Abstract
The estimation in this paper uses threekinds of block models of nearest neighbor polygon, inverse distance squared and ordinary kriging. The techniquesare weighting scheme which isbased on the principle that block content is a linear combination of the grade dataor the sample around the block being estimated.The case study in Pongkor area, here is gold-silver resource modeling that allegedly shaped of quartz vein as a hydrothermal process of epithermal type. Resources modeling includes of data entry, statistical and variography analysis of topography and geological model, the block model construction, estimation parameter,presentation model and tabulation of mineral resources.Skewed distribution, here isolated by robust semivariogram. The mineral resources classification generated in this model based on an analysis of the kriging standard deviation and number of samples which are used in the estimation of each block. Research results are used to evaluate the performance of OK and IDS estimator. Based on the visual and statistical analysis, concluded that the model of OKgives the estimationcloser to the data used for modeling.
