Geophysical Studies of Mineralised Terrains in Western Australia

Western Australia

State-of-the-art methods for regional exploration targeting place much emphasis on mapping major structures, in particular suture zones between major crustal blocks, in the deep crust and mantle.

Integrated Exploration Platform

Western Australia

Integrated Exploration Platform (IEP) is a GIS based data analytics platform (currently, as a module for ArcGIS) to support mineral explorers operating in Western Australia.

WA_In3D

Western Australia

The WA_In3D project will reduce geological risk by building 3D models constrained by the complete geological database, providing a vastly expanded predictive capacity. These new methodologies will provide for integrated inversion, incorporating uncertainties in exploration datasets using geological misfit functions. This will allow sensitivity analyses to be applied to models to prioritise targets for future data acquisition, further reducing exploration risk.

Research Projects

AngloGold Ashanti ore sorting

Western Australia

Ore sorting is the generic name for a process that takes a run of mine ore stream and rejects a waste component from further processing. The objective is to reduce the volume of low value material undergoing downstream processing, whilst minimising the misclassification of valuable mineral to the waste stream.

Automated Televiewer Image Analysis

Western Australia

Televiewer datasets, acoustic and optical, provide ‘pictures’ of the wall of a drillhole.

Behavioural Analysis in Geoscientific Data Interpretation

Western Australia

Geophysical data interpretation is a highly subjective task and interpreters use various data visualisation methods for enhancement and display in this process.

Development of an automated image analysis method for sedimentary grain size distribution estimation - a feasibility study

Western Australia

Estimation of sedimentary rock grain size distributions in drill core is a task routinely performed by geologists to log changes to the size and sorting of the sedimentary rock grains. This information is valuable for interpreting the primary depositional processes responsible for the emplacement of sediment, their likely geometry and resultant (measureable) flow properties.
