Notes to Editors:

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

At its district scale Central Licence Package in Cameroon, the Company has identified multi-kilometre long gold anomalies, including at its flagship Mbe project.  At Mbe, the Company has recently published (23 July, 2026) a global JORC Inferred MRE of 1.66Moz contained gold at MB01, consisting of 1.3Moz at 1.01g/t Au for the MB01-S deposit, and 360koz at 1.05g/t Au for the MB01-N deposit.    Following the completion of the MB01-N drilling programme, and by meeting various financial commitments, BCM earned a 50% interest in the Mbe project, and Oriole has recently completed a corporate restructuring to confirm the Company's and BCM's respective 50% interest in Mbe.  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 in Cameroon, 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.  A JV agreement was signed in July 2026 and a work programme is due to commence in August 2026.

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