Newmont Cadia is one of Australia’s largest gold and copper mining operations, located approximately 25 kilometres from Orange in Central West New South Wales and 250 kilometres west of Sydney.
The site comprises the operational Cadia East underground mine, one of the world’s largest gold and copper deposits, which commenced commercial production in 2013 using large-scale panel caving methods. The Ridgeway mine remains in care and maintenance, while the Cadia Hill Pit supports tailings storage.
The site is currently advancing underground development for Panel Cave 1-2, following the completion of PC2-3 draw points. With a 35-year reserve life and continued investment in infrastructure, tailings capacity, and environmental performance, Cadia remains a long-life, world-class operation.
- Cadia is one of the world’s largest producing gold and copper mines, owned 100 percent by Newmont, following the acquisition of Newcrest Mining Limited in November 2023.
- While Cadia is currently approved to continue operations until 2031, mineral resources have been identified for production up to 2048–2050.
- To continue supporting regional investment, jobs and the national renewable energy transition targets, Newmont is seeking approval from the NSW Government and Federal Government to extend Cadia’s mining operations beyond 2031. This is known as the Cadia Continued Operations Project (CCOP).
- Cadia produces gold doré bars from a gravity circuit and gold-rich copper concentrates from a flotation circuit. The concentrates are piped to a dewatering plant at nearby Blayney and sent by rail to Port Kembla in New South Wales for export.
- The Molybdenum Plant was commissioned during the March 2022 quarter and delivers an additional revenue stream in the form of molybdenum concentrate which is a by-product credit to All-In Sustaining Cost per ounce.
- First drawbell fired at PC1-2; cave establishment for PC2-3 on track to be completed in late 2026.
- Advancing tailings improvements and investments to support cave development and extend mine life.

Social Performance
The history of the Cadia Valley begins with the Wiradjuri people, whom Newmont acknowledges as the traditional owners of the land. To this day, Cadia works proudly in partnership with the Orange Local Aboriginal Land Council. As short-term custodians of the land in which Cadia operates, the workforce respects the values of historic assets and places on the site and the role of traditional owners and custodians of the land.
Cadia is committed to engaging openly and honestly with the communities of Panuara, Errowanbang, Four Mile Creek, Waldegrave, Forest Reefs, Spring Terrace, Burnt Yards, Blayney and the wider Cadia district. Through its ongoing engagement activities, Cadia aims to deliver long-term benefits to the local community that leaves a lasting economic and social legacy.
A dedicated social performance team is based onsite to maintain open dialogue with stakeholders and ensure that Cadia operations contribute positively to local development.
Through its successful Workforce Engagement Program, Cadia provides opportunities for the workforce to participate in community and environmental programs to give back to the local community.
Cadia recognises that strong environmental performance is essential to operational success and community trust. Environmental risks and impacts are managed through a comprehensive Environmental Management Strategy (EMS), which ensures that activities are planned, monitored, and continuously improved in line with regulatory approvals and community expectations.
The EMS is supported by detailed management plans and monitoring programs developed in consultation with government agencies and local stakeholders. Key focus areas include air quality, noise, vibration, surface and groundwater, biodiversity, rehabilitation, and heritage. Results are regularly reported and made publicly available.
Rehabilitation is guided by a dedicated strategy aligned with commitments in the Cadia East Environmental Assessment and Project Approval. Ongoing trials inform best practices for land restoration, ensuring that closure planning is integrated into current operations.
