Özet
This paper aims at predicting a primary variable in presence of a secondary variable on the basis of multivariate case. Main idea of the paper is to implement collocated co-kriging technique with a primary and auxiliary variable as a case study. Mostly drilling logs consist of multiple variable records and may be identical to each other. This technique enables multiple variable analyses especially where the secondary data is sparsely distributed. A case study was carried out on determining grade and reserve characteristics of a feldspar deposit in Sarpdere Region (Çine-Aydi{dotless}n-TURKEY). Collocated co-kriging estimation technique was applied to two main feldspar compounds (Na2O and SiO2). Individual experimental variograms and cross variogram of the compounds have been modelled and spatial structure compatibility of the models on the study field were tested by cross validation procedure. Also, grade/tonnage curve graphs and tabulated tonnage distributions at sequential cut-off interval have been calculated.
