Challenger Deep Resources officials have received results from drilling of 25 holes at the KEM production licence of the Barito Coal Project in Central Kalimantan.
Of the 1213 metres of holes drilled, 1087 were open-hole metres, with 125 coring metres. A Jacro 175 and a Down Hole Geophysical logging unit were used in the program with an additional drilling rig expected to reach the site in the near future.
The drilling program’s first phase tested seams 4-8, interpreted from surface mapping and test pitting. Drilling has begun on the interpreted outcrop line of seams 5 and 6, and is currently focused on seam 4; a full 8 separate seams have been intersected with average seam thickness between 0.66 and 0.85 metres. Total package thickness is 8.63 metres. These discoveries may increase the Barito project scope.
Analytical drilling results confirm the coal quality of seam 6 with the previous outcrop samples. Once seam distribution is better understood, according to Challenger, a comprehensive program of further pitting and drilling tests will survey the coal seam quality.
Defining geology and geometry for seams 4-8 will enable feasibility study completion, including open pit optimization and KEM stage 1 production scheduling, said company representatives.
