Alrosa Moves to Resume Operations at Mir Mine Nearly 10 Years After Flooding

Alrosa is considering restarting operations at its Mir mine in Yakutia, almost ten years after it was shut down following the deadly Mir mine flood 2017.

Once a major production asset for the company, the Mir mine was forced to cease operations after the 2017 flooding tragedy, which caused multiple fatalities and led to an indefinite suspension of mining activities. Since then, the site has remained inactive while the company carried out extensive safety evaluations and technical studies.

Recent disclosures indicate that Alrosa is now exploring a phased redevelopment of the deposit using underground mining techniques. The proposed revival would involve substantial investment and is expected to unfold over several years, pending feasibility assessments, regulatory approvals, and safety clearances.

The potential restart forms part of Alrosa’s long-term strategy to maintain production capacity in a changing global market. Despite ongoing short-term pressure in the diamond sector—especially in rough diamond demand—the company appears to be preparing for improved market conditions in the future.

For the global diamond industry, including India’s manufacturing sector, reviving a historically important mine like Mir could influence long-term rough diamond supply. However, any noticeable impact is likely to emerge only over the medium to long term due to the complexity and scale of redevelopment.

This initiative also highlights a broader industry pattern, with major mining companies investing in future output pipelines despite current market challenges. Further developments are expected as Alrosa advances its technical and investment plans for the Mir project.
