GR Engineering Services has received a Letter of Intent from K92 Mining Ltd, a subsidiary of TSX-listed K92 Mining Inc, for the engineering, procurement and construction (EPC) works associated with a 1.2 Mt/y process plant at the Kainantu gold mine in Papua New Guinea.

K92 Mining owns and operates Kainantu, a producing gold mine that has existing infrastructure at site. The EPC works are being performed as part of K92 Mining’s Stage 3 Expansion plans.

K92 Mining has successfully executed multiple expansions at the Kainantu Gold Mine, after restarting operations at the site in 2016.

In addition to the award of the contract, all process plant long-lead item contracts have already been awarded on a fixed price (excluding freight), to CITIC HIC Australia Pty Ltd for the SAG and ball mills, Jord International Pty Ltd for the filter press and Metso for the tank flotation cells, flash flotation cells and high-rate thickeners, K92 says.

The contract sum for the EPC contract is $81 million, with GR Engineering having commenced engineering works on an agreed scope and cost basis. The contract is expected to be finalised by the end of August 2023.

Tony Patrizi, Managing Director, said: “GR Engineering is a leading gold EPC contractor and has previous experience on PNG projects through our Brisbane office. We are looking forward to assisting K92 Mining achieve their expansion plans and to delivering a safe outcome for the project.”

K92 says commissioning of the 1.2 Mt/y Stage 3 Expansion process plant is targeting the end of the March quarter of 2025.

Jord International addresses pressing issues for BMA Caval Ridge

Jord International has recently taken up a challenge from BHP to come up with a safer solution to filter press maintenance at the Caval Ridge metallurgical coal mine, in Queensland, Australia, as part of the New South Wales-based company’s expanding remit to unlock new technologies for the wider mining industry.

The plant and systems designer, developer and service provider was awarded the project, part of BHP’s Supplier Innovation Program challenge, earlier this year. It has seen Jord design and construct the first concept prototype in tandem with the maintenance team at the mine.

The prototype comprised a belt cartridge installer within a self-contained steel frame that holds a new belt and removes the old, damaged belt. The first commercial belt installer is expected to be in use by July, according to BMA.

Craig Samuel, Jord’s Mechanical Engineer for Aftermarket and Reliability, said the filters the company worked with at BMA Caval Ridge are 3 m wide x 5 m long, with the product path through the filter around 14 m long. While the solution was designed for Caval Ridge specifically, he said it could have applications on any site or with any commodity using filter presses.

“The idea came from the understanding of how the filter belts are installed, and a cartridge-style installer just made sense considering Caval Ridge has a readily available crane to move the cartridge around,” Samuel told IM. “The mechanics of the installer required some out-of-the-box ideas to develop a continuously variable speed ratio between the new belt roll and the old belt roll.”

Samuel said he expected the belt change time to be cut in half with this new solution.

Jord has already applied for another BHP Supplier Innovation Program challenge that could leverage a dust management and cleaning innovation, but the company has also been investing in research and development to commercialise new minerals beneficiation technologies for more efficient and effective liberation of ore, according to Kevin Barber, Jord’s General Manager of Resources.

“Our goal is to unlock new technologies that provide step-change improvements to current processes in the industry,” he said of these new technologies. “It’s about using less energy, using less water and removing some of the environmental challenges with particular focus on tailings. We’re finding alternative ways of dealing with problematic ores and resources.”

BHP Mitsubishi Alliance tasks Jord International with filter press maintenance challenge

Jord International has been tasked to develop a safer solution to filter press maintenance at BHP Mitsubishi Alliance’s Caval Ridge metallurgical coal mine, in Queensland, Australia, as part of BHP’s Supplier Innovation Program challenge, launched in partnership with Austmine in 2020.

The program follows a model that has operated successfully in BHP’s Minerals Americas business for the last decade, the miner says.

In January, Jord signed a Collaborative Agreement with BHP – the first under this new challenge – to design and construct the first prototype of this idea, working hand-in-hand with the maintenance team at BMA’s Caval Ridge metallurgical coal mine, near Moranbah.

Jord is proposing a safer way to perform maintenance on filter presses that removes moisture from coal rejects at the wash plant. It comprises a belt cartridge installer within a self-contained steel frame that holds a new belt and removes the old damaged belt.

The first belt installer is expected to be in use by July, according to BMA, with the pilot to run for six months. If successful, the new approach will be implemented permanently at Caval Ridge, and potentially at other BMA sites using filter presses to remove moisture from coal rejects, BMA added.

Jord’s Mechanical Engineer for Aftermarket and Reliability, Craig Samuel, developed the concept and says it eliminates the need for operators to be in physical contact with the filter press.

“Creating a safer environment is the pinnacle of an engineer’s ethos and it’s incorporated in everything we design,” Samuel said. “We know from experience that efficiency and reliability are critical to mining operations, so I’m proud that this idea will make a traditionally time-consuming task much faster and I’m looking forward to working closely with the Caval Ridge team.”

When developing the award submission, Samuel consulted with Jord’s field service team to ensure the concept was practical and rigorous enough to meet the demanding operating conditions.

Jord’s General Manager of Resources, Kevin Barber, said he is proud of his team for having the drive and innovative thinking required to solve this long-standing industry challenge.

“We would like to thank BHP for their recognition and for the opportunity to participate in genuinely collaborative discussions about real challenges faced in the industry,” he said. “At Jord, we live by the motto ‘ideas engineered’, which means we encourage our people to share new ideas. We often invest in research and development initiatives with a goal to commercialising new products.

“We look to add value in all our projects, whether it’s increasing safety, reducing risk, producing a higher-grade product, increasing plant capacity, minimising environmental impacts, or conclusively proving new industrial processes.”

BHP says its Procurement Innovation & Community team is currently developing another six Supply Innovation Program challenges across Minerals Australia, with the goal of announcing more pilot contracts in coming months.
