The management of tailings and the structural integrity of our tailings storage facilities are critical to community safety and environmental protection.
Our tailing storage facility (TSF) are engineered structures designed and constructed to hold mineral waste (tailings) from our processing facilities. We design, construct and manage in compliance with all Philippine regulations and, where applicable, any additional requirements consistent with our management standards and framework.
Our TSF Management Statement of Position commits our company to the safe management of TSF throughout the tailing’s facility life cycle (including closure) by avoiding and mitigating potential harm to the environment, employees and affected peoples and communities. This was updated to align with the requirements of the Global Industry Standard on Tailings Management.
Downstream construction
In Didipio Mine, a downstream TSF is constructed with a single embankment (wall) formed with waste rock to create engineered embankments that are progressively raised to provide additional space for tailings storage.
Paste backfill
Once processing is complete up to 40% of the mine tailings can be diverted to a paste plant where it is mixed with cement and used as backfill material for underground mine voids, which reduces the volume of tailings delivered to the TSF.
