Tusker Minerals Ltd (ASX: TSK) has discovered high-grade titanium mineralisation hosted predominantly as rutile within the company’s Mzimba Project in northern Malawi, Africa.
Over the last 12 months, I have learnt a lot about the titanium scene in which rutile is the King of the Castle. The focus is on rutile and not all HM deposits are found in the same way. Residual ruitle is the key and the establishment of titanium sources being sourced from rutile and not ilmenite is a step in the right direction.
Natural rutile is considered a premium titanium mineral because of its high TiO₂ (titanium dioxide ) content and relatively simple processing pathway compared to ilmenite.
About Tusker Minerals Limited
Tusker Minerals' exploration portfolio includes projects in Malawi and Cameroon, where geological environments resemble the Kasiya-style rutile systems currently attracting global attention. The company’s exploration approach relies on reconnaissance soil sampling, mineralogical analysis, and systematic follow-up drilling to identify zones of residual rutile enrichment.
The company's ASX announcement released on 12 March 2026 outlines early-stage reconnaissance sampling covering only a small portion of the company’s licence area.
Elevated titanium dioxide values.
Tusker Minerals' discovery comes from the company’s initial reconnaissance soil and rock-chip sampling program, which utilised XRF geochemical analysis and XRD mineralogical testing to evaluate titanium mineralisation across the project area (Figure 1).
Early results show significant near-surface titanium enrichment, with a large proportion of soil samples returning elevated titanium dioxide (TiO₂) values.

Importantly, the mineralogical analysis indicates that the titanium occurs predominantly as rutile, which is generally considered the most valuable natural titanium mineral due to its high TiO₂ grade and direct suitability for titanium pigment and metal markets.
The sampling program covered approximately 50 km², representing only around 7% of Tusker’s 710 km² licence package in the Mzimba region. The results provide an early validation of the project’s geological potential.
Tusker Minerals Highlights: High-Grade Rutile Titanium in Malawi
The key outcomes from the reconnaissance sampling program where Tusker Minerals discovered high-grade rutile titanium in Malawi include:
1. Strong Titanium Results from Surface Sampling
Soil and rock-chip sampling has identified elevated titanium oxide values across the Mzimba licences (Figure 2).
Key assay results include:
• Peak assay of 1.88% TiO₂• 47% of soil samples returned greater than 1% TiO₂• Titanium mineralisation identified across multiple sampling locations
These results demonstrate the presence of widespread near-surface titanium enrichment across the sampled areas.

2. Mineralogical Confirmation of Rutile
Tusker Minerals' Mineralogical testing using XRD analysis confirms that titanium mineralisation (Table 1) at Mzimba occurs primarily as:
• Rutile (dominant titanium mineral)
• Minor anatase
• No ilmenite detected
This mineralogical composition is important because rutile is typically considered the highest-value titanium feedstock due to its higher TiO₂ concentration.

3. Large Exploration Licence Package with Limited Initial Testing
The reconnaissance sampling program covered:
• Approximately 50 km² of ground; and
• Only about 7% of the total 710 km² licence area.
This means that a large portion of the project area remains untested, leaving scope for further exploration.
4. Geological Environment Comparable to Major Rutile Deposits
The geological setting at Mzimba is described as being comparable to other Malawian rutile systems, including the Kasiya deposit, which is currently recognised as one of the largest rutile discoveries globally.
The comparison is based on (Figure 3):
• Weathered saprolite profiles
• Residual titanium enrichment
• Geological source rocks capable of producing rutile through weathering
These characteristics suggest the potential for residual rutile mineralisation formed through deep tropical weathering processes.

Management Commentary
Chief Executive Officer Cliff Fitzhenry commented on the results from the reconnaissance sampling program.
He noted that the early sampling program 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 values reaching 1.88% TiO₂.
The mineralogical analysis confirming the presence of rutile is considered important because rutile represents the most valuable natural form of titanium dioxide mineralisation.
The company indicated that these results represent an early validation of the geological potential of the Mzimba Project, and that further systematic exploration programs are planned across the broader licence package.
Near-term Milestones to Watch
Following the reconnaissance results, Tusker Minerals has outlined several exploration activities that may advance the project:
• Expansion of soil sampling programs across the remaining licence areas
• Follow-up geochemical surveys targeting zones of elevated TiO₂ values
• Further mineralogical testing to confirm rutile distribution
• Systematic exploration programs designed to evaluate the broader 710 km² licence package
These programs are intended to determine whether the initial titanium enrichment identified during reconnaissance sampling extends across larger areas of the project.
Samso Concluding Comments
The reconnaissance sampling results reported by Tusker Minerals highlight the presence of widespread titanium enrichment across the Mzimba Project area. Nearly half of the soil samples returning greater than 1% TiO₂ indicates that elevated titanium concentrations occur across multiple sampling locations.
The mineralogical confirmation that the titanium occurs predominantly as rutile rather than ilmenite provides an important technical observation. Rutile typically contains a higher titanium dioxide content and is often considered a premium titanium feedstock in the global market.
Another aspect of the announcement is that the sampling program covered only a small portion of the overall licence area. The reconnaissance work was conducted across approximately 50 km² within a total licence package of around 710 km², leaving a large portion of the ground untested at this stage.
The geological comparison with other Malawian rutile systems suggests that the mineralisation may be associated with residual weathering processes similar to other rutile deposits in the region. Additional exploration programs will be required to determine the continuity and scale of the titanium mineralisation identified in this early sampling work.
Market Implication
As I have mentioned previously in one fo the other Samso News coverage, the market is now pretty much gold concentric. Anything else is not happening. With a market capitalisation of just under AUD $9M makes Tusker Minerals in the game for uplift with any good results. Looking at the share price journey of Tusker Resources Limited, the high of over AUD $0.35 is the potential, even thought the share price is at AUD $0.07 as we publish.

This is the name of the game and investors who have been in this sector for a while will attest to this form of thinking. The titanium narrative is quiet now but that does not make the business unattractive.
It is all about timing. Management looks good with Dan Smith as he has been in the deep end of the corporate world for a long time. He knows how to manoeuvre the ship and I am sure good news form the project will deliver capital gains for shareholders.
Cliff Fitzhenry as the CEO is based in South Africa and having a local is important to make things happen economically. At the moment, Tusker Minerals is looking at a project that has the potential for high-grade rutile, so DYOR and position for the market to return.
