UPDATE 1-Russia’s Udokan Copper assesses damage after fire

A fire at the operations of Russian miner Udokan Copper on Dec. 30 damaged part of the plant in Russia's far east but left copper concentrate production unaffected, the company told Reuters, adding that it was still assessing the damage. Udokan Copper declined to comment on whether the damage would delay the start of copper cathode production at the plant. A delay to copper cathode production would add to the growing list of supply disruptions in the copper industry including at First Quantum's Cobre mine in Panama and Anglo American lowering its production guidance.
