The occurrence of metallurgical and high grade coal deposits in Indonesia is controlled by the distribution of bituminous coal deposits (Nas, 2005). For these reasons, high CV rank coal deposits in Kalimantan belong to 2 groups of rocks as follows…

Large, well-developed nickel laterite deposits are common in Sulawesi because ophiolite rocks have been exposed to wet tropical climates for millions of years.

So..... How do we find the next major project in Indonesia, now that we have a simple understanding of how the geological / structural trends influence the formations of both coal & minerals?
