Sales from Gloucester's operations increased 17% at the end of June to 2.1 million tonnes, jumping from 1.8Mt the previous year.

Gloucester said its new acquisitions, which had significantly improved the long-term growth of the company, were a significant achievement of the year.

Gloucester acquired a nearly 50% interest in the Middlemount mine in Queensland’s Bowen Basin and also purchased Donaldson Coal Holdings in July this year.

Major developments at Gloucester’s Duralie extension project and the Middlemount project were undertaken, including the commencement of reviewing its Donaldson operations.

While total coal production was down 5%, Gloucester’s coking coal and thermal coal sales rose with demand for the company’s high ash thermal product remaining high.

Gloucester said it had high expectations for the coming year, with continued drilling at its Monash tenement and a planned ramp up in production at Duralie to 3Mtpa by 2014.

Gloucester will have an updated reserves and resource statement on its projects in the first half of the 2012 financial year.
