About the research project

The transition from a fossil fuel based global energy system to one based on renewable energy sources is required to limit further human induced changes to global climate. This transition requires technologies reliant on critical and noble elements, such as the platinum group elements (PGEs). These elements are either in short supply due to their rarity, or projected increases in demand will soon outstrip supply. Despite the significant annual investment in mineral exploration and decades of research into understanding how and why PGE ore bodies form, the discovery of new deposits is lagging. Furthermore, new and improved methods for modelling the geometric and mineralogical complexities of known PGE ore bodies will help develop more efficient extraction, processing and waste management protocols for the purpose of better ore recovery.

The PlatReef is an important PGE and base metal resource located on the basal part of the Northern Limb of the Bushveld Complex in South Africa. It ranges in thickness from 40 m to 250 m, and comprises texturally heterogeneous pyroxenites, serpentinites and calc-silicate rocks. The reactive footwall rocks of the Transvaal Sequence range from shale, ironstone, dolomite to granite gneiss and play an important and variable role in localising mineralisation through assimilation and alteration processes.

This project will aim to develop and implement workflows and tools for upscaling of data collected at micro to macro scales for the characterisation, quantification and domaining of PlatReef PGE mineralisation and associated rock textures and alteration in order to improve ore extraction and inform future critical element exploration. This will involve the integration of a variety of geologic and geotechnical datasets, including but not limited to petrographic, XRD, mineral chemistry, SEM, ASD, ICP-MS and micro-XRF data. The outcomes of this project will form an integral part of the AMIRA P1249 research effort.
