Bulga Underground

Bulga Underground was a longwall mining operation with a proud history as one of Australia’s highest producing underground mines.

While the operation ceased in May 2018, Glencore Coal is retaining mining approvals to support any future mining options.


Open cut operations are continuing at the site, 15 kilometres south-west of Singleton near Broke and Bulga villages in the Upper Hunter Valley in New South Wales.


Bulga Coal is a joint venture between Saxonvale Coal Pty Ltd (87.5%) and Nippon Steel Australia Pty Ltd (12.5%). Saxonvale Coal Pty Ltd is 100% owned by Oakbridge Pty Limited.

In turn, Oakbridge is an incorporated joint venture between Enex Oakbridge Pty Limited (83%), ENEOS Australia Pty Limited (15.2%) and JFE Shoji Corporation (1.8%). Enex Oakbridge Pty Limited is 100% owned by Glencore.


Mining started at Bulga Underground at South Bulga in 1992, moving to Beltana in 2001 and finally to the Blakefield South operation in 2008, finishing in May 2018.

The legacy left by a world class underground operation remains. In December 2014, Bulga Open Cut received approval to continue operations until 2035.


Rehabilitation projects at Bulga Underground are showing excellent results.

Glencore Coal remains committed to preserving the long-term health of the areas affected by our operations.
