Alrosa Starts Mining at New Kimberlite Pipe

July 10, 25 by John Jeffay

(IDEX Online) - Alrosa has started operations at additional kimberlite pipe at its Lomonosov deposit, one of the largest diamond mines in Russia.

The state-run miner said on Tuesday (8 July) that the Karpinsky-2 pipe, one of six at Lomonosov, held more than 40m tonnes of diamond bearing ore.

Its subsidiary, Severalmaz, already mines two other pipes at the site in Arkhangelsk, northwestern Russia - Arkhangelskaya and Karpinsky-1 - and is now mining Karpinsky-2.

Alrosa, currently sanctioned by the G7 nations, said in March that it was suspending production at four low-margin mines - Zapolyarny, Magnitny, Khara-Mas and Ochuos - because of a "deep crisis" in the industry.

It is also selling a large proportion of its output to Gokhran, the state repository of precious metals and gemstones.

Gokhran has historically functioned as a buffer, stockpiling diamonds during market downturns and selling them back when demand recovers, for example, during the 2009 financial crisis.
