Making the block model must be very careful to generate a detailed geological interpretation that can be converted into a model to be known deposition of a material excavated in the area. The purpose of this study was to determine the model of the condition of lateritic nickel deposit in the form of 2- dimensional and 3-dimensional by using Surpac software applications. By way of inputting the database consists of the assay data, collar, survey, and lithology. Model 2-dimensional cross-section or cross section is divided into eight cross-section of 37 drill point. 3-dimensional model image overburden does not include all of the drill point means the block models produced uneven. 3- dimensional image of ore models all include all of the drill point. For the three-dimensional model image bedrock there are several levels of Ni in the bedrock nearing> 0.9% but keberedaannya very
small. Cross section of the cross section line 1 to line 8 it appears that not all boreholes have a zone over burden and bedrock zones. Picture 3-dimensional model of over-burden no means covers all of the drill point block models produced uneven, this is due to the Ni content level at this stage of drilling has been over> 0.9%
