Update as of April 16, 2026 MDT

Newmont is providing an update following assessment work at the Cadia operation, after the magnitude 4.5MLa earthquake recorded earlier this week in the New South Wales Central West.

The safety and wellbeing of our workforce remain our priority. All safety protocols were activated immediately at the time of the event. Underground personnel moved to designated safe areas, and all workers safely returned to the surface over the following hours in accordance with our protocols. There were no injuries.

Inspections indicate that while damage is present to certain underground areas, it is not significant. Processing operations have been steadily ramped up and are returning to normal throughput. All surface infrastructure, including tailings facilities and dams, were inspected immediately after the earthquake and no damage has been identified at this time. Based on current assessments, near-term production is not expected to be impacted. Assessment work underground continues to determine the full recovery timeline and if there will be a longer-term impact to production.
