✔ How This Model Protects Your Investment
● Physical verification before payment — your representative personally sees and inspects the tin concentrate stockpile in Jos before any funds are committed.
● Independent laboratory verification before payment — an accredited lab of your choice confirms the Sn grade before you release a single dollar. No payment based on seller's documents alone.
● Zero payment if specification not confirmed — if the laboratory test report does not meet the agreed Sn grade specification, your payment obligation does not arise. Zero financial exposure before verification is complete.
● Confidence in our product — this buyer-first model is only commercially sustainable because we are confident in the consistency and quality of our Nigerian tin concentrate supply from the Jos Plateau belt.
What Is Tin Concentrate (Cassiterite)?
Cassiterite (SnO₂) is the primary ore mineral of tin — a tin oxide mineral with up to 78.6% Sn content in pure form, though commercial tin concentrates grade between 40% and 75% Sn depending on the degree of beneficiation and the composition of the feed ore. Cassiterite occurs as brown to black, adamantine-lustre tetragonal crystals, typically found as an accessory mineral in granitic pegmatites and hydrothermal veins, and concentrated by weathering and alluvial placer processes into commercially mineable alluvial and eluvial deposits.
The Jos Plateau region of Plateau State, Nigeria, is one of the world's most historically significant cassiterite-producing environments. The same granitic and rhyolitic geology that gives the Plateau its rugged topography is responsible for the extensive tin mineralisation that made Nigeria one of the world's leading tin producers during the peak of the colonial and post-colonial mining era (1910s–1960s). Today, artisanal and small-scale mining (ASM) operations across the Jos Plateau continue to produce significant quantities of alluvial cassiterite concentrate, which Augustina Impex Limited aggregates, quality-controls, and exports to international smelter and refinery customers.
Cassiterite from the Jos Plateau typically occurs in alluvial and eluvial placer accumulations derived from the weathering and erosion of the underlying tin-granites and younger granites (bimodal igneous suite) that dominate the Plateau's geology. The alluvial cassiterite is recovered by artisanal miners using traditional gravity methods (manual panning, sluicing) and increasingly by small mechanised operations using trommel screens, jig concentrators, and sluice box circuits.

Nigeria's Jos Plateau — Africa's Premier Tin Heritage District
The Jos Plateau is Nigeria's most historically significant mining district and one of Africa's great tin provinces. Commercial tin mining on the Plateau began under British colonial administration in the early 1900s, with mechanised dredge and monitor mining operations transforming the Plateau's river valleys by the 1920s and 1930s. At its colonial-era peak in the 1940s and 1950s, Nigeria was among the world's top three tin producers — with the Jos Plateau alone accounting for a major share of global cassiterite supply. The Plateau's tin-granites and younger granites (Pan-African age) host a remarkable concentration of cassiterite mineralisation in hydrothermal veins and in the alluvial and eluvial placer deposits derived from their weathering. Today, the Jos Plateau remains an active mining district, with artisanal and small-scale mining (ASM) operations producing cassiterite concentrate continuously — making Augustina Impex Limited's headquarters in Jos the natural centre for Nigerian tin concentrate aggregation and export.
Industrial Applications of Tin & Tin Metal
Tin derived from cassiterite concentrate smelting has applications across a remarkably diverse range of industries. The following are the primary end-use sectors that drive global tin demand:
Lead-Free Solder (Electronics)
The largest tin end-use globally — tin-silver-copper (SAC) lead-free solders used in printed circuit board (PCB) assembly for smartphones, computers, automotive electronics, and consumer devices. The global transition from leaded to lead-free solder (driven by EU RoHS directive) dramatically increased tin demand in electronics manufacturing.
Tinplate — Food & Beverage Packaging
Tin-coated steel sheet (tinplate) is used for food cans, beverage cans, aerosol cans, and general packaging. The thin tin coating provides corrosion resistance, prevents food contamination, and enables hermetic sealing — making tinplate one of the world's most important packaging materials. This is the second-largest tin end-use by volume.
Tin Chemicals & PVC Stabilisers
Organotin compounds (dibutyltin, octyltin, methyltin) are used as heat stabilisers in PVC plastic processing — preventing thermal degradation during pipe, profile, and film extrusion. Inorganic tin compounds (stannous chloride, stannic oxide) are used in glass coatings, electroplating, and specialty chemical applications.
⚙
Bronze & Brass Alloys
Bronze (tin-copper alloy, typically 5%–20% Sn) is one of humanity's oldest engineered materials, still widely used today in bearings, bushings, gears, marine hardware, architectural fittings, bells, and sculptures. Tin improves the hardness, corrosion resistance, and castability of copper alloys significantly.
Float Glass Manufacturing
The float glass process — used to produce all modern flat glass for windows, automotive, and architectural applications — uses a molten tin bath as the forming surface on which molten glass flows to create a perfectly flat sheet. Every pane of float glass in the world is produced over a tin surface.
Soldering & Brazing Alloys
Beyond electronics, tin-based solder alloys are used in plumbing (copper pipe jointing), automotive radiator manufacturing, HVAC system assembly, and electrical cable termination. Tin-silver and tin-bismuth specialty brazing alloys serve high-temperature industrial joining applications.
Indium-Tin Oxide (ITO) — Display Technology
Indium-tin oxide (ITO) is the transparent conducting coating used on LCD and OLED display touchscreens, solar cell front contacts, and flat panel displays. ITO films require high-purity tin oxide (SnO₂) as a co-constituent with indium oxide. As display manufacturing grows, ITO remains a niche but high-value tin application.
⚡
Lithium-Ion Battery Anodes
Tin-based anode materials (Sn, SnO₂, Sn alloys) are under active development and commercial adoption as next-generation lithium-ion battery anode materials, offering significantly higher theoretical lithium storage capacity than the graphite anodes dominant today. This represents an emerging, potentially significant future tin demand growth driver.

❓ Frequently Asked Questions — Nigerian Tin Concentrate
Q1. What Sn grade is the tin concentrate available in?
Our Nigerian tin concentrate (cassiterite) from the Jos Plateau is available with Sn content of 40%–70%, across three broad tiers: Premium Grade (Sn 60%–70%, hand-sorted high-grade concentrate), Standard Grade (Sn 50%–59%, the most commonly available grade from Jos ASM supply), and Lower Grade (Sn 40%–49%, suitable for upgrade or blending). The precise Sn grade of any specific lot is confirmed by independent laboratory assay during the buyer's pre-payment inspection process.
Q2. Do I have to pay any money in advance before inspecting the material?
Absolutely not. Our tin concentrate is offered exclusively on a pay-after-inspection basis. Your representative physically visits the warehouse in Jos, draws samples, submits them to an accredited independent lab, and payment is only released after you receive and accept the laboratory Sn grade confirmation. There is zero financial commitment required before this process is complete. This is our standard, non-negotiable commercial structure for tin concentrate sales.
Q3. Why is the Jos Plateau significant for tin production?
The Jos Plateau in Plateau State, Nigeria, has been commercially mined for tin (cassiterite) since the early 1900s under British colonial administration, making it one of Africa's longest-established and most historically significant tin-producing regions. At its colonial peak in the 1940s–1950s, Nigeria was among the world's top three tin producers. The Plateau's tin-granite geology continues to host extensive cassiterite mineralisation in alluvial and eluvial placer deposits being actively worked by artisanal and small-scale mining operations today.
Q4. What is cassiterite and how is it processed into tin metal?
Cassiterite (SnO₂) is the primary tin ore mineral — a tin oxide mineral containing up to 78.6% Sn in pure form. Tin concentrate (cassiterite at 40%–70% Sn) is processed into tin metal by smelting in a reverberatory or electric arc furnace, where the cassiterite is reduced to tin metal by carbon (coke) at temperatures above 1,200°C. The resulting crude tin metal is then refined electrolytically or by fire refining to produce standard grade tin metal (≥99.85% Sn) or high-purity tin (≥99.99% Sn) for electronics applications.
Q5. Is Nigerian tin from Jos Plateau conflict-free?
Yes. Tin from Augustina Impex Limited is sourced from licensed Nigerian mining operations in Plateau State — a federal state within a functioning national regulatory framework, governed by the Nigerian Minerals and Mining Act 2007 and regulated by the Federal Ministry of Mines and Steel Development (FMMSD). This is fundamentally different from conflict-affected tin supply originating from artisanal mining in the Democratic Republic of Congo and neighbouring regions, which carries significant “conflict minerals” ESG and supply chain due diligence obligations under Dodd-Frank Section 1502, EU Conflict Minerals Regulation, and equivalent frameworks.
Q6. Which laboratory should I use for the pre-payment assay?
You may nominate any internationally accredited mineral assay laboratory of your choice — SGS, Bureau Veritas, CCIC, ALS, Intertek, or any equivalent facility. We do not restrict your choice of testing laboratory. Your representative draws samples during the warehouse visit and arranges submission directly to your chosen lab. Both parties receive the test report simultaneously for complete transparency.
Q7. Are co-product minerals (coltan, wolframite) available alongside tin concentrate?
Yes. Nigerian tin mining operations on the Jos Plateau frequently produce coltan/tantalite (Nb₂O₅ + Ta₂O₅) and wolframite (WO₃) as co-product minerals alongside cassiterite, reflecting the multi-mineral pegmatite character of the Jos Plateau's geology. Augustina Impex Limited can supply these associated minerals alongside tin concentrate, offering buyers the convenience of multi-mineral procurement from a single trusted Nigerian source. Contact us to discuss co-product availability alongside your tin concentrate enquiry.
Q8. What export documentation comes with a tin concentrate shipment?
Every tin concentrate export from Augustina Impex Limited is accompanied by: Independent Laboratory Test Report (buyer's nominated accredited lab), Nigerian Export Supervision Scheme (NESS) Certificate, NEPC Export Certificate (RE No. 0039421), Commercial Invoice, Packing List, Certificate of Origin, Form NXP, and Bill of Lading — a complete, internationally bankable documentation package for every consignment.
Q9. What is the minimum order quantity for tin concentrate?
The minimum order quantity is confirmed at the Soft Corporate Offer (SCO) stage, based on the current stockpile availability in our production partner's warehouse at the time of enquiry. Augustina Impex Limited aggregates cassiterite concentrate from multiple artisanal and small-scale mining (ASM) operators across the Jos Plateau, which allows us to consolidate smaller production batches into commercially viable export volumes. Contact us with your target volume and we will confirm current availability in the SCO.
Q10. How quickly can we proceed from SCO to first shipment?
Timeline from SCO acceptance to first shipment depends on your representative's travel logistics to Jos and the laboratory turnaround time for the Sn assay. A standard Sn assay typically takes 3–7 business days at an accredited laboratory in Nigeria. Subject to satisfactory inspection results, payment clearance, and export documentation processing (NESS, NEPC), first shipment can typically be completed within 2–4 weeks from SCO acceptance for stockpiled material.
