Entropy, Environment and Resourcesith 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 hig

All mineralized layers are separated by barren sills. Surface and underground gold assay data (11,635 samples) for 371 exploration drill holes representing the

Entscheidung bei partieller Informationistical methods which attempt to integrate some aspects of the available information. However no method succeeds in integrating all of it in a practical and satisfactory way. On the other hand, experience has shown that a good geostatistical study conditioned to a limited but relevant amount of info

Entscheidung bei unsicheren Erwartungen This introduces two problems in the determination of a global mean for the relevant deposit: if the distribution is not perfectly lognormal, an unbiased back transform for log estimates is not known analytically; additionally, even if the back transform is known, the high log variances that appear

Applications of the Concept Of Entropy,Oliver Dubrule has presented an insightful and articulate view of the uncertainty quantification issues facing geostatisticians. These comments are intended to provide additional discussion.
