Optimise mining operational decisions with

Hello, we’re PETRA.
We build mining software that’s used by hundreds of sites worldwide. And we’re serious about creating reliable prediction, optimisation and decision support tools for mining professionals.

Our AI-Powered Products & Services

Recreate your sites best day, every day


Discover enterprise-grade orebody learning software for value chain optimisation. Data fusion ore tracking is at the heart of all MAXTA applications.


Achieve digital mine-to-mill or pit-to-port optimisation by using your best performing blast designs for your site’s unique geological variability.


Increase the accuracy of mine planning by adding orebody learning variables to your geological block model.


Increase the accuracy of mine scheduling inputs and dispatch to improve load and haul efficiency.


Optimise by modelling your whole plant and dynamically adjust set points for variable plant ore feed.


Avoid costly breakdown events using platform agnostic machine health and predictive maintenance software.

Direct services tailored to your requirements

Digital projections of rock testing

We run ROCKRay for you to fill in gaps between rock testing samples to provide add continuous rock testing results to your drill hole database.

Digital pit-to-port

We run MAXTA digital pit to port applications for you for a fixed period.

Digital mine-to-mill

We run MAXTA digital mine to mill applications for you for a fixed period.

Resource and engineering block modelling

Let us build resource and engineering block modelling for you using ROCKRay in your preferred block model format and modelling environment.

MAXTA Integration Validation Services

Ensure the correct interpretation and treatment of the models generated by MAXTA and to avoid any errors or wrong interpretation of the models in downstream processes, systems or applications.

Why Petra?

We empower mining professionals to continuously improve and make better decisions by prioritising geological uncertainty. We aim to minimise frustration for engineers who are required to design and plan with inputs that have a high level of variabilty.

Our key solution is our proprietary ore-tracking which fuses operational performance with geology to provide robust inputs for engineering.
