COAL RESOURCE & RESERVE

PT Bumi Kencana Eka Sakti, a subsidiary of DSS, has > 1 billion tons of coal resources with low and medium-high caloric value.

Currently, BKES is in the finalization of JORC drilling process.

22

Business Prospect and Strategy

Coal industry outlook is especially bright in the next few years, with the Indian and Indonesian market growing very rapidly.- India plans : 74,000 MW coal power plants (requiring

about 100 million tons/year additional coal by 2012)- Indonesia crash program : 10,000 MW of power plants

(requiring about 60 million tons/year additional coal by 2012)

Most of power plants above require coal with CV 5300-5500 kcal/adb of low sulfur and ash, which is the exact specification of PT BIB (a subsidiary of DSS) coal.

2323

Business Prospect and Strategy

High CV coal is getting more difficult to obtain as coal is a non-renewable product. With the market increasing, supply of Indonesia high CV will decrease. At this point, PT BIB (a subsidiary of DSS) will be the primadona of coal mines.

In the very near future and even at present, our coal will be in a very high demand (Following Adaro’s 5900CV, Kideco’s 5600CV, Arutmin’s 5500CV)
