Pakir Jainlabuddin Abudul kalam is taken away by the time on 28th July
in Morning Hours. He mixed with time like a warrior, delivering a
seminar at Shilling of Meghalaya.Stochastic modelling based on
autocorrelation function ('acf') approach, although has its merits,
still does not take into consideration the structural aspects of
mineralization - most important being the geometry or the location of a
sample in a mine. This problem has been addressed by considering the
variable: grade/accumulation as a Regionalized Variable but not as a
Random Variable. The variation around a fixed surface reflected by assay
values may not necessary be considered as random. These could be due to
real variations with-in the variable. Hence tru-ctural analysis which
can be reflected by variographic models can be employed. Kriging which
utilizes the variogram models, leads to Best Linear Unbiased Estimates
in the stationary case.In order to make proper estimation of mineral
value properties, a study of the underlying distribution is essential
