From titled ground.
To verified offtake.

Structured mineral trading for gold, copper cathodes, coltan, and silver; end-to-end exploration, mine development, and compliant sourcing across East Africa and the DRC.

01 — Commercial Offtake

Physical minerals trading with verifiable origin.

We execute institutional offtake mandates for international buyers and industrial processors. Origin, assay, and custody are established before the flight or vessel is named.

Gold

Au · 99.5%+

Dore bars and refined bullion under complete chain-of-custody documentation.

  • Origin: Kenya, Tanzania, Uganda & compliant DRC perimeters
  • Assay: Ministry laboratories, Alex Stewart, or Alfred H. Knight
  • Settlement: CIF named international refinery or bonded vault
  • No retail bullion or walk-in inquiries; commercial mandates only

Copper Cathodes

Cu · 99.99% Grade A

LME-grade cathodes produced from Zambian and DRC Copperbelt smelters.

  • Specification: Non-LME registered Grade A (ASTM B115)
  • Dimension: Approx. 914mm × 914mm × 12mm; bundled
  • Delivery: Ex-bonded warehouse (Kolwezi, Lubumbashi, Dar es Salaam)
  • Logistics: Bonded flatbed trucking and ocean breakbulk/FCL

Coltan & Tantalite

Ta2O5 · 25%–35%+

High-purity tantalite ore sourced under strict regional traceability frameworks.

  • Compliance: Full ICGLR certification & OECD Due Diligence Guidance
  • Origin: Certified green artisanal and commercial mine sites
  • Testing: XRF laboratory elemental assay before packaging
  • Transit: Steel drums sealed under ministry customs lock

Silver & Industrial

Ag · 99.9%

Refined silver ingots, byproduct anodes, and export-grade industrial scrap.

  • Specification: 99.9% fine silver bars and industrial ingots
  • Custody: Certified smelter assays attached to export permit
  • Also handling: Used rail (R50/R65) and secondary aluminium
  • Mode: Secured air passage or ocean container export

Offtake Architecture

The file moves before the cargo moves.

Every mineral mandate follows a rigorous sequence: title verification, counterparty KYC, laboratory assay corroboration, and customs flight/vessel booking. We eliminate counterparty ambiguity so title transfers cleanly without apron disputes.

  • Direct coordination between mine concessions, refineries, and trading houses
  • In-country assay inspection at points of aggregation
  • Escorted secure transit to international bonded zones

02 — Mining & Technical Services

Mine-to-market lifecycle solutions.

From initial geological prospect evaluation to commercial processing and export logistics, we assist concession owners and investors in structuring bankable operations.

Phase 01

Exploration

Geological mapping, geochemical sampling, core drilling supervision, and concession boundary demarcation across East Africa and the DRC.

Phase 02

Mine Development

Feasibility studies, mine layout engineering, equipment procurement, environmental impact filings, and local stakeholder community agreements.

Phase 03

Mineral Production

Beneficiation plant setup, crushing, gravity concentration, smelting, and in-field metallurgical extraction oversight.

Phase 04

Mine-to-Market

Connecting pit-head extraction to international refining contracts, export licensing, transit insurance, and secured air waybills.

03 — Sourcing Network

Verified supply channels across seven jurisdictions.

We bridge international offtakers with vetted in-country producers, ensuring ethical compliance, statutory validity, and reliable quantity delivery.

Sourcing Tier Counterparty Profile Verification & Governance Primary Output
Licensed Miners Commercial concessionaires holding active exploitation permits (PE/PML). Cadastre Minier (CAMI) verification, statutory tax clearance, environmental compliance. Gold dore, high-grade copper cathodes, tantalite ore.
Mining Cooperatives Artisanal mining cooperatives organized under formal ministerial charters. Artisanal mining zone (ZEA) registration, child-labour-free certification, cooperative audits. Alluvial gold, hand-sorted coltan, wolframite.
Mining Companies Established mid-tier and industrial mining operations. Full corporate KYC, annual audited accounts, international environmental social governance (ESG). Bulk copper cathodes, concentrated ores, refined bars.
Aggregators & Comptoirs Licensed buying houses with official export authorization and smelting infrastructure. Annual trading licence verification, anti-money laundering (AML) screening, export quotas. Aggregated gold lots, consolidated regional mineral parcels.
International Suppliers Global trading houses, secondary refiners, and multinational suppliers. Banking compliance, international sanctions screening, standardized Incoterms. Imported processing reagents, mining equipment, counter-trade lots.
