Switzerland’s financial services and manufacturing sector play a major role in the country’s economy while the mining sector is not such a dominant factor. Cement, gypsum, and lime were produced in the country significantly however Switzerland’s mineral resources are limited. There are small iron and manganese deposits in the Jura but no known deposits of coal. A variety of materials is worthy of commercial exploitation. Among them are lime, salt, sand, gravel, clay, and marble. Switzerland's lack of mineral resources is largely counterbalanced by its greatest asset waterpower which is harnessed.
