Update as of January 6, 2026

Newmont is providing an update on the recent bushfire that began in mid-December and affected the area surrounding our Boddington operations in Western Australia.

Following favorable weather conditions and the tireless efforts of emergency responders, the fire was contained by Sunday, December 28, but remains active and will require continual monitoring and management in the weeks ahead. We are grateful to report that all Newmont employees and contractors have remained safe, with no serious injuries reported in the community.

Operations were suspended on December 24, and once the emergency situation stabilized, site inspections on December 28 confirmed that critical infrastructure-including the pit, processing plant, tailings facility, and key administrative buildings-remained secure and undamaged. Bushfire preparation protocols were in place, ensuring all major infrastructure was protected during this extreme fire event. However, we have identified damage to a portion of the site's water supply infrastructure.

Production for 2025 was not impacted by the fires, given we were able to maintain production for the majority of December. Mining and processing operations have resumed, but the processing facility will run at reduced rates (50-60%) until the main water supply infrastructure is restored. It is estimated that this infrastructure will be fully restored through February, with a forecast impact of ~60 Koz Au expected in the first quarter of 2026.

Newmont continues to provide critical support to regional emergency services, including equipment and maintenance for firefighting equipment. We extend our sincere thanks to the Department of Fire and Emergency Services, the Shire of Boddington, the more than 200 emergency responders, and our workforce for their exceptional efforts in safeguarding the community and our operations from this extreme event.
