Reconnaissance Drilling at Dehane 2 Heavy Mineral Sands Project, Cameroon

BWA Group plc [AQSE: BWAP], which has mineral exploration licences in both Cameroon and Canada and is quoted on London’s AQSE Growth Market, provides an update on its Dehane 2 rutile sands Licence, located in Central Cameroon (“Dehane 2” or the “Dehane Project”).

The Dehane 2 licence covers an area of 54 km2. It includes 14 km of strike length of the Nyong river system, an area known to be prospective for Ilmenite, Rutile, Zircon and Kyanite heavy mineral sand mineralisation. Moreover, the licence covers some 20 km of the mouth of the Nyong River as it empties into the Gulf of Guinea. A river mouth can lead to a change in flow conditions that can cause the fluvial system to deposit any supplementary sediment including heavy mineral sand (“HMS”) it is carrying, where potentially economic accumulations of HMS are found within the lowest energy zone on the beach, the swash zone (Figure 1, 2 and 3). The swash zone was the target for the reconnaissance drilling.

Dehane 2 is located 166 km to the southwest of Yaoundé, and 70 km from the deep seaport and industrial zone of Kribi.

Work Completed

An initial first pass reconnaissance drilling programme was carried out between the 5th and 20th of November 2023, consisting of nineteen (19) shallow auger drillholes completed at a spacing of between 500 and 1000 metres along strike and around 50 to 100 metres across the project width where access permitted. Holes were drilled to an average depth of around six metres using the Archway track rig and approximately three metres using the Van Walt hand auger.  A total of 91 primary samples were collected and are currently undergoing analysis at Scientific Services CC, Cape Town, South Africa. Drillhole details are presented in Table 1.

Heavy mineral mineralisation was noticeable at the surface and within the down hole intervals and provides encouraging evidence for the potential economic accumulations of heavy mineral sands within this marine/estuarine environment. Within the drill core, medium and coarse-grained rutile, ilmenite and kyanite were observed in numerous continuous horizons, stacked upon each other. These horizons appear to be continuous layers of sand observed within the mouth of the Nyong River and in the south of the licence.  Where observed, rutile and ilmenite content varied between 15-20% in the southern areas and around 10-15% in the northern areas .
 

James Butterfield, interim Non-executive Chairman of BWA, commented:

“We are very pleased to have completed the preliminary reconnaissance drilling within the planned timeframe and budget at the Dehane 2 licence. BWA are even more encouraged by the presence of heavy mineral sands that have been observed within the medium and courser grained horizons within the drill core. BWA look forward to receiving the analysis and defining a more comprehensive and systematic drilling programme in the near future.”

Geology and Geological Interpretation

The Dehane licences are located in the Western Cameroon Domain, which extends along the border between Nigeria and Cameroon. This domain consists of a series of medium-grade to high-grade schists and gneisses of volcanic and volcano-sedimentary origin, intruded by later-stage granitoid complexes, the basement rocks are the source of heavy minerals.

The Nyong River is the main river which runs through the licence areas.  The BWAR licences allows access to approximately 60 km of the prospective Nyong River floodplain system, deltas, and associated tributaries.

The licences encompass a large active river system and an even larger paleo-floodplain area, and marine coastline observed in satellite imagery, although this has yet to be fully ground-truthed through fieldwork. This paleo-floodplain is likely to be a significant target for exploration and covers the length of the river with an initial expected width of over 2 km in the north and increasing in the south. Other rivers of various importance are found there: Owoumbé, Nkoudou, Bidinga, Mbebe, Mboke, and Ongué.

The Dehane area has been known for some historic small-scale artisanal historical rutile mining. However, the extent of its exploitation has not translated to concentrated modern exploration.

Mineralisation

Rutile and ilmenite were visible and identified in hand specimens in the field, during the drilling. Generally, the rutile grains are reddish and medium to coarse-grained compared to the black finer-grained ilmenite. Mineralisation observed is generally greater with thicker sands on the southern part of the Dehane 2 licence, compared to the Northern part where sand thickness generally reduces slightly. Rutile and ilmenite mineralisation was observed in all sand horizons with larger grains of heavy minerals located within the coarser sands.

Micas are generally observed from four metres downhole in some holes and five to six metres in others. This presence of micas may indicate a more proximal location to the gneiss bedrock. The average sand thickness in the field was approximately five metres, with thicker areas observed in the south and slightly thinner in the north, however, more drilling is required to confirm this trend.

The typical drillhole lithologies consist of a thin layer of organic soil-sandy material measuring less than 10 cm and containing less than 5% HMS, from the surface. This layer overlies a varying thickness of coarse to medium-grained sands, where the HMS is predominant. The gneiss bedrock's depth varies from around six to seven meters.
