ORE2_Tailings supports ICMM global industry standard on tailings management conformance (GISTM). ORE2_Tailings™ is a risk assessment platform specifically designed for tailings systems created by Riskope. We recently published the notes we took while reading ICMM guidance and conformance protocols. In that text we stated that ORE2_Tailings™ anticipated the requirements of ICMM GISTM. Indeed, the threads of our publications, which culminated with Tailings Dam Management for the Twenty-First Century shows that evolution. Today we bring to your attention an example…

Most tables of risk comparisons in the literature contain a mix of risks characterized by different levels of uncertainty. In addition, most risk comparisons in those tables offer only single number risk estimates, with no range or error term. For risks such as driving, where fatalities can be counted on large samples, the number is likely to be reliable, at least in some countries. However, even if the risk comparison data are carefully and accurately reported, they can be misleading.…

Cadia tailings facility failure expert review and risk considerations allow us to discuss InSAR application and low seismicity considerations for pre-failure risk assessment. The Cadia Ridgeway Mine failure was already the object of a preliminary discussion in the immediate aftermath of the unfortunate event. These themes are very important and are present in our forthcoming book Tailings Dam Management for the Twenty-First Century What Mining Companies Need to Know and Do to Thrive in Our Complex World By Franco Oboni and…

Riskope’s new book Tailings Dam Management for the Twenty-First Century is in print. This book is based on over thirty years of world-wide consulting experience, relentless methodological research and development, prior books, courses, seminars delivered to corporate key stakeholders, public and governmental agencies, public hearings, expert witnessing in civil and criminal courts, and over fifty technical papers. Its purpose is to identify and describe risk assessment approaches and risk management practices mining must implement to develop a positive path forward. That is…

Tailings dams quantitative risk assessment has to rely on proper evaluation of consequences and probabilities. The goal is to be able to economically and swiftly prioritize a portfolio of dams. That is in order to develop risk informed decision making for mitigation as also discussed in a recent blogpost. ORE2_Tailings app to evaluate probabilities ORE2_Tailings app is primarily addressing the needs of owners or regulators of dam portfolios. A dam portfolio may cover several extractive centers, several mining companies with…

Today we discuss how ORE2-Tailings allow benchmark of tailings dams probability of failure. The considered mine for this case history has a portfolio of 15 dams. The figure below shows in the vertical axis the annual Probability of failure (pf) results under the form of yellow vertical bars. The extreme of the bars represent the minimum and maximum estimates of the probability of failure for each dam. Hence, the length of the bars measures the uncertainty on the evaluation of…
