Saudi Arabia and Sudan to explore Red Sea basin for gold and silver

Oct 10, 2011 12:00 AM

Sudan and Saudi Arabia plan to produce within three years gold, silver and copper in large quantities from the bottom of the Red Sea, trying to execute a project in planning for almost four decades, a senior Sudanese official said.
Both countries, which lie across each other in the Red Sea, have been sounding out since the mid-seventies on how to exploit large mineral deposits suspected to be 2,000 metres below sea levels.

A German firm first analysed in the seventies the Atlantis II basin which is located roughly half way between the Saudi port city of Jeddah and Port Sudan, the biggest port on the African country.
Using that data, both countries -- which agreed long ago to jointly explore the potential of the Red Sea -- now plan to start production in 2014 using special drill ships, said Abbas Al Sheikh, undersecretary in the Sudanese mining ministry. Sudan will explore the basin with Saudi firm Manafa International which has formed a joint-venture with Canadian firm Diamond Fields International for the task.

"It's a lot," Al Sheikh said on the sidelines of an industry conference in Port Sudan when asked how much both countries planned to produce from there.
Based on past estimates the basin stretching some 60 sq km contains 47 tons of gold, 3,750 tons of silver, 1.89 mm tons of zinc plus around 425,000 tons of copper, a Sudanese ministry study says. The rock in the basin "indicates that sediments in some parts of the Atlantis basin may attain a total thickness of up to 160 metres," Diamond Fields says.

Al Sheikh declined to say how much the project would cost, saying only it had now become viable after gold and copper prices have risen strongly: "It is very costly...but now gold and copper prices are high. It's expensive."
Diamond Fields said more than $ 70 mm had been spent to date by Saudi Arabia alone on research.

Industry experts said extracting the minerals from the sea bottom would be difficult and expensive, putting a question mark over the production date. Processing the minerals at a plant would cost $ 200 mm or more.
"There are significant technological challenges," said Tucker Barrie, a Canadian mining consultant attending the conference. The operation would need around 200 workers on rotation on sea plus 300-500 people working on land at a metallurgy plant.

Barrie said copper would be the most interesting mineral to extract from the deep-water basin: "Copper is the most value resource... . From the size it is all copper."
Neither Saudi Arabia nor Sudan had a copper smelter to process the minerals, Barrie said. Building one would cost around $ 2 bn which would make sense instead of taking the copper somewhere else for processing.

Al Sheikh said both governments had not yet decided where to process the extracted minerals.
Sudan is expanding its minerals and gold production to compensate for the loss of most oil reserves to newly-independent South Sudan.
