Uranium ores of sedimentary affiliation,uacy of uranium resources to supply an expanding nuclear industry and then consider the relative importance of the principal deposit types. The diversity of uranium occurrences precludes a detailed consideration of each deposit type but the reader is referred to Nash .. (1981) for an excellent overv

Ores formed by metamorphism,lso result in important high-grade sources of molybdenum, lead, tin, iron and zinc as well as by-product base and precious metals. Industrial minerals are also worked from deposits formed by metamorphism. Among the industrial minerals are asbestos, wollastonite, magnesite, talc and graphite.

The design and implementation of exploration programmes,sit sought and the geological and geographical environment. Well-organized exploration programmes follow an established pattern beginning with a desk study and ending with the target selection. The target is then evaluated and feasibility studies on the deposit are undertaken. Some companies precede
