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.”

Austin expands service offering with Mader Group strategic support alliance

Austin Engineering Ltd has executed a strategic support alliance with Mader Group Ltd that will see Mader provide assistance as required on a flexible ‘tap-on tap-off’ basis, using its mine-based personnel and workshop facilities to bolster Austin’s existing support services.

The initial focus of the alliance will be Western Australia’s Pilbara and Goldfields regions, in addition to sites in Queensland and New South Wales.

Mader, Austin says, is the largest independent provider of equipment maintenance services in Australia and has a growing global presence. Its workforce is based in and around Australia’s key mining regions, allowing for faster deployment to site and overall response time.

Austin will continue to use its own service teams, which travel to site from Perth, Brisbane and Mackay, but will augment these as necessary to improve turnaround times and service efficiency when commercially appropriate.

Mader Group provides services for the inspection, maintenance and repair of heavy mobile equipment. Its technicians offer mechanical and electrical maintenance including fabrication and welding services.

Austin CEO and Managing Director, David Singleton, said: “Austin’s leading engineering and design capabilities see it produce mining truck bodies and buckets for customers across all commodities and global geographies. The agreement with Mader will support our existing services, initially in Australia, to ensure our customers are given the best quality support for our products.”

Barminco to debut Epiroc Diamec Smart 6M in the Goldfields of Western Australia

Barminco says it has become the first company in the world to debut the new generation of Epiroc’s Mobile Carrier Rig (MCR) – the GEN 2 Epiroc Diamec Smart 6M.

This second-generation underground mobile core drill rig uses the drilling capacity of the Diamec Smart 6 automated operating system, and the mobility and sturdiness of the S2 Boomer carrier with the addition of Epiroc’s automated rod handler, the contractor said.

Epiroc says the the Diamec Smart 6M combines the best of two worlds – the high productivity and accuracy of a Diamec core drilling rig, with the mobility of a robust carrier designed for underground use.

The Rod Handling System, coupled with the Smart 6 Rig Control System, allows for full automation, increasing operator safety and productivity, according to Barminco.

The company said: “Combining Epiroc’s cutting-edge technology of their drilling and rod handling operating systems brings the underground drilling industry a step closer to having ‘no hands on steel’ and taking a giant step forward towards a safer environment for the operators.”

The contractor is due to commission the rig next month at a client site in the Goldfields of Western Australia.

Barminco added: “The addition of the Epiroc GEN 2 MCR to our state-of-the-art fleet supports our Diamond Drill team to Enable Tomorrow, work Smarter Together and take No Shortcuts. 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.

Barminco, Ausdrill transport Rhino 100 raise borer to Regis’ Rosemont gold mine

Having become the first company globally to have taken delivery of a mobile raiseboring machine with uphole, downhole, and back reaming capability, Barminco is transporting a Rhino 100 Raise Borer to another client site in Australia.

With the help of its Perenti surface mining partner, Ausdrill, the newest addition was recently transported to Regis Resources’ Rosemont gold mine in Western Australia.

Just last year, Barminco sealed a three-year underground mining services contract with Regis at Rosemont, which has been transitioning from open-pit to underground mining at the operation.

Barminco said: “Through safe and rapid mobilisation, we are able to meet our clients’ needs and transport our equipment across multiple sites to complete a range of drilling campaigns.”

Since April 2019, Barminco’s first Rhino has travelled a combined 15,000 km between four client sites in the Goldfields of Western Australia, drilling a total of 3,843 m.

The Rhino is manufactured by TRB-Raise Borers in Finland but is equipped with Sandvik tools and is distributed by Sandvik. It is a fully mechanised and self-contained electro-hydraulic mobile raiseborer designed for slot raising in underground mining. The latest models also have an optional back reaming module.

In addition to helping transport Barminco’s latest Rhino to Regis’ site, Ausdrill has recently added a new Boart Longyear LF™160 drill rig and FREEDOM™ Loader combination to its diamond drilling fleet.

This rig reduces the crew’s “Hands On Steel” interaction, while improving overall safety standards, Ausdrill said.

When paired with the FL262 FREEDOM Loader, the LF160 combination is ideal for contractors who want to target sophisticated surface drilling exploration contracts that stipulate some of the highest safety standards, without compromising on productivity, Boart Longyear says.

Ora Banda’s Davyhurst gold mine restart to be powered by LNG

Ora Banda Mining and Wesfarmers’ liquified natural gas business, EVOL LNG, have signed a new long-term agreement to bring LNG to the Davyhurst gold mine in Western Australia’s Goldfields region.

The gold mine is aiming to restart production in January 2021 after being placed into care and maintenance in 2018.

Ora Banda’s definitive feasibility study (DFS) for the Davyhurst Restart project outlined a production target of 418,000 oz of gold over an initial five-year mine life based on an ore reserve of 460,000 oz (6.1 Mt at 2.4 g/t Au) from six deposits within 50 km of the existing 1.2 Mt/y plant. The plant is being refurbished by GR Engineering Services.

EVOL LNG’s Manager, Nick Rea, said the business had proven its winning LNG solution to the mining industry over the past 12 years with its customer base continuing to grow.

“We are excited to support the Davyhurst mine back into production,” he said. “Ora Banda is now our ninth mining customer and we are keen to provide them with the benefits and value that are afforded to EVOL LNG’s customers.”

EVOL LNG will build, own, operate and maintain the on-site LNG storage and vaporisation facility at the mine. The facility will use EVOL LNG’s modular design, which, the company says, allows for fast installation and expandability if the mine’s energy requirements increase in the future.

Ora Banda Mining’s Managing Director & CEO, David Quinlivan, said: “Ora Banda’s agreement with EVOL LNG has enabled the company to secure a stable long-term energy solution for Davyhurst on terms consistent with those outlined in the DFS. The use of LNG as the primary fuel source for the Davyhurst power station also provides significant
environmental benefits.

“The company estimates its power generation greenhouse gas emissions will be reduced by approximately 25,000 t during the initial five years of operation when compared to conventional diesel power generation.”

The mine will use EVOL LNG to fuel a 7.5 MW gas-fired power station, with supply planned to commence from December 2020.

The LNG will be supplied from EVOL LNG’s Kwinana production facility in Western Australia, which was expanded earlier this year. Planning is underway for the next expansion to meet the growing market demand.

CRC ORE’s Kal Hub integrated into Curtin University’s WA School of Mines

The Kalgoorlie-Boulder Mining Innovation Hub, an initiative of the Cooperative Research Centre for Optimising Resource Extraction (CRC ORE), has, this week, transitioned to be part of Curtin University’s Western Australian School of Mines (WASM).

The Kalgoorlie-Boulder Mining Innovation Hub has been operating out of the Chamber of Mines and Energy (CME) office in Kalgoorlie, Western Australia, since 2018. It was established in the renowned Goldfields mining community thanks to a partnership between CRC ORE, Curtin University, the Minerals Research Institute of Western Australia, the City of Kalgoorlie-Boulder and CME.

CRC ORE Chief Operating Officer, Dr Luke Keeney, said he was pleased that the Kal Hub has become part of WASM and will continue this collaborative innovation.

“We are proud of what has been achieved through the Kal Hub since its inception and look forward to seeing great things under its new stewardship,” Dr Keeney said. “It is an optimal outcome that Curtin University, one of our valued Research Participants and key partner in the hub to date, is ensuring the future of the Kal Hub as a centre of mining innovation for Western Australia and beyond.”

Curtin University Kalgoorlie Campus Director, Sabina Shugg, said the Kal Hub is a welcome addition to the local campus.

“The Kalgoorlie-Boulder Mining Innovation Hub is growing in stature and already has strong ties to the University, WASM and the local community,” Shugg said. “It is fitting that the Kal Hub is now operated locally to focus on innovations and solutions for the local mining industry.”

Reflecting on the hub and its achievements while operating as a node of CRC ORE, Dr Keeney said the flagship Integrated Screening and Particle Sorting project was a standout.

“This collaborative study with Australian mining companies BHP, Norton Gold Fields and Saracen on the integration of screening and particle sorting techniques is delivering benefits across the resources sector,” Dr Keeney said. “Run through the hub, this study developed a robust and scientifically rigorous framework for collecting, testing and reporting results for integrated screening and particle sorting techniques in a variety of ore domains.”

Dr Keeney said the hub creates opportunities for innovation, collaboration, employment and education.

“We’re particularly proud of being able to engage students – mining’s future brightest minds, with the hub through the vacation student program,” he said.

As part of the transition, Kal Hub Technical Adviser, Dr Laurence Dyer, now works full time for Curtin University. He divides his time between hub projects and his existing role as Curtin’s Discipline Lead for Metallurgical Engineering.

“I’m looking forward to continuing to support collaborative innovation throughout the Goldfields region and beyond,” Dr Dyer said.

Curtin University is planning several new initiatives for the Kal Hub including scaling up an existing major water management project and new partnerships with leading mining technology providers.

RCT helps Evolution Mining transition to fully-autonomous operations at Mungari

RCT says it has successfully commissioned Evolution Mining’s underground LHD fleet at the Mungari gold mine with RCT’s proprietary ControlMaster® automation technology.
