Mountain Province Diamonds Announces Third Quarter 2025 Production and Sales Results, Update on Guidance, Details of Third Quarter 2025 Earnings Release, and Conference Call
In the Company's quarterly Management Discussion and Analysis (MD&A) we provide guidance targets in respect of production and cost metrics for the 2025 fiscal year, which include, carats recovered and production costs per carat recovered and per tonne treated. We wish to issue revised guidance in respect of these three metrics only.
The reduction in carats recovered, is due to lower than planned grade from the ore stockpile material treated, resulting in a revised guidance range of 4.0 million to 4.2 million carats recovered, compared to previous guidance of 4.3 million to 4.7 million carats recovered.
In respect of production costs, although operating costs remain largely in line with budget, the combination of lower carats recovered and the release of previously capitalised costs into production costs as ore stockpile tonnes reduce, pushed the production costs per carat beyond the top end of guidance, with a revised guidance range of $125 – $130 per carat recovered, compared to original guidance of $92 – $107 per carat recovered. The reduction in the tonnes of ore stockpile, similarly, explains the revised guidance range of $145 – $155 per tonne treated, compared to original guidance of $120 – $137 per tonne treated.
In the Quarter, 409,081 carats were sold for $29.2 million ( US$21.2 million ), averaging $71 per carat ( US$52 per carat). By comparison, in Q3 2024, 679,599 carats were sold for $69.4 million ( US$50.8 million ), averaging $102 per carat (US$75per carat).
The Company will host its quarterly conference call on Wednesday November 12 , 2025, at 11:00am ET . Prior to the conference call, the Company will release Q3 2025 financial results on November 11 , 2025 after-market.
