Escarpment mine


The Escarpment mine is part of the Buller Project, which covers 10,000 hectares of exploration and mining permits on the Buller coal field on the Denniston Plateau.

The Escarpment mine on the Denniston Plateau near Westport is home to some of the world’s most valuable hard coking coal used for steel making.

Mining commenced at Escarpment in late 2014 developing the long term water control structures and forming the infrastructure pads. Coal was extracted as part of the early construction phase and was blended into the local cement plant. With the closure of the plant in early 2016, a decision was made to place the mine into care and maintenance in May 2016. This was the result of detailed planning and feasibility work, which demonstrated that the mine required certain levels of production to be profitable.

We’ll continue to review various operating options for Escarpment in parallel with building relationships with customers – both here and offshore. Through the acquisition of the nearby Stockton mine, we’ll continue developing routes to market and prospective customers so we’re ready to meet this demand when the time is right. The Stockton purchase also allows us to investigate options for access to infrastructure and synergies to markets for the Escarpment mine.

Until then, environmental compliance at the site will continue until mining starts again. This includes monitoring acid mine drainage, water discharges and weed control.
