Underwater footage of the SS Gairsoppa
A shipwreck containing 200 tonnes of silver worth about £150m has been found in the Atlantic - the largest haul of precious metal ever discovered at sea.
The SS Gairsoppa, a UK cargo ship sunk by a German U-boat in 1941, was found by US exploration firm Odyssey Marine.The firm will retain 80% of the cargo's value under the terms of a contract with the Department for Transport.
Only one person from the 85-strong crew survived the torpedo attack as the ageing steamer tried to reach Ireland.
The vessel was on its way back to Britain from India when it ran low on fuel in stormy weather, and tried to divert to Galway harbour, but it was spotted and sunk by the German submarine.
'Robotic submarines' Three members of the crew survived in a lifeboat and reached the Cornish coast two weeks later, but two died trying to get ashore.
The wreck of the 412ft ship was found this summer nearly 4,700m below the North Atlantic, 300 miles off the Irish coast, but it was only confirmed as SS Gairsoppa last week.
"Now we're hard at work planning for the recovery phase.
"Given the orientation and condition of the shipwreck, we are extremely confident that our planned salvage operation will be well suited for the recovery of this silver cargo."
SS Gairsoppa settled upright on the seabed with its cargo holds open, which means remote-controlled robotic submarines should be able to retrieve the bullion.
Work would begin in the second quarter of 2012, Odyssey said.

SS Gairsoppa - a brief history
- Steamship first used in 1919 by the British India Steam Navigation Company
- Involved in commercial shipping in the Far East, Australia and East Africa
- Enlisted in the service of the Ministry of War Transport in Jan 1941
- On her final voyage from Calcutta, India she was loaded with nearly 7,000 tonnes of cargo - including pig iron, silver, and tea
- On Feb 17, 1941, U-boat 101 torpedoed the Gairsoppa causing her to sink
- Of the 32 crew members who boarded lifeboats, all perished except for one survivor
The seven million ounces of silver on the ship is a mixture of privately owned bullion insured by the UK government and state-owned coins and ingots.
Researchers used records including insurance documents from Lloyd's War Losses Register to work out how much was on board.Odyssey president Mark Gordon said one set of documents suggested the silver bars may contain 2.5% gold as well, which he described as "an added bonus".
The marine archaeology and exploration company said it was "highly unlikely" any human remains would be found, given the age and depth of the wreck.
Odyssey's chief marine archaeologist Neil Dobson said: "Even though records indicate that the lifeboats were launched before the ship sank, sadly most of her crew did not survive the long journey to shore.
"By finding this shipwreck and telling the story of its loss, we pay tribute to the brave merchant sailors who lost their lives."
Odyssey said it had taken on the risk and expense of the complicated search, cargo recovery, documentation, and marketing of the cargo.
The merchant ship belonged to the British India Steam Navigation Company, and was ordered into the merchant navy fleet at the outbreak of World War II.
On her final voyage from Calcutta, India she was loaded with nearly 7,000 tonnes of medium and high-value cargo, including pig iron, tea, and the large quantity of silver.
Of the 32 crew members who boarded lifeboats after the attack, all perished except for one survivor.
Second officer Richard Ayres reached shore at the Lizard lighthouse in Cornwall 13 days after the sinking.
He was made an MBE for his efforts in trying to save his fellow sailors, and lived until 1992.
A Department for Transport spokeswoman said: "The contract for the salvage of the SS Gairsoppa was awarded by competitive tender in accordance with government and departmental procedures.
"While we do not comment on the specifics of such commercial arrangements, Odyssey Marine Exploration were awarded the contract as they offered the best rate of return to HMG [Her Majesty's Government]."
