Beyond Design-and-Walk-Away: Why Heap Leach Governance is Catching Up with Tailings

Heather Thomson, Breese Burnley - June 23, 2026

This article examines how global heap leach failures are driving a shift toward tailings-style governance, with greater emphasis on independent oversight, lifecycle planning, and closure from the outset.

On the Probability of Failure of Tailings Dams by Flow Liquefaction Considering Combined Triggers

Lisandro Roldan, Mauro Giuliano Sottile, Alejo Sfriso, Florencia Spinazzola - June 15, 2026

This paper presents a probabilistic framework that integrates the 2nd Generation of Eurocode 7 geotechnical design principles with advanced numerical modeling to assess the vulnerability of TSFs to flow liquefaction under combined actions.

Monitoring Adjustments After Unexpected Rain-Induced Deformation Accelerations in a TSF with a Rockfill Buttress

Manuel Cervantes,Alejandro Calvo,Ignacio García,Fabian Arquin - May 29, 2026

This paper presents a case study of an embankment TSF that underwent stabilization through the construction of a downstream rockfill buttress and improvements monitoring systems.

Bayesian Characterization of a Tailings Dam Following Eurocode 7 Principles

Lisandro Roldan, Alejo Sfriso, Florencia Spinazzola, Manuela Boyero, Nicolás Ibañez, Tomás Iriarte - May 28, 2026

A Bayesian procedure is presented for estimating undrained shear strength in tailings dams by integrating CPT data, lab tests and expert judgment, quantifying uncertainty and deriving Eurocode‑7–consistent characteristic strengths, thereby improving design and stability.

A Practical Framework for Benchmarking Failure Rates of Tailings Storage Facilities

Holly Williams, Adam Leik, Daryl Hockley - May 26, 2026

The study applies a hierarchical Bayesian approach to derive benchmark annual failure rates by construction method and operational status, highlighting differences across upstream, downstream, single-raise, and dry-stack TSFs.
