OZ Minerals turns down BHP’s A$25/share cash offer

OZ Minerals says it has rejected an unsolicited, conditional and non-binding indicative proposal from BHP to acquire all shares in the company for A$25/share ($17.3/share) in cash, valuing the company at an reported A$8.34 billion.

Having assessed this proposal, which represents a 13.1% premium to the volume weighted average price (VWAP) of OZ’s share price for the six months prior, the Board has unanimously determined that the offer significantly undervalues OZ Minerals and, as such, is not in the best interests of shareholders.

For its part, BHP points out in a separate press release that the consideration represents an “attractive premium” of 32.1% to OZ Minerals’ closing price of A$18.92/share on August 5 and 41.4% to OZ Minerals’ 30-day VWAP of A$17.67/share up to and including August 5.

OZ Minerals says the proposal is subject to a number of conditions including:

  • The completion of extensive financial, legal, technical and operational due diligence over a proposed six-week timeframe;
  • Various financial assumptions;
  • A unanimous recommendation of the OZ Minerals Board; and
  • Entry into a scheme implementation agreement subject to a range of conditions including no material adverse change, regulatory, shareholder and court approvals and conduct of business restrictions.

OZ Minerals says the Board has been advised by BHP that it has accumulated an interest in OZ Minerals shares via derivative instruments amounting to an interest of less than 5%.

OZ Minerals Managing Director and Chief Executive Officer, Andrew Cole, said: “We have a unique set of copper and nickel assets, all with strong long-term growth potential in quality locations. We are mining minerals that are in strong demand particularly for the global electrification and decarbonisation thematic and we have a long-life resource and reserve base. We do not consider the proposal from BHP sufficiently recognises these attributes.”

In coming to its decision, OZ Minerals says the Board considered that the proposal does not adequately compensate shareholders for:

  • The unique nature of OZ Minerals’ core business which represents a high-quality portfolio of copper and nickel assets, located in a Tier-1 mining jurisdiction with long mine lives, first quartile cost positioning and extensive strategic optionality;
  • The unique investment proposition which OZ Minerals provides as the only primary copper company in the ASX 100;
  • The low carbon intensity of OZ Minerals’ assets relative to its peers with a defined and market- leading plan for further decarbonisation to meet our target of net zero Scope 1 and 2 operational emissions by 2030;
  • The high-quality nature of OZ Minerals’ growth projects which include the West Musgrave project (final investment decision scheduled for H2 2022), the Carrapateena Block Cave and the Prominent Hill Extension which together are expected to generate significant production growth over the next five years;
  • The strong long-term outlook for both the copper and nickel markets underpinned by increasing geological scarcity, global electrification and accelerating decarbonisation, to which OZ Minerals is highly leveraged; and
  • The strong and consistent returns that the OZ Minerals management team has delivered with a total shareholder return of circa-145% over the past five years.

In addition to the above, OZ Minerals would deliver significant synergies and other benefits to BHP which the Board considers are not reflected in the value of BHP’s indicative proposal.

Among there are the operational synergies in both South Australia (between Olympic Dam, Carrapateena and Prominent Hill) and in Western Australia (between Nickel West and West Musgrave).

BHP says the cash offer it has made would deliver immediate value to OZ Minerals shareholders and de-risk any value which may (or may not) eventually be reflected in the company’s share price.

BHP CEO, Mike Henry, said: “Our proposal represents compelling value and certainty for OZ Minerals shareholders in the face of a deteriorating external environment and increased OZ Minerals operational- and growth-related funding challenges.

“We are disappointed that the Board of OZ Minerals has indicated that it is not willing to entertain our compelling offer or provide us with access to due diligence in relation to our proposal.”

Escondida, Spence and Olympic Dam production practices recognised with Copper Mark

BHP’s Chilean operations Escondida and Spence, and Olympic Dam in Australia, have been awarded the Copper Mark, recognising responsible production practices after an independent assurance process, the miner says.

The Copper Mark is an assurance framework specific to the copper industry, developed to ensure value chain participants demonstrate best practice in responsible production and contribute to the United Nations Sustainable Development Goals. Copper Mark is a voluntary program that independently assesses participants in 32 critical areas including environment, community, human rights and governance issues for mining, smelting and refining operations.

The Copper Mark uses the Risk Readiness Assessment (RRA) of the Responsible Minerals Initiative (RMI) and the Joint Due Diligence Standard for Copper, Lead, Nickel and Zinc, as the basis for evaluating participants’ performance.

BHP submitted Letters of Commitment for Escondida (pictured), Spence and Olympic Dam to the Copper Mark Responsible Production Framework on October 31, 2020. The Copper Mark was awarded to Olympic Dam on September 21, 2021, while Spence and Escondida were each awarded theirs on November 2, 2021.

BHP’s Group Sales and Marketing Officer, Michiel Hovers, said: “Long-term sustainability credentials are important to our customers and increasingly important to end consumers of copper products, such as buyers of electric vehicles and copper intensive consumer durables.”

BHP’s Mineral Americas President, Rag Udd, added: “Copper Mark is a step forward in developing an industry-wide approach to transparency and standards for the copper value chain and reinforces the value BHP places on responsible, sustainable production.

“Copper is a future-facing commodity and our operations have an important role to play in providing high quality and sustainable copper that is essential to the energy transition. Escondida, the largest copper producer in the world, operates 100% with desalinated water and, along with Spence, is aiming to achieve 100% renewable power by the mid-2020s.

“It is important to our customers, investors, employees, communities and governments to ascertain the ethical and sustainable production of copper along the value chain.”

BHP Olympic Dam Asset President, Jennifer Purdie, said the team was thrilled that Olympic Dam has become the first site in Australia to be awarded the Copper Mark.

“Olympic Dam is a multi-generational orebody and one of the world’s most significant deposits of copper, gold, silver and uranium,” she said. “The Copper Mark accreditation provides an industry-wide approach to transparency and sustainability in the copper value chain and provides our customers with confidence in the copper they purchase. Award of the Copper Mark will help us to keep sustainably delivering jobs, investment and economic and social value.”.

The Copper Mark’s Executive Director, Michèle Brülhart, said: “We are delighted to welcome Escondida, Spence and Olympic Dam among the recipients of the Copper Mark. We are particularly pleased to see the first Australian site to receive the Copper Mark with Olympic Dam while we continue to grow our footprint in the world’s main copper producing country, Chile. We congratulate the three sites for their achievement and their commitment to responsible production practices.”

BHP closes in on renewable energy supply for Olympic Dam mine

BHP says it expects to shortly enter into renewable energy supply arrangements to enable the Olympic Dam mine in South Australia to reduce its emission position to zero for 50% of its electricity consumption by 2025, based on current forecast demand.

The arrangements will be supplied by Iberdrola, including from the Port Augusta Renewable Energy Park in South Australia, which is expected to be Australia’s largest solar-wind hybrid plant once in operation in July 2022.

BHP is to become the primary customer of this new renewable facility, with the renewable energy supply arrangements referred to including a retail agreement with Origin Energy, who will facilitate the arrangements.

This announcement follows BHP’s entry into renewable energy agreements for BHP’s operations in Western Australia in 2021, Queensland in 2020 and in Chile in 2019.

BHP Olympic Dam Asset President, Jennifer Purdie, said: “These arrangements will support an exciting new renewable energy project which will contribute to South Australia’s renewable energy ambitions.

“Olympic Dam’s copper has an important role to play to support global decarbonisation and the energy transition as an essential product in electric vehicles and renewable infrastructure. Reducing emissions from our operations will further enhance our position as a sustainable copper producer.”

Iberdrola Australia Chief Executive Officer and Managing Director, Ross Rolfe, said: “We are delighted to be partnering with BHP, helping them meet their decarbonisation and sustainability objectives. We worked very closely with BHP to design these bespoke renewable energy supply arrangements. Olympic Dam is to be the primary customer for the Port Augusta Renewable Energy Park, a demonstration of their commitment to local procurement and sustainable economic development.”

The arrangements, intended to commence on July 1, 2022, are one of the actions BHP is taking to contribute to its medium-term target to reduce operational greenhouse gas emissions (Scope 1 and 2) from its operated assets by at least 30% from financial year 2020 levels by financial year 2030.

BHP contracts indigenous-owned Zancott Knight for Olympic Dam refuelling services

In the lead-up to the 20-year rebuild of the flash furnace at BHP’s Olympic Dam mine in South Australia, the miner has awarded a A$1.8 million ($1.3 million) contract for refuelling services to local, indigenous-owned company Zancott Knight.

The flash furnace rebuild is part of the current smelter maintenance campaign, SCM21, at Olympic Dam, with BHP actively seeking out opportunities for local, small and indigenous businesses to be part of the action, Jenny Purdie, Asset President Olympic Dam, told attendees at the Copper to the World Conference in Adelaide, yesterday.

Purdie said Zancott Knight is a local, indigenous-owned company closely connected to the Arabana community. She added that Zancott Knight has brought in a sub-contracting partner, WB Enterprises, who are closely connected to the Kokatha community, to carry out the refuelling services contract.

Both these groups make up two of the Traditional Owner partners Olympic Dam engages with, she said.

BHP’s global operations spend approximately $2 billion with small, local and indigenous businesses each and every year, Purdie added.

Monadelphous Group banks engineering work with BHP, Rio and Codelco

Monadelphous Group Ltd has secured several new construction and maintenance contracts in the resources sector totalling around A$215 million ($163 million).

Included within this slate of new work is a contract for smelter campaign maintenance works at the BHP owned Olympic Dam copper mine in South Australia. Monadelphous said work will commence immediately and is expected to be completed in December 2021.

Monadelphous has also been awarded a two-year extension to its existing maintenance services contract at Olympic Dam. The contract scope includes civil, structural, mechanical, building maintenance and electrical services, as well as the addition of underground rail maintenance services.

In the iron ore sector in the Pilbara region of Western Australia, Monadelphous has been awarded several contracts, including several sustaining capital contracts under its panel agreements with BHP and Rio Tinto; and a contract with Rio for the provision of construction and support services associated with the Gudai-Darri iron ore project, with work expected to be completed by the end of 2021.

In Chile, the company’s maintenance and construction services business, Buildtek, has secured a number of new contracts, including a three-year contract with Codelco for the operations and maintenance of water infrastructure at the Chuquicamata underground mine in Calama. Buildtek has been providing these services on this site since 2018.

In addition, the engineering company has secured two new contracts with Codelco for maintenance activities associated with the concentrator plant at El Teniente mine in Rancagua; and a contract with BHP Minera Escondida for the construction of modularised pump stations and associated infrastructure of the Escondida copper mine in Coloso.

Finally, Monadelphous, in collaboration with global heavy lifting services company Fagioli, has secured a contract with NMT International (Australia) to deliver specialist heavy lifting and haulage services at the Iron Bridge magnetite project, a joint venture between Fortescue Metals Group subsidiary FMG Magnetite Pty Ltd and Formosa Steel IB. The strategic collaboration with Fagioli enables Monadelphous’ specialist Heavy Lift business to increase capacity and broaden capability for the Australian resources and energy markets, it said.

CRC ORE simplifies complexity for value

“There are a lot more variables to bulk ore sorting than just the technology,” Jon Rutter says.

The Principal Geologist of the Cooperative Research Centre for Optimising Resource Extraction (CRC ORE), Rutter knows his stuff. He has worked underground in both narrow-vein and mass-mining operations, as well as at large scale open-pit mines; in the base and precious metal arena.

During a presentation at International Mining Events’ IPCC Virtual event in early-February, he shared a slice of this knowledge while reviewing a recent installation project CRC ORE had been involved in at a platinum group element (PGE) operation.

“The intrinsic value of bulk ore sorting comes from the delivered heterogeneity,” Rutter said. “We have got to be able to sense and divert a higher-value pod of material versus an adjacent pod of lower-grade material on a conveyor.

“You essentially want to put more material into the mill that adds value – and not what destroys value.”

Looking at the wider bulk sorting opportunity in mining, Rutter explained the sensor diversion units (SDU) in bulk ore sorting were smaller than what the mine itself can typically offer in the form of a selective mining unit (SMU), which may be comprised of a dig block totalling around 15,000 t.

A truck offers a 100-300 t opportunity, while a shovel typically comes with a 50-100 t opportunity.

Even with a modest conveyor running at a 2,000 t/h rate, an on-board sensor (eg PGNAA or PFTNA) running at a 30 second integration time (the time to analyse one grade) would provide an SDU of 16.7 t. A sensor with lower integration time (eg XRF at 10 seconds) comes in at 5.6 t.

The ability to provide analysis down to this level has enticed several major companies into testing bulk ore sorting solutions.

Anglo American has trialled bulk ore sorting solutions at copper and platinum group metal mines, while BHP recently engaged CRC ORE to examine deployment of cutting-edge preconcentration techniques under its Grade Engineering® platform at the Olympic Dam mine, in South Australia.

The SDU with bulk sorting may be that much smaller than the SMU of a typical mine plan, but lab-level precision is not required for these solutions to work, according to Rutter.

“What I need is the ability to measure the metal content adequately,” he said. “When I say adequate, this incorporates the entire error bar of the system. That system includes the inherent geology, the mineralisation style and heterogeneity. We also need to consider the precision, accuracy and integration time – which is the technology constraint; but we also need to include the weightometers, the flop gates, the diversion gates, as well as that entire mining and materials handling process right from the start – from blasting, loading, hauling and dumping to the plant.

“But for bulk ore sorting what I end up requiring from this combined data is usually a binary decision: am I above or below a certain threshold?”

He expands on the bulk ore sorting (BOS) assessment process: “The other way of looking at this is simply considering it as planned ore loss and dilution. If we go back into that dig block, in that 15,000 t of material, I’ve already incorporated planned ore loss and dilution decisions or parameters into that SMU decision. So, if we look at bulk ore sorting, I am just talking about those different attributes – the error bars of a BOS system – as the inputs or parameters for BOS planned ore loss and dilution – it’s now just at a smaller and more precise opportunity.”

The company took a two-phase approach to the BOS opportunity at the PGE operation in question.

The first phase involved carrying out heterogeneity analysis of the orebody; correlation analysis of PGEs to base metals; selection of sensor technologies (XRF and PGNAA were selected in this case), design, layout and equipment selection for the bulk ore sorting plant; natural deportment analysis of the orebody; development of a preliminary business case; the ore type selection and sampling strategy; and project planning and management.

CRC ORE and the company in question settled on a solution where a Caterpillar 992 wheel loader dropped material off to a system using a combination of grizzly, feeder, sizer, conveyors, diverter, stackers and associated equipment from MMD, used in conjunction with an ore sensing system equipped with both PGNAA and XRF sensors to continuously measure the elemental composition. The PGNAA sensor provided a “penetrative” analysis calculation whereas XRF provided a “surface” sensing calculation, Rutter explained.

An incline conveyor ahead of the diverter gate and the accept/reject stream provided the 30 second integration time the PGNAA analyser required.

Phase two of the project involved online and offline (pre-install) work; sensor calibration; proving the technology; and proving the technology can drive physical separation.

Rutter said the completion of static calibration of the sensors saw the PGNAA sensor 20-30% calibrated, and the XRF sensor 70-80% calibrated.

This outcome harked back to Rutter’s assertion that “bulk ore sorting implementation is not a plug and play opportunity”.

A dynamic calibration in online mode completed under normal conditions was required to get the PGNAA sensor up to speed. This process, meanwhile, solidified the operation of the XRF sensor.

While the two sensors were calibrated in different ways, Rutter showed data that confirmed both were in unison when it came to reading the ore/waste that came through the conveyor (see right-hand graph below).

“The two sensors are independent of each other and fundamentally very different, but they can work well together, or separately,” he said.

CRC ORE was able to prove the technology by running the same sample through the circuit a number of times, as Rutter explained: “We fed 15-20 t of run of mine material into the hopper and repeated the process 15 times, putting the same 15-20 t sample through the system. We could then start to determine the precision and accuracy of the sensors and the system.”

For further verification, the sample was crushed, sub sampled and assayed.

“We wanted a binary response to ore and waste to build confidence,” Rutter added.

Phase three involved the ramp up to production scale, going from, say, 500 t/h to 1,000 t/h; carrying out validation by campaign; and finally integrating with the operation.

There were several lessons all mining companies – and bulk sorting vendors – should keep in mind from such a project, Rutter said.

Operations need to assess the impact of mixing across the entire materials and mining handling process as soon as possible, for one.

“The earlier we can put this data into the system, the better,” Rutter said. “Without a heterogeneity signature, we cannot implement bulk ore sorting.”

He also stressed the importance of timely feedback. Sensor calibration, a secondary crushing/sampling plant and assaying were all required to build confidence in the solution.

Rutter added: “The proper calibration of sensors does require a considerable and ongoing effort…but that is no different from any other process plant or equipment.”

Operators also need to be wary of where they set these solutions up in mines, recognising this heterogeneity dynamic.

“Bulk ore sorting is quite unlikely to be universally suited to the entire deposit,” Rutter said. “The analogue for this is a flotation plant; there are ore types in the mine where you achieve better performance in the flotation plant and others where you get worse performance.”

BHP commits Escondida, Spence and Olympic Dam ops to reaching Copper Mark

BHP has issued a Letter of Commitment to the Copper Mark Responsible Production Framework that will see its Escondida and Spence operations in Chile, plus its Olympic Dam mine in Australia, fall in line with the voluntary program.

The Copper Mark is a credible assurance framework to demonstrate the copper industry’s responsible production practices and contribution to the United Nations Sustainable Development Goals, BHP said. The program is designed to hold the copper industry accountable to responsible practices in critical areas including environment, community, human rights and governance issues, according to BHP Group Sales and Marketing Officer, Michiel Hovers.

“We know that our long-term sustainability credentials are important to our customers and increasingly important to end consumers of copper products, such as buyers of electric vehicles and copper intensive consumer durables,” Hovers said. “The Copper Mark accreditation is an important step in developing an industry-wide approach to transparency and standards for the copper value chain.”

This year, the Oyu Tolgoi mine, in Mongolia, and the Kennecott operation, in the US, were both awarded the Copper Mark. Freeport McMoRan has also pledged to fall in line with the program at six of its operations.

Hovers added: “The Copper Mark is an independent and credible certification, and will further reinforce the value responsible production of the copper products that we sell to our customers.”

BHP has set targets to reduce its emissions by 30% by 2030, along with a goal of net zero emissions by 2050, Hovers said. In Chile, at Escondida, the company is also aiming to operate using 100% renewable power and 100% desalinated water.

“We know that copper is essential to the energy transition, but equally important to our customers, our investors, our employees, our communities, and our stakeholders across the copper value chain is ethical and sustainable production of copper – where production is in line with the UN’s sustainable development goals,” Hovers said.

BHP’s operated copper assets involved in this transition – Escondida, Spence and Olympic Dam – represented 1.5 Mt of copper production in the miner’s 2020 financial year.

BHP engages CRC ORE for Olympic Dam bulk ore sorting study

BHP has engaged the services of Australia-based research consortium, the Cooperative Research Centre for Optimising Resource Extraction (CRC ORE), to examine deployment of cutting-edge preconcentration techniques.

Olympic Dam, 560 km north of Adelaide, is one of the world’s most significant deposits of copper, gold, silver, and uranium. This large BHP site is made up of underground and surface operations and conducts fully integrated processing from ore to metal.

The South Australia operation is one of the locations where BHP is actively examining bulk ore sensing and sorting opportunities – techniques within the CRC ORE Grade Engineering® suite of preconcentration technologies.

Grade Engineering is an integrated approach to coarse rejection that matches a suite of separation technologies to ore specific characteristics and compares the net value of rejecting low value components in current feed streams with existing mine plans as part of a system-view.

CRC ORE was requested by BHP to assist in the assessment of bulk ore sorting opportunities at Olympic Dam, it said.

BHP Principal Technology, Lee Bolden, said that as a CRC ORE participant, the diversified miner had watched with interest the sorting and sensing work that CRC ORE is undertaking in open-pit and underground operations.

“It made sense for us to have CRC ORE provide us with valuable insights on this work and input into our bulk ore sorting plans,” Bolden said.

BHP received a high-level bulk ore sorting deployment strategy from CRC ORE for Olympic Dam, along with a framework and calculator for the quantification and ranking of bulk ore sorting strategies at the operation.

CRC ORE also identified the critical work and data required to strengthen the evaluation of bulk ore sorting with the Olympic Dam Project team.

CRC ORE Chief Operating Officer, Dr Luke Keeney, said there were several deployment options among the opportunities assessed.

“We explored sublevel open stoping under the current mining environment, along with block caving as part of future-state mining options,” Dr Keeney said.

As part of the assessment, BHP received a high-level estimate of value from these deployment options.

Dr Keeney said the engagement of CRC ORE at Olympic Dam demonstrated the commitment of big miners to apply innovation to their processes.

“With the need for valuable minerals continuing to grow and mining these minerals becoming ever more difficult, mine operators need to think differently,” Dr Keeney said.

“Bulk ore sorting, and other Grade Engineering opportunities become increasingly competitive and complementary solutions where mined grades decline and mining dilution increases.”

Data science competition unearths potential of South Australia’s Gawler region

Unearthed Solutions says scores of multi-billion-dollar mining projects could be ignited following the results of an international challenge to unlock the potential of South Australia’s resource-rich Gawler region.

ExploreSA: The Gawler Challenge, run by the South Australian Government and innovation specialists Unearthed Solutions, had a total prize pool of A$250,000 ($183,249) and attracted broad domestic and international interest.

Using the Geological Survey of South Australia’s (GSSA) historical records, primary data and research, the competition combines geological expertise with new mathematical, machine learning and artificial intelligence to increase the number of potential drill targets across central South Australia, Unearthed says.

Buoyed by its success, the South Australia Government has allocated an additional A$5 million from the Economic and Business Growth Fund to the GSSA to flesh out the winning concepts into prospects for exploration companies to make the next big discovery, Unearthed said.

Minister for Energy and Mining, Dan van Holst Pellekaan, said he was pleased to congratulate the first prize winner, Per-OZ, for its innovative entry which brings together traditional geology, machine learning, advancing modelling, and precision drilling.

“Team Per-OZ, short for Peru/Australia, is a collaborative effort by Dr Paul Pearson from Latin Global and Dr John McLellan from GMEX who both specialise in structural geology, prospectivity analysis, data science, machine learning and modelling,” van Holst Pellekaan said.

“The judging panel chose the solution presented by Per-OZ as the best overall submission due to their unique methodology which could help geologists in the field find that needle in the haystack. Their unique approach may put us one step closer to uncovering new economic mineral deposits in one of the most significant iron oxide copper-gold regions in the world.”

He added: “By looking at traditional geology with techniques from other disciplines, we can peer into the depths of the earth in a new way, and might just uncover the next Olympic Dam or Carrapateena.”

The Minister for Energy and Mining added that the competition drew around 2,200 data specialists from more than 100 countries to interrogate massive holdings of new and historical data held by the GSSA across the Gawler Craton.

“Globally, it’s becoming harder to find new mineral deposits, and the next generation of discoveries will need to go beyond traditional geology,” he said.

“The analysis of this information treasure trove by data and geoscientists in just five months is an amazing leap forward in the use of artificial intelligence, machine-learning algorithms and alternative mathematical data analysis for the mining sector.

“The GSSA will use this new funding to develop, validate, and deliver publicly available Next Generation Mineral Systems maps for explorers.”

Unearthed Solutions Director, Justin Strharsky (pictured), said “ExploreSA: The Gawler Challenge is a clear demonstration of the South Australian industry’s commitment to harnessing the power of data.

“The world is more interconnected than ever, and the Gawler Challenge has shown that the future will be shaped by those who embrace innovation and collaboration. South Australia is set to reap huge economic benefits and is sending a positive, forward-thinking message to students and international investors that this is where the future lays.

“All mineral targets, models and data will be made publicly available to encourage companies to explore for new deposits in the Gawler region, reinforcing South Australia’s reputation as the centre of mining excellence and innovation in Australia,” he said.

The category winners for ExploreSA: The Gawler Challenge are:
• Overall Winning Submission Per-OZ (A$100,000 prize);
• Runner Up Caldera Analytics (A$50,000 prize);
• Undercover Award DeMIST (A$15,000 prize);
• Rock Licker Award Jack Maughan (A$15,000 prize);
• Future Data Award Sam Bost (A$15,000 prize);
• Breaking New Ground Award Avant Data Solutions (A$15,000 prize); and
• Student Prize Sparveon (A$20,000 prize)

Unearthed Solutions has compiled all targets generated by the challenge into an interactive map, which can be found on the Unearthed website from 16 September 2020.

Monadelphous expands BHP relationship with iron ore, coal, Olympic Dam work

A month after securing several major contracts with BHP, Monadelphous Group has announced another series of works packages with the major miner that come with a combined value of around A$120 million ($87 million).

Two of the construction and maintenance contracts were awarded under its WAIO Asset Panel Framework Agreement with BHP.

This includes a contract to provide structural, mechanical and electrical upgrades at the Newman Hub site in the Pilbara of Western Australia, where work will commence immediately and is expected to be completed before the end of 2021.

The second agreement is at BHP’s Jimblebar iron ore mine site, in Newman, where the company will be dewatering surplus water from the operation.

In addition, Monadelphous has entered into the Olympic Dam Asset Projects Framework Agreement with BHP to provide multi-disciplinary construction services at the Olympic Dam copper mine, in South Australia (pictured). The first contract secured under this agreement is for the supply and construction of acid storage tanks and connection to the existing operating acid plant.

Finally, the company’s Maintenance and Industrial Services division has been awarded a contract to undertake a major dragline shutdown for BHP Mitsubishi Alliance at its Saraji coal mine, located near Dysart, Queensland. The work will be completed by the end of December 2020.

Last month, Monadelphous’ latest construction and maintenance contract awards from BHP included a contract for the supply and installation of the Jimblebar Transfer Station project, and a contract for the refurbishment of Car Dumper 3 at Nelson Point, Port Hedland.
