To maximise the potential of all
our resources



At our HVO South and HVO North mines near the Upper Hunter town of Singleton, we mine up to 42 million tonnes of high quality thermal and semi-soft metallurgical coal a year to help meet the world’s energy needs.

Our mines support up to 1,500 jobs. Spending more than $500 million a year on goods and services with more than 700 suppliers creates thousands of flow on jobs. Through community grants and charity support, taxes and mining royalties, HVO also supports local and state infrastructure and projects that benefit communities. In 2022, HVO’s direct economic contribution was $1.5 billion. 

Our long history, extensive mining experience and investment in equipment, technology and people makes HVO a safe, sustainable and reliable mining operation. We monitor and manage operational impacts to treat the surrounding environment with respect and care for future generations. We work with local communities and the agricultural sector to support local farming, community projects and jobs. Our goal is to always do things better.

We offer rewarding and diverse career opportunities to talented people who think sharp, dig in and care about customers, the environment and communities.

HVO is proposing to continue its operations to 2050 to meet short to medium term demand for its coal. By essentially mining existing seams deeper, there’ll be little change to the scale of mining and no increase to already approved annual production rates.

Our mine has been operating since 1949. We have a long and proud history of being part of the local community. HVO is now jointly owned by Yancoal (51%) and Glencore (49%) and independently managed through a joint venture partnership.
