Molycorp's rare earth reserves jump 36%
U.S.-based Molycorp, Inc., one of the only non-Chinese producers of rare earths, announced today that its proven and probable reserves of rare earth minerals at its Mountain Pass, California facility have increased by 36%, according to a new independent estimate.
The updated estimate, based on the SEC's rigorous "Industry Guide 7" definition of proven and probable mineral reserves, expands Molycorp's reserves to 18.4 million short tons of rare earth ore, at an ore grade of 7.98% and a cut-off grade of 5%. This compares to a previous 2010 estimate of Molycorp's proven and probable reserves of 13.6 million short tons. Both independent analyses were done by SRK Consulting of Lakewood, Colorado, an industry mining consulting firm that specializes in such estimates.
