| SS012 | 2.07% | Continuous mineralisation |
CEO Tom Langley emphasised the significance of these results:
"The soil samples results have exceeded our expectations with large coherent kilometre scale prospects now defined across Mkanda which encouragingly covers more than 50km². This scale potential is significant when viewed in the lens of Sovereign Metals Kasiya discovery."
The Fortuna Metals rutile discovery in Malawi demonstrates exceptional continuity across multiple prospect areas. In addition, the results suggest substantial mineralisation potential that warrants immediate advancement to drilling phases.
Rapid Drilling Campaign Advancing on Multiple Fronts
Following the exceptional soil results, Fortuna has mobilised an expanded field team conducting systematic shallow hand auger drilling across the Mkanda project. However, the drilling program employs both 800m and 400m grid spacing to efficiently evaluate the large-scale rutile potential whilst focusing on high-priority zones.
Current Drilling Progress:
- 309 drillholes completed at Mkanda
- 28 drillholes completed at Kampini
- Average drilling depth: 8.5m (limited by perched water table)
- First assay results expected: Mid-December 2025
- Remaining results: Throughout Q1 2026
Consequently, the Company plans to transition to Aircore drilling from April/May 2026 to penetrate past the perched water table. This approach will reach the critical saprock boundary at approximately 20-30m depth. This represents the same geological horizon that proved instrumental in Kasiya's resource definition and economic viability.
Why Drilling Depth Matters for Resource Definition
The transition to deeper drilling methods is crucial for the Fortuna Metals rutile discovery in Malawi. For instance, the saprock boundary typically contains the highest concentrations of rutile mineralisation. Furthermore, reaching these depths will enable more accurate resource estimation and improved project economics.
Understanding Rutile: A Critical Industrial Mineral
Rutile is a naturally occurring form of titanium dioxide (TiO2) and represents the highest-grade titanium mineral. It contains approximately 95% TiO2 compared to 60% in ilmenite. This premium titanium feedstock is essential for producing titanium pigment used in paints, plastics, and paper, as well as titanium metal for aerospace and defence applications.
Key Properties of Rutile:
- Chemical composition: Nearly pure titanium dioxide (TiO2)
- Crystal structure: Tetragonal crystal system with high density
- Processing advantages: Requires less chemical treatment than lower-grade alternatives
- Industrial applications: Pigment production, welding rod coatings, titanium metal feedstock
Investment Significance of Rutile
Why Rutile Matters to Investors:
- Premium pricing over other titanium minerals due to high TiO2 content
- Growing demand from aerospace, automotive, and renewable energy sectors
- Limited global supply concentrated in few deposits worldwide
- Strategic mineral classification in many countries
The weathered gneiss deposits in Malawi offer advantages over traditional beach sand deposits. They enable easier processing and higher rutile concentrations in near-surface material. This geological setting creates conditions where tropical weathering concentrates heavy minerals in place, rather than requiring high-energy transport systems typical of conventional placer deposits.
Strategic Positioning Adjacent to World-Class Kasiya Deposit
Fortuna's projects are strategically located immediately south of Sovereign Metals' Kasiya deposit. Kasiya represents the world's largest rutile deposit and second-largest flake graphite deposit. This proximity provides significant geological validation for the Fortuna Metals rutile discovery in Malawi. Both projects target the same 70km strike extent of Lilongwe Plain weathered gneiss that hosts the rutile and graphite mineralisation at Kasiya.
Kasiya Benchmark Comparison:
- Kasiya resource: 1,200Mt @ 1.0% TiO2 within 49km² footprint
- Fortuna's anomalies: High-grade zones across 52km² and expanding
- Similar geology: Same weathered gneiss formation
- Analogous results: Comparable soil sampling grades and spatial extent
The enrichment process that created Kasiya's world-class deposit involved tropical weathering during the Tertiary period. This process concentrated heavy minerals in-place. Moreover, this geological process appears to have operated across Fortuna's project areas, suggesting similar resource potential exists within the same geological framework.
Geological Advantages of the Setting
The weathered gneiss formation provides several distinct advantages. For example, it creates naturally enriched zones of rutile mineralisation near surface. Additionally, the consistent geological conditions across the region suggest reproducible results between adjacent properties.
2026 Roadmap: Resource Definition and Expansion
Fortuna has outlined an aggressive exploration timeline targeting maiden resource definition in H2 2026. The strategic approach focuses on proving depth extensions to the saprock boundary. This was critical to Kasiya's resource expansion from initial discovery to world-class status.
Key 2026 Milestones:
- Q1 2026: Complete hand auger assay program
- April/May 2026: Commence Aircore drilling campaign
- Mid-2026: Target systematic drilling to 20-30m depths
- H2 2026: Maiden rutile resource estimate
The transition to Aircore drilling represents a crucial step for the Fortuna Metals rutile discovery in Malawi. Drilling to the saprock boundary was instrumental in Kasiya's resource growth. Furthermore, Fortuna's ability to reach these depths will be essential for demonstrating the full resource potential through deeper intersections of rutile-bearing material.
The Company plans to utilise 400m by 400m drill spacing to meet the required drill density for inferred resource estimation. This approach is consistent with the methodology employed by Sovereign Metals for their initial Kasiya resource definition.
