Rio Tinto says it will manage the Ranger Rehabilitation Project in Australia’s Northern Territory on behalf of Energy Resources of Australia Ltd (ERA), under a new Management Services Agreement (MSA) signed today.

The MSA will build on ERA’s existing rehabilitation work with Rio Tinto’s technical expertise in designing, scoping and executing closure projects. Transition to Rio Tinto management of the project will start immediately and is expected to take about three months.

The agreement follows an approach to Rio Tinto from ERA’s Independent Board Committee (IBC) to submit a proposal to provide services and advice to progress the project. Rio Tinto owns 86.3% of ERA’s shares.

Under the MSA, Rio Tinto and ERA aim to complete the Ranger Rehabilitation Project in the safest and most efficient way, and to a standard that will establish an environment similar to the adjacent Kakadu National Park and that is consistent with the wishes of the Traditional Owners of the land, the Mirarr people, it said.

Rio Tinto Chief Executive, Australia, Kellie Parker, said: “With the signing of this agreement, we are pleased to be able to directly provide more closure and project delivery experience and know-how to this critical task. So far, ERA has made progress in key areas, including water, tailings treatment and management and pit rehabilitation.

“We are aligned with ERA in wanting to build on this work using Rio Tinto’s expertise in closure projects and our commitment to strong stakeholder relationships. We look forward to working in partnership with the Mirarr Traditional Owners and other stakeholders to complete the project.”

ERA CEO, Brad Welsh, said: “The ERA team has worked incredibly hard and made good progress rehabilitating Ranger. However, as the project moves into a new phase it will benefit from Rio Tinto’s global expertise in mine closure.

“We look forward to working with and supporting Rio Tinto on the safe and efficient delivery of this important project.”

Rio Tinto plans to build on the expertise and relationships existing within the ERA team to finalise required studies and execute the necessary rehabilitation activities, it said. Management of ERA matters outside the Ranger Rehabilitation Project, including corporate matters, financial affairs, assets and governance will remain the responsibility of ERA.

TNG Ltd has appointed a subsidiary of engineering and construction company, Clough, to work with TNG’s project development team and the SMS Group on its flagship Mount Peake vanadium-titanium-iron project in the Northern Territory of Australia.

TNG announced in September that it had decided to progress development of the project with a fully-integrated mining and processing operation within its existing mining leases. As part of this strategy, it was considered by the TNG team important to have a suitable Australian-based engineering group on board.

Following a tender process, Clough Projects Australia Pty Ltd was selected to work with TNG’s team to initially develop an optimised plant layout for the integration of the TIVAN® processing facility (TPF) and beneficiation plant at the mine site, on the basis of the deliverables prepared under the front-end engineering and design (FEED) study completed by SMS group.

Clough, TNG says, will work with SMS and TNG’s team given the severe restrictions on travel between Europe and Australia due to the COVID-19 pandemic that have impacted SMS’ ability to deliver a team in Australia.

TNG previously engaged Clough to assess the definitive feasibility study for the project and this new contract expands on this early work to progress the overall mine development, it says.

The optimised layout will be unconstrained compared with the size and shape requirements at the former Darwin site. This offers the potential to capitalise on improving constructability, operability and maintenance for the project, as well as further cost optimisations from integrated infrastructure, the company says.

The integrated plants will be positioned within the company’s existing Mining Lease 29855, which has a size of 1,460 ha. This area is capable of hosting a fully-integrated operation encompassing mining activities and waste storage, the beneficiation plant, the TPF and non-process infrastructure, according to TNG.

TNG’s Managing Director & CEO, Paul Burton, said: “From a strategic and logistical perspective given the continued global COVID-19-related travel restrictions, it is an advantage to have a locally-based engineering group working on this phase of the Mount Peake project with TNG and SMS.

“We expect the integrated plant layout will pave the way for further optimisation work that will tie back into the recently completed FEED study. These work programs are already underway. We look forward to working closely with Clough and our other engineering partners to rapidly advance the Mount Peake project.”

Located 235 km north of Alice Springs, Mount Peake is expected to be a long-life project producing a suite of high-quality, high-purity strategic products for global markets including vanadium pentoxide, titanium dioxide pigment and iron ore fines. The project, which is expected to be a top-10 global producer, has received Major Project Status from the Northern Territory and Federal Governments.

Core Lithium has awarded Primero Group with the engineering, procurement and construction (EPC) contract for the Finniss lithium process plant in the Northern Territory of Australia.

Primero’s award status has been updated from the initial preferred status awarded in 2019 and continues the long-standing relationship in the development of the project with the Core Lithium team and follows on from the successful delivery of Core’s definitive feasibility study and subsequent study updates, NRW Holdings, the parent company of Primero, says.

The project will commence immediately and is fully funded with site works planned to commence in March 2022 with commissioning of the facility due to commence in October 2022, according to NRW.

Primero’s work on the Finniss dense media separation (DMS) plant will entail project management; engineering and detailed design; equipment and materials procurement; DMS plant construction; quality assurance and construction verification, and ore commissioning on receipt of first ore, according to Core.

Primero Managing Director, Cameron Henry, says: “The Primero brand is synonymous with the processing and operation of battery metals and future energy and the Core Lithium project is another example of the quality of our processing knowledge in these industries. The working relationship with the Core team has been a four-year journey and we look forward to delivering on this contract and continuing the relationship with Core.”

NRW CEO, Jules Pemberton, added: “The NRW Holdings business continues to diversify its business streams into the future metals and energy space with another great award to the Primero Group team in the electric vehicle space with Core Lithium.”

The August definitive feasibility study on Finniss outlined a Stage 1 mine life of eight years with average production of 173,000 t/y at 5.8% Li2O.

Hastings Deering, Cat and Rio Tinto carry out Australia’s first 777 D to E conversion

In what it says is a first for the Australia market, Hastings Deering has successfully completed the conversion of 777D haul trucks into 777E models for Rio Tinto’s Gove bauxite operations in the Northern Territory.

The 777D to E conversion process includes an engine upgrade from an older Cat 3508 to a C32 Tier 2 engine, a transmission upgrade to electronic clutch control, torque converter upgrade and an upgraded cab with the latest electronics and safety aspects.

Nearing the end of mine life, Gove was looking at innovative ways to reduce its environmental impact, extend fleet life and optimise return on investment, Hastings Deering said.

Brendan Coleing, Superintendent, Mining Maintenance, said that the Gove operation has focused heavily on building safe and reliable machinery to meet the targeted life of its assets and has been working to reduce environmental emissions.

“With a 24/7 operation, we need to plan and strategically think about our assets, their maintenance and lifecycle,” he said.

“All machines have availability targets. Ultimately, we want to keep them in the field as long as possible. The 777D to E Conversion project was a way we could continue the journey to do that, with the added benefit of providing improved technology to our operational teams.”

He concluded: “We’re excited that Gove operations was the first Australian mine to undertake this project, and only the second in the world. With a significant reduction in our carbon footprint, fuel consumption and maintenance costs, and an improved operator experience, really, we were challenged with: why wouldn’t we?”

With the first of the 777 trucks now back on site, the Rio Tinto team has seen a 5-6% fuel reduction, proving that effective planning for this fleet conversion has improved economy on site, Hastings Deering said.

With Cat equipment built to perform over multiple lifetimes, the Cat Certified Rebuild (CCR) was the most efficient way to help get the most economic value out of the asset investment, according to Hastings Deering.

A CCR is a full machine rebuild that provides a like-new machine, inclusive of all Cat updates, to help achieve a full machine life supported by the Caterpillar warranty.

In early 2020, the Hastings Deering team worked with Rio Tinto on an alternative solution for engine replacement in its D11R fleet that, it says, reduced costs, fuel use and emissions while extending lifespans. This incorporated replacing the 3508 engines with the newer C32 engines.

“Recent success with repowering our D11 fleet with C32 engines has helped our mining operations move more bauxite due to increased power in the machine,” Coleing said. “This, in turn, allowed us to plan for the 777D to E conversions to take place in the workshop to complete the CCRs.”

Chris Polkinghorne, Mining Support Rep at Hastings Deering, said that the 777D to E conversion was brought about through collaboration with Caterpillar, Rio Tinto Gove and Hastings Deering.

“As a team we worked through what the benefits of this conversion would be, what was required, the planning phase and then how to execute the project in as little time as possible,” he said. “The 777D to E conversion redefines performance adding all the advancements of the 777E truck model.

“For the operator, improved ergonomics provide enhanced comfort, safety, and visibility, to maximise productivity and reduce fatigue.”
