Lion Rock Minerals Ltd (ASX: LRM) has reported drilling results from its Minta Project in central Cameroon, confirming widespread in-situ rutile mineralisation of up to 2.6% with multiple shallow intercepts, including 4m at 1.8% rutile.
According to management, the results define a continuous mineralised system across the Ayong Yerap Basin, with approximately 24 kilometres of strike, and zones remain open in multiple directions.
Ongoing infill drilling across both residual and alluvial targets is aimed at supporting a maiden Mineral Resource Estimate expected in the second half of 2026.
Lion Rock Minerals Limited – Large-Scale Rutile System Emerging in Cameroon
Lion Rock Minerals Limited has reported new assay results from its reconnaissance and infill drilling programs at the Minta Rutile and Monazite Project in central Cameroon.
The results confirm widespread in-situ rutile mineralisation across both residual and alluvial systems, with grades up to 2.6% rutile and multiple shallow intercepts.

The announcement highlights the definition of a significant alluvial basin at Ayong Yerap, extending over approximately 24km of strike and up to 500m in width, with mineralisation remaining open in multiple directions.
The ongoing drilling programs are designed to support the delivery of a maiden Mineral Resource Estimate (MRE), targeted for H2 2026.

About Lion Rock Minerals
Lion Rock Minerals Limited is progressing a large-scale rutile exploration story in central Cameroon, targeting both residual and alluvial heavy mineral systems.
The company is focusing on heavy mineral sands, particularly rutile, monazite, and zircon, within its flagship Minta Project in Cameroon.
The scale of the Minta Project, combined with consistent rutile intercepts and expanding drilling activity, positions the company within the critical minerals narrative, particularly in titanium feedstock supply.
The project covers approximately 8,800 square kilometres across 18 granted permits and additional applications in a historically underexplored but known rutile-producing region.
The mineralisation is interpreted to be derived from metamorphic processes acting on titanium-bearing minerals, with subsequent concentration into both residual plateau zones and large alluvial basins.
The company’s strategy is to define large-scale, near-surface heavy mineral systems with minimal overburden, allowing for potential low-cost development pathways.
Highlights – Broad, Shallow Rutile Mineralisation Across 24km Strike
The latest drilling results continue to demonstrate consistent shallow rutile mineralisation across the Minta Project:
Insitu rutile grades up to 2.6% reported
Key intercepts include:
4m @ 1.8% rutile (MRAU0306)
5m @ 1.3% rutile (MRAU0305)
6.5m @ 0.8% rutile (MRAU0169)
Mineralisation defined over a 24km strike length at Ayong Yerap Basin
Basin remains open to the north, south, and at depth
High-grade alluvial assemblages with up to 81% rutile in heavy minerals
Stage 2 infill drilling underway across 507km² target area
488 holes completed for 2,212m in early-stage infill drilling
Expansion to six drill rigs targeting additional high-priority zones
The results confirm the coexistence of both residual rutile systems and large alluvial basin targets, providing multiple exploration pathways.

Management Commentary
Lion Rock Minerals Ltd Chairman Robert Boston highlighted that the Ayong Yerap Basin results define a large-scale rutile system with significant exploration upside, particularly given its continuity over 24km and open-ended nature.
The technical team noted that the exploration strategy is confirming widespread rutile mineralisation across both residual and alluvial systems, with increasing confidence in defining a maiden resource.
The company emphasised that drilling is systematically advancing priority targets, supported by expanding operational capacity.
Near-trm Milestones to Watch
Completion of residual infill drilling to define grade continuity
Commencement of alluvial basin drilling, starting with Yong Basin
Expansion into Ayong Yerap Basin in Q3 2026
Delivery of mineralogical results from Minta Est granite
Progress toward maiden Mineral Resource Estimate (H2 2026)
Increased throughput from Yaoundé laboratory to accelerate results
Samso Concluding Comments
Lion Rock Minerals has a long session without any updates so this one should be a welcome relief for shareholders. The results presented confirm that the Minta Project hosts widespread rutile mineralisation across both residual and alluvial environments. The shallow nature of drilling and consistent intercepts indicate a large mineralised footprint.
The Ayong Yerap Basin is now defined over 24 kilometres and remains open. This provides a hope that there may be some form of indication that the project is not limited to isolated zones but may represent a continuous mineralised system.
It's good to see that the drilling strategy is expanding from reconnaissance into systematic infill work. The increase in drill rigs and target areas suggests that the company is moving toward defining scale rather than just confirming presence.
The next stage of work will be important in determining continuity and grade distribution. The delivery of a maiden resource estimate in H2 2026 will provide a clearer framework for understanding the overall size and potential of the project.
