The program includes three themes distributed across the conference days.
Theme 1 – Discovery
With accelerating demand for most critical minerals and increasing focus on environmental, social and governance (ESG) aspects of mineral exploration and extraction, there is an urgent need for new discoveries of critical mineral resources. While Australia has highly prospective geology for critical minerals, future discovery success will be challenged by the vast size of the continent and, in many cases, limited infrastructure and enabling resources (energy, water, and a skilled workforce).
We also lack fundamental information on the behaviour of critical minerals in nature, and on critical mineral ore systems, both of which are needed to develop effective exploration models.
Presentations in this theme will showcase recent critical minerals exploration successes, new research into understanding critical mineral ore systems, and advances in big data and AI that will shape the future of mineral exploration.

Theme 2 – Characterisation
Critical mineral supply will come from bespoke orebodies (e.g., lithium pegmatites), but also from byproduct of existing base metal mines (e.g., cobalt from copper deposits) or from reprocessing of mine wastes such as tailings.
These sources are incredibly diverse in terms of physical attributes, mineralogy, geochemistry, and metal deportment and distribution. Some are associated with potentially deleterious components (e.g., uranium thorium, arsenic, and/or fluorine) that need to be carefully characterised and monitored.
Detailed characterisation of these ores is essential to improve understanding of ore formation processes, but also to designing flow sheets for efficient, economic and environmentally-responsible beneficiation and processing of ores.
Presentations in this theme will showcase recent advances in methodologies to characterise critical minerals and critical mineral ores, and present case examples of characterisation of ores and processing streams from the sub micron scale to deposit scale.

Theme 3Ìý– Processing
Critical minerals often occur in rocks and ores that are more complex than traditional commodities, causing their behaviour in processing circuits to be harder to predict and often resulting in lower recovery and process efficiency.Ìý
A sustainable and competitive critical minerals industry requires effort to push the existing limits of recovery and grade in ore and waste stream/tailing beneficiation processes. We will need to solve hydrodynamic challenges that can limit recovery/grade to concentrates, and extend the limits of fine particle size recovery of valuable critical minerals. Bioprocessing will also play an increasingly important role in beneficiation and critical mineral extraction.
Presentations in this theme will address the many challenges to industry in processing of critical mineral ores, and outline the latest research developments and improvements to overcome these challenges, thereby allowing progress to more efficient and environmentally-benign mineral processing technologies.Ìý
