The following report by Nikolay Borisovich Karpenko was made on July 15, 2010 at the conference on man-made placers in Magadan. Over the past year, the State Duma considered and rejected the bill on man-made placers. However, in March 2011, the Working Committee of the State Duma Committee on Natural Resources, Environmental Management and Ecology came to the conclusion that it was necessary to return to the discussion of this issue. Accordingly, the report of N.B.Karpenko remains relevant.
The Magadan Region is a large economic region in the North-East of Russia, the infrastructure of which was created to solve an important state task – to replenish the country’s foreign exchange reserves through gold mining. Over the period from 1928 to 2009, about 3 thousand tons of gold, more than 7 thousand tons of silver, 72, 2 thousand tons of tin, 744 tons of cobalt, 82, 2 million tons of coal were extracted from the bowels of the Magadan region. In addition, mining of building materials was carried out.
Currently, about 10.6 tons of gold (67% of the total) in the Magadan Region is mined from placer deposits. Their raw material base is significantly depleted due to long-term operation. The number of small enterprises engaged in gold mining from placer deposits continues to decline annually. The loss of one job in the mining industry entails the loss of several jobs serving it, so maintaining the level of gold mining from alluvial deposits is of predominant social importance. In addition, the development of alluvial gold deposits allows you to maintain the infrastructure of the territory, which contributes and will contribute to the development of other industries in the region.
At present, about 70% of all placer deposits in the region are technogenic deposits.
