Abstract:

A mathematical model describing the probability for n mines or prospects occurring within an elementary unit (cell) of an area has been referred to as an occurrence model. Estimation of parameters of occurrence models has been plagued by the effect of area delineation on the parameters. Moreover, incompleteness of exploration creates a bias in parameter estimates. This study proposes that when the model is to describe the probability for occurrence of mines or prospects, the appropriate area is a metallogenic unit of mining district scale. Accordingly, this study examined the delineation of ar

Abstract:

Geologic information extraction and integration are the main goals of this study. Tools are designed to aid in exploration for common mineral deposits by intelligently and efficiently processing spatial geological data. Gabor filters, comprising Gaussian-attenuated sinusoidal weight vectors, are used for textural discrimination. A highly non-linear logic operator was designed for "valley", "ridge", edge, and intersection extraction from multispectral images to cover most of the possible local lineament types. A zonation detector (a non-linear logic operator) indicates the presence or absence o

Abstract:

Mineral industry uses potential-field methods to explore shallow-seated resources. As deposits are getting deeper, alternative technologies are needed. Seismic reflection is the only surface method reaching the desired depth. Utilising full-vector field may provide valuable information including better rock characterisation in term of composition, alternations and geotechnical properties for exploration. This research is hoped to add new knowledge along this path and inspire further multicomponent seismic studies in the mineral sector.

Abstract:

This research presents a novel optimisation framework for brownfields exploration drilling. The proposed optimisation methodology has been developed applying geostatistical methods and modern portfolio theory. The use of conditional simulations ensures that geological uncertainty is taken into account, and the application of Markowitz portfolio theory makes drilling funds allocation optimal. The proposed method closes the gap in current research by incorporating the inherent geological uncertainty of an exploration target and mineral economics.

Abstract:

The usefulness of electromagnetic (EM) methods for mineral exploration is severely restricted by the presence of a conductive overburden. Approximately 80% of the Australian continent is covered by regolith that contains some of the most conductive clays on Earth. As a result, frequency-domain methods are only effective for near surface investigations and time-domain methods, that are capable of deeper exploration, require the measurement of very small, late-time signals. Both methods suffer from the fact that the currents in the conductive Earth layers contribute a large portion of the total

Cuttings transportation in micro-borehole annulus in coiled tubing drilling for mineral exploration was studied. The effect of cuttings size and mud properties as well as hole inclination was simulated physically using a flow loop. Computational fluid dynamics was applied to simulate lab experiments and do sensitivity analysis of various parameters. The results show significant differences in cuttings transport response in mineral exploration comparing to the oil and gas drilling applications.

Natural gamma ray spectroscopy has changed little in 30 years. Simulations, laboratory scale models, and field experiments all demonstrate that the natural gamma ray spectrum recorded during borehole drilling can be used to track changes in heavy element concentrations with the Heavy Mineral Index, and it correlates well with iron-rich zones. This research creates a basis for a new generation of safe logging-while-drilling tools plus changes the analysis of airborne radiometrics in the future.

Abstract:

The problems encountered by mineral explorationists when sampling stream sediments for gold were investigated by considering the sparsity of free gold particles and their tendency to form small placers at certain locations in the stream bed. Fourteen 20-kg samples of -5-mm sediment were collected from contrasting energy and geochemical environments in five streams draining gold occurrences in southern British Columbia. The samples were sieved to six size fractions (420 µm to 52 µm) and gold content was determined by neutron activation analysis following preparation of two density fractions us
