Nguyen Van Hoai suggests in a 1992 IAEA report that in Vietnam...(pp. 115 to 117), where uranium exploration started before the National Independence (from the French, Soviet Union and China), a number of occurrences were discovered. They belong to the sandstone, vein, volcanic, metamorphic and superficial deposit types. In addition, some coal seams have been found to be uraniferous. Uranium resources have been classified as follows: 200 tonnes U as EAR-I, recoverable at costs between US$ 80 to 130 per kg U, 200 tonnes U as E and R-II, recoverable at costs between US$80 to 130 per kg U, and 180,000 tonnes U as Speculative Resources, of which 100,000 tonnes are believed to be recoverable at costs of below US$ 80 per kg U and the remaining 80,000 tonnes at above US$ 130 per kg U.These are all preliminary numbers but the low cost reserves are likely to be much higher than known in early 1990s IAEA estimates.
The known uranium mineralization in Vietnam exhibits distinct characteristics as regards the distribution in space and time of formation. These features include the following ...
- 1. The uranium occurrences known as of the end of 1990 are scattered over the whole territory of the country. However, some more significant concentrations occur in the central and northern parts of Vietnam.
- 2. The age of the known uranium mineralization ranges from Proterozoic to Quaternary. However, those occurrences with a higher potential are of Mesozoic age.
- 3. The ore grade in the known occurrences ranges from 0.05 to 1.0 % U.
- 4. The occurrences and prospects belong to the following deposits types ... - sandstone - vein - volcanic - metamorphic - coal - superficial in younger sediments.
The Vietnamese Government encourages the co-operation with foreign companies based on the principles of equality and mutual benefits as stipulated in the Foreign Investment Law.
