Yakutia 24 TV channel: ALROSA is carrying out drilling work on Miir former extraction site to restore diamond production.
Yakutniproalmaz Institute of ALROSA is working on a mine restoration project. For this, the company held an international competition and found the best option on its results.
“We’ve been advised to build two new shafts on an old or new site. Plus, we start working out and go to the maximum possible depth that is one kilometer and we start conducting mining operations rising from bottom to top. At the same time, we need to carry out a quarry reconstruction and install a drainage system at the bottom. Drainage system will guarantee no breakthrough in large volumes of water there,” says Igor Zyryanov, research deputy director at the Yakutniproalmaz Institute.
The miners will be building a new mine. According to preliminary estimates, the Mir mine holds 140 million carats of diamonds.
“To date, 140 million carats is one of the five largest deposits in the world. If we take that each carat costs an average of $200, then this is $28 billion. We should get revenue by the end of the 2020s, when we get the first ore. I think this will be one of the three largest diamond mining sites,” comments Kostantin Garanin, chief geologist at the company.
At the end of 2019, ALROSA held a tender to determine a drilling contractor at the mine. The competition was won by the oil company VPT-NEFTEMASH. Exploration by drilling will be carried out within aquifers and powerful saline formations. It is noted that drilling is around the clock ahead of schedule.
After drilling, studies of the obtained kimberlite samples will begin. Geologists will be able to say reserves of the field holds in early 2022. According to optimistic forecasts of specialists, the construction of a new mine can start in 2024, and diamond mining – in the late 2020s.
