and Exploration Drilling and Analytical Results at Dehane 2 Heavy
Mineral Sands Project, Cameroon
BWA Group
plc [AQSE: BWAP], which has mineral exploration permits in
Cameroon, mining claims in
Canada, and is quoted on London’s
AQSE Growth Market, provides results from its recently completed
exploration drilling programme at its Dehane 2 rutile sands permit,
located in the South Region of Central
Cameroon (“Dehane
2” or the
“Dehane
Project”),
initially reported on 27 February
2024 (BWA
Group Plc - Reconnaissance Drilling at Dehane 2 Heavy Mineral Sands
Project, Cameroon).
The Dehane
Project is located 166 km southwest of Yaoundé, and 70 km from the
deep seaport and industrial zone of Kribi (Figure 1). The D2
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 Rutile, Ilmenite, Zircon and
Kyanite heavy mineral sand (HMS) mineralisation.
Moreover,
the licence covers some 20 km of the mouth of the Nyong River as it
empties into the Gulf of Guinea
and adjacent sandy beach-setting coastline. The beach swash zone
and the area extending inland by up to 150
m were the target for the 79-hole exploration drilling being
reported herein.
The
drilling programme was carried out between 9 September to
10 October 2024.
A total of
79 holes were drilled for 429.90 metres and 160 primary samples.
The programme targeted the areas south of the mouth of the Nyong
and where sampling completed by BWA in 2023 identified anomalous
HMS mineralisation (BWA
Group Plc - Reconnaissance Drilling Heavy Mineral Separation and
Analytical Results at Dehane 2).

Highlights
Seventy-nine
(79) holes were drilled for 429.90 metres and 160 primary samples.
The highlights of heavy mineral separation studies and X-ray
diffraction (XRD) analyses on the samples are presented
below:
-
HMS mineralisation
encountered from the surface down to the basement occurring at
depths around 6-10
m.
-
Total Heavy Mineral (THM)
raw sample grades up to 20.4% (16.4% VHM - kyanite,
rutile, ilmenite, garnet and zircon) over 2 metres
thickness.
-
THM and VHM significant
interval grades up to 8.3% and 6.3% over 6
metres.
-
THM significant
thicknesses up to 10 m at 3.3% (1.6%
VHM) and 7 m at 3.4% (2.1%
VHM).
-
Average slime of
3.9%.
-
Results outline a >1%
coherent VHM exploration near surface target area of approximately
12 km x 0.25 km aerial extent and average five metres of
thickness.
Jonathan Wearing, Chairman of BWA Group Plc,
commented:
“The
drilling results from the BWAR Dehane 2 licence are promising and
reinforce the BWA Board's confidence in the presence of heavy
mineral sands (HMS) mineralisation that may unlock future economic
potential. The percentages of total heavy minerals (THM) and
valuable heavy minerals (VHM) observed align with our expectations,
and the reduced levels of slimes are very
encouraging.
BWA is
excited to take this programme to the next level through geological
modelling and interpolation, paving the way for a maiden mineral
resource estimate (MRE).
It is
noteworthy to mention that the historic artisanal rutile mining
area of Akonolinga, extensively explored by other operators lies
upstream of the Dehane exploration permits on the Nyong river,
potentially demonstrating that the permits are analogous and
possibly connected to this historic rutile
district.
The
results demonstrate the existence of heavy mineral accumulations
with the composition, extent, and thickness that can lead to
significant future economic and commercial
opportunities.”
Work
Completed
The
results of a 19-hole first-pass reconnaissance drilling programme
(November 2023) were sufficiently
encouraging to complete a more detailed infill and exploratory
programme in September and October
2024. The programme consisted of 79 drillholes at a spacing
of between 250 and 500 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 percussive (hammer
driven) Archway track rig. Some 417 samples were
collected and composited within holes by similar lithologies to
give 160 composite samples, submitted to Scientific Services
Laboratory, Cape Town, South
Africa, for heavy liquid separation (HLS) and X-ray
diffraction (XRD).
Heavy minerals were
observed at the surface and within all drillholes. Within the drill
core, medium and coarse-grained rutile, ilmenite and kyanite were
observed in numerous horizons and appear to be continuous
throughout the layers of sand within the mouth of the Nyong River
and to the south.
Significant
downhole intercepts for THM% and VHM% were found. The intercepts
were calculated using a minimum thickness of 1 metre, a trigger
value of 0.5% THM, a minimum grade of 1% THM and a maximum of 1
metre of dilution.
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 (D1, D2
and D3) allow access to approximately 60 km of the prospective
Nyong River floodplain system, deltas, estuarine coastline 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.
Dehane 2
comprises approximately 14 kms 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.
Mineralisation
Rutile,
ilmenite and kyanite were visible during the drilling. Generally,
the rutile grains are reddish and medium to coarse-grained compared
to the black finer-grained ilmenite (reported on 27 February 2024).
The sands
are generally thicker towards the southern part of the Dehane 2
licence, although the XRD results show that the HMS mineralisation
is continuous and of similar grades (with some areas of higher and
lower grade, expected due to the nature of deposition. 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 in the drillhole near the boundary to
the gneiss bedrock.
The
typical drillhole lithologies consist of a thin layer of organic
soil-sandy material measuring less than 10 cm 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 between six to seven metres with depths down to ten metres
not uncommon.
