Fortuna Metals (ASX:FUN) lands top-6 global rutile resource at 298Mt and 0.87%

Hand auger drilling delivered the maiden number. Aircore holes averaging 27m are already testing what sits underneath.

Fortuna Metals (ASX:FUN) has delivered its maiden Inferred Mineral Resource Estimate at Mkanda in Malawi, and the headline number is 298Mt at 0.87% rutile and 1.19% total graphitic carbon at a 0.7% cut-off. That puts Mkanda inside the top six contained rutile deposits globally on the company’s peer table.

The higher-grade slice matters just as much. At a 0.8% cut-off the resource still holds 159Mt at 0.98% rutile, meaning a meaningful chunk of the tonnage carries grade well above what most peer projects can show.

We flagged in earlier coverage that the maiden number would be built almost entirely on shallow hand auger holes averaging 8.4m depth. That is exactly what has landed.

The interesting part is what the announcement quietly telegraphs about the next update. Fortuna has already sunk 14 aircore holes averaging 27m depth, and those results are not in this MRE.

Why the top-6 ranking earns a careful read

Ranking tables in maiden announcements deserve scrutiny. Fortuna is upfront that most of its peers on the top-6 list carry Indicated and Measured tonnes, while Mkanda is entirely Inferred. That is a real caveat and the company puts it in bold.

The skeptical read is that Inferred tonnes at 400m by 400m spacing sit at the softer end of the confidence scale. The constructive read is that Fortuna has still cleared the tonnage bar that took its peers years and multiple drill campaigns to reach.

The 96.6% TiO2 rutile product from the July bulk sample also stays relevant. The tonnage corresponds to a product that already looks commercially credible against Kasiya, Sierra Rutile and Kwale.

The 27m aircore holes are the real signal for the next MRE

Our previous piece on Fortuna focused on why the aircore program mattered. That thesis just got a data point. The first 14 aircore holes average 27m, more than three times the hand auger depth behind this maiden resource.

The comparison the market will draw is Sovereign Metals’ Kasiya, 20km north, where the move from hand auger to aircore lifted the resource from around 644Mt to roughly 1,800Mt. We are not saying Mkanda repeats that arithmetic. We are saying the geological setting supports the same style of depth extension test.

Assays from the aircore program are expected in H2 2026. That update determines whether today’s 298Mt is a floor or a ceiling.

Graphite, zircon and monazite quietly widen the story

The maiden MRE also carries 3.55Mt of contained graphite at 1.19% TGC. At Kasiya, graphite credits lift the rutile equivalent grade from 0.96% to 1.51%, so a comparable uplift at Mkanda would change how the economics get modelled.

Zircon and monazite are still being characterised through H2 2026. If either delivers, the project shifts from rutile-graphite to a multi-commodity critical minerals story, with strategic heavy rare earths sitting in the monazite fraction the way they do at Kasiya.

The risk is straightforward. None of these by-product credits are locked in until metallurgical work confirms recoveries and product quality.

The Investors Takeaway for Fortuna Metals

The maiden MRE clears the tonnage hurdle and sets the base case. The harder question is whether the aircore results in H2 2026 deliver the depth extension that turns 298Mt into something materially larger, and whether infill drilling can move the resource toward Indicated in time to underpin scoping and feasibility studies through 2027.

The WNDRCO US strategic partner vesting condition still sits in the background until 2029, and it remains the piece of the story that could reshape ownership economics later. Investors can read our prior coverage of the aircore program and the 96.6% TiO2 product spec at stocksdownunder.

Fortuna has walked into the top six global rutile deposits with its first published number. The next MRE update determines whether that ranking hardens or gets rebuilt entirely.
