Keynote Speakers

Mine Closure 2022
4-6 October 2022 | Brisbane, QLD, Australia

Keynote Speakers

Brian Ayres
Acting Manager of Integrated Closure Planning – Legacy Assets, BHP

Brian is the manager of integrated closure planning for BHP Legacy Assets based out of BHP’s Saskatoon, Saskatchewan office. He works with may stakeholders to achieve optimised closure outcomes at BHP’s 23 non-operating sites in North America. Brian has a master’s degree in geoenvironmental engineering and over 26 years’ experience in the mining industry, including four years with Orano (formerly COGEMA and AREVA), 15 years with O’Kane Consultants, 5.5 years with SNC-Lavalin, and 1.5 years with BHP Legacy Assets. Over his career, Brian has been involved with mine closure projects and support studies across a wide array of climatic settings, ecosystems, and jurisdictions across North America, Australia, and New Zealand. He is an SME in the field of mine waste storage facility final landforms and cover systems, and has published over 15 papers in this field.

Dr Guy Boggs
Chief Executive Officer, CRC TiME

Guy has extensive experience providing leadership in innovation and actively working at the interface of industry and research. Guy has led the delivery of large Australian Government funded programs driving knowledge development and industry practice change. An experienced research leader, Guy holds a PhD completed on post mine landform design and has an extensive publication record authoring over 50 books, book chapters and journal articles on spatial science and natural resource management.
Guy is committed to enabling a new vision for mine closure and positive post mine transitions through effective stakeholder engagement, research planning and innovative solutions.

Professor Richard Herrington
Head of Earth Sciences, Natural History Museum, UK

Richard currently leads a major new research theme at the Natural History Museum (NHM), London focused on resourcing a green economy. This theme brings together both earth and life scientists to look at holistic, nature-inspired solutions to the challenges of delivering the resources needed for the net-zero challenge, whilst remaining nature positive. With a long career in research focused on discovery and recovery of metals and minerals, he has an extensive publication record and is regularly called upon to consult for industry. He recently stepped down as Head of Earth Sciences at the NHM and is currently a councillor for the Society of Economic Geologists, is a member of the UK Government’s Critical Minerals Expert Committee and an advisor to the UK’s newly launched Critical Minerals Intelligence Centre.

Mining is creating vast quantities of waste and is inherently damaging to land. These two issues have been among the most intractable in resolving sustainable mine closure. Here we propose a new ambitious concept for future mining practice, where land use and material waste are recognised as part of a mine’s assets not its legacy. The challenge is to build a closed-circuit mining system where all excavated materials are exploited as a resource. These uses may be quite disconnected from the primary mined ore where other industrial, agriculture or urban uses may be found, along with more conventional uses for encapsulation of toxic wastes and the reconstructed and sustainable post-mining landscape. This demands more detailed knowledge of the mineralised system from the earliest exploration stage, outlining the nature of the entire orebody and enclosing rock mass that will allow a more complete planning of mineral recovery and handling of discarded material, accommodating any plans for future secondary recovery operations. This knowledge also directly informs the planned reconstruction and remediation strategy. Postmining landscapes need to have reconstructed ecosystem services that are designed to be net nature positive.

Professor Longbin Huang
Professor of Ecological Engineering, The University of Queensland

Longbin is a specialist in ecological engineering of mine wastes for resilient and sustainable rehabilitation. He leads an industry-partnered research program on Ecological Engineering of Mine Wastes, delivering sustainable technologies for rehabilitating tailings landscapes. Over the last decade, Longbin has developed the technological platform for eco-engineering of technosols from Cu-tailings, Fe-ore tailings, coal spoils and rejects, and bauxite residues for offsetting natural soil needs in rehabilitation. His achievement is highlighted by the recently patented technology to eco-engineer bauxite residues into fertile soil with industry-scale feasibility, in partnership with Rio Tinto and QAL.
