Mineral industry of Seychelles
The mineral industry of Seychelles consists mostly of production of such materials as clay, coral, sand, and stone. Seychelles is not a globally significant mineral producer or consumer. In 2006, imports of mineral fuels accounted for about 27% of the value of total imports.〔(''The Mineral Industries of the Indian Ocean Islands'' ); Yager, Thomas R.; "2006 Minerals Yearbook;" U.S. Geological Survey (October 2007); ''Note: This article incorporates text from this U.S. government source, which is in the public domain''.〕 That same year, Seychelles was estimated to produce about 210,000 metric tons per year (t/yr) of gravel and crushed stone, 93,000 t/yr of granite, and 8,100 t/yr of sand.〔
The main commercial producers of these construction materials are Civil Construction Company Ltd., Gondwana Granite, and United Concrete Products (Seychelles) Ltd.; which are all privately owned.〔
