The Jembayan thermal coal operation has been operating since 2004 with substantial year-on year ramp up. For the financial year ending December 2007, Jembayan produced 3.96Mt in 2007. It covers an area of over 12,000ha in East Kalimantan, Indonesia, some 150km north-west of Balikpapan and 80km from the sea.
Straits Resources subsidiary Straits Asia Resources (SAR) completed its acquisition of the mine in 2007 in a deal worth $350m, which was made up of $275m in cash and the issue of 75 million SAR shares to the vendors, representing 6.9% of Straits Asia's enlarged issued share capital.
Jembayan produces two brands of coal: Prangat, which is bituminous and rated 6,000CV ADB; and Jembayan, which is sub-bituminous and rated 5,500CV ADB. Straits Resources says that the purchase of this multi-pit operation has added significant value and prospects to Straits Asia's investments in coal. Less than half the concession area has been explored and Straits Asia intends to complete a major drilling programme during 2008.
