Speaker:  Dr Penny Stewart, CEO and Founder PETRA

Abstract:  The seminar will provide examples of how ore tracking and machine learning has been used to build operating models across the mine value chain, and will include how the inspiration for site-specific models using operational data came through my PhD studies at the JKMRC – in fact this work led to me being the recipient of the 2002 Ian Morley Prize.

Bio:  Penny Stewart is a mining engineer and the founder and CEO of PETRA. Penny worked on mine sites for five years before obtaining her Queensland 1st Class Mine Managers’ Certificate of Competency. It was during her time working in the underground and open pit mines of WA that she learnt how geological uncertainty affects our ability to mine to plan. This experience led her to undertake PhD studies at The University of Queensland’s JKMRC, where she developed statistical models to predict the mechanical behaviour of rock, and was awarded the Ian Morley Prize for this work. In 2015, Penny founded PETRA with the hypothesis that the engineering behaviour of rock throughout a mine is best estimated by feeding back hundreds of millions of tonnes of actual mine performance data into engineering models and optimisations. Five years later Petra’s flagship product, MAXTA software suite does exactly that.

About JKMRC Friday Seminars 2021

Welcome to the 2021 Series of the JKMRC Friday Seminars.  The list of presentations will aim to cover a range of topics related to the minerals sector from decision making in exploration, new mineral processing technologies, social licence to operate and mine closure.

The JKMRC Friday Seminars will be presented both in person, at the Indooroopilly Mine Site Lecture Theatre, and also as webinar.  Registration for the webinar is required and can be made via the registration link in each seminar overview.

A large number of past webinars can be accessed on the SMI website: https://smi.uq.edu.au/webinars
