Mining equipment: suppressing the fire risks

As mine workers continue to work long hours across consecutive shifts, heavy duty mining vehicles and machinery – for overground and underground operations – is often required to work 24/7 to meet tight schedules. Operating in the high-risk mining environment, with dust, extended use and prolonged vibration all raising risk of equipment overheating, heavy duty mining vehicles are susceptible to increased fire risk.

No wonder geopolitics were ranked second in EY’s -Top 10 business risks and opportunities for mining and metals in 2023. Indeed, without political stability the future of the industry is gloom. According to the BBC’s calculations, coups have been occurring at an average rate of two per year on the continent between 2000 and 2019. Recently, Mali’s president Ibrahim Boubacar Keïta was overthrown, followed a few months later by the dismissal of the transitional government.

A coup d’état took place in Burkina Faso on 30 September 2022, removing Interim President PaulHenri Sandaogo Damiba over his alleged inability to deal with the country’s Islamist insurgency.

The danger of such conflicts especially in countries relying heavily on minerals is enormous. It is difficult to carry out mineral exploration and processing in conflict areas.

And reduced exploration has a direct impact on the whole value chain of the mining industry. The net effects are diminishing earnings not only for the miners but also the countries involved. Africa cannot afford such misfortunes at this time especially when they can be avoided.

Roscan Gold signs royalty agreement for Roscan’s Kandiolé project

discoveries from the surface at Mankouke South and Central Mankouke. Roscan continues to strategically expand its drilling program and test the current key targets in West Mali, the most productive greenstone gold belts on the continent.

Aroyalty financing deal has been signed between Roscan Gold and Osisko Gold for the Roscan’s Kandiolé project in Mali.

The two inked a deal to raise C$10m ($7.42m) in gross proceeds. It will also see Osisko retain the option to purchase a second 1% NSR for an additional C$5m at any time on the Kandiolé project.

Osisko has already purchased a 1% net smelter return royalty for C$5m ($3.7m)

for upfront consideration. It will also retain the option to purchase a second 1% NSR for an additional C$5m at any time on the project. Roscan, however, will have the right to oblige Osisko to acquire the additional 1% NSR royalty in case the firm secures a long-term exploitation licence from the Malian Government on the 401.8km² Kandiolé property.

The Kandiole Project consists of exploration properties located in West Mali, hosting two high-grade gold

In a press statement, Roscan said: “Osisko has also been granted a right of first refusal (the “ROFR”) on future royalties and streams related to the property including in relation to the company’s outstanding buyback rights, should the company decide to sell those rights, and royalties on any future properties acquired or claimed by the company that are contiguous or complementary to the property.”

Roscan president and CEO Nana Sangmuah said: “We are very happy to welcome Osisko Gold Royalties, a leading royalty and streaming provider, as a strategic partner while we continue to unlock significant value on the very prospective Kandiolé project, which is strategically located between two of the largest producing gold mines in Africa.”

Caterpillar unveils first battery electric large mining truck

Caterpillar Inc, has unveiled its first battery electric large mining truck. The prototype 793 rigidframe dump truck performed its first live demonstration on a 4.3-mile course fully loaded.

The prototype truck was built at Caterpillar’s Tucson Proving Ground, located in Green Valley, Arizona. The construction and mining equipment manufacturing giant completed development of the electric truck with support from key mining customers participating in Caterpillar’s Early Learner program. Participants of the program with definitive electrification agreements included BHP, Freeport-McMoRan, Newmont Corporation, Rio Tinto and Teck Resources Limited.

During the demonstration, Caterpillar monitored over 1,100 data channels, gathering 110,000 data points per

second, to validate simulation and engineering modelling capabilities. The battery-electric truck clocked a top speed of 37.3 mph on its 4.3-mile test, similar to the diesel model. It travelled .62 miles up a 10% grade at 7 mph and .62 miles downhill at a 10% grade.

Cat further noted that on the downhill section the truck captured energy “that would normally be lost to heat”

and returned it to the battery. This is a process known as regenerative braking in which energy lost when applying the brakes or taking pressure off the accelerator pedal is captured and used to recharge the battery.

“Upon completing the entire run, the truck maintained enough battery energy to perform additional complete cycles. Our global team came together to develop this battery truck at an accelerated pace to help our customers meet their sustainability commitments. This demonstration is a significant milestone, and we are excited for these trucks to get to work at customers’ sites around the world in the near future,” said t Denise Johnson, Resource Industries Group President. 3

Aton granted force majeure compensation period

Aton Resources has been issued a six-month force majeure compensation period at the Abu Marawat Concession in the Eastern Desert of Egypt, under the provisions of the Abu Marawat Concession Agreement.

Interim CEO Tonno Vahk confirmed the report and said the compensation period will be added to the final exploration period of its current exploration license thus allowing completion of maiden mineral resource estimate (“MRE”) at the Rodruin deposit, as well as updating the existing Hamama West MRE.

“We are very pleased to announce that this extra time has been added to the term of the Abu Marawat exploration

licence, primarily to make up for time unavoidably lost during the Covid-19 pandemic. We wish to thank the Egyptian Mineral Resources Authority and the Ministry of Petroleum in Egypt for their continuous support and their assistance in making this happen,” he said.

“We will complete the diamond drilling at Rodruin within the next fortnight,

GHH Launches the New LF – 10 NEO Load Haul Dumber (LHD)

The LF-10 NEO has a z-link design with the maximum tipping height in its class, of 2.5 m, which is perfect for truck loading all 30 ton trucks in the market.

“The high break out forces, efficient boom and bucket motion times as well as the strong power to weight ratio makes the LF-10 NEO one of the best in class” says Ingo Rath, Product Line Manager Loaders at GHH in Germany. With a length of 9,6 m and width of 2,6 m the LF-10 NEO is very compact and versatile for excellent maneuverability in a midseam underground mining environment.

Best in class in the midrange segment

The standard bucket holds 4,6 m3 or 10 tons at 2500 mm width, making loading and unloading easier and more

cost-effective. “GHH installs the watercooled Mercedes OM936 diesel engine with 240 kW which is the best in the 10 ton loader size class”, says Rath. “The large fuel tank also allows for full shift operation with no worry for refuelling mid shift and losing valuable production time”. Exhaust gas emissions complies with EPA Tier 3 or EU Stage IIIA on the standard machine, while EU Stage V is also optionally available. The low fuel consumption, ease of maintainability and robust design as well as durability and reliability of the product all add to the low operating costs.

The LF-10 NEO has a great operators’ compartment which boasts excellent ergonomics, which is evident through the way the controls have been laid out and the general arrangement within the cabin. There is also a nice, large footbox

where we have now drilled well over double the originally planned number of metres. Work is already well underway on the revision of the Hamama West MRE, following the completion of the RC drilling there at the end of August, and we will start working on the Rodruin maiden MRE immediately on receiving the final assays from the drilling programme in early 2023 {….}.The extra time we have been granted will also allow us to continue our ongoing exploration on the Concession as a whole, and we plan to start drilling several of our highly prospective regional targets during 2023, including Abu Gaharish, Semna and our recent new discovery at West Garida, ” he added.

giving the operator significantly more space and comfort, while the excellent visibility rounds off an already well designed operators’ compartment. In general, the loader now comes standard with useful safety and maintainability features such as the Proximity Detection System (PDS) interface, which allows the integration of third-party equipment. And optional wear sensors on the brakes.

Easy operation, seamless integration Like other GHH vehicles, the articulated LF-10 NEO is designed for underground hardrock mining and can be ordered with many options. Also worth mentioning is the seamless integration with electronic monitoring and digital analytics systems “GHH inSiTE”, which provides for great insight into the machine performance and maintenance requirements and can be tailored to customers specific needs. The LF-10 NEO, with an operating weight of around 28 tons manages up to 32 km/h with four-speed transmission and gradients up to 25%. It tips the 10-ton payload in just 2,6 seconds. The NEO joins the company´s mid-range segment of LHD offering, which is one of the most comprehensive on the market: The range of 18 diesel and electric models with payloads from 1 to 21 tons is a weighty factor in choosing the perfect loader. And by the way, the Germans have the same great selection in dump trucks to complement.


Kilimapesa to expand operation at Kilimapesa Gold Mine in Kenya

Caracal Gold’s Kenya’s wholly owned subsidiary, Kilimapesa Gold Pty Ltd (KPG) is set to expand its operations at Kilimapesa Gold Mine in Kenya.

The mine is located in a mining friendly jurisdiction in Narok County. The firm has a mining licence with a JORC resource, an established, producing, shallow underground mine and processing plant as well as an extensive prospecting permit. Gold ore is produced on site and exported to international refiners, offering immediate value uplift through revenue generation. Further upside can be seen through plant expansion and reserve and resource upgrade.

The miner’s objective is to expand its operations by undertaking exploratory drilling and open-cast mining at Kilimapesa Hill. The mine intends to use a combination of reverse circulation

drilling, diamond drilling as well as open-pit mining to complement the underground mining currently in place. The company said it is awaiting approval for the expansion from the National Environment Management Authority (Nema).

Caracal acquired 100% ownership of Kilimapesa last year, and the company was listed on the London Stock Exchange in September. Caracal is also

listed on the Frankfurt Stock Exchange & is currently in the process of being listed on the Nairobi Securities Exchange, which will make Caracal the first gold and related minerals miner on the exchange. “We have had great success on this front to date, with production and processing output both increasing, and exploration drilling successfully growing the resource and ultimately the life of mine,” said CEO Robbie McCrae.

Egypt to develop first certified gold refinery

Egypt is set to develop its first accredited gold refinery. The country’s Minister of Petroleum and Mineral Resources Tarek alMulla confirmed the report and said the project’s goal is to boost country’s mining sector.

The project will be situated in the Marsa Alam area in the Eastern Desert, with development costs reaching $100 million. According to the Minister, the refinery which will serve the region as a whole will help finalize the value chain for gold production by maximizing the local content.

Mulla further explained that the vision for developing the mining sector aims to increase its contribution to the gross domestic product from about half a percent now to five percent within the next two decades. It will also provide a large number of job opportunities and maximize mining activities by issuing more than two hundred exploration licenses annually.

Egypt has a history of gold-mining stretching back to the pharaohs but now has only one commercial gold mine in operation, Centamin’s Sukari, in the eastern desert region. Sukari contributes up to $900 million a year to the Egyptian economy.

The country in general is home to a wealth of mineral resources including gold, copper, silver, zinc, platinum and

a number of other precious and base metals. These resources all lie beneath Egypt’s Eastern desert and the Sinai Peninsula, both part of a geological setting known as the Arabian-Nubian shield. With an estimated 6.7 million ounces of gold, 48 million tons of tantalite (fourth largest reserves in the world), and 50 million tons of coal, Egypt has the potential to be one of the top mining jurisdictions in the world. 5 NEWS

TRX Gold reports fourth quarter and year-end 2022 results

TRX Gold Corporation reported its results for the fourth quarter (“Q4 2022”) and year end August 31, 2022. Financial results will be available on the Company’s website on November 30, 2022.

The TRX Gold team delivered two mill expansions on site at the Buckreef Gold Project. In Q2 2022, Phase 1 of the 1,000 tpd+ mill was commissioned, allowing for an increase in production rates and plant throughput to 360 tonnes per day (“tpd”).

Subsequent to year-end, in September 2022 Buckreef Gold announced successful commissioning of the second phase of the mill expansion to 1,000+ tpd. As a result, since Q2 2022, the production of low-cost, high margin gold ounces has steadily increased each month.

Thanks to TRX Gold’s local employees, contractors, trades people, material suppliers and service providers, the two mill expansions were delivered on time and on budget, at a capital cost of approximately $5.6 million for both phases. Tanzania continues to prove itself as a country that is self-sufficient, dependable and capable. Thanks to these qualities, Buckreef Gold did not experience any slowdowns or cost overruns caused by ongoing global supply chain challenges.

For the year ended August 31, 2022, Buckreef Gold poured 8,874 ounces of gold and sold 8,598 ounces of gold. The Company recognized revenue of $15.1 million, cost of sales of $5.7 million

and cash costs1 of $665 per ounce of gold, generating a strong full year gross profit of $9.4 million, gross profit margin of 62% and Adjusted EBITDA1 of $3.5 million.

For Q4 2022, Buckreef Gold poured 3,619 ounces of gold, a new quarterly production record, exceeding previous production guidance of 750-800 ounces of gold per month. Furthermore, 3,363 ounces of gold were sold, also a new quarterly sales record for the Company, resulting in positive operating cash flow of $2.4 million. Buckreef recognized revenue of $6.0 million in Q4 2022, cost of sales of $1.9 million, and cash costs1 of $560 per ounce of gold, below guidance, generating strong Q4 gross profit of $4.1 million, gross profit margin of 69% and Adjusted EBITDA1 of $2.2 million.

In 2022, the Company drilled over 22,000 meters at Buckreef Gold ($3.7 million) including infill drilling, step-out drilling and grade control drilling. During the year, the Company extended Buckreef Gold’s Main Zone by 300 meters or 30%, to 2.0 kilometers, as a result of its northeast step-out drilling program.

In Q4 2022, an additional drill rig was added to expand the exploration program and, to date, a total of 22 holes representing over 7,592 meters in the

northeast extension of the Buckreef Main Zone, have been completed.

The Company executed an infill drill program at the Main Zone, consisting of 16 drill holes, representing 3,695 meters. Also, during Q4 2022, the Company explored under the South Pit and tested the South Zone extension with 24 drill holes, representing 4,255 meters. Results from both programs are pending. Subsequent to year-end, the Company commenced exploration drilling at the Anfield Zone, where the drill rig is now active with 9 drill holes representing 1,650 meters. Assay results from this program are also pending.

At the end of Q4 2022, TRX Gold had no debt on record, cash of $8.5 million and working capital of $5.4 million after adjusting for liabilities which will only be settled by issuing equity of the Company. During the year, the Company successfully closed three financing transactions providing the Company with additional flexibility and liquidity, if necessary, to help fund acceleration of its growth strategy including: (i) a registered direct offering with a single institutional investor for net proceeds of $6.4 million; (ii) a pre-paid gold purchase agreement with a contract price totaling $5 million with OCIM Metals & Mining SA; and (iii) a purchase agreement with Lincoln Park Capital Fund, LLC (“Lincoln Park”) enabling TRX Gold, in its sole discretion, to sell up to $10 million of its shares to Lincoln Park over a 36-month period.

Black Rock to supply power to Mahenge Graphite Project in Tanzania

Black Rock Mining Limited is set to supply power to Mahenge Graphite Project in Tanzania. The firm inked a non-binding Memorandum of Understanding (MoU) with Tanzania Electric Supply Company Limited (TANESCO) for the energy supply.

The MoU will see a 220kV transmission line constructed to support dependable, renewable, and low-cost grid power. The Mahenge Graphite Project’s enhanced Definitive Feasibility Study (eDFS) considered grid power connectivity to support the Company’s goal of a highly differentiated and sustainable operation. The two associated will implement the project’s design, financing, construction, commissioning, and operation. The

line will also supply power to nearby settlements, including the Ulanga District. It will run from Ifakara and extending to the Mahenge substation for a distribution network inside Ulanga District. A 33kV feeder distribution network will be built from the Mahenge substation to the Mahenge graphite project site.

Tanzania’s grid power output is currently 40 per cent hydropower and 60 per cent natural gas, with the share of hydroelectricity expected to increase. As a result, graphite from Mahenge is expected to have an extremely low carbon intensity compared to peers and one of the world’s lowest carbon footprints of any graphite project. Access

The Bibiani orebodies typically dip near-vertical and are open at depth. Bibiani has initiated an underground mine planning study to define development of an underground mine operation that will access mineralized deposits below the Main Pit and the satellite pits. Asante anticipates the underground mine program initiative will increase annual gold production significantly and proceed from 2025 and extend mine life beyond the period of open pit mining.

Dave Anthony, President and CEO stated, “We are very pleased with the progress that has been achieved at Bibiani. Over the past 12 months the Bibiani Mine Team has established a track record of over achievement and we look forward to increasing the value of this asset. As we gather momentum at the Bibiani Mine, and advance with exploration activities and production improvement initiatives, we look forward to providing further updates.”

to a clean, low-cost energy supply will also help Project economics by providing a sustained, low-cost base that drives a higher-margin operation.

“Grid power would provide a huge multiplier effect for the Mahenge Graphite Project by providing low-cost sustainable power, which should lock Black Rock in the bottom quartile of the cost curve; low carbon, which will differentiate its product in crucial consumer markets; and reliable power for the Ulanga and Mahenge areas, driving the win-win relationship developed under the government’s Framework Agreement and ratified by the Special Mining Licence. Critically, as we navigate the debt and equity finance process, investors should look at this outcome and gain confidence that Black Rock and Faru are focused on our long-term plan to deliver a world-class, sustainable and responsible graphite project at Mahenge,” Black Rock CEO John de Vries. 7

Wits Mining accredited for another five-year regular cycle

The high academic standard at Wits University’s School of Mining Engineering has once again been confirmed by its recent accreditation by the Engineering Council of South Africa (ECSA).

The ECSA accreditation is required every five years, and this cycle will see the School through to 2027, said Head of School Professor Cuthbert Musingwini. This follows a lengthy period of selfevaluation to document activities and processes, after which the ECSA accreditation team visits the School to confirm this evaluation.

During their visit, the ECSA team examines every aspect of the School’s self-evaluation report. It conducts interviews with staff, students, recent graduates, and senior industry representatives and inspects both documentation and facilities to ensure compliance. Laboratory and teaching facilities are inspected and checked

for proper functioning, ensuring that all resources are effectively used.

The ECSA stamp of approval is vital to the careers of Wits Mining graduates, as it permits them to register with ECSA as candidate engineers before they achieve professional engineers status later in their careers. Also, it allows Wits Mining graduates to have their qualifications internationally recognised by employers and universities in other countries

that are signatories to the Washington Accord.

“Being accredited by ECSA therefore puts our graduates at an advantage when they enter the local or global workplace, and when they study further,” said Professor Musingwini. “Accreditation assures the marketplace and academia of our world-class standards of teaching and research.”

The School offers one of the leading mining engineering programmes internationally, and boasts having one of the largest mining engineering programmes in the English-speaking world.

“Student numbers remain high in both undergraduate and postgraduate streams,” he said, “with a significant proportion of the student body coming from countries outside South Africa.”

Epiroc presents world’s first underground mine truck made using fossil-free steel from SSAB

Epiroc pioneers a battery-electric underground mine truck prototype made from fossil-free steel in line with the company’s vision to produce the world’s greenest machines. This partnership with Swedish steelmaker SSAB accelerates the journey towards reduced carbon-dioxide emissions, ultimately helping mining companies reach their climate goals.

In partnership with steel manufacturer SSAB, we now prototype an underground mine truck with a dump box made of fossil-free steel, the batteryelectric Minetruck MT42. The result is a 10-tonne reduction of CO2 emissions per manufactured dump box, the equivalent of taking five gasoline cars out of service for an entire year.

The partnership will help us accelerate the journey to create a more sustainable future, deliver the world’s greenest machines, and support our customers. “Our innovation agenda goes hand in hand with our customers’ sustainability agenda,” says Sami Niiranen, President of Epiroc’s Underground division. “In the shift to a new, low-carbon economy, our products and services will be a key contributor for our customers to meet their climate goals.”

SSAB aims to deliver fossil-free steel to the market in commercial scale during

2026, and delivered the first steel made of hydrogen-reduced iron in 2021. SSAB works with iron ore producer LKAB and energy company Vattenfall in Sweden as part of the HYBRIT initiative to develop a value chain for fossil-free iron- and steel production, replacing coking coal traditionally needed for iron ore-based steelmaking, with fossil-free electricity and hydrogen. This process virtually eliminates carbon dioxide-emissions in steel production.

“The development of new technologies is essential to enable the transition to a low-carbon economy,” says Johnny

Sjöström, head of SSAB Special Steels. “Our fossil-free steel immediately reduces the carbon footprint to near zero without compromising the high quality and properties you would expect from SSAB steels. It is the same steel, just without the negative environmental impact.”

The Minetruck MT42 Battery is a breakthrough for our sustainable innovation. It is a significant step in our company’s ambition to produce cutting-edge, environmentally smart mining equipment. It is emissionsfree in operation, generating a strong positive impact on the climate as well as on operators’ work environment and productivity. “We all play a part in creating a more sustainable future”, says Camilla Goldbeck-Löwe, Vice President Corporate Responsibility at Epiroc. “Our partnership with SSAB has enabled us to present the world’s first underground mine truck made using fossil-free steel.”

Mining: A vital link in the transition to a net-zero economy

Modern society is heavily reliant on metals and minerals and the demand is growing, driven by a combination of global trends. The rising urbanization and higher living standards are pushing up the requirements of construction materials, as well as the minerals used in the electronics and appliances that are part of our daily life. The pursuit of the United Nations’ Sustainable Development Goals (SDG) and the move away from fossil fuels are also driving a significant increase in the demand for the metals and minerals required by low carbon technologies – from Rare Earth Elements for wind turbines and quartz for solar panels to lithium for battery electric vehicles and copper for renewable energy systems. Even in agriculture there is an increasing need for minerals, such as the phosphates in the fertilizers used to produce crops to feed our planet’s growing population.

We are facing the challenge of meeting an unprecedented demand for metals and minerals, which are finite and scarce resources. Recycling rates for materials critical to the energy transition, such as Rare Earth Elements, lithium and graphite, are low and not expected to rise significantly for some time. Even then, recycling alone will be unable to meet the increasing demand, and mining will continue to play the key role in supplying necessary primary resources. It is becoming increasingly important to mine efficiently and sustainably using modern technologies such as sensorbased sorting.

Sustainable mining to support the energy transition: Lithium

In October 2022, the European Parliament and Council have provisionally agreed that all new vehicles registered in Europe must be zero emission by 2035. This agreement

is set to accelerate the adoption of electric cars: according to the European Automobile Manufacturers’ Association, in 2021, 20% of new cars sold in the EU were plug-in and by 2030 this set is expected to rise to 60%. Legislative actions such as this across the world will drive a fast growth in the demand for electric cars, which will require high volumes of lithium for their batteries.

The current production rates of lithium will soon be insufficient to meet this demand. In fact, according to the Benchmark Mineral Intelligence, it will require 78 mines by 2035 (the calculation includes projected volumes of recycled lithium) – this is around six times more production than today. It is essential that mining and processing this element is as sustainable as possible.

Sensor-based sorting technology can significantly contribute to reducing the


environmental footprint of lithium mining and processing in different ways. On the one hand, it is able to selectively reject waste and low-grade ore upstream of processing. This means that less material is processed, resulting in significantly lower usage of energy, water and chemicals. A complementary environmental advantage of this technology is the reduction of wet tailings.

On the other hand, sensor-based sorting technology addresses effectively the challenge of basalt contamination, typical of lithium mines. Due to its high density – similar to that of spodumene – this high-iron, barren material is also concentrated by Dense Media Separation, contaminating the final product. With sensor-based ore sorting technology, it is possible to sort out the basalt and as a consequence to unlock value from existing stockpiles of contaminated materials, achieving a high-purity product.

This was the case at the Galaxy Resources Mt Cattlin mine in Western Australia, which had been stockpiling basalt contaminated material since 2016, while it searched for an effective solution. In 2021 it installed a TOMRA PRO Secondary Laser sorter, and in 9 to 12 months it processed the best part of the 1.2 million tons of stockpiled material, consistently achieving high purity with less than 4% basalt. As Matthew Bateman, Principal Metallurgist at Galaxy Resources said, “with the TOMRA sorter, we are using far more contaminated ore than we would previously have processed.”

Sustainable mining for agriculture: phosphates

Another excellent example of how sensor-based sorting can make a difference is in processing phosphates, recovering the valuable nutrient efficiently and more sustainably. The sorting plant at Wa’ad Al Shamal in Saudi Arabia, with a capacity of around 1900 t/h, is the perfect demonstration of this technology’s potential.

The run-of-mine material contains significant amounts of unwanted flintstone, or chert, which has to be removed before the phosphates are fed downstream for refinement processes. TOMRA’s X-Ray Transmission sorters remove flintstones from the phosphate to reduce silicon content, so that the downstream process can be significantly downsized. This results in much lower consumption of energy, water (as much as 45% less), and flotation reagents. In addition, TOMRA’s sensor-based sorters are able to process larger grain sizes, extract value from materials which

are often discarded as waste when using traditional sorting solutions such as Dense Media Separation.

Collaborating for a sustainable future

To achieve the Paris Agreement goal, countries around the world need to reduce their greenhouse gas emissions to ‘net zero’ by around 2050. This means that every sector must reduce the amount of carbon it puts into the atmosphere. For this to happen, legislation has a critical role to play in addressing market flaws, pushing for environmental compliance, drive investments and create favourable conditions for businesses to invest, and foster alignment of all stakeholders.

Collaboration will be key in all industries, and TOMRA is actively seeking opportunities to build partnerships with the big mining houses and other stakeholders across the mining supply chain. This is the path to achieving a circular economy where mining will play a vital role by supplying the minerals needed for the energy transition and the new low carbon technologies. Collaboration will enable the mining industry to operate sustainably, maximizing the opportunities to reduce its environmental footprint.

TOMRA Mining is already actively contributing to green mining with its sensor-based sorting technologies, enabling mines to maximize the efficiency of their operations, minimize the use of energy and other inputs, and reduce waste as much as possible. Today there are around 190 TOMRA sorters in operation across the world, delivering a reduction in CO2 emissions of 168,945 metric tonnes per year. 13

Mining Indaba Focus on African Minerals Critical for a Greener Future

Focusing on the ways Africa can optimise the opportunity to increase the supply of green metals for global energy demands while creating meaningful value for communities will be the emphasis of Investing in African Mining Indaba 2023 (https://www. which takes place at the CTICC, Cape Town, 6 - 9 February 2023. Green Metals Day, supported by keynote sponsor JOGMEC, will cover the impact of COP27 outcomes on green metal demand and supply; battery metals and carbon neutrality; green metals outlooks; Africa’s hydrogen potential; as well as ways to build domestic manufacturing industries as part of mineral value addition.

African mining and metals are critical to tackling the global climate emergency. Home to 30% of the world’s mineral deposits, including the critical minerals needed in green technologies and renewable energy, the continent is positioning itself to benefit from the green energy transition.

Simon Ford, Portfolio Director for Investing in African Mining Indaba, said “Mining Indaba provides the perfect platform to explore the balance between opportunity and value creation, particularly in the African context where the social licence to operate is as fundamental to success as the commodity being produced.”

A Minerals for Climate Action report released by the World Bank in mid2022 estimates that demand for green metals could increase five-fold by 2050 to meet the growing demand for clean energy technologies. This massive boost in demand for minerals and metals will mean that mineral-rich developing countries, like those in Africa, can drive a net-zero future. “Attracting a share of the investment to low and middle-income countries could contribute to economic growth, jobs and local development,” the bank stated.

“Mining Indaba 2023 theme is ‘Unlocking African Mining Investment: Stability, Security, and Supply’, which explores African mining’s opportunities to tap into the global rush for the raw materials needed to ensure a cleaner future, while

at the same time considering responsible sourcing and sustained, ethical supplies

This view is supported by the International Council of Metals and Mining (ICMM), a foundational partner to Mining Indaba. ICMM President & CEO, Rohitesh Dhawan notes that “Critical minerals are the backbone of the energy transition, but how we source and produce them is just as important as how much we need,”

Supporting the Paris Peace Forum’s call for responsible sourcing and production of critical minerals, the ICMM warned that we are walking on a tightrope between an exponential increase in demand for these minerals, rising geopolitical tensions and urgent action on global issues such as climate change.

Simply put, the ‘green’ version of almost anything means the use of more metals but the ICMM doesn’t see this as a license for industry to mine them at all costs, added Dhawan. 15
African mining and metals are critical to tackling the global climate emergency

ABCDust decarbonization

More mining companies are making bold commitments to decarbonize their operations to reduce business risk and help combat climate change.

The International Council on Mining and Metals (ICMM), which represents 28 mining companies and 35 commodity associations worldwide, recently committed to a scope 1 and 2 net greenhouse gas emissions target by 2050 or earlier, in line with the ambitions of the Paris Agreement.

As suppliers of metals and minerals essential to decarbonization and sustainable development, the industry has a responsibility to minimize its environmental footprint - and it is acting. While the speed and depth of decarbonization initiatives vary across the industry, many mining companies are taking immediate action, investing in areas such as renewable energy and electrification, and improving governance to align with global climate risk reporting standards.

Mining companies are under increasing pressure from various stakeholders to

reduce emissions and address climate risks, which can have a negative financial impact on the company. Financial risk comes from the physical effects of climate change, such as extreme weather events, and the risks of transitioning to a low-carbon economy.

Challenges of Mining Decarbonization in mining depends largely on electrification and renewable energy. In some ways, it is easier to imagine how mining can become carbonfree than other sectors. That doesn’t mean it will be easy.

Distinct or disproportionate drivers

Investors are putting strong pressure on large multinational players in the mining sector, particularly in relation to operational emissions. The rapidly declining cost of renewable energy has made it easier for them to respond. For example, BHP has signed a deal to develop new solar and wind farms in the Australian state of Queensland, which will allow them to run their coal operation in the region on solar power. They hope this will help them reduce their indirect emissions in the country by 20% over five years. BHP is also moving toward green copper by signing renewable energy

contracts that will allow its Escondida and Spence copper mines in Chile to switch to 100% renewables, replacing imported LNG. It has also committed to eliminate groundwater use in Chile by 2030, invest in desalination plants.

With a patchwork of different national and local policies to navigate, many mining companies are designing their decarbonization strategies based on the strictest common denominator and then applying these tactics globally across their organizations. While mining and metals companies hope to price carbon and increase regulation, these are not the main drivers at the moment. Instead, investors and markets are ahead of where governments are, as evidenced by the growing number of companies signaling their decarbonization ambitions.

The supply chain pull is also generally stronger in mining than in other sectors. For example, battery manufacturers are starting to look for carbon-neutral lithium and nickel, while automakers are starting to ask for green steel and aluminum. Market demands like these could become the biggest driver of all. If customers start demanding green products, mining


companies must offer them to stay in the game.

What are the factors that can provide CO2 reduction in mining?

Cots – energy is a substantial and growing proportion of a miner’s cost, accounting for about one-third of the total cost base of mining companies. Most miners anticipate the introduction of a carbon price, which will increase the cost of diesel power.

Consumers – the COVID-19 pandemic has radically changed the sustainability mindset of consumers, with global markets becoming increasingly consumer-driven, social expectations are rising and participants at all stages of the value chain will have higher expectations of them to reduce carbon emissions.

Capital providers – pressure is increasingly being applied by capital providers to meet decarbonization targets in order to access financing for mining projects.

Cots – energy is a substantial and growing proportion of a miner’s cost, accounting for about one-third of the total cost base of mining companies. Most miners anticipate the introduction of a carbon price, which will increase the cost of diesel power.

How mining companies can align their actions to meet the industry’s carbon reduction goals.

Mining companies should ensure that their carbon reduction policies are aligned with industry standards from an ecosystem perspective. This is vital to avoid greenwashing, which occurs when companies claim to be dedicated to carbon reduction for the sake of their reputation, but fail to back up their claims with action.

This alignment is necessary to provide consistent reporting methodologies. Maintaining a social license to operate is crucial for many mining companies. This even affects the company’s employees.

As a result, large multinational corporations are increasingly looking to be at the forefront of environmental challenges to recruit the best talent.

In which areas should the company focus its efforts?

The areas that require decarbonization in mining vary among the different elements that contribute to the success of a mining operation from pit to port.

Decarbonization in mining is required in the following areas:

• Transport;

• Mineral processing;

• Diesel Trucks;

• Supply chain;

• Mineral exploitation;

• Electricity supply;

• Transportation of goods.

Green technology as a decarbonizing agent

Green technology in mining refers to equipment that reduces carbon emissions and mitigates negative environmental effects. Green mining is now a crosscutting concept for the entire industry, where the global mining scenario is already adapting it to its entire process chain.

Green mining alludes to sustainability and the care of each process, such as efficiency in resource extraction, production with less environmental impact, and care for the surrounding communities, among other points. Through this new form of mining, it is expected that the practices within the industries will be optimized and improved to make each process more efficient and conscious.

How can ABC Dust help mines decarbonize their process?

ABCDust is a company focused on developing green technology for smart dust control and soil stabilization. ABCDust’s sustainable solutions help mining companies reduce their C02 emissions:

• Reducing the water used for dust control by 90%, which translates into fewer hours of water transport and energy consumption to move and process water;

• Improving road rolling resistance with our soil stabilization and dust control solutions. Rolling resistance is the energy lost through drag and friction of a tire rolling over a surface. A 10% reduction in rolling resistance would improve fuel economy by approximately 3% to 5% for light and heavy-duty vehicles and improve the life cycle of your tires by up to 5%. Open-pit mines use haul trucks that use an average of 50 liters of diesel fuel per hour. Large mines have a fleet of 70 to 150 haul trucks that operate 24/7/365. This can add up to 300,000 liters of C02 diesel consumption reduction per year, plus

the fuel savings alone;

• Increasing the life of mining roads by reducing the frequency of grading and maintenance required. Also, reducing the need to use aggregates to improve road properties;

• Increasing the life of tires and haul trucks. A better, dust-free road uses fewer tires and extends the life of haul truck suspension systems and filters.

Soil stabilization

We use soil stabilization solutions to improve many types of roads and sites in different industries such as mining, forestry and construction in Canada, Chile, Peru, Colombia and Brazil. Our solutions strengthen the soil and enable it to withstand more pressure and capacity from heavy vehicles, thus improving the logistics of the sites.

We offer a wide range of products (enzymes, polymers, synthetic oils and asphalt emulsions) that have been formulated to meet different road needs and reduce the need for aggregates and road maintenance. Our selection of products for soil stabilization is very economical, environmentally safe, and non-toxic.

Here are some of our solutions for soil stabilization:

• DMS-DS® 100 is specially designed for soil stabilization and dust control of industrial roads, haul roads and tightly compacted surfaces, improving their overall strength and the binding of road materials;

• EZISS PRO® is a natural liquid soil stabilization enzyme, which improves the properties of native/ local soils;

• CHEM-STAB® is a sulfonated

(ionic) chemical based soil stabilizer, formulated with ionizing complexes associated with ion exchange elements;

• SOILCELLS® are high density polyethylene panels used for soil containment. The three-dimensional structure of the cells allows the granular material to be confined and thus avoid any displacement caused by erosion or static or dynamic loads. This versatile material can be used for slope retention, soil reinforcement, road infrastructure and as a retaining wall.

Dust Monitoring

Due to the nature of the comminution and classification processes, the blasting, transporting, crushing and milling of ores makes them major contributors of dust emissions into the air. Workers, the environment and nearby wildlife are all affected.

ABCDust provides a dust monitoring service to its clients that employs the EPA’s PM10-2.5 near reference measurement technology to provide a consistent assessment of dust levels in a variety of environmental circumstances and production levels (Ton/hr). To assess PM10-2.5 dust levels emitted from operations, we employ dust management methods.

Here are some of the features of our dust monitoring solution:

• For PM 10, 5, 4, 2.5, and 1 particle, multi-channel dust levels up to 4,000 mg/m3 are continuously monitored;

• Gravimetric samples are used to describe and quantify mg/m3 dust emissions;

• Modeling of dust emissions using a variety of parameters (winds, humidity, production, material type, etc.);

• Solutions for dust control are suggested (maintenance, dry mist, fine mist, dust collectors, additives, etc.);

• Before and after implementation, improvement options are reviewed;

• Report on emissions both before and after implementation of the measure.

Global decarbonization depends largely on the sustainable mining of minerals and raw materials. A thriving and healthy mining industry is critical to the global economy and supports the innovation needed to mitigate global warming, protect the environment, and develop the circular economy.

Focusing its efforts on the areas of greatest impact by aligning with clean technology and green technology applications is the first major step towards the goal of decarbonization in the industry.

Regardless of the paths taken by mining companies to lower carbon emissions, achieving the reduction targets under the Paris Agreement and meeting the expectations of a more environmentally conscious population are key to the longterm viability of the industry.

ERG and Gécamines restart operations at Boss Mining in the Democratic Republic of Congo

The phased restart of Boss Mining will commence with the processing of the historically mined Kiwana fines at its Luita concession, paving the way for further development

Eurasian Resources Group (ERG) and its joint-venture partner, La Générale des Carrières et des Mines (Gécamines), celebrated the kick-off of the restart of operations at Boss Mining with a ceremony held at its concession on 23 November 2022.

Boss Mining, located in the Lualaba and Haut-Katanga provinces of the Democratic Republic of the Congo (DRC), has a long history of copper and cobalt production from significant openpit resources. Boss Mining was placed into care and maintenance early 2019 to allow for ERG and Gécamines to assess different investments paths and conduct further studies to improve Operations’ economics and sustainability.

Benedikt Sobotka, Chief Executive Officer at ERG, said: “We are not only celebrating the return to production at this time, but also our long-standing partnership with Gécamines and its professional team, without whom this restart would not have been possible. ERG believes that collaboration is the key to building a better future.”

Recognising that mining plays a vital role in the social and economic upliftment of its host communities, ERG aims to develop and scale operations at Boss Mining in a sustainable way to allow for positive, longer-term social, environmental and economic outcomes.

“We are proud that this phase of the restart will create around 750 jobs for

DRC citizens, primarily recruited from the surrounding communities, ensuring that direct members of our communities are the primary beneficiaries of Boss Mining’s activities,” added Sobotka.

Provincial Minister of Interior and Security of the Lualaba Province, Mr. Kapenda Wa Kapenda Déodat, commented: “As a government, we can only rejoice once again because the restarting of an operation means not only the creation of jobs for our population, but also that the tax revenue of the province will increase. And every time there is production, we know that there is a small amount that goes into the government’s tax coffer that helps us develop other sectors of our society.”

The phased restart will concentrate on processing historically mined fines over the next 16 months to produce copper cathodes and cobalt hydroxide. The operation will ramp up over the coming months to its full capacity producing, on average, 1,800t of copper cathode and 300t of cobalt hydroxide a month, by March 2023.

“The current restart is only the beginning of our journey, and will provide financing for further potential development, exploration and other mining-related activities at Boss Mining. I am convinced that the revival of Boss Mining’s activities will allow for the creation of important number of new jobs in the future and the union of countless families from the surrounding communities and the

four corners of the country,” said Chief Executive Officer of Gécamines, Mr. Ntambwe Ngoy Kabongo.

Boss Mining is also currently renewing its five-year ESIA commitments and formalising its Cahier de Charges. Restarting the production will allow Boss Mining to update its commitments and social contribution, in turn supporting the action programme of the DRC President, His Excellency Mr. Félix Antoine Tshisekedi Tshilombo, which aims to improve social conditions through housing, health, education and employment.

“It is important for us to transmit to you the message of encouragement of his Excellency the Governor of Haut Katanga, Mr. Jacques Kyabula Katwe, who sees this restarting of Boss Mining as a vital sign of life returning to the territory of Lubudi and the economic life of our province, Haut Katanga. ERG and Gécamines have our full support for the relaunch of this giant amongst the mines,” assured Provincial Minister of Mines and Hydrocarbons, Mr. Georges Mawine Kaindu. 19

Drilling fluids for mineral exploration

Drilling fluid, also called drilling mud, is used to aid the drilling of boreholes into the earth. Often used while drilling oil and natural gas wells and on exploration drilling rigs. Drilling fluids are also used for much simpler boreholes, such as water wells.

According to the BIS Research analysis, the global drilling fluids market was estimated to be at $6.1 billion in 2021, and it is expected to grow at a CAGR of 7.8% and reach $12.6 billion by 2031. Along with the increasing onshore drilling activities, offshore drilling activities are also expected to increase significantly due to the rise in energy demand, which will lead to further growth in the global drilling fluids market.

The main functions of drilling fluids include providing hydrostatic pressure to prevent formation fluids from entering into the well bore, keeping the drill bit cool and clean during drilling, carrying out drill cuttings, and suspending the drill cuttings while drilling is paused and when the drilling assembly is brought in and out of the hole. The drilling fluid used for a particular job is selected to avoid formation damage and to limit corrosion.

Common drilling fluids are water, bentonite mud, cutting oil, and polymers (both water-based and mud-based).

Water-based drilling fluids are the most commonly used of the mud systems. They are generally less expensive and less difficult to maintain than oil muds, and in some special types of systems, they are almost as shale inhibitive.

Bentonite on the other hand is used in drilling fluids. The bentonite in the flush fluid lubricates and cools the cutting tools whilst protecting against corrosion. As the drilling fluid generates hydrostatic pressure in the borehole, it hinders fluid and gas penetration.

Cutting oil is designed to maximise the life of cutting and drilling equipment; working under extreme pressure, improving performance and extending the life of tools. Cutting oil improves machine finish,

lubricates to reduce tip welding and prevents pitting and metal seizures.

Drilling polymers on the other hand have high molecular weight fluid with the ability to control the well’s fluid loss and to increase the viscosity. There are over four variants of this chemical which can include polyacrylate, Snergistic polymer, polyglycol, XCD polymer or partly hydrolyzed polyacrylamide.

When choosing a drilling fluid, several factors are considered. For example temperature, well type, environmental impact and overall Fluids Performance.

When drilling in places with high temperature, the effectiveness of chemical additives is generally reduced and can lead to changes in viscosity and fluid loss. Drilling fluids which can resist to such environment can be used like the oil based mud systems.

Understanding a well type is crucial to determine the drilling fluid to use. In exploratory drilling for instance, the information about the region are not enough to design mud properties. The designed mud system has to contribute in obtaining the geological information easily and safely. The mud composition has to allow for quick change in case of unexpected changes or problems.

Environmental issues are still the important considerations when planning and implementing for the drilling fluid. For example, in offshore operations, synthetic or mineral oil based systems are used rather than diesel oil based system.

Emerging technologies

Drilling fluid technology is constantly evolving because of the escalating demand brought on by more demanding environmental factors such as high temperature and pressure, tight gas and shale gas reservoirs, as well as rising technical standards such as increased lubricity requirements in air drilling and tightening regulations on oilbased systems due to environmental remediation.

Researchers at Curtin University in Australia for instance have developed new technology for the rapid cleaning and re-use of drilling fluids, paving the way toward more efficient and environmentallyfriendly mineral exploration.

Supported by the Minerals Research Institute of Western Australia (MRIWA) and the Deep Exploration Technology CRC, Dr Masood Mostofi and his research team at the Western Australian School of Mines: Minerals, Energy and Chemical Engineering (WASM: MECE) at Curtin University developed the new technology as part of their ongoing research toward automating fluid monitoring and handling in the drilling industry.

Drillers exploring deep beneath the surface for mineral deposits need specialised fluids to lubricate and cool the active drill head, and that won’t leak away through cracks and porous rocks around the drill site.

“New Coiled Tubing drilling technology being developed for mineral exploration needs much higher volumes of these special fluids than conventional drilling,” said Dr Mostofi.

“We have developed a system that can meet these fluid needs in remote locations where geologists might explore for new mineral deposits, and reduces the risk of releasing fluids that might affect the local environment.

The drilling fluid eliminates the use of hydrocarbons. Also developed is a method of keeping boreholes stable and rapidly separating rock chips and solid materials from the fluid as it returns to the surface.

And as environmental conservation takes centre stage, such innovation that have minimum negative impact on the environment are likely to become commonplace going into the future.


Kamoa Copper’s journey to being one of the world’s lowest greenhouse gas emitters per unit of copper produced

The phased restart of Boss Mining will commence with the processing of the historically mined Kiwana fines at its Luita concession, paving the way for further development

The United Nations’ annual COP27 climate change conference is already well underway in Egypt and the topic of developing and deploying lowcarbon technologies, which are critical for the world to achieve its net-zero targets, is high on the agenda. Because the deployment of low-carbon technologies relies heavily on minerals, the mining sector is critical in the fight against climate change.

Africa, a continent rich in minerals, will play a leading role in the supply of key minerals such as copper, cobalt and platinum group metals. These minerals are critical for renewable energy, hydrogen, and battery energy storage technologies – all of which are required for the clean energy transition. However, this must be addressed against the backdrop of Africa’s climate vulnerability and climate adaptation needs.

By doing its part in prioritising lowcarbon investments and partnerships on the continent and building agency and capability, Kamoa Copper plans to become the first net-zero operational carbon emitter among the world’s top-tier copper producers. We believe that mining companies can be the champions of global decarbonisation, not just in reducing their operational carbon emissions and producing lower carbon minerals and metals, but also in producing the critical raw materials needed to facilitate the global clean energy transition.

In May 2021, Kamoa Copper pledged to achieve net-zero Scope 1 and Scope 2

emissions at its Kamoa Copper Mining Complex in the Democratic Republic of Congo – a commitment that supports the 2015 Paris Agreement on climate change, which aims to sharply cut carbon emissions to reduce the threat of climate change.

Scope 1 emissions are classified as direct greenhouse gas emissions from company-owned and controlled resources, for example from vehicles, equipment, and machinery, while Scope 2 emissions are indirect greenhouse gas emissions, usually from the generation of purchased energy. The Company’s Scope 3 greenhouse emissions are currently calculated from its land and airrelated travel and cover the travel across the operations as well as from our head offices.

Kamoa is already making progress on achieving its net-zero goals. The Company’s mining operations and its Phase 1 and 2 concentrator plants are currently being powered by clean, renewable hydro-generated electricity from the refurbished Mwadingusha hydropower plant. Following the successful upgrade of Turbine #5 at the Inga II hydropower plant, which is currently under way, these two hydropower plants will provide Kamoa Copper access to a combined estimated 256 MW of clean, renewable electricity for Phase 3, the smelter and future expansions, while also benefitting local communities. Meanwhile, the Company has also recently taken delivery of several key pieces of stateof-the-art mining equipment powered by

electric batteries or hydrogen fuel cells, supplied by Swedish original-equipment manufacturer Epiroc. This includes the Minetruck MT65 haulers, the world’s highest payload underground truck in the field, as well as Scooptram ST18 loaders and Boomer 282 face drilling rigs.

In 2021, Kamoa’s Scope 1 emissions were 17,634 tCO2e, while its Scope 2 emissions were zero, thanks to its use of 100% renewable electricity usage. The Company’s Scope 3 emissions (currently calculated on the Company’s land and air travel) totalled 2,091 tCO2e. “Once we achieve net-zero Scope 1 and 2 emissions, we will turn our focus on achieving net-zero total emissions at the Kamoa Copper Mining Complex, which will include Scope 3 emissions and become an industry leader in the fight against climate change,” says Ivanhoe Mines Founder & Co-Chairperson Robert Friedland.

A 2020 independent audit of Kamoa’s greenhouse gas intensity metrics performed by consulting engineering and project implementation firm Hatch, confirmed that the Kamoa will be among the world’s lowest greenhouse gas emitters per unit of copper produced. Copper is an irreplaceable element required in the manufacture of advanced decarbonisation technology including electric vehicles, wind turbines, and solar panels. 23

Why On-line particle distribution analysers are is increasingly becoming popular

Modern technologies

A laser diffraction particle size analyzer uses multiple light detectors, with more detector elements extending sensitivity and size limits. The time needed to measure particle sizes varies by instrument, ranging from 2 seconds to 10 minutes per sample. The light source used by a laser particle size analyzer also affects particle size measuring limits; shorter wavelength violet and UV lasers are better suited to measure submicronsized particles than red lasers.

Laser diffraction particle size analyzers are used to measure the sizes of particles in a material. Particle size is calculated by measuring the angle of light scattered by the particles as they pass through a laser beam. Laser diffraction analyzers are used in many applications, including manufacturing, quality control and product development. Because this technique can continuously measure particle sizes across a wide range, from 10 nm to 3 mm, laser diffraction particle size analyzers are often used in industrial settings.

AParticle Size Distribution Analysis helps determine information about the size and range of particles representative of a given material. This analysis can be performed using a variety of techniques; the most suitable will be determined based on the sample properties and question at hand.

Sieve analysis still is the traditional and most commonly used method for particle size determination. A sieve stack consists of several sieves with increasing aperture size stacked upon each other and the sample is placed on the uppermost sieve. The most common sources of errors are overloading of the sieves, old, worn or damaged sieves or errors in data transfer. It should also be taken into account that the aperture sizes of new standard-compliant sieves are also

subject to certain tolerances. In modern processes, automated online particle size measurement is being embraced more and more by the mineral processing industry because of the distinct advantages it offers over manual offline measurement and the cost efficiencies it is able to deliver.

One advantage of automated on-line particle size measurement is that it provides a continuous stream of data, which allows for smaller changes to be made more often, thereby reducing wastage during reaction time, allowing problems to be rectified before they can escalate further and optimising operational flow. Where the ore being extracted is of particularly high value such as gold, these cost efficiencies can be significant.

Most studies have confirmed that return of investment for on-line laser diffraction occurs anywhere between six months and a year following installation. The biggest reason for this is that there is much less reliance on manpower; manual analysis methods generally necessitate highly-skilled individuals to be working around the clock, while on-line systems only require occasional intervention from a semi-skilled worker, lowering costs in terms of both time and expertise. These lowered man hours have the added benefit of minimising the risk of hazard material exposure.

Image analysis involves processing an image into fundamental components to extract meaningful information. Upon completion of the measurement, results are available on a variety of size, shape, and intensity parameters, such as


Circular Area Diameter, Length/Width, Aspect Ratio, Circularity, Convexity, and Opacity/Transparency along with several others depending on the instrument manufacturer.

Using static imaging, the particulate is dispersed onto a stage where it remains fixed during analysis. Static imaging systems offer versatility in that various sample states can be analyzed: dry powders, liquid suspensions, particulate captured on filters, in addition to creams and lotions. These systems also have the ability to reanalyze the same particles more than once, allowing for more indepth investigation

Ultrasonic attenuation has been applied in wet mineral processes since the 1970s. Because ultrasonic particle size measurement is sensitive to air bubbles, the sample has to be deaerated before measurement. Recently, ultrasonics has been combined with gamma-ray transmission and sound velocity measurement for more accurate solids content compensation (Coghill et al, 2002). The sample volume measured can be relatively large, which is an advantage of this technology. However, the major limitations in mineral processing operations are its sensitivity

to air entrainment, flaky particles, solids content and slurry viscosity changes.


Companies are increasingly adopting on-line methods especially due to their efficiency and ability to detect a problem early enough to act. With off-line particle size measurement, problems can go undetected for hours, but with on-line methods such as laser diffraction, there is constant monitoring of the process and upsets can be detected as they occur.

Again, while with off-line particle size analysis requires the analyst to wait until several samples have been taken and analysed before they can see the outcomes of their changes. With an online particle size analyser, however, this process is much quicker. Assessing new operating scenarios requires nothing more than a new steady state to be established, meaning the changes can be evaluated in minutes.

Launch of Human Rights and Child Labour Indices for Battery Passport

The Global Battery Alliance (“GBA”), a multi-stakeholder organisation to establish a sustainable battery value chain, today launched its Human Rights Index and Child Labour Index for the Battery Passport, ahead of Human Rights Day on 10th December. The indices are the world’s first frameworks to measure and score the efforts of any company or product specific to the battery value chain towards supporting the elimination of child labour and respecting human rights.

The indices were developed by the GBA’s Human Rights and Child Labour working group, led by Levin Sources and including Tesla, UNICEF, Volkswagen, Eurasian Resources Group, Responsible Mica Initiative, and the Cobalt Institute, among other members.

Child labour and human rights violations are a critical and growing issue in the battery supply chain, particularly as demand for batteries continues to increase to achieve the green transition. To address this, the GBA’s indices will incorporate and go beyond existing international standards and frameworks, including guidance from the United Nations, OECD, International Labour Organization and UNICEF. They will enable all reporting companies to more comprehensively assess their performance and that of their products according to more than 100 indicators across their operations, business relationships, and supply chains. To reduce the burden for reporting entities, the indicators include indicative standard equivalency assessments for commonly used responsible mining and sourcing standards.

Alongside the recently published Greenhouse Gas Rulebook to calculate the battery carbon footprint, the Human Rights Index and Child Labour Index will serve as key performance indicators for the GBA’s Battery Passport – a transparency framework integrating technical data, with provenance data and sustainability performance at the product level of the individual battery. In the long term, the GBA will issue a battery quality seal based on data benchmarking to provide consumers with trusted data on a battery’s characteristics, provenance

and ESG performance. In doing so, the Passport will certify whether a battery was produced with respect for human rights, including those child rights that determine the occurrence and severity of child labour. In the future, the Battery Passport may include additional standard equivalencies and automated scoring.

For start-up businesses, or those that are rapidly scaling, these indices offer a checklist for building a robust human rights due diligence system. For companies that already have human rights and/or child labour due diligence systems in place, the indices enable them to run a “health check” on their systems and set out a roadmap to improve their performance, including how to address the root causes.

The current versions of the indices serve as a self-reporting tool for companies and are precursors to more comprehensive indicator frameworks to be developed in 2023. The GBA’s members will work collaboratively to refine the scoring logic, incorporate findings from the pilots, and develop assurance mechanisms for the indices over the next year. While the current versions can be used by companies sourcing from or adjacent to artisanal and small-scale mining (ASM), the GBA plans to roll out additional indices in the future, including a dedicated index for use by ASM producers.

Benedikt Sobotka, Co-Chair of the Global Battery Alliance and CEO of Eurasian Resources Group, said: “It is crucial that rapidly rising demand for batteries does not come at the expense of adults’ or children’s basic human rights. The GBA is proud to have launched these Human Rights and Child Labour Indices, which aim to immediately and urgently eliminate child and forced labour, strengthen communities and respect the human rights of those employed by the battery value chain. The roll-out of these indices has been possible thanks to the GBA’s global, collaborative approach, and we look forward to developing them further with valuable input from our members.”

Inga Petersen, Executive Director of the Global Battery Alliance, said: “These are the first universally applicable indices to measure and score companies’ efforts to control risks and drive positive impacts in relation to child labour and human rights in battery supply chains. The indices are applicable to every enterprise that participates in our flagship Battery Passport or is involved in the production, trade or transportation of battery components. We hope that they will help meaningfully reduce the likelihood and severity of human rights violations and child labour in the battery value chain.”

Tom Einar Jensen, Co-founder and CEO of FREYR, said: “We anticipate significant scale across the battery industry in the coming decades. As we deliver on the immense demand, it is fundamental that we do so sustainably. We must keep the people across our entire value chain top of mind. Everyone must take part in the value creation. It’s about creating job opportunities, building competence, ensuring safe working conditions, generating tax income for municipalities, and making a nature positive impact in our communities. For many new companies like FREYR, the GBA Human Rights and Child Labor Indexes provides both insights as well as guidance on how to secure the rights of all people. We have already learned from this work and will implement the steps and requirements into our processes, contracts and conversations.”

Atle Høie, IndustriALL General Secretary, said: “The battery supply chain is complex


and we welcome the indices as a means to ensure that violations of human rights don’t go undetected. The rights of the workers along this increasingly important value chain need to be respected. Workers’ rights are human rights.”

Fanny Frémont, Executive Director of the Responsible Mica Initiative, said: “As mica is used extensively in electrical batteries and is associated with significant risks of child labour and human rights abuses, it was only natural for the Responsible Mica Initiative to contribute to the definition of these two indices. We are deeply pleased with their publication, and we are confident that they will be useful to the entire industry in identifying and implementing the necessary remedial actions towards eradication of child labour and human rights violations”.

Susannah McLaren, Head of Responsible Sourcing and Sustainability, Cobalt Institute, said: “Building a transparent battery value chain can only be achieved if it is underpinned by robust human rights due diligence aligned with international authoritative frameworks that enables companies to address their most salient issues, beginning with child labour. Over the past two years, the Cobalt Institute is proud to have invested time and effort

in the Global Battery Alliance to bring the battery passport to fruition which we believe can be a catalyst for achieving positive outcomes for people and planet.”

Full list of contributors:

The Child Labour Index and Human Rights Index have been developed through a participatory process led by Levin Sources on behalf of the Global Battery Alliance since January 2021. This index has been drafted by Levin Sources in close consultation with and with significant input from the following contributors: BASF, Battery Associates, Cobalt Institute, Eurasian Resources Group, Everledger, Freyr Battery, GIZ, Glencore, IndustriALL Global Union, Natural Resources Canada, Pact, RCS Global, Renault Group, the Responsible Business Alliance, Responsible Mica Initiative, Tesla, Umicore, UNICEF, and Volkswagen. The following historical contributors are also gratefully acknowledged: IMPACT, the London Metal Exchange, SAFT, The Good Shepherd International Foundation, and Volvo Group.

Alliance for Responsible Mining, RCS Global, Systemiq (on behalf of the Battery Pass Project), The International Institute for Sustainable Development, and The

Centre for Child Rights and Business also provided invaluable guidance to the indices’ development by “stress testing” each index against the themes of auditability, ASM responsiveness, child rights responsiveness, gender responsiveness and EC regulatory alignment.

About the Global Battery Alliance: The Global Battery Alliance (GBA) brings together around 120 leading international organisations, NGOs, industry actors, academics and governments to align collectively in a pre-competitive approach, in order to drive systemic change across the battery value chain. Incubated by the World Economic Forum in 2017 until its incorporation as a notfor-profit organisation in 2022, members of the GBA collaborate to achieve the goals set out in the GBA 2030 Vision and agree to the Ten GBA Guiding Principles.

Mining equipment: suppressing the fire risks

As mine workers continue to work long hours across consecutive shifts, heavy duty mining vehicles and machinery – for overground and underground operations – is often required to work 24/7 to meet tight schedules.

Operating in the high-risk mining environment, with dust, extended use and prolonged vibration all raising risk of equipment overheating, heavy duty mining vehicles are susceptible to increased fire risk.

Fredrik Rosén, business manager, Dafo Vehicle Fire Protection, discusses the various fire risks associated with mining heavy vehicles, particularly as technology advances, and explains the steps mining operators can take to minimise downtime and risk, while maximising safety.

What’s driving fire risks?

Individual site risks will depend on unique risk assessments, which should consider a mine’s overall operations, including how its vehicles and machinery operate in context. There are, however, some key factors that are influencing risk for heavy duty vehicles and machinery for the majority of mines.

1. Overheating

Due to the harsh operating environment, mine vehicles and machinery are inevitably prone to dirt and dust buildup. Of course, maintaining a clean engine compartment does reduce risk for heavy duty equipment. However, in the mining industry, where operations regularly generate excess dust, it can be complicated to keep things clean. If not controlled, this can increase the equipment’s risk of overheating.

While overheating alone doesn’t necessarily lead to fire risk, when combined with other factors, it can increase overall risk of fire.

For example, as mining vehicles are often in operation for extended periods

of time, the prolonged vibration as a result of engine operation can cause friction between vehicle components. Over time, this can increase wear and tear – while also increasing risk of overheating further.

This wear and tear has the potential to cause loose cables and sparks, or damage to vehicle components, for example, causing a leak to the injection pipe of combustion engine vehicles. When combined with overheating, this can lead to dangerous electrical or spray fires, which can spread rapidly.

2. Electrification

As many mine operations drive to improve sustainability and reduce environmental footprints, the adoption of electric vehicles (EVs) in place of traditional combustion engine vehicles is on the rise.

Although naturally less prone to overheating, the lithium-ion batteries that power EVs do bring about different kinds of fire risks. There are four main factors that influence battery fire risks:

• Over or undercharging

• Mechanical influences – for example, crashes or mechanical failures


• Excess heat exposure

• Protection issues, where particles can enter battery cells.

Each of these factors can cause internal short circuits within the battery cells, putting the battery at high risk of thermal runaway – that is, where rapid temperature rises can quickly lead to fire, toxic gas emissions and potentially even large explosions.

EVs require a unique fire protection solution, which is able to detect toxic gas venting before temperatures increase. Traditional fire detection solutions will often only identify thermal runaway after temperatures have begun to rise – which can be irreversible.

3. 3Automation

Exacerbated by the COVID 19 pandemic, automation in mining is at an all-time high, as driverless vehicles being operated remotely are helping to increase operational uptime and reduce health risks for mine workers.

However, driverless vehicles does mean there is often less personnel on site, or in the near proximity of mining vehicles, which can make it more complicated to detect fire risks. This is making automatic

detection and suppression solutions key, as they can increase response time to mitigate risk and minimise downtime and vehicle damage.

How can mine operators reduce the risks?

Mine operators first need to understand the site’s individual risks. As technology onsite changes, it’s important to regularly revisit your risk assessment map, reassessing the suitability of your fire detection and suppression solutions.

All mining vehicles – whether diesel or electric, manual or automatic – bring different fire risks, which should be addressed effectively in your site’s prevention solution.

Suppressing mining fire risk is all about considering the site as a whole, developing a tailored solution that tackles the pertinent risks effectively –all to minimise downtime and maximise safety. 29

ERG and the University of Kolwezi develop curriculum to meet mining skills demand in the DRC

Eurasian Resources Group (ERG) and the University of Kolwezi (UNIKOL) have partnered to launch the ERG Mining Academy, with its first student intake in January 2023. The collaboration will see UNIKOL partnering with global teaching institutions, such as the University of Mons, and ERG as an industry partner, to develop a postgraduate engineering curriculum with a focus on exploration, geology, metallurgy, mining and cross-cutting subjects, including ESG.

Benedikt Sobotka, ERG’s Chief Executive Officer, said: “In addition to producing the critical resources needed for a sustainable future, mining plays a vital role in the social and economic upliftment of its host communities. As an established and growing operator in the DRC, we want to ensure that the communities near us benefit from our operations and evolve alongside our business. We are honoured to work with UNIKOL to equip local engineers with industry-relevant skills that will help them seize opportunities within the sector as it continues to scale.”

200 Congolese nationals holding a civil engineering, or a geology and mines degree from UNIKOL, will be eligible to apply for the programme. This study path will culminate in a recognised Professional Master’s degree, endorsed by the Ministry of Higher and University Education, providing graduates the opportunity to secure highly soughtafter positions within the rapidly-growing mining industry in the DRC.

The DRC has some of the largest reserves of critical minerals required to power the green energy transition. With

most major economies across the globe committed to this shift, the demand for these materials continues to rise. The DRC currently accounts for 73% of the world’s cobalt supply and 9% of globally mined copper – both essential to the production of EV batteries and renewable energy systems.

“The DRC is home to many great resources – one of which is our bright and talented youth. When the programme starts next year, as educators, and community members – we will be proud knowing that we are creating futureready professionals that can enter the workforce and contribute to the overall economic upliftment of our country,” said

Under the collaboration, colloquially referred to as Project Kesho (meaning future), UNIKOL will ensure the delivery of the programme, whereas ERG will provide the resources for its implementation including securing staff, guest lecturers, lecture rooms, multimedia equipment and training opportunities, as well as supporting the development of the programme’s curriculum content and materials. Furthermore, ERG is developing the online learning and management platform where students can re-watch lessons, download course and reference materials, view videos, submit assignments, and communicate with lecturers.

“The ERG-UNIKOL collaboration is an exemplar of an innovative partnership that allow us to invest in Congolese people and position ourselves in regard to the issues of the day, including actively contributing to the global energy transition. The ERG Mining Academy in Lualaba will enable young Congolese to take ownership of the production chain of critical minerals through exploration, production, processing and distribution of raw materials,” said the Minister of Higher and University Education, His Excellency, Mr. Muhindo Nzangi Butondo

Prospective students can apply for this two-year programme until 10 December via

The collaboration, culminating in the ERG Mining Academy, will enhance engineering degrees through a unique post-graduate programme to build critical mining-related competencies

Financing Energy Project Development in Africa

Raising capital for energy projects and building sustainable pipelines is complex in a market that is challenged by demand for fossil fuels, while simultaneously trying to satisfy carbon-neutral policies and commitments. Data shows that despite Africa’s sizeable population, it only attracts sub-5 % of global energy investment.

Undoubtedly, Africa is abundant in opportunities and resources, but many of the continent’s countries have yet to unlock barriers to trade and prove themselves to be reliable global partners. The countries that stand to benefit from energy project development and attract meaningful investments are those with governments that seek to lower risks through pricing reforms, transparent tendering systems, strong anti-corruption law enforcement, and the development of skilled labour.

Experts agree that sustainable economic growth throughout Africa depends on the infrastructural development and distribution of clean energy. This means:

• A move from fossil fuel sources to renewables

• Decentralisation of energy generation, transmission and distribution

• The integration of digital technology to support and speed up transition

To make this shift possible and enable meaningful socio-economic reform, the continent will need more than double the current energy investment by 2030. In real terms, this requires a minimum investment of roughly $1 billion per year.

Between 2016 and 2020, the private sector contributed to 60% of all energy investment in Africa. Public sector enterprises also play an important role, although, in recent years, many public utility companies have been plagued by a high level of debt, requiring capital injections from public finance institutions. It is likely that public entities will become

more valuable as co-investors by helping to lower the perceived risks of financing novel projects. This, in turn, will serve to attract more significant private sector support.

Africa’s clean energy success hinges on the implementation of a wellintegrated financial framework aimed at accelerating green energy projects. Each country has its own unique requirements contextualised by its existing energy supply environment. This makes a one-size-fits-all approach unproductive when it comes to financing solutions. Naturally, investors will also require cooperation from policymakers as well as the governance structures necessary to support the implementation and rollout of purpose-built financial solutions.

Where to look for energy project investment?

Depending on the project, its size and purpose, there is an abundance of funding options available. Below, we list a few of the notable organisations that are helping to power Africa’s renewable energy development projects.

African Renewable Energy Fund (AREF)

Investing in small hydro, wind, geothermal, solar, stranded gas and biomass projects throughout SubSaharan Africa, the AREF aims to invest in up to 12 renewable energy projects. It is a closed-end private equity fund keen to support medium-sized projects at all development stages that aim to produce an energy output between 5 and 50 MW.

Energy and Environment Partnership Trust Fund (EEP Africa)

Hosted and managed by the Nordic Development Fund (NDF), the EEP is aligned with the targets set by the Paris Agreement on climate change and sustainable development.

Present in 15 countries throughout southern and east Africa, the EEP provides not only early-stage grant and

catalytic financing but also technical support and knowledge enrichment.

Sustainable Energy Fund for Africa (SEFA)

Established in 2011, SEFA is a multidonor facility backed by leading global economies such as the United Kingdom, Denmark and the United States. The fund helps to unlock private investments for small to medium-scale sustainable energy projects in cooperation with the Africa Hub.

Africa finds itself in a unique position where energy supply is concerned. Keen to industrialise and plug into the global digital supply chain, its leaders recognise that sustainable renewable energy development will play a pivotal role in how the continent meets its ambitious goals and supports the demands of a relatively young demographic. While large-scale infrastructural projects are necessary to facilitate this development, investors also have the unique opportunity to contribute towards small and medium-sized projects that will play an essential role in bringing connectivity and upliftment to the continent’s widely scattered communities.

The aspect of financing energy project development will take centre stage at the upcoming Africa Energy Indaba CEO Roundtable as a key discussion topic. Energy CEOs invested in or affected by the energy landscape, be it directly or indirectly, will gain considerable insight from attending this invaluable, prevalent and thought-provoking dialogue. The Africa Energy Indaba, has continued on its growth trajectory and remains Africa’s most prestigious energy event and has demonstrated impactful initiatives in fostering significant business liaisons, forging gateways for industry stakeholders into new markets and exploring challenges and opportunities to promote innovation in energy operations.

A Grinaker-LTA Civil Engineering project well worth its ‘salt’

First concentrated solar thermal power plant with molten salt central receiver

Grinaker-LTA’s role in the Redstone

Concentrated Solar Thermal (CSP) power plant project in the Northern Cape, which is the largest investment made to date in terms of the South African Renewable Energy Independent Power Producer (REIPP) Procurement Programme, consists of the construction of package C3 civils permanent works.

This has afforded Grinaker-LTA the opportunity to gain a firm foothold in the growing local renewable energy space. The national importance of this pivotal renewable energy project was also underscored by an official visit by

President Cyril Ramaphosa, who toured the site recently.

Abdool Shaikh, Managing Executive of Grinaker-LTA’s Civil Engineering division, clarifies that President Ramaphosa, together with the client and an entourage comprising various government members and local dignitaries, took part in a site visit to Redstone CSP power plant in October.

“This was a real honour for all parties concerned in the construction of this landmark renewable energy project,” he enthuses.

“President Ramaphosa took a keen interest in all facets of the project, paying close attention to the detailed full-scale model of the CSP power plant, before donning the requisite personal protective equipment (PPE) and inspecting the site.

As a tier-one, 100 percent black-owned construction company, Grinaker-LTA is pleased and proud to have been part of this event – and to have played a role in the construction of this ground-breaking renewable energy power plant,” he adds.

Project overview

The 100MW Redstone CSP plant, which forms part of the South African


Renewable Energy Independent Power Producer (REIPP) Procurement Programme, is the first project-financed CSP with molten salt central receiver in the world, and also one of the largest investments in South Africa under the REIPP. Following commissioning, commercial operation is scheduled to commence towards the end of 2023.

With 12 hours of full-load energy storage, Redstone will be able to reliably deliver a stable electricity supply to more than 200,000 South African homes during peak demand periods, even well after the sun has set.

Grinaker-LTA’s role

As bid leader on the project, GrinakerLTA Civil Engineering division’s General Manager Chris Tshivhidzo was responsible for overseeing operations on the project execution, while managing the construction schedule and the budget. Tshivhidzo clarifies that the company was awarded the civil permanent package C3 work by international investors.

He explains: “ACWA Power, a leading Saudi developer, investor and operator of power generation plants, and Chinese engineering company SEPCOIII Electric Power Construction Limited, managed the project - and they required a reputable contractor to execute the construction of the project’s critical structures.”

Tshivhidzo adds that the experience of working with an international, diverse and multi-cultural client proved to be interesting and a worthwhile learning experience for the Grinaker-LTA team.”

Tshivhidzo outlines that the contract awarded to Grinaker-LTA’s Civil Engineering division consisted of the scope of work to construct the following critical structures in the thermal power plant:

• Steam generation structure

• Molten salt pumps structure

• Hot salt storage tank

• Cold salt storage tank

• Water treatment plant civils

• Fire protection water pump house civils

• Demineralised water storage tank

• Effluent collection area

• Retaining wall

Tshivhidzo notes that the GrinakerLTA section of the project is due to be

completed in December 2022 - with the overall project scheduled for completion in 2024 - and that ACWA Power and SEPCOII managed the project extremely well.


Tshivhidzo clarifies that major challenges involved in the project include tight timelines and a tight budget, management of engineering changes required, and also integrating the different ways in which teams from three countries – Saudi Arabia, China and South Africa - work.

“We addressed these through wise use of resources, positive contract negotiations, and adopting a mindset that was willing and able to adapt to different cultural expectations and ideas,” he says.

“Grinaker-LTA was pleased to assist our international clients, smoothing the way as they adjusted to the South African construction environment. This included many aspects, from gaining an understanding of South African labour laws, local weather and physical conditions on site - to the requirements of partnering with local communities and businesses.”

Community upliftment

“The project is also having a positive impact on the local community and economy overall,” advises Tshivhidzo, “by opening job opportunities and

upskilling local labour, as well as using local suppliers and sub-contractors. We have employed 80 local employees who received on-site training and development. We have also partnered with 20 local businesses that are providing us with products and services. As a company, Grinaker-LTA prioritises local spending and development of community businesses on our projects wherever possible.”

Shaikh notes that Grinaker-LTA’s participation in the Redstone CSP project is a source of immense pride to the company: “This is a milestone REIPP, fast-track project requiring rapid, responsive management and also involving multi-national companies which have invested significantly in the global – and local - renewable energy market. We are pleased and humbled to be playing an active role in supporting South Africa’s renewable energy programme and facilitating energy generation, for the future sustainability of the country as a whole.

As Grinaker-LTA, we look forward to completing our section of this pivotal renewable energy project on time and on budget in December this year – and to continuing to play a keystone role in similar projects which will contribute to energy security and benefit the economy and South Africa as a whole,” he concludes. 35

Industrial plant demolition and decontamination

Industrial plant demolition and decontamination work ranges from the removal of critically compromised structural steel structures and elements to the recovery of undamaged client assets and the demolition of plant buildings and offices. Jet Demolition also carries out clean-up operations whereby it reduces hazardous contaminant levels on the demolished elements, resulting in materials being recycled and reused.

This represents some of the most demanding, time sensitive and technically

challenging projects undertaken by the company, says Jet Demolition Contracts and Project Manager Kate Bester. The scope of work ranges from the safe and controlled demolition of coal-fired boilers to product conveyors, steam turbines, transformers, silos, cooling towers and associated auxiliary equipment, in addition to the removal of hazardous materials.

The timeframe is directly related to the project and client requirements, combined with a heightened attention to health and

safety. With the safety of its personnel and all other persons involved being of the utmost importance, Jet Demolition ensures that its projects are highly mechanised. “These types of projects add to our diverse portfolio. By careful application of our experience, we offer our clients solutions that are economical, rapid and risk averse,” highlights Bester.

The main equipment used depends on the site conditions. For example, stateof-the-art cold-cutting equipment allows workers to operate safely in the most volatile environments without affecting the client’s operational processes. Plant and equipment range from a one-tonne skidsteer loader to a 102-tonne highreach excavator, paired with the ideal demolition shear, grapple, hammer or bucket as required.

Full-time on-site production and safety management professionals oversee skilled operators and multi-skilled demolition workers. These operational teams are supplemented by Jet Demolition’s in-house engineering and project management teams, supported by SHERQ, warehouse and workshop departments.

The main challenges posed by these type of demolition projects is having to accommodate live services that could be compromised within the demolition works area and the associated structural elements that must not be damaged.

Maamba Collieries Limited wins ZACCI awards for sustainable workforce

Maamba Collieries Limited has been recognised by the Zambia Chamber of Commerce and Industry (ZACCI) for its best practices in managing its workforce and resilience during the pandemic.

Under the theme “Business Resilience, Using Disruptions to Bounce Back”, ZACCI recognised MCL’s sustainable workforce and resilience through innovation as key factors in building a positive dynamic industry that generates a supportive work environment promoting well-being, worker attitudes and increased efficiency in the use of resources.

the company was honoured to receive the two awards from the ZACCI.

MCL received two awards –first prize for the best sustainable workforce, and second place as a resilient industry innovation leader at the event, which was graced by Minister of Green Economy and Environment, Eng. Collins Nzovu.

This year’s theme strongly resonated with MCL, because since privatisation, the company has faced challenges, but has remained steadfast in its commitment to contribute to the country’s energy basket and economy.

MCL’s success as Zambia’s largest coal producer is largely attributed to its workforce, and the company believes that

no business entity can achieve greater sustainability without the involvement of a motivated workforce. Therefore, since it began operations, the company has dedicated itself to safeguarding the health, safety and welfare of its most cherished asset – its employees.

MCL employs some 1,500 people, more than 85 per cent of whom are indigenous Zambians and remains committed to building lasting relationships that have long-term impact to help continuously improve, grow and promote economic development with ZACCI and industry stakeholders in areas and sectors of business that play a pivotal role in the sustainability of the energy sector and economy at large.
