Eastern CLP Gold Exploration Update

 

Oriole Resources PLC (AIM: ORR), the AIM quoted gold exploration and
development company focused on Central and West Africa, is pleased to provide
an update on its 90% owned Eastern Central Licence Package ("Eastern CLP") in
Cameroon, which comprises four licences: Ndom, Pokor, Niambaram, and
Tenekou.  The Eastern CLP is contiguous with the Company's 50%-owned Mbe
licence ("Mbe"), where a JORC Inferred Mineral Resource of 1.23Moz gold ("Au")
has recently been reported.

 

Highlights

 

·    Further results from early-stage exploration across the licences
continue to support the Eastern CLP's district-scale potential.

·    Geological and regolith mapping over the PK01 target at Pokor,
identified by previously reported regional stream and soil sampling results,
has confirmed a comparable geological setting to Mbe.  Selective rock-chip
sampling of quartz veins within the mapping area has returned up to 1.24g/t Au
related to a 1km-long gold-in-soil anomaly.

·    At Ndom, mapping and rock-chip sampling was completed last month at
the ND02 target and returned up to 17g/t Au from selective quartz veins over a
3km x 2km zone (see announcement dated 16 April 2026).  An infill soil
sampling programme is currently underway over the ND01 target, located to the
southwest, using a combination of conventional soil sampling and auger
sampling methods.

·    Mapping and rock-chip sampling is also underway at Niambaram, to test
already identified rock-chip and soil sampling anomalism.

Chief Executive Officer of Oriole Resources, Martin Rosser, said: "Our recent
Eastern CLP exploration work and results continue to support the significant
prospectivity and potential we see for further gold discoveries to be made, in
addition to the major and current 1.23Moz JORC Resource reported at Mbe.  We
look forward to reporting further results from our work."

 

Further Details

 

The Eastern CLP, comprising the Ndom, Pokor, Niambaram and Tenekou licences,
is contiguous with the Mbe gold project, where a total JORC Inferred Resource
of 1.23Moz gold was reported last month (see announcement dated 13 April
2026).

 

A recent update on programmes across the Ndom, Pokor, and Niambaram licences
outlined a range of geological and regolith mapping, and rock chip sampling
results that started to demonstrate the district-scale potential of the
Eastern CLP for gold mineralisation (see announcement dated 16 April 2026).
The Company today provides an update on the work programmes still ongoing at
these licences.

 

Pokor

 

Following limited results at the northern target, PK02, the Company has
refocused on the gold-in-soil anomalism previously identified at PK01, in
southwestern Pokor, which had returned up to 120ppb Au.  Geological mapping
and rock chip sampling has now been completed over an area of approximately
9km(2).

soil sample data (200m x 50m) and Au contours.

 

The lithologies are comparable to those identified at Mbe, including a
basement orthogneiss unit that has been intruded by felsic dykes of granitic
composition and later mafic dykes.  The orthogneiss unit is locally observed
to be strongly silicified with visible sulphide minerals, and several
brecciated quartz veins that host sulphides are also observed in outcrop.

 

A total of 107 rock chip samples (not including QAQC) were collected during
the geological mapping and analysed for gold.  The rock chip results returned
14 samples >0.1g/t Au with best results of 1.24g/t Au and 1.01g/t Au.  The
higher grading samples are related to multiple NNE- to NE-trending soil
anomalies that cross-cut the broader 1km-long, N-S trending soil anomaly.

 

Ndom

 

In April 2026, results from selective rock-chip sampling over the ND02 target,
in the east of the licence, delivered best results of 17.00g/t Au, 0.93g/t Au,
and 0.71g/t Au from a 3km x 2km zone.  These grades were related to NW-SE
trending quartz veins that appear to be similar to those observed at Mbe, and
further work is being planned.

 

Meanwhile, follow-up infill sampling is underway at the ND01 target, located
to the southwest of ND02, identified by the semi-regional scale soil sampling
programme in 2021/22.  Recent regolith mapping highlighted that approximately
40% of the targeted area is underlain by an alluvial terrace ranging in
thicknesses from 0.5m to over 1.0m depth.  As such, the programme will be a
mix of soil sampling (over in-situ material) and auger sampling (over alluvial
terraces) to ensure representativity of the samples with respect to the
underlying geology by minimising the influence of any cover rocks.

previous regional soil sampling results, and underlain by a Digital Elevation
Model and generated streams

 

 

Niambaram

 

As previously reported, two regional soil sampling grids at Niambaram
(NM_Reg_01 and NM_Reg_02) were completed at a 400m by 100m spacing to target
watersheds in the northern half of the licence, over previously reported
anomalous gold-in-stream sediment results.  Results are anticipated in
H2-2026.

 

Alongside the soil sampling programme, 34 rock chip samples (including QAQC)
were collected over outcrops of interest, including quartz veins and strongly
silicified felsic rocks with disseminated sulphides.  Six samples graded
≥0.1g.t Au, with a best result of 1.39g/t Au, predominantly located at the
south edge of the soil grids.  Mapping and rock-chip sampling programmes are
currently underway to assess this area in more detail, as well as over two
further grids where results from the 2021/22 regional soil sampling had
identified anomalous gold-in-soil anomalism with individual sampling results
grading up to 57ppb Au.

data, regional scale stream data, and semi-regional soils data (Grid #4) at

and rock chip sampling.

 

The results reported today continue to demonstrate the wider prospectivity of
the Eastern CLP permits, which are contiguous with the 1.23Moz gold Mbe
project.

 

The work programmes are continuing across the Eastern CLP and any meaningful
results will be announced as they are received.

Notes to Editors:

 

Oriole Resources

 

Oriole Resources PLC is an AIM-quoted gold exploration and development
company, with projects in Central and West Africa.  It is currently focused
on projects in Cameroon.

 

At its district scale Central Licence Package, the Company has identified
multi-kilometre long gold anomalies, including at its flagship Mbe project.
 At Mbe, the Company has published a global JORC Inferred MRE of 1.23Moz
contained gold at MB01, consisting of 870koz at 1.09g/t Au for the MB01-S
deposit, and 360koz at 1.05g/t Au for the MB01-N deposit.  A fully funded
2,500m step out drilling programme is on-going at MB01-S with the aim of
further increasing the total resource at Mbe.  Following the completion of
the MB01-N drilling programme, and by meeting various financial commitments,
BCM has earned a 50% interest in the Mbe project.  Drafting of a JV
partnership agreement is nearing completion.

 

The Company has also reported a Resource of 460,000oz contained gold at
2.06g/t Au in the JORC Indicated and Inferred categories at its 50% owned
Bibemi project, where it has applied for an Exploitation Licence.
In November 2025, BCM completed its earn-in to give it a 50% interest in
Bibemi by meeting certain payment conditions, including spending US$4 million
on exploration.

 

At the Senala gold project in Senegal, AGEM Senegal Exploration Suarl
('AGEM'), a wholly owned subsidiary of Managem Group, has completed a
six-year earn-in to acquire an approximate 59% beneficial interest in the
Senala Exploration Licence by spending US$5.8 million.  The Company has
reported a Resource of 155,000oz contained gold at 1.26g/t Au (using a gold
price of US$1,800/oz)  in the JORC Inferred category for the Faré South
prospect, and an additional, complementary Exploration Target range of 17Mt to
24Mt at a grade of 0.69g/t to 0.84g/t Au for 380,000oz to 650,000oz contained
gold for all prospects at Senala.  Best results to date include 20.00m
grading 31.13 g/t Au including 10.00m grading 60.98 g/t Au from RC drilling
and 59.60m grading 2.20 g/t Au from diamond drilling.  Discussions on the
formation of a joint venture company are currently underway.

 

The Company also has several interests and royalties in companies operating
in East Africa and Turkey that could give future cash payments.
