BHP takes next step in smelter, refinery expansion at Copper South Australia

Base metals, Mine operation news, Sustainable mining, , , , , , ,

The South Australian Government has announced the commencement of an application and assessment process for BHP’s planned smelter and refinery expansion at Olympic Dam via a notification in the South Australian Government Gazette.

The notification is a step forward for BHP’s copper growth plans in South Australia and follows an update in the company’s financial year 2024 full-year results last week, which outlined a phased strategy to increase production in South Australia to 500,000 t/y of refined copper cathode by the early 2030s and then potentially up to 650,000 t/y by the mid-2030s – up from circa-322,000 t last financial year.

BHP Asset President Copper South Australia, Anna Wiley, said: “Today’s announcement is an important step for BHP and the South Australian Government as we work together towards our shared ambition to significantly increase copper production in this state.”

“We are already growing BHP’s copper production in South Australia with projects and studies underway at all of our operating sites, and we’re moving at pace to potentially double our current production by the middle of the next decade.”

BHP’s copper province in South Australia comprises the Olympic Dam, Prominent Hill and Carrapateena underground mines, which provide volumes of copper concentrate to a centralised smelter and refinery complex at Olympic Dam that produces refined copper cathode. The company is also progressing the Oak Dam exploration prospect.

BHP, last week, announced an inferred resource at Oak Dam of 1,340 Mt at 0.66% Cu and 0.33 g/t Au, within which is a mineralisation area that contains 220 Mt at 1.96% Cu and 0.68 g/t Au (at a 1% copper cutoff grade).

A final investment decision on phase one of the smelter and refinery expansion is currently scheduled in the first half of financial year 2027.

Byrnecut rolls out first Sandvik battery-powered jumbo in South Australia

Contract miner Byrnecut has taken the next step on its journey towards expanding its battery-electric equipment fleet with the roll-out of the Sandvik DD422iE development drill with dual controls at the BHP-owned Prominent Hill mine in South Australia.

The drill is the first battery-electric Sandvik development drill in operation in Australia.

Byrnecut took delivery of the battery electric jumbo at Prominent Hill copper mine in December 2023. The machine was put to work alongside Byrnecut’s existing fleet of diesel-powered equipment, including Sandvik development drills, production drills, cable bolters, trucks and loaders. Five months on, drill operators and Byrnecut management alike are impressed by the jumbo’s reliability and its contribution to a cleaner, quieter underground environment, Sandvik reports.

Technical Services Manager at Byrnecut, Dave Taylor, said th Sandvik DD422iE jumbo has “fitted in exactly” as a diesel-powered drill would have, working as it is designed to.

“It’s got all the pros that you would expect, just without all the fumes that come out of the diesel engine,” he added. “We always want to be at the forefront of technology and to look for ways to reduce emissions and diesel particulates – and this is one way of doing that.”

Taylor says the roll-out was simplified, as the Sandvik DD422iE charges by using the same electrical infrastructure used to power the rock drills on the diesel-powered jumbos. “The jumbos we currently have use their diesel engines to tram around but are plugged in and the rock drills run off thousand-volt power via a trailing cable,” he says. “There’s was no additional infrastructure because the DD422iE is charging using what’s already there in the diesel version.”

In a typical scenario, the Sandvik battery-electric jumbo will tram to the work site using electricity stored in its battery. While drilling is underway, the battery is recharged via the patented Sandvik Charging While Drilling technology, allowing the machine to tram away once the drilling cycle is completed.

General Manager for Byrnecut Australia, Craig Barendrecht, says the feedback he has received on the drill is positive despite some initial reservations. “It’s fitted in seamlessly and we’ve had no dramas with operating a battery drill amongst the standard diesel fleet.”

Barendrecht says with Byrnecut planning to increase their battery-electric equipment fleet, the performance of the jumbo is encouraging. “We’ve never previously seen a massive market for the battery jumbo because of the restrictions around tramming distances,” he says. “This is helping to dispel some of those preconceived concerns with how to actually fit an electric jumbo in amongst the traditional diesel fleet.

“This is just an incremental step in getting to that ultimate point where we run a full electric fleet of drills and loaders and trucks.”

Maintenance Superintendent, Mark Noden, says there was an initial learning curve around maintenance requirements for the battery electric rig. However, from an operator perspective it is simple to step from the diesel model to the electric. “I have had no complaints and the support from Sandvik is always good,” he says.

Nathan Cunningham, Business Line Manager for Underground Drills at Sandvik Mining and Rock Solutions, says Byrnecut has consistently demonstrated that it is a forward-thinking mining business, and the purchase of the Sandvik DD422iE reinforces this. “Byrnecut’s trust in the Sandvik product has paid off with the rig operating exactly as it was expected to.”

The Australian Government says it is making the BHP Olympic Dam mine, in South Australia, cleaner and creating jobs by supporting a wind farm and battery project.

The Clean Energy Finance Corporation (CEFC) is investing A$99 million ($64 million) to boost Neoen’s Goyder wind farm – which will provide electricity to BHP’s copper mine in the northern part of the state. This cleaner and cheaper renewable power will be backed up by Neoen’s Blyth Battery, which is located nearby.

Once completed, the wind farm will generate 203 MW of electricity, and the battery will store 477 MWh, enough to help meet half of Olympic Dam mine’s electricity needs with clean power.

The Minister for Climate Change and Energy, Chris Bowen, said the project is important for the South Australian clean energy and resources sectors.

“It’s great to see clean energy powering mining – bringing together key national industrial strengths in renewables and resources, while creating jobs,” he said. “The Albanese Government is excited to support a project that involves three vital things for Australia’s future – wind power, batteries, and strategic materials.”

Blyth Battery is the fifth big battery project financed by the CEFC, bringing their total investment in this technology to over A$390 million.

CEFC CEO, Ian Learmonth, said: “The challenge of reducing emissions across the economy starts with the energy sector. The offtake agreement with BHP demonstrates how reducing energy emissions accelerates decarbonisation across the economy. This innovative solution to provide firmed green energy at Olympic Dam enables a significant energy user to progress its net zero goals while producing a critical mineral like copper more sustainably.”

Neoen CEO, Louis de Sambucy, said: “We are delighted to announce the joint financing of the second tranche of Goyder South Stage 1 alongside Blyth Battery and we sincerely thank the lender group for their trust and commitment. We are looking forward to powering BHP’s Olympic Dam mine with baseload renewable energy.”

Raising Australia achieves Rotary Vertical Drilling System record at Wira Shaft

Byrnecut Group’s specialist raise drilling company, Raising Australia, has announced a new Rotary Vertical Drilling System (RVDS) record at the BHP-owned Prominent Hill operation in South Australia.

A total of 702.6 m of development over 324.19 hours makes the pilot hole at the Wira Shaft the longest single unit pass, top to bottom using a MICON RVDS, Raising Australia says.

The previous record set in 2013 was surpassed late last month as part of the shaft sinking project at Wira.

Byrnecut was awarded the Wira shaft work when the mine was under ownership of OZ Minerals – which recently became part of BHP.

BHP noted in its full year results to end-June 2023 that the Wira shaft mine expansion project was under construction. The hoisting shaft is expected to extend the mine life to at least 2036 and may provide access to potential mineralisation outside the current mine plan, it added.

The RVDS is a pre-programmable, self-steering device for drilling vertical holes. It consists of two modules integrated in the lower part of the bottom hole assembly between the drill bit and the first string stabiliser. A read-out unit consisting of a pressure transducer, an interface unit and a computer in the driller cabin complete the system.

In more than 450 projects around the world the RVDS has proven its reliability and accuracy, according to MICON, with, on average, the RVDS pilot holes deflecting less than 0.1% over the drilling distance.

OZ Minerals navigating Carrapateena mine traffic issues with Mobilaris solutions

OZ Minerals, through the implementation of Mobilaris Situational Awareness and Mobilaris Onboard, has improved traffic flows at its Carrapateena copper-gold mine in South Australia, according to a recent case study.

Having implemented the solutions from Mobilaris, owned by Epiroc, the mining company gained a better understanding of where machines and people were physically located underground – and operations became safer.

Since commencing production in December 2019, the Carrapateena mine has become, over the past decade, one of the biggest mining projects in the state. The ore must be hauled from the production levels to the crusher level via a short decline with limited passing areas, which poses challenges.

To optimise haulage flows, OZ Minerals deployed Epiroc’s Mobilaris Mining Intelligence decision support system to digitise the mine.

Daniel Bruce, Superintendent, OZ Minerals Carrapateena, said: “We saw potential to remove some of the constraints we have underground. You can’t see around corners, and you can’t see through rock, so understanding where things are – where people and machines are – is a lot more difficult than in a typical workplace on the surface.”

OZ Minerals rolled out the first feature in 2019: Mobilaris Situational Awareness, a solution for surface control room operators. Mobilaris Onboard, a solution for underground operators in vehicles, followed in 2021. Thanks to real-time 3D visualisation, anybody with access to a tablet or a PC can quickly understand where machines are operating, according to Epiroc.

“Mobilaris Situational Awareness allows you to see, live, at any point in time, where all the equipment and people are in the mine,” Bruce said. “It also allows you to navigate to locations, equipment and refuge chambers.”

OZ Minerals had initially installed Wi-Fi tags on all its vehicles, which provided accuracy to around 150 m. With Mobilaris Onboard, it can achieve location accuracy of 5-10 m without any extra infrastructure, and all that is needed are basic OBD2 adapters or a Doppler radar, Epiroc says. Implementation started with trucks and loaders, and now the entire underground fleet has been equipped.

This has significantly improved real-time position information, according to Amelia Schmidt, Senior Technician in the site operations team at Carrapateena.

“Everyone at the site operations centre – dispatchers, mine controllers and haulage control – is now using Mobilaris Situational Awareness,” she said. “Previously, it could take quite a bit of time to search for a piece of equipment, but it only takes seconds now to see its last location.”

The system also helps OZ Minerals with its fleet management – to determine where trucks are, for instance – thus becoming a tool in the decision-making process.

Schmidt said: “For those who are perhaps new to the mine, we’ve been able to insert points of interest on the map, for example where it is best to hold. Cycle times are well managed, despite underground operations becoming a lot busier.”

OZ Minerals then implemented a second Mobilaris feature: Mobilaris Onboard, a tablet in a vehicle that acts just like a car navigator but without any need for a dedicated tracking infrastructure. This provided everyone underground with a tool that enabled them to easily understand how equipment was positioned around them.

Bruce added: “This is another piece of information that the operator can use to make a decision – and all of these minute decisions add up to a more productive and safer workplace.”

For Carrapateena Truck Captain, Joel Dodd, everyday work has become easier thanks to Mobilaris Onboard.

“One of the main benefits is that we’re able to travel down and get to our locations a lot better,” he said.

OZ Minerals now has around 200 tablets in vehicles underground – in trucks, LHDs, face drill rigs and light vehicles – and the feedback has been very positive.

“When people can see more clearly where other people are, it helps them avoid unwanted interaction,” Bruce said.

OZ Minerals breaks through at Carrapateena sub-level cave

Base metals, Mine operation news, Mineral project development, Precious metals, , , , ,

OZ Minerals has announced that the Carrapateena cave safely propagated to surface on December 29, 2022, marking the transition from development to production planning at the operation in South Australia.

OZ Minerals Managing Director and Chief Executive Officer, Andrew Cole, said: “The Carrapateena cave safely breaking through to surface marks a significant milestone for the mine and an important de-risking event for ongoing operations. With the cave now through to surface it enables mine planning to be optimised for production rather than prioritising the safe development of the cave, which has been the primary focus over the first two years of the mine’s life.

“I’d like to take this opportunity to congratulate the Carrapateena team for their dedication and focus to deliver a safe working environment and successfully managing the cave propagation to surface.”

Close to a year ago, the Crusher 2 level for the sub-level cave mine at Carrapateena was reached, enabling commencement of the Block Cave Expansion declines and an increase in sub-level cave production rates to from circa 4.7 to 5.0 Mt/y from 2023.

The expansion, which will involve converting the lower part of the current sub-level cave into a series of block caves, is expected to prolong operations at the copper-gold mine, while boosting production to 12 Mt/y. This will see average copper production come in at 110,000-120,000 t/y and gold output average 110,000-120,000 oz/y from 2026, compared with production of 55,262 t and 89,778 oz, respectively, in 2021.
