When Anthony Mukutuma walked Zambia’s Minister of Technology and Science through Sentinel’s control systems, the detail that stayed with him was not the automated drills or the trolley lines. It was the quiet. Trained Zambian operators sat at screens, reading fragmentation data, guiding equipment from a secure remote location — managing the first act of a copper mine without standing in its dust. “Innovation is central to how we operate at First Quantum,” said Mukutuma, First Quantum’s Zambia Country Director. “We are proud to show once again that Zambia is at the forefront of modern copper production.”

That observation gives the current Trident story its sharpest frame. Trident is no longer only about scale. It is becoming a story about intelligence.

At Kalumbila in North-Western Province, First Quantum Minerals’ Trident operation brings together Sentinel, one of Africa’s most technically advanced copper mines, and Enterprise, the nickel mine now ramping to full production beside it. First Quantum arrived in Zambia in 1996 with a modest 10,000-tonne operation in Ndola. Today it is one of the world’s top ten copper producers, and Zambia remains its home base. Around Sentinel and Enterprise, something larger has taken shape: a town, a supplier base, a labour economy, a community-investment model and a regional development platform whose influence reaches well beyond the current pit boundary. The next five years will test how much value that platform can create.
 

The Mine-to-Mill Mind

Sentinel’s ultra-class fleet — 48 Komatsu 860E, Komatsu 960E and Liebherr T 284 haul trucks, loaded by Caterpillar 7495HR rope shovels, a Komatsu PC8000 electric shovel and Komatsu PC5500 hydraulic shovels — is the visible expression of a mine built for high-volume throughput. Caterpillar, supported in Zambia through Barloworld Equipment, and Epiroc sit at the production front line: drilling, loading, hauling, keeping the pit advancing through its stages. Hitachi Construction Machinery belongs to the next chapter, through First Quantum’s move toward battery-electric and trolley-compatible haulage.

But Sentinel’s most important work is not found in one machine. It is found in the connections between machines. Three automated drill rigs have been successfully tested at Sentinel in partnership with Flanders Inc., using laser sensors and GPS to improve drill-hole accuracy while allowing operators to guide equipment remotely. The number of holes drilled increased by more than one third. Hole accuracy improved. The human distance from the most hazardous part of the drilling cycle grew.

Before a truck moves, before a shovel loads, the drill pattern has already begun to shape the mine’s performance. Hole accuracy affects blasting. Blasting affects fragmentation. Fragmentation affects crusher behaviour. Crusher behaviour affects mill throughput. In a large, low-grade copper mine, precision at the beginning creates compounding value all the way to the plant.

FragTrack, the Orica-developed fragmentation-analysis system implemented at Sentinel, adds another layer: using machine vision and artificial intelligence, it gives operators real-time data on blast performance and its downstream effects on crushing and recovery. FQM Trident’s implementation was recognised with the Excellence in Industrial Technology and Automation Award at the 2025 ICTAZ Tech Excellence Awards.

 

Minister of Technology and Science Hon. Felix Mutati, who toured Trident’s operations alongside his Permanent Secretary Dr Brilliant Habeenzu and ZICTA Director General Colin Mbula, was direct about what he had witnessed: automated drilling, trolley assist, the rail-run conveyor, mine-to-mill data systems and real-time environmental monitoring. His verdict was pointed. Zambia’s 3-million-tonne copper vision was achievable, he said, precisely because of what he had seen at Trident. Not just more copper. Smarter copper.

 

The Trolley Line, the Conveyor and the Decarbonised Climb

As Sentinel advances through its mining stages, the geometry of the pit keeps changing. Crushers must move. Conveyors must adapt. The recent relocation of in-pit crushers — with In-Pit Crusher 4 scheduled for commissioning in its new position during 2026 — and the commissioning of a rail-run conveyor system are central to that discipline. The conveyor moves ore with lower friction, reduced belt tension and lower electricity demand. It is a practical engineering response to the simple problem of growing haulage distance as a pit deepens.

The Quantum Electra-Haul trolley-assist system is the most visible symbol of Trident’s technology direction. On trolley, loaded trucks travel at 20 kilometres per hour and complete the ramp in approximately three minutes, compared with 11 kilometres per hour and 5.5 minutes off the line. Diesel consumption drops from 650 litres per hour to roughly 50 litres per hour when connected to the overhead line.
 

In practical terms, trolley assist is not just an emissions story. It is a productivity story, a cost story and a mine-design story at the same time.

Covering approximately 8% of Sentinel’s total haulage routes as of the 2025 site assessment — with active expansion across Stage 2, Stage 3 and waste-dump areas — Sentinel’s trolley network is among the most extensive operated by any copper producer worldwide. First Quantum’s 2026–2028 capital programme includes US$25 million for additional trolley installations and US$30 million for continued in-pit crusher relocation. When Zambia’s 2024 drought pushed imported power costs from nine to fourteen cents per kilowatt-hour, the economic case for on-site electrification became sharper still. Reliable grid supply, delivered through partners including Copperbelt Energy Corporation, underpins the economics of the whole system. Weir Minerals, Siemens and ABB complete the processing and electrification picture: slurry handling, drive systems and the broader battery-trolley collaboration with Hitachi Construction Machinery targeting a commercial battery-electric haul truck model in 2028.

 

 

Two Metals, One Platform

Twelve kilometres from Sentinel, Enterprise adds the second metal. A nickel ore body sitting adjacent to a copper ore body and sharing infrastructure with a running copper mine is, as a senior FQM executive has noted, “rather unique in the world.” That shared-cost model makes Enterprise competitive despite nickel price pressure. First Quantum declared commercial production at Enterprise in June 2024. In the fourth quarter of 2025, the mine achieved record quarterly production of 8,750 tonnes of nickel, supported by higher grades and recoveries.

Production guidance for 2026 points to 30,000 to 40,000 contained tonnes, rising toward a life-of-mine average of 40,000 tonnes per year over 10 to 12 years — placing Enterprise among the world’s largest nickel operations by output.

 

The Contractor Ecosystem

Large mines are described by the name of the operator. Projects of Trident’s scale are built and sustained by a far wider circle of specialists. The suppliers and contractors around Sentinel and Enterprise fall naturally into four groups.

 

PRODUCTION AND MINING SYSTEMS

Caterpillar and Barloworld Equipment, Epiroc, Flanders Inc. and Orica sit at the production front line: the drills, blasts, shovels and fleet that convert rock into movement. Komatsu and Liebherr provide the haulage muscle. Their equipment is not interchangeable with anything smaller or cheaper at this scale.

 

ELECTRIFICATION AND PROCESSING

Hitachi Construction Machinery, Siemens, ABB and Weir Minerals support the systems that power, grind, pump, classify and control ore flow. Siemens’ drive technologies form the electrical backbone of the large milling circuit. ABB collaborates with Hitachi and First Quantum on battery-trolley haulage. Weir Minerals handles slurry management and classification. Copperbelt Energy Corporation underpins the grid reliability that makes electrified haulage viable.

 

OPERATIONAL SERVICES AND LOCAL EXECUTION

Kal Tire Mining Group Zambia manages tyre performance across the ultra-class fleet a production-critical discipline in a mine where a truck parked on degraded rubber is a production unit removed from the cycle. Mining Haulage Ltd, KASCCO Group and Quattro Kalumbila provide haulage, earthworks, civil works and field services. NEI Zambia Ltd — Northern Engineering Industries provides the fabrication, mechanical support and technical competence that closes the gap between global equipment and local execution. Afriworks recently delivered the FCP8 Pumping Solution dewatering project: four new high-capacity pumping units installed, commissioned on time, without a single incident.

LOCAL VALUE CHAIN AND COMMUNITY-LINKED ENTERPRISE

Saro Agro Industrial connects the mine’s supply chain to the agricultural livelihood work around Kalumbila a dimension that became nationally significant during the 2024 drought, when First Quantum repurposed 900 to 1,000 copper anode and cathode trucks travelling daily to Walvis Bay and Dar es Salaam to back-haul grain into Zambia on the return journey. The logistics scale of that food-security contribution went largely unreported. Kitwe Processing points toward the downstream value Zambia must continue to develop: specialist processing and industrial participation are the next chapter of the country’s copper story, and the Trident ecosystem is part of that conversation.

Trident is a mine. But it is also a market. Its gravity pulls machinery suppliers, drilling specialists, tyre experts, engineering firms, power partners, agricultural businesses and specialist processors into an economic orbit that extends well beyond Kalumbila.

 

Local Suppliers, Shared Governance and the People-First Test

FQM Trident’s Business Incubation and Supplier Development Programme developed with the Citizens Economic Empowerment Commission and Prospero Limited — has engaged 550 local suppliers and supported more than 300 businesses with ZMW 8.5 million in grants and training. In 2025, more than 80% of Trident’s procurement was sourced locally, approaching US$1 billion in spend with Zambian-registered suppliers. Frederic Wouters, FQM Trident’s Assistant General Manager, has called the programme a bold step toward inclusive economic empowerment. Mineral Link’s journey from support contractor to critical production-based load-and-haul provider at Enterprise Nickel mine — is its most compelling illustration. When Zanaco Chief Executive Mukwandi Chibesakunda travelled to Kalumbila to witness Mineral Link’s operations first-hand, the journey itself was the statement: the CEO of Zambia’s largest bank making the trip to a mine site in North-Western Province to see what a Zambian contractor had built.

The Trident Foundation currently supports 229 students across primary, secondary and tertiary education, including bursaries at Luanshya Technical Business School. The launch of Kwanzangana — derived from the Lunda word for sharing marks a structural shift in how social investment works at Kalumbila. Elected community representatives now work alongside government officials, traditional leaders and the Trident Foundation to decide how development resources are allocated in health, education, agriculture and infrastructure. Trident Foundation Manager Joseph Ngwira described the model’s purpose as empowering communities to shape their own future. Senior Chief Musele Musokantanda IV called it a home-grown solution rooted in fairness, unity and shared responsibility.

Technology can make a mine more efficient. People determine whether it works. The 2025–2026 collective bargaining agreement between FQM Trident, Kansanshi Mining and six major unions delivered a 15% increase in basic salaries from January 2025. For a mine managing pit sequencing, power costs and large-scale capital investment simultaneously, labour stability is part of performance. Technical Training Manager Mulenga Tembo reinforced the safety culture through the mine’s Interdepartmental First Aid Competition, drawing independent confirmation from Zambia Chamber of Mines representative Dr Kamwasha Mumba that one in every five FQM Trident employees is trained in first aid, verified by personal audit.
 

Responsible Mining and Kalumbila’s Post-Mine Future

The rehabilitation programme at Sentinel has restored more than 187 hectares through reforestation and ecological management, supported by an on-site nursery producing 60,000 seedlings annually. The West Lunga Conservation Corridor safeguards more than 1.2 million hectares of forests, rivers and wetlands. The Tailings Storage Facility is monitored by 26 kilometres of fibre optics and satellite imaging updated every 11 days. Approximately 1.5 million single-use plastic bottles per year have been effectively eliminated through on-site water treatment and refillable systems; 650 tonnes of materials are baled and directed to licensed recyclers each month. “FQM’s priority has been to integrate best-available technology into an environmental strategy that safeguards both the environment and the well-being of our communities,” said Kachiwala Sapalo, Trident’s Environmental Manager. A UNDP delegation  joined by representatives from ZEMA and the Ministries of Mines from Zambia and the DRC  visited Trident and reached a complementary conclusion. “FQM Trident’s initiatives provide a strong example of how mining can drive economic growth while protecting the environment,” said UNDP Programme Specialist Chali Selisho.

First Quantum has invested more than US$200 million in Kalumbila Town through the Kalumbila Town Development Corporation, delivering housing, an extended airport runway, schools, healthcare facilities and the MFEZ designation secured in 2022. The town covers more than 5,000 hectares, with plans for 10,000 residential plots and more than 100 hectares of industrial land. “Kalumbila Town can actually be classified as the first privately developed town in Zambia,” said Owen Muyoba, Superintendent for Town Services at KTDC. “The new filling station is more than a fuel stop. It supports our shift from being mine-reliant to a functioning economic hub.” In January 2026, a European Union Delegation toured Sentinel Pit and key social infrastructure including Kalumbila Secondary School and Wumi Mini Hospital  now serving communities that previously travelled more than 90 kilometres for comparable care.
 

Economic Impact and the Next Five Years

In 2025, First Quantum reported a US$3.46 billion economic contribution to Zambia across its operations at Kansanshi and FQM Trident including US$902 million in taxes, US$2.14 billion in local procurement and US$389 million in salaries. FQM Trident contributed US$139 million in taxes and royalties from Kalumbila specifically.

 

Trident’s value is not only what it extracts. It is what it circulates.

Sentinel’s production guidance for 2026 through 2028 sits at 190,000 to 220,000 tonnes of copper per year, with Stage 4 expected to contribute ore from the second half of 2026. The 2026 programme is specific: higher throughput, optimised fragmentation through automated drilling and FragTrack, In-Pit Crusher 4 relocation and commissioning, stronger flotation recovery and continued trolley-assist expansion. Enterprise’s guidance of 30,000 to 40,000 tonnes of nickel for 2026 — rising toward a life-of-mine average of 40,000 tonnes — brings a genuine growth note. FQM is also conducting brownfield exploration around Sentinel to identify life-of-mine extension opportunities, alongside a wider aerial survey of north and north-western Zambia whose results were handed to government in early 2025.

Wouters put the longer aspiration plainly during a stakeholder visit hosted for the Zambia Association of Manufacturers and CEEC: “Through the MFEZ, we want Kalumbila to thrive long after the mine. This is about creating real opportunities for local businesses and families to build their future here.”

 

What Zambia Builds Above It

At Kalumbila, the mine and the town have grown into each other. The drills are becoming automated. The blast data is growing more intelligent. The crushers are moving with the pit. The rail-run conveyor is carrying ore with less friction and less waste. The trolley line is changing the economics of the ramp climb. Enterprise is adding nickel and critical-minerals diversification. Local suppliers are being trained, financed and connected to real procurement. Kwanzangana is putting community development decisions into Zambian hands. Kalumbila is being built to outlast the first chapter of mining.

The future will still demand discipline. Grades change. Equipment wears. Markets move. Communities need evidence that development is real, fair and lasting. But Trident has already proved something that matters well beyond its own boundaries: Zambia can host mines of global scale and technical ambition, attract world-class partners — Caterpillar, Epiroc, Hitachi, Siemens, ABB, Weir Minerals, Kal Tire while building domestic capability through Mineral Link, NEI Zambia, Afriworks, Saro Agro Industrial, Kitwe Processing and the 550 Zambian suppliers in its orbit. It can turn a remote orebody into a working industrial district. It can connect copper and nickel production to schools, hospitals, farmers, contractors and a town designed for a future beyond mining.

The next chapter will be written in automated drill patterns, AI fragmentation data, Stage 4 ore, Enterprise nickel volumes, expanded trolley lines and community-led investment decisions.

And if Trident continues to do what it has done at its best, the story will not only be about what lies beneath Zambia’s ground.

It will be about what Zambia builds above it.
