Leadership Transition

Mark Wall has decided to step down from his position to explore other opportunities, though he will remain available until December 19, 2025, to aid a smooth transition for his successor.

The Board has already initiated the search for a new CEO and will update stakeholders on progress in due course.

Operational Highlights

Despite the leadership change, operational developments at the Gahcho Kué mine are promising. Recently, the company reported that it has begun mining through the transitional phase of the high-grade 5034-NEX orebody, an essential step that signals potential production efficiency and profitability. The successful completion of a scheduled five-day maintenance shutdown during the third quarter has also positioned the Gahcho Kué mine for strong performance in the approaching quarters of 2025 and beyond.

The mine comprises several kimberlites that are actively mined and developed, underscoring the importance of stable leadership alongside operational excellence.

Future Outlook

The company has highlighted its ongoing commitment to exploring and developing additional mineral properties surrounding the Gahcho Kué mine, controlling over 96,000 hectares of prospective claims and leases.

Estimates show that Kelvin may hold approximately 13.62 million carats in 8.5 million tonnes at a grade facilitating economic viability, further emphasizing the importance of a robust operational strategy moving forward.

The ongoing advancements at the Gahcho Kué mine alongside this leadership transition signify pivotal strategic pagination for Mountain Province Diamonds. As the board and stakeholders navigate these changes, all eyes will be on the company’s ability to adapt and thrive in a demanding market.
