Mongolia chose U.S. miner Peabody Energy , a venture between China's Shenhua and Japan's Mitsui & Co, and a Russian-led consortium as preliminary winners to jointly develop the prized Tavan Tolgoi coal deposit, a senior government source said on Monday. The project, which may require initial investment of more than $7 billion, is seen as vital to kick-start the land-locked nation's economy.

A team of Japanese scientists have found large quantities of rare earth minerals on the bottom of the Pacific Ocean. In a Nature Geoscience article published on Monday, the team said that it looked at 78 sites throughout the eastern South and central North Pacific ranging in depths of 3,500 to 6,000 metres. “We estimate that an area of just one square kilometre, surrounding one of the sampling sites, could provide one-fifth of the current annual world consumption of these elements”

A buildup of volatile gas hampered rescue efforts in one Chinese coal mine and water continued to pour into another as emergency crews raced to reach 42 people trapped yesterday for a second day, officials and state media reports said.
