ERM on executing the mining sector’s sustainability strategies

With sustainability close to the number one topic shaping the business landscape, the mining industry faces perhaps more scrutiny today than ever before. From stakeholder engagement to employee welfare and the emissions generated from using mined commodities, there is a spectrum of issues on which mining companies are judged. Not just by traditional critics such as NGOs, but increasingly by policymakers, investors and consumers themselves.

As a result, mining companies are seeking the advice of consultants that live and breathe environmental, social and governance (ESG) issues to adapt to this evolving backdrop (see the mining consultants focus in IM October 2021 for more on this).

In this regard, they don’t come much bigger than ERM, which calls itself the largest global pure play sustainability consultancy. With a remit that goes into strategic, operational and tactical challenges, the company’s services have been in serious demand of late.

Louise Pearce, ERM Global Mining Lead; Jonathan Molyneux, ERM Mining ESG Strategy Lead; Peter Rawlings, Low Carbon Economy Transition Lead; and Geraint Bowden, Regional Client Director – Mining, were happy to go into some detail about how the company is serving the industry across multiple disciplines.

In demand

According to the four, there is increasing demand for services from miners interested in energy/battery minerals (lithium, cobalt, nickel, copper, platinum, palladium and rhodium (PGMs)) on the back of rising numbers of new mines coming onto the scene, “shorter supply chains to customers”, the perceived need to secure domestic supply of these minerals, and requirements of “evidence of responsibly-produced certifications from industry organisations such as the Initiative for Responsible Mining Assurance (IRMA)”.

Such trends have been underwritten by a shift in both the requirements and considerations around the extraction of these minerals, according to Molyneux.

“In the last five to seven years, the main ESG incentives for change have come from access to capital (ie investor ESG preferences, especially in relation to catastrophic incidents),” he said.

“Over the last three years, we have seen a strong rise in expectations from downstream customers, particularly leading brands.”

Automotive original equipment manufacturers like BMW and Daimler are placing sustainability at the centre of their brands, according to ERM. Their initial focus has been on ‘net-zero’ driving/electrification – and they have made progress on this with several major electric car launches. They then shifted to examining the carbon emissions and ESG, or responsible practices, of tier-one and tier-two component manufacturers. The last step has been a full analysis of the ESG credentials of input materials right back to source, ie the mine.

“We see a shift from the historic lens of customers managing supply risk by sourcing from organisations which ‘do little/no harm’ (eg human rights compliance, catastrophic incident avoidance) to supply partners that can contribute to the ‘do net good’ or ‘create value for all stakeholders’ (ie communities, workforce, nature positive),” Pearce said.

Such a shift has resulted in more clients considering “circular thinking” in their operational strategy, as well as carrying out risk reviews and transformation projects focused on a company’s social or cultural heritage. Tied to this, these same companies have been evaluating their water use, biodiversity requirements and, of course, decarbonisation efforts.

It is the latter on which the steel raw materials companies predominantly have been looking for advice, according to ERM.

The focus has been on ‘green’ iron ore, low-carbon steel and ‘circular’ steel, according to Molyneux and Bowden, with ERM providing input on how companies in this supply chain can integrate sustainability into their strategy and operations.

On the thermal coal side, meanwhile, it is a very different type of ERM service in demand: mine retirements, closure/local/regional regeneration transitions and responsible disposals.

Delivering on decarbonisation

The mining industry decarbonisation targets have come thick and fast in the last 18-24 months, with the latest announcement from the International Council on Mining and Metals (ICMM) seeing all 28 mining and metals members sign up to a goal of net zero Scope 1 and 2 greenhouse gas (GHG) emissions by 2050 or sooner, in line with the ambitions of the Paris Agreement.

Many have gone further than Scope 1 (direct emissions from owned or controlled sources) and Scope 2 (indirect emissions from the generation of purchased electricity, steam, heating and cooling consumed by the reporting company) emissions, looking at including Scope 3 (all other indirect emissions that occur in a company’s value chain) targets.

Fortescue Metals Group, this month, announced what it said is an industry-leading target to achieve net zero Scope 3 emissions by 2040, for example.

These are essential goals – and ones that all interested parties are calling for – in order to deliver on the Paris Agreement, yet many miners are not yet in the position to deliver on them, according to Pearce, Molyneux, Rawlings and Bowden.

“Miners need to look at decarbonisation at a holistic level across their operations and value chain, and cannot just delegate the net zero requirements to individual assets,” Rawlings said. “The solutions needed require investment and are often at a scale well beyond individual assets/sites.”

Much of this decarbonisation effort mirrors other industries, with the use of alternative fuels for plant and equipment, accessing renewable electricity supplies, etc, they said.

Process-specific activities can present challenges and is where innovation is required.

“These hard to abate areas are where a lot of efforts are currently focused,” Rawlings said.

Tied into this discussion is the allowance and estimates made for carbon.

There has been anecdotal evidence of miners taking account of carbon in annual and technical reports – a recent standout example being OZ Minerals inclusion of a carbon price in determining the valuation of its Prominent Hill shaft expansion project in South Australia – but there is no current legislation in place.

“We are seeing a broad spectrum of price and sophistication (targeted audience, knowledge level), but it is an active board level discussion for most clients,” Bowden said on this subject. “Most clients view this as market-driven requirements as opposed to a voluntary disclosure.”

This has been driven, in part, from the recommendations of the Task Force on Climate-Related Financial Disclosures, which many miners – including all the majors – are aligning their reporting with.

Some clients are also looking into scenarios to work around carbon regimes such as the Carbon Border Adjustment Mechanism, which proposes a carbon-based levy on imports of specific products.

Having acquired several companies in recent months focused on the low carbon economy transition – such as E4tech, Element Energy and RCG – ERM feels best placed to provide the technical expertise and experience to deliver the sustainable energy solutions miners require to decarbonise their operations.

“With these companies, combined with ERM’s expertise, it means we can support clients on the decarbonisation journeys from the initial strategy and ambition development through to implementation and delivery of their roadmaps,” Rawlings said. “We can support clients from boots to boardroom as they assess decarbonisation options and technologies; help them understand the financial, policy and practical aspects linked to deployment of solutions; and access the financing necessary to support deployment.”

ESG dilemmas

There is more to this evolving backdrop than setting and meeting ambitious environmental goals, yet, in ERM’s experience, the advice provided by consultants – and requested by miners – has historically been focused on individual ESG domains.

“This has often been driven by their realisation that their (miner’s) in-house policies and standards require updating,” Pearce said.

Louise Pearce, ERM Global Mining Lead

A siloed or disaggregated approach to ESG strategy development often reduces risk, but rarely generates value for the enterprise at hand, according to Pearce.

“What we have learned is that in order for organisations to create value, they need to focus on value drivers for the corporation,” she said. “These value levers are typically influenced by an integrated suite of ESG dimensions. For example, this could be looking at carbon emissions, connected with water use and nature, connected with local socio-economic development.”

“Sustainability and ESG are about understanding the inter-relationships between our social, natural and economic environments over the longer term. It cannot be about addressing one topic at a time or responding to the loudest voices.”

This is where ERM’s ‘second-generation’ ESG advice, which is driven by data and opportunities to create value as well as manage risk, is fit for the task.

“We are also finding that, at its heart, the central issue to second-generation ESG performance delivery/improvement for our clients is not just the strategy, but a willingness of organisations to reflect on their core values, how these have driven their traditional approaches and decisions and how they will need to evolve these if they want to achieve a genuine brand and reputation for ESG and achieve impact on the value drivers they have selected,” she added.

Such thinking is proving definitive in ERM’s mining sector mergers and acquisition due diligence.

“We have multiple experiences where clients have asked us to carry out an ESG review of a target portfolio, only to find that there is too great a gap between the target’s ESG asset footprint to align them with the client’s standard – or, that the carbon, water, closure or tailings profile of the target carries a too high-risk profile,” Molyneux said.

This is presenting clients with a dilemma as they want to increase their exposure to certain minerals, but are, in some instances, finding M&A is a too high-risk route. At the same time, the lead time to find and develop their own new assets is longer than they would wish for building market share.

Such a market dynamic opens the door for juniors looking for assets early in their lifecycles, yet it places a high load on the management teams of these companies to think strategically about the ESG profile of the asset they are setting the foundations for to eventually appeal to a potential acquirer.

“This is, in itself, a dilemma because, typically, the cash scarcity at the junior stage leads management teams to focus on the immediate technical challenges, sometimes at the cost of also addressing the priority non-technical challenges,” Bowden said.

Those companies who can take a strategic view on the ESG requirements of the future – rooted in a deep understanding of how to deliver change on the ground – will be best placed in such a market, and ERM says it is on hand to provide the tools to develop such an appropriate approach.

Ivanhoe advances Platreef development studies after Moolmans completes sinking

Ivanhoe Mines has announced another milestone at the Platreef platinum group metals project in South Africa, with construction complete at the 996-m level station of Shaft 1.

The achievement, completed well ahead of the contractual schedule, according to Ivanhoe, positions the company to equip Platreef’s initial production shaft, if it chooses to proceed with phased development of the mine on the Northern Limb of South Africa’s Bushveld Complex.

Sinking was carried out by contractor Moolmans, with the project remaining ‘Fall-of-Ground’ incident free since shaft sinking operations began in July 2016, the company said. On top of this, in June 2020, Moolmans and the Platreef team achieved South Africa shaft sinking industry leader status in terms of safety performance, according to Ivanhoe, which owns 64% of the project through Ivanplats.

Ivanhoe’s Co-Chairmen, Robert Friedland and Yufeng “Miles” Sun, said: “Given the flurry of recent transactions in precious metals markets, we are actively exploring a number of options that can help us unlock Platreef’s extraordinary value for the benefit of all Ivanhoe stakeholders.

“After all, Platreef is among this planet’s largest precious metals deposits.”

Platreef now has a completed shaft within a few hundred metres of the initial high-grade mining zone, according to Friedland and Sun.

“We have a mining licence, we have water and we have a team of highly-skilled employees,” they said. “The deposit has enormous quantities of palladium, platinum, rhodium, nickel and copper; and it has more ounces of gold than many leading gold mines.”

They concluded: “Given the current precious metals environment, I am confident that the pending studies will showcase the exceptional economics that one would expect from such a thick, high-grade and flat-lying deposit.”

Ivanhoe is updating the Platreef project’s 2017 definitive feasibility study (DFS) to account for development schedule advancement since 2017 when the DFS was completed, as well as updated costs and refreshed metal prices and foreign exchange assumptions.

The DFS for Platreef covered the first phase of production at an initial mining rate of 4 Mt/y, estimating Platreef’s initial average annual production rate would be 476,000 oz of platinum, palladium, rhodium and gold, plus 21 MIb (9,525 t) of nickel and 13 MIb (5,897 t) of copper.

Concurrently, Ivanhoe is finalising a preliminary economic assessment for the phased development production plan for Platreef. The plan targets significantly lower initial capital to accelerate first production by using Shaft 1 as the mine’s initial production shaft, followed by expansions to the production rate as outlined in the 2017 DFS, Ivanhoe said.

“The re-evaluation is being done in parallel with the ongoing mine development work to access the thick, high-grade, flat-lying Flatreef deposit that was discovered in 2010 and outlined in the Platreef 2017 feasibility study,” it said.

The new auxiliary winder for the 7.25 m diameter Shaft 1, which is scheduled to be delivered to Platreef later this year, will be used to assist in equipping the shaft; and thereafter for logistics, shaft examination and auxiliary functions. The auxiliary winder will provide a second means of ingress and egress from the shaft after removal of the stage winder.

Shaft 1 is around 350 m away from a high-grade area of the Flatreef orebody, planned for bulk-scale, mechanised mining.

Ivanhoe looks to align Platreef mine advance with palladium, rhodium price run

Ivanhoe Mines says it is fast-tracking a feasibility study on a smaller-scale, early-stage development plan at its Platreef palladium, platinum, nickel, copper, gold and rhodium project, in the Bushveld Complex of South Africa.

The move comes as spot prices of palladium and rhodium – two key metals contained in the Platreef ore – have soared in recent months. This has propelled Platreef’s ‘metals-price basket’ to a new, all-time high, Ivanhoe said.

Palladium prices surpassed a record $2,100/oz recently as stricter air-quality rules continue to boost demand for the metal used in vehicle pollution-control devices, while the price of rhodium has surged 32% already this month, attaining a price of more than $8,200/oz – the highest price since it hit more than $10,000/oz in 2008.

Ivanhoe’s plan would accelerate the mine’s first production by using Shaft 1 as the mine’s initial production shaft, followed by expansions to the production rate outlined in the project’s 2017 definitive feasibility study (DFS), it said. Ivanhoe’s smaller-scale mine design would also be optimised to target the highest-grade areas of the mineral resource in close vicinity to Shaft 1.

Platreef’s Shaft 1 currently is at a depth of 957 m below surface. It is scheduled to be completed to a final depth of around 1,000 m by the end of July. Work on Shaft 1’s 950-m-level station (pictured) – the shaft’s third and final station – is expected to be completed in March 2020.

Shaft 1 was previously expected to become the primary ventilation shaft during the project’s initial 4 Mt/y production case, with Shaft 2, around 100 m northeast of Shaft 1, providing primary access to the mining zones.

Platreef has an estimated 26.8 Moz of palladium in indicated resources, and an additional 43 Moz in inferred resources. This is in addition to an estimated 1.8 Moz of rhodium in indicated resources and an additional 3.1 Moz in inferred resources. Both of these are at a 2 g/t 3PE+gold cutoff.

In July 2017, Ivanhoe, which indirectly owns 64% of the Platreef project through its subsidiary, Ivanplats, issued an independent DFS for Platreef covering the first phase of production at an initial mining rate of 4 Mt/y. The DFS estimated Platreef’s initial average annual production rate would be 476,000 oz of platinum, palladium, rhodium and gold, plus 21 MIb (9,525 t) of nickel and 13 MIb (5,897 t) of copper.

Pre-sink of Shaft 2 at Ivanhoe’s Platreef underground project months away

In a review of exploration and development activities in 2018, Ivanhoe Mines has gone into some detail on developments at Shaft 2 at the Platreef PGM-nickel-copper-gold project on the northern limb of South Africa’s Bushveld Complex.

This follows a project update issued just after the Mining Indaba event in February.

Shaft 1, expected to reach its final depth of 982 m below surface in early 2020, will ultimately become the primary ventilation shaft during the project’s initial 4 Mt/y production case, but Shaft 2, around 100 m northeast of Shaft 1, will provide primary access to the mining zones.

Ivanhoe said Shaft 2 will have an internal diameter of 10 m, will be lined with concrete and sunk to a planned, final depth of more than 1,104 m below surface.

It will be equipped with two 40-t rock-hoisting skips capable of hoisting a total of 6 Mt/y of ore – the single largest hoisting capacity at any mine in Africa. The headgear for the permanent hoisting facility was designed by South Africa-based Murray & Roberts Cementation.

Ivanhoe said nine blasts were successfully completed in 2018 enabling the excavation of Shaft 2’s box cut to a depth of approximately 29 m below surface and the construction of the concrete hitch (shaft collar foundation) for the 103-m-tall concrete headgear (preparations pictured here) that will house the shaft’s permanent hoisting facilities and support the shaft collar.

Excavation of the box cut and construction of the hitch foundation is expected to be completed in the June quarter, enabling the beginning of the pre-sink, that will extend 84 m below surface, it said.

In July 2017, Ivanhoe, which indirectly owns 64% of the Platreef project through its subsidiary, Ivanplats, issued an independent, definitive feasibility study (DFS) for Platreef covering the first phase of production at an initial mining rate of 4 Mt/y. The DFS estimated Platreef’s initial, average annual production rate would be 476,000 oz of platinum, palladium, rhodium and gold, plus 21 MIb (9,525 t) of nickel and 13 MIb (5,897 t) of copper.

Eurasia and Uralmetmash agree on West Kytlim PGM-gold mining contract

Eurasia Mining has signed a mining contract for the 2019 season at its West Kytlim platinum, palladium, rhodium, iridium and gold mine in the Ural mountains of Russia.

Kosvinsky Kamen (KK), Eurasia’s subsidiary, and Uralmetmash (formerly Techstroy) have signed a pact that will see the latter carry out mining of platinum group metals and gold at West Kytlim.
Mining at West Kytlim is seasonal as the alluvial process relies heavily on running water. Work normally commences as the snow melts on site in late March or early April and proceeds until November.

The directors of Techstroy, the contractor employed at the West Kytlim mine for the 2018 season which achieved production well in excess of target (a total of 165 kg raw platinum against a targeted 100 kg), registered a new company, Uralmetmash, as a special purpose vehicle to focus on the West Kytlim.

Eurasia said the roles and responsibilities of each of the parties shall remain largely as before, with Uralmetmash responsible for pit development, mining, ore trucking, washing and disintegration, and KK responsible for concentrate upgrade, shipment of mine product and distribution of metal sales revenues.

The London-listed mining company said Uralmetmash intended to move on site immediately to prepare for mining, to include stripping of overburden and stockpiling of ore in preparation for washing, which can commence once the seasonal thaw is underway. The thaw can be expected sometime in April 2019.

The work will continue initially at the Kluchiki area, where work ended on schedule in November.

As part of the deal with Uralmetmash, the platinum revenues will be split on a 65%/35% basis, in favour of the contractor.

In the meantime, the refinery contract between KK and the Urals precious metal refinery has also been renegotiated to include an extra percent payment on the LME platinum prices (now at 98% LME, from 97% in 2018).

Eurasia Mining Executive Chairman, Christian Schaffalitzky, said: “We are pleased to be working again with the team that proved so effective during 2018. They were a very efficient operator last year, with a zero accident record, and financially motivated to develop the asset in a sensible manner.

“Furthermore, we are looking at ways to improve metal recoveries, based on the measured efficiency of the existing process flowsheet. We look forward to updating shareholders on progress and also our longer term development strategy for the West Kytlim reserves and resources before the season commences.”

Eurasia and KK personnel continue to work on an enlarged exploration programme for West Kytlim, to include the recently approved Flanks exploration licence and ensure adequate reserves are available for future mining seasons.

Work on analysis of the previous mining season’s performance has commenced and a sampling programme has been outlined for the tailings of the 2018 season. This information will be inputted to proposed modifications to the current circuit, with the possible addition of a jig to recover finer raw platinum fractions. The addition of a hopper to better control the loading of gravels to the front of the circuit, and achieve a more constant flow of material into the trommel, is also expected to improve recoveries during the 2019 season.
