Tusker Minerals (ASX: TSK) (Tusker) has intercepted high-grade titanium mineralisation hosted predominantly by rutile across its Mzimba exploration licences (Mzimba) in northern Malawi.
The Perth-based explorer said in an update on March 12 that the encouraging results came after a review of its initial reconnaissance soil and rock chip sampling programme, supported by XRF geochemical analysis and XRD mineralogical testing.
The results, Tusker said, represent an “important” early validation of the project’s prospectivity.
It said peak assay of 1.88% titanium oxide (TiO2) returned from soil and rock-chip samples, with 47% of soil samples returning more than one per cent TiO₂, which it said demonstrates strong near-surface titanium on the permit.
“We are very encouraged by these early-stage results from the Mzimba project,” commented Tusker’s CEO, Cliff Fitzhenry.
“Initial reconnaissance sampling has returned strong TiO₂ values across a relatively small portion of the licence area, with nearly half of the soil samples exceeding 1% TiO₂ and peak assays reaching 1.88%.
“Importantly, XRD mineralogical analysis confirms that the titanium is hosted predominantly in rutile and, to a lesser extent, anatase, with no ilmenite identified in the analysed samples.”
Tusker said the next phase of work at Mzimba will include additional wide-spaced and infill soil sampling to expand and refine the geochemical footprint; auger drilling to test the depth, distribution and continuity of rutile mineralisation, and review and interpretation of available geophysical datasets to refine priority target areas
Preliminary metallurgical testwork would be undertaken as well to assess rutile liberation and recovery characteristics, the firm said in the release.
