Callide Mine produced 8.8 million tonnes of coal last year and has a resource base of more than 1 billion tonnes.

Anglo American currently has debt of $10.9bn and the mining company is divesting assets from steel plants to phosphates as part of a plan to dispose of non-core assets and focus on metallurgical coal and high margin export thermal coal businesses.

In July the company announced to sell its interests in five undeveloped steel and thermal coal assets in Australia for $500m and sell its stakes in the Peace River metallurgical coal assets in Canada.
