Abstract
Diamond drill data obtained prior to the present production phase form the main basis of this mineral inventory study of the Silbak Premier deposit, with emphasis on post1980 data; limited use of blastnole assays from open pit operations during 1990-91 was essential to our structural analysis. Within a mineralized zone the downhole grade distribution is highly erratic in that single high assays can be contiguous with low grade assays. Thus, a high nugget effect is to be expected. Multiple indicator kriging was selected to take into account the presence of multiple populations for both gold and silver.
