Amber, gold, kaolin, and manganese are among the 11 mineral and groundwater deposits that go up for electronic auction Dec. 23, reports the State Service of Geology and Subsoil. The next auction will offer about 50 more sites, according to Roman Opimakh, head of the agency, known as Gosgeonadr. In the first year since electronic auctions became mandatory, the price of licenses increased 15-fold, earning the state about $28 million, Opimakh says.
