Although occurring in late 2018, H-E Parts had deferred announcement to facilitate the completion of a new 100 t facility and the upgrading of equipment and machining capabilities that will allow Allgo to handle some of the largest mining, marine and oil & gas components required by the Western Australia market, it said.

Metal and mining companies collaborate with WEF on blockchain solutions

Seven leading mining and metals companies have partnered with the World Economic Forum (WEF) to experiment, design and deploy blockchain solutions that will accelerate responsible sourcing and sustainability practices, the WEF reports.

The Mining and Metals Blockchain Initiative will pool resources and cost, increase speed-to-market and improve industry-wide trust that cannot be achieved by acting individually, according to the forum.

“It aims to be a neutral enabler for the industry, addressing the lack of standardisation and improving efficiency,” WEF said, adding that the intention was to send out a signal of inclusivity and collaboration across the industry.

Among the seven companies represented in this initiative are Antofagasta Minerals, Eurasian Resources Group, Glencore, Tata Steel Limited, De Beers and Anglo American.

The group will look to develop joint proof-of-concepts for an inclusive blockchain platform, which, over time, could help the industry collectively increase “transparency, efficiency or improve reporting of carbon emissions”, it said.

The WEF explained: “In many cases, blockchain projects to support responsible sourcing have been bilateral. The result has been a fractured system that leaves behind parts of the ecosystem and lacks interoperability.”

The new initiative is owned and driven by the industry, for the industry, according to the WEF, with members examining issues related to governance, developing case studies and establishing a working group. Key areas of collaboration and development could include carbon emissions tracking and supply chain transparency.

“They will work to use blockchain technology to increase trust between upstream and downstream partners, to address the lack of industry standardisation and to track provenance, chain of custody and production methods,” it said.

Jörgen Sandström, Head of the Mining and Metals Industry at the WEF, said material value chains are undergoing profound change and disruption. “The industry needs to respond to the increasing demands of minerals and materials while responding to increasing demands by consumers, shareholders and regulators for a higher degree of sustainability and traceability of the products.”

The WEF has offered its platform and expertise to help industry leaders better understand the impact and potential of blockchain technology, it said. “It will provide guidance on governance issues related to the delivery of a neutral industry platform and the expansion of members.”

The move was welcomed by industry partners, including Ivan Arriagada, CEO of Antofagasta Minerals: “We hope this collaboration and pilot will give us practical examples of how blockchain can increase efficiency of the supply chain management and improve interoperability; address certain supply chain management risks such as transparency and consumer trust; and unlock opportunities including integration of key data such on environmental impact such carbon emissions.”

Benedikt Sobotka, CEO of Eurasian Resources Group, meanwhile, said the collaboration around blockchain technology would help industry efforts to enhance responsible sourcing. “By working together, our goal is to develop solutions that can be adopted across the industry and value chain,” he added.

Ivan Glasenberg, CEO of Glencore, said the development of this technology can facilitate industry reporting to improve compliance across the supply chain.

TV Narendran, CEO of Tata Steel, said: “As a responsible player in the mining and metals industry, we are committed to build a sustainable future.”

Jim Duffy, CEO of Tracr (representing Anglo American/De Beers), said the company looked forward to collaborating with the consortium as Tracr begins to roll-out its connected supply chain platform for the diamond industry. “Lessons learned creating Tracr are highly relevant to the sustainable sourcing of all mining and metals,” he added.

MIDEL ‘transforms’ safety at Glencore Mount Isa operation

MIDEL says it has helped improve safety at Glencore’s Mount Isa operations in north Queensland, Australia, following the introduction of its synthetic and biodegradable transformer fluid.

Operating since 1924, Mount Isa Mines is one of Australia’s largest industrial complexes extracting both copper and zinc-lead-silver, and contributing $1 billion to Queensland’s economy annually, according to MIDEL.

With over 3,000 workers operating in one of the world’s most expansive network of underground mines, as well as being Australia’s deepest underground copper mine at 1,900 m, safety at Mount Isa is paramount, MIDEL says. “With ore processed and smelted onsite too, the whole operation is power intensive and requires reliable, sustainable power infrastructure to maintain operations,” it added.

Glencore, as part of a risk mitigation program, identified mineral oil-filled transformers below ground at Mount Isa’s Enterprise mine as a potential fire risk, with the transformers flagged for further investigation.

Glencore invited MIDEL on-site to present options for reducing the risk posed by the transformers, and opted to retrofill the first transformer using MIDEL’s 7131 biodegradable, synthetic transformer fluid.

MIDEL 7131 has a high fire point (316˚C) and offers unrivalled fire safety benefits, according to the company, particularly for sites with enclosed spaces where smoke can be more deadly than the fire itself. “By retrofilling with a synthetic transformer fluid, the fire risk posed by the transformers was almost entirely eliminated,” MIDEL said.

Peter Ferguson, Electrical Superintendent at Glencore, said: “Despite MIDEL being more expensive than other transformer fluids, in the overall scheme of things, the difference was negligible particularly for such a vast improvement in safety.”

He added: “If we ever had to physically move the transformer this would be more costly and disruptive, so retrofilling with an oxygen-stable fluid gave us peace of mind.”

The benefits of switching to MIDEL’s synthetic ester include vastly reduced transformer fire risk, which means new units require no concrete blast walls, MIDEL said. This type of cost saving could extend into the millions of dollars, and transformers can be placed closer together, creating substantial substation space savings, too.

Additional operational benefits include improved moisture tolerance compared with that of mineral oil, which keeps the insulating paper in a better condition for longer and thus helps to extend transformer asset life. As MIDEL fluid is also fully oxygen stable, maintenance crews can handle it in exactly the same way as mineral oil, the company said.

Producers looking to improve their licence to operate can also leverage the environmental and sustainability benefits of synthetic ester, as it is fully biodegradable and non-toxic, MIDEL added.

 

Ausenco to lead First Cobalt refinery restart study

First Cobalt Corp, following a finance agreement with Glencore, has started to award key contracts to complete a 55 t/d feasibility study on the proposed expansion of its cobalt refinery.

Field work is expected to commence in September and will culminate in the delivery of a definitive feasibility study (DFS) in the March quarter, the company said.

Ausenco Engineering Canada will lead the preparation of a DFS for a refinery restart at 55 t/d with SGS carrying out advanced metallurgical test work on cobalt hydroxide and a specialty cobalt feed to be supplied by Glencore, Knight Piésold conducting tailings studies in support of the DFS, Story Environmental taking on the environmental and permitting aspects of the engineering studies and Glencore providing technical support throughout the study phase through its Sudbury-based affiliate, XPS – Expert Process Solutions.

In addition to the delivery of the DFS on a 55 t/d refinery restart, a prefeasibility study (PFS) on a 12 t/d interim operating scenario will also be conducted.

First Cobalt recently announced it had entered into a $5 million loan facility with Glencore to complete advanced engineering, metallurgical testing, field work and permitting associated with a recommissioning and expansion of the refinery. Upon completion of a positive DFS for the expansion, and subject to certain other terms and conditions, Glencore is prepared to advance an additional $40 million to recommission and expand the refinery, according to First Cobalt.

Trent Mell, First Cobalt President & CEO, said: “The First Cobalt Refinery is a permitted facility that is in excellent condition and has a recent operating history. Our strategy is to work with Glencore to expand the refinery to serve the growing needs of the North American electric vehicle market. To that end, we have partnered with a first-rate study team appropriate for the importance of the task at hand.”

Agua Rica-Alumbrera mine integration plan hits the right note in latest study

A plan to incorporate infrastructure from Glencore, Newmont Goldcorp and Yamana Gold’s jointly owned Alumbrera copper-gold operation, in Argentina, into the Agua Rica copper-gold project looks like paying off after a prefeasibility study (PFS) on the project highlighted an increase in annual output over the mine’s first 10 years and lower operating costs.

The three companies, in March, signed a definitive integration plan, which contemplated the development and operation of the Agua Rica project using the infrastructure and facilities of Minera Alumbrera, which saw open-pit mining conclude in 2018. This pact, they said, would realise important synergies, lowering initial capital required, and reducing the environmental footprint. As part of the deal, Agua Rica would be jointly owned by the three parties, with Yamana owning 56.25%, Glencore holding 25% and Newmont Goldcorp holding the remaining 18.75%.

Yamana said: “The integration plan generates significant synergies and lowers execution risk by bringing together the extensive mineral resource of Agua Rica with the existing infrastructure of Alumbrera to create a unique, high quality, and low risk brownfield project that the parties believe will bring significant value to shareholders and local communities and stakeholders.

“This unique and innovative project will serve to position Catamarca as a focal point for development in northwestern Argentina.”

Based on mineral reserves updated as at June 30, 2019, the PFS estimates a mine life of 28 years with average annual production over the first 10 years of around 533 MIb (241,765 t) of copper equivalent, including 107,000 oz of gold and contributions of molybdenum and silver. Average cash costs over this period were estimated at $1.29/Ib, with all-in sustaining costs coming in at $1.52/Ib.

Yamana said the initial capital cost estimate of $2.4 billion realises “significant synergies from using the infrastructure and facilities of Alumbrera”, with the project expected to generate an after-tax NPV (8% discount rate) of $1.935 billion based on a copper price of $3.00/Ib.

Opportunities to further improve the economics will be evaluated in a value-seeking study, scheduled for this year, and the full feasibility study, expected by 2020, Yamana said.

The PFS assumes a throughput rate of 110,000 t/d with scenarios considering a higher throughput rate to be evaluated in the value-seeking study and subsequent full feasibility study.

“Preliminary evaluations have indicated the potential for significant upside to the project economics from increases to throughput with existing mineral reserves to 115,000 t/d, which would improve NPV to over $145 million and require only a marginal increase to initial capital,” the company said.

The PFS for the integrated project considers the Agua Rica deposit to be mined via a conventional high tonnage truck and shovel open-pit operation. Average life of mine material moved is expected to be approximately 108 Mt/y, with ore feed of 40 Mt/y and average life of mine strip ratio of 1.66.

Ore extracted from the mine will be transported from the open pit by truck to the primary crusher area and then transported via a conventional conveyor to the existing Alumbrera processing plant. To route the overland conveyor system, approximately 5.2 km of tunnel development will be required. The conveyor extends 35 km to the Alumbrera process plant, where it will feed the existing stacker conveyor via a new transfer station.

Relatively modest modifications to the circuit are needed to process the Agua Rica ore in order to produce copper and by-products concentrate, according to Yamana, which will then be transported to the port for commercialisation. An in-situ blending strategy has been defined to manage the concentrate quality over certain years of the mine life, which will allow the project to achieve the desired targets, the company explained.

The high quality and well-preserved existing infrastructure of Alumbrera is fully used in the planned integration, Yamana said. Tailings storage facility, power supply, water supply, ancillary buildings, and logistical installations, among other infrastructure, are all included. “This significantly reduces the environmental footprint of the project,” Yamana said.

Given the level of progress achieved in the PFS, the parties have begun the process to prepare the Environmental Impact Assessment for the integrated project, as well as continuing engagement with local stakeholders and local communities, Yamana said.

First Cobalt edges closer to refinery restart after signing Glencore term sheet

First Cobalt Corp says it has agreed on a term sheet with Glencore that could see the First Cobalt Refinery in Ontario, Canada, recommissioned as early as next year.

The agreement outlines a non-dilutive, fully funded, phased approach to recommissioning the refinery remains subject to several conditions, First Cobalt said.

The First Cobalt Refinery is a hydrometallurgical cobalt refinery in the Canadian Cobalt Camp, a cluster that was historically mined for primarily silver, but is now being evaluated for cobalt. It is the only permitted primary cobalt refinery in North America, according to the company.

Phase 1 of this term sheet entails a $5 million loan from Glencore to support additional metallurgical testing, engineering, cost estimating, field work, and permitting associated with the recommissioning of the refinery. Within this amount is funding for a definitive feasibility study for a 55 t/d refinery expansion.

Phase 2 envisions commissioning the refinery at a feed rate of 12 t/d in 2020 to produce a battery-grade cobalt sulphate for prequalification for the electric vehicle supply chain, while Phase 3 involves an expansion of the refinery to a 55 t/d rate by 2021. This uses the current site infrastructure and buildings, and was detailed in a previous report by Ausenco, which estimated that First Cobalt could produce 5,000 t/y of contained cobalt in sulphate assuming cobalt hydroxide feed grading 30% cobalt.

The total capital investment under the three phases is estimated at around $45 million, with Phases 2 and 3 remaining subject to the findings of the studies undertaken during Phase 1, First Cobalt clarified.

Trent Mell, First Cobalt President & Chief Executive Officer, said: “Transitioning to cash flow as a North American refiner is our primary focus and today’s news demonstrates that we are moving closer to achieving that objective. Glencore has been supportive throughout the process and we look forward to working closely with their technical team on a successful execution.

“This partnership will help First Cobalt achieve its stated objective of providing ethically-sourced battery-grade cobalt for the North American electric vehicle market. An operating refinery in North America can benefit all North American cobalt projects, as it significantly reduces the capital cost of putting a new mine into production.”

The framework follows a memorandum of understanding signed by the companies back in May.

First Cobalt will also enter into a services agreement with XPS – Expert Process Solutions, a Sudbury-based metallurgical consulting, technology and testing facility affiliated with Glencore, in order to provide technical support to the First Cobalt team. A tendering process is nearing completion to designate lead third-party firms to oversee advanced metallurgical testing, the feasibility study and permitting, First Cobalt said.

Bis secures four-year contract extension at Glencore-owned Murrin Murrin mine

Bis says it has extended its haulage and site services contracts for Minara Resources at its Murrin Murrin nickel mine in Western Australia’s north-eastern Goldfields.

The multi-year extension will see Bis extend its longstanding partnership with Minara, wholly-owned by Glencore, where it has been delivering a range of services at Murrin Murrin since the operation began in 1998.

Bis’ services at Murrin Murrin include haulage and haul and road maintenance services, calcrete services, and bulk logistics services. The Murrin Murrin site also recently hosted Bis’ new innovative haul truck, Rexx, as part of its trials in working mines across Western Australia.

Bis Chief Operating Officer, Michael Porter, said: “We are proud to have been part of the Minara operations for over 20 years, working in collaboration with Minara to deliver safe and innovative solutions that add value to their operation. We look forward to continuing our successful relationship with our colleagues at Murrin Murrin.”

Innovators and disruptors heading to AIMEX 2019

Technological advancements, workforce changes, community collaborations and environmental challenges are just some of the concepts that will be discussed at Asia-Pacific’s International Mining Exhibition (AIMEX) 2019 edition, in August.

Focused on the future of Australia’s mining industry, AIMEX is the country’s largest and longest running mining exhibition and conference, according to organisers.

Speakers and key topics of the free-to-attend conference have been announced, with the line-up for the three-day event set to provide visitors with a “unique opportunity to hear from mining innovators and disruptors at the same venue where the technology is on show”, the organisers said.

Sponsored by Davey Bickford Enaex, the AIMEX conference has been developed with direct input and consultation from key mining personnel, industry associations as well as key mining companies.

On the opening day, a panel of speakers from across the mining spectrum will dissect the industry’s image and discuss ways that the mining sector and the community can work more collaboratively together in the future. Mach Energy’s Ngaire Baker, Mark Jacobs from Yancoal, Dr Kieren Moffat from the CSIRO and Anna Littleboy from the University of Queensland will lead the discussion.

Ngaire Baker, External Relations Manager for MACH Energy, said it is crucial the mining sector demonstrates the value it can offer communities, especially in regional and rural areas.

“I’ve worked and lived in some of Australia’s most remote mines and mining towns, combined with towns such as Orange, Parkes and Singleton, in New South Wales; I have experienced first-hand just how vital it is for the mining industry to look after these communities and to do our jobs to the best of our ability so that both parties reap the benefits,” Baker said.

“The mining industry can bring so many benefits to regional areas and to have the opportunity to discuss these very important issues with experts from all sides of the spectrum at the AIMEX conference is invaluable.

“I have been attending AIMEX since the mid ’90s and I make every effort to connect with suppliers and learn about new technologies that will benefit the operation I am working in. To be able to attend the conference as part of AIMEX is invaluable, we are all time poor and this conference is a key part of the three days of AIMEX, it provides me with a rare opportunity to hear from visionaries, engage with my peers and challenge the current mindset.”

A highlight of day two, organisers say, will be the panel discussion on how the mining community can reinvent its approach to talent acquisition and retention for today’s agile, digital, mobile, analytical, and technologically-driven workforce.

Mining Leaders Group Founder, Brett Cunningham, CEO of Weld Australia, Geoff Crittenden, and Jamie Frankcombe, Whitehaven Coal’s Chief Operating Officer, will lead the thought-provoking discussion that will exchange ideas and share current thinking to prepare for tomorrow’s demands in areas such as recruiting, educating schools, upskilling and diversity.

The organisers said: “Other highlights of the conference include Dr John Cronin’s presentation on using telepresence technologies for the safe deployment of wireless mesh networks and underground inspection robots in mines, cross-industry learnings from the oil & gas industry that define and mitigate HMI risk with technology and analytics, and the final day panel which looks at adapting to climate change, emissions and what does this look like for the mining sector?”

More than 6,000 mining industry professionals and over 500 exhibitors are expected to take over Sydney’s Showgrounds across three days from August 27-29 .

Embedded within the exhibition and conference, five of Australia’s biggest mining companies, Centennial Coal, Glencore, Mach Energy, Whitehaven Coal and Yancoal will for the first time, come together to create the AIMEX Mining Pavilion.

AIMEX Exhibition Director, Brandon Ward, said no other mining event gives you access to this volume of suppliers and this calibre of speakers for free.

“AIMEX is about pushing boundaries and challenging operations and business to innovate not just through technology but through workforce practices, social engagement and policy reform,” Ward said.

“This year’s AIMEX Conference is our most extensive yet which means mining professionals have a forum for open and transparent dialogue that will drive the sector forward.”

Attendance to AIMEX is free for both the exhibition and conference with registrations now open. For a full overview on the AIMEX Conference including session topics and speakers, plus a complete list of exhibitors, visit the event website aimex.com.au.

Two Crush It! Challenge finalists being guided by Glencore XPS team

Glencore’s XPS (Expert Process Solutions) is playing a role in Natural Resources Canada’s Crush It! Challenge by volunteering consulting services to two applicants recently named finalists in the competition.

XPS has much technical and operational expertise in the area of comminution and has been willing to impart its wisdom on the two teams.

The Crush It! Challenge was announced in October 2018 with the aim to realise an innovative breakthrough in the mining industry’s most energy-intensive and inefficient processes: crushing and grinding.

The primary objectives of the challenge are to fight climate change by creating innovative technologies that reduce energy consumption and pollution, increase competitiveness by developing world-leading clean technologies, and transform the mining cycle to establish a new “future in mining”.

Semi-finalists (up to 12) receive C$10,000 ($7,402) to help them pitch their ideas to the Challenge Jury, with up to six finalists being granted up to C$800,000 to build and test their clean technologies. The winner and innovator demonstrating the most superior energy breakthrough to crush and grind rocks is awarded a C$5 million prize to fully develop and roll out their solution.

On April 30, Natural Resources Canada announced the six finalists, which including two submissions that received consulting services from Glencore’s XPS.

Gillian Holcroft from the Canada Mining Innovation Council is representing a team in the finals for her Conjugate Anvil Hammer Mill (CAHM). “CAHM is a platform technology that has the potential to reduce energy consumption by 50% and replace several types of mills,” Glencore said. “Improved sustainability and lower costs could transform non-viable mineral development projects into new mines in Canada.”

Erin Bobicki of the University of Toronto is the project leader representing another finalist for her Microwave Pre-treatment and Ore Sorting technology. “This innovation combines microwave-assisted comminution and sorting to achieve energy savings of up to 70%,” Glencore said.

“A benefit of this innovation is that it is a scalable technology that can be easily integrated as a technology add-on for existing operations, therefore, it requires a small footprint as no additional infrastructure or utilities are required to support it. Given the sizeable energy savings, the innovation has the potential to transform non-viable mining projects into new mines.”

Now that the finalists have been announced, they are readying technical reports to showcase their clean-tech solutions submissions by the November 30, 2020, deadline. In March 2021, the final grand prize winner will be announced.

GMG publishes new short interval control guideline

The Global Mining Guidelines Group (GMG) says it has published the Guideline for Implementing Short Interval Control (SIC) in Underground Mining Operations.

SIC is a structured system in which data from mining processes are periodically reviewed and action is taken in response to them, GMG explained. “This guideline provides a roadmap to increase the speed and likelihood of success during SIC implementation while avoiding common pitfalls.”

Specifically, the publication presents a conceptual model of what SIC could look like that includes an operational framework, detailed workflows, and an outline of data enablement at various levels of maturity, according to GMG.

SIC has only recently begun to be used in underground mining, although it has a long history in the manufacturing industry.

GMG said: “One challenge in implementing SIC is tailoring it to the operation at hand because underground mining conditions can be unpredictable, but the guideline offers mining stakeholders a base of knowledge of how it can be applied.”

Greg Sandblom, Operation and Business Technology Lead at Sudbury Integrated Nickel Operations, a Glencore Company, says the guideline “can provide a valuable reference to mining companies during all phases of SIC deployments at existing mines or new mine projects”.

He continued: “It can effectively act as a checkpoint to validate that lessons learned and experience from leaders across the mining industry are applied to their implementations.”

Lisa Önnerlov, Development Engineer – Industrial Design at Boliden, said there was potential for the application of the guideline for those already using a SIC system.

“Even though we have been working with SIC for many years, we still have a lot to improve,” she said. “We face challenges like refining the overall coordination and to take advantage of new technological possibilities and make it useful in reality. We hope that this guideline will be a tool for both benchmarking and as a common reference in collaboration with other mining companies working with SIC.”

SIC has the potential to increase productivity and lower costs, according to GMG. As the practice becomes more common, it will, in turn, become increasingly accessible, according to Gordon Fellows, President of Fellows Mining and Digital Solutions.

“Achieving the greatest benefit from SIC comes from monitoring and controlling the shortest interval, but results are possible even at lower levels of maturity and at lower cost,” he said. “As technology evolves, it will make it simpler and less expensive to reach higher levels of maturity.”

One highlight of the process of developing the guideline, according to Liv Carroll, Senior Principal, Mining Transformation and Applied Intelligence at Accenture, has been the input from and cooperation between various stakeholders in the mining industry.

Carroll said there had been “effective collaboration between operators, service providers, consultants and technology specialists alongside the GMG team; our industry working as one for the benefit of all”.

She added: “In working together, we have drawn on a breadth of global and diverse experience to amalgamate leading practices into the guideline considering all levels of maturity and allowing for future evolution.”

Looking ahead, implementing SIC offers great potential for positive change in the industry because it facilitates better planning, quicker decisions, increased production, lower costs and creates a safer working environment, according to GMG.

GMG Chair, Michelle Ash, says: “I am very excited to see the publication of the SIC guideline because it is not only the culmination of a lot of work from many people, but also a fundamental building block for the transformation of our industry. I am looking forward to visiting mines post implementation and seeing the case studies that arise from their efforts.”
