Batu Hijau is one of only three mines in the world with total ore tonnage in excess of 1 billion tonnes and gold grades higher than 0.2 gram/tonne. The Batu Hijau project has 6.5 billion lbs of copper and 6.9 million oz of gold reserves with the reserve life of 9 years for gold and 12 years for copper based on the peak production rate in 2010. The NNT mining activities have now entered phase 6.


Within the NNT’s Contract of Works, there are other copper and gold prospects from the Elang and Rinti sites, in addition to the Batu Hijau project. Elang’s copper and gold deposits are estimated to be larger than Batu Hijau’s copper and gold deposites.


PT Dairi Prima Mineral
BRMS owns 80% shares of PT Dairi Prima Mineral (DPM) which is a zinc and lead project in North Sumatra. The total reserves and resources have increased by 104% and 25% respectively based on JORC estimates completed by CSA Global in October 2010 and Mining Plus Pty Ltd. in February 2011. The total reserves consist of 11 million tonnes ore from Anjing Hitam and Lae Jahe sites, which translate into a mine life of more than 15 years.


The concession has one of the highest grades of zinc deposits in the world (11.5% Zn; 6.8% Pb; 7.5 Ag g/t). The total resources size from Anjing Hitam, Lae Jahe, and Base Camp sites (including reserves size) reached 25 million tonnes of ore.


Notable progress was achieved in the effort to commence the first production. In May 2011, the Presidential Decree No 28/year 2011 was issued which allows underground mining under protected forest areas in Indonesia. In November 2011, the Company obtained an In- Principle Approval for underground mining for its concession.
