Two major series of crosscutting dikes (Dk1a and Dk1b) are common in Sungun porphyry deposit. Those are varying compositionally from quartz monzo-diorite to granodiorite. About thirty percent of the sungun stock is filled by Dk1a and Dk1b dikes. Presence of dikes will cause lots of errors in copper content estimation, so determination of dikes is very important. Ten percent of dikes volume could be identified through drawing strings and correlation between boreholes. For estimating and determining the other part o...

In the detailed exploration and reserve estimation, with separating the alteration (as the controller of the grade) in ore reserve and estimating the reserve in each alteration, the estimation variance will decrease and the accuracy of the estimation will increase. This paper tries to quantify and separate the alterations using discriminant analysis, a multivariate statistical method, and distribute them through sequential gaussian simulation in the Sungun copper deposit. A simple linear discriminant function tran...
