Central Rutile Project
Background on the Central Rutile Project
The Central Rutile Project consists of 5 exploration permits (Nganda, Bounde, Kombo, Alamba and Nsimbo) under valid applications covering 2,140km2 across an area rapidly emerging as a globally significant rutile province within Central Cameroon. The Project area is predominately underlain by a bedrock of kyanite-bearing mica schist which is thought to be the primary source of the rutile which is then concentrated and upgraded in the overlying saprolite material during the in-situ weathering process. This forms an in-situ, eluvial saprolite hosted rutile deposit target type analogous to Sovereign Metal’s Tier 1 Kasiya deposit in Malawi (the world’s largest primary rutile deposit at 1.8 billion tons at 1.0% rutile).
The exploration model then surmises that erosion, transporting and reworking by rivers then concentrate the rutile (and other valuable heavy minerals) into alluvial deposits. Historical production figures from the area between 1935 and 1955 have recorded some 15,000 tons of high purity (>95 %) rutile being produced from artisanal mining of the alluvial deposits around Nanga-Eboko. The Central Rutile Project borders Peak Mineral’s Minta Rutile Project where initial sampling has revealed widespread, high-value mineral assemblages with valuable heavy minerals (VHM) up to 93% of total heavy minerals (THM) and with the dominant VHM’s being rutile (up to 69.8%), monazite (up to 35.6%) and zircon (up to 21.5%) (see PUA Announcement “First systematic exploration programme discovers significant rutile province in Cameroon” dated 4 February 2025).
Background on the Central Rutile Project
On 11 June 2025, the Company announced results of an ongoing reconnaissance exploration program at the Central Rutile Project. Desktop studies incorporating detailed geological mapping, geophysics, and known mineral occurrences, were used to define initial, high priority targets for ground-truthing. The reconnaissance programme, which consisted of auger sampling, road-cutting channel sampling, soil sampling and stream sediment sampling, was successful in identifying heavy mineral (HM) and natural rutile mineralisation across all five tenements that make up the Central Rutile project. Rutile nuggets, ranging in size from 1mm+ to 2cm+, were observed in alluvial and eluvial (residual) sources. Samples collected from the initial exploration programme are currently being prepped for dispatch to the Company’s laboratory for analysis in South Africa, with results expected in August 2025.
To date, at the Central Rutile Project the Company has completed 3 auger drill holes (refer Figure 1), collecting 10 samples in the process, as well as collected 42 channel samples from 7 road cutting exposures, 1 surface grab sample and 2 stream sediment samples for analysis (refer Tables 1-4).

Note: reconnaissance auger holes ended in the ferruginous layer. The Company expects HM mineralisation to continue through the mottled and saprolite zones.

Cautionary Statement: The visual representation of heavy mineral (HM) and rutile mineralisation shown in this release is based on preliminary visual reconnaissance with no sampling results. Assay results are pending and have not yet been verified through laboratory analysis. Investors are cautioned that the information is indicative only and should not be relied upon as a definitive measure of mineralisation or economic potential. Further exploration and analytical testing are required to confirm the extent, grade, and economic viability of the mineralisation.
