Marnie Pascoe is the General Manager for Major Hazards and Environment at Rio Tinto and a highly experienced geotechnical leader with more than 25 years in the mining industry. Her career spans major organizations including WMC, BHP, and AMC Consultants, where she has held a diverse mix of operational, corporate, and consulting roles. Marnie has worked across the full project lifecycle, from studies and new developments to mature operations, bringing a practical, end to end understanding of mining environments. She has extensive international experience, having worked for over a decade across Central Asia, West and East Africa, and Europe. Her technical expertise covers both underground and surface geotechnical engineering, supported by experience ranging from small-scale projects through to large, multinational operations. Marnie is recognised for leading high-performing geotechnical and multidisciplinary teams, particularly in technical studies (PFS/FS), audits, and due diligence. Prior to her current role, she served as Chief Advisor for Geotechnical Engineering and held director positions with AMC Consultants in the UK, contributing to global technical leadership and capability development.

Peter has more than 40 years of diverse experience in the mining industry, holding executive management and consulting roles in BHP, Rio Tinto, NAB, Hancock Prospecting, Vale, Bechtel, CSR, Talbot Group, and HWE Mining. He spans across a range of commodities including iron ore (hematite and magnetite), coal (coking and thermal), gold, phosphate, bauxite, manganese, nickel/cobalt, chromium, lead/zinc, copper, uranium, magnesium, talc and construction materials. Peter has extensive experience in large-scale mining, rail/port/road logistics and contract mining. His core capabilities are due diligence reviews, banking/finance, developing and implementing complex strategies for managing risk in the mining industry.

Dr. Stephan Arndt is Head of Technology and Innovation for Mining One. The focus of his work is on advanced 3D numerical modelling methods for geotechnical consulting in open pit, underground and cave mining operations. His previous roles include Senior Manager, GEOVIA, and A/Professor and Director Mining & Resources Engineering at Monash University. With over 30 years of experience in advanced simulation methods, he has been mentoring and managing teams specialised in Geomechanics for Mining and Oil & Gas and has been part of studies for major mining projects globally and has served on industry advisory boards and geotechnical review boards.

Dina Kon Mushid is a researcher in Mining Engineering at the China University of Mining and Technology (CUMT), specializing in rock mechanics, slope stability, and geotechnical risk mitigation within open-pit mining contexts. She possesses a Master’s degree in Civil Engineering from Shanghai Jiao Tong University and a Bac+2 degree in Exploration and Mining Geology from the University of Kolwezi, DR Congo. At AAC Mining Executors Group, she significantly contributed to enhancing site safety and operational efficiency by conducting comprehensive geotechnical field assessments, designing customized ground support systems, and implementing real-time monitoring protocols, which markedly reduced slope failure incidents. Her field experience in major operations, such as the Kamoto Copper Company, has further solidified her expertise in practical geomechanics. Her research investigates the application of fracture mechanics to complex rock failure patterns, particularly in the copper-cobalt deposits of the DRC. Her findings have been disseminated in several peer-reviewed journals. Proficient in French and English, with a working knowledge of Chinese, she continues to bridge industry practice and academic innovation in mining geotechnics.

Sameh has been involved in academic work related to supercontinent reconstruction and snowball earth theory at The University of Adelaide. In industry he worked across Australia exploring multiple commodity types including uranium, gold, copper and iron. At Rio Tinto he has held positions in geotechnical engineering and structural geology, implementing his passion for tectonics in the 3D modelling space to optimise open pit operations across the Pilbara iron ore region.
