UPDATE 1-CAMEC H1 sales up 90 pct, won't divest coal assets

* CAMEC H1 revenue jumps 90 percent

* Halts plan to divest S.Africa/Mozambique coal assets

* Reviewing exploration spending

Nov 6 (Reuters) - London-listed Central African Mining & Exploration Co Plc (CAMEC) (CFM.L) said on Thursday its first-half revenue jumped 90 percent on higher sales of copper and cobalt.

The Africa-focussed miner, with interests in copper, cobalt, coal, platinum, fluorspar and bauxite, said first-half revenue rose to $184.5 million, helped by average monthly sales of 422 tonnes of cobalt and 867 tonnes of copper sales, both well above year-earlier levels.

The company said it halted plans to divest its coal assets in Mozambique and South Africa into a separately listed company, as it believed the move was not appropriate in the current market, but it was reviewing all options.

CAMEC, which had a net cash position of more than $48 million as of Sept. 30, said it was reviewing its exploration spending in view of the current capital market turmoil and the recent fall in commodity prices.

Regarding its share buyback plan, the company said it was currently in a close period and was unable to purchase its own shares, but it would review the position after it announces interim results.

CAMEC said its operations in the Democratic Republic of Congo's Katanga province had not been affected by unrest in another part of the country.

At 1020 GMT, CAMEC shares were down 3 percent at 8 pence. (Reporting by Kumar Alagappan in Bangalore; Editing by Mike Miller)
