French energy giant Total says it has made a "significant" discovery of gas off the southern coast of South Africa, reports AFP news agency.
Total's CEO Patrick Pouyanne is quoted as saying that the potential quantities "could be around one billion barrels of global resources, gas and condensate light oil".
South Africa's Mineral Resources Minister Gwede Mantashe said that the discovery was a "potentially a major boost" for the economy which grew less than 1% last year.
