Rare and beautiful handmade products are created in the artisan workshop of the Aikhal Division by wood and bone carvers. Their artistic works can be encountered in all corners of Russia.
The major portion of diamond output of the Aikhal MPD comes from open-pit, which has been operating since 1989. According to the JORC Code, the Jubilee pipe reserves are estimated at 70 million carats.
Diamond output in 2016 – 9.231 million carats.
The open-pit operates at the same-name pipe. Based on the JORC Code, the reserves are estimated at 1.5 million carats. Diamond content in the ore of the pipe is low (0.37 carats per ton), but the average weight of the diamonds produced is 1.5-2 times greater than the average weight of the diamonds extracted from the Jubilee and Aikhal pipes. The current production plan provides for mining the deposit up to 2020.
Diamond output in 2016 – 389 thousand carats.
Aikhal underground mine
The mine has been operating since 2005 at the site of the former Aikhal open pit, which was decommissioned in 1997. In 2012, the mine reached its design capacity of 500,000 tons of ore per year.
Diamond output in 2016 – 2.6 million carats.
The ore mined by the Aikhal MPD is processed at processing plants No. 8 and No. 14. The design capacity is 1.7 million tons of ore and 10 million tons of ore per year respectively.
