The aircraft was carrying £265m worth of platinum, gold and diamonds when the hatch flew open – sending the precious metals plummeting back to earth.
According to the TASS news agency, Russian authorities have recovered more than 170 gold bars weighing 20kg each.
The plane was travelling from Yakutsk Airport – a major diamond-producing region – to Krasnoyarsk. However, the Nimbus Airlines AN-12 cargo aircraft made an emergency landing in Magan after it began haemorrhaging valuables.
Reports suggest some bars of gold were scattered up to 15 miles away from the airport.
