THE SIGNAL
Guinea has formally inaugurated Nimba Gold Refinery in Conakry, three weeks after its first reported exports of domestically refined gold on 9 October. The government cites 733 tonnes of capacity, but reported design figures have varied and operating throughput remains undisclosed. Artisanal miners accounted for nearly 73% of Guinea's gold exports in the first half of 2026, making feedstock aggregation, traceability and commercial competitiveness central to refinery utilisation.
Rosatom says it has obtained authorisation for uranium test-well drilling at Leonardville in Namibia. Its chief executive also described broader permission to commence operations following an International Atomic Energy Agency (IAEA) visit. The precise authorisation remains unverified, particularly whether the water-use permit previously refused for pilot operations has now been granted.
Endeavour Mining has suspended underground operations at all three active portals of its Mana gold mine in Burkina Faso following an access ramp subsidence. No injuries were reported. The incident follows a fatal maintenance accident in March and a separate geotechnical pause at Aviera in July. Group guidance remains unchanged, although Mana's production impact is unresolved.
In Tanzania, Helium One has completed three shallow geological wells near its Itumbula discovery. They improve subsurface understanding but were not helium production tests. The Southern Rukwa farm-out remains in progress. Across these developments, regulatory permission, operating infrastructure and technical progress must be distinguished from sustained commercial output.

Guinea Formally Inaugurates Nimba Gold Refinery After First Refined Exports
Guinea's President Mamadi Doumbouya formally inaugurated Nimba Gold Refinery on 1 November 2026 at Gbessia, Conakry.
The facility was already operating. According to reporting citing the presidency's press office, its first domestically refined gold bars were exported on 9 October. The shipment's weight, value and destination were not disclosed.
The presidency cites capacity of 733 tonnes without publishing independently verified throughput.
Why it matters
The inauguration formalises a facility already participating in Guinea's new gold-export regime.
Decree D/2026/216/PRG/SGG, signed on 8 July, requires gold produced in Guinea to be refined domestically before export. It replaced the earlier Decree D/2026/212 of 3 July and, under Article 14, established a 90-day transition during which raw-gold exports could continue.
The transition expired in early October, before the first reported refined exports on 9 October. The domestic-refining mandate therefore appears operative, subject to subsequent exemptions or amendments.
A separate decree announced on 2 October established detailed export procedures. The Guinean Gold, Diamond and Other Precious Materials Assay Office (OGE) coordinates applications. Gold must be weighed, packed and sealed at the refinery in the presence of customs, central bank and anti-fraud representatives. Storage in refinery vaults is limited to 15 calendar days.
These procedures create a controlled custody and certification chain, but also introduce potential costs and logistical constraints for exporters.
Capacity claims require scrutiny. Africanews reported approximately 250 tonnes annually in June, while Reuters subsequently cited 530 tonnes annually initially, increasing to 733 tonnes at full capacity.
Guinea's 2025 mining statistics record 19,946 kilograms of industrial gold exports and 49,609 kilograms of artisanal exports, alongside approximately 2,565 kilograms from semi-industrial operations.
Artisanal gold represented approximately 69% of reported exports. That dependence increased in the first half of 2026, when artisanal mining accounted for 29.23 tonnes of the country's 40.28 tonnes of gold exports, nearly 73%.
This makes formalisation, aggregation and traceability of artisanal production central to refinery utilisation. Even the lowest reported annual capacity substantially exceeds Guinea's recorded domestic exports, suggesting regional feedstock may be necessary.
Some investment details are public. Bangaly Steve Touré, deputy head of Guinea's Mining Investment Fund, described a US$30 million facility. Reuters characterised the project as a public-private partnership, while Foreign Minister Morissanda Kouyaté described it as privately owned. The investors, ownership percentages and contractual arrangements remain undisclosed.
Article 11 of the 8 July decree provides that mining companies and licensed buying houses retain commercial ownership of their refined gold unless otherwise agreed in writing. Refineries act as processing-service providers for agreed fees, although they may also purchase gold through their commercial platforms.
Extractives Daily view
Guinea has progressed beyond commissioning announcements: domestic refining and exports have already begun.
The immediate question is how much gold Nimba has processed since early October, not when operations will commence.
Authorities should disclose throughput, verified capacity, ownership and tariffs. The effectiveness of mandatory refining will depend particularly on whether artisanal supply can be formalised and channelled through commercially competitive arrangements without undermining producer access to buyers.
Rosatom Claims Authorisation for Uranium Test Wells at Namibia's Leonardville Project
Russia's state-owned nuclear group Rosatom says it has received permission to begin drilling uranium test wells at Leonardville in Namibia's Omaheke region.
Interfax reported the statement on 30 October, attributing it to chief executive Alexei Likhachev. The Namibian reported the development on 2 November.
Likhachev also said an IAEA delegation had visited Namibia and that Rosatom subsequently received permission to commence operations. The precise authorisation and conditions have not been independently verified against a Namibian regulatory record.
Why it matters
The project, advanced through Rosatom subsidiary Headspring Investments Namibia, proposes in-situ uranium recovery above the Stampriet aquifer system.
The method circulates chemical solutions through mineral-bearing formations to dissolve uranium for extraction. It avoids conventional excavation but raises questions about groundwater protection, chemical containment, monitoring and restoration.
Leonardville has previously faced a specific regulatory obstacle.
In November 2021, Namibia's agriculture and water ministry withdrew two borehole-drilling permits after finding non-compliance with their conditions. New drilling authorisation therefore requires confirmation, while the separate in-situ recovery pilot remains under environmental review on the ministry's public portal.
Namibian authorities also sought IAEA technical assistance in assessing the proposed recovery method. The agency's findings may inform the government's assessment, but the IAEA does not issue Namibian mining or water permits.
Rosatom's announcement requires three distinctions: permission for exploration drilling, approval for an in-situ recovery pilot and authorisation for commercial uranium production.
Publication of the relevant permit would clarify its scope, issuing authority and environmental safeguards.
Extractives Daily view
Rosatom's statement may indicate progress in resolving Leonardville's regulatory obstacles, but it does not independently establish commercial mining approval.
Namibia's water authorities should confirm whether the previously refused permit has been granted and publish its conditions.
The wider test is whether Namibia can demonstrate a transparent, technically defensible licensing process for uranium recovery in a sensitive transboundary aquifer system.
Endeavour Suspends Mana Underground Operations After Access Ramp Subsidence
Endeavour Mining disclosed on 2 November that an access ramp at its Mana gold mine in Burkina Faso partially subsided on 28 October.
The ramp leads to the depleted Wona open pit and provides access towards the Dangouna and Aviera underground portals.
No injuries were reported. Underground personnel were evacuated, and mining at all three active underground portals was suspended pending geotechnical assessment.
Why it matters
The incident interrupts Mana's underground mining system, although lost production and remediation costs remain unquantified.
Endeavour says the Wona portal remains accessible and is assessing options to restart and accelerate mining there, alongside potential output from nearby open pits.
The latest disruption follows two earlier incidents at Mana during 2026.
On 9 March, Endeavour reported that a contractor had died on 6 March following injuries sustained during maintenance activities at the mine's scrapyard. The company stated that mining and processing continued without interruption while it investigated.
In July, Endeavour temporarily suspended mining in the Aviera area after identifying a surface fracture in the depleted Wona pit above the underground deposit.
The latest subsidence again restricts access to Aviera, reinforcing the importance of geotechnical stability for Mana's production and development programme. No causal connection between the three events has been established.
Endeavour maintains its 2026 group production and all-in sustaining cost guidance. That does not establish that Mana's individual performance will be unaffected.
Contractor exposure is also relevant. Perenti provides underground mining services through Underground Mining Services Burkina Faso, a joint venture with local partner Dynamic Mining Supply.
Endeavour has not disclosed a restart date, quantified production impact or remediation cost. It intends to provide further details alongside third-quarter results on 12 November.
Extractives Daily view
Mana's operational and geotechnical history makes mine-level performance more informative than maintained group guidance alone.
The 12 November update should establish the remediation timetable, alternative mining capacity, production consequences and implications for underground contractors.
Restart decisions must remain conditional on demonstrated ground stability rather than production-recovery targets.
Helium One Completes Three Shallow Geological Wells at Tanzania's Itumbula Discovery
Helium One Global reported on 2 November that it had completed three shallow stratigraphic wells near its Itumbula helium discovery in southern Tanzania.
Each well was drilled to less than 100 metres within the company's 480 km² Southern Rukwa mining-licence area.
The wells were designed to improve shallow basement geological interpretation and seismic control. They were not helium production or flow-test wells.
Why it matters
The drilling improves information for planning deeper development wells, but does not establish additional recoverable resources or commercial helium flow.
Helium One continues evaluating its earlier extended electric submersible pump testing programme and planning an initial cluster of basement development wells.
The Southern Rukwa farm-out remains underway with adviser PVE Consulting. No completed transaction or binding financing terms have been announced.
A farm-out could introduce a partner and development capital in exchange for a project interest. Its significance will depend on ownership dilution, expenditure obligations and conditions precedent.
The filing also reports progress at Helium One's separate 50%-owned Galactica-Pegasus project in Colorado, operated by Blue Star Helium.
Blue Star reported A$460,000 in quarterly helium-sales receipts on a 100% joint-venture basis. Its operator share was approximately A$190,000 after royalties and before production taxes. Helium One's share is to be forwarded under the operating agreement.
Those receipts should not be attributed entirely to Helium One or presented as Tanzanian revenue.
The Colorado venture also expects to begin drilling three additional production wells in March 2027 following permitting delays.
Extractives Daily view
The Itumbula wells are geological preparation, not evidence of imminent commercial production.
The next meaningful Tanzanian milestones are deeper drilling, independently supportable flow evidence and a completed farm-out with disclosed capital commitments.
Colorado production and sales remain separate from Southern Rukwa's development and financing position.
WHAT TO WATCH NEXT
Guinea: Nimba Gold Refinery's verified throughput, artisanal feedstock arrangements, ownership and partnership terms, refining tariffs, export processing and compliance with the domestic-refining decree.
Namibia: Confirmation of Leonardville's water-use permit, authorised drilling scope, IAEA findings, pilot conditions and groundwater safeguards.
Burkina Faso: Endeavour's 12 November Mana update, geotechnical remediation, underground restart, mine-level production consequences and Perenti's exposure.
Tanzania: Southern Rukwa's deep-well timetable, farm-out completion, capital commitments and helium-flow evidence; separately, Colorado production and permitting progress.
