MLG Oz extends service ties with Evolution Mining at Mungari operations

MLG Oz Ltd is set to extend its relationship with Evolution Mining Limited after being selected as its preferred service provider to service its Mungari operation, located in the Goldfields region of Western Australia.

The award of the new contract for the provision of haulage and integrated site services issued under Evolution’s wholly owned subsidiary, Evolution Mining (Mungari) Pty Limited, is for an initial contract term of two years, with a provision for a further one-year extension at Evolution’s discretion. The contract, MLG says, leverages its large Kalgoorlie-based resourcing pool and off-road haulage assets.

The Mungari district, now under the single ownership of Evolution, has a significant mineral endowment with a large portfolio of resources delivering long term feed options to the company’s centrally located Mungari processing infrastructure. Mungari produced 115,829 oz of gold at an average all-in sustaining cost of A$1,453/oz ($1,003/oz) in the financial year ending June 30, 2021.

MLG founder and Managing Director, Murray Leahy, said: “We commenced our first contract with Evolution less than a year ago and we are delighted to be awarded this opportunity to enhance our long-term relationship. This contract marks a significant milestone in our pursuit to provide superior integrated services to our customers.”

The new contract will see annualised revenue with Evolution effectively double to some A$15-$18 million, MLG said. The company’s scope of works builds on the recent integration of the Kundana operations into Evolution’s Mungari portfolio, with MLG engaged to service the combined sites bulk haulage and road maintenance requirements under a single service provider arrangement.

MACA receives contract extension from Regis Resources at Duketon North

MACA has announced the extension of its mining services contract with Regis Resources Ltd at the Duketon North Operations (DNO) in Western Australia, having provided mining services at the project since 2010.

The service offering includes a dedicated workforce of 258 personnel delivering drill & blast, load & haul, plant maintenance and technical services across the Regis open pits in the area.

This extension is expected to generate up to A$50 million ($36 million) per year in revenue for MACA and will utilise the contract miner’s existing fleet on site. DNO continues to run alongside the Duketon South Operations (DSO).

Both parties have signalled their intention to explore conversion of both the DSO and DNO contracts into an amalgamated partnership-style life of mine alliance arrangement post June 2023, MACA said. The asset produced 356,000 oz of gold in the 2021 financial year.

MACA’s work in hand position including this contract is in excess of A$2.6 billion at April 2022.

MACA CEO, Mike Sutton, said: “MACA is delighted to continue its long-standing relationship with Regis at the Duketon North Operation. Our team has a long-standing relationship with Regis and MACA is proud to be an ongoing part of this operation. This project will be undertaken utilising existing fleet and contributes to MACA’s secured mining work in hand in the Goldfields region, ensuring future work continues to consist of a balanced portfolio of commodities.”

Zenith Energy to roll out 5B Maverick solar system across Australian mine sites

Renewable energy penetration is set to increase on major mine sites in the Goldfields and Pilbara regions of Australia, after Zenith Energy and 5B signed a deployment agreement that could see the 5B Maverick™ system rolled out.

Zenith, one of Australia’s leading independent power producers, and 5B, a clean energy technology provider, signed an Ecosystem Framework Agreement-Deployment, permitting Zenith to be a deployment partner of the 5B Maverick system within Australia.

The 5B Maverick system solar array is prefabricated, allowing rapid deployment while increasing the ability of Zenith to expand renewable assets across existing and future sites, Zenith said. Each 5B Maverick array consists of up to 90 solar panels, mounted on specially designed racks, and optimised for the 540-550 W module class of the utility scale solar industry.

Zenith Managing Director, Hamish Moffat, said the partnership represents the next step in reducing emissions across Zenith’s legacy portfolio.

“We’ve been looking to increase renewable assets across multiple sites for some time; the question has always been around how we can achieve that in such a way that is economically viable,” he said. “The 5B Maverick system is re-deployable, meaning it can be integrated on mines with shorter tenure, and moved at the end of operations at those sites.”

He added: “It offers Zenith greater ability to leverage value from our initial capital expenditure, making it more cost effective to offer expanded renewable energy solutions for our clients.”

5B Co-Founder and CEO, Chris McGrath, said the strategic partnership is an important validation of 5B Maverick’s ability to reduce deployment complexity.

“This has been a major barrier for solar installations on mine sites worldwide,” he said. “The agreement also shows that our cost reduction efforts over the past two years have worked – we’ve hit the price point where 5B Mavericks can be viably packed up and redeployed elsewhere, substantially reducing the risk of stranded assets in mining, agricultural and industrial operations.”

Moffat said Zenith is looking to integrate the 5B Maverick system across three sites initially. These include:

  • Nova: The 5B Maverick will play a major role in Zenith’s industry first ‘engine-off’ project at IGO’s Nova nickel mine, allowing the site to operate on up to nine consecutive hours of renewable energy through the installation of an extra 10 MW of solar, and a 10 MW battery energy storage system;
  • Warrawoona: Zenith recently committed to the supply, installation, and commissioning of a 4 MW DC Solar Farm, using the 5B Maverick, as well as a 3 MW/3 MWh AC battery energy storage system at Warrawoona, owned by Calidus Resources. The hybrid power station configuration will reduce gas use, which in turn results in a reduction in emissions; and
  • King of The Hills: Work is currently underway to install 2 MW of 5B Maverick on the Red 5 site, also supported by a battery energy storage system.

Moffat said the 5B agreement is another key milestone on the company’s journey toward ‘net zero’.

“Our 2035 ‘net zero’ target strikes a balance between ambition and ability to achieve, with the 5B partnership a clear demonstration of our progress and commitment to this goal,” he said.

McGrath said 5B was keen to partner with Zenith, given the independent power producer’s strong reputation and credibility in providing renewable energy solutions to the mining and resources industry.

“We’re keen to develop mutually beneficial partnerships with like-minded companies, and Zenith definitely fits the bill,” he said. “It is great to see Zenith leveraging the ability of the 5B Maverick solar arrays to deploy up to 10 times faster, more safely than single axis tracker and fixed tilt solar systems, to deliver a full solution for their customers.”

Moffat said the partnership offers both Zenith and 5B the opportunity to continue to lead the industry, demonstrating the ability and capacity to effectively integrate renewable energy solutions.

“We have continually said we want to be part of the renewable solution, not just by developing the concepts needed, but by also actively deploying and proving the technology,” he said. “The partnership with 5B allows us to do this and continue to bring our clients on the glide path to ‘net zero’.”

Cobham confirms seven-year FIFO extension for Murrin Murrin mine site

Cobham Regional Services has been awarded a new seven-year contract with Minara Resources (wholly owned by Glencore), to provide fly-in, fly-out (FIFO) services to its Murrin Murrin site in the eastern Goldfields region of Western Australia.

Minara Resources is Australia’s largest cobalt producer and a major producer of nickel, and a foundation FIFO client of Cobham.

Cobham Regional Services Managing Director, Claude Alviani, said that Cobham had been providing FIFO services to Murrin Murrin since the mine commenced operations in 1996.

“We are absolutely delighted to continue the relationship we have with Minara as their aviation partner of choice,” Alviani said. “The operators of Murrin Murrin were pioneers of FIFO in Western Australia, using an airbridge to connect workers to site well before it became common practice.

“Over the past six months, Minara has transitioned to our modern, lower carbon emission aircraft with the E190 and Q400 now servicing the site.”

Brett Fowler, General Manager, Minara Resources, said: “We are pleased to continue our relationship with Cobham, a long-term partner of the Murrin Murrin operations. We welcome the addition of the lower carbon emission aircraft to Murrin Murrin as we continue to produce the nickel and cobalt that are critical commodities for the transition to a low-carbon economy.”

The new contract comes at a pivotal time for the industry in Western Australia as the State prepares to open its borders.

Cobham’s Business Development Director, Tim Pirga, said that Cobham was well positioned for transitioning to the next phase of living with COVID.

“We have a private terminal which allows us to offer bespoke solutions for COVID screening, health checks and passenger separation,” he said. “Minara will take advantage of our facility and of our experiences operating in other states where borders have been open for some time.”

Civmec to construct Mount Holland lithium concentrate refinery

Civmec Ltd has been issued with a notice of award for a major construction contract in the resources sector at the Covalent Lithium Pty Ltd joint venture in Western Australia, as well as several infrastructure and maintenance projects, raising its order book to more than A$1.15 billion ($823 million).

The major construction contract is for the Mount Holland lithium project in Western Australia being undertaken by subsidiaries of Wesfarmers and Sociedad Química y Minera de Chile SA through the 50:50 joint venture manager Covalent Lithium Pty Ltd.

The Mount Holland mine site will produce lithium concentrate, which will be transported to a refinery that Civmec has been tasked to construct. The refinery, to be located at Kwinana in Western Australia and within 10 km of Civmec’s flagship heavy engineering facilities in Henderson, will convert the lithium concentrate into high-purity lithium hydroxide monohydrate. Covalent says the refinery operations are expected to have an 85% recovery of the lithium contained in the spodumene concentrate, with the capacity to produce around 45,000 t/y of battery-quality lithium hydroxide.

The scope of work being undertaken by Civmec covers most disciplines performed by Civmec including structural and piping fabrication, SMP erection, refractory lining, insulation and E&I installation works.

Civmec expects to commence work on this project in 2022, with completion expected in 2024.

On top of this, the company says it has also continued to make traction in our efforts to secure more market share in the maintenance area on both the East and West coast of Australia with a new contract award for maintenance services for Glencore’s Murrin Murrin operations. It is also getting more work for maintenance and shutdowns from long-term client Roy Hill, and has recently completed work for a nickel producer in the Goldfields region of Western Australia.

Civmec’s Chief Executive Officer, Patrick Tallon, said: “Demand for heavy engineering and construction services in the private and public sectors in Australia remains strong and these new contracts underscore, yet again, our strength as a top-tier contractor. Our efforts to generate more recurring income are also paying off as we are getting more work involving maintenance and capital works from both existing and new clients.”

Following these Barminco Principles will help create a safer environment for our people and will assist our client in consistently achieving production targets.”

DOK-ING Extra Low Profile Dozer wins plaudits in Australia underground mine site trial

Mine Tech Australia says one of its clients in Western Australia’s Goldfields region is putting a DOK-ING XLPD Extra Low Profile Dozer through its paces.

Back in June, the company said it recently completed DOK-ING XLP system testing and operator awareness training in the lead up to mobilising the unit for this underground mine site trial. That trial is now underway.

“The client’s team on site have been putting the XLPD through its paces in real-life work environments and we have received overwhelming support for its effectiveness, versatility, and application in difficult underground mining applications working alongside their team of handheld mining specialists to improve their turnaround time for scraping-out slots and other development works,” the company reported.

The XLPD Compact Robotic Dozer presents a very low profile remote-controlled machine with the goal of increasing productivity and safety in material handling operations.

Being designed to withstand the most severe working conditions in the mining industry, the XLPD has proven to be a safe and effective asset, Mine Tech, one of DOK-ING’s regional dealers, said.

As part of the Extra Low Profile segment, the dozer is suitable for activities in construction works, cleaning of production panels, sweeping and vamping activities, cleaning under conveyor belts and other hazardous environment operations, it said. This is where numerous attachments such as bucket, ejector bucket, dozer blade, brush and gripper tools come in handy.

Minetek breathes new life into Saracen’s Thunderbox gold mine

Minetek has been chosen to install an interim primary ventilation solution at Saracen Mineral Holdings’ Thunderbox operations in the northern Goldfields region of Western Australia.

Saracen was looking for an innovative ventilation solution to replace the traditional axial fans that were not supplying the required ventilation to increase production at the site, Minetek said.

The METS company said it was able to cater to the client’s needs and offer a custom solution that was installed with minimal disruption.

“We were able to customise a solution that was the same size in diameter to their existing fans but delivered a substantial increase to performance at the same time,” Minetek General Manager for Ventilation, Jeremy Sutherland, said.

Minetek’s POD (Pressure On Demand) technology allows the client to incrementally increase ventilation levels underground when required and give the client control over their energy consumption, the company said.

Saracen Thunderbox Underground Manager, Des Koh, said Minetek fans were selected to upgrade the site’s primary ventilation network, in preparation for a production ramp up, due to their ability to produce almost double the ventilation flow of the previous setup while only taking up slightly more room.

“The relatively small fans allowed us to utilise our existing bulkhead, where we were severely limited by space, which allowed us to use our existing infrastructure and dramatically reduce downtime in the mine during the change out,” Koh said.

“The installation was completed safely by our own personnel with technical support from Minetek and allows us to scale our ventilation flow with their pressure on demand system to suit our production profile.”

BHP Nickel West to reduce emissions with Southern Cross Energy contract extension

BHP has executed a 15-year contract extension to its power purchase agreement (PPA) with energy provider Southern Cross Energy (SCE) for the supply of electricity to its Nickel West operations in the Goldfields of Western Australia.

The agreement extends the current arrangement to 2038, giving Nickel West access to all electricity produced by SCE.

Nickel West Asset President, Eduard Haegel, said the PPA also provided Nickel West with the additional ability to integrate renewable electricity generation, including solar and wind, with energy storage technologies to meet its emissions reduction targets and deliver lower carbon, sustainable nickel to its customers.

Study phases for renewable energy supply and carbon emissions reduction under the extended PPA are underway, including an 18.5 MW solar photovoltaic farm at Nickel West’s Leinster and Mount Keith operations, supported by a battery energy storage system. A 17 MW waste heat steam turbine system at the Kalgoorlie smelter is also being evaluated to provide low-emissions electricity from furnace heat recovery, BHP said.

The combined projects have the potential to reduce Nickel West’s Scope 2 electricity greenhouse gas emissions by up to 15% by 2023, based on 2020 levels.

“These projects contribute to the first phase of our emissions reduction strategy, as we continue to evaluate plans for additional renewable energy supply to decarbonise our nickel operations,” Haegel said.

“We are at the beginning of an energy revolution that will transform our world and materially increase demand for nickel. BHP Nickel West is well placed to provide our nickel units sustainably, and with one of the lowest carbon footprints.”

BHP has committed to a science-based target of a 30% reduction in carbon emissions from 2020 levels by 2030, with a long-term target of net zero operational emissions by 2050.

“Our integrated value chain and the sulphide nature of our nickel deposits makes Nickel West one of the lowest carbon emitters in the industry and gives BHP a global advantage in the sustainable production of nickel,” Haegel said.
