ORE2 tailings deployment steps

ORE2 Tailings deployment steps: 5.1 Failure definition We designed ORE2_Tailings™  to support RIDM for tailings dams portfolios reliability enhancements. One achieves reliability by reducing failure likelihood to a certain level, and risks are tolerable. Thus it is necessary to clearly state what one considers the success of a structure within the portfolio. Indeed, unless we clearly define success, failure remains an ambiguous term.   ORE2_Tailings™ considers a dam successful if it: stands as built and does not break allowing for…

General ORE2 tailings workflow

ORE2_Tailings™ is a quantitative risk assessment platform. Riskope designed it specifically for tailings systems (active and inactive). When we deploy ORE2_Tailings™ to a portfolio of dams, possibly over multiple properties, it allows for tactical and strategic planning. Our practice has shown that ORE2_Tailings™ and the general ORE2 tailings workflow, delivers results similar to those of common practice quantitative approaches (Event trees, Failure trees, Bowties). Furthermore ORE2_Tailings™  enables answering specific questions linked to the causality of potential failures, optimization of cost…

Sustainability, ethics and risks

Sustainability, ethics and risks results from a discussion we read on LinkedIN. The discussion arose after our friend Giuseppe di Capua cited SUSTAINABLE MINING – WHAT EXACTLY DOES IT MEAN? . The author of that paper is David Ovadia, for the @IAPG blog ( ). The core of the discussion These days,  mining projects oftentimes tout their ‘sustainability’. The term reverberates from sources like the UN’s sustainable development goals. David Ovadia wonders if the term sustainable  can be used in mining.…

Tailings dam mitigation risk informed decision making

Tailings dam mitigation risk informed decision making closes the discussion we presented in prior blogposts. We now focus on one dam and show how ORE2_Tailings™ supports rational and sensible risk mitigation decision-making as requested by GISTM. The dam case The dam we selected for this example is inactive and is parallel to a valley bottom. An unprotected creek runs at its toe and the bed is considered to be sufficient for the 1/500 return. Beyond that flood, there will be…

Tactical and strategic planning for dam portfolio using ORE2_Tailings

Tactical and strategic planning for dam portfolio using ORE2_Tailings is the third of a series of blogposts explaining how to use ORE2_Tailings™ results. Indeed it follows: Dam portfolio ORE2_Tailings support for decision makers and ORE2_Tailings supports ICMM global industry standard on tailings management conformance. We use the same figures we have developed in those prior discussions. Summary of the portfolio ORE2_Tailings™ results With respect to probability of failure The portfolio of ten dams is made of two “bad apple” dams…

Risk tolerance for tactical and strategic planning

We discuss risk tolerance for tactical and strategic planning using an excerpt from a case study in our forthcoming book. The title is Convergent Leadership – Divergent Exposures and the case study is in Chapter 16. In the book we include three complete case studies with different level of information and requirement. Setting of the case study covering risk tolerance for tactical and strategic planning Kryptonite corp. has three plants shipping bulk material through a wharf called Terminal reached by railroad…

Tolerable risk thresholds

Tolerable risk thresholds, aka risk tolerance are always project and owner-specific. They indicate the level of risk which has been deemed acceptable for a specific project or operation. Furthermore, tolerable risk thresholds and appetite for risk is quite different for various key stakeholders, for instance: Mine owner, Regulatory Bodies, Adjacent Communities, etc.   So how can one manage the sometimes divergent tolerable risk thresholds between stakeholders? Additionally, a topic that comes regularly in the mining world is diverging risk tolerance among…

Convergent Leadership Divergent Exposures

The title of our new book is Convergent Leadership Divergent Exposures. The manuscript was delivered to our publisher on March 1st 2021 and should be published by July 29th 2021. How will Convergent Leadership Divergent Exposures benefit you? Today’s corporate, industrial and government decision makers must address risks and hazards on a scale never before encountered. As a matter of fact, policy makers and managers face complex business-as-usual hazards, black swans and Acts of God that can lead to devastating…
