Geological, lithological, petrographical, geochemical, and geochronological data in the Palaeoproterozoic Richtersveld Subprovince/Magmatic Arc (RMA) of Precambrian basement rocks of the Vioolsdrif Domain in southern Namibia, strongly support linkage

Mining operations are generally reluctant to install high-cost sampling systems at operations that have been functioning for many years. The principal objection to installing appropriate equipment to extract correct and representative samples in proc

This paper investigates the implications for coal supply security for the domestic South African market when faced with weaker export demand. A model is proposed of domestic coal trade via a trading hub which links coal production to consumer markets

In the development of mining projects, there is a period in between commitment of finance and production commencement. Risks are present in various aspects of development such that production start-up could be delayed, thereby affecting the value of

A mathematical model of a multi-product coal mining project is proposed to characterise the economics governing coal production. The model accounts for mining cost variation due to varying production levels, changes in reserves available for extracti

A modified version of the Cobb-Douglas production function is proposed for simulating production costs in resource extraction models. The resulting average cost function is U-shaped with a wide bottom, and as such should be more representative of the

Bulk commodities such as iron ore moving on a conveyor belt represent a one-dimensional lot providing an ideal opportunity for probabilistic cross-belt or cross-stream sampling at regular time intervals. The quality of such materials is measured by t
