Mountain Province Diamonds Announces Second Quarter 2019 Production and Sale Results and Provides Q2 Conference Call Details

Press Release

TORONTO and NEW YORK, July 17, 2019  – Mountain Province Diamonds Inc. (“Mountain Province”, the “Company”) (TSX and NASDAQ: MPVD) today announces production and sales results for the second quarter ended June 30, 2019 (“Q2 2019”) from the Gahcho Kué Diamond Mine (“GK Mine”).  The Company also releases the details for its Q2 2019 earnings conference call and webcast.  All figures are expressed in Canadian dollars unless otherwise noted.

Q2 2019 Highlights
(all figures reported on a 100% basis unless otherwise stated)

• 10,865,263 total tonnes mined, a 6% increase on comparable period (Q2 2018: 10,285,000).
• 882,374 tonnes of ore treated a 2% decrease from comparable quarter (Q2 2018: 899,000 tonnes).
• 1,730,147 carats recovered at an average grade of 1.96 carats per, 10% lower than comparable quarter (Q2 2018: 1,930,500 carats and 2.15 carats per tonne). The grade variance year over year is mainly a function of mining lower grade ore tonnes in Q2 2019 from Hearne and SWC Kimberlites in comparison to higher grades from the 5034 Kimberlite in Q2 2018. In addition, the ongoing plant enhancement modifications and size frequency optimization result in the removal of the very small, lowest value diamonds from the recovery process further contributing, as expected, to fewer carats recovered.
• 1,077,730 carats sold at an average value of $89 per carat (US$67 per carat) for total proceeds of $95.8 million (US$71.7 million) in comparison to 1,113,724 carats sold at an average value of $89 per carat (US$69 per carat) for total proceeds of $99.1 million (US$76.8 million) in Q2 2018. It is important to note that the majority of the carats sold in Q2, 2019 were from the Hearne and SWC kimberlites as per plan, which contain lower average values per carat than the 5034 ore body, that made up most of the production in the previous year. The achievement of similar average values per carat sold year over year is very encouraging and can be attributed to the ongoing engagement with its JV Partner, De Beers Canada to focus on optimizing the process facilities recoverable size frequency distribution.

Q2 2019 Production Statistics¹

Q2 2019 Diamond Sales

At the Company’s Q2 2019 sales, values for the larger, (greater than 5 carats), better quality diamonds that contribute the majority of the Company’s revenue, remained stable.  However, values for smaller diamonds and lower quality categories have again come under pressure.

Q2 2019 Summary

Q2 2019 production results were in line with the Company’s expectations, with over 10.8 million tonnes of material mined, 6% higher than the same period last year. The total carats recovered and grade in Q2 2019 were 10% lower than the same period last year, but ahead of plan. The lower grade and carats recovered during Q2 2019, as stated in previous announcements, are driven by the grade and carats associated with the source of ore feed for each period.  In Q2 2019 the majority of the plant throughput consisted of the Hearne and SWC Kimberlites which contain lower average values per carat than the 5034 Kimberlite, where majority of the production was sourced from in Q2 2018.  In addition, the plant process modifications have, as planned, resulted in the ability of the plant to treat more ore resulting in the removal of the very small, lower value diamonds but increasing the number of larger more valuable diamonds recovered with the increased tonnage.  This outcome is expected and lower grades and carats recovered are offset by generating higher average values from the increased production.

The Company’s sales results in Q2 2019, and year over year value per carat performance demonstrate that the plant process changes are having a positive impact on the average value of the diamonds recovered. Considering that lower quality ore was being mined during Q2 2019 in comparison to Q2 2018, and in addition to a softer diamond market year over year, achieving similar average values per carat in Q2 2019 is very encouraging.  The Company and its JV Partner, De Beers Canada, continue to implement these changes and expect full completion by early Q2 2020.  Therefore, the Company is well positioned for 2020 and beyond, as it plans to mine larger percentages of the 5034 Kimberlite.

The plant treated 882,374 tonnes and produced over 1.73 million carats in Q2 2019, in comparison to 899,000 tonnes treated and 1.93 million carats recovered in Q2 2018; 2% and 10% lower than the same period last year respectively, but slightly ahead of plan for the first half.  The GK plant continues to perform well and the process improvements are showing great results, demonstrated by similar average realized values per carat, and taking into account the source of diamonds for the two periods and corresponding values per carat.  Total tonnes treated during Q2 2019 was slightly less than what was achieved compared to the same period last year due to variable mixture of the plant feed for each period and the rate of processing for each ore type which can impact monthly throughput figures year over year.  Taking this into account, and considering the sources of ore from a year ago, the plant has achieved 4% higher throughput in the first half of 2019 compared to the first half of 2018.

Stuart Brown, the Company’s President and Chief Executive Officer, commented: “We have completed the first half of the 2019 financial year ahead of expectations and seen continued improvement in production through the first half of 2019.  The plant processing enhancements and modifications are progressing well and the results thus far are encouraging.  The Company’s diamond sales were also slightly ahead of expectations due to a better product mix.  As widely reported by various diamond producers and industry commentators, the rough diamond market is challenging at present, and we expect to see continued volatility in the market for rough diamonds in the near term.  Despite the current market conditions, we are pleased to see our diamonds selling consistently at competitive prices.  With lower volumes being sold into the rough market of late, and the relatively positive retail sales reported, we expect to see price stability over the coming months.  We remain on track to achieve our 2019 forecast of 3.3 – 3.45 million carats (our 49% share of the full production) recovered, and look forward to updating the market further as we deliver on our milestones for the rest of 2019 and beyond.”

The Company will release Q2 2019 financial results on Tuesday August 6^th, 2019 after market hours. The Company will host its quarterly conference call on Wednesday August 7^th, 2019 at 11:00am EDT.
