Tailings

We have committed to aligning all tailings facilities with The Global Industry Standard on Tailings Management (GISTM).

Our Tailings, Mine Waste and Water Storage Facilities Group Standard sets our minimum performance expectations for the management of tailings ensuring a focus on the safety and integrity of Tailings Storage Facilities (TSFs) to protect people and the environment. Each Asset’s mine waste and tailings facilities are unique and our TSFs are designed to account for site-specific factors including local physiography, climate, land rehabilitation considerations, geological, seismic and hydrologic conditions and proximity to people and/or infrastructure.

We continue to work towards our voluntary commitment to align with GISTM. In 2021, we committed to achieving alignment with the GISTM within five years. At the time, our operations were limited to a single mine in Australia. We are now a global mining company with operations across three continents, each with distinct regulatory environments, opportunities and challenges.

While we remain committed to aligning with the GISTM, we will not achieve full alignment by 2026. This delay is primarily related to the closure of the MATSA – Depósito de Pasta Seca (DPS) facility and the pending final regulatory approval to commence construction of the new MATSA – Instalación de Gestión de Tailings (IGT) facility. We continue to prioritise the safe and responsible management of tailings. In FY26, we will develop a program of work to support alignment with the GISTM by FY28.
