Asiamet KSK Copper Sale to Norin Moves to Completion

What happened

On September 7, Asiamet Resources confirmed that every condition precedent for the proposed sale of its wholly owned subsidiary Indokal Limited to Norin Mining (Hong Kong) Limited had been satisfied or waived. Indokal owns a 100% interest in the KSK Project. The parties are carrying out the remaining steps required for completion, which Asiamet expects shortly. The company will issue another announcement after completion.

The transaction was agreed in November 2025 for gross cash consideration of US$105 million on a cash free, debt free basis. Asiamet identifies Norin Mining as a Hong Kong incorporated subsidiary of Norinco Group. The sale would transfer the KSK Project and the associated BKM Copper Project to the buyer. Completion has not yet occurred, so legal control and payment remain pending.

KSK covers approximately 390 square kilometres in Central Kalimantan. Asiamet’s May 2025 study designed BKM as an open pit, heap leach and solvent extraction electrowinning operation capable of producing approximately 10,000 tonnes of LME Grade A copper cathode a year over an initial 12.8 year mine life. The study estimated total capital of US$178 million, including contingency, and a C1 cash cost of US$1.79 per pound. Those figures remain company study estimates rather than operating results.

Signal reading

The September update removes the outstanding conditions that had kept the transaction contingent. Its strategic significance lies in the approaching transfer of an advanced Indonesian copper portfolio from a junior company to a larger international operator connected to Norinco Group. Indonesia’s downstream copper policy gives the asset a national industrial context. Future value will depend on whether the new owner can finance and execute BKM after legal completion.

Next proof point: the formal completion announcement, transfer of Indokal ownership, receipt of the US$105 million consideration and a funded development plan from Norin Mining for BKM and the wider KSK portfolio.

Elevra Lithium published a Pre Feasibility Study for a three stage brownfield expansion of North American Lithium, its operating spodumene mine and concentrator in Quebec. Stage 1 is intended to lift plant throughput to the currently permitted rate of 4,500 tonnes a day from mid 2027. Stage 2 would expand milling capacity to 6,500 tonnes a day from mid 2028. Stage 3 would add a permanent crushing solution and further ore sorting capacity by mid 2029.

The study estimates average annual post expansion production of 373,000 tonnes of concentrate grading 5.4% lithium oxide, compared with 199,000 tonnes in the unexpanded case. Initial capital remains estimated at C$366 million, including C$73 million of contingency. The estimate is AACE Class 4 with a target accuracy range of plus or minus 40%. Elevra states that the expansion is fully funded through the strategic financing package announced in May 2026.

The expansion only case reports a post tax net present value at an 8% discount rate of C$943 million, a post tax internal rate of return of 49.9% and payback of 34 months. The production target is supported entirely by 47.2 million tonnes of Proven and Probable Ore Reserves at 1.12% lithium oxide. These values are study forecasts that remain exposed to commodity prices, exchange rates, grades, recoveries, capital delivery and operating performance.

Signal reading

North American Lithium is moving from scoping work into a reserve based, funded expansion study at an operating asset. The staged plan can bring additional production forward and distribute capital across several execution gates. The remaining uncertainty is operational: each stage must meet cost, throughput, recovery and schedule assumptions, while ore sorting must deliver the grade and productivity benefits incorporated into the study.

Next proof point: delivery of Stage 1 within the C$92 million allocation, sustained operation at 4,500 tonnes a day, evidence that ore sorting improves feed quality, and later execution of the 6,500 tonne daily milling and permanent crushing stages.

What happened

KEFI Gold and Copper reported that a serious security incident occurred at the Tulu Kapi Gold Project on September 4. The company said the incident resulted in multiple fatalities involving security personnel and community members, including one KEFI employee. It has not released further operational or security details because the situation remains sensitive and ongoing.

Project development began in March 2026 and had been directed toward first gold in mid 2028. Work before the incident included a new access road, progress on the electricity connection, plant and equipment orders and phased community resettlement. KEFI says the resettlement and compensation programme is being carried out under the applicable International Finance Corporation Performance Standards.

KEFI immediately suspended project development while it engages community representatives, Ethiopian Government authorities and security stakeholders. The company says activity will resume only after measures are established for a safe operating environment. Further project financing drawdown or deployment will be deferred during the assessment. KEFI reports sufficient capital reserves and committed standby facilities for the suspension period, while the effect on the development timetable remains unknown.

Signal reading

The incident has stopped physical work and delayed capital deployment at the same time. Tulu Kapi shows how personnel safety, community confidence and public security capacity sit inside project viability. The available disclosure does not support conclusions about the cause of the incident. The strategic issue is whether the company, communities and public authorities can establish conditions that protect people and support a durable return to development.

Next proof point: verified information on the response, agreed safety and community measures, a formal restart decision, the revised financing drawdown sequence and an updated construction and first production timetable.

What happened

Rox Resources reported substantial progress on the 1.0 million tonne annual Youanmi processing plant. Bulk earthworks are complete, the screen plant concrete is finished, the crusher foundation and fine ore bin tunnel have been poured, and the ball mill, ISAMill and carbon in leach areas are advancing. The first shipment of Albion tanks left in late August, while the primary, secondary and tertiary crushers are in transit.

Underground work completed 577 metres during August, including 431 metres of development across three mining areas and 146 metres of stripping in the historic Youanmi decline. Access to the first production levels at Youanmi Main has begun. Rox expects production stoping to start in October after final assays and grade control model updates.

The expanded camp is complete with 351 rooms. Its wastewater treatment facility has been commissioned and the new dining facility is operating. Rox says project funding and the final investment decision are in place and maintains its target of first gold in mid 2027. Conditions precedent for debt facility drawdown and one remaining major oxygen supply contract still require completion.

Signal reading

Youanmi is advancing the mine, processing plant, tailings facility, utilities and workforce accommodation as one operating system. The project has moved well beyond study and early procurement. Its execution quality will now be visible through the interfaces between underground development, ore stockpiling, equipment delivery, construction sequencing and commissioning readiness.

Next proof point: October production stoping, completion of the oxygen supply contract and debt conditions, delivery and installation of long lead equipment, plant commissioning, the planned ore stockpile and first gold in mid 2027.

What happened

Savannah Resources began the final preconstruction drilling programme at the Barroso Lithium Project. Two rigs are operating, one for geotechnical investigation and one for water monitoring bores. The programme is expected to take approximately four weeks. A third geotechnical rig and a fourth reverse circulation rig are expected to join during September.

The data will support final engineering for water reservoirs, the tailings storage facility, waste dumps, roads and bulk earthworks. Water monitoring will assess groundwater behaviour before, during and after construction and operation. Detailed reservoir engineering is also being prepared for the Execution Project report required within the remaining RECAPE licensing process.

Technical and environmental and social due diligence for project finance is well advanced, with reports intended for shortlisted potential lenders. Savannah has selected the process plant Front End Engineering Design vendor. The company also signed a memorandum with the parish church body in Boticas. That body will nominate a representative to the local consultative and monitoring committee that will review social performance and local development projects.

Signal reading

Barroso is moving from a completed Definitive Feasibility Study into the evidence required for detailed design, remaining licensing and lender review. Geotechnical conditions, groundwater behaviour, tailings design and social oversight can materially affect cost, schedule and finance. The project’s next stage depends on these workstreams converging in a design that is technically credible, institutionally authorised and capable of sustaining local scrutiny.

Next proof point: completion of the drilling and groundwater programme, final due diligence reports, commencement of FEED, submission and approval of remaining RECAPE documentation, binding project finance and a formal construction decision.

What happened

Rainbow Rare Earths and The Mosaic Company began a Pre Feasibility Study for the Uberaba project in Minas Gerais under their Joint Development Agreement. SRK Consulting has been appointed to prepare the first JORC compliant Mineral Resource Estimate. Mosaic is shipping approximately six tonnes of phosphogypsum feedstock to Rainbow’s laboratory and pilot plant in South Africa for further test work. The study is expected during the second half of 2027.

The study will examine an on site plant processing approximately 2.7 million tonnes of phosphogypsum residue a year over an initial 30 year project life. The previously modelled feed grade was approximately 5,100 parts per million total rare earth oxides. The proposed products are separated neodymium and praseodymium oxide and a mixed samarium, europium and gadolinium plus carbonate rich in medium and heavy rare earth elements, each at 99.5% purity.

Rainbow is adapting proprietary process knowledge developed for its Phalaborwa project to the Uberaba residue stream. A March 2026 Economic Assessment reported a post tax net present value of US$916 million, a post tax internal rate of return of 45% and average annual EBITDA of US$217 million using March spot rare earth prices. Those values are preliminary company estimates and are not results of the new Pre Feasibility Study.

Signal reading

Uberaba tests whether a flowsheet developed around one phosphogypsum resource can be transferred to another operating phosphate system. The opportunity begins with a large residue stream that already exists. Its strategic value will depend on mineral resource definition, repeatable pilot recoveries, reagent and residue management, product purity and evidence that the process can operate at the proposed throughput and cost.

Next proof point: the maiden Mineral Resource Estimate, representative pilot results, a defined mass and water balance, capital and operating estimates, product qualification and completion of the Pre Feasibility Study during the second half of 2027.
