Fortuna Metals Validates Mkanda Rutile Project With 66kg HMC Result

Fortuna Metals Hits Key Processing Milestone as Maiden Resource Looms for Malawi Rutile Project

Fortuna Metals Limited (ASX: FUN) has delivered a significant technical milestone at its Mkanda rutile and graphite project in Malawi, producing 66 kilograms of rutile-bearing Heavy Mineral Concentrate (HMC) from a 5.4-tonne bulk sample — confirming a rutile grade of 1.22% and validating the project's processing potential. The Fortuna Metals Mkanda rutile project processing milestone in Malawi marks a pivotal step ahead of what could be a transformative resource announcement for the company.

The result, produced by specialist processing house Mineral Technologies in Johannesburg, marks the first time Fortuna has physically demonstrated the project's capacity to yield clean, separable rutile at grade. Combined with drilling programmes now running in parallel — and a maiden Inferred Mineral Resource Estimate (MRE) expected as early as late June 2026 — this announcement signals the company is accelerating from exploration discovery into a defined development story.

"The 66kg of rutile heavy mineral concentrate produced from our bulk sample is a key milestone for the Company to allow us to validate the ease of processing and high quality of our product before sending to downstream buyers for further independent test work… We look forward to a busy 2026 with major resource catalysts in the near future set to reposition Fortuna as not just a discovery story but a key global supplier of titanium, graphite and potentially monazite."

— Tom Langley, CEO, Fortuna Metals

What the Bulk Sample Result Actually Means

Metallurgical test work is often the bridge between an encouraging geochemical anomaly and a commercially viable project. The Mineral Technologies facility in Johannesburg subjected a 5.4-tonne bulk sample — drawn from three separate sites at Mkanda — to a rigorous, multi-stage processing workflow that closely mirrors commercial mineral sands processing.

The workflow included the following key stages:

• Feed preparation and drying
• Desliming using a Derrick screen (45 micron cut)
• Three-stage spiral plant concentration (rougher, scavenger, cleaner)
• Magnetic separation to isolate non-magnetic HMC
• Electrostatic separation (in final stages)

Pending analysis includes XRF, XRD, and QEMSCAN evaluation.

The 66kg of non-magnetic HMC produced at a 1.22% rutile grade is material because it does two things simultaneously: it confirms mineralisation converts efficiently into a clean concentrate under standard processing conditions, and it produces physical product samples to be sent to potential downstream buyers for independent qualification testing.

The next phase of test work targets the isolation of individual mineral streams — rutile, monazite, zircon, and ilmenite — with a specific focus on achieving a premium rutile specification of greater than 95% TiO₂. Final results from this analysis are expected by late June 2026.

Understanding Heavy Mineral Concentrate (HMC): A Key Concept for Investors

What is HMC?

Heavy Mineral Concentrate is the intermediate product produced when mineral sands ore is processed to remove lighter, low-value minerals (mostly silica sand), leaving behind the dense, economically valuable minerals. These "heavy minerals" typically include rutile, ilmenite, zircon, leucoxene, and monazite.

Why Does It Matter?

The production of HMC from a bulk sample is one of the earliest practical demonstrations that a deposit can actually be processed into saleable product. For investors, it answers a fundamental question: does this ore behave the way the geology suggests it should?

Drilling Programmes Advancing Rapidly Toward Resource Definition

Fortuna is running three simultaneous or near-simultaneous drilling programmes in 2026, each serving a different technical purpose and together forming the data foundation for what management describes as "expanded, high-confidence resource estimates."

2026 Drilling Programme Summary

The hand auger programme is being conducted on a nominal 200-metre spacing across high-priority rutile mineralised areas — a reconnaissance-scale grid designed to define strike continuity and identify the highest-grade zones for aircore follow-up.

The upcoming aircore programme is the programme most likely to generate significant newsflow. Aircore drilling provides deeper, more representative sampling than hand augers, typically capable of penetrating 40–60 metres or more, and allows the company to assess whether high-grade zones identified at surface extend with depth.

Furthermore, building on the 2025 baseline — which comprised 5,400 metres over 675 drill holes at an average depth of 8 metres — the 2026 programmes are specifically designed to transition the project from first-pass reconnaissance into resource-delineation mode.

Results from the 2026 programmes are expected to be reported regularly throughout 2026 and into H1 2027, with the maiden Inferred MRE anticipated in late June to early July 2026.

The Kasiya Comparison: A World-Class Deposit on the Doorstep

One of the most compelling aspects of the Mkanda project is its geological relationship to Sovereign Metals' (ASX: SVM) Kasiya deposit — the largest rutile deposit in the world and the second largest coarse flake graphite deposit globally.

Project Proximity and Geological Context

Both deposits sit within the same Lilongwe Plain weathered gneiss, a geological formation where tropical weathering over geological time has concentrated heavy minerals — including rutile — within the top 5–10 metres of the profile. This is an eluvial (residual placer) style deposit, where heavy minerals are concentrated in place rather than transported by water or wind as in traditional beach placer systems.

The hand auger results at Mkanda show a geometry remarkably similar to Kasiya — high-grade core zones flanked by lower-grade surface mineralisation, typically 2–4 metres thick. This structural consistency across Fortuna's ground is a meaningful indicator of geological continuity.

Kasiya's resource, for context, stands at 1,200 Mt at 1.0% TiO₂ and 1.5% TGC, with a rutile equivalent grade of 1.51% RutEq once graphite credits are included. It is the benchmark against which Fortuna's emerging resource will inevitably be measured.

CEO Tom Langley has also specifically flagged the potential for Mkanda rutile to meet high-end aerospace specifications, citing Sovereign Metals' results released in June 2025 that confirmed Kasiya rutile is a suitable feedstock for aerospace requirements — a premium end-market with demanding purity thresholds.

Multi-Commodity Optionality: Rutile, Graphite, and Rare Earths

While rutile is the primary focus, Fortuna is running graphite and rare earth analysis in parallel — a strategic decision that could materially enhance the project's overall economics.

Graphite: Coarse flake graphite is a known co-occurring mineral across the Lilongwe Plain. At Kasiya, graphite credits uplift the resource grade from 0.96% rutile to a 1.51% rutile equivalent — a meaningful economic enhancement. If Mkanda demonstrates similar graphite endowment, the same uplift potential applies.

Monazite: Fortuna is assessing monazite mineralisation as a priority, following Sovereign Metals' January 2026 announcement confirming strategic heavy rare earths at Kasiya. Monazite is a phosphate mineral that hosts rare earth elements — including heavy rare earths, which are in strong structural demand globally. The current bulk sample test work is specifically targeting monazite separation.

In-Country Laboratory: The company is establishing a low-cost facility in Malawi for initial heavy mineral separation steps, which management expects to reduce assay costs and accelerate turnaround times — directly supporting faster drilling decisions and resource development.

Near-Term Catalysts and Development Timeline

Fortuna's pipeline of near-term newsflow is unusually dense for a company at this stage of exploration, with multiple simultaneous workstreams converging over the coming weeks and months.

Key Milestones

The convergence of bulk sample processing results, aircore programme commencement, and the maiden MRE into a single narrow window in late June represents a significant volume of potential re-rating catalysts.

Why the Rutile Market Provides a Strong Commercial Backdrop

Natural rutile sits at the premium end of titanium feedstock quality. With a TiO₂ content of 93–97%, it is the preferred feedstock for the following industries:

• Titanium metal production — used in aerospace, defence, medical implants, and increasingly robotics
• TiO₂ pigment manufacture — the primary whitening agent used in paints, plastics, and coatings
• Welding electrodes — a large and growing industrial application

Titanium Market Snapshot

A structural supply tightening is underway as legacy natural rutile producers in traditional jurisdictions — notably Sierra Leone and Australia — continue to deplete existing deposits. New high-quality deposits of meaningful scale are rare, which consequently positions large-scale natural rutile discoveries in stable, accessible locations as strategically important.

Understanding Rutile: The Premium Titanium Feedstock

Rutile is a naturally occurring form of titanium dioxide (TiO₂) that represents the highest-grade source of titanium available in nature. Unlike synthetic rutile or lower-grade titanium minerals like ilmenite, natural rutile requires minimal processing to reach industrial specifications, making it the preferred feedstock for high-value applications.

The mineral's importance stems from titanium's unique properties: it is as strong as steel but 45% lighter, and it resists corrosion even in harsh environments. These characteristics have made titanium indispensable in aerospace manufacturing, where weight reduction directly translates to fuel efficiency and performance improvements.

In the emerging robotics sector, titanium's strength-to-weight ratio enables the construction of more agile, energy-efficient machines capable of precise movements whilst maintaining durability. As robotics applications expand from manufacturing into healthcare, defence, and consumer markets, demand for high-quality titanium feedstock is expected to grow substantially.

The Mkanda project's infrastructure setting strengthens its development case further. The project sits approximately:

• 20km from Lilongwe, Malawi's capital city
• 25km from rail access to the Nacala Corridor (11km at the northern boundary), connecting to the Nacala deep-water port in Mozambique
• 15km from high-capacity power lines
• Adjacent to plentiful fresh water resources

Why Investors Should Keep Fortuna Metals on Their Watchlist

The Fortuna Metals Mkanda rutile project processing milestone in Malawi represents far more than a single technical result — it reflects a company systematically de-risking its asset at pace. Fortuna controls 658km² of ground covering the majority of the same geological corridor that hosts one of the world's largest rutile deposits, at a stage where the resource definition process is about to deliver its first formal output.

The combination of factors building toward that maiden MRE — geological similarity to Kasiya, confirmed processing of HMC at grade, active drilling across multiple methodologies, and a multi-commodity opportunity in rutile, graphite, and potentially monazite — creates a convergence of catalysts that is rare at the early-stage exploration level.

The engagement of Mineral Technologies, one of the mineral sands industry's leading process engineering and testing firms, adds technical credibility to both the metallurgical programme and the concept-level engineering that is expected to follow. This includes preliminary capital and operating cost estimates to inform development pathways.

Fortuna Metals has positioned itself as an emerging player in the natural rutile space, controlling a large ground position in the same world-class geological setting as Sovereign Metals' Kasiya deposit. With a maiden Mineral Resource Estimate expected within weeks, bulk sample processing validating product quality, and aircore drilling about to commence, the company is approaching a pivotal inflection point that could fundamentally reframe its investment narrative — from explorer to defined resource developer.
