Dear Ryan, please receive this open letter to the organizer of the tailings dam round robin exercise. It explains our position on the round robin exercise you have promoted. As you know we enthusiastically adhered to your round robin proposal although we found a bit odd that such an exercise would be led by a consultant, thus not an impartial entity. Very quickly we started asking for more data, as the knowledge base seemed rather generic. We were not surprised…

TMW2022 discussion and video presentation covers some important points and coveys our gratitude to the friendly colleagues that helped us overcome a significant work overload. Indeed, for the first time since 2013, we could not make it to the conference to present in person the results of our R&D. We were particularly sorry for this, as the reviewer wrote: The authors present a discussion on how to optimize actions needed to address risk mitigation to ALARP for a large TSF…

In order to develop a Tailings risk assessment methods comparison we will start by: reviewing a number of existing alternatives to ORE2_Tailings™. This leads to justify the need for the ORE2_Tailings™ approach, discussing what we call the Blackbox objection, which actually applies to all the alternatives and finally the ORE2_Tailings™ procedure, algorithm and results. Alternatives to ORE2_Tailings™ We have grouped possible alternatives into four families discussed below. FMEA FMEA is not a quantitative risk assessment even if it uses indices…

Readers and conference delegates asked the following Questions on ALARP studies at Tailings 2022 and when they read a case study on ALARP optimization. National regulation compliance Are the results of an ALARP analysis consistent with national regulations and design requirements? When we perform an ALARP analysis we consider local regulations. These will drive some a priori mitigative selections by the engineer of record. These bear on the nature and aim of mitigation stages for the ALARP analysis. For instance,…

Zero to 300 in thirty is not the performance of a new sensational sport car. And we are talking about thirty years, not seconds! Actually, zero to 300 in thirty years is the cumulative experience Riskope and its founders have dealing with tailings dams risk assessments all over the world. You should not understand it as an “average” evaluation either, as the evolution has been trending towards exponential. Let’s discover together what we are talking about. Zero to 300 in…

TCFD and TNFD for mining: concepts, examples and caveats, is the paper we presented at #CIMBC22 Mineral Economics and Finance. Photograph provided by: Adolfo Tribst Corrêa We asked the audience if they were familiar with the: Task Force on Climate Related Financial Disclosure (Task Force on Climate-Related Financial Disclosures | TCFD) (fsb-tcfd.org) and Task Force in Nature-related Financial Disclosure (TNFD – Taskforce on Nature-related Financial Disclosures). Only a couple hands rose. Significant points of our discussion on TCFD and TNFD for…

FUV vs RIDM friends or foes at CIMBC22 sounds like a riddle, right? But it is not! Please, note FUV was actually never written as an acronym. Actually FUV stands for firmitas, utilitas, et venustas in Latin language. Today we freely translate the terms into English as reliability, serviceability and beauty, straying a tad away from the original meaning. However, Henry Wotton, a seventeenth century translator, coined “firmness, commodity, and delight” as essential components of all successful architectural design. Wotton remained faithful…
