Critical Minerals in Nigeria: Complete Guide to Lithium, Tin, Tantalum, Niobium and Rare Earths

By Kolawole King, CEO — Augustina Impex Limited | Published: August 2026 | 20 min read

The global race for critical minerals has fundamentally changed how governments, manufacturers, and investors look at Africa — and Nigeria in particular. As the world’s demand for electric vehicles, renewable energy infrastructure, semiconductor devices, defence systems, and high-technology consumer electronics continues to climb at rates that few analysts predicted a decade ago, the raw material base needed to sustain that growth is coming under intense scrutiny. Lithium for batteries. Tin for solder. Tantalum and niobium for capacitors and superalloys. Rare earth elements for permanent magnets and catalysts. These are no longer marginal industrial commodities — they are the foundational inputs of the modern economy, and their geography of supply is being redrawn in real time.

Nigeria sits at the centre of this redrawn map. Endowed by geology with exceptional deposits of lithium-bearing pegmatites, vast alluvial tin fields, significant columbite-tantalite (coltan) occurrences, rare earth mineralisation in bastnasite and monazite form, and a supporting cast of industrial minerals that rounds out one of Africa’s most diverse critical mineral portfolios, Nigeria offers international buyers something rare: a single-country source for multiple critical mineral feedstocks, within a democratic governance framework, under a maturing regulatory system, and at a stage of development where entry pricing is still attractive.

This guide provides a comprehensive overview of Nigeria’s critical mineral landscape — what is available, where it is found, what grades are achievable, how export is structured, and how international buyers can access verified, documented supply. It is written for procurement managers, mineral traders, investment analysts, and sustainability officers who need reliable, current information on Nigerian critical minerals sourced from direct market experience.

What Are Critical Minerals? The Global Policy Context

The term “critical mineral” has specific meaning in policy and procurement contexts — it refers to minerals that are economically significant, face supply concentration risks (often dominated by one or two producing countries), and are essential inputs for clean energy technologies, advanced manufacturing, or national security applications. Different jurisdictions publish their own critical minerals lists, and there is considerable overlap across the major frameworks:

Nigeria produces — or has commercially significant deposits of — minerals that appear on every major critical minerals list. This is not a coincidence of policy: it reflects Nigeria’s genuine geological endowment, rooted in the country’s position within the West African Craton, the Pan-African orogenic belt, and the younger Jos Plateau volcanic complex that hosts one of Africa’s most mineralogically diverse surface terrains.

Nigeria’s Geological Endowment: Why This Country Is So Mineralised

Nigeria’s extraordinary mineral wealth derives from three principal geological settings, each of which produces a distinct suite of critical minerals:

① Pan-African Pegmatite Belt (600–500 Ma) — A network of granitic pegmatite intrusions running through Kaduna, Kogi, Nasarawa, Ekiti, Cross River, Kwara, and Ogun states. Pegmatites are the primary host for lithium minerals (spodumene, lepidolite, kunzite), tantalum-niobium (columbite-tantalite), beryl, feldspar, and mica. Nigeria’s pegmatite belt is one of the most extensive in West Africa and has been a source of columbite — the niobium-bearing mineral — since the colonial era.

② Jos Plateau Younger Granites and Alluvial Fields (160–140 Ma) — The Jos Plateau was formed by Jurassic-age younger granites that weathered over millions of years to produce the alluvial tin-cassiterite, zircon, columbite, and rutile/ilmenite deposits for which Plateau State is famous. The HMS (heavy mineral sands) processing plant in Jos exploits this geological legacy, recovering multiple valuable mineral products from the same alluvial material using gravity, magnetic, and electrostatic separation.

③ Precambrian Basement Complex — The ancient basement rocks underlie much of central and northern Nigeria and host diverse mineral deposits including rare earth-bearing carbonatites (bastnasite), lead-zinc in carbonate sequences (Benue Trough), gold and iron ore occurrences, and phosphate deposits. The bastnasite rare earth carbonate deposits in Plateau State and adjoining areas are among the most geologically interesting rare earth occurrences in West Africa.

① Lithium — Nigeria’s Emerging Battery Minerals Powerhouse

Lithium is the foundational element of the modern battery economy — the key constituent of lithium-ion batteries that power electric vehicles, grid-scale energy storage, smartphones, laptops, and an expanding universe of consumer electronics. Global lithium demand is projected to grow by 300–500% between 2025 and 2040, driven overwhelmingly by EV adoption in China, Europe, and North America. This demand trajectory has made new lithium supply sources — particularly in Africa, which is rapidly emerging as the continent of the next lithium boom — a critical priority for battery manufacturers and chemical processors alike.

Nigeria’s lithium resources are primarily hosted in spodumene and kunzite pegmatites — the same mineral type that dominates the hard rock lithium supply from Australia, which currently provides approximately 50% of global lithium concentrate supply. Nigerian spodumene has been known to geologists for decades, but serious commercial evaluation has accelerated dramatically since 2020, as elevated lithium prices and supply concentration concerns directed exploration capital towards West Africa.

Nigerian spodumene is sold in run-of-mine (ROM) lump and crushed form — not as refined lithium carbonate or hydroxide, which requires chemical processing infrastructure that is not yet present in Nigeria at commercial scale. The commercial pathway is therefore: Nigerian spodumene concentrate (Li₂O 4%+, achieved through gravity and flotation beneficiation) → export to lithium chemical processors in China, South Korea, Finland, or Portugal → conversion to battery-grade Li₂CO₃ or LiOH → battery cathode manufacturing.

Lepidolite, sourced from Auchi, Edo State, is an alternative lithium mica mineral increasingly valued by processors who can handle its more complex mineralogy. Ex-Works pricing from Auchi is structured by Li₂O grade: ₦150,000/MT for 1.2–1.5% Li₂O material, ₦180,000/MT for 1.5–2.0% Li₂O, and ₦230,000/MT for the highest 2.0–2.5% Li₂O fraction.

② Tin (Cassiterite) — The Jos Plateau Legacy and Modern Supply

Tin may be the mineral most historically associated with Nigeria — the Jos Plateau was one of the British Empire’s most productive tin-mining regions in the first half of the twentieth century, and the tin boom that followed colonial discovery transformed the economic and demographic landscape of what is now Plateau State. At peak production in the 1960s, Nigeria was among the world’s top five tin producers. While production volumes have declined from those colonial highs, the geological resource base remains substantial, and the combination of alluvial accessibility, established processing infrastructure, and growing global tin demand is driving a meaningful revival of the Nigerian tin sector.

Tin’s role in modern industry is more important than ever. Solder — the primary use of refined tin — is the key joining material in every printed circuit board, semiconductor package, and electronic assembly produced anywhere in the world. There is no commercially viable substitute for tin solder in electronics manufacturing. As the global electronics industry expands — driven by AI hardware, EV electronics, IoT devices, and 5G infrastructure — tin demand grows proportionally. The International Tin Association (ITA) has repeatedly flagged concerns about medium-term supply adequacy, making diversified tin sourcing a strategic priority for electronics procurement teams.

The Jos HMS plant — operated by Augustina Impex’s partner Eliezer Onah — processes alluvial heavy mineral sands from the Jos Plateau to produce: cassiterite concentrate (Sn 60%+), zircon sand (ZrO₂ 40–66.5%), columbite concentrate (Nb₂O₅ bearing), ilmenite, and rutile — making it a multi-product operation that delivers exceptional economic efficiency per tonne of alluvial material processed.

③ Tantalum and Niobium — Nigeria’s Coltan Heritage and 21st Century Demand

Tantalum and niobium are among the most technologically critical minerals in modern industry, yet they remain little known outside the specialist minerals community. Understanding their applications helps explain why demand is growing and why Nigeria’s coltan deposits are commercially significant.

Tantalum (Ta) is primarily used in the manufacture of tantalum capacitors — miniature, highly efficient capacitors found in virtually every modern electronic device: smartphones, tablets, laptops, hearing aids, pacemakers, automotive ECUs, and military electronics. Tantalum capacitors are preferred for their superior electrical performance in high-frequency, high-reliability applications. There is no commercially viable equivalent substitute for tantalum capacitors in demanding applications, making tantalum supply security a strategic priority for electronics manufacturers. The global supply base for tantalum is highly concentrated — the DRC and Rwanda together supply the majority of artisanal tantalum, while Australia (Wodgina, Greenbushes) provides most of the large-scale hard rock supply. Nigerian tantalum offers a geopolitically diversified alternative from a non-CAHRA source country.

Niobium (Nb) is dominated — uniquely among critical minerals — by a single country: Brazil accounts for approximately 90% of global niobium supply, primarily through CBMM’s Araxá carbonatite deposit. Niobium’s primary market is high-strength low-alloy (HSLA) steel production: a small addition of niobium (0.03–0.05%) dramatically increases steel strength, allowing lighter structural components in vehicles, pipelines, ships, and buildings. Niobium is also used in superalloys for jet engines and gas turbines, and in niobium-doped lithium-ion battery cathode materials being developed for faster-charging EV applications.

Nigerian coltan is a mixed mineral — columbite-tantalite — that contains both niobium (as Nb₂O₅ in columbite) and tantalum (as Ta₂O₅ in tantalite). The ratio of Nb to Ta determines which metal predominates and therefore which market the material primarily serves. Augustina Impex sources two commercial coltan grades from Nigeria’s pegmatite belt:

Supply capacity is 60 MT per month, with loading at Lekki Deep Sea Port, Lagos. Inspection is by Bureau Veritas or CCIC at Lekki Port. Payment terms: 60% advance T/T after Supply and Purchase Agreement (SPA) signing, with the remaining 40% payable against the CCIC quality inspection report at Lagos port. Duration of supply: 12-month agreements with roll and extension options.

Nigeria has a long history in the columbite trade — columbite (the niobium-dominant member of the columbite-tantalite series) was one of Nigeria’s first commercial mineral exports. The name “columbium” — an alternative historical name for niobium, still used in the US steel industry — reflects the significance of the Nigerian deposits in the early history of this element’s commercial development. Modern Nigerian coltan supply comes primarily from artisanal and small-scale mining in Kaduna, Nasarawa, Kogi, and Cross River states, with the best grades typically from the Jurassic-age pegmatites of the central belt.

④ Rare Earth Elements — Nigeria’s Emerging REE Position

Rare earth elements (REEs) are a group of 17 elements — the 15 lanthanides plus scandium and yttrium — that are critical inputs for permanent magnets (neodymium-iron-boron magnets used in EV motors and wind turbines), catalytic converters, phosphors, glass polishing, and a wide range of high-technology applications. The global REE market is dominated by China, which controls approximately 60% of mining and 85% of processing, creating significant supply chain vulnerability for manufacturers outside China. Diversification of REE supply chains has become a strategic priority for the EU, US, Japan, and South Korea — and Africa is increasingly recognised as a potential alternative source region.

Nigeria’s REE mineralisation occurs in two principal forms:

Bastnasite — Light Rare Earth Carbonate

Bastnasite (RECO₃F) is a fluoro-carbonate mineral that is the world’s most commercially important rare earth ore — the Mountain Pass deposit in California and the Bayan Obo deposit in China, both bastnasite deposits, have historically provided the majority of global REE supply. Nigerian bastnasite deposits, developed and produced by Tulay Africa (Augustina Impex’s Bastnasite production partner in Victoria Island, Lagos), carry total rare earth oxide (TREO) values across a range of grades from multiple pit samples — including alluvial and hard rock occurrences assayed by Zirconex Mining and Metal Laboratory (ISO/IEC 17025 accredited, Abuja). The key REE components in Nigerian bastnasite include cerium (Ce), lanthanum (La), praseodymium (Pr), neodymium (Nd) — the economically most valuable NdPr fraction that drives permanent magnet demand.

Monazite Sand — Light REE Phosphate with NdPr and Low Thorium

Monazite ((Ce,La,Nd,Th)PO₄) is a phosphate mineral that concentrates in heavy mineral sand deposits alongside ilmenite, zircon, and rutile. Nigerian monazite — recovered from the Jos Plateau HMS processing operations — carries a highly attractive specification: TREO 52.2%, NdPr 12.0%, ThO₂ approximately 0.05%. This ultra-low thorium content is a critical commercial advantage: most monazite deposits carry ThO₂ values of 3–8%, which triggers NORM (naturally occurring radioactive material) classification requiring specialised handling, permitting, and regulatory compliance in importing countries. Nigerian monazite’s 0.05% ThO₂ content places it at the extreme low end of the global monazite spectrum — significantly reducing the regulatory and handling burden for importers, particularly in the EU where NORM import procedures are complex.

⑤ Supporting Critical Minerals: Copper, Zinc, Fluorite, Tungsten, Graphite and Zircon

Beyond the headline critical minerals, Nigeria’s mineral portfolio includes several additional commodities that appear on major critical minerals lists or serve critical industrial supply chains:

Nigeria’s Regulatory Framework for Critical Mineral Exports

Nigeria’s solid mineral export sector is governed by a comprehensive regulatory framework that provides the governance and documentation infrastructure needed for international buyers to import Nigerian minerals within their legal compliance requirements:

① Federal Ministry of Mines and Steel Development (FMMSD) — The primary regulatory authority for the Nigerian mining sector. Licenses mineral title (Exploration Licence, Mining Lease, Small-Scale Mining Licence), oversees mining operations compliance, and administers the Mining Cadastre Office (MCO) that manages Nigeria’s electronic licence register.

② Nigerian Export Promotion Council (NEPC) — Registers all solid mineral exporters (RE number), issues Certificates of Origin for export shipments, and maintains the national export promotion infrastructure. Augustina Impex’s export entity (Jase Odus Nigeria Limited) holds NEPC RE Number 0039421 (valid through July 2027).

③ Nigerian Export Supervision Scheme (NESS) — Issues shipment-level export compliance certificates for all solid mineral export lots. The NESS certificate is a mandatory export document and provides the shipment-specific traceability that buyers need for supply chain due diligence records.

④ Nigerian Nuclear and Radiological Regulatory Authority (NNRA) — Issues NORM (Naturally Occurring Radioactive Material) export permits for minerals that carry radioactive elements above threshold levels. Monazite sand exports require NNRA compliance — Augustina Impex coordinates NNRA permitting for all monazite shipments. Bastnasite at typical Nigerian grades generally does not require NNRA permitting.

⑤ Nigerian Customs Service — Administers HS code classification and customs clearance for export shipments. Form M (import declaration) is completed by the buyer’s bank in the importing country for payment and import documentation purposes.

The Critical Mineral Export Process: Step by Step

① Specification Confirmation — Buyer confirms mineral type, grade requirements, quantity, incoterms, and required documentation package.

② Soft Corporate Offer (SCO) — Augustina Impex issues a commercial SCO within 48 hours of receiving confirmed buyer specifications. The SCO covers price, quantity, quality, incoterms, payment terms, inspection, and validity period.

③ Sample Shipment — For buyers requiring independent laboratory verification, sample lots (100kg–500kg) can be dispatched for assay by the buyer’s nominated laboratory before the main commercial order is placed. Sample dispatch is via DHL for small quantities or via air freight for larger sample lots.

④ Supply and Purchase Agreement (SPA) — A formal commercial contract executed between Jase Odus Nigeria Limited (seller) and the buyer, covering all terms and conditions. The SPA is the trigger document for payment and production.

⑤ Production, Aggregation, and Processing — Mineral is aggregated, quality-checked, and processed (where HMS processing is applicable) to meet agreed specification.

⑥ Pre-Shipment Inspection — CCIC, SGS, or Bureau Veritas conducts independent quantity and quality verification at the agreed inspection point (mine, processing plant, or Lagos port). Inspection certificate issued.

⑦ Export Documentation and Shipment — Full export documentation package: NESS certificate, NEPC certificate, Certificate of Origin, Commercial Invoice, Packing List, and Bill of Lading or Airway Bill. For NORM minerals (monazite): additional NNRA export permit included.
