Executive takeaways

Review period: 12–18 October 2026.

  • Copper inventories have become geographically distorted: over 1.6 million tonnes are reportedly sitting in the United States after tariff speculation diverted metal away from other markets.
  • Gold Fields’ proposed US$27 billion Northern Star acquisition remains stalled, with resistance from the target and some Gold Fields shareholders.
  • A Belgian investigation concerning alleged laundering of DRC mining revenues raises additional counterparty and politically exposed person risks. The allegations remain unproven.
  • Gold ended the week down 0.7%, reinforcing the need for short quotation periods.
  • No consequential new cobalt, lithium or mining-law change was verified.

1. US copper stockpiling distorts global availability

Confirmed — 14 October 2026

Copper inventories in the United States reportedly exceeded 1.6 million tonnes following a surge in imports driven by the possibility of future US tariffs. Comex-approved inventories had risen approximately 750% since February 2025. The price advantage encouraging metal to move into the US narrowed to about US$310 per tonne. Possible refined-copper tariffs remain under discussion for 2027 and 2028.

What this could mean for Afrimet — analysis:

  • Compare US, LME and Chinese netback prices before committing DRC copper to any destination.
  • Evaluate freight, financing, warehousing and tariff exposure, rather than relying on headline buyer prices.
  • State clearly who carries tariff-change risk between signing and customs clearance.
  • A future release of US stocks could pressure regional premiums even without a major production change.

2. Gold Fields’ Northern Star proposal remains stalled

Reported — 16 October 2026

Gold Fields CEO Mike Fraser was in Australia promoting the proposed A$38.7 billion, approximately US$27 billion, cash-and-share acquisition of Northern Star Resources. Northern Star reportedly wants a higher offer before entering formal talks. Gold Fields’ share price had fallen about 17% since the proposal. Gold Fields has proposed an Australian listing for the combined group and estimates up to US$5 billion in post-tax synergies.

What this could mean for Afrimet — analysis:

  • Do not treat the merger as completed when evaluating future ownership, supply or partnership opportunities.
  • Gold-sector valuations remain highly sensitive to long-term price assumptions.
  • Offtake, prepayment and service partnerships may carry less valuation risk than direct equity investment.

3. DRC mining-revenue investigation increases governance scrutiny

Confirmed investigation; allegations unproven — 15 October 2026

Belgian police searched properties connected to relatives and associates of DRC President Félix Tshisekedi as part of a money-laundering investigation reportedly linked to mining revenues. The investigation followed a complaint by Katanga-based civil-society organisations. The claims have not been adjudicated and the individuals targeted were not officially identified.

What this could mean for Afrimet — analysis:

  • Apply enhanced due diligence to intermediaries, beneficial owners and politically exposed persons.
  • Make payments only to verified contractual counterparties and matching legal-name bank accounts.
  • Retain auditable records covering mining title, mineral origin, royalties, export authority, beneficial ownership and commissions.
  • Avoid undocumented facilitation arrangements.

4. Lobito Corridor remains a financing opportunity, but no new commitment yet

Confirmed — 16 October 2026

Africa Finance Corporation said it was seeking further African mining investments and remained involved in developing the US-backed Lobito Corridor, intended to connect DRC and Zambian mines to Angola’s Atlantic port. AFC said investment announcements could follow within six to twelve months, but it did not announce a new DRC copper, cobalt, gold or lithium commitment during the review period.

What this could mean for Afrimet — analysis:

  • Develop a corridor-ready proposal covering verified mineral supply, aggregation, inland transport and export logistics.
  • Begin discussions with financiers and logistics operators before individual tenders emerge.
  • Compare Lobito with southern and eastern routes using total delivered cost, reliability and transit time.

5. Gold loses ground amid interest-rate uncertainty

Confirmed — 16 October 2026

Spot gold traded near US$4,165.12 per ounce and was headed for a weekly decline of approximately 0.7%. Strong inflation data and uncertainty over further US interest-rate increases weighed on the market.

What this could mean for Afrimet — analysis:

  • Keep gold offers valid for short periods, preferably 24 hours or less in volatile markets.
  • Use a clearly defined benchmark, timestamp and purity adjustment.
  • Avoid large fixed-price commitments without matching inventory or a hedge.
  • Use conservative price assumptions for supplier prepayments.

No consequential new development verified

  • DRC cobalt: no new export-quota allocation, major offtake or material production announcement.
  • DRC lithium: no substantive Manono financing, licence resolution, construction decision or binding offtake.
  • South African lithium: no new mine-development or processing milestone.
  • South African copper: no material domestic project or supply update.
  • Mining regulation: no new mining-code, royalty or export-rule change affecting the four focus minerals.
  • South African gold production: no sufficiently consequential project-level change identified.
