A 285-hectare concession in Guma LGA, Benue State.
A Certificate of Occupancy holding backed by a Nigerian Ministry of Mines lease valid through 2043.
Interim resource estimate: greater than 1.6 million tonnes, established over less than 10% of the licensed area. Substantial exploration upside remains across the balance of the concession.
- Lead (Pb)Primary
- Zinc (Zn)Primary
- Barite (BaSO₄)High-purity, separately marketable
- Copper (Cu)Minor
Gold is present only in trace concentrations (<0.01 g/t) and is not a commercial component of this deposit.
Four independent laboratories. Three countries. 2018–2025.
Grades presented on a two-tier basis so counterparties can assess the deposit accurately — selective specimens alongside representative run-of-mine composites.
Targeted high-grade samples
Hand-selected mineralized material representing peak mineralization.
| Sample | Grade |
|---|---|
| Galena (Pb) | ~86–89% Pb |
| Sphalerite (Zn) | ~66% Zn |
| Barite (BaO) | ~57% BaO |
Run-of-mine composite
NGSA, 2025. Representative of typical bulk mined material.
| Constituent | Grade |
|---|---|
| PbO | 7.27% |
| ZnO | 0.25% |
| BaO | 6.40% |
Targeted samples confirm the presence and purity of high-grade mineralization; run-of-mine composites represent typical bulk-material grades. Both are shown so buyers can assess the deposit accurately.
Active excavation and material recovery on-site since 2008.
Heavy equipment mobilised on-site. Drilling programme delivering labelled, chain-of-custody core samples.
- ▸Active open-pit excavation with mobilised heavy equipment
- ▸On-site core drilling programme with labelled sample custody
- ▸Continuous material recovery since 2008
- ▸Trained local workforce, community-anchored operations
- ▸On-site stockpile management and pre-shipment aggregation
- ▸Constructed access-road corridor into the pit
An established FOB delivery corridor to Onne Port.
Weighing and sampling supervision at load port by Bureau Veritas / SGS, per industry-standard methodology. Chain-of-custody documentation issued for every shipment.
Access roads, on-site handling infrastructure and the port-logistics chain are in place and operational. Trucking corridor to Onne is well established.
Structured for international offtake.
The operation is structured for base-metals offtake with international counterparties — FOB delivery, LME-referenced pricing, independent inspection, and standard trade-finance instruments. Counterparty details are shared under NDA in the data room.
Three commodities, three distinct demand pools.
Battery manufacturing drives roughly 58% of global demand — automotive SLI, industrial UPS, telecom backup and grid-scale storage. Lead-acid remains the world's most recycled consumer product.
Galvanizing, die-casting and alloys. Essential to construction and automotive steel. Pricing referenced to LME zinc.
API-grade barite serves the oil & gas drilling sector — a separate, premium market providing revenue diversification independent of base-metal cycles.
The Benue Trough is a significant African lead–zinc corridor. Nigeria's 2020–2030 mining-sector reform agenda encourages private solid-minerals investment as economic diversification — a supportive policy environment for compliant, export-oriented operators.

Long-term extraction alongside long-term community impact.
A measured, forward-looking programme of sustainable development around the operation, including a planned mixed-use estate, pursued in step with the concession's remaining lease term.
Begin due diligence.
Serious counterparties engage in two stages. First, request access to the document data room — licenses, laboratory reports, offtake documentation and corporate records. Then, subject to signed NDA, we open technical and commercial discussions.
