Included in the determination of net income for the three months ended December 31, 2022, is an unrealized foreign exchange gain of $5.6 million, on the translation of the Company's USD-denominated long-term debts. The unrealized foreign exchange gains are a result of the relative strengthening of the Canadian dollar versus the US dollar.

Financial Highlights for Full Year 2022

• Total sales revenue at $388.9 million (US$297.3 million) compared to $298.3 million in 2021 (US$237 million sales revenue in 2021 does not include the 'upside' revenue of $10.4m from the Dunebridge agreement) at an average realized value of $146 per carat (US$112) 2021: $94 per carat, (US$75).
  
  
• Adjusted EBITDA² of $177.2 million up 31% (2021: $135.4 million).
  
  
• Earnings from mine operations of $170.5 million (2021: earnings from mine operations $113.7 million).

Included in the determination of net income is an unrealized foreign exchange loss of $28.2 million (2021: gain of $2.3 million) on the translation of the Company's USD-denominated long-term debt. The unrealized foreign exchange loss is a result of the weakening of the Canadian dollar versus US dollar.
  
  
• Capital expenditures were $60.4 million, $49.7 million of which were deferred stripping costs, with the remaining $10.7 million accounting for sustaining capital expenditures related to mine operations.

In Q4 2022, 758,000 carats were sold at an average value of $127 per carat (US$94 per carat) for total proceeds of $96.3 million (US$71.3 million) in comparison to 808,750 carats sold at an average value of $105 per carat (US$84 per carat) for total proceeds of $85.1 million (US$67.6 million) in Q4 2021.

During FY 2022, 2,657,000 carats were sold at an average value of $146 per carat (US$112 per carat) for total proceeds of $388.9 million (US$297.3 million) in comparison to 3,158,429 carats sold at an average value of $94 per carat (US$75 per carat) for total proceeds of $298.3 million (US$237 million: sales revenue in 2021 does not include the 'upside' revenue of $10.4m from the Dunebridge agreement in FY 2021).

In 2022 the Company recorded its highest annual revenues since commencement of operations. Price performance was strong, with the Company benefitting from favourable production characteristics in its recovered diamonds and the ability of the Company to capitalize on a positive market price environment, particularly for smaller size diamonds.

The first quarter of 2022 saw exceptional price growth for rough diamonds but uncertainty following Russia's invasion of Ukraine and extended delays to China's covid recovery weighed upon market sentiment during Q2 and Q3. The impact of these challenges to the Company's diamond prices were mitigated by strategically stocking weaker performing diamond categories during this time.

Stability returned to the market during Q4 and the Company saw solid price performance at its final sales of the year and into 2023. Price performance has been particularly positive for smaller sized diamonds which represent greater than 40% of the Company's production value.

The Company's rough tenders continue to attract strong competition from a large base of regular customers and a high level of competition is generated for all product segments.

The Company wishes to provide the following production outlook for 2024. While some additional carats have come into the plan, the aggregate quantity across the Life-of-Mine is not materially different from the NI 43-101 Technical Report filed in March 2022. Work has been done in order to smooth the production profile via mine sequence optimization. The Company will continue to review both 2024, and the entire Life-of-Mine plan in our normal strategic business plan process during 2023 to seek further optimization and improvement. The 2024 production outlook is as follows:

2024: 4.0 million to 4.4 million carats

"2022 was a transitional year for the company. We repaid US$110 million in debt, US$60 million from operating cash flow and utilizing the US$50 million Junior Credit Facility, leading to a significantly improved debt to EBITDA ratio, and refinanced our bonds with a 9% coupon and with no dilution to equity holders. We also discovered the Hearne Northwest Extension which has led us to review the underground potential of the Gahcho Kué mine, including how the Kennady assets may integrate into this scenario, with the objective of understanding the opportunities that may exist to substantially extend the mine life.

As we move into 2023, we continue to focus on safety, sustainability, and operational performance at the mine level. We'll continue to optimize our sales pipeline, and focus on our organic growth opportunities at the mine and at Kennady North. On the financial side of things, we are striving to improve our balance sheet by working on reducing debt directionally towards a 1:1 debt to EBITDA ratio to enable a disciplined approach to capital allocation.

We have taken the additional step of providing an outlook for 2024 where we have seen production that was in our study in the low three million carat range substantially improved, and we will continue to review as we work through the planning process."

The Hearne Northwest Extension was discovered in late 2021, when kimberlite measuring 25 meters in a bench face was exposed during routine mining operations. A delineation drilling program was subsequently launched with initial results reported last year (see news release, July 18, 2022). Drilling of the Hearne Northwest Extension as at the end of 2022 totaled 16 drillholes and 5,026 meters. Ten of the sixteen drillholes had significant kimberlite intersections that have been used to model the Hearne Northwest Extension (see news release, November 30, 2022). Phase two drilling started in early 2023 with 13 drillholes planned (5,580 meters total) of which three have been completed. Two drillholes intersected HK and HK transitional kimberlite. Logging, petrographic, mineral chemistry and microdiamond analysis is underway to properly define the HK and TK contacts in the extension and their relationship to the main Hearne kimberlite. Details for the 2023 drilling results are provided in the table below.

The results of this ongoing drill program will inform the next stage of study on potential underground mining at Gahcho Kué. Results, interpretation and decisions regarding next steps are expected to be complete by the end of Q3 of 2023.

The following table summarizes the key operating statistics for Q4 2022 and FY 2022, and the previous year, at the Gahcho Kué Mine.

Mountain Province Diamonds is a 49% participant with De Beers Canada in the Gahcho Kué diamond mine located in Canada's Northwest Territories. The Gahcho Kué Joint Venture consists of several kimberlites that are actively being mined, developed, and explored for future development. The Company also controls over 113,000 hectares of highly prospective mineral claims and leases surrounding the Gahcho Kué Mine that include an Indicated mineral resource for the Kelvin kimberlite and Inferred mineral resources for the Faraday kimberlites. Kelvin is estimated to contain 13.62 million carats (Mct) in 8.50 million tonnes (Mt) at a grade of 1.60 carats/tonne and value of US$63/carat. Faraday 2 is estimated to contain 5.45Mct in 2.07Mt at a grade of 2.63 carats/tonne and value of US$140/ct. Faraday 1-3 is estimated to contain 1.90Mct in 1.87Mt at a grade of 1.04 carats/tonne and value of US$75/carat. All resource estimations are based on a 1mm diamond size bottom cut-off.
