Phil Newman, Head of Tailings Innovation, Anglo American

The future of tailings management is being driven by a higher degree of scrutiny and oversight than ever before, and for good reason. The need to design large geotechnical landforms that will stand up to the test of nature for the long term are not the type of geotechnical conditions that most geotechnical engineers are used to. The safe design of tailings storage facilities is not only critical to the mining industries success; factors including sustainable water stewardship and planning for closure are at the forefront of tailings management.

These focus areas are driving change and innovation in the tailings space, but innovation in mining is hard, particularly at the back end of the process where the scale of waste management dwarfs most industries. For the last 6 years, Anglo American has been developing the proof of concept for an innovative approach to tailings management that aims to address the three key focus areas of safety, water stewardship, and closure—without the cost of existing technologies such as filtered tailings.

Hydraulic dewatered stacking (HDS) looks to utilise a specific by-product from the mining waste stream and repurpose it within the tailings facility design to accelerate consolidation, increase the rate and desaturation, and reduce the overall degree of entrainment of water in the tailings mass. The presentation will provide an oversight of the approach and the proof of concept to date, from laboratory to a 150,000-ton large-scale field trial. We will detail some of the challenges of innovating at scale, the results from the trials so far, and where we can go from here. We look forward to seeing you all there.

Mark has over 25 years of experience in the field of geotechnical engineering applying his trade to civil infrastructure projects in sectors including highways, railways, airports, ports, and power. Mark began his career in geotechnical engineering consultancy with Scott Wilson before moving to Ghana in 2010 to work for Knight Piesold. Since 2010, Mark has been practicing in the field of tailings management and has worked on mining projects across West Africa, the Nordics, and Eastern Europe. Mark joined Golder (now WSP) in 2017, and recently joined KCB in their York office.

James has managed the design and construction of Tailings storage facilities in northern Europe and West Africa. He has 8 years’ experience in the tailings field and 11 in geotechnics. He is deputy EOR on one facility, whilst working closely with EOR’s on other TSF’s and has spent prolonged periods supervising construction works on site, managing relationships with the client and contractor. His project experience ranges from project management through to undertaking detailed modelling and design.

Phil has 35 years mining experience covering paste technology and innovative tailings solutions. A founding member of Golder PasteTec in 1996, he designed and built numerous paste backfill plants around the world and pioneered the use of geotubes for tailings management in the early 2000’s. Since joining Anglo American in 2015, Phil has focused on innovation across the value chain with a focus on tailings innovation since 2023.

This presentation explores Japan’s Hishikari gold deposit to challenge the traditional view of low-sulphidation epithermal systems.

Using new zircon dating and trace element data, the talk demonstrates how direct magmatic contributions—specifically shifts in magma temperature and oxidation—play a crucial role in gold mineralisation and metal fertility.

We face two major environmental crises: the destructive extraction of natural sand and the massive buildup of hazardous mine waste (tailings) driven by the energy transition.

“Ore-sand” offers a single solution to both.

By deliberately processing mineral waste into usable, sustainable sand, the industry can supply global sand demands while preventing hazardous tailings at the source.

Join Women in Mining UK and MinSouth for a special joint hybrid fireside chat discussion between Dr Sarah Gordon, Board Member at Women in Mining UK; Founder, Satarla; WIM100 2026 and Dr Frances Wall, Professor of Applied Mineralogy, Camborne School of Mines, University of Exeter; WIM100 2026.

Sue Struthers:

I am a mining geologist/environmental engineer with 33 years of experience in the mining industry. Following a BSc from London University and an MSc in Mining Geology from Camborne School of Mines in 1984, I spent ten years as a geologist, firstly with ZCCM on the Zambian Copperbelt and then with Mount Isa Mines in Queensland. Much of my work with MIM involved investigation of all aspects of leaching, as a metallurgical process and an environmental issue, including in-situ leaching tests for copper, SE-EW and tailings retreatment. A strong interest in the impacts of mining and a move to Melbourne, led to a PhD in environmental engineering from RMIT, focussing on the feasibility of recycling mine tailings. Subsequently I have worked as an independent mining environmental consultant through Skapa Mining Services, involved in a wide range of projects, from geochemical investigations and characterisation; AMD prediction-, management- and troubleshooting; rock dump and tailings storage, management and rehabilitation; ESIA planning-, management- and reviews; NI43-101 reviews; feasibility studies; developing and implementing mine environmental and social management systems and plans; environmental auditing; and Gap Analyses and compliance work for Equator Principles and IFC performance standards; to health and safety, and social aspects of operations.

I am a Chartered Environmentalist and a fellow of IoM3.

Stuart MacGowan: I was educated at St. Olaves’ Grammar School in Kent before completing a 4-year geology degree at the Royal School of Mines. Graduating in 2015, I then studied for an MSc in Mining Geology at the Camborne School of Mines, which I completed at the beginning of September 2016. My dissertation pertains to exploration in the Copperbelt. I am a keen mineralogist and petrologist who prefers the field to the desk as a place to work. In any spare time I play hockey and go clay pigeon shooting whenever possible.

Throughout my time as a student I have held roles on behalf of the RSM and Society of Economic Geologists (SEG). During my final year I was President of the SEG Chapter at the RSM, which planned and ran a three-week field trip to Eastern Europe, examining porphyry systems and their associated epithermal regimes.

I have constantly been at the forefront of increasing student involvement with the SEG, MinSouth and, in a wider sense, the Geological Society. In my opinion, the events run by these bodies, particularly MinSouth, are a hugely underused resource for students. The monthly sundowners have reasonable attendance, though I have yet to see students at any of the talks or events which have taught me so much about the industry. My opinion of the university system at the moment is that is biased towards box-ticking and exam-passing rather than producing graduates with an understanding of how the world generally works. I feel there is a lost opportunity here and I would like to once again increase student involvement with MinSouth.

Simon Kocher: Having always had a strong interest in minerals and mining it appeared natural to pursue a career in geology, which led to a degree in economic geology from the University of Tuebingen. After a period of working as near mine exploration geologist on greenschist metamorphic VMS deposits in Northern Sweden I took on a PhD position with Imperial College and the Natural History Museum London. Currently I am researching the distribution of molybdenum in the Bingham Canyon porphyry deposit, Utah to gain a deeper understanding of the behaviour of Mo in porphyry systems. This project is carried out in cooperation with Rio Tinto. Since 2012 I am a member of the MinSouth council and in 2013 I joined the applied earth sciences board of IOM3.

Paul Griffin: I graduated from Cardiff as a Mining Engineer in 1977. After a period of postgraduate research I joined Dowty, the mining equipment manufacturers, where I worked throughout the world’s underground coal industry for some 13 years. In this period of my life I was fortunate to work in Australia, Canada, South Africa, Eastern Europe and India.

In 1993 I joined the Australian mining software developer, Surpac where I was European Manager and then Group Finance Director. In the time with Surpac I established offices in South Africa, Chile and India. I was awarded my MBA through the Open University in 1999.

After a period of merger and acquisition I became VP Sales for Gemcom in 2006 before eventually leaving to run my own freelance activities in 2008. I also returned to study (yet again!) and was awarded a degree in Law in 2010.

Outside my professional activities I also am an advisor with the Citizens Advice Bureau.

Patrick Cox: Following studies in Geology and Engineering I have worked internationally on projects covering infrastructure, natural resources and the extractive industries including the UK, Hong Kong and Australia including practice and research to develop advisory studies guiding policy. I am a Fellow and Chartered Engineer with IOM3 and a Fellow and Chartered Geologist through the Geological Society with more than 30 years of experience but a continued passion and interest in the profession and business of multi-disciplinary geosciences, including geology, hydrogeology and engineering geology all critical areas within society and under exposed, which am wanting to make a continued contribution to change. Strategic ground risk management and opportunity is where I like to work technically. I am a STEM Ambassador and advocate for diversity, equity and equality. I am especially keen on using STEM-based thinking and foundations in smart solutions using technology and resources efficiently with benefits to sustainability evidenced in authoring key guidance on the use of geosystems in civil engineering. I am presently Chair of Think Deep UK which has similar goals to Minsouth in seeking to raise awareness of the importance of the resources beneath us
