Tikou Belem

Université du Québec en Abitibi-Témiscamingue (UQAT)


Professor of Geomechanics and GeoEnvironmental Engineering

Research Institute of Mining and Environmental (RIME)

Université du Québec en Abitibi-Témiscamingue (UQAT)


Dr. Tikou Belem is a Professor of Geomechanics and GeoEnvironmental Engineering at the Research Institute of Mining and Environmental (RIME) of the Université du Québec en Abitibi-Témiscamingue (UQAT). He started working on mine fills since 1998 and accumulate over 24 years of experience in industry-related research on solid mine wastes management, including cementitious materials through underground mine backfilling. Thanks to the proximity of UQAT to the numerous mines in Abitibi-Témiscamingue, Prof. Belem has developed a strong expertise on mining with backfill. He has also served as a specialist external reviewer for some consulting engineering firms.

Dr. Belem has contributed to the realization of numerous technical service contracts on mine backfills with almost all the mining companies operating in Quebec and many others internationally (Finland, Mali, Mexico, Sweden). Prof. Belem has also attracted the trust of many engineering consulting firms in Canada and abroad to benefit from his strong expertise on mine backfills.

Concerned with the need to always find practical, reliable, and affordable solutions for the mining operations with backfill, Prof. Belem has largely contributed to the development of physical models simulating the hydro-mechanical properties of backfilled mine stopes at the laboratory scale. Dr. Belem's work on the backfilling sequencing was awarded the Best paper award at the 23rd World Mining Congress, organized by the Canadian Institute of Mining, Metallurgy and Petroleum (CIM).

More recently, Dr. Belem carried out a major research project on the evaluation of the performance of superabsorbent polymers in the management of mine tailings in terms of dehumidification, cemented paste backfill preparation, retention of heavy metals and metalloids, and creation of a barrier layer to water and oxygen.

Since 2003, Prof. Belem has implemented a course on mine backfills whose presentation notes are highly valued by rock mechanics and ground control engineers in the mining industry. This course is given to undergraduate students in mining engineering and to graduate students in mineral engineering at UQAT and Polytechnique Montréal.

Manager Research & Development

Yure Mladinic is Manager Research & Development within Rio Tinto Copper based in Brisbane, Australia. He graduated with an engineering degree from Universidad de Santiago de Chile and obtained an MBA from Vlerick Business School in Belgium.

In his current role he has supported the shaping of the Rio Tinto Copper technology pipeline by accelerating key programmes with a focus on growth and strategic priorities. This has included establishing a partnership with BHP to jointly accelerate the development of tailings dewatering technology.

Yure has over 15 years of experience in the mining industry including JV management and governance, partnerships, technology development, capital projects, mine operations and technical. He is passionate about teamwork, partnering internally and externally, and designing and implementing innovative solutions.

Clara Balasko


Head of Planning and Technical

Clara Balasko is the Head of Planning and Technical for BHP Legacy Assets. The Legacy Assets team manages 23 sites in various stages of closure across Canada and the United States of America. Clara is a civil engineer with 20 years of experience spanning geotechnical, environmental, and closure design, execution, and construction management focusing on lifecycle management of tailings storage facilities.

She has a Bachelor’s in Geology from Texas A&M University and a Master’s in Geological Engineering from the University of Nevada, Reno. She started with BHP 4 years ago as a Responsible Tailings Facility Engineer for BHP’s 18 tailings storage facilities in the US and held the Geotechnical Manager position prior to her current role. Before joining BHP, she also worked as a consultant on projects in the Americas, Australia, and Asia.

Projects she worked on include 1) design and field engineering for closure of plant facilities, tailings impoundments, waste rock dumps, and a heap leach facility as part of the BHP San Manuel Mine Closure, 2) design of the tailings and waste rock storage facility in Papua New Guinea that required the design of a two large (greater than 200 m) earthen dams in an area of high seismicity, and 3) operational support for a tailings storage facility at a Copper Mine in eastern Nevada.
