Verkhne, rich in large crystals

Alrosa
announces the preliminary results of an experiment aimed at clarifying the
diamond-bearing capacity of the north western area of the Zapolyarnaya pipe,
which is a part of the Verkhne-Munskoye deposit. According to the data
obtained, Verkhne-Munskoye can become one of the richest in large diamonds
among Alrosa’s deposits.
The
experiment took place on March 11-15. Through that period, the processing plant
N12 in the town of Udachny was supplied with ore exclusively from the north-western
part of the Zapolyarnaya pipe. The main goal was to find out the color
characteristics of diamonds, the grades and the cost of one carat in this
particular part of the pipe.
During
the experiment, about 100 thousand tons of ore was processed. The diamond
grades appeared to be higher than planned.
“The
experiment showed once again that the Verkhne-Munskoye deposit is rich in large
crystals. In 5 days, we extracted 239 large (over 8 carats) diamonds from the
Zapolyarnaya pipe, or more than 3.5% of the number of diamonds extracted during
the experiment. This is a very significant indicator,” Andrey Cherepnov, Alrosa
Chief Engineer, said.
There
were two gem-quality stones weighing 51.15 and 70.67 carats among the extracted
large diamonds. In addition, four large diamonds of lower quality were mined;
the largest one weighs 268 carats. All the crystals were sent to the ALROSA’s
Diamond Sorting Center in the town of Mirny, where the main quality
characteristics of these stones will be determined and their assessment made.
Earlier,
two large high-quality diamonds, weighing 51.49 and 98.8 carats, have already
been mined at the Verkhne-Munskoye deposit.
