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") permits in Cameroon, which comprises four licences: Ndom, Pokor, Niambaram, and Tenekou.  The Eastern CLP is contiguous with the Company's Mbe licence where the Company has recently reported a total Inferred Mineral Resource of 1.23Moz gold ("Au").

Highlights

·    Oriole has conducted a range of exploration programmes across its Ndom, Pokor and Niambaram licences within the Eastern CLP.

·    Recent selective rock-chip sampling at Ndom has returned gold grades of up to 17.00g/t Au, related to NW-trending quartz veins that show similarities with mineralisation observed at the Company's Mbe project.  Follow-up exploration is being planned.

·    Mapping and rock-chip sampling is currently underway at Pokor, on prior gold-in-soil anomalism identified in the south of the licence.

·    Soil sampling over earlier discovered stream-in-soil anomalism at Niambaram has been completed for 1,944 samples (including QAQC) and results are anticipated in H2-2026.  Results from selective rock-chip samples taken during the programme have returned up to 1.39g/t Au.

Chief Executive Officer of Oriole Resources, Martin Rosser, said: "The Eastern CLP licences, two of which adjoin the Mbe licence, which already hosts a major 1.23Moz deposit, have excellent district scale prospectivity for the discovery of gold.  We are especially pleased with the rock-chip sampling results at Ndom and eagerly look forward to follow-up work there and more results from ongoing exploration on the other Eastern CLP licences."

Further Details

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

In Q3 2021, the Company completed regional mapping and stream sediment sampling over the Eastern CLP and the Mbe licence area.  The results identified multiple areas of elevated gold in distinct drainage basins, associated with the northeast-trending Tcholliré-Banyo shear zone ("TBSZ") corridor and related structures.  Best results of 291 ppb Au and 95 ppb Au were returned from the Ndom and Tenekou licences respectively and a total of 18 areas graded >30 ppb Au.  Follow-up semi-regional soil sampling (400m by 200m spacing) over six initial grids confirmed anomalous gold in all four Eastern CLP, delineating multiple 2-3km long gold-in-soil anomalies across the Ndom, Pokor and Niambaram licences, as well as a broad zone of gold anomalism within the Mbe licence which the Company has prioritised to date.  However, the Company believes that the package presents a district-scale opportunity, with the potential to identify multiple further prospects similar to that identified at Mbe within the four Eastern CLP licences.

Following the renewal of all four licences for a further two-year term in June 2024, follow-up exploration has been completed across Ndom, Pokor, and Niambaram as detailed below.

Ndom

The results of the regional scale stream sampling programme identified gold-in-soil anomalism covering approximately 64km² of contiguous watersheds in the eastern part of Ndom.  However, the initial soil sampling over that area did not return significant gold anomalies compared to the results at Oriole's adjacent Mbe licence (Figure 2).  A reconnaissance visit of the area identified a thicker and more complex regolith cover than at Mbe, which may have masked the gold anomalism at surface, and thus this area required further investigation.

Alongside regolith mapping, 96 selective rock-chip samples (including QAQC) were collected across the area.  Rock-chip sampling typically targeted quartz veins and a tentative NW-SE trending control to the higher grading samples is interpreted, therefore similar to the controls on mineralisation observed at Mbe.  Best results include 17.00g/t Au, 0.93g/t Au, and 0.71g/t Au and were returned from a 3km x 2km zone, located to the north of a NE-SW trending granite ridge, which has coincident gold-in-stream sediment anomalism (Figures 1 and 3).

Follow-up work programmes at Ndom are currently being designed.

Pokor

Two soil sampling grids, PK01 and PK02, have been completed at Pokor for 2,490 samples including QAQC (see announcement dated 23 September 2025).  The Company subsequently acquired multi-elemental data on these samples using a pXRF and, based on the multi-element data and existing geological data, a prioritised batch of 1,154 samples (including QAQC) was selected for gold assay.

The results did not return any obvious gold targets for follow-up, with best results of 35ppb and 26ppb Au and so the team has re-focused its efforts on the anomalism already identified at the south of the licence, at PK01.  Mapping and rock-chip sampling is currently underway.

Niambaram

Two regional soil sampling grids (NM_Reg_01 and NM_Reg_02) were planned at 400 by 100m spacing targeting watersheds where anomalous gold-in-stream sediment results were identified in the northern half of the licence.  Preparation of the samples is ongoing and 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.

Follow-up work programmes at Niambaram will be designed upon receipt of the gold data from the soil sampling programme. 

Any meaningful results across the Eastern CLP will be announced as they are received.

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 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 underway 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 in progress.

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.
