Open pit production commenced in 2004 with underground production commencing in 2005. Initial capital costs were $39 million. Current reserves and resources are sufficient to provide a mine life through to around 2018. However, in early 2014 Panoramic Resources announced the discovery of Savannah North, and later in August 2015 reported the Interim Savannah North Mineral Resource estimate. The company expects that the discovery will have a significant impact on mine life, adding more than eight years according to a 2016 scoping study.
