In a separate story, BHP Billiton Mitsubishi Alliance ( BMA ) announced its intention to cease production at the Norwich Park coal mine for an indefinite period. The company has decided against resuming operations but expressed its commitment to maximize redeployment opportunities for the employees till the time Norwich Park is reinstated as a sustainable and profitable low-cost mine. Nevertheless, execution risks like natural calamities, upsurge in oil prices, rising core inflation in the emerging markets and degradation of ore grade clouds such encouraging outlook.
