We are thrilled to announce that PETRA CEO Dr Penny Stewart is a speaker at the SEG (Society for Economic Geology) 2025 Conference on Monday 29th September at the Brisbane Convention and Exhibition Centre.
We are particularly proud that an abstract submitted by a mining engineer and a mathematician has been approved and will be presented at a geology conference on the application of data fusion algorithms and machine learning to increase orebody learning. Learn more about our presentation by reading the abstract below.
The application of data fusion algorithms and machine learning to increase orebody learning
Data fusion ore tracking algorithms fuse geospatial geological data with historical downstream production data to develop site-specific geometallurgy, product quality and material handing models using supervised machine learning.
The term “orebody learning” has been defined to describe the process of developing site-specific machine learning models from production data from across the mine value chain.
PETRA’s presentation will demonstrate the application of orebody learning using a series of six case studies across a wide range of deposits from around the world.
The machine learning models used in orebody learning are typically training using the data associated with 10s to 100s of millions of tonnes of ore mined and processed over one to four years.
Over the past five years, mining operations have extended the application of orebody learning to include optimisation of blasting designs and set points for digging, crushing, grinding and flotation recovery for a range of orebodies including; haematite, magnetite, epithermal gold, and coal overburden removal.
Our presentation will also explore the potential for incorporating optimised designs and set points to further expand orebody knowledge and capitalise on geological data investments for geology driven mine value chain optimisation.

Fun fact! Did you know that PETRA is the ancient Greek word for rock? The image accompanying this post is of Penny at the Natural History Museum in London looking at a section of Rio Tinto hematite from the Pilbara, Western Australia.
