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)

Bauxite production 2008 19.78 mln * RUSAL's Friguia plant refines bauxite to alumina, with a total projected 2008 production of 527,000 tonnes of alumina.

* Alcoa and Rio Tinto are considering adding an alumina refinery to their Guinea bauxite joint venture.

* Toronto-listed Global Alumina (GLAu.TO) is building a new 3.3 million T/yr alumina refinery, but has delayed start-up by two years to 2011 and raised its cost forecast 35 percent to $4.3 billion.
