U.S. based Odyssey Marine Exploration, co-founded by former Bermuda Premier Dr. David Saul, announced that it has successfully recovered approximately 48 tons of silver bullion from a depth of approximately three miles in waters off the south west coast of the Republic of Ireland.
Some of the silver recovered:
This initial recovery of bullion from the SS Gairsoppa, a 412-foot steel-hulled British cargo ship that sank in February 1941, totals 1,203 silver bars or approximately 1.4 million troy ounces of silver and has been transported to a secure facility in the United Kingdom.
After unloading the cargo, taking on fuel and changing personnel, recovery operations will continue and are expected to be completed in the third quarter of 2012. This record-breaking operation has so far produced the heaviest and deepest recovery of precious metals from a shipwreck.
Odyssey is conducting the Gairsoppa project under contract with the UK Department for Transport. Under the terms of the agreement, which follows standard commercial practices, Odyssey bears the risk of search and recovery and retains 80% of the net salved value of the Gairsoppa silver cargo after recovering its expenses. The contract was awarded to Odyssey following a competitive tender process.
Using advanced robotics, Odyssey recovers silver from the SS Gairsoppa shipwreck:
The amount of silver bars recovered so far represents approximately 43% of the insured silver bars, or approximately 20% of the total silver cargo which research has indicated may be on board.
In addition, an estimated 600,000 oz. of insured silver is expected to be found on the SS Mantola, a second modern shipwreck recovery project being conducted in conjunction with the Gairsoppa project.
The Gairsoppa was a merchant ship torpedoed by a German U-boat during World War II. During the War, the UK Government insured privately owned cargo under their War Risk Insurance program. After making an insurance payment of approximately £325,000 [1941 value] to the owners of the silver cargo lost aboard the Gairsoppa, the UK Government became the owners of the insured cargo.
As some sources, including ”Lloyd’s War Losses” indicate a total silver cargo worth £600,000 [1941 value] lost aboard the Gairsoppa, there may have been additional government-owned silver cargo aboard that would have been self-insured.
“With the shipwreck lying approximately three miles below the surface of the North Atlantic, this was a complex operation,” commented Greg Stemm, Odyssey Chief Executive Officer.

“Our capacity to conduct precision cuts and successfully complete the surgical removal of bullion from secure areas on the ship demonstrates our capabilities to undertake complicated tasks in the very deep ocean.
“This technology will be applicable to other modern shipwreck projects currently being scheduled as well as our deep ocean mineral exploration activities. Our success on the Gairsoppa marks the beginning of a new paradigm for Odyssey in which we expect modern shipwreck projects will complement our archaeological shipwreck excavations.”
“The progress on this project is a testament to our world-class team. Our research department developed extensive information about the vessel’s sinking and layout of the ship, and our marine operations team was able to locate both the Gairsoppa and the Mantola shipwreck sites relatively quickly last summer. We assembled the suite of equipment necessary for a successful recovery and conducted reconnaissance dives to plan efficient operations.” said Mark Gordon, Odyssey President and Chief Operating Officer.
“This demonstrates the viability of the business model we have developed to identify and recover the historic knowledge and economic value of otherwise lost government assets.”
Odyssey commenced recovery operations utilizing the chartered 291-foot Seabed Worker in late May after completing a series of reconnaissance dives earlier in the year.
