About the research project
The transition from a fossil fuel based global energy system to one based on renewable energy sources is urgently needed to limit human induced change to global climate. This transition requires technologies reliant on essential and critical elements, such as copper and molybdenum. Copper is required in increasing quantities for low-carbon energy infrastructure, and critical elements are either in short supply due to their rarity or the projected increases in demand will soon outstrip supply. Despite significant annual investment in exploration and decades of research into how and why ore bodies form, the discovery of new deposits is lagging. However, new methods for modelling the geometric and mineralogical complexities of known ore bodies will help develop more efficient extraction, processing, and waste management protocols. Both the discovery of new deposits and more efficient mining practices provide the resources that humanity needs to affect the "clean" energy transition.
The emergence of machine learning as a viable and scalable approach to integrating, analysing, and generating predictions from large volumes of digital data offers new opportunities for modelling deposit location, shape and characteristics. Deep learning systems have shown their predictive power in data-rich environments, although their use in generating models for exploration and mining has been limited, in part due to the requirements of these systems to have extensive and comprehensive training datasets. The volume and coverage of public and private digital geoscience data companies has reached a point where deep learning is a now an emerging option for ore deposit modelling.
This project will utilise a variety of public and private geoscience databases available through the AMIRA 1249 research project to explore and refine the use of deep learning systems for modelling porphyry copper deposits. The outcomes of this project will form an integral part of the AMIRA P1249 research effort.
