This project carried out the regional exploration to investigate the potential economic nickel laterite deposit. The desktop review was purposed to identify the source rocks, climate, topography, structure, tectonic and drainage that can be used as a guide in interpreting the potential nickel laterite deposit enrichment. The source rocks were sampled to identify the rock type that can influence the enrichment. The regional topography was analysed to identify the potential nickel enrichment. The surface mapping and hand auger drilling were undertaken to confirm the potential nickel laterite deposit enrichment. The hand auger drilling were plotted in the area that can intercept a shallow saprolite zone from the surface. As a result, the source rock was identified based on the magnesium and chromite contents that it suggested as lherzolite zone that the nickel grade can increase significantly from the contract zone between the limonite and saprolite that will drop since it intercepted the bedrock. The topography based on the slope analysis was the slight slope area that indicated the enrichment in the spotted zones. The hand auger sapling completed ten holes that intercepted the saprolite zone near the surface. the nickel grade from the hand auger samplings tended to increase towards depth. Furthermore, the lateritization degree was examined based on the ratio between S/SAF that concluded the high lateritization degree for limonite and low to medium for saprolite.
The project valution was carried out using the expected value (EV) method. This method involved mineral probabilities system to determine the geological factor while the npv was computed using the monte carlo simulation to select the best scenario.
