3. PROJECT DESCRIPTION
3.1 General Background
GBP is one of six coal projects operated by PT Bayan Resources Bayan. A separate Coal Resource and Reserves report is being prepared for each of the Bayan coal projects.
3.2 Location and Titles
GBP is located in the province of East Kalimantan, Indonesia, and consists of two separate concession
blocks, GBP Block 1 to the east and GBP Block 2 to the west as shown on Figure 1. The terrain is relatively flat to undulating and lightly wooded with sparse settlement. There are several nearby villages. The deposit is 30 km
south of the Mahakam at the nearest point.
GBP is a second generation Coal Contract of Work or CCOW issued by the Indonesian Government which covers a total area of 24,055 Ha, of which Block 1 covers an area of 8,365 Ha Block 1 = KW.05PB0165.
The CCOW covers the area of mining and stipulates various government payments and conditions that need to be met as part of the contract.
3.3 Mining Operations
There are four deposits in the lease area: Keham, Cilong, SP and Mantan. This report only includes Keham and Cilong as only limited data is available for the Mantan and SP Blocks. It is understood that mining is
to commence in Keham block in 2009. The current planned mine life is 4 years. The proposed mining method can be described as “multi seam, moderate dip shallow open cut coal
mining using truck and shovel equipment in a haulback operation.” After the initial box cut waste has been hauled to ex-pit dumps, waste will be hauled back into the mined out area, when pit room is available and the
dump area will then be rehabilitated. The proposed open cut operation will use hydraulic excavators and trucks to mine the coal and waste. The run-of-mine ROM coal is not washed but is to be crushed to produce a semi-soft
coking export coal.”
3.4 Infrastructure of Site Facilities
At the Keham Block it is proposed to utilise the facilities and infrastructure of KCB, including offices and a camp with associated haul road, barge loader, power and water supply. The Cilong Block will require the
construction of separate facilities and a new haul road to the proposed new barge loader on the Mahakam River. There are several towns within the surrounding area from where operators will be sourced.
3.5 Transport and Coal Handling
Coal from Keham will be trucked approximately 75km from the pit to the KCB barge loader on the Mahakam River via the KCB haul road and Cilong coal will be hauled approximately 30 km to a proposed new
barge loader. The coal will then be barged approximately 290 km from the KCB barge loader and 360km from the new Cilong Barge Loader to the Balikpapan Coal Terminal.
3.6 Marketing
The coal is very high energy relative to other Indonesian export coals and can be sold as a semisoft coking coal. It is therefore very suited to blending or selling at a premium to the benchmark price. A premium
has been factored into the Coal Reserve estimates.
4. GEOLOGY, COAL QUALITY AND COAL RESOURCE ESTIMATE
4.1 Geology Overview
The resources are high volatile bituminous coal occurring in the Lower Miocene age Pamaluan Formation. The deposits are relatively small multiple-seam deposits. A total of four coal seams and sub-seams
or seam splits have been identified in the Keham Block and they range in thickness from 0.1 – 2.0 m. In Cilong Block three main seams and multiple sub-seams or seam splits occur from 0.2-2.5 m in thickness.
A-20
The generalised stratigraphic column showing seam nomenclature is on Figure 2. Average seam thickness per seam by block is shown in Tables 4.1 and 4.2 below.
The seams are folded around a north plunging syncline, with dips of 10-15 degrees steepening towards
the flanks of the syncline. A number of representative cross-sections for each block are shown on Figure 3 and Figure 4.

4.2 Coal Quality
The coal is very high energy average 7,210 kcalkg gar and medium ash 6-7 adb bituminous coal with variable sulphur content 0.4-3.3 adb with an average of 1.5 adb at Keham and 1.2 adb at Cilong.
Average coal qualities for both blocks are given in Tables 4.3 and 4.4.
A number of drill holes are “touch” cored and samples were submitted for analytical testwork, which typically included Total Moisture, Proximate Analysis, Total Sulphur, Calorific Value and Relative Density test
work. “Touch” coring results in some coal loss at the seam roof, therefore in thinner seams there may be a degree of sample bias.
