Bardoc Gold has signed a letter of intent (LoI) with GR Engineering Services that confirms its status as preferred tenderer for the engineering, procurement and construction (EPC) contract for the processing facility and associated infrastructure at the Bardoc gold project near Kalgoorlie in Western Australia.

The appointment of GRES as preferred tenderer represents another significant step for Bardoc as work continues to accelerate on key project optimisation strategies aimed at streamlining the mining and production schedule, growing the production rate and improving project economics and returns, Bardoc said.

It follows Bardoc recently initiating a Cash-flow Optimisation Study, which is aimed at increasing the forecast production rate, margins and cashflow of the project. The definitive feasibility study, published earlier in the year, outlined a 2.1 Mt/y project with average annual gold sales of 135,760 oz over 8.2 years of mill production.

The LoI contemplates Bardoc working closely with GRES to complete the optimisation work currently underway as the company moves towards project financing and a Final Investment Decision before the end of the year.

Further updates on the optimisation work will be provided in the coming weeks, with results expected to be provided to the market by the end of August, Bardoc said.

GR Engineering has recently completed the construction of several comparable processing plants in Western Australia, according to Bardoc.

Progressing from the current LoI to a formal EPC contract will be subject to various conditions, including board approvals, project financing, statutory approvals and final contractual pricing and terms.

Bardoc Gold CEO, Robert Ryan, said: “Bardoc is moving rapidly towards the development of a new high-quality, high-margin gold project near Kalgoorlie. The competitive EPC tender process has drawn a number of quality submissions, reflecting the rapid progression of the Bardoc Gold Project and the high-quality work completed as part of the definitive feasibility study.

“The appointment of GR Engineering marks another key step in the development of the project and establishes an important relationship with a leading design and construction group. We look forward to working with the GRES team over the coming weeks and months.”

Curtin University is to open a new research lab geared towards carbon-neutral metal production paths at its Kalgoorlie campus in Western Australia.

Curtin’s WA School of Mines: Minerals, Energy and Chemical Engineering Head of School, Professor Michael Hitch, said the Kalgoorlie Metals Research Laboratory would explore cleaner alternatives through teaching and research that would pave the way for a greener future for the industry.

“The Kalgoorlie Metals Research Laboratory will provide undergraduate students with practical education in carbon-neutral metal production paths, which is particularly important given they are the generation that will help decarbonise the mining industry in the most challenging area of pyrometallurgy,” Professor Hitch said.

Iron ore processing expert, Dr John Clout, has been appointed the Professor of Practice in Pyrometallurgy at the lab with Curtin’s WA School of Mines Kalgoorlie Director, Sabina Shugg, saying he would oversee a high-tech laboratory, fitted with experimental high temperature furnace equipment, capable of simulating the complete industrial process to test renewable energy and green hydrogen sources in the metal extraction process of pyrometallurgy, which currently require fossil fuels.

“Highly respected in the field of pyrometallurgy, Professor Clout will bring real-world experience to the laboratory’s teaching and research, ensuring we contribute to a sustainable future for the Western Australia resources industry,” Shugg said.

Professor Clout said he was thrilled to support the new research hub’s development as an internationally-recognised laboratory and pilot-scale pyrometallurgical research facility for undergraduate teaching and applied research.

“The Kalgoorlie Metals Research Laboratory will aim to develop end-to-end production paths that set new standards for efficiency, value and carbon neutral management, which will ultimately support a cleaner future,” he said.

“After working in the gold, iron ore and nickel industries for more than four decades, I am especially excited to be working with the future leaders of the resources sector to find the most efficient renewable energy sources and processes for pyrometallurgy.

“There is significant potential for industry to be extracting and producing critical metals right here in Western Australia, especially in the Goldfields where there is significant scope for renewal energy production, untapped critical mineral resources, an existing infrastructure network and workforce.”

The Kalgoorlie Metals Research Laboratory has been established as the result of a A$600,000 ($443,697) grant from Curtin University.

The new research facility is also seeking support from industry and private donors for the purchase of additional equipment and ongoing industry-funded projects.

Insig Technologies says it is partnering with the Ampcontrol Group of Companies to establish a service centre in Kalgoorlie, Western Australia, to support, repair and service Ampcontrol products for the Western Australia market.

Insig Technologies will also be a distributor for the Ampcontrol multifunction outlet starter, Rockstarter, for underground hard-rock mining, tunnelling and other industrial applications.

In late May, Insig Technologies and Ampcontrol signed a memorandum of understanding to establish the foundation for the partnership and have now advanced the new association to service market and customer needs.

“We believe the partnership will further enhance Insig Technologies offerings in the underground mining electrical services domain and provide a one-stop-shop for Ampcontrol customers in Western Australia,” Insig said. “We look forward to working with existing and new Ampcontrol customers under this new partnership arrangement.”

Ampcontrol says its Rockstarter is a multifunction outlet starter that, compared with traditional starters, has been custom engineered, designed and built for specific applications. It controls a single power outlet, rated up to 250 A/1.1 kV and incorporates an integrally designed circuit breaker, contactor and all protection electronics into a single unit.

“The versatile unit can be re-used for a wide range of applications, including all normal pump, fan and drill rig applications,” the company said. “The Rockstarter can also be scaled to suit specific applications, allowing multiple units to be connected in a series to supply all active operations in an area.”

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.

MICROMINE makes a software splash at Diggers & Dealers

With Western Australia one of MICROMINE’s key markets for its Micromine and Pitram products, it is hardly surprising the software leader chose this week’s Diggers & Dealers Mining Forum in Kalgoorlie to reveal a host of new updates for the 3D modelling and mine design/mine production and fleet tracking solutions.

Across the company’s product suite, MICROMINE has been readily engaging with customers throughout the world, with users providing feedback to form its product roadmaps.

One of the results of this consultation process is a move to a six-monthly release cycle to enable its software to grow and adapt with clients’ operations.

Another is providing networking options to expand usage of its software across a wider number of users – the free Micromine Effects reader enabling anyone to view, share and interrogate Micromine output files without needing access to a full software licence.

“We’ve also introduced subscription offerings which our customers have quickly adopted because they provide a flexible and scalable option for large teams to access more functionality across our product suite, with less upfront cost compared to the traditional perpetual model,” Adam Brew, MICROMINE Australia Manager, told IM.

Shifting any capex item to the opex column is bound to go down well with the mining community, as MICROMINE has shown.

Having occurred in August 2019, the move led to almost nine months straight of subscription-only sales, according to Brew. “It surpassed our expectations,” he said. “The ability to have a subscription model allowed us to then launch the Free April campaign.”

The “Free April” campaign – which saw MICROMINE offer miners complimentary access to its general mining Micromine package during April as COVID-19 started to bite – led to around 4,000 new people interacting with the software, according to Brew.

MICROMINE has been busy on updates during the pandemic, but it has also delivered its first fully remote implementation of Pitram at a mine operation in Greece, leveraging the experience from its global Pitram support desk to fully deploy a Pitram FMS and Material Management solution.

This Greek project is well advanced with Pitram playing a crucial role in a major refurbishment and expansion of existing operations. The solution at the mine is aimed at helping improve development and production mining cycles; accurately track materials from source to processing; provide Online Analytical Processing reporting and analysis; enhance reactions to, and minimise the impact of, unplanned events; and increase equipment availability and utilisation.

Yet, those attending the MICROMINE booth at Diggers & Dealers this week will have even more to talk about.

Something new

“Micromine 2021 is scheduled for release later this year and attendees of Diggers and Dealers will be the first to get a pre-release reveal of our flagship software offering,” Brew said.

Australia, in particular, has bucked global trends in terms of exploration expenditure, and the Micromine value proposition has been central to the company capitalising on this resurgence in exploration activities, according to Brew.

It is no wonder then that the company has put significant efforts into updating its flagship product.

“The first thing clients will notice is a completely redesigned user interface that provides easier access to the critical functions of the software, transforming the whole user experience with responsive design and efficient workflows,” Brew said.

Delivering this transformation has been a focal point for the business for more than a year, according to Brew, with developers reviewing customer requests most commonly received from the support team, analysing how users work with the array of Micromine functionality, and modelling interface scenarios to optimise the presentation of key functions within the software.

“By providing easier access to these functions and a smart interface that responds contextually, Micromine 2021 anticipates and supports workflows in a genuinely intuitive way,” Brew said.

The Micromine update has more than a new look.

It also includes new tools for importing and working with as-drilled drill-hole data, Brew explains.

These provide faster and more intuitive control over underground ring drill and blast design – also a focus of the earlier Micromine 2020.5 update – enabling designs to quickly adapt to changes in the field, identifying drilling inefficiencies and improving design protocols.

“We are also introducing intuitive tools that mirror the terrain of a blast face and speed up the process of creating blast-hole patterns within the bounds of the dig block,” Brew said. “Users will be able to accommodate polygons/blast masters of varying shapes, reducing the need for manual adjustment.”

The new grade control capabilities in Micromine 2021 provide dynamic updating of grade control reports to enable faster design preparation and reserve evaluation, according to Brew. This can allow miners to explore variations in dig block configuration and evaluate the ramifications of design changes on the grade – a function bound to appeal to opex-focused companies mining complex orebodies.

An integrated scheduler, meanwhile, enables planners to build and visualise an optimised schedule through configurable templates, scripting capabilities and scenarios built from real-world constraints, Brew said.

While the new and intuitive interface is likely to capture the immediate attention of users, MICROMINE has evidently not scrimped on updated and upgraded features.

Getting to the core

With the release of Pitram 4.17 earlier this year, there were improvements to the Materials Movement and Shift Planner modules, but Pitram 5, to be released later this year, goes above and beyond that.

“Stockpile management is now part of your end-to-end process and not managed as isolated assets within Pitram,” Brew says of Pitram 5. Geologists can work with data up- and down-stream to manage and react to material mismatches. Such data validation and accuracy is key to the value proposition Pitram drives in MICROMINE’s global implementations, according to Brew.

“Pitram is at the core of any mining operations ecosystem,” he said. “Our ability to accurately track Last Source, Destination Moved, Quantity and Grade as well as set individual depletion models across the various stockpiles across the mine, makes it a more flexible offering while maintaining data integrity.”

This near real-time tracking ability has previously failed on occasion from connectivity issues.

Not anymore.

“Pitram 5 is a huge leap forward in how we deploy our solution from a connectivity point of view,” Brew said. “Many of the mines we work with have limited or varying degrees of underground Wi-Fi and communications available. Our Peer to Peer solution bridges the gap where communication back to the server is not available at the face, for example.”

The Peer to Peer software can be installed on light vehicles which move around the mine encountering heavy equipment and collecting data in areas of no network coverage before moving back to a Wi-Fi-enabled area to sync the data back to the main server and into the control room. This allows miners developing new areas of their operation to keep up the communications flow without the need to immediately install or expand a communication network.

Such a solution has been successfully deployed at several sites globally, with Independence Group’s Nova nickel operation, in Western Australia, being the company’s reference site.

“Additionally, we have driven more R&D in how we can better leverage our Pitram Restful Integration Service (PRIS) to communicate shift planning data back to the shift bosses and mine managers in near real time,” Brew said.

The free Pitram Connect application, downloadable from the Apple or Google Play store, will show users real-time shift data as well as give them the ability to make updates to the shift, such as equipment or location allocations.

“Our ability to deliver on short interval control is a common requirement we are measured against and providing this planner to key users underground unlocks considerable value for an operation,” Brew said.

Pitram 5’s machine-learning update in the 2021 release leverages the company’s learnings from earlier deployments at some Central Asia mines.

“Utilising the processes of computer vision and deep machine learning, on-board cameras are placed on loaders to track variables such as loading time, hauling time, dumping time and travelling empty time,” he said. “The video feed is processed on the Pitram vehicle computer edge device, with the extracted information then transferred to Pitram servers for processing.”

Reflecting on the product updates and more than six months of pandemic-affected upheaval, Brew concluded: “Our business is extremely fortunate to have powered on through the COVID-19 pandemic, and we’ve worked hard to maintain our renowned ability to work, support and deploy our solutions remotely.

“Diggers & Dealers is the pre-eminent event for the Australian region of our business, with representation from all our customers, so it represents a fantastic opportunity to show how we continue to drive value to our existing customer base as well as connect with new customers.”

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.

Lynas Corp says it has taken a significant step towards developing its new Kalgoorlie rare earths processing plant having awarded Metso Outotec with a contract to supply the plant’s rotary kiln system following a competitive tender process.

The 110 m long, 1,500 t kiln is the largest and longest lead time piece of equipment required for the plant’s operation, according to Lynas.

The contract for engineering and supply of the kiln is valued at around $15 million, including the discharge housing, combustion chamber and burner, motor control stations and delivery to Kalgoorlie.

The kiln will be manufactured by Metso Outotec to Lynas’ own design, which improves on the design of the four 60 m kilns currently in operation at the Lynas Malaysia plant, the company says. The new kiln will provide increased efficiency and reliability, it added.

Lynas CEO and Managing Director, Amanda Lacaze, said: “The kiln is the longest lead time item for our Kalgoorlie project and placing this order is an important milestone in the development of our new processing plant in Kalgoorlie. We are making good progress on the project, and we look forward to working with Metso Outotec on the engineering and supply of the kiln.”

Stephan Kirsch, President Minerals business area, Metso Outotec, said: “We are excited having been selected by Lynas as a key supplier for the development of its significant greenfield project in Western Australia. The Metso rotary kiln system forms an integral part for the processing of rare earths.”

Metso Outotec will commence work on the kiln immediately, with components to be manufactured in Australia as well as in European countries, Lynas said.

The plant will process concentrate from the Mt Weld mine (pictured), also in Western Australia’s Goldfields region, and provide an intermediate feed for further processing to produce neodymium and praseodymium, which are key elements used in high-tech consumer electronics and green energy technologies. Concentrate is currently exported to the Lynas rare earth processing facility in Malaysia.

Monadelphous Group has secured a number of contracts across Western Australia with BHP as part of a package of construction and maintenance agreements worth circa-A$110 million ($75 million).

The news comes on top of existing maintenance and other contracts the company has previously secured with the major mining company.

These include a contract at the BHP-owned Mining Area C iron ore mine site in the Pilbara, where Monadelphous will provide upgrades to existing conveyer equipment, and power switching and stackers. Work is expected to be completed in the September quarter of 2020.

The engineering firm has also won a contract for the provision of services associated with the demolition and rehabilitation of a number of end-of-life facilities at Nelson Point in Port Hedland. This contract is expected to commence in January 2020 and will be completed in the September quarter of 2020.

Monadelphous will also carry out a 12-month extension to its existing contract with BHP’s Nickel West division for the provision of maintenance, shutdowns and off-site repair services at the Kalgoorlie nickel smelter.

Lastly with BHP, the company has been awarded a contract with thyssenkrupp Industrial Solutions (Australia) for the construction of a reclaimer and two stackers at BHP’s South Flank project in the Pilbara. thyssenkrupp has previously said these will be the largest rail mounted stacker/reclaimers in the world, with a loading capacity of 20,000 t/h.

Monadelphous’ work is expected to be completed in the March quarter of 2021.

In Queensland, meanwhile, the ASX-listed company has secured a three-year contract for the provision of general mechanical and maintenance services as part of Incitec Pivot’s scheduled turnarounds for its Queensland manufacturing facilities, it said.

Chrysos Corp completes PhotonAssay hat-trick at MinAnalytical Lab

IoT, Mineral exploration, Mining services, Mining software, , , , , , , ,

Following on from the successful commissioning of its second PhotonAssay Max system earlier this year, Chrysos Corp says it has now completed commissioning of a third PhotonAssay Max system at the MinAnalytical laboratory in Kalgoorlie, Western Australia.

The Chrysos PhotonAssay solution provides rapid, accurate, safe and non-destructive ore grade analysis and, with the installation of this new system, MinAnalytical’s Kalgoorlie facility now has the security of double-redundancy and the capacity to service customers with fast turnaround on up to 100,000 samples per month, Chrysos said.

The technology, which was developed by CSIRO, slashes the time it takes to analyse a drilling sample from days to hours, according to Chrysos, and is an alternative to the traditional fire assay process. It represents a chemical-free approach to material analysis that gives accurate results in minutes and uses a larger sample size than fire assay, with reduced sample preparation.
A further benefit is that the new process enables the sample to be tested repeatedly if required – unlike fire assay, which involves the destruction of the sample, the company says.

Arriving in Kalgoorlie in late October, the new PhotonAssay Max was installed by Chrysos and its manufacturing partner, Nuctech, and completed site acceptance testing in mid-November, with final sign-off occurring earlier this month.

“With NATA (National Association of Testing Authorities) accreditation of the new system expected in 2020, and a fully-automated sample preparation solution from Scott Automation incorporated by May, MinAnalytical’s Kalgoorlie laboratory represents the cutting edge of gold analysis and reporting,” the company said.

Chrysos was formed in 2016 in partnership between CSIRO and RFC Ambrian for the purpose of commercialising the PhotonAssay technology. Ausdrill has invested in Chrysos and is assisting in commercialising the company’s technology. Ausdrill, through its subsidiary MinAnalytical, was the first company in the world to offer the technology to mining companies.
