Key Highlights

  • Maiden Inferred Mineral Resource of 298Mt @ 0.87% rutile and 1.19% TGC declared at Mkanda, with a high-grade subset of 159Mt @ 0.98% rutile and 1.11% TGC at a 0.8% cut-off
  • The Mkanda resource ranks among the top six globally by contained rutile tonnage (2.6 million tonnes of contained rutile), based on comparison with disclosed peer project MREs
  • Maiden aircore drilling at the Mlongo prospect delivers exceptional results including 24m @ 1.5% rutile from surface (MAC26_047), 25m @ 1.17% rutile (MAC26_019), and a best result of 3.43% rutile from 30–32m depth — the highest grade recorded at the project to date
  • Over 7,600m of deeper aircore drilling completed confirms significant resource growth potential beyond the current shallow ~8m average depth of the Inferred MRE

A Globally Significant Resource Takes Shape

Fortuna Metals Limited (ASX:FUN) has crossed a threshold that reframes how the Mkanda critical mineral project in Malawi should be viewed. The declaration of a maiden Inferred Mineral Resource of 298 million tonnes at 0.87% rutile and 1.19% total graphitic carbon positions Mkanda among the top six contained rutile deposits globally by disclosed peer project comparison — a ranking that takes the project from a compelling exploration story to a globally relevant critical mineral asset.

The total contained rutile in the resource is approximately 2.6 million tonnes, a figure that reflects both the scale of the mineralised system and the consistency of grade across the deposit footprint. The high-grade subset — 159Mt at 0.98% rutile at a 0.8% cut-off — provides a potentially higher-value development target within the broader resource envelope.

What Makes Mkanda Attractive

Several features of the Mkanda mineralisation are commercially relevant beyond the headline resource tonnage. The mineralisation is laterally extensive, hosted in soft, free-dig weathered material, and starts from surface — characteristics that suggest low strip ratios and reduced Mining complexity compared with hard-rock critical mineral deposits.

The current resource is based on an average depth of approximately eight metres, which is shallow by any measure. More than 7,600 metres of deeper aircore drilling has already been completed and demonstrates significant potential to extend the resource below the current ~8m average, with CEO Tom Langley indicating the 2.6 million tonne contained rutile estimate "looks set to only get bigger when we announce an updated Indicated resource mid next year."

That statement points to a resource growth pathway — converting Inferred to Indicated, and potentially expanding the resource boundaries — rather than a resource that is at or near its final extent.

Mlongo: A New Prospect Delivers

The maiden aircore drilling program at the Mlongo prospect, one of several prospects within the Mkanda project area not yet reflected in the current resource, adds another dimension to the growth story. The program delivered intercepts including 24m @ 1.5% rutile from surface (MAC26_047) and 25m @ 1.17% rutile (MAC26_019), with the highest grade recorded at the project — 3.43% rutile from 30–32m depth — also coming from Mlongo in hole MAC26_016 within a broader 7m @ 2.27% rutile zone.

These results confirm that Mlongo mineralisation lies below the base of the current shallow Inferred MRE, providing a clear rationale for further drilling to define a separate resource estimate for the prospect.

The Rutile and Graphite Market

Rutile is a high-titanium feedstock used in the production of titanium dioxide (pigment and metal) and welding electrodes. Supply is dominated by a small number of coastal mineral sands operations in Australia, Sierra Leone, and South Africa, and new large-scale deposit discoveries are relatively uncommon. A project hosting 2.6 million tonnes of contained rutile at surface-accessible grades sits within a market context of constrained supply and steady industrial demand.

The graphite component of the Mkanda resource — 1.19% TGC across 298 million tonnes — adds a secondary critical mineral dimension. Natural graphite is a key input in Lithium-Ion Battery anodes, and Demand projections linked to electric vehicle adoption have elevated graphite to critical mineral status in numerous government supply chain assessments.

Risks

The Mkanda resource is currently classified entirely as Inferred. Progressing to an Indicated resource requires infill drilling, metallurgical test work, and geological modelling that confirm the deposit's geological continuity at a higher confidence level. The rutile and graphite markets, while underpinned by industrial demand, are also subject to price cycles and can be affected by substitution (in the case of titanium feedstocks) or supply additions from competing projects.

The global ranking note carries an important caveat acknowledged by the company: peer project MREs also include higher-confidence Indicated and Measured categories, meaning direct comparison is imperfect.

What to Watch Next

The updated Indicated resource, flagged for mid-next year, will be the most significant near-term milestone for Mkanda. Progress on metallurgical test work, marketing, and offtake discussions — all identified as active workstreams — will also inform the market's view of the project's development trajectory. Any announcement relating to Mlongo resource delineation would represent incremental upside to the current 298Mt resource statement.

Sector Context

Critical mineral projects with globally significant resource scales have attracted strategic interest from governments and Downstream industrial buyers seeking supply chain security. Projects combining two critical minerals — rutile and graphite — in a single development with shallow, free-dig geometry are relatively rare, and Mkanda's positioning within that category gives it a profile that extends beyond the typical junior exploration narrative.
