The Melbourne-based company said the approval was an important milestone on the path to converting the Amaam exploration licence to an exploration and extraction licence.
Tigers Realm subsidiary Northern Pacific Coal Company will now apply for a discovery certificate over the deposit.
If the discovery certificate is awarded, NPCC will be able to apply for an exploration and extraction (mining) licence at Amaam.
The conversion of the Amaam exploration licence to a mining licence would allow NPCC to confirm legal tenure over the deposit for 25 years.
Upon the licence conversion, TIG will move from 40% to 60% ownership of the Amaam coking coal project.
TIG’s has the opportunity to acquire an 80% stake in Amaam following the completion of a bankable feasibility study.
The Amaam project in far eastern Russia has an inferred resource of 177 million tonnes with a further exploration target of 240-380Mt.
