Sources said the bids, including that of GVK and Essar, are close to $2 billion each. If the bid goes through, this would be the second such coal mine acquisition for JSW Energy which has signed an agreement to acquire Toronto listed CIC Energy. The company has mining cum power complex in Botswana, Africa, for which the company has agreed to pay $418 million.  Hancock Coal is seeking a buyer for two of its coal mines Alpha Coal and Kevin’s Corner, which are located in Galilee Basin in Queensland. The combined reserves of both coal mines can be as high as 7.6 billion metric tons of thermal coal which was used to produce electricity. The life of these mines is almost 30 years.
