The saprolite deposit contains 75.6 million tonnes of measured and indicated resources grading 2.47% of nickel and 83 million tonnes of inferred resources grading 2.5%. The Koniambo orebody extends over 20 kilometers long and 5 kilometers wide. On this area of approximately 21 square kilometers has a mineralization of lateritic origin with high contents of nickel.

The laterite profile of the deposit can be described as having a thin layer of rich duricrust that is superimposed on a layer of limonite covering an area of transition finally leading to a layer of saprolite. The quality of nickel, cobalt, iron and various oxide ores varies with depth. The potential economic lateritic material is found mainly along the crest of the orebody and occasionally in the form of scattered pockets on several isolated terraces that extend to the West. Except for four large plates, limonite covering is generally less than 5 meters and it often brings out the trading saprolite.
