Gold mineralization in the Mường Tè area has been mainly discovered during the geological mapping and mineral resources prospecting at 1:200,000 scale (Trần Đăng Tuyết et al, 1994) and 1:50,000 scale (Lê Hùng et al , 2001) of the Mường Tè map sheets. There have been registered approximately 50 ore occurrences and ore mineralization, which are scatteredly distributed along the both sides of Đà River.
On the basis of the research results on distribution law and forming mechanism, the gold mineralization in the study area can be divided into 3 major types:
- Gold mineralization in terrigenous sediments
- Gold mineralization in altered magmatic rocks
- Gold mineralization in loose sediments.
Some gold ore occurrences of the above-mentioned gold mineralization types have been subjected to the detailed investigation in order to determine their size and perspective for the development of mineral resources that may indicate a considerable potential on gold resources of the study area.
