Tanzania's mineral endowment is among the most varied on the continent. Gold output in 2024 is reported at 51.8 tonnes by the World Gold Council and at 60 tonnes by a USGS-derived series, against reserves of approximately 45 million ounces, worked at Geita (AngloGold Ashanti) and at North Mara and Bulyanhulu (Barrick/Twiga joint venture). The country is the sole world source of tanzanite, drawn from roughly 14 square kilometres in the Mererani Hills, with rough and bead production of 83,014 kilogrammes in 2024. Beyond precious materials it holds the world's approximately fifth-largest graphite reserves at some 18 million tonnes; the Kabanga deposit, one of the world's largest and highest-grade undeveloped nickel sulphide resources, measured and indicated at about 46.8 million tonnes at 2.09 per cent nickel; rare earth reserves of roughly 890,000 tonnes at Ngualla; and exceptionally high-grade helium in the Rukwa Basin, with surface seeps of 10.4 to 10.6 per cent against a 0.3 per cent commercial cut-off and certified prospective resources of 138 to 176 billion cubic feet or more.
The energy and logistics base has changed materially. Confirmed natural gas reserves stand at about 57.54 trillion cubic feet, and installed power capacity roughly doubled with the full commissioning in 2025 of the 2,115 MW Julius Nyerere Hydropower Project, designed for 5,920 GWh a year, against a pre-project base of roughly 1,900 MW. Dar es Salaam port recorded throughput of 27.7 million tonnes in FY2024/25, up from 23.69 million tonnes the previous year and described by the Tanzania Ports Authority as a level not achieved since the port's inception; it handles some 93 to 95 per cent of national trade and serves Zambia, Malawi, the DRC, Burundi, Rwanda, Uganda and Zimbabwe. The electrified Standard Gauge Railway is operational from Dar es Salaam through Morogoro to Dodoma, and TAZARA to Zambia's Copperbelt is under a modernisation of roughly USD 1.4 billion. In agriculture, cashew production reached 189,114 tonnes in 2023, making Tanzania the world's approximately eighth and Africa's fourth producer at around 20 per cent of continental output, alongside tobacco at roughly 107,000 tonnes, coffee at about 55,000 tonnes, tea at about 36,000 tonnes and sisal at about 33,000 tonnes.
The one manufacturing sector that already operates as a net continental supplier is cement. Production reached 10.9 million tonnes in 2024 against domestic demand of 8.5 million tonnes, generating a 2.43 million tonne exportable surplus shipped to Rwanda, Malawi, Mozambique, Burundi, Uganda, the DRC and Zambia. Installed capacity is roughly 11 million tonnes a year across some 13 plants. Against this, Tanzania ranks 116th in the Atlas of Economic Complexity and has worsened 21 positions over the prior decade, with revealed comparative advantage concentrated in low-complexity primary or lightly processed goods.
The endowment in depth
Tanzania's mineral base is anchored by gold, where Tier-1 sources diverge and must be reconciled: the World Gold Council reports 51.8 t of output in 2024, while a USGS-derived series (CEIC) reports 60 t, up from 54.76 t in 2023, against reserves near 45 million ounces (TanzaniaInvest, 2026). Production is concentrated at Geita (AngloGold Ashanti) and at North Mara and Bulyanhulu (the Barrick/Twiga JV). Refining is now partially domestic: the Mwanza Precious Metals Refinery (opened 2021, a STAMICO JV) is rated at 480 kg/day to 99.99% purity, with Geita and Dodoma refineries added, though none is yet LBMA-accredited — Geita is reported on an RMI path toward accreditation "within 3–5 years". In gemstones Tanzania is the sole world source of tanzanite (Mererani Hills, ~14 km²), with rough and bead production of 83,014 kg in 2024 and reported exports of USD 19.2 m (Bank of Tanzania), yet the stone is largely exported raw — India re-exported roughly four times Tanzania's value (~USD 80 m, 2024) and only one value-addition centre operates in the Arusha/Manyara area; reserves are widely cited at ~50 million carats but are finite, with a depletion horizon commonly placed at 2040–2050. Diamond output was about 373,000 carats in 2024 from the Williamson mine (Shinyanga), against reserves of ~51 million carats.
Beneath the producing precious segment sits a deep but pre-processing critical-minerals pipeline. Graphite reserves of ~18 million t make Tanzania the world's ~5th-largest holder (USGS MCS 2025); production was ~25,000 t in 2024 (roughly doubled year-on-year), Lindi Jumbo (Walkabout, 40,000 t/yr capacity) began shipping concentrate to Europe in 2024, and a pipeline of Bunyu, Chilalo, Epanko, Mahenge and Nachu could reach ~530,000 t/yr by ~2026 (USGS FS2024-3029) — but there is no domestic spherical or processed graphite, only raw flake concentrate. Kabanga is one of the world's largest, highest-grade undeveloped nickel sulphide deposits, with Measured+Indicated ~46.8 Mt at 2.09% Ni plus copper and cobalt (Lifezone, Dec 2024); the July 2025 Feasibility Study declared maiden reserves at a first-quartile AISC of US$3.36/lb Ni net of by-products, with FID targeted for 2026 and a planned mine-to-metal chain feeding a Hydromet refinery at Kahama (Buzwagi SEZ) — pre-construction, with no production. Rare-earth reserves are ~890,000 t with the Ngualla project targeting ~37,000 t/yr but not yet producing; the Mkuju River uranium pilot plant ran in 2025 with full operations targeted 2026–29; Liganga iron ore and Mchuchuma coal remain long-stalled; and the Rukwa Basin holds exceptionally high-grade helium (surface seeps up to 10.4–10.6% He against a 0.3% commercial cutoff, certified prospective resources of 138–176+ Bcf), with the first helium mining licence issued in 2025 (Helium One, 480 km²) but pre-production. On energy, confirmed natural-gas reserves stand at ~57.54 TCF (TPDC), from Songo Songo (1974) and Mnazi Bay (~290 Bcf proved), with a proposed ~USD 42 bn LNG project (Shell, Equinor) still in Host Government Agreement negotiation and no FID; power capacity roughly doubled with the Julius Nyerere Hydropower Project (JNHPP) — 2,115 MW across nine turbines fully commissioned in 2025 (5,920 GWh/yr design) — from a pre-JNHPP base of ~1,900 MW (mix ~48% gas, ~31% hydro), materially relieving the historic energy constraint on heavy manufacturing while deepening hydro-dependence and drought-related reliability risk.
Agriculture supplies about a quarter of GDP and more than half of employment (World Bank, 2025) but is overwhelmingly raw at the point of export. Cashew output was 189,114 t in 2023 — world's ~8th and Africa's ~4th producer, ~20% of Africa's output — yet Agriculture Minister Hussein Bashe states that "only 5 percent of the raw cashew nuts are being processed locally with the other 95 percent being exported to Vietnam or India" (the Cashew Board of Tanzania puts local processing at "less than 20 percent"). Tobacco runs ~107,000 t (~8th-largest world producer), exported largely as raw leaf (~USD 500 m, OEC 2024); coffee (~55,000 t), tea (~36,000 t), sisal (~33,000 t; world's largest producer at independence), cloves (Zanzibar's signature spice) and cotton (Lake Victoria zone) are all largely exported raw or semi-processed, alongside one of Africa's largest cattle herds and Lake Victoria/Tanganyika fisheries. The one genuinely export-capable manufacturing sector is cement: production reached 10.9 Mt in 2024 against domestic demand of 8.5 Mt, generating a 2.43 Mt exportable surplus shipped to Rwanda, Malawi, Mozambique, Burundi, Uganda, DRC and Zambia (Minister Jafo, May 2025), from installed capacity of ~11 Mt/yr across ~13 plants — Tanzania Portland (Twiga, ~2.0 Mt/yr, Wazo Hill), Tanga Cement (Simba, ~1.3 Mt/yr), Dangote Mtwara (3.0 Mt/yr, ~500 Mt limestone reserves), Mbeya (Holcim) and Huaxin — with recorded exports climbing from 441,828 t (2021) to 632,726 t (2022) and then to the 2.43 Mt surplus in 2024. Industry accounts for about a third of GDP value-added but MVA per capita is low; other manufacturing (fertiliser, textiles, agro-processing, steel re-rolling) is limited, supported by SEZs/EPZs including the Benjamin Mkapa SEZ (Kigamboni) and the Buzwagi SEZ designated for the Kahama refinery.
Human capital is defined by a large, young labour force (median age ~18) with more than half employed in agriculture, a low tertiary and TVET base, dominant informal employment and underemployment, and thin advanced-manufacturing skill clusters; the mining sector employed ~310,000 in 2020. Infrastructure is the country's most distinctive enabler: Dar es Salaam port set a record throughput of 27.7 Mt in FY2024/25 (up from 23.69 Mt, ~15% growth, "a level not achieved since the port's inception"), handling ~93–95% of national trade and serving Zambia, Malawi, DRC, Burundi, Rwanda, Uganda and Zimbabwe, with transit cargo to landlocked neighbours of ~10.9 Mt (Jul 2025–Mar 2026, +32.6%) and container throughput rising from ~61,000 to ~102,000 TEU/month after the 2023 DP World private-operator reform; TPA targets 54.59 Mt by 2030/31. The electrified Standard Gauge Railway runs Dar–Morogoro–Dodoma for passengers (2024) and freight from 2025, designed for 160 km/h passenger service and up to 35 Mt/yr freight along the Central Corridor to Rwanda, Burundi and DRC, while TAZARA to Zambia's Copperbelt is under a ~USD 1.4 bn China-Zambia-Tanzania modernisation (30-year concession, 2025). This positions Tanzania as the Central Corridor logistics hub; on trade structure, total exports reached ~USD 11.9 bn in 2024 (up from USD 6.4 bn in 2019), led by gold ~USD 4.44 bn, with gold exports then jumping 37.4% to a historic USD 4.7 bn in 2025 — 45.7% of all goods exports.
Economic complexity & comparative advantage
Tanzania ranks 116th in the Atlas of Economic Complexity ECI ranking and has worsened 21 positions over the prior decade, a deterioration the Atlas attributes to a lack of export diversification even as it judges the country "as complex as expected for its income level" (Harvard Growth Lab, 2022 data, with the exact ECI numeric value and the newest 2024-data vintage unconfirmed). The Growth Lab's 2033 projection foresaw ~4.9% annual growth — top-decile globally — but driven more by population than by complexity gains, and OEC corroborates the low position (ECI −0.50, ~119th of 130, 2024 methodology). Revealed comparative advantage (RCA > 1) is concentrated in low-complexity primary and lightly-processed goods: gold, raw cashews, tobacco, coffee, cloves, sisal, cotton, tea and pulses (Estmann et al., The World Economy, 2022, RCA 2018; OEC 2024).
Within the product space, the Atlas flags diversification opportunities in agro-processing and processed foods (the highest-value near-term move), chemicals and pharmaceuticals (a long jump), plastics and rubber, construction-metal products, and textiles and apparel (for labour absorption). The trajectory is the concern a minister should register: complexity is stalling rather than accelerating, and projected growth leans on demographics more than on structural transformation.
The trump card · the single strongest continental position
Cement and construction materials (HS25) is the category where Tanzania best combines all five audit criteria — and, notably, it is not its biggest raw endowment. The decisive evidence is that the industry already operates as a net continental supplier: in 2024 Tanzania produced 10.9 Mt of cement against domestic demand of 8.5 Mt, generating a 2.43 Mt surplus that was exported to Rwanda, Malawi, Mozambique, Burundi, Uganda, DRC and Zambia (Minister of Industry and Trade, tabled May 2025). It holds the full input base — abundant limestone, with Dangote's Mtwara plant alone sitting on ~500 Mt (~149 years) — finished-product capability across roughly 13 plants (Tanzania Portland/Twiga ~2.0 Mt/yr at Wazo Hill, Tanga/Simba ~1.3 Mt/yr, Dangote Mtwara 3.0 Mt/yr, Mbeya/Holcim, Huaxin), and coastal logistics, with Dangote explicitly producing for sale "to surrounding overseas markets by sea". Recorded exports rose from 441,828 t in 2021 to 632,726 t in 2022 and then to the 2.43 Mt surplus in 2024, against installed capacity of ~11 Mt/yr. Newly abundant power — JNHPP's 2,115 MW commissioned in 2025 — removes the historic energy constraint on this energy-intensive industry, and AfCFTA models flag cement among the prime import-substitution and regional-value-chain categories.
The honest limits are equally clear. Cement is low-value and high-weight, so competitiveness is bounded by freight distance: Tanzania can credibly supply East and Central Africa and Indian Ocean markets, but not West or North Africa. Regional rivals compete on the same logic — Dangote operates in 10-plus countries and Egypt is a large exporter — and the surplus, while real, is modest relative to several neighbours' combined demand. The two runners-up carry their own caveats: refined gold rests on real and growing domestic refining (three refineries at 480 kg/day each) atop a leading African output and a 2025 export surge to USD 4.7 bn, but the refineries are not yet LBMA-accredited, capping premium-market access; and transit and logistics services — Dar es Salaam at 27.7 Mt in FY2024/25, plus SGR and TAZARA — make Tanzania the Central Corridor gateway for six-plus landlocked states, a large and defensible regional supply of a service rather than a good.
