Antoine Cate


Antoine is a structural geology consultant at SRK Toronto. He has completed his B.Sc. and M.Sc in geology applied to mineral resources at Institut Polytechnique LaSalle Beauvais in France. Antoine has completed his Ph.D. on the Lalor Volcanogenic Massive Sulphide deposit under the supervision of Dr. Patrick Mercier-Langevin of the Geological Survey of Canada. He has more than 10 years of both academia and industry field experience in North and South America, Europe, Africa and Australia working on gold and base metal deposits, from greenfield to brownfield exploration. He is also an expert in the applications of data science and machine learning in geosciences, including for prospectivity analysis and automated core logging. Antoine is author or co-author in several peer-reviewed publications, workshops and numerous presentations in economic geology, and in applications of machine-learning in geosciences.

Dr. Antoine Caté is a recipient of the Mountjoy Exchange Award of the Geological Association of Canada. He was awarded the second place at the international Integra Gold Rush challenge as part of the Data Miners team and was involved in the founding of two companies related to the applications of machine learning in the mining industry: Goldspot Discoveries and Geolearn Inc. Antoine’s current work at SRK includes structural field investigation, 3D modelling, and the development of innovative tools applied to structural geology, and mineral exploration.


Penny Stewart


Penny 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 Western Australia that she learnt how geological uncertainty affects our mine planning ability. This experience led her to undertake PhD studies at University of Queensland's JKMRC, where she developed statistical models to predict the mechanical behavior of rock and was awarded the Ian Morley Prize for this work.

In 2015, Penny founded PETRA with the hypothesis that the engineering behavior of rock throughout a mine is best estimated by feeding back 100s of millions of tons of actual mine performance data into engineering models and optimizations. Six years later Petra's AI powered mining software help mining professionals enhance orebody knowledge and optimize the mine value chain.


Steve Sullivan


Steve is a geologist with more than 35 years industry experience in geological modelling and resource management. He has worked across a diverse range of metalliferous and energy commodities throughout Australia and Asia. Steve is Technical Lead for DomainMCF, the Maptek commercial application of machine learning to 3D geological modelling.

He has contributed to several publications, numerous conferences and IOCG workshops.

Jesse is currently a Mineral Resource Manager with Barrick Gold. His focus is to support Nevada Gold Mines to create long-term value by underpinning business development and operational opportunities with world class geological models. He is a passionate member of the Society of Economic Geologists, serving on several committees, as well as being an active mentor.


Liz Stock


Liz grew up in Cardiff Wales, before leaving to complete an MSci Geology degree at Imperial College London. She was fortunate to work on the Red Dog deposit for her Master's thesis assessing the regional breccias to decipher paleo-hydrothermal fluid flow.

Liz went on to study a PhD at the Mineral Deposit Unit at the University of British Columbia. Her PhD was based at the Red Lake Gold Mines, Ontario with the aim of understanding the evolution of the deposit as well as documenting the alteration zonation for future exploration efforts in the district. Liz worked part-time for Goldcorp’s Red Lake regional exploration team every summer as part of her thesis and later consulting work. She also worked part-time at SGS as a mineralogist in the oil and gas division.

Upon completion of her PhD, Liz joined the Teck exploration group as a geochemist. Here, her passion for geochemistry, problem solving, and thrill of exploration was fostered. Liz was primarily responsible for supporting exploration efforts through geochemical, QA/QC and data management expertise across Teck's North American projects, as well as participating in work on Turkish, Irish, and South American projects.

In August 2017 Liz joined the Barrick North American exploration team. Her current role encompasses geochemical and geological support for grassroots to advance exploration stage projects, implementation of new geochemical methods/tools/data assessment and driving discovery through technical leadership.
