PJSC Severalmaz, in which ALROSA owns 99.6% of shares, is engaged in the development of Lomonosovskoye deposit in the Arkhangelsk Region. It is one of the Company’s key development projects.

Severalmaz develops Lomonosov primary deposit that consists of 6 kimberlite pipes with the total diamond resources over 115 million carats. Two pipes, Arkhangelskaya and Karpinskogo-1, are being developed now.

Commercial production of diamonds near the White Sea coast started in 2005, when the first module of the processing plant with annual capacity of 1 million tons of ore was put into operation at the Lomonosov Mining and Processing Division (MPD).
