What is Orebody Learning?

Orebody Learning is a process that enables operations to learn about their orebody directly from operational experience. It is performed using PETRA’s proprietary digital twin technology: Data Fusion Ore Tracking & Machine Learning. 

Image showing questions about what is orebody learning.


Orebody learning provides:

  • Site-specific models using a mine’s own data
  • High granularity block-by-block predictions
  • Updated block models as soon as new operational data has been provided
  • File formats which are platform agnostic, designed to connect with in-house or third party data platforms


The problem it aims to solve

Previously, orebody knowledge was limited to:

  • Grade & product quality
  • Geometallurgy
  • Geotechnical characterisation


The solution

Many mining operations suffer from the inability to learn from experience, orebody learning using digital twin technology aims to bridge this gap.

Expanded orebody knowledge provides information about:

  • What is the best way to process the ore
  • What is the best way to blast the ore
  • How to be more energy efficient
  • How to predict material handling properties
  • How to predict recovery


Orebody learning powers PETRA products and applications

Considered the heart of all PETRA solutions, orebody learning allows us to create decision support tools to predict, simulate & optimise using a mathematical model of how your mine works.


Customer benefits

  • Increase profit margin/ recover benefits faster
  • Optimise the value chain for geological variability
  • Support operational decisions based on data driven models
  • Integrate with existing systems(software) and workflows
  • Get more value from existing data
  • Create a repository of geology linked to performance
  • Create 10’s of thousands of data records


How does this compare to other solution providers?

  • They rely upon 20th century empirical models for example Orica’s IES.
  • Provide low granularity 3D models using spatially limited rock testing data
  • Provide forward only predictions without a feedback loop
  • Force mining companies to use their data platform
  • Don’t use digital twin technology to improve orebody knowledge
