November 7, 2018 – PJSC ALROSA, the world leader in diamond mining, announces the recovery of the first large gem-quality rough diamond from Verkhne-Munskoe deposit that was commissioned on October 31.

The transparent round-shaped octahedron crystal with insignificant yellow hue was recovered from Zapolyarnaya pipe – one of four kimberlite pipes of the deposit. The 51.49-carat rough diamond measures 23 by 22 by 15 mm. The approximate age of the extracted crystal is over 350 million years.

“It is the first rough diamond over 50 carats from Verkhnyaya Muna. We have just started mining here, so it is a very promising event evidencing of the good potential of the deposit, says Alexander Makhrachev, Director of Udachny Mining and Processing Division. – Despite small inclusions and cracks, this stone is undoubtedly a gem-quality rough diamond that will bring to life one or several high-grade polished diamonds.”

Verkhne-Munskoe diamond deposit is located in Western Yakutia 170 km from Udachny. Four kimberlite pipes have been explored so far: Zapolyarnaya, Deimos, Novinka, Komsomolskaya-Magnitnaya. The deposit is calculated to yield some 1.8 million carats of rough diamonds per year, and its reserves are enough for mining for more than 20 years. The development of Verkhne-Munskoe deposit is ALROSA’s largest investment project. At the pre-mining stage, investments amounted to some RUB 16 billion, and total investments, including maintenance of mining up to 2042, are estimated at some RUB 60 billion. The deposit was officially commissioned on October 31, 2018. Diamond mining was started by the Russian President Vladimir Putin.
