[SMM News: Rosneft Takes Over Russia's Largest Rare Earth Deposit] Rosneft has completed the acquisition of Tomtor, Russia's largest rare earth metal deposit. Located in the northern part of the Yakutia region in Siberia, this deposit is a key project in Russia's plan to boost rare earth metal production. Last year, Russian President Vladimir Putin urged the acceleration of the development of this mining area. Rare earth metals are widely used in the defense industry, mobile phone manufacturing, and EV production. According to Russia's official corporate registration information, Rosneft gained full control of Vostok Engineering, the operator of the project, on May 20.
