Chapter 2. The resource database

Настоящий справочник в отличие от предыдущих сборников ВГФ, изданных по видам минерального сырья, составлен по отдельным странам капиталистического мира
Цель справочника — в краткой, сжатой форме ознакомить широкий круг читателей с состоянием запасов и добычи минерального сырья в капиталистических странах.

Risk in project evaluation involves the probability of estimates failing. There are few more risk prone businesses than mining. Burmeister (1989) reviewed 35 Australian gold operations which were initiated in the period 1984 to 1987 and found that two-thirds of them had not achieved targeted gold production in the first full year of operation. For those that did exceed target, the overriding reason was a higher than anticipated plant throughput. Only two out of the 35 achieved their projected recovered grade. Burmeister observed that the reasons for the shortfall in grade included excessive dilution, inappropriate estimation techniques, inadequate geological interpretation, unreliable assays and inadequate drilling.

Applied Mineral Inventory Estimation presents a comprehensive applied approach to the estimation of mineral resources/reserves with particular emphasis on

The geological basis of such estimations

The need for and maintenance of a high-quality assay data base

The practical use of a comprehensive exploratory data evaluation

The importance of a comprehensive geostatistical approach to the estimation methodology.

Эту книгу можно назвать аналитической летописью геологической службы и проблем минерально-сырьевой базы России времен кардинальных политических и экономических преобразований конца XX столетия.
