Deliberate electrification of the Cosmos underground nickel mine in Western Australia had no bearing on proprietor IGO’s resolution earlier this 12 months to shelve redevelopment resulting from low metallic costs and undertaking value escalation, The Electrical Mine 2024 heard this week.
Appearing COO of the diversified Australian miner, Chris Carr, stated on the convention in Perth a examine on the financial feasibility of switching from diesel gear to battery-electric that ‘introduced a compelling case to us’ for electrification highlighted present challenges and alternatives within the business’s push to transition to new era cell gear.
In parallel with the electrification examine by mining contractor Perenti and engineering main ABB, IGO accomplished a undertaking evaluation that lower Cosmos’ anticipated mine life and pushed up capital and working prices. Decrease nickel costs have negatively impacted most Western Australian sulphide nickel mines.
IGO put Cosmos into care and upkeep firstly of 2024. “Electrification was not a consider that call,” Carr stated on the The Electrical Mine 2024, hosted by Worldwide Mining Occasions. “However electrification shall be thought-about in any future Cosmos operation.”
A whitepaper summarising the examine outcomes was posted this week by IGO. ‘Making electrified underground mining a actuality: Classes from the Cosmos Electrification Research’ concluded changing diesel underground mining autos with a battery-electric fleet was now technically possible and can more and more be a key technological enabler for mining corporations to attain their decarbonisation targets.”
Perenti and ABB stated a mix of precise and projected battery-electric automobile value and efficiency information indicated BEV fleet obtainable to the Australian market might match the productiveness of mature diesel gear.
Additionally they discovered estimated prices to affect Cosmos’ modest underground fleet was not prohibitive over the deliberate mine life, ‘even primarily based on conservative productiveness and price assumptions.’ IGO wasn’t going to acquire full advantages from optimised air flow and different infrastructure design resulting from sunk funding within the mine previous to its acquisition of the asset in 2022, Carr stated.
The examine recognized gaps in obtainable BEV working and upkeep direct and oblique value information as a result of formative stage of kit, battery, charging and help system growth relative to entrenched diesel fashions.
It additionally highlighted considerably longer supply occasions for battery-electric gear than diesel fashions. “We hope this isn’t prioritising diesel items to make more cash Carr stated. “That is slowing adoption.” Nevertheless, Carr stated on the convention none of this may cease the march of EVs into conventional diesel territory.
The enhancing value profile of EVs and the market pull created by business decarbonisation targets weren’t the one drivers.”In five-to-10 years we’ll all be electrical and be questioning what all of the fuss was about. The associated fee differential of an all-electric mine introduced a compelling case to us. We additionally consider the choice to affect ought to embody the protection case and the more durable to quantify however nonetheless actual advantages of the ESG case. The choice to affect needs to be made on the mixed foundation of security, ESG and economics. The economics is the toughest one proper now. However security should be sufficient by itself.”
Stricter requirements for airborne diesel particulate matter (DPM) emissions in Australia and elsewhere would ‘push electrification rather a lot more durable,’ Carr stated.
MasterMined Innovation CEO, Tony Sprague, instructed The Electrical Mine 2024 DPM, and particularly nano-DPM, was ‘the elephant within the room’ and the ‘actual driver of getting diesel out of the underground mine and to attain the electrical mine.’ Sprague, the previous Group Supervisor of Directional Research and Innovation with gold main Newcrest, stated fashionable underground mine gear diesel particulate filters regenerated carcinogenic nano-DPM in underground work environments.
“It might’t simply be measured…however we do comprehend it’s extra simply absorbed into the human physique, via the pores and skin, via the lungs, and it’s recirculated via the physique, via the blood, and it impacts the physique on a mobile stage. Actually we’re flying blind relating to the hazard of DPM and nano-DPM. There’s a new [emission] goal that’s coming from Secure Work Australia that isn’t distant. When it’s going to land we’re not too certain, but when it does land it’s going to be very problematic for the business.”
