The Nyurba Mining and Processing Division (MPD) is one of the youngest enterprises of ALROSA. It operates at the Nakyn ore field. In particular, it develops the following deposits: Nyurbinsky and Botuobinsky open-pits, and two same-name alluvial placers. Share in ALROSA Group’s production totaled 18% in 2016.
The division employs more than 1,500 people. At the Nyurba Division, for the first time throughout history of ALROSA, the rotation work scheme has been applied with the involvement of workers living in Mirny, Nyurba, and Verkhnevilyuisk.
At the prospects of Nyurbinskaya and Botuobinskaya pipes all the works are performed by Nyurba Mining and Processing Division based on service contracts with OJSC ALROSA-Nyurba, the subsidiary company that holds the exploration and mining license.

In 2015, Botuobinskaya pipe started ore mining; it contains many gem and near-gem quality diamonds with a high transparency and low proportion of colored stones. Diamond production at the pipe will exceed 2 million carats when it reaches its design capacity of 400 thousand tons of ore per year. Diamond output in 2016 – 684 thousand carats.
The Nyurbinskoye placer deposit is localized in the immediate vicinity of the Nyurbinskaya pipe, which is a source of diamonds; the Botuobinskaya placer deposit is closely associated with the same-name kimberlite pipe.
