Kestrel mine

From Global Energy Monitor

The Kestrel mine is an underground mine — previously known as Gordonstone mine — located 40 km north east of Emerald in the Bowen Basin in central Queensland. In 2019, the mine produced 6.76 million tonnes of coking coal.[1]

After being washed and prepared for sale, the coal is railed 300km southeast to the Port of Gladstone where it is shipped to international customers. The mine uses a longwall method.[1]

Mining began at Kestrel in 1992, when the mine was known as Gordonstone. At the time, the coal project was led by a joint venture between ARCO, an American oil company, Mitsui, a Japanese coal trader, and an Australian company known as MLC. ARCO had 80% of the ownership. By 1996-97, annual production capacity was around 4.4 mtpa.[4]

In 1999, Rio Tinto bought the majority stake in Kestrel mine.[4] Rio Tinto operated the mine until 2018, when its share was bought by EMR Capital Group (41.6%) and PT Adaro Energy.[5] Rio Tinto also oversaw a $2 billion expansion that was begun in 2008 and completed in 2013. According to Mining Technology, the expansion increased the mine’s annual production capacity to 6 million tonnes per year and extended ist life until 2032.[6] However, in 2017, the mine produced just 4.25 million tonnes of hard coking coal.[7]

Under EMR Capital Group’s and PT Adaro Energy’s ownership, annual production increased to 6.76 million tonnes per year in 2019, achieving a record run-of-mine (ROM) coal mining volume in underground mining.[1]

Joint venture

PT Adaro Energy and EMR Capital Ltd (EMR) acquired Rio Tinto’s 80% interest in the Kestrel Coal Mine (Kestrel) in August 2018 to jointly manage and operate Kestrel’s mine. Upon completion of the deal, ownership stakes in Kestrel consisted of Kestrel Coal Resources Pty Ltd (80%) and Mitsui Coal Australia (20%). Kestrel Coal Resources Pty Ltd is a joint venture company formed by EMR (52%) and AE (48%).[1]
