The Copper Mark, the assurance framework to promote responsible practices and demonstrate the contribution of the copper, molybdenum, nickel and zinc industries to the United Nations Sustainable Development Goals, has welcomed its first six non-copper participants seeking assurance against its framework.

The addition of these new sites follows the launch of the Copper Mark’s pilot implementation scheme for molybdenum, nickel and zinc producers last October. This expansion reflects the deepening collaboration between the Copper Mark, the International Molybdenum Association (IMOA), the Nickel Institute (NI) and the International Zinc Association (IZA) to promote sustainable and responsible production and sourcing practices within and across these critical transition mineral supply chains, it said.

These sites include:

  • Boliden Mineral AB – Kokkola (copper and zinc);
  • Boliden Mineral AB – Harjavalta (nickel);
  • Freeport-McMoRan Inc – Climax (molybdenum);
  • Freeport-McMoRan Inc – Henderson (molybdenum);
  • Molymet – Molymet Belgium NV (molybdenum); and
  • Molymet – Complejo IndustrialMolynor S.A. (molybdenum).

The pilot scheme will run to July 2023 and includes the independent third-party site assessment of the participating sites against the Copper Mark Responsible Production Criteria, the Risk Readiness Assessment. The site may receive the Molybdenum Mark, Nickel Mark and/or Zinc Mark if the independent assessment confirms that all criteria are fully or partially met. A full launch for producers of molybdenum, nickel, and zinc is planned for later in 2023.

The six new sites join the Copper Mark in addition to 16 existing copper-producing participants that also produce at least one of the additional metals. This shows the strong overlap between the producers of copper, molybdenum, nickel and zinc and the efficiencies gained through the multi-metal partnership, according to The Copper Mark.

Michèle Brülhart, Executive Director of the Copper Mark, said: “We are excited to be welcoming the first six molybdenum, nickel and zinc sites to participate in our assurance framework. It is vital that these resources, critical for supporting the low-carbon global transition, are produced and sourced in ways that meet increasing government and end-user demands for responsible business. Our collaboration with IMOA, NI, and IZA will help to further increase the percentage of responsibly produced copper, nickel, molybdenum, and zinc available to society.”

Eva Model, Secretary-General of IMOA, said: “We are delighted to see such a positive response to the Molybdenum Mark pilot from our IMOA members. We are proud that our collaboration with Copper Mark on the Molybdenum Mark will help our members increase the percentage of responsibly sourced molybdenum available in society, as well as enable them to meet market demands and increasing regulatory requirements relating to responsible sourcing.”

Andrew Green, Executive Director of IZA, said: “We celebrate these first six participants for representing the industry’s commitment to providing independent, transparent, and credible assurance for all stakeholders. This collaborative milestone recognizes that we all share accountability for enabling responsible business and sustainable development.”

Hudson Bates, President of NI, said: “We are pleased with the steady progress of the pilot scheme and that the Copper Mark framework is being adopted by molybdenum, nickel and zinc producers. The Nickel Institute is delighted to have been part of the development of the Nickel Mark. It is a valuable tool for the nickel value chain and other stakeholders to ensure that nickel produced sustainably can play its vital role in the energy transition and value chain initiatives promoting responsibility.”

ZERO Automotive has delivered what it refers to as an ultra-safe ZED70 Ti battery-electric converted utility vehicle, using LTO battery technology that does not suffer from thermal runaway, to Independence Group’s Nova nickel-copper-cobalt operation in Western Australia.

This is the second convered vehicle, and the first dual cab, for Barminco, the contractor at Nova.

Like the first delivery, this conversion also allows for ultra-fast charging and maintains the highest torque rating for a mining-spec battery-electric vehicle by a factor of one-and-a-half times, the company says. Site integration activities with charging infrastructure and data capture will be the focus in the coming months, with the installation of the Geotab GO9 telematic device allowing for vehicle monitoring and tracking.

This is the third vehicle delivered with METS Ignited support previously awarded to ZERO Automotive. It also forms part of the trials being undertaken by Barminco in its role as lead of the Electric Mine Consortium light and auxiliary vehicle working group, of which ZERO Automotive is also a participant.

The next conversion for Barminco will be its upgraded production platform, which will provide available torque of 267% greater than its closest competitor, and allows for faster charging, ZERO Automotive says.

Canada Nickel progresses carbon capture and storage test work for Crawford

Canada Nickel Company Inc says the latest test work on material from its Crawford project, in Ontario, Canada, supports the incorporation of carbon capture and storage into the develoment.

The company has devised an In-Process Tailings (IPT) Carbonation process, which, it says, is a novel method for accelerated carbon capture and storage that it believes has transformative potential.

The latest test work conducted at Kingston Process Metallurgy (KPM) confirmed that existing process streams can be used for IPT Carbonation, which the company believes should allow it to be timely and cost effectively engineered and incorporated into the project flowsheet.

Crawford is hosted in ultramafic rock, which naturally absorbs and sequesters CO2, according to the company, with the potential to actively capture and sequester carbon being a key consideration in Canada Nickel’s acquisition of the 42 sq.km of target ultramafic rocks in the Timmins area.

Canada Nickel has developed an active process that uses tailings as generated in the milling process and injects a concentrated source of CO2 for a brief period of time. This process, IPT Carbonation, fixes CO2 geologically while the tailings are still in the processing circuit, rather than after they have been finally deposited.

The company believes that, given its relative simplicity, this process could be scaled up with availability of concentrated (rather than atmospheric) sources of CO2, with the CO2 potentially delivered by downstream processing of Crawford concentrates, a wide range of industrial processing activities, green hydrogen production, or carbon capture facilities.

Canada Nickel said: “The process demonstrates the potential to produce NetZero Nickel™ and NetZero Cobalt™ for the electric vehicle industry, NetZero Iron™ and chromium for the stainless steel industry and generate substantial carbon credits during the process. The company believes that the need for a concentrated source of CO2 for this process and the substantial CO2 capture and storage capacity potential of its ultramafic land position could form the basis for an entire Zero Carbon Industrial Cluster in the Timmins-Cochrane region.”

The latest results from further lab-scale testing at KPM confirmed that a blend of tailings expected to be produced by Crawford and thickened to an expected operating tailings density could be successfully carbonated with the IPT Carbonation process, the company said. This is a significant result to demonstrate the process at higher solids densities as the pulp density and the tailings residence time will be a key driver of the process capital and operating costs, it explained.

The testing also attempted to understand what ultimate carbon capture potential is possible and the test resulted in 37 t of CO2 captured per tonne of nickel – 34 t of that amount was captured within 25 hours. The 37 t figure is believed to represent a potential maximum and there is no certainty that such amount could be achieved in commercial operation, the company said.

As a result of these results, the integrated feasibility study for the project is expected to be delivered in the June quarter of 2023. This delay, the company says, has no impact on the overall timeline to production, with Canada Nickel continuing to target receipt of permits by mid-2025 with construction to follow.

Mark Selby, Chair and CEO of Canada Nickel, said: “We believe the Crawford project has the potential to be a case study in how critical minerals are developed in Ontario and Canada. Crawford is poised to support the energy transition through the large-scale production of critical minerals, including nickel and cobalt, and to become the sole North American producer of chromium, while also supporting the country’s climate objectives through large-scale carbon capture and storage.”

The company believes the successful incorporation of IPT Carbonation could also potentially allow a portion of its project capital expenditures to become eligible for the carbon capture and storage refundable investment tax credits of 37.5% to 60% from 2022-30 and 18.75% to 30% from 2031-40 announced in the 2022 federal budget documents in Canada.

Selby added: “We look forward to continuing our positive momentum in 2023 as we complete this integrated feasibility study for Crawford, continue to successfully advance the Crawford permitting process, work with our recently appointed financial advisors to advance its overall financing package and aggressively advance our recently acquired Texmont property with its potential for near-term production. We are also excited by our successful tests of the regional exploration potential at Reid, Deloro, Sothman and Reaume which, as they are hosted in the same mineralisation as Crawford, offer the same potential for integrated carbon capture and storage – setting the stage for a Zero Carbon Industrial Cluster in the Timmins-Cochrane region.”

Metso Outotec says it has been awarded an order for the supply of key minerals processing technologies to OZ Minerals’ West Musgrave copper-nickel project in Western Australia.

The OEM’s scope of delivery includes an MP1250™ cone crusher, as well as Planet Positive classified flotation units and high-rate thickeners.

The TankCell® e630 flotation units (pictured) are the most proven large-scale cells in the 600 cu.m-plus category and come with the largest installed base of operating cells in the world, according to Metso Outotec.

Metso Outotec’s high-rate thickeners, meanwhile, were selected for their state-of-the-art technology and based on references from similar process plants, it said. Laboratory test work was conducted by Metso Outotec to aid thickener selection.

Kai Rönnberg, Vice President, Minerals Sales – Asia Pacific at Metso Outotec, said: “We are very excited to work on the West Musgrave project with OZ Minerals. We were able to align with the project’s key value drivers at an early stage and provide expert technical support.

“OZ Minerals has selected leading-class Planet Positive process equipment for their nickel and copper production process, and they will also be able to benefit from our extensive aftermarket capabilities and footprint in Western Australia.”

In September, the OZ Minerals Board greenlit the build of the West Musgrave copper-nickel project. The feasibility study the board signed off on detailed a 13.5 Mt/y operation with average production of circa-28,000 t/y of nickel and circa-35,000 t/y of copper over a 24-year operating life.

JP Morgan-backed financing paves way for further MineSense growth

MineSense Technologies Ltd says it has closed a $42 million Series E financing led by J.P. Morgan Asset Management’s Sustainable Growth Equity team that, it says, will allow it to accelerate the commercial deployment of its solutions to drive further growth and profitability.

The funding round includes participation from new investor Evok Innovations, a climate technology and sustainability venture fund, and existing investors including Prelude Ventures, BDC Industrial Innovation Venture Fund, Cycle Capital and Chrysalix Venture Capital.

MineSense has been pioneering data-driven solutions that improve ore grade control, operational profitability and carbon intensity across the metals mining industry. It is doing this through a combination of its ShovelSense® and BeltSense® hardware, a digital platform and geoscientific insight that goes beyond purely grade-based orebody information.

ShovelSense provides precise ore/waste definition and unlocks unique, previously inaccessible data sets at the mine’s extraction face, according to the company. This real-time data enables removal of waste from ore and recovers valuable ore from waste by making smart routing decisions that also reduces the amount of waste processed, production of tailings, and energy, water, and reagent consumption. Metal recovery is increased materially, with production from operating mines increasing by 5-25% on existing infrastructure, according to the company.

The company has initially been focused on copper, with those mining companies that have signed up to use its solutions looking to maximise ore recovery, minimise dilution and enhance operational sustainability.

MineSense says it has tripled revenue over the last year, and was recently recognised as one of the fastest growing companies in North America by Deloitte.

It currently currently serves mines across North and South America, with notable deployments in British Columbia (Teck’s Highland Valley Copper, Copper Mountain Mining’s operation and Taseko Mines’ Gibraltar operation), Chile (Carmen de Andacollo) and Peru (Antamina).

The fundraising will allow the company to expand its coverage globally and extend into other critical metals such as nickel, cobalt, zinc and iron, it said.

Jeff More, CEO of MineSense, said: “We are pleased to partner with J.P. Morgan Sustainable Growth Equity and Evok to scale our ore grade data mining solutions. This funding and strategic support will allow us to continue executing on our strategy of delivering profit enhancement, operational efficiency, and carbon intensity reduction to critical mining operations.”

Draslovka about to move into glycine leaching mining demonstration phase

Czech Republic-based Draslovka Holding is heading into a busy 12-month period where its glycine leaching technology will be showcased at numerous mining projects across the globe, the company told IM on the side lines of the Resourcing Tomorrow conference, in London, this week.

According to Ivor Bryan, Director of Mining Innovation at Draslovka Mining Solutions and the former MD of Mining & Process Solutions (MPS), the entity responsible for the development of the GlyCat™ and GlyLeach™ technologies, the company is embarking on around 10 projects in the mining space, which will prove up the 3,500 hours of testing that has been conducted at MPS’ facilities in Perth, Western Australia.

MPS was acquired by Draslovka, a major sodium cyanide producer in 2022, with the aim of the transaction being to grow and develop the glycine leaching business.

Gold leach testing via GlyCat has been the major area of focus over the last decade. The process was invented to reduce cyanide consumption while maintaining gold recovery for gold ores from deposits containing nuisance copper. It has been designed to enhance the dissolution of gold and copper in gold/copper ores where glycine is used as a catalyst with cyanide in a cyanide-starved leaching environment. It doesn’t replace cyanide, but, in fact, enhances its leaching capabilities by dealing with the high-cyanide consuming copper within these gold-copper orebodies.

Yet, the company is also now starting to make inroads into the base metal space through GlyLeach, with nickel and cobalt two specific areas of interest. The technology is able to leach the targeted metals with enhanced selectivity compared with conventional methods. It will solubilise copper, nickel, cobalt and zinc, while gangue minerals such as iron, manganese, silicates and carbonates remain in the leach residue, Draslovka says.

This is allowing the company to promote that it can reduce the capital expenditure associated with processing these metals by removing the need for smelting, or in the case of tailings deposits, helping recover metal from assets previously written off as ‘waste’.

While the technology could have applications at run of mine operations, Bryan and his colleague Jackson Briggs, Corporate Development Manager of Draslovka, believe the most immediate opportunity is in tailings where the application of glycine leaching on ‘waste’ material could recover valuable metals while reducing the potential liabilities associated with such storage facilities.

Of the 10 or so projects the company has ahead of it, one is situated in Western Australia where the company is looking to recover nickel and cobalt metals from a tailings deposit of a major mining company.

Another project – much closer to fruition – is in Chile and involves leaching a carbonate-hosted copper oxide deposit containing some 600 t of material.

In both cases, the company is looking to demonstrate that it can recover valuable metals at high recovery rates, with low impact – namely rationalising reagent and water use and, in the case of nickel-cobalt, removing smelting from the equation.

This, according to Draslovka CEO, Pavel Bruzek, is a “win-win” for mining companies and their stakeholders, benefitting both the balance sheet and the operational environmental footprint.

“While we are a major sodium cyanide producer, when we saw the potential of MPS’ glycine leaching technology and the increase in metallurgical complexity of orebodies looking to be exploited, it made perfect sense to work with and promote this technology,” he told IM. “It is the responsible thing to do for the industry.”

Glencore has signed a three-year contract extension with Wallis Drilling to retain the drilling company’s services at Murrin Murrin in Western Australia’s Goldfields region, which will extend Wallis’ long-standing relationship at the Glencore-owned operation to over a quarter of a century, the service provider says.

Wallis Drilling is a local Western Australian business, founded in 1965 by Marty and Jamie Wallis, which has grown to over 300 employees, but remains a family run business today.

Wallis has provided services to Glencore’s Murrin Murrin operation for 24 years and the contract extension, running through to September 2025, will see Wallis Drilling continue to provide RC grade control and blasthole drilling at Murrin Murrin.

Murrin Murrin is a nickel-cobalt mining and processing operation between Leonora and Laverton in the north-eastern Goldfields region of Western Australia and currently provides work for over 1,000 employees and contractors.

Wallis Drilling Manager, Wayne Waters, oversees the Murrin Murrin contract, with his role previously being occupied by Grant Wallis who is now the Chief Operating Officer of the business.

Waters said: “Murrin Murrin, like Wallis, understands the importance of establishing and nurturing long-term relationships to create stability, which has been exemplified by the latest contract extension.

“This business certainty is beneficial to Wallis, but it also gives us the capacity to plan for the long-term on site at Murrin Murrin and deliver the best operational outcomes.”

Grant Wallis said: “Our work at Murrin Murrin has helped us grow from a small family business to one of Australia’s largest privately-owned minerals drilling companies, while still remaining true to our local WA roots.”

Nic Fenner, Head of Mining Technical Services at Murrin Murrin, said: “We are very proud to help grow local Western Australia businesses, like Wallis Drilling, and help be a part in their success stories.

“The strong relationship between Murrin Murrin Operations and Wallis has been underpinned by our shared values and culture. Murrin Murrin and Wallis both have many long serving employees with some even being the second generation in their family to work at Murrin Murrin.”
