Russian diamond miner Alrosa is evaluating plans to restart operations at its Mir mine in Yakutia, nearly a decade after the asset was shut following the fatal Mir mine flood.

The Mir mine, historically one of the company’s key producing assets, ceased operations after a catastrophic flood in 2017 that resulted in multiple fatalities and halted mining activity indefinitely. Since then, the deposit has remained inactive, with the company focusing on safety reviews and technical assessments for any potential restart.

According to company disclosures and industry reports, Alrosa is now considering a phased redevelopment of the Mir deposit through underground mining methods. The proposed restart is expected to require significant capital investment and will likely be executed over a multi-year timeline, subject to feasibility studies, regulatory approvals, and safety clearances.

The potential revival of Mir is part of Alrosa’s broader strategy to sustain long-term production capacity amid evolving global market conditions. While the diamond market continues to face near-term demand pressures, particularly in the rough segment, the company appears to be positioning itself for future supply stability once market conditions improve.

For the global diamond trade, including India’s manufacturing sector, the restart of a historically significant mine such as Mir could have implications for long-term rough availability. However, any impact on supply volumes is expected to materialize only over the medium to long term, given the scale and complexity of redevelopment.

The move also reflects a wider trend among major mining companies to secure future production pipelines despite current market headwinds. Further updates are expected as Alrosa progresses with technical evaluations and investment planning related to the Mir project.
