The Savkinsky deposit located in the Jewish Autonomous Oblast is viewed as the largest known brucite deposit anywhere in the world by volume of reserves, with approximately 30 million tons of ore, according to latest estimates.The deposit was discovered at the beginning of the 1970s during a planned geological exploration by Soviet Union’s Ministry of Geology. The aim of the mission was to ensure a steady supply of raw materials to small and medium-sized companies that manufactured fire-retardant products. Prospecting and exploration in the region helped to find potential reserves of brucite, but practical considerations, i.e. the fact that the Savkinsky deposit location was in a remote, under-developed region, prevented the mining of the mineral at the time.
Some time later, in the 21st century, the management of the Brucite+ Group of companies became interested in these deposits. Aside from the region’s vast quantities of brucite reserves that allow to mine 500,000 tons of the mineral per year, the area is located fairly close to markets in Southeast and East Asia.
As part of the initiative to develop the mineral resources of the Savkinsky deposit, in April 2020, a 21-km long road was built in the Obluchensky District, so that the region being explored could be supplied with necessary materials and equipment. By the middle of May, temporary living quarters for employees had been constructed so that they could reside there in comfort.
That month, drilling began in the region and by March 2021, subsurface exploration of the Savkinsky deposit had been completed. As a result, company staff had collected 10 mineral samples with a combined weight of up to 5 tons. Preliminary estimates showed that high-grade products could be produced from brucite beneficiation.
At present, the physical volumes of assessment are concluded, but the collected data is still being organized. Technological research is conducted in terms of preparation for the development of a feasibility study for temporary exploration conditions.
The new production site is expected to open up new markets due to its location — it is planned to market the high-quality products in South-East and East Asia. The company’s management recognizes the prospects of selling the magnesium hydroxide products to Asian partners, and the construction of the processing plant in the Far Eastern Federal District is designed to reduce the transportation costs to the countries of the region.
