Gold Fields plans to test the use of LNG to power haul trucks in a trial at its Tarkwa open-pit gold mine in Ghana, CEO Nick Holland told attendees of the IMARC Online event this week.

Speaking on a panel reviewing progress of the Innovation for Cleaner, Safer Vehicles (ICSV) initiative – a supply chain collaboration between the International Council on Mining and Metals (ICMM) and original equipment manufacturers (OEMs) – Holland said the trial would involve a mix of LNG and diesel fuel at the operation, and four trucks would initially be tested with the fuel combination in 2021.

Gold Fields later confirmed to IM that the trial would take place in the second half of 2021 and involve the use of Caterpillar’s dual-fuel LNG Dynamic Gas Blending (DGB) retrofit system on four of the mine’s Cat 785C 146 t payload dump trucks.

The DGB conversion kits, available on Cat 785C and 793D haul trucks, are a dual-fuel technology that enables miners to substitute diesel fuel with LNG, according to Cat. The use of LNG has been proven to reduce emissions by up to 30%, as well as lower costs by up to 30%, Cat says.

DGB vaporises liquid fuel into natural gas, then replaces diesel fuel with LNG when possible. On average, DGB replaces about 60-65% of diesel with LNG, according to Cat.

Tarkwa, which is 90% owned by Gold Fields, produced 519,000 oz of gold in 2019, 1% lower than the 525,000 oz produced in 2018. It employs Engineers & Planners Co Ltd as mining contractor.

While this trial will potentially lower the company’s carbon emissions – as will Gold Fields’ plan to fit “diesel filters” on all its machines underground in the next 12-18 months – Holland pointed to a much loftier long-term goal during the ICSV panel.

“The challenge to our teams and OEMs is to move away from diesel completely,” he said.

Such a move could see the company employ both battery-powered and hydrogen-powered solutions at its underground mines, he added.

The Innovation for Cleaner, Safer Vehicles (ICSV) initiative – a supply chain collaboration between the International Council on Mining and Metals (ICMM) and original equipment manufacturers (OEMs) – has made significant progress towards understanding what is needed to transform today’s fleet of mining vehicles into tomorrow’s new generation of cleaner, safer vehicles, members of its CEO Advisory Group announced today at IMARC Online.

The ambitions of the ICSV initiative are to introduce greenhouse gas emission-free surface mining vehicles by 2040, minimise the operational impact of diesel exhaust by 2025 and make vehicle collision avoidance technology available to mining companies by 2025.

Two years on from announcing these ambitions, eight new OEMs have joined the initiative, taking the number of participating OEMs to 19, the ICMM said. This includes 3MTech, Behault, Future Digital communications, MTU, Miller Technologies, Miller Technologies, Nerospec, Newtrax and Torsa, the ICMM confirmed to IM.

ICMM members, representing around 30% of the global metals market with over 650 assets, have undertaken assessments to establish a clearer view of the progress made at site level towards each ICSV ambition. These assessments indicate ICMM members are generally at early stages of maturity in the journey, and show what progress will look like for each ambition, the ICMM said.

“This significant representation of industry can speak with an aligned voice, on aligned objectives with OEMs and third-party technology providers,” it added. “In its first two years, the ICSV initiative has achieved the critical step of sending strong signals to OEMs and third-party technology providers on their requirements, and on what is needed to accelerate development and adoption of technology across the industry.”

The initiative is led by a CEO Advisory Group comprising each leader of BHP, Anglo American, Gold Fields, Caterpillar, Komatsu and Sandvik, several members of which spoke today at IMARC Online about the collaborative model.

Nick Holland, Chief Executive, Gold Fields (and Chair of the CEO Advisory Group), said there was a critical need to advance work on cleaner, safer vehicles in mining, which will have important health and safety benefits and contribute towards the pressing need of decarbonising the mining industry.

“It is recognised that there are measures we can implement now, but other, more impactful, interventions are reliant on technology pathways that are still evolving,” he said. “This will undoubtedly take time, but the industry’s collaboration with OEMs, through the ICMM, is critical as we look for these long-term, sustainable and integrated solutions.”

Mike Henry, Chief Executive, BHP, added: “Safer, cleaner mining equipment is important for our people and the world. No one party can tackle this on their own though. The ICSV initiative brings together equipment manufacturers and ICMM members to accelerate the innovations required to improve equipment safety and reduce emissions. This is a great example of the collaborative industry-level effort that can help bring about the scale and pace of change that is needed.”

Denise Johnson, Group President, Caterpillar, said the OEM was committed to helping customers operate safely and sustainably, with the ICSV initiative helping it collaborate even more closely with the mining industry in these important areas.

“Its progress to date has helped to form a shared understanding of where the industry is on its journey and demonstrates that by working together we can more quickly accelerate the pace of change,” she said of the initiative.

Tom Butler, CEO, ICMM, added: “Partnership and collaboration fuels long-term sustainable development, and is crucial to addressing some of the mining industry’s biggest sustainability challenges. Progress made on the ICSV initiative has been building the widespread confidence needed to accelerate the level of innovation investment required to scale up commercial solutions. The initiative will benefit the entire industry and is open to all OEMs who would like to join.”

ICMM has developed tools to support the industry, OEMs and third-party technology providers to meet the initiative’s ambitions, it said. These tools include an ICSV Knowledge Hub that, the ICMM says, facilitates knowledge sharing of industry innovations, provides technical and practical resources including case studies, standards, regulations and a technology and solutions database.

Additionally, a set of “maturity frameworks” that help to “map, motivate and measure” progress against the ambitions have been published, with the intention to stimulate conversations within companies that drive thinking, decision making and action, it added.

In 2021, ICMM’s company members will focus on integrating the initiative’s goals into their corporate planning processes, allocating internal resources and effectively leveraging external resources such as synergies with other industry initiatives and collaboration between member companies, the ICMM said.

Corrego do Feijão tailings dam collapse leads to rise in fatalities: ICMM

The International Council on Mining and Metals’ (ICMM) latest safety data report from its member companies showed that there were 287 occupational fatalities in 2019, a marked increase from the 50 recorded in 2018 and 51 recorded in 2017.

The occupational fatality rate (calculated per one million hours worked) shows an increase from 0.022 in 2018 to 0.118 in 2019, while the overall injury rate decreased from 3.41 in 2018 to 3.20 in 2019, according to the ICMM. Sixteen company members recorded no fatalities in 2019, an increase from 11 members in 2018, it said.

ICMM said its members − which includes 27 of the world’s leading mining and metals companies − share an “unwavering commitment” to improving health and safety performance, towards a goal of zero harm.

To support this commitment, ICMM compiles, analyses, and publishes the safety data provided annually by company members. The full report, Safety Data: Benchmarking progress of ICMM company members in 2019, is available here.

Of the 287 occupational fatalities recorded, 250 occurred as a result of the catastrophic collapse of a tailings dam at Vale’s Corrego do Feijão mine in Brumadinho on January 25, 2019.

After structural failure, the second highest cause of fatalities was mobile equipment and transportation, which accounted for eight fatalities in 2019, seven fewer than the 15 fatalities recorded in 2018.

Tom Butler, CEO of ICMM, said: “One fatality is one too many. In 2019, 287 people lost their lives while at work, which is as a stark reminder that while the mining and metals industry has come a long way in improving how it operates, there is still much more to do to safeguard lives, improve performance and demonstrate transparency.

“Trust in our industry’s ability to operate safely was rightly questioned following the tragic Brumadinho dam collapse early last year, which claimed the lives of 270 people – 250 workers and 20 community members.

“Our members are committed to taking action, and the imminent publication of the Global Tailings Standard, which has been developed through an independent review co-convened by the United National Environment Programme, Principles for Responsible Investment and ICMM, will be a vital step towards improving the safety and security of tailings facilities, and rebuilding public trust in the sector.

“Monitoring and reporting on occupational health and safety indictors is an important aspect of driving performance improvement. In 2019, the second highest cause of fatalities was from mobile mining equipment and transportation. ICMM’s members are committed to accelerating investment in vehicle safety through our Innovation for Cleaner, Safer Vehicles program – a collaboration between ICMM members and original equipment manufacturers.”

The report also examined incidents by country. Company member operations in Brazil had the highest fatality rate of 0.83, recording 252 fatalities from some 303.6 million hours worked. Operations in South Africa recorded 10 fatalities and Zambia six, where 392.9 and 46.8 million hours were worked, respectively.

ICMM began collating and publishing company members’ safety data in 2012 with the aim of encouraging information and knowledge-sharing among members, and catalysing learning across the industry, it said. This platform of information sharing and learning has continued to support members through the challenges arising from the COVID-19 pandemic where the health and safety of workers and local communities is paramount.
