Mastermyne’s Aquila coking coal contract extended by Anglo

Anglo American has extended the stay of Mastermyne Group at its Aquila coking coal project in Queensland, Australia, with the ASX-listed contractor set to continue development of the underground mine for at least the next 12 months.

Mastermyne has been engaged since August 2019 to undertake roadway development in the mains and gate roads, and all outbye related services for the establishment of the new longwall operation at Aquila.

The contract variation will extend the current contract to March 2022 and includes the operation of an additional roadway development unit.

Mastermyne currently employs 178 full-time personnel under the contract, with a further increase of around 60 full-time personnel required for the operation of the additional roadway development unit. Up to half of the personnel for this third development unit at Aquila mine will be relocated from Anglo’s Moranbah North coal mine (currently suspended), following the completion of planned activities. Mobilisation of the additional workforce at Aquila will be completed by March 2021.

The contractor says it continues to supply development equipment from its fleet, including a continuous miner and ancillary development equipment for the project.

Total revenue generated from the variation and extension to the mining contract is expected to be approximately A$60 million ($47 million).

Mastermyne CEO, Tony Caruso, said “We have been working to deliver major underground infrastructure and roadways safely and efficiently, and we look forward to continuing our work with Anglo American to deliver their new longwall project, producing premium high-quality hard coking coal.”

Anglo’s 70%-owned Aquila project will extend the life of its existing Capcoal underground operations by six years and continue to use the associated infrastructure at the Capcoal complex as its nearby Grasstree mine approaches end of life, Anglo says. The project is scheduled for first longwall production of coking coal in early 2022.

Water treatment plant starts up at Anglo American’s Aquila met coal project

Anglo American’s Metallurgical Coal business says it is now operating the first of two state-of-the art reverse osmosis (RO) water treatment plants at its Aquila project in the Bowen Basin, Queensland.

The aim of the RO plants is to reduce the use of fresh water in its mining operations.

Chief Executive Officer of Anglo American’s Metallurgical Coal business, Tyler Mitchelson, said the A$5 million ($3.9 million) water treatment system was currently treating two megalitres of mine affected water (MAW) a day and supporting construction of the Aquila Mine, near Middlemount in central Queensland.

“A key target in Anglo American’s global Sustainable Mining Plan is to reduce our reliance on fresh water by 50% by 2030 across our mine sites, and I’m pleased to say Aquila is currently sourcing recycled water during construction of the mine,” Mitchelson said.

“A planned second RO plant will to be used to recycle a further 2.4 megalitres of MAW – once Aquila becomes operational in early 2022, more than doubling capacity and helping to reduce the reliance on water from local sources during times of drought.

“Aquila will be one of the world’s most technologically advanced underground mines and will showcase our innovation-led approach to sustainable mining. The project is currently supporting 500 jobs.”

Aquila, owned 70% by Anglo and 30% by Mitsui & Co Ltd, will extend the life of Anglo’s existing Capcoal underground operations by six years and continue to use the associated infrastructure at the Capcoal complex as its nearby Grasstree Mine approaches end of life, Anglo says. The mine will also continue to adopt Anglo American’s FutureSmart Mining™ program, which applies innovative thinking and technological advances to address mining’s major operational and sustainability challenges, the company said. One of the initiatives the company is working on as part of this is remote operation of the longwall; a process the company has trialled at some of its other Bowen Basin coal mines.

Aquila’s Project Director, Tony Willmott, said the A$240 million Aquila Mine was committed to awarding contracts locally.

“Our Aquila project is progressing well, with support from its Queensland-based workforce and contracting partners. More than 90% of our Aquila contracts have been awarded to Queensland-based suppliers,” Willmott said. “Aquila’s integrated network of pipes and pumps is securing the distribution of high-quality water which is necessary in metallurgical coal mining for equipment cooling and coal cutting operations.”
