A Russian cargo plane with ten tons of silver, platinum and diamonds lost part of its cargo worth about $368 million after taking off from Yakutsk airport on Thursday.
According to Airlive.net, the Nimbus Airlines Antonov An-12 cargo suffered problems during takeoff. Part of the cargo fell out of the hold all over the runway.
The report said the plane then dropped some bars of silver as far as 26 kilometres from the airport.
The crew decided to land at the nearby airport of Magan, some 26 kilometres north-west of Yakutsk.
Police sealed off the runway and a vast search is underway.
Technical engineers at the Yakutsk airport who prepared the plane for takeoff have been detained.
The cargo, which was en route to Krasnoyarsk and further to Kupol (Dome) mine, is reported to be owned by Chukota Mining and Geological company; 75 per cent of the private company is owner by Canadian Kinross Gold.
