FACTBOX-Guinea's major mining operations

Nov 10 (Reuters) - A reported minerals deal between Guinea and a Hong Kong based investment fund, though unconfirmed, would risk undermining international sanctions against the West African country's military junta, diplomats say.

Guinea's vast mineral resources have attracted major international mining firms, and the West African country is the world's No. 1 supplier of aluminium ore bauxite.

Here are details of some of the country's major mining operations and planned developments.

BAUXITE:

-- Guinea boasts around a third of all known reserves of bauxite, the ore used to make aluminium. CBG (Alcoa (AA.N) and Rio Tinto's (RIO.L)(RIO.AX) Compagnie des Bauxites de Guinee), the world's biggest bauxite exporter, shipped a record 13.7 million tonnes in 241 shiploads during 2008. The company accounts for some 80 percent of Guinea's mining income, which was worth $149 million in 2007.

Bauxite production is as follows (capacity in brackets): Compagnie des Bauxites de Guinee/Boke Mine 13.18 mln (15 mln)

Alumina Company of Guinea/Fria-Kimbo Mine 2.8 mln (2.8 mln)
