Bellevue Gold tasks GR Engineering with process plant build

Bellevue Gold Limited has awarded GR Engineering Services Limited engineering, procurement and construction (EPC) work related to the 1 Mt/y gold processing plant and associated infrastructure for its namesake project in Western Australia.

GR Engineering will immediately commence design engineering services and ordering of long lead and design critical path equipment including the ball mill, crushing equipment, screens, agitators, leach and tailings thickeners, prior to entering into a formal EPC contract.

Geoff Jones, Managing Director, said: “GR Engineering is pleased to be working with the Bellevue team on this exciting gold project. This project further enhances GR Engineering’s reputation as the leading gold EPC contractor in Australia.”

Bellevue Managing Director, Steve Parsons, said GR Engineering knew the project well from its work during the study phase.

“Commencing manufacturing of these long-lead critical components of our 1 Mt/y processing plant de-risks the construction schedule and puts Bellevue on the pathway to first gold in the second half of 2023.

“The appetite among leading contractors and suppliers to be involved with our project speaks volumes about its strong future.”

Bellevue is forecasting production of 200,000 oz/y during years one to five at an all-in sustaining cost of A$922/oz ($653/oz) at its operation.

Artemis awards Blackwater gold EPC contract to Sedgman Canada

Artemis Gold Inc says it has made an award for the engineering, procurement, construction and commissioning (EPC) scope of works for the processing plant and associated infrastructure at its Blackwater project in British Columbia, Canada, to Sedgman Canada Limited, a CIMIC Group company.

The award amount of approximately C$312 million ($243 million) is consistent with the prescribed budget for the process plant and selected infrastructure scope of works in the 2021 feasibility study.

Sedgman Canada Limited is a wholly owned subsidiary company of Sedgman Pty Limited, a CIMIC Group company. CIMIC Group (ASX:CIM) is an engineering-led construction, mining, services and public private partnerships leader working across the lifecycle of assets, infrastructure and resources projects.

The EPC contract is expected to be executed by June 30, 2022, with the contract supported by performance security including bank letters of credit, which will underwrite the financial performance and obligations of the contractor under the contract.

While the parties finalise the definitive EPC contract, in order to maintain the project schedule, an interim services agreement has been agreed which could cover procurement and pricing of long lead equipment and optimisation through refined scope changes, among other aspects.

The project schedule supporting the award to Sedgman includes the following assumptions:

  • Construction mobilisation and major works preparations commence in Fall 2022 with process plant bulk earthworks scheduled to be completed prior to the start of major works;
  • Commissioning activities of the process facility to commence in Q1 (March quarter) 2024; and
  • First gold pour expected in the first half of 2024.

The final EPC contract terms will provide for potential cost adjustments of certain components of construction representing approximately less than 15% of the total contract amount, including the potential for cost adjustments from further quantity definition, Artemis said. Standard adjustments, including currency exchange rates for certain equipment purchases also apply, and further optimisation of the processing plant with final engineering will occur.

Artemis is also considering awarding additional construction packages under an EPC agreement type structure to further enhance the risk management of the total capital expenditure for Blackwater, it said.

When combined with the EPC for the Power Transmission Line announced on August 18, 2021, the percentage of the estimated total capital expenditure for Blackwater under EPC is on track to target circa-60% of the initial Stage 1 development capital of C$645 million in a lump sum EPC type arrangement by the September quarter of 2022.

Stage 1 development should lead to the building of a 6-9 Mt/y operation (6 Mt/y in years 1-4 and 9 Mt/y in year 5) able to produce around 312,000 oz/y of gold.

Steven Dean, Chairman and CEO, said: “The award of the EPC job for the process plant at Blackwater is another significant milestone for Artemis, reflecting a competitive process involving multiple bidders. We are very pleased to be working with a world-class engineering firm in Sedgman. In partnership, we will work to finalise the design and engineering of the Blackwater project in advance of a start of major development activities. Blackwater remains on track for a start of major construction activities following receipt of Mines Act and other permits in Fall 2022 with a first gold pour in H1 2024.”

Austin to supply NRW Civil & Mining with 16 ULTIMA truck bodies

Austin Engineering says it has secured a A$7 million ($5 million) agreement to supply 16 locally-made truck bodies to Australia-based mining contractor NRW Civil & Mining, a unit of NRW Holdings.

Austin and NRW marked the award with a steel plate cutting ceremony for the first of the ULTIMA truck bodies to be manufactured on site at Austin’s Kewdale facility, which is co-located with the company’s new corporate headquarters in Western Australia.

In addition to representatives from Austin, the ceremony was attended by NRW CEO, Jules Pemberton, and other NRW representatives, along with Chamber of Minerals and Energy Western Australia Chief Executive Officer, Paul Everingham.

NRW is an arm of Australian diversified contract services provider NRW Holdings, which services the resources and infrastructure sectors in Australia. Its services include civil construction, bulk earthworks, road and rail construction and concrete installation, contract mining and drill and blast services.

NRW has ordered 16 ULTIMA high performance truck bodies and two 6060 Face Shovel buckets from Austin, which will be manufactured at Austin’s Kewdale site over the coming months.

Austin’s Kewdale facility is one of two of the company’s major manufacturing sites in the Asia Pacific region, the other being in Indonesia. The company is investing A$6.5 million to implement advanced manufacturing processes and capabilities at these sites, including increased automation and the use of custom jigs, fixtures, workstations and a standardised manufacturing approach to building product.

The Kewdale facility will receive the first manufacturing upgrade, which will benefit customers, such as NRW, and enhance the company’s supply of Western Australian-made dump truck bodies and other hauling and loading products, Austin says.

Austin Chief Executive Officer and Managing Director, David Singleton, said: “We are extremely pleased to sign this contract with NRW, one of Australia’s leading mining contractors. The contract adds to a solid order book for Austin. Our recent strategic review demonstrated the opportunity to upgrade our manufacturing facilities to increase production efficiency while enhancing product quality and operator safety. We are the leading designer of truck bodies in the world, and intend to be the most efficient too.”

GR Engineering wins Mt Ida EPC contract from Aurenne Alt Resources

GR Engineering Services says it has executed an engineering, procurement and construction (EPC) contract with Aurenne Alt Resources Pty Ltd in relation to the Mt Ida gold project in Western Australia.

Mt Ida, which Aurenne inherited with the acquisition of Alt Resources last year, is in the eastern goldfields of the state.

GR Engineering said the contract sum is approximately A$73 million ($54 million) and work is expected to start immediately.

Geoff Jones, Managing Director of GR Engineering, said: “GR Engineering is pleased to have been awarded the EPC contract by Aurenne and we look forward to working collaboratively with the Aurenne team. This project further reinforces GR Engineering’s reputation as the leading gold EPC contractor in Australia.”

Alt Resources previously outlined the need for a 750,000 t/y processing facility at Mt Ida in a 2020 feasibility study prior to being acquired by Aurenne.

Berco on the latest innovations in mining undercarriage solutions

Berco, part of the thyssenkrupp Forged Technologies Business Unit, is continuing to innovate within the undercarriage component market segment, with Francesco Grenzi, Executive Director of R&D, talking up some of the company’s most recent solutions for demanding applications like mining.

With over 100 years of experience and expertise in the industry, Berco says it manufactures and supplies undercarriage components to the world’s leading heavy machinery OEMs and to the aftermarket.

“Universally renowned for the very high quality of its products, Berco’s reputation is further bolstered by its dedication to providing tailor-made and innovative solutions for applications that operate in both unique and extreme conditions,” Grenzi says.

A recent challenge for Berco has been that of extending the number of hours of its mining excavator application.

“Because of the work efficiency of the most advanced mining excavators, as well as the extremely different working modes used in the open-pit mines, the goal of achieving 20,000 maintenance-free hours was indeed a difficult one,” Grenzi said.

The traveling rate of an undercarriage is also something that can significantly vary between applications. When blasting is being carried out, for example, the heavy machinery will naturally be evacuated from the area before detonation. In situations such as this, the use of carburised bushings is recommended to reduce the speed of wear.

For applications that do not travel frequently, however, undercarriage parts are still often subjected to wear. Continuous hammering of the front shovel, for example, may not lead to quick wear of the bushings, but can cause other side effects such as cracks on bushings.

Berco’s solution in this case was to use both quenched and tempered, and induction hardening and tempering bushings, as well as a quenched and tempered steel with boron to increase hardenability. These specially produced bushings deliver even more added value when fitted on reinforced chains, Grenzi said.

This solution, which is designed for heavy application such as for track chains used on 200-400 t machines, provides high resistance to wear as well as outstanding resistance to impact, according to Grenzi. Being capable of achieving up to 20,000 hours of use in the field, it ultimately reduces ownership and undercarriage costs. Since November 2020, they have been fitted as original equipment on two of the machines the manufacturer has built to perform in Russia’s most extreme environments.

While heavy machinery manufacturers look to Berco for tailor-made solutions, the company goes one step further by placing a large emphasis on R&D to anticipate solutions that are ever-more innovative, Grenzi says. An example of this is the use of ‘rotoforged’ steel in the production of rollers for very demanding mining applications.

This pioneering process will bring significant benefits to machines that have a huge load transfer in their working times, such as mining excavators that weigh above 200 t. For applications of this size and even heavier (350-400 t), the rollers are under pressure as they take all of the inertia of the vehicle. This means that the rollers need to be made of “perfect steel”, which is why the ‘rotoforging’ process is ideal, according to Grenzi.

Steel that has undergone this heat treatment process acquires a high microstructure and compactness, to such an extent it is able to achieve toughness values double those of conventional steel, he said. Continuous casting steel is usually rolled. Rolled steel that undergoes the new ‘rotoforging’ process has its microstructure transformed down to the core, resulting in a much stronger and tougher structure.

“For this reason, rollers made from ‘rotoforged’ steel are suitable for machines which must operate in the most demanding environments around the globe,” Grenzi said. “They offer a very high level of reliability of between 15,000-20,000 hours. This innovation is now ready to enter production.”

Nordic Mining enlists firms for EPC at Engebø rutile and garnet project

Nordic Mining, through its wholly owned subsidiary Nordic Rutile AS, has entered into letters of intent with Sunnfjord Industripartner AS, Åsen & Øvrelid AS, Nordic Bulk AS, and Normatic AS as partners for the engineering, procurement and construction (EPC) of the Engebø rutile and garnet project in Norway.

The LOIs are a formalisation of the EPCs deliverables toward the update of the Engebø definitive feasibility study (UDFS), and in line with the optimised contracting and execution strategy developed to ensure the successful construction of the project, the company said.

Sunnfjord Industripartner is a company founded to compete on larger contracts for industry and communication development projects, Åsen & Øvrelid is one of the largest civil and building contractor on the west coast of Norway, Nordic Bulk designs, manufactures and installs plants for processing and handling of bulk material within the mining and quarrying industry, and Normatic is a significant provider of control systems, instrumentation, electrical cabinets, electrical systems and SCADA systems.

The LOIs comprise lump sum EPC contracts covering around 70% of the total plant and mine capital expenditure of $203.4 million. The parties plan to formalise the final EPC contracts by early in the September quarter.

In preparation for construction, Nordic Mining says it will, together with its selected project management consultant and the selected EPC partners, immediately start pre-construction work related to setting up the project management organisational structures and systems and selected detailed engineering activities.

A January 2020 feasibility study on Engebø envisaged an optimised mining plan and scheduling to support an initial 42-year mine life and a 1.5 Mt/y run of mine operation. This would see 15 years of open-pit mining and high-grade processing, and stockpiling of medium/low-grade ore, 19 years underground production, eight years of production with no mining costs based on stockpiled ore, and further project life extension possibilities based on the inferred resources.

Project Manager, Kenneth Nakken Angedal, said: “We are pleased to sign the agreements with the EPCs supporting the project in the update of the definitive feasibility study and, by that, moving the Engebø rutile and garnet project towards execution. Our focus has been to partner with companies on what they are best at, and that have the experience to support in construction and operations, which will support creating value for the region in many years going forward.”

Civmec captures another contract at BMA’s Hay Point coal terminal

Civmec Ltd has been awarded a contract to manufacture wharf girders and associated structures for the development of port infrastructure at the Hay Point loading port, owned by BHP Mitsubishi Alliance (BMA), in central Queensland, Australia.

The BMA agreement will see Civmec make over 13,500 t of these girders and associated structures, with procurement and shop detailing activities commencing immediately and fabrication starting in the June quarter.

Loadout onto Heavy Lift Vessels is scheduled to start in early 2022, with the last vessel planned for load out in the June quarter of 2022. The project will employ over 350 people during fabrication and assembly at the company’s Henderson facility, in Western Australia.

BMA has already engaged Civmec to fabricate, modularise and commission the 1,800 t SL2A ship loader using pre-contract capital ahead of a large infrastructure replacement project at Hay Point.

Civmec’s Chief Executive Officer, Patrick Tallon, said: “The award for the Hay Point port infrastructure work is the second significant package of works that we have been trusted to deliver for this port upgrade. We look forward to delivering a high-quality product to McConnell Dowell to allow them to have a seamless installation at the site location and welcome the opportunity to work alongside all stakeholders on this project.”

These works are part of the Shiploader 2 and Berth 2 Replacement (SABR) project at Hay Point, which McConnell Dowell is heading up. The SABR project scope encompasses replacement of one of the three berths and shiploaders at the terminal.

SRG Global bolsters South32 relationship with more Worsley Alumina work

SRG Global says it has secured a long-term circa-A$100 million ($72 million) contract with South32’s Worsley Alumina operations to provide specialist refractory services, including gunning and casting and installation of refractory products and anchors.
