It has been reported the warship was carrying the 5,500 boxes filled with gold bars along with a haul of 200 tonnes of gold coins.
Shinil Group estimates the gold to be worth 150 trillion won ($176 billion) in today’s value.
The company plans to raise the wreck in October or November.
It said half of any treasure found would be donated to the Russian government.
Part of the remaining treasure would also help fund infrastructure projects in north east Asia such as a new railway
linking South Korea and North Korea.
