Machinga exploration commences as ex-China Dy and Tb prices surge
AuKing Mining has started exploration targeting at its 100%-owned Machinga Heavy Rare Earths Project in southern Malawi. The project carries a demonstrated enrichment in dysprosium and terbium, the two magnet rare earths now in shortest supply outside China.
Targeting underway across a largely untested system
AuKing has completed the compilation, validation and interpretation of historical drilling, geochemical and geophysical data at Machinga. The integrated review has generated multiple priority Areas of Interest (AOIs) linked to regional uranium radiometric anomalies, interpreted structural corridors and prospective geology.
These AOIs sit largely outside the footprint of historical drilling and surface sampling. They provide AuKing with two clear exploration objectives:
- Extensions to known REE-Nb mineralisation along strike and at depth.
- New zones across the broader 200.4 km² licence area.
- Geological control: initial core and field reviews link alkaline granitic and pegmatitic rocks to interpreted structures and elevated uranium responses.
- Funded program: field work starts this month, with a UAV magnetic and LiDAR survey targeted for early December 2026.
The announcement follows AuKing's completion of the Green Exploration Limited acquisition from Tusker Minerals in October 2026, which secured 100% of Machinga close to the company's Zomba operations base.
Why the Dy+Tb ratio matters
Most rare earth deposits are dominated by light rare earths. Dysprosium and terbium make up a small fraction of the basket but drive a disproportionate share of value, because they allow NdFeB magnets to operate at high temperatures in defence systems, EV drivetrains and wind turbines.
Dy+Tb as a share of TREO
Machinga average from historical mineralised samples above 0.25% TREO; best interval is MDD008 (3m from 45m). Peer figures are from company and industry disclosures and are not directly comparable resource-to-exploration data.
Same system as Bokan Mountain
Machinga is hosted in a peralkaline igneous system of the same style as Bokan Mountain in south-east Alaska, one of North America's most significant heavy rare earth deposits. Bokan, owned by Ucore Rare Metals, carries close to 40% of its TREO as heavy rare earths and has attracted a US$145m bond authorisation from the Alaska Industrial Development and Export Authority.
Nb credit
Every reported interval carries niobium, up to 1.01% Nb2O5, a further critical mineral by-product.
Near surface
MR024 and MR019 are mineralised from surface. MDD006 starts at 3m.
Consistent ratio
Dy+Tb/TREO sits between 3.6% and 4.1% across every reported interval.
Chilwa Province
Same alkaline province as Mkango's Songwe Hill and AuKing's Tundulu project.

HREO % expressed as HREO/TREO x 100. Grade x width = TREO % multiplied by interval length (m). Machinga does not currently host a JORC-compliant Mineral Resource.
Western prices decouple as Chinese exports stop
S&P Global reported on 30 September 2026 that North American dysprosium and terbium oxide prices had reached new highs on US stockpiling and tight Chinese exports. Buyers are competing for constrained non-Chinese supply ahead of stricter defence-sector sourcing rules.
China's April 2025 export controls on dysprosium, terbium and yttrium, and their subsequent tightening, have pushed Western end users towards geographically diversified heavy rare earth sources. Projects with a demonstrated Dy+Tb weighting are the direct beneficiaries of that shift.
What this means for Machinga
- Heavy rare earth enrichment now commands strategic, not just commercial, interest.
- Malawi has emerging rare earth infrastructure, with Lindian's Kangankunde targeting first production in Q4 2026.
- AuKing enters drill target definition at a point of peak market attention on ex-China HREE supply.
Valuation context: Malawi and HREE peers
AuKing's market value sits well below rare earth peers in Malawi and the heavy rare earth sector. Peers are at more advanced stages, with defined resources, studies or construction, which accounts for much of the gap. The comparison shows the value the market assigns as projects progress.

| Company | Project | Stage | Market value |

| Sovereign (SVM) | Kasiya, Malawi 2.5% Dy+Tb/TREO in monazite | DFS | ~A$403m May 2026 |
| ASM (acquired) | Dubbo, NSW Polymetallic REE incl. Dy/Tb | Takeover | US$299m Jan 2026 |
| Mkango (MKA) | Songwe Hill, Malawi Carbonatite REE, Chilwa Province | DFS | ~C$298m Jul 2026 |
Key observations
- District re-rating: Lindian and Mkango have established southern Malawi as a recognised rare earth jurisdiction, with Lindian approaching first production.
- HREE premium: Ucore trades on heavy rare earth exposure, with Bokan Mountain valued for its Dy and Tb content rather than tonnage.
- Geological analogue: Machinga shares Bokan Mountain's peralkaline host, and its 29% HREO/TREO ratio points to a heavy-weighted basket.
- Low entry cost: AuKing acquired Green Exploration, including Machinga, for consideration of up to A$4.85m.
- Value pathway: peers gained recognition through drill-out, maiden resources and studies. Machinga is at the start of that sequence.
