Maximising the value of a drilling program: Case study in a challenging environment
10:35 AM - 10:55 AMBiography
Anne-Audrey Latscha is a Principal Geologist at Rio Tinto Iron Ore, in Perth (Australia). After graduating of a Bsc (Hons) in Geology - Geochemistry from Louis Pasteur University (Strasbourg, France) and a Msc in Hydrogeology from Joseph Fourier University (Grenoble, France), she has been working for 6 years as a Hydrogeologist Consultant in France, before moving to Australia 15 years ago where she joined the Rio Tinto Iron Ore Resource Development Team. She occupied diverse roles in Geosciences mostly as a Groundwater Modelling Specialist, and from Evaluation Geologist to Superintendent Geological Modelling & Resource Estimation and more recently she is a Principal Geoscience in the Resource Geology and Data Management Team, working mostly on technical and business improvement projects with a focus on the development of tools and practices to assist in characterizing Resource Uncertainty.
The diversity of roles at different stages of the Resource Definition Value Chain gave her a comprehensive overview of the resource definition practices in Iron Ore. She is passionate by any opportunity for continuous improvement in OBK practices and finding alternate ways to improve the Mineral Resources and Ore Reserves definition.

Q&A + Discussion
11:50 AM - 12:10 PMBiography
Prof Bruce Harvey
Committee Member
AusIMM Social and Environment Society
AusIMM Social and Environment Society Presentation
12:10 PM - 12:15 PMBiography
Bruce’s career has spanned 40 years of worldwide field experience in the mining industry. In his early career as a geologist Bruce developed an affinity for working with land connected peoples and set up Rio Tinto’s first exploration access agreements with Aboriginal people in Australia. For the last 20 years Bruce has been at the forefront of developing Social Performance as a new professional discipline in the extractive sector. For seven years Bruce was Global Practice Leader – Communities and Social Performance at Rio Tinto, leading a small team of achievement and distinction. As well as his role as an Adjunct Professor at the SMI, Bruce is currently the Principal of a boutique consultancy, resolution88, specialising in ‘Social Licence’ solutions for the extractive sector.
Well published, Bruce maintains that earning a Social Licence is essentially a matter of cultural recognition and economics. Extractive companies want to operate in peoples’ backyards with irreversible changes to natural and social landscapes, some induced by industrial development and some occurring anyway. In return, local people want economic opportunity whilst preserving their idiosyncratic cultural norms and local environmental integrity. Bruce believes strategy is important, but that lack of individual and company capability is the weak link in answering the Social Licence challenge. He believes that many companies attempt to earn social endorsement through public relations approaches at great expense with little success. Instead, he advocates and teaches an approach based on mobilising the practical skills of the extractive sector aligned to the intergenerational aspirations of host communities. Bruce has a unique ability born of many years’ field experience and front line social innovation to reflect, research and teach in the field of Social Licence and Social Performance.
