Market Highlights

As previously disclosed, during the third quarter of 2021, 1,028,327 carats were sold for total proceeds of $93.9 million (US$74.1 million) resulting in an average value of $91 per carat (US$72 per carat). This compares to 718,549 carats sold at an average value of $90 per carat (US$73 per carat) for total proceeds of $64.7 million (US$52.6 million) in Q2 2021. This brings year-to-date sales to 2,349,644 carats, for total proceeds of $212.5 million (US$169.4 million) resulting in a year-to-date average value of $90 per carat (US$72 per carat).

The positive market environment which began early in the year persisted through the third quarter, resulting in strong price growth across all size classes. Indexed on a like-for-like basis, the Company is now achieving sales prices 47% above its pre-Covid benchmark of February 2020. As global economies continue to recover and the Covid-19 pandemic becomes less restrictive, consumer confidence heading into the important holiday retail buying season is expected to strengthen, further supporting price growth in the Diamond industry. Additionally, supply-demand dynamics are expected to favour the company as volumes sold by industry majors remain at multi-year lows.

Jonathan Comerford, the Company's Chairman and Interim Chief Executive Officer, commented:

"We're extremely pleased to report the strong third quarter operating and financial results. With the mine returning to peak efficiency levels and the diamond market exceeding pre-Covid levels, the company is on a strong footing as we enter 2022. With our new incoming CEO Mark Wall at the helm, we're looking forward to taking full advantage of the strong rebound in the diamond market, with our Gahcho Kué Diamonds in a great position to fill the gap that the Argyle Mine closure has left.

As we head into the end of the year with a good amount of cash in the bank, and an improved financial outlook backstopped by the strong performance we're seeing at the mine, we have many more options available to us than before as we explore ways to streamline the balance sheet, as we work with our supportive and constructive bondholders.

We believe that Mountain Province Diamonds is exiting a challenging time for the diamond industry as a whole. With the Covid-19 overhang on the industry slowly fading, supply and demand dynamics are expected to continue to tilt in our favour, to the benefit of all of our stakeholders."

Forward-looking statements are based on the opinions and estimates of management at the date the statements are made, and are based on a number of assumptions and subject to a variety of risks and uncertainties and other factors that could cause actual events or results to differ materially from those projected in the forward-looking statements. Many of these assumptions are based on factors and events that are not within the control of Mountain Province and there is no assurance they will prove to be correct.

Factors that could cause actual results to vary materially from results anticipated by such forward-looking statements include the development of operation hazards which could arise in relation to COVID-19, including, but not limited to protocols which may be adopted to reduce the spread of COVID-19 and any impact of such protocols on Mountain Province's business and operations, variations in ore grade or recovery rates, changes in market conditions, changes in project parameters, mine sequencing; production rates; cash flow; risks relating to the availability and timeliness of permitting and governmental approvals; supply of, and demand for, diamonds; fluctuating commodity prices and currency exchange rates, the possibility of project cost overruns or unanticipated costs and expenses, labour disputes and other risks of the mining industry, failure of plant, equipment or processes to operate as anticipated.

These factors are discussed in greater detail in Mountain Province's most recent Annual Information Form and in the most recent MD&A filed on SEDAR, which also provide additional general assumptions in connection with these statements.
