ALROSA, the world leader in diamond mining, announces the recovery of a large 60.32-carat rough diamond. According to experts, rough diamond costs about USD 174.5 thousand. Octahedron crystal, transparent with yellow hue, was recovered by dredge No. 203 within Mirny Mining and Processing Division, from Gornoye alluvial deposit.

Gornoye alluvial deposit was discovered in 1956. It is located on the left bank of Malaya Botuobiya river, 26 km south-east of Mirny. Apart from Gornoye placer deposit, Mirny Mining and Processing Division develops Mir and Internatsionalny underground mines, Vodorazdelnye Galechniki and Irelyakh placer deposits, and Tailings from Processing Plant No. 5 (technogenic deposit).

In 2016, Mirny Mining and Processing Division produced almost 7.8 million carats of rough diamonds ─ 21% of all rough diamonds mined by ALROSA Group.
