However, of this only 83 million tonnes was classed as a "measured resource" - the most accurate assessment of the available resource. Of this, 11 million tonnes of metallurgical and thermal coal was in the Haju deposit with only a further three million tonnes potentially available but which had not been proven to a high level of confidence. (BHP Billiton provide no details on the breakdown between metallurgical coal and thermal coal). The Lampunent deposit was classed as having a measured resource of 72 million tonnes of metallurgical coal with a maximum potential resource totalling 110 million tonnes and possibly 10 million tonnes of thermal coal.<ref>BHP Billiton, [http://www.bhpbilliton.com/home/investors/news/Documents/2010/100331_Indonesian%20Coal%20Project.pdf "BHP Billiton Indonesian Coal Project - Coal Resource Statement as at 31st December 2009"], March 31, 2010.</ref>
