Oriole Resources PLC (LON:ORR), the AIM quoted gold exploration and development company focused on Central and West Africa, has provided 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 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 9km2.

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.

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.

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.
