During a media briefing, Barrick president and CEO Mark Bristow emphasised Twiga’s leadership in Tanzania’s extractive sector, highlighting job creation, local business support, and substantial community investments.

“We spent US$573mn on national suppliers and service providers last year, representing about 83% of our total spend in-country. Additionally, 75% of all our payments to suppliers and service providers went to indigenous companies, exceeding our target of 61%,” Bristow said.

Sustainable mining success?

With a strong commitment to local employment, 96% of Barrick’s 6,185-strong workforce are Tanzanian nationals, 53% of whom come from communities near the mines. The company invested over US$5mn in 2024 in potable water, healthcare, and education, bringing total community investments to US$15.8mn since Twiga’s formation in 2019.

Production guidance for Bulyanhulu and North Mara in 2024 exceeded 500,000 ounces, reinforcing the sites’ Tier One1 complex status. Additionally, both mines completed a full year without a Lost-Time Injury.

Buzwagi made significant strides in its closure plan, focusing on environmental management, water conservation, and vegetation maintenance. A Special Economic Zone (SEZ) is also progressing, attracting investor interest, with one company already obtaining Export Processing Zone registration.

The Barrick Academy, established at Buzwagi in 2024, is making significant progress in developing talent. Focused on training foremen, supervisors, and superintendents, the academy has trained 1,700 individuals to date and is set to surpass its target of 2,800 trained personnel by the end of 2025.

Continued conversion drilling at North Mara and Bulyanhulu has replenished reserves, while exploration efforts have expanded Barrick’s footprint in the Nzega District. The company has secured over 2,000km² of new exploration areas to support long-term mineral reserve growth in Tanzania.

Twiga received multiple industry recognitions over the past year for its safety measures, employer excellence, environmental practices, and community engagement. In 2024, North Mara was named the largest economic contributor in Tanzania’s extractive industry and earned awards for occupational health and safety, corporate social responsibility, and compliance with local content regulations.

“Barrick’s work in Tanzania is a model for sustainable mining that balances economic, environmental, and social responsibility,” said Bristow. “The recognition we have received speaks to our commitment to excellence and the value we bring to our host countries.”

At the African Mining Indaba 2025 in Cape Town, the African Export-Import Bank (Afreximbank) urged African nations to take control of their natural resources, create employment opportunities, and establish industries that foster long-term prosperity

Addressing an audience of African leaders, policymakers, mining executives, and global stakeholders, the bank emphasised the need for strategic transformation in the continent’s mining sector.

Speaking at the ministerial symposium, Denys Denya, Afreximbank’s senior executive vice-president, underscored that Africa stood at a pivotal moment. He warned that the continent must choose between continuing to export its raw materials with minimal returns or implementing decisive measures to take ownership of its resources.

“While the global mining industry generated approximately US$1.7 trillion in revenue in 2023, Africa’s share of this wealth remains disproportionately low. Our continent extracts the raw materials that power the world’s industries, yet it is estimated that we retain as little as between 4% and 20% of the total value of our minerals due to minimal local processing and limited downstream development. The result? Lost economic opportunities, exposure to volatile commodity cycles and a persistent reliance on external markets for refined products derived from our own resources,” stated Denya.

“The choice is ours. The time to act is now. Let us work together: governments, financial institutions, investors, and industry players to build an Africa where mining is not just about extraction but about transformation, innovation and wealth creation,” remarked Denya.

Stronger collaboration

He highlighted that Africa possesses the necessary resources, market potential, and policy frameworks to evolve from a raw materials exporter into a globally competitive industrial powerhouse. However, he stressed that achieving this vision requires decisive action from all stakeholders. “Policymakers must implement clear, enforceable regulations that mandate local value addition and create investment-friendly environments. Private sector investors must step up with capital and technology to develop processing, refining, and manufacturing facilities.”

Denya called for a fundamental shift in Africa’s approach to mining, advocating for investment in refining, smelting, and advanced manufacturing rather than just extraction. “We must move beyond extraction and invest in refining, smelting and advanced manufacturing. African nations must increase local processing capacity for minerals such as bauxite, lithium, cobalt and iron ore,” Denya continued. 

He also stressed the importance of regional cooperation, noting that no single country can develop a complete mining value chain in isolation. He pointed to the African Continental Free Trade Area (AfCFTA) as a key mechanism for strengthening intra-African mineral value chains and fostering cross-border collaboration. Additionally, he emphasised the need for capital investment in mining-related infrastructure, technology transfer, and workforce development.

“Our mining policies must also prioritise environmental, social and governance standards, ensuring that mining benefits communities rather than displacing them,” he added. He argued that such an approach would generate millions of skilled jobs for Africa’s youth, reduce dependence on volatile international markets, and boost intra-African trade.

Reaffirming Afreximbank’s commitment to Africa’s mining sector, Denya revealed that the bank had approved over US$1bn in financing for mining and mineral sector projects over the past three years. This includes funding for a bauxite processing plant in Guinea, support for the expansion of a manganese processing plant in Gabon, and working capital financing for a diamond company in Botswana.

Among other significant initiatives, Afreximbank is backing a petrochemical fertiliser plant in Angola, a titanium dioxide pigment plant in South Africa, and a feasibility study for a limestone processing plant in Malawi.

Denya also highlighted the role of the US$10bn AfCFTA Adjustment Fund, managed by Afreximbank’s investment arm, FEDA, in supporting businesses and countries adapting to the new trade regime. He noted that the bank’s efforts to harmonize standards and implement the Africa Collaborative Transit Guarantee Scheme would ease cross-border movement of minerals and mining equipment, addressing logistical challenges.

Additionally, Afreximbank is leveraging digital solutions such as the Africa Trade Gateway and the Pan-African Payment and Settlement System to enhance market access and streamline transactions. These tools aim to maximise Africa’s mineral wealth for industrialisation, value addition, and economic resilience.

Denya also underscored Afreximbank’s efforts to overcome infrastructure limitations that impede industrial growth. He highlighted the bank’s collaboration with development partners in expanding industrial parks and special economic zones (SEZs).

One of the most groundbreaking initiatives under this framework is the DRC/Zambia Electric Vehicle Battery Manufacturing Special Economic Zones. This project is positioning Africa as a key player in the global energy transition by establishing battery precursor SEZs, enhancing the two nations’ competitiveness in the battery electric vehicle value chain.

Changes are underway at Moolmans, with a new look for one of Africa’s premier mining contractors

While maintaining elements of the company’s proud history within the sector, its new corporate identity and logo – revealed for the first time at the 2025 Investing in African Mining Indaba in Cape Town – reflects the positive changes that are eagerly anticipated for the business over the coming months.

Moolmans has a solid reputation in Africa’s mining industry, with more than 70 years’ experience in different minerals and varied geographies across the continent.

“Our long-standing reputation for exceptional reliability and performance in the industry, is the cornerstone of the strong relationships we enjoy with our clients,” said Moolmans managing director, Rod Dixon.

But this reputation alone is not enough to ensure the company remains a forerunner on the continent, delivering end-to-end open-cut mining and rehabilitation excellence.

“Change is good, especially when it takes us closer to achieving our vision of being the premier mining contractor in Africa, delivering resources for a better future,” added Dixon.

In August 2024, shareholder Aveng announced that it would be exploring alternative ownership options for the tier 1 contract mining business, which would allow Moolmans to pursue focused operating and growth strategies separate from sister company, McConnell Dowell.

“What better time than now to make a change to the already strong Moolmans brand; to visually demonstrate our progressive outlook for the business and our ongoing investment in our people, premier equipment, processes and systems."

Large and diverse fleet

With substantial investment in additional equipment and cutting-edge technologies over the past few years, Moolmans has maintained one of the largest and most diverse fleets of mining equipment in Africa to suit various operational and project requirements and to tackle the most difficult terrains.

“However, delivering innovative solutions for our clients is equally dependent on harnessing the collective strengths of our people, who bring years of experience as well as new and advanced ways of thinking about mining in a world which is increasingly focused on sustainability,” said Dixon.

“Our strong new brand identity is, therefore, just as important internally because, together, we are focused on a common goal – a goal which is focused on crafting a better future for all our stakeholders and delivering prosperity wherever we operate.”

The quest for continuous improvement at Moolmans is being driven by these investments in groundbreaking technology. Things like process automation, real-time data analytics, remote operational centres and artificial intelligence are all being advanced within the business to help drive improved safety, operational and environmental performances.

“Being Africa’s premier contract miner doesn’t only mean that we deliver operational excellence, it also means that we care. We care about whether our employees are proud to work for us, whether our customers are proud to work with us and whether our communities are proud to be associated with us. We care about the environment and about building a sustainable future. We care about the way we do things. The future of mining is here, now, and we are extremely proud and excited to be part of it.”

South Africa's mining giants are exploring renewable diesel feedstock (PHOTO CREDIT: Adobe Stock)

Mining giants Anglo American and its diamond business De Beers are to partner South African energy group Sasol to generate feedstock for renewable diesel production in a bid to curb greenhouse gas emissions (GHG)

The companies have entered into a joint development agreement (JDA) that will lead to a pilot project for the production of feedstock for renewable diesel.

It is regarded as an important step for the companies as they look to establish the value chain for renewable fuels in South Africa.

Biofuels, derived from plant material or animal waste, are among the alternative fuels promoted to reduce carbon emissions.

“This is an important initiative to strengthen our commitment to reducing our greenhouse gas emissions by 2040,” said Alison Atkinson, Anglo American’s projects and development director.

“It is an innovation that contributes to our sustainability journey as a business and our quest to maintain a healthy environment by creating carbon neutral operations.”

Signed against the backdrop of the Investing in African Mining Indaba in Cape Town, the objective of the JDA is to assess the technical and commercial viability of feedstock production, starting with Solaris and Moringa plantations to generate vegetable oil.

Sasol’s existing assets can take a variety of feedstocks, enabling them to produce renewable diesel using vegetable oil quicker than greenfield projects and at lower costs.

“We worked closely with our De Beers colleagues to conceive this partnership given their pre-feasibility studies on renewable diesel production trials within their mining operations and host communities. De Beers is also providing the more than 20-hectare pieces of land on which the trial feedstock will be grown, in Blouberg, Messina; Marble Hall in Limpopo; and the Voorspoed mine closure site in the Free State,” added Atkinson.

Although renewable diesel production in South Africa is not yet at a commercial scale, recent market engagements indicate that the country’s renewable fuels market is promising, driven by end customer demands and their decarbonisation targets, a statement by Sasol read.

“Renewable diesel is transformative,” said Dr Sarushen Pillay, executive vice-president of Sasol’s business building, strategy and technology portfolio, speaking at the signing ceremony. “It meets the technical standards of conventional diesel while significantly reducing greenhouse gas emissions. Our customers can therefore, use it as a ‘drop-in’ fuel in their existing equipment and machinery to meet their greenhouse gas reduction commitments.”

“Partnering with Anglo American, we're investigating the development of a local and cost-effective supply chain for sustainable feedstock, utilising vegetable oil to produce renewable diesel in our facilities. As we innovate for a better world, Sasol’s ambition is clear — to help our customers navigate the energy transition while delivering high-quality, sustainable solutions for a low-carbon future,” concluded Pillay.
