Upgrades hit Alrosa ore output

Russian diamond producer Alrosa has pointed to the downtime impacts of various upgrades for a decline in ore and gravels output in the second quarter.

Upgrades hit Alrosa ore output

Alrosa said an increase in stripping operations at its Jubilee pipe and an optimisation underway of the mining fleet at Severalmaz were behind a fall in ore and gravels output of 8% to 8.0 mt compared to the previous quarter.

Diamonds output in the quarter was also down 8%, but this was mainly due to a seasonal increase in the processing of low-grade gravels.

Ore and gravels processing grew by 26% to 7.3 mt driven by a seasonal growth in the processing of gravels from alluvial deposits and an increase in ore processing at Severalmaz.

Q2 diamond grade was seasonally down 27% qoq (+24% yoy) to 0.96 cpt on the back of increased production at alluvials

Alrosa restated its Lomonosov mining and processing division, Severalmaz, on  March 1, a month earlier than previously planned. Due to the COVID-19 pandemic, Severalmaz had switched to seasonal operations.
