Sukhoi Log mine Wikipedia
During the 1990s a proposal was made to mine Sukhoi Log by the semi-private Russian company Lenzoloto with the British Virgin Islands company Star Technology Systems (previously known as Green Applied Systems Limited). Funds toward the venture were raised from the Australian Stock Exchange company Star Mining (previously known as Central Mining Corporation, now Argonaut Resources). Various legal, bureaucratic and political problems delayed progress. Sukhoi Log was the subject of a special hearing held by the State Duma's Security Committee under the watchful gaze of hardline communist Viktor Ilyukhin to investigate threats to Russia's national security from this "shadowy" Australian company. The Australian company wrote off $127 million on the failed venture after Russian courts overturned decisions by Russian politicians.
