Ghana has won an arbitration over a US$196.5 million corporate income tax assessment against Tullow Oil, while the government puts the amount at US$393.09 million once the associated 100% penalty is included. Tullow reported US$300 million of liquidity headroom at 30 June. The arbitration has been decided. How the liability translates into cash leaving the company has not.

The four stories today sit at different points in the same chain. Once a resource has been found, control over value is shaped by who can tax the cash, where the commodity is processed, whether the project can legally reach construction and whether promised capital actually arrives.

Burkina Faso is moving directly into processing. RAFFINOR-BF, the country’s first national gold refinery, was commissioned on 28 September and refined its first bars. Its first phase has theoretical capacity of 164 tonnes a year. Published 2025 statistics put gross gold production at 100.692 tonnes, leaving the refinery already sized beyond current domestic output.

Kenya presents the opposite challenge. Dangote Industries has broken ground on a proposed US$16 billion, 700,000-barrel-per-day refinery at Lamu, but an interim court order protects the portions of the project land occupied by 133 petitioners. The ceremony could proceed. Clearing, excavation, fencing, demolition, construction, transfer or other interference with those occupied portions cannot simply proceed as if the litigation does not exist.

In Zambia, control has already changed. International Resources Holding’s Delta Mining owns 51% of Mopani Copper Mines, while state-controlled ZCCM Investments Holdings retains 49%. ZCCM-IH now alleges funding shortfalls, inadequate development expenditure and unapproved high-cost related-party and third-party debt. IRH says the partnership remains constructive.

The instruments are different. Ghana has an arbitral award. Burkina has an operating refinery with throughput still to prove. Lamu has a proposed refinery whose land and environmental interfaces remain live. Mopani has an executed investment agreement whose performance is being contested.

A licence gets a resource into the portfolio. Much of the value is determined afterwards.

An International Chamber of Commerce tribunal delivered its award on 29 September in Tullow Oil’s dispute with Ghana over business-interruption insurance proceeds received between 2016 and 2019.

The Ghana Revenue Authority issued the assessment in December 2022, and Tullow challenged it under its Ghana Petroleum Agreements.

Tullow says the tribunal found that the US$196.5 million corporate income tax assessment does not breach those agreements. It also says the tribunal ruled that the 100% penalty falls outside the scope of the contractual protections in the Petroleum Agreements.

Ghana describes the result more broadly. The Ministry of Finance says the tribunal upheld an assessment of US$393,091,993.70, found the penalty properly applied, rejected the limitation argument and upheld the GRA’s enforcement action. It credited the Attorney-General, the GRA and external counsel Foley Hoag LLP for the case.

Those formulations are not identical. If Tullow’s description captures the tribunal’s reasoning on the penalty, a finding that the Petroleum Agreements do not protect against it would not by itself decide every possible objection under Ghanaian tax law. Ghana’s account says the tribunal went further and found the penalty properly applied.

Without the award itself, that difference should remain visible. Any remaining domestic challenge would have to proceed through the applicable Ghanaian tax machinery, subject to the applicable procedural position, rather than through the Petroleum Agreement protection Tullow invoked in arbitration.

Tullow says it is disappointed and will consider its next steps after further engagement with Ghana.

Ghana and Tullow were already discussing outstanding tax matters before the award. Those talks now continue with Ghana holding an arbitral victory and Tullow operating Jubilee and TEN.

Tullow reported US$300 million of liquidity headroom at 30 June. Ghana’s stated US$393.09 million claim exceeds that figure. Full-year free-cash-flow guidance is US$170 million to US$250 million.

The Jubilee and TEN Petroleum Agreements now run to the end of 2040, and Tullow is acquiring the FPSO Prof. John Evans Atta Mills serving TEN for US$205 million gross. Tullow says its net share is approximately US$125.6 million. The company has not explained how that allocation relates to its disclosed 54.84% TEN interest.

The next useful disclosure is the collection structure.

Ghana has said implementation should preserve Tullow’s capacity to operate and invest. A US$393 million claim collected rapidly has a different effect from one spread across several years or otherwise accommodated around the investment programme.

Tullow defeated the US$320.3 million Branch Profit Remittance Tax claim in 2025. It has now lost the insurance-proceeds Petroleum Agreement argument. A separate US$190.5 million loan-interest dispute remains outstanding.

Fiscal protections do not operate as a general shield around the investment. Their value is revealed tax by tax, clause by clause and forum by forum.

Ghana now holds the award. Tullow remains central to the assets from which Ghana expects future production, gas and tax revenue.

Neither side maximises value by pretending the other is dispensable.

Burkina Faso commissioned RAFFINOR-BF in Ouagadougou on 28 September and refined its first gold bars.

The state holds 51% of the refinery company through the Société Nationale des Substances Précieuses, SONASP, alongside private investors. The plant represents more than CFA11 billion of investment. First-phase theoretical refining capacity is 164 tonnes a year, with a planned second phase taking theoretical capacity to 515 tonnes.

The latest published 2025 summary puts gross national gold production at 100.692 tonnes. It identifies 57.773 tonnes as industrial and 42.698 tonnes as artisanal production.

Those two components add to 100.471 tonnes, leaving 0.221 tonnes, or 221 kilograms, unreconciled in the headline breakdown. The ministry’s underlying statistical bulletin separately tracks semi-mechanised production and gold recovered from mining residues, but the annual summary does not specify how much of the 221 kilograms belongs to either category.

The artisanal figure alone represents about 42% of reported national production.

Burkina already has more control over potential feedstock than a comparison with private industrial mines suggests.

SONASP collected 29.56 tonnes of gold from artisanal, semi-mechanised and mining-residue sources by 30 September 2025.

The state also acquired the Boungou and Wahgnion gold mines in 2024 and subsequently transferred the assets to state mining company SOPAMIB.

Those assets are obvious potential sources of state-influenced refinery feedstock, but no evidence reviewed for this edition shows that their doré has been formally committed to RAFFINOR-BF.

IAMGOLD’s Essakane mine is currently 85% owned by IAMGOLD and 15% by Burkina Faso. Endeavour Mining owns 85% of both Houndé and Mana. Orezone operates Bomboré, while West African Resources operates Sanbrado and Kiaka.

Burkina has solved part of the physical-processing problem. It has not yet demonstrated the commercial model.

A refinery producing 99.99% gold still needs predictable feedstock, working capital, credible assay and settlement and international market access.

The artisanal flow is especially important because SONASP already sits closer to that gold than it does to the commercial decisions of every privately operated industrial mine. State ownership of Boungou and Wahgnion widens the potential controlled feedstock pool further.

The next question is therefore less whether Burkina Faso can physically refine gold and more how much gold it can economically direct through RAFFINOR-BF without making the domestic route less attractive than existing channels.

Correction: Our previous edition said the application was filed on Monday and described Suleiman Ali and Kanywa Kamunde as leading it. Subsequent court reporting records Justice Jane Onyango’s order as dated 25 September and styles the petition as Salim Tima Swale and 132 others; Ali and Kamunde are not reflected as named petitioners in the court record we have reviewed.

Dangote Industries has broken ground on its proposed US$16 billion Lamu refinery, designed for 700,000 barrels per day and accompanied by a proposed 1,000 MW power plant.

The Malindi Environment and Land Court did not stop the 30 September ceremony.

Its interim order is directed at the portions of LR No. 13061 occupied by the petitioners. The respondents are temporarily restrained from clearing, excavating, fencing, demolishing, constructing on, transferring, disposing of or otherwise interfering with those occupied portions pending the next hearing on 14 October.

That scope explains how the groundbreaking could proceed without extinguishing the restraint.

Two readings are in circulation. Counsel for the applicants interprets the order as meaning construction cannot begin before 14 October. Dangote says activities “may be affected.”

The project still has to connect its industrial ambition to legally usable land, environmental approvals, financing and crude supply.

Kenya does not currently produce commercial crude. A 700,000 bpd refinery therefore depends on regional and international feedstock as well as a market extending beyond Kenya.

There is a relevant Lamu precedent. In 2019, the National Environment Tribunal set aside the environmental licence for the proposed 1,050 MW Lamu coal power plant after finding defects in the EIA process, including public-participation failures, and required a fresh assessment if the project was to proceed.

The refinery is a different project, but the precedent shows why approvals around a major Lamu energy asset are part of the project itself, not paperwork outside it.

The groundbreaking is meaningful. It shows sponsor commitment and substantial political backing.

It does not establish financial close, resolve the land claims or authorise interference with the portions protected by the order.

For a US$16 billion project, the next milestones are documents and enforceable rights: the 14 October court process, land access, environmental approvals, committed financing, crude-supply contracts and major construction agreements.

Lamu has moved beyond announcement. It has not yet reached unrestricted execution.

ZCCM Investments Holdings has accused International Resources Holding’s Delta Mining of breaches of the agreements under which Delta acquired 51% of Mopani Copper Mines in 2024. ZCCM-IH retained 49%.

The original transaction contemplated up to US$1.1 billion of investment.

In its 18 September letter, first reported by Bloomberg on 28 September, ZCCM-IH alleges Delta’s 2025 payments were US$61 million below the minimum required and says it is unaware of transfers satisfying a US$140 million 2026 funding obligation.

It also alleges that only US$62.3 million of a US$308.1 million project-development budget had been spent by the end of March.

The governance allegation goes further than expensive borrowing. ZCCM-IH alleges unapproved high-cost related-party and third-party debt.

IRH says the partnership remains strong and constructive.

President Hakainde Hichilema met IRH chief executive Ali Rashed Alrashdi in Abu Dhabi on 28 September, the same week the dispute became public.

Hichilema described Mopani as important to Zambia’s three-million-tonne annual copper target and pressed for higher production while saying he was encouraged by progress at the mine.

Mopani produced just over 5,000 tonnes of copper cathode in June. Annualising one month is not a forecast, but it illustrates the scale gap: roughly 60,000 tonnes a year against IRH’s stated 300,000-tonne target for 2029, or about one-fifth of the target.

US$62.3 million against US$308.1 million remains the number to watch.

If ZCCM-IH’s account is correct, only about one-fifth of planned project-development expenditure had been deployed by the end of March.

The related-party debt allegation also changes the governance question. In a 51:49 venture, borrowing connected to the controlling shareholder can affect financing cost, cash priority and the minority shareholder’s economics even where headline capital commitments appear large.

Glencore controlled Mopani until 2021, when ZCCM-IH acquired it for US$1 upfront. Three years later, control moved again for new capital.

The asset has had enough ownership changes. Its next phase depends on execution of the bargain already signed.
