Mountain Province Diamonds Announces First Quarter 2019 Results and Revises 2019 Guidance

TORONTO and NEW YORK, May 8, 2019  – Mountain Province Diamonds Inc. (“Mountain Province”, or the “Company”) (TSX and NASDAQ: MPVD) today announces its financial and operating results for the quarter ended March 31, 2019 (or “Q1”). All figures are expressed in Canadian dollars unless otherwise noted.

The Company is also pleased to announce that as a result of plant enhancement modifications, it has increased its 2019 guidance from 3.1 – 3.2 million tonnes treated to 3.2 – 3.3 million tonnes.

Operational Highlights for First Quarter 2019

• 870,949 tonnes treated, an 11% increase on comparable quarter (Q1 2018: 786,000 tonnes).
• 1,584,552 carats recovered at an average grade of 1.82 carats per tonne, slightly lower than the same period last year and mainly as a result of planned mine sequencing of lower grade ore tonnes mined and treated during the quarter and due to the previously announced plant modifications (Q1 2018: 1,641,000 carats and 2.09 carats per tonne).
• 9,528,018 total tonnes mined, a 16% increase on comparable period (Q1 2018: 8,202,000).

Financial Highlights for First Quarter 2019

• Revenue from 643,739 carats sold at $60.7 million (US$45.8 million) compared to $66.6 million from 527,000 carats sold in Q1 2018 (US$52.4 million) at an average realised value of $94 per carat (US$71) 2018: $126 per carat, (US$99).
• Adjusted EBITDA¹ of $19.7 million compared to $33.6 million in Q1 2018, mainly due to the rough diamond market being weaker in Q1 2019 compared to Q1 2018 and the sale of a different mix of goods with fewer better-quality and special stones sold in Q1 2019 compared to Q1 2018. Adverse weather conditions during the quarter also affected the costs.
• Earnings from mine operations $10.2 million compared to $24.6 million in Q1 2018.
• Cash costs of production, including capitalized stripping costs¹ of $111 per tonne treated (2018: $76 per tonne) and $61 per carat recovered (2018: $37 per carat).
  • The cash costs per tonne treated during the quarter are at the lower end of the Company’s guidance for 2019, but higher than the same period last year.  The cost per tonne treated for Q1 2019 is 10% higher than the 2018 average cost of $101 per tonne as expected, and mainly due to the adverse weather cost impact and the additional planned increase in waste tonnes mined.
  • The cash cost of production per carat is higher in Q1 2019 than in Q1 2018 as a result of lower grade material planned for the quarter and subsequently lower carats recovered, in addition to the higher costs associated with larger volumes of waste mined.
• Net income at March 31, 2019 was $2.5 million or $0.01 earnings per share (2018: net income $0.07 million or $0.00 earnings per share). Included in the determination of net income at March 31, 2019 are unrealized foreign exchange gains of $8.6 million, on the translation of the Company’s USD-denominated long-term debt. The unrealized foreign exchange gains are a result of the strengthening of the Canadian dollar versus US dollar.
• Capital expenditure in the first quarter of 2019 was $10.4 million, $7.3 million of which was waste stripping and the remaining $3.1 million was sustaining capital related to mine operations.
• Cash position of $11.3 million (December 31, 2018: $30.7 million) and net working capital of $91.6 million (December 31, 2018: $87.2 million). The winter road season was successful with all required spares and consumables delivered to site, the reduction in cash from December 2018 is mostly due to the winter road season and will improve later in the financial year. The US$50 million revolving credit facility remains undrawn.

Market Highlights for First Quarter 2019

The rough diamond market is showing signs of stabilising during the quarter, with lower rough supplies predicted for 2019 and cutting centre inventories expected to return to more normal levels.

Reid Mackie, the Company’s Vice President of Diamond Marketing, commented: “We have seen stability return, both in terms of diamond demand and prices achieved which resulted in our first quarter sales outperforming our expectations. Most of our diamond categories experienced modest but consecutive price increases and healthy demand from customers resulted in all lots offered being sold.

2019 Revised Guidance

The Company is pleased to revise its 2019 outlook for production as a result of ongoing plant enhancements, this has enabled higher throughput for tonnes treated. The previous 2019 operational outlook consisted of approximately 3.1 million to 3.2 million tonnes treated. The total ore tonnes treated has been revised to 3.2 million to 3.3 million tonnes due to the increased plant performance. The Company maintains its total carat production range of 6.6 million and 6.9 million carats, as previously announced (100% basis) with recovered grades of between 2.12 and 2.16 carats per tonne. The Company also maintains its cost guidance of $110 – $120 per tonne or $50 – $54 per carat recovered for fiscal year 2019.

Q1 2019 Summary

Q1 2019 mining results were in line with the Company’s expectations with over 9.5 million tonnes of material mined, 16% higher than the same period last year.

The average grade for the first quarter has been lower than the average for 2018, but in line with the expected outcome for Q1. The lower grade during the quarter was partly driven by adverse weather conditions preventing access to planned higher grade ore areas as well as mine plan sequencing where lower grade ore was mined from the South West Corridor and parts of the Hearne pit. In addition to this, the plant enhancements and the change to the bottom screen sizes has resulted in higher throughput in the plant.  The changes have resulted in the recovery of coarser size frequency distribution and is expected to translate into an increased average value per carat recovered. The plant enhancements will continue to be implemented and monitored as the year progresses.

The plant treated 870,949 tonnes, or approximately 9,677 tonnes per day, 11% higher than the same period last year, and recovered just under 1.6 million carats. The Gahcho Kué Mine remains on track to achieve it’s 2019 production guidance of 6.6 – 6.9 million carats.

The total ore tonnes mined were slightly less than planned for in Q1, due to extended excessive cold weather periods which prevented access to certain parts of the orebody. The ore stockpile has been utilized to accommodate higher throughput in the plant. The shortfall of ore tonnes mined year to date will be caught up during the summer months.

Stuart Brown, the Company’s President and Chief Executive Officer, commented: “We are pleased with the Q1 operational and financial results for the Gahcho Kué Mine, given the mining area which consisted of lower grade ore. Production figures are slightly ahead of expectations and costs are at the lower end of our guidance for 2019. The 2019 target of 3.3 – 3.45 million carats (our 49% share of the full production) recovered, remains unchanged. We are encouraged by the early results of the plant changes implemented and look forward to updating the market on the progress of this initiative in the coming months.”
