Mountain Province Diamonds Announces First Quarter Financial Results and Guidance for 2021

Additionally, the Company is providing production and cost guidance for 2021.

Financial Highlights for First Quarter 2021 (production and unit cost figures for Q1 2021 were affected by the 22 day operational stand-down in February)

• 603,000 carats sold, with total proceeds of $54.2 million (US$42.7 million) at an average realised value of $90 per carat (US$71).
• Adjusted EBITDA¹ of $19.1 million.
• Earnings from mine operations of $13.7 million.
• Cash costs of $139 per tonne treated and $62 per carat recovered, including capitalized stripping costs¹.
• Net income of $7.3 million or $0.03 earnings per share. Included in the determination of net income for the three months ended March 31, 2021 are unrealized foreign exchange gains of $5.0 million, on the translation of the Company's US$-denominated long-term debt and Dunebridge revolving credit facility. The unrealized foreign exchange gains are a result of the strengthening of the Canadian dollar versus the US dollar.

Operational Highlights for First Quarter 2021

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

• Unplanned 22-day operational stand-down in February due to measures taken to limit the spread of Covid-19 at Gahcho Kué
• 625,582 ore tonnes treated, a 31% decrease relative to Q1 2020, and a 15% decrease relative to Q4 2020 (Q1 2020: 9,356,785 tonnes treated; Q4 2020, 736,138 tonnes treated)
• • Average processing rate of 9,200 tonnes per day (excluding operational stand-down time), a 7% decrease relative to Q1 2020 (9,917 tonnes per day)
  • Processing plant achieved several days over 11,500 tonnes of feed in closing days of Q1 2021, demonstrating operational flexibility
• 1,392,128 carats recovered, 16% lower than the comparable quarter (Q1 2020: 1,655,121 carats), impacted by the unplanned 3-week operational stand-down in February
• Average grade of 2.23 carats per tonne, a 22% increase relative to Q1 2020 (1.83 carats per tonne)

2021 Guidance: (all figures quoted on a 100% basis)

• 35 - 37 million total tonnes mined (ore and waste)
• 3.3 - 3.5 million ore tonnes mined
• 3.15 - 3.3 million ore tonnes treated
• 6.3 - 6.5 million carats recovered
• Production costs of $125 - $135 per tonne treated
• Production costs of $58 - $63 per carat recovered
• Sustaining Capital Expenditure of $21 million

Production and cost guidance reflects the unplanned 3-week operational stand-down during the first quarter. Process plant throughput is expected to benefit from a planned production mitigation strategy to change to 1.1mm cut-off screens (up from 0.8mm). This change combined with planned grade management is expected to result in the recovery of 6.3 - 6.5 million carats, from 3.15 - 3.3 million tonnes treated.

Sales Highlights for First Quarter 2021

As previously released, during the first quarter 602,773 carats were sold for total proceeds of $54.2 million (US$42.7 million) resulting in an average value of $90 per carat (US$71 per carat). This is a 6% increase relative to the average value per carat in Q4 2020 of $85 per carat (US$64 per carat), and a near-return to pre-pandemic pricing levels seen in Q1 2020 (US$75 per carat). The increase in average values and the positive product mix sold in Q1 reflected the growing confidence across the rough diamond markets. Overall, on a like for like basis, compared to Q1 2020 our current average diamond value is now ahead of Q1 2020.

Stuart Brown, the Company's President and Chief Executive Officer, commented:

"With a tough quarter behind us, our focus now shifts to making up the carat shortfall, and revenue over the remainder of 2021. Despite the unplanned 22-day operational stand-down in February, we expect the process plant to make up most of the lost production by increasing the plant throughput levels with the bottom screen change. This will have a positive effect on the average value of diamonds recovered. We expect this to drive the recovery of between 6.3 - 6.5 million carats, at or just below 2020's recovery of 6.5 million carats.

The impact of the COVID-19 outbreak at the mine, and the subsequent shut down has meant that we have had to cancel our planned May diamond sale in Antwerp. The cancellation of the sale coincided with our usual high cash spend during the annual winter road supply exercise, this meant that we faced some short-term liquidity challenges. We are now able to confirm, as per the earlier announcement today, that we have agreed terms with Dunebridge Worldwide Ltd. for a short-term loan of US$33 million that will address our near term liquidity needs and allows us the time to execute on this year's revised mine plan. This plan shows us largely making up the lost production, revenue and cash generation during 2021 and should allow us to repay this loan by the end of 2021.

The diamond industry is bearing up well through the ongoing challenges of COVID-19, globally retailers continue to report increasing revenue as economic activity increases, in turn this is having a positive impact on polished and rough diamond prices. There will, no doubt, still be issues to deal with in the coming months such as the intense second wave in India, hopefully with all the work being done and support we will see a recovery in India and all participants in the industry will benefit from the continued desire for natural diamonds. We believe that the recovery across all sectors of the industry will continue for the remainder of 2021."
