Diamond miner Alrosa’s first-quarter production slumps

Diamond miner Alrosa on Friday reported a 17% year-on-year decrease in its first-quarter production, as the shutdown of the Mir underground division weighed on its performance and lower-grade ores were processed from the Jubilee pipe. The miner produced 7.42-million carats in the quarter, compared with 8.93-million carats in the corresponding period of 2017, and 10.07-million carats in the preceding quarter.
