Solway Investment Group, a Swiss mining and metals investor whose Liberian subsidiary explored iron ore at Blei and Detton in Nimba County, says its work identified more than 1.4 billion tonnes of economically viable iron-ore resources. After seeking more than US$200 million in arbitration, it recovered US$314,619.47 for physical assets, plus interest.

The contrast is striking, but the 1.4 billion tonnes is Solway’s characterisation of an exploration-stage resource. The public material reviewed does not identify it as a reserve or a resource estimate reported under a recognised reporting code. Geological scale, technical confidence and legally protected value are different things.

A majority of a tribunal constituted under the UNCITRAL Arbitration Rules reportedly rejected compensation for Solway’s exploration licence and prospective mine value. Professor John Gotanda dissented, relying partly on documents showing that Liberia itself treated Solway’s rights as something requiring formal extinguishment before the ground moved to ArcelorMittal.

Tanzania presents the same problem further down the asset cycle. Aminex, a London-listed gas developer with a 25% non-operated interest in the Ruvuma production-sharing agreement, has preserved a December first-gas path at Ntorya after challenging operator ARA Petroleum Tanzania’s proposed development sequence.

At the producing Songo Songo gas field, tenure is moving the other way. Orca Energy’s current development licence expires on 10 October 2026. Orca is also trying to sell its Tanzanian business, but the Share Purchase Agreement allows any party to terminate for any reason. The purchasers were therefore never irrevocably committed to carry the unresolved licence risk. A separate 31 August transaction longstop has also passed. No later Orca announcement located through 26 September confirms either a further transaction extension or a Songo Songo licence extension.

At Zimbabwe’s Bikita lithium operation, Sinomine Resource is testing value after extraction through a new tantalum plant, lithium sulphate processing and additional niobium and caesium recovery.

The spectrum is useful. Solway asks what exploration tenure protects. Ntorya asks how development rights become revenue. Songo Songo shows that decades of production do not eliminate tenure risk. Bikita asks whether downstream capital actually creates more recoverable value.

Solway Investment Group, a Switzerland-based mining and metals investor, says exploration by its Liberian subsidiary at Blei and Detton identified more than 1.4 billion tonnes of economically viable iron-ore resources.

A majority of a tribunal constituted under the UNCITRAL Arbitration Rules has reportedly rejected the core of Solway’s claim after Liberia terminated its exploration rights and ArcelorMittal subsequently received rights over the disputed area.

Solway sought more than US$200 million. The tribunal found Liberia liable for taking physical assets and awarded US$314,619.47, plus interest, while rejecting the much larger claim attached to the exploration licence and prospective mine value.

The 1.4 billion-tonne figure requires qualification. It is Solway’s description of an exploration-stage resource. The public material reviewed does not identify it as a reserve or show classification under a recognised reporting code. A large exploration tonnage can support substantial economic expectations without being equivalent to a feasibility-tested, financeable mine.

Liberia EITI identifies Solway Mining Incorporated’s mineral exploration licence as MEL8000119, records an area of 55.8 square kilometres and shows an original three-year term ending in October 2022.

That area is approximately 5,580 hectares, broadly consistent with separate reporting placing the Blei concession around 5,574 hectares. A 222-hectare figure reported elsewhere remains an unexplained outlier.

The chronology after the original term is less clear. Liberian authorities have said a conditional extension was granted in 2022 but later lapsed following defaults. Reporting based on the arbitral award records a formal termination on 16 August 2023.

ArcelorMittal’s 2005 Mineral Development Agreement covered approximately 51,342 hectares, with mining rights over Tokadeh, Gangra and Yuelliton and exploration rights encompassing Blei and Detton. It argued that Solway had been granted rights over ground already protected by its agreement with Liberia.

On 29 June 2023, Liberia and ArcelorMittal entered a Deed of Settlement addressing third-party mineral rights inside the concession and contemplating the termination or extinguishment of Solway’s position.

The difference between Solway’s claimed 1.4 billion tonnes and the US$314,619.47 award exposes the distance between geological discovery and protected project value.

Solway had spent capital, generated geological information and entered negotiations for the Mineral Development Agreement required to progress towards production. The tribunal majority nevertheless appears to have concluded that prospective mine economics had not crystallised into a compensable right.

ArcelorMittal is much further down that chain. It inaugurated its new Tokadeh concentrator in June 2025 as the centrepiece of a US$1.8 billion Phase II expansion, increasing capacity from approximately 5Mtpa to 20Mtpa. Cumulative Liberian investment was about US$3 billion at inauguration and has subsequently been put at approximately US$3.5 billion.

The award forces investors to separate five things that easily collapse into one project valuation: the mineral endowment, the legal right to explore it, the technical confidence assigned to that endowment, the approvals still required to develop it, and the portion of accumulated value legally protected if the state intervenes.

Gotanda’s dissent makes the boundary harder.

According to reporting on the award, he relied on the June 2023 Deed of Settlement, a July settlement involving Solway and a September ArcelorMittal letter recording termination. In his view, those documents showed that Liberia itself treated Solway as holding rights that needed to be extinguished before transfer.

Uncertainty over whether Solway would obtain a Mineral Development Agreement could therefore justify a large discount to prospective mine value without necessarily meaning the existing investment had no compensable value beyond physical equipment.

For anyone financing, acquiring or taking a royalty over an exploration-stage asset, licence durability has two dimensions. One is the probability that the right survives. The other is how much value accumulated behind that right the legal architecture protects on the day it does not.

Aminex, a London-listed gas developer, holds a 25% non-operated interest in the Ruvuma production-sharing agreement in southern Tanzania. Its principal development is Ntorya, where ARA Petroleum Tanzania is operator and state-owned Tanzania Petroleum Development Corporation, TPDC, is building the pipeline connecting the field to the Madimba gas-processing system.

After a change of management and technical reappraisal at ARA Petroleum, the operator proposed changes to the approved 2026 programme. Aminex said the revised sequence would delay first gas and defer Chikumbi-1, an obligatory well under the Development Licence and Farmout Agreement.

Aminex and TPDC rejected that sequence. Aminex subsidiary Ndovu Resources issued a formal Notice of Dispute on 21 August, and a government-convened meeting five days later produced a revised programme.

Ntorya-2 testing is scheduled for November, first production for December and Ntorya-Central is expected to spud as NT-3 before year-end. Chikumbi-1 remains in the programme. The joint venture projects up to US$75 million of gross expenditure across the remainder of 2026 and 2027, while TPDC says about 95% of pipelaying and infilling on the Ntorya-Madimba line is complete.

Aminex had US$28.1 million of its development carry remaining at 30 June. Its simple 25% share of the entire US$75 million programme would be US$18.75 million, supporting management’s expectation that the carry can cover participating cash calls through commercial production, subject to which expenditure qualifies.

Another Tanzanian gas asset is approaching the opposite end of its tenure cycle.

Orca Energy Group’s subsidiary PanAfrican Energy Tanzania operates the mature Songo Songo gas field. Orca’s Q2 Interim Report states that the development licence granted to TPDC in 2001 remains set to expire on 10 October 2026.

The same filing said Orca’s request for commercially viable extension terms remained unresolved and described a high degree of uncertainty over operations after October. Non-essential capital projects had been put on hold.

Orca has separately agreed to sell its Tanzanian holding company to Taifa Gas Tanzania and Amber Energy Investment for a nominal US$10, alongside the transfer of obligations and liabilities.

Orca’s 13 April announcement defines the transaction document as the Share Purchase Agreement. A licence extension is not a stated condition to closing. But neither does the agreement lock the purchasers into taking that risk: Orca states that any party may terminate the Share Purchase Agreement for any reason.

The buyers therefore always retained an exit while the licence remained unresolved.

There is now a second source of uncertainty. On 20 August, Orca announced that the parties had extended the transaction longstop to 31 August 2026 because Tanzanian regulatory approvals remained outstanding. The notice also provided a post-longstop termination mechanism, in addition to the existing right of any party to terminate at any time for any reason.

The longstop passed 26 days before this edition. Orca’s public archive contains no later announcement through 26 September confirming that the transaction has closed, terminated or received another extension. Nor does it contain a subsequent announcement confirming an extension of the Songo Songo development licence.

Ntorya and Songo Songo show opposite ends of the same capital problem.

Ntorya has tenure and is trying to sequence development expenditure so discovered gas reaches revenue. Aminex’s carry removes much of its immediate financing burden, leaving execution as the principal risk.

Songo Songo has produced for more than two decades, but its existing legal term is running out while the transaction intended to transfer Orca’s Tanzanian business remains publicly unresolved.

The Share Purchase Agreement is revealing precisely because the headline sale does less risk-transfer work than it appears to. The at-will termination provision meant Taifa and Amber were never irrevocably committed to assume the tenure problem. The expired longstop adds another layer rather than creating the first one.

The nominal US$10 price should not be read as a valuation of Songo Songo’s gas. Orca says geological data belong to Tanzania, significant liabilities accompany the business and fixed operating assets become TPDC property when the licence and production-sharing agreement expire or terminate.

That makes 10 October concrete. Absent an extension or alternative arrangement, expiry changes not only the legal authority underpinning operations but the ownership of fixed operating assets.

Solway and Songo Songo therefore expose the same underwriting error at opposite ends of the asset cycle: the headline instrument can appear to carry more economic protection than its underlying legal terms actually provide.

Sinomine Resource Group, a Chinese critical-minerals producer, is expanding its Bikita lithium operation in Zimbabwe through subsidiary Sinomine Bikita Minerals.

The company has begun building a 600-tonne-per-year tantalum processing plant, targeted for completion in March 2027. Bikita is also expanding spodumene ore-processing capacity from about 2 million tonnes to 3.3 million tonnes annually.

A separate 100,000-tonne-per-year lithium sulphate project entered full-scale construction in August after receiving environmental approval and is scheduled for commissioning in mid-2027. Sinomine is also pursuing niobium and caesium recovery.

Zimbabwe’s beneficiation push is producing two economically different investments.

Lithium sulphate moves an existing product further down the processing chain. Tantalum, niobium and caesium recovery can potentially create additional saleable products from material already being mined or sitting in tailings.

Domestic processing and additional economic value are not synonymous.

A downstream plant can retain employment, tax base and industrial activity while also adding capital expenditure, energy consumption and operating cost.

Associated-mineral recovery has the cleaner commercial test. If Sinomine can turn minerals previously discarded, under-recovered or embedded in another stream into saleable products at competitive cost, Bikita produces more economic output from essentially the same orebody.

The next useful figures are therefore recovery, product specification, operating cost and return on the additional capital.
