UPDATE 1-Gambia shuts down Carnegie Minerals offices -sources

(Adds details)

BANJUL, Feb 12 (Reuters) - Authorities in Gambia shut down the offices of British-based miner Carnegie Minerals CGMR.L on Tuesday, almost a month after President Yahya Jammeh ordered the firm to clarify its activities, police sources said.

The authorities had warned AIM-listed Carnegie, which has two major mineral sands projects in Gambia and neighbouring Senegal, that it may not be correctly reporting the quantity and value of its mineral exports from Gambia.

The company said last month it had suspended its operations pending a government inquiry but said that it firmly believed it had met all the terms of its mining licence.

The police sources said the managing director of the company had been detained for questioning and that its offices in Sanyang, some 50 km (30 miles) west of the capital Banjul, had been sealed off. (Reporting by Pap Saine; Editing by Nick Tattersall and Michael Roddy)
