PRAGUE, Jan 28 (Reuters) - Czech mining group New World Resources (NWR) <NWRS.L> <NWRSsp.PR> warned of a drop in output of more profitable coking coal in the past year, sending its shares down more than 4 percent on Friday.
Although the miner, owner of the Czech Republic's largest hard coal mines, said it had met 2010 production targets overall, the proportion of coking coal in the sales mix was lower than expected and this had hit full-year revenue.
NWR said the shortfall was caused by lower production at one of its mines and was only partially offset by an increase of thermal coal production at another mine.
NWR said coking coal output would not rebound until later this year.
"The company expects an increase in coking coal volumes towards the end of 2011 and a subsequent rebalancing of the product mix towards coking coal in 2012," it said.
NWR shares fell 4.4 percent to 284.1 crowns by 0839 GMT, but remained off lows hit earlier this month. The stock has risen 46 percent in the past year, boosted by rising commodity prices and outpacing a 5 percent rise in the Prague bourse's PX index <
>."NWR's share price is currently well above our target price and the worse outlook for production and sales mix substantially reduces potential for an increase of the target price. We expect negative reaction in following days," Ceska Sporitelna analyst Petr Bartek said.
The bank has an NWR target price of 253 crowns.
NWR produced 11.4 million tonnes of coal in 2010 and 1 million tonnes of coke. In the current year, it said it expected production of 11 million tonnes of coal and 800,000 tonnes of coke.
NWR also reported price increases which analysts said were roughly in line with market thinking.
It said the average price for first-quarter contracts of coking coal -- comprising the 20 percent of volumes which had not already been contracted for the fiscal year ending March -- would rise 7 percent over the fourth quarter to 165 euros per tonne.
NWR had sold the other 80 percent of coking coal volumes in yearly contracts last year and said the price remain unchanged at 163 euros per tonne.
NWR also said it had agreed a 13 percent rise in the average price for thermal coal sales in 2011.
External sales should reach 10.3 million tonnes of coal, split evenly between coking and thermal coal, and 720,000 tonnes of coke in 2011. (Editing by Dan Lalor and David Holmes)
