Zero to 300 in thirty

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

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) ( 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

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…

World-wide ORE2_Tailings quantitative risk assessment experience

Riskope’s world-wide ORE2_Tailings quantitative risk assessment experience can be summarized in one single graph we will show below. ORE2_Tailings™ (©Riskope, 2014-*) is a subset of ORE (Optimum Risk Estimates) which is a “universal” platform for quantitative risk assessments, ERM we deploy for: mining, i.e. tailings, open pits, transportation, forestry and finally suppliers. We have deployed ORE for hundreds of operations worldwide. Today we will focus on tailings storage facilities. Sample portfolio for ORE2_Tailings™ performance summary  We selected a sample portfolio…

The five laws of stupidity and risk management

The five laws of stupidity and risk management are deeply interconnected. As a matter of fact, stupidity is often the root cause of many accidents, in any industry or human endeavor. Haven’t we all heard phrases like: “… it was a stupid accident”, “it was a stupid mistake…”? Like usual, we will ensure that the glossary is crystal clear before we discuss the subject. And like usual, you will see that a clear glossary is absolutely vital. The classic definition…

ORE2 tailings tactical and strategic

As stated earlier ORE2_Tailings™ allows to define in a clear, transparent, and reproducible way which risks are tolerable or intolerable. Among the intolerable risks ORE2_Tailings™ allows to define which risks are tactical and which ones are strategic. We discussed tactical and strategic planning for dam portfolio using ORE2_Tailings™  in  In our reports we show that risks of the considered portfolio belong to a three families as follows: tolerable, meaning they are below the risk tolerance of the client. These…

ORE2 tailings RIDM

We split this Chapter in two sections: section 10.1 discusses what actions one can take to enhance the knowledge base. These are obvious “simple” procedural mitigations. Thye lead to better understanding of the risks and/or to mitigate them. Section 10.2 shows how one can deploy ORE2_Tailings™ during the mitigation design process. That is in order to support decision-making. The goal is to define rational and sustainable risk mitigation programs. This process has to occur in parallel with the design by…

first steps ORE2 tailings workflow

First steps ORE2 tailings workflow: 2 – ARCHIVAL DOCUMENT SEARCH METHODOLOGY The archival documents delivered by the client to Riskope should cover the TSFs and their dams including: geotechnical studies; geological studies; design reports; geotechnical analyses reports; inspections; correspondence; incidents descriptions; dam break analyses; FIA and GISTM consequences evaluations; emergency plans; and finally monitoring (equipment and measurements as applicable). During the deployment we deliver an analysis of the archival gaps, i.e. a list of documents that are apparently missing or…
