LONDON, Feb 13 (Reuters) - The cyclone that hit Madagascar this week has halted production at cobalt and nickel miner Ambatovy, traders said, adding that a prolonged outage could lift prices of the battery material.

Ambatovy, owned by Japanese trading house Sumitomo Corp 8053.T and state-owned Korea Mine Rehabilitation and Mineral Resources Corporation (KOMIR), produced around 28,000 metric tons of nickel in 2024 and roughly 2,500 tons of cobalt.

Traders said exports were likely to be disrupted as Madagascar's main port Toamasina was hit badly.

Ambatovy and Sumitomo did not reply to requests for comment.

Ambatovy produces nickel and cobalt briquettes, which are easily crushed into small particles and dissolved in sulphuric acid to make sulphates, used for electric vehicle batteries.

Prices of cobalt, also used in the aerospace industry, are holding steady around OCBc1 $26 a lb. They have risen 160% since top producer Democratic Republic of Congo imposed an export ban in February last year. It lifted the ban in October and introduced annual export quotas.

Analysts expect global cobalt mine supplies at around 285,000 tons this year, with around 70% coming from Congo.
