Abstract
Realization of good returns in the mining venture needs careful planning, scheduling, design and optimisation of all mining activities which are dependent upon reliable resource estimates. The mineral resource estimation method employed in a deposit thus plays a major role in reduction of risks associated in mining. Indicator kriging, ordinary kriging and inverse distance weighting methods are compared for Monywa K and L deposits. Correlation coefficients in the regression analysis of downhole composites compared with the ordinary kriging estimates for K and L deposits were 0.982 and 0.985 respectively, thus selecting it as the best estimator for the two deposits.
