Tusker Minerals (ASX: TSK) has identified high-grade titanium mineralisation dominated by rutile across its Mzimba exploration licences in northern Malawi following early-stage reconnaissance sampling.
Tusker reported a peak assay of 1.88% titanium dioxide (TiO₂) from soil and rock chip samples, with 27% of the 41 collected samples and 47% of the soil samples returning more than 1% TiO₂.
The results come from reconnaissance sampling across approximately 50 square kilometres, representing about 7% of the company’s 710 sq km licence package.
X-ray diffraction (XRD) mineralogical analysis confirmed that titanium mineralisation occurs predominantly as rutile with minor anatase present and no ilmenite detected.
High-Grade Rutile Systems
The Mzimba project area is underlain by rutile-bearing high-grade metamorphic rocks within the Irumide Belt, which hosts several residual rutile systems elsewhere in Malawi.
Tusker believes the geological setting is comparable to major Malawian rutile deposits including Sovereign Metals’ Kasiya project.
The fact that the reconnaissance program has only tested a small portion of the broader licence package leaves substantial exploration upside across the remaining tenure.
Tusker plans to advance systematic follow-up exploration programs including additional sampling and auger drilling across the broader licence area.
Further Exploration Planned
Chief executive officer Cliff Fitzhenry said the early results provided strong encouragement for further exploration at the project.
“Initial reconnaissance sampling has returned strong TiO₂ values across a relatively small portion of the licence area, [with] XRD mineralogical analysis confirming that the titanium is hosted predominantly in rutile and, to a lesser extent, anatase, with no ilmenite identified in the analysed samples,” he said.
Mzimba forms part of Tusker’s growing portfolio of rutile exploration assets in Africa alongside its Central Rutile Project in Cameroon as the company seeks to expand its titanium-focused exploration strategy.
In addition to the sampling and auger drilling, Tusker intends to review available geophysical datasets – including magnetic and radiometric surveys – to refine priority target areas.
“As global titanium demand accelerates in green technologies and high-performance industries, these assets strengthen our portfolio and offer substantial long-term value for shareholders,” Mr Fitzhenry added.
