line with full-year 2018 guidance of $22 - $27 million.

Sustaining capital expenditures for YTD 2018 totaled $127.6 million, which compared to sustaining capital expenditures of $96.1 for YTD 2017. The Company remains on track to achieve full-year 2018 guidance of $150 - $170 million.

Growth capital expenditures for YTD 2018 totaled $48.9 million, excluding capitalized exploration expenditures. Of total year-to-date growth capital expenditures as at September 30, 2018, $33.2 million or 68% of the total were incurred during Q3 2018 as work ramped up at a number of projects. Included in YTD 2018 growth capital expenditures were $29.1 million at Macassa ($21.5 million in Q3 2018), $14.3 million of expenditures at Fosterville ($7.5 million in Q3 2018), $4.0 million in the Northern Territory ($3.6 million in Q3 2018) and $1.5 million ($0.6 million in Q3 2018) split between the Holt and Taylor mines. A significant contributor to increased growth capital expenditures in Q3 3018 was significant work on the Macassa #4 shaft project, with work during the quarter including completing the shaft collar, constructing the hoist room foundations and preparing the foundations and installing the winch in advance of pouring concrete for the headframe construction early in Q4 2018. At Fosterville, expenditures related to the mine’s three key growth projects, a new ventilation system, construction of a paste-fill plant and a new water treatment plant, also increased during Q3 2018. In addition, in August, the Fosterville Mine completed and commissioned a second gravity gold circuit in the Fosterville Mill, which resulted in an immediate and significant impact on the amount of coarse gold being recovered through the mill.

Exploration expenditures totaled $69.5 million for YTD 2018. Included in YTD exploration expenditures were $52.8 million of expensed exploration expenditures and $16.7 million of capitalized exploration expenditures. Of YTD exploration expenditures, $61.5 million, or 88% of the total, have been incurred in Australia, with the remaining $8.0 million being incurred at the Macassa and Taylor mines in Canada. At Fosterville, exploration work focused on infill and extension drilling at a number of in-mine targets, as well as work to evaluate district targets in close proximity to the mine. In addition, development of an exploration drift at Harrier South at Fosterville commenced during Q2 2018, and was largely completed by the end of Q3 2018. Drilling from the new drift began in October, in order to test the depth potential of the Harrier South system, where concentrations of quartz veining with high occurrences of visible gold have previously been intersected similar to those found at the Lower Phoenix system near the high-grade Swan Zone. In the Northern Territory, drilling and development continued at the Lantern Deposit at the Cosmo mine, with drilling programs also ongoing at the Prospect and Crosscourse open pits at Union Reefs. In Canada, underground drilling at Macassa continued to generate encouraging results in support of future growth in Mineral Resources and Mineral Reserves, while drilling at Taylor continued to target additional expansion of mineralization around the Shaft and West Porphyry deposits.

Corporate G&A expense totaled $18.3 million for YTD 2018, which compared to full-year 2018 guidance of $20 - $22 million.

Revisions to Full-Year 2018 Guidance

The Company reviews full-year guidance once a quarter, as part of the preparation and approval of its consolidated financial statements and MD&A for the quarterly financial and operating results. Based on the Company’s year-to-date 2018 results as at September 30, 2018, as well as expectations for the remainder of the year, the Company has made a number of revisions to full-year 2018 guidance, both at the consolidated and operational level. Consolidated full-year 2018 production guidance has improved for the second time during 2018 and is now targeted at 655,000 - 670,000 ounces compared to the August 1, 2018 target of over 635,000 ounces and the initial target, effective January 17, 2018, of over 620,000 ounces. Likewise, full-year 2018 guidance for consolidated operating cash costs per ounce sold has also improved for the second time during the year, to $385 - $410 from $400 - $425 as at August 1, 2018. The Company’s full-year 2018 guidance for AISC per ounce sold has improved to $735 - $760 from $750 - $800. In addition, consolidated full-year 2018 guidance for growth capital expenditures has been increased to $110 - $115 million from $85 - $95 million. The increase reflects the anticipation of significant growth capital expenditures during Q4 2018 at Macassa, reflecting the accelerated delivery of the hoists, and other large components, for the #4 shaft project during the quarter, as well as capital expenditures for new projects, including investment in a new thickened tailings facility. Full-year 2018 guidance for exploration expenditures has been revised to approximately $90 million from $75 – $90 million, while corporate G&A guidance has also been revised to approximately $25 million from $20 - $22 million.

At the operational level, revisions to full-year 2018 guidance have been made for three of the Company’s operating mines. At Fosterville, full-year 2018 guidance for production has been improved for the second time in 2018, to 300,000 - 310,000 ounces from 275,000 - 300,000 ounces as at August 1, 2018. The mine’s operating cash cost per ounce sold guidance has also improved for the second time during the year, to $230 - $250 from the August 1, 2018 guidance of $250 - $270. Macassa’s operating cash costs per ounce guidance has also improved for a second time in 2018, to $450 - $470 from the August 1, 2018 target of $460 - $480. At Taylor, full-year 2018 production guidance has been revised to 50,000 - 55,000 ounces from the January 17, 2018 guidance of 60,000 -70,000 ounces, while operating cash cost per ounce sold guidance has been revised to $750 - $775 from the January 17, 2018 guidance of $625 - $650. The revisions to production and operating cash cost per ounce sold guidance at Taylor largely reflects reduced stope sizes and lower than expected grades in 2018. Other components of the Company’s full-year 2018 guidance remain unchanged from the targets released in the Kirkland Lake Gold News Release dated August 1, 2018.

Non-IFRS Measures

The Company has included certain non-IFRS measures in this document, as discussed below. The Company believes that these measures, in addition to conventional measures prepared in accordance with IFRS, provide investors an improved ability to evaluate the underlying performance of the Company. The non-IFRS measures are intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. These measures do not have any standardized meaning prescribed under IFRS, and therefore may not be comparable to other issuers. Refer to the Q2 2018 MD&A for the three months ended June 30, 2018 for the Q2 2018 non-IFRS reconciliations.

Free Cash Flow

In the gold mining industry, free cash flow is a common performance measure with no standardized meaning. Free cash flow is calculated by deducting capital cash spending (capital expenditures for the period, net of expenditures paid through finance leases) from cash flows from operations.

The Company discloses free cash flow from continuing operations as it believes the measures provide valuable assistance to investors and analysts in evaluating the Company’s ability to generate cash flow. The most directly comparable measure prepared in accordance with IFRS is cash flows generated from operations and net cash used in investing activities of continuing operations.

Operating Cash Costs and Operating Cash Costs per Ounce Sold

Operating cash costs and operating cash cost per ounce sold are non-IFRS measures. In the gold mining industry, these metrics are common performance measures but do not have any standardized meaning under IFRS. Operating cash costs include mine site operating costs such as mining, processing and administration, but exclude royalty expenses, depreciation and depletion and share based payment expenses and reclamation costs. Operating cash costs per ounce sold is based on ounces sold and is calculated by dividing operating cash costs by volume of ounces sold.

The Company discloses operating cash costs and operating cash cost per ounce sold as it believes the measures provide valuable assistance to investors and analysts in evaluating the Company’s operational performance and ability to generate cash flow. The most directly comparable measure prepared in accordance with IFRS is total production expenses. Operating cash costs and operating cash cost per ounce of gold sold should not be considered in isolation or as a substitute for measures prepared in accordance with IFRS.

Sustaining and Growth Capital

Sustaining capital and growth capital are Non-IFRS measures. Sustaining capital is defined as capital required to maintain current operations at existing levels. Growth capital is defined as capital expenditures for major growth projects or enhancement capital for significant infrastructure improvements at existing operations.

AISC and AISC per Ounce Sold

AISC and AISC per ounce sold are Non-IFRS measures. These measures are intended to assist readers in evaluating the total costs of producing gold from current operations. While there is no standardized meaning across the industry for this measure, the Company’s definition conforms to the definition of AISC as set out by the World Gold Council in its guidance note dated June 27, 2013.

The Company defines AISC as the sum of operating costs (as defined and calculated above), royalty expenses, sustaining capital, corporate expenses and reclamation cost accretion related to current operations. Corporate expenses include general and administrative expenses, net of transaction related costs, severance expenses for management changes and interest income. AISC excludes growth capital, reclamation cost accretion not related to current operations, interest expense, debt repayment and taxes.

Average Realized Price per Ounce Sold

In the gold mining industry, average realized price per ounce sold is a common performance measure that does not have any standardized meaning. The most directly comparable measure prepared in accordance with IFRS is revenue from gold sales. Average realized price per ounces sold should not be considered in isolation or as a substitute for measures prepared in accordance with IFRS. The measure is intended to assist readers in evaluating the total revenues realized in a period from current operations.

Adjusted Net Earnings and Adjusted Net Earnings per Share

Adjusted net earnings from continuing operations and adjusted net earnings per share from continuing operations are used by management and investors to measure the underlying operating performance of the Company.

Adjusted net earnings is defined as net earnings adjusted to exclude the after-tax impact of specific items that are significant, but not reflective of the underlying operations of the Company, including transaction costs and executive severance payments, purchase price adjustments reflected in inventory, the impact of discontinued operations and other non-recurring items. Adjusted net earnings per share is calculated using the weighted average number of shares outstanding for adjusted net earnings per share.

Earnings before Interest, Taxes, Depreciation, and Amortization (“EBITDA”)

EBITDA from continuing operations represents net earnings before interest, taxes, depreciation and amortization. EBITDA from continuing operations is an indicator of the Company’s ability to generate liquidity by producing operating cash flow to fund working capital needs, service debt obligations, and fund capital expenditures.

Working Capital

Working capital is a Non-IFRS measure. In the gold mining industry, working capital is a common measure of liquidity but does not have any standardized meaning.

The most directly comparable measure prepared in accordance with IFRS is current assets and current liabilities. Working capital is calculated by deducting current liabilities from current assets. Working capital should not be considered in isolation or as a substitute from measures prepared in accordance with IFRS. The measure is intended to assist readers in evaluating the Company’s liquidity.

Risks and Uncertainties

The exploration, development and mining of mineral deposits involves significant risks, which even a combination of careful evaluation, experience and knowledge may not eliminate. Kirkland Lake Gold is subject to several financial and operational risks that could have a significant impact on its cash flows and profitability. The most significant risks and uncertainties faced by the Company include: the price of gold; the uncertainty of production estimates, including the ability to extract anticipated tonnes and successfully realizing estimated grades; changes to operating and capital cost assumptions; the inherent risk associated with project development and permitting processes; the uncertainty of the mineral resources and their development into mineral reserves; the replacement of depleted reserves; foreign exchange risks; regulatory; tax as well as health, safety, and environmental risks.
