Completion of MB01-N Maiden Drilling Programme

Oriole Resources PLC (AIM: ORR), the AIM quoted gold exploration company focused on Central and West Africa, is pleased to provide an update on the Mbe gold project in Cameroon ("Mbe" or the "Project"), where it has completed the maiden diamond drilling programme at the MB01-N target for some 3,000m (the "Programme"). Following this the Company's partner, BCM International Limited ("BCM"), has now earned a 50% beneficial interest in the Project.

Highlights

o The Programme has been completed for a total of 3,000.40m drilled in 15 holes.

o BCM has now earned a 50% beneficial interest in Mbe and the administrative work to formalise that interest, including the drafting of a joint venture agreement, is underway.

o Results for six holes are outstanding and are expected later in Q1-2026.

o On receiving these final results, the Company's consultant will prepare a maiden JORC Resource for the MB01-N target to add to the existing 870,000oz contained gold JORC Resource at the nearby MB01-S deposit.

o A fully funded step-out drilling programme is scheduled to commence at MB01-S in Q2-2026.

Chief Executive Officer of Oriole Resources, Martin Rosser, said: "We are delighted that the maiden drilling programme at the MB01-N target has been completed. The drilling crew and support personnel have worked tirelessly to achieve this on time and with excellent core recovery, and we thank them for their efforts. We look forward to reporting the remaining drill holes results and the consultant's maiden MRE report."

The Programme, which commenced in November 2025, was planned to test the MB01-N target, which is located 700m to the northeast of the MB01-S deposit, where the Company has previously reported a maiden JORC Inferred Mineral Resource Estimate of 24.8Mt at a grade of 1.09g/t Au for 870,000oz contained gold (see announcement dated 21 October 2025). MB01-N has a JORC Exploration Target of 15Mt to 20Mt at 0.77 to 0.94g/t Au for 370,000oz to 605,000oz contained gold, and offers significant upside to the total JORC Resource potential of the Mbe project. The Programme was designed to maximise conversion from an Exploration Target to a JORC Resource.

The Company today reports that the Programme has been completed for 3,000.40m drilled in 15 holes (MBDD025-039), of which 17.60m was abandoned and redrilled so the total being sampled is 2,982.80m. In accordance with the Completion Agreement (see announcement dated 5 November 2025), the Company can confirm that BCM has now earned a 50% beneficial interest in the Mbe gold project. The administrative work to formalise that interest, including the drafting of a joint venture agreement, is now underway.

Notable results from the first nine holes in the Programme (using a 0.20g/t Au lower cut-off grade) have included 21.70m at 3.13g/t Au including 7.20m at 8.19g/t Au (MBDD026), 16.10m at 2.49g/t Au and 14.80m at 0.73g/t Au (MBDD027), 16.20m at 0.77g/t Au including 10.10m at 1.08g/t Au (MBDD025), and 1.02g/t Au over 7.00m (MBDD031).

Results for a further six holes (MBDD034-39) are anticipated later in Q1-2026, after which the Company's consultant will prepare a maiden JORC Resource for the target to add to the existing 870,000oz contained JORC Resource at the nearby MB01-S deposit.

In addition, a fully funded step-out drilling programme is scheduled to commence at MB01-S in Q2-2026. Further details on this programme will be announced in due course.

Background on Mbe

After highly encouraging results from infill soil sampling, rock-chip sampling, and trench sampling, a fully funded maiden drilling programme commenced at the MB01-S target in late November 2024 and was completed in September 2025 for 6,828.40m in 24 holes. Best drilling results included 86.50m at 1.36g/t Au from 22.00m, including 39.40m at 2.00g/t Au (hole MBDD008), 21.30m at 1.61g/t Au from 2.40m (MBDD012) and 6.15m at 19.67g/t Au from 113.50m, including 1.00m at 119.10g/t Au (MBDD019). In October 2025, a maiden MRE was published for the MB01-S deposit of 870,000oz at 1.09g/t, using a US$3,200/oz gold price and a cut-off grade of 0.40g/t Au. Mineralisation at MB01-S remains open in all directions and at depth, and will be tested via a step-out drilling programme due to commence in Q2-2026.

At the MB01-N target, approximately 700m to the northeast of MB01-S, an Exploration Target range of 15Mt to 20Mt at 0.77g/t to 0.94g/t Au for 370,000oz to 605,000oz contained Au was published in July 2025, based on trenching data and the interpretation of geophysical and geochemical anomaly maps. The Exploration Target remains open in all directions and at depth, and it is anticipated that drilling of the target will result in a conversion to Resource ounces. An approximate 3,000m drilling programme has recently been completed which has seen BCM earn a 50% interest in Mbe. A maiden MRE for MB01-N is anticipated in Q2-2026.
