Zambia's defining endowment is the Central African Copperbelt. The audit records the world's second-largest copper reserve base at approximately 21,000 thousand tonnes of contained copper (USGS Mineral Commodity Summaries 2025), roughly 2.1 per cent of global reserves, at ore grades of 2 to 3 per cent against a global average of 0.5 to 0.8 per cent. Mine production is given as 712,000 tonnes in 2023 and 680,000 tonnes estimated for 2024 by USGS, while the Zambian Ministry of Mines and ZIPAR cite approximately 820,000 tonnes for 2024 on recovery at Konkola and Mopani plus the new Mimbula mine; the audit cites both figures and flags the conflict. Zambia is Africa's second-largest copper producer after the DRC and eighth to ninth in the world, with copper and its by-products at some 70 to 75 per cent of export earnings. Secondary endowments include cobalt, nickel and manganese as Copperbelt by-products, and emeralds: Kagem, held 75 per cent by Gemfields and 25 per cent by GRZ-IDC, is the world's single largest emerald mine at some 25 to 30 per cent of global supply, producing 159,351 carats of premium emeralds in 2024 and generating cumulative auction sales revenue of USD 1.1 billion across 51 auctions since July 2009, with mining paused from 1 January 2025 amid emerald oversupply.
Unusually for Africa, the processing position is genuinely built rather than announced. Four smelters operate: Kansanshi (First Quantum Minerals, approximately 300,000 tonnes per annum of anode plus over 1 million tonnes per annum of sulphuric acid), Mufulira/Mopani (ISASMELT, with a refinery of approximately 220,000 tonnes per annum of LME Grade A cathode), Nkana (KCM, the largest primary smelter) and Chambishi (CNMC). Combined finished-copper capacity is approximately 1.2 million tonnes per year, Africa's largest smelting base. Downstream, ZAMEFA (Metal Fabricators of Zambia, Reunert-controlled) holds copper rod capacity of 32,000 tonnes per year, running at approximately 18,000 tonnes per year, and manufactures cables and wire to 800 mm2; exports were approximately 74 per cent of revenue in FY2025, shipping to South Africa, Botswana, Kenya, Tanzania and the DRC. Neelkanth Cables in Ndola is a second cable maker. Beyond copper, cement capacity stands at approximately 3.6 million tonnes nationally against approximately 2.1 million tonnes of demand, sulphuric acid arises at approximately 700,000 tonnes at Kansanshi, and installed electricity capacity was approximately 3,777 MW at 31 July 2024 rising to approximately 3,986 MW by mid-2025, some 85 per cent hydro, anchored on Kariba North Bank (1,080 MW), Kafue Gorge (990 MW), Kafue Gorge Lower (750 MW) and Maamba Collieries (approximately 300 MW).
On complexity the trajectory is negative. The Harvard Growth Lab Atlas of Economic Complexity ranks Zambia 104th and states the economy has become less complex, worsening 15 positions in the ECI ranking, driven by a lack of diversification of exports. The OEC reports an ECI value of about minus 0.65 (rank approximately 94) for 2023, while UNCTAD characterises complexity as around minus 0.4 over the past decade, below the global average of zero; ranks differ by data-cleaning methodology and the audit reports them as a range. Products with revealed comparative advantage above 1 are dominantly copper-centric: unrefined copper, refined copper, copper ores and concentrates, cobalt, electrical energy, unmanufactured tobacco, cement, precious and semi-precious stones, sulphur, zinc ores and raw sugar. A UNCTAD rapid assessment identifies approximately 412 potential products, with the densest and most feasible cluster being copper articles, fabricated metals, industrial chemicals (sulphuric acid) and food processing — the value-addition step adjacent to existing capabilities rather than a leap to unrelated complex goods. The Growth Lab projects approximately 3.5 per cent annual growth to 2034, driven by copper price and volume rather than complexity gains.
The endowment in depth
Zambia's defining endowment is the Central African Copperbelt. It holds the world's second-largest copper reserve base at roughly 21,000 thousand tonnes of contained copper (USGS Mineral Commodity Summaries 2025), about 2.1% of global reserves, at high ore grades of 2-3% against a global average of 0.5-0.8%. Mine production was 712,000 tonnes in 2023 and an estimated 680,000 tonnes in 2024 per USGS, though the Ministry of Mines and ZIPAR cite around 820,000 tonnes for 2024 on recovery at Konkola and Mopani plus the new Mimbula mine (both figures are cited; the conflict is noted). This makes Zambia the world's eighth-to-ninth-largest copper producer and Africa's second after the DRC. Refinery output, by contrast, fell from 222,000 tonnes in 2023 to an estimated 170,000 tonnes in 2024 under power shortages. Cobalt is recovered as a copper by-product from the stratiform deposits that Zambia shares with the DRC within the roughly 25 Mt global terrestrial resource, but Zambian output is a small fraction of the DRC's. Gold, nickel, manganese, zinc and lead occur in modest quantities, with gold, nickel and emerald output rising in 2024. In gemstones the position is world-class: Kagem (Gemfields 75% / GRZ-IDC 25%) is the world's single largest emerald mine, producing 159,351 carats of premium emeralds in 2024 and generating cumulative auction sales of USD 1.1 billion across 51 auctions since July 2009, with mining paused from 1 January 2025 amid oversupply.
The energy endowment is large but hydrology-exposed. Installed capacity was about 3,777 MW at 31 July 2024, rising to roughly 3,986 MW by mid-2025, of which some 85% is hydro. The major stations are Kariba North Bank (1,080 MW), Kafue Gorge (990 MW), Kafue Gorge Lower (750 MW), Itezhi-Tezhi (120 MW) and Victoria Falls (108 MW), with Maamba Collieries coal (about 300 MW) the largest IPP and solar rising via Chisamba (100 MW, commissioned June 2025). The 2023-24 El Nino drought collapsed Kariba to about 7.7% live storage by September 2024, cutting available generation to roughly 1,040 MW against about 2,400 MW peak demand — a deficit of up to 1,360 MW that forced up to 21-hour load-shedding. Zambia is a SAPP member with an existing CEC-SNEL 220 kV interconnector to the DRC (upgrading to 550 MW) and reported power-export contracts to Botswana, Zimbabwe, Namibia and the DRC of about USD 430 million. Untapped potential is substantial: roughly 6,000 MW of hydro, about 2,300 MW of solar and around 3,000 MW of wind, largely undeveloped.
Agriculture is sizeable but rain-fed and volatile, while the industrial base is anchored by copper processing that is rare on the continent. Maize, the staple, fell to 685,000 tonnes in 2024/25 (USDA FAS) against roughly 1.4-1.7 Mt in normal years; soybeans reached about 604,000 tonnes (2023/24) as a regional growth crop; Zambia Sugar's (Illovo) Nakambala estate produced around 397,000 tonnes (FY2021) at among Africa's lower costs, exporting to the DRC, the region and the EU; tobacco exports were about USD 164 million in 2023, alongside cotton, groundnuts, cassava, sunflower and wheat (about 35,000 tonnes). Capture fisheries on Kariba, Kafue and Bangweulu plus growing aquaculture are present, though timber processing is thin. Manufacturing value added is roughly 8-10% of GDP, dominated by food, beverages and tobacco (about 32% of MVA per UNIDO) and chemicals (about 10%). The core industrial asset is copper: four smelters — Kansanshi (FQM, about 300,000 tpa anode plus over 1 Mtpa sulphuric acid), Mufulira/Mopani (ISASMELT; refinery about 220,000 tpa LME Grade A cathode), Nkana (KCM, the largest primary smelter) and Chambishi (CNMC) — give combined finished-copper capacity of about 1.2 Mt/yr, Africa's largest smelting base. Downstream, ZAMEFA (Reunert-controlled) has copper rod capacity of 32,000 t/yr (running near 18,000 t/yr) and makes cables and wire to 800 mm2, with exports at about 74% of revenue in FY2025 to South Africa, Botswana, Kenya, Tanzania and the DRC; Neelkanth Cables (Ndola) is a second cable maker. Other capacity includes cement (national capacity about 3.6 Mt against roughly 2.1 Mt demand — an exportable surplus), sulphuric acid (about 700,000 t at Kansanshi), the Indeni petroleum refinery (Ndola), sugar and beverages, with SEZs at Lusaka South, Lusaka East, Chambishi and Roma and a new Kafue MFEZ (2024, about USD 300 million) planned for vehicle assembly, steel and food processing.
Human capital and logistics are the binding weaknesses beneath the endowment. The labour force is large and young, but roughly 75% of the population is in agriculture while mining, at about 13% of GDP, provides only around 2.5% of employment; the World Bank (September 2025) projects direct mining employment could rise fourfold from 56,000 to 200,000 jobs, plus 300,000 indirect and induced, if the 3 Mt copper target is met. The skills base is a hard ceiling: only 800 students graduated in 2023 from institutions meeting industry-recognised quality standards, and just one in five held the qualifications needed for technician or artisan roles, against a need exceeding 5,000 per year, even as about 93% of mine workers are Zambian nationals; Copperbelt University and the University of Zambia supply mining, metallurgy and engineering programmes. Being landlocked, every export crosses at least one border via the TAZARA railway and TANZAM highway to Dar es Salaam, the Beira and Nacala corridors through Mozambique, the North-South corridor to Durban, or the emerging Lobito Corridor to the Atlantic through Angola (about USD 5 billion Solwezi-Lobito rail, feasibility around 2025); China agreed a roughly USD 1.4 billion TAZARA rehabilitation (2024-25). Transit cost and dwell time materially exceed coastal peers, and the World Bank LPI 2023 is modest — the central deliverability penalty on every export category.
Economic complexity & comparative advantage
Zambia is a low-complexity, resource-concentrated economy on a negative trajectory. The Harvard Growth Lab Atlas of Economic Complexity ranks it 104th and states the economy "has become less complex, worsening 15 positions in the ECI ranking... driven by a lack of diversification of exports." The OEC reports an ECI value of about -0.65 (rank around 94) for 2023, while UNCTAD characterises complexity as "around -0.4 over the past decade," below the global average of 0; the ranks differ by data-cleaning methodology and are reported as a range. The Growth Lab nonetheless projects roughly 3.5% annual growth to 2034 (top quartile), but driven by copper price and volume rather than complexity gains. The products in which Zambia holds a revealed comparative advantage (RCA greater than 1) are dominantly copper-centric: unrefined copper (HS 7402), refined copper (HS 7403), copper ores and concentrates (HS 2603), cobalt, electrical energy (HS 2716), unmanufactured tobacco (HS 2401), cement (HS 2523), emeralds, sulphur, zinc ores and raw sugar.
The feasible diversification path lies adjacent to existing capabilities rather than in a leap to unrelated complex goods. The Atlas notes "a moderate number of opportunities... using existing knowhow," and a UNCTAD rapid assessment identifies about 412 potential products across chemicals, iron and steel, machinery, plastics, paper, electrical equipment, copper articles and food processing. The densest and most feasible cluster is copper articles, fabricated metals, industrial chemicals (sulphuric acid) and food processing — the value-addition step immediately adjacent to Zambia's smelting, refining and agro-processing base.
The trump card · the single strongest continental position
Zambia's single defensible continental advantage is not raw copper — the DRC out-produces it — but its integrated copper value chain, running from cathode to wire rod and cable (HS 7403, 7408, 8544) and unique in sub-Saharan Africa outside South Africa. The endowment is real (reserves of about 21 Mt of contained copper, USGS 2025; mine output of roughly 680-820 kt in 2024) and the processing position is genuinely advanced. Four operating smelters give Zambia the continent's largest smelting capacity at about 1.2 Mt/yr of finished copper (Mining For Zambia); Mopani's Mufulira refinery produces LME Grade A cathode at 99.99% purity against a 220,000 tpa nameplate; and, decisively, ZAMEFA already manufactures copper rod and cable, exporting about 74% of output to South Africa, Botswana, Kenya, Tanzania and the DRC (Reunert FY2025). No other African producer combines reserves, smelting, refining and an exporting fabricator in one jurisdiction.
The continental demand prize is large and substitutable. Per IndexBox, Africa's copper-wire market reached 3.8 million tonnes (valued at USD 36.5 billion) in 2024, and the continent is a net importer, with top consumers Nigeria (573K t), Ethiopia (403K t) and Egypt (266K t) sourcing fabricated wire and cable largely from China, India and Dubai. The honest limits are equally clear. Smelting and refining are electricity-intensive and Kariba is climate-exposed; the persistent roughly 3:1 raw-to-refined export ratio — raw or unrefined copper of about USD 5.03 billion in 2023 against refined copper of about USD 1.63 billion — shows beneficiation stalling rather than advancing; cathode priced at LME plus a roughly USD 250-350/t logistics penalty makes local fabrication uncompetitive against subsidised Chinese product; and landlocked transit costs compound every shipment. The endowment is necessary but not sufficient, and power, logistics and cost-competitiveness gate delivery.
