Tomingley Gold Operations

Gold mining and production

Tomingley Gold Operations: Plant Layout

Open cut and underground gold mine

Tomingley Gold Operations lies approximately 50km southwest of Dubbo in the Central West region of NSW and is part of the Tomingley Gold Project.

The original project was approved to end-2025, based on four gold deposits: Caloma One, Caloma Two, Wyoming One and Wyoming Three. We began with open cut mining and our first gold pour in early 2014, then commenced underground mining in 2019. These resources have together yielded more than 500,000 ounces of gold.

Extending operations until at least 2032

The Tomingley Gold Extension Project will extend gold mining operations to include the San Antonio and Roswell resources immediately south of the existing mine. 

The project involves development of an underground mine at Roswell and one large open cut pit. The life of mine plan shows production of at least another 750,000 ounces, and a potential annual production rate of 100,000 ounces in 2025.

Safety

Safety is entrenched in every decision and action at Tomingley. We value safe production and celebrate the successes of meeting and exceeding targets and budget safely.

Our philosophy is to ‘entertain doubt’, an underlying principle of the Social Psychology of Risk (SPoR) methodology followed onsite. SPoR seeks to understand how people really tackle risk by accounting for human fallibility, mortality and subjectivity.

Caring for the environment

  • Our activities are carefully designed to use water responsibly and efficiently. Tomingley currently draws 50-70% of our 1000ML entitlement.
  • We continue to explore renewable energy solutions to support power requirements.
  • Through careful design, construction and maintenance, we preserve the structural integrity and performance of our waste storage facilities.
  • We re-purpose and recycle many consumables to recapture key materials and minimise our impact on landfill.
  • We undertake progressive rehabilitation of our disturbances to restore stable and productive ecosystems.
  • We’ve partnered with the Toongi Pastoral Company to improve the overall land and soil capability of approximately 1450ha of agricultural land near Tomingley.

Careers

Tomingley offers rewarding career opportunities for university graduates, people qualified through the vocational education and training (VET) system, apprentices in some trades and operators with experience in heavy machinery. We value employees from a diverse range of backgrounds and are committed to equal-opportunity recruitment.

We are a “residential” operation, meaning all employees return to their own homes at the end of each shift. The site is near the major regional centres of Dubbo and Narromine. Our employees also benefit from the breadth of experience and collaboration that comes from working at a smaller operation.
