Updated JORC Resource for Bibemi Gold Project in Cameroon -

23% increase to 375,000 oz grading 2.30 g/t gold Inferred

Oriole Resources PLC, the AIM-quoted gold exploration company focussed on West Africa, is pleased to report an updated Inferred JORC-compliant Mineral Resource Estimate ('MRE' or the 'Resource') of 375,000 Troy ounces ('oz') grading 2.30 grammes per tonne ('g/t') gold ('Au') for Bakassi Zone 1, one of four prospects at its 82.2%-owned Bibemi orogenic gold project ('Bibemi' or the 'Project') in Cameroon.

Highlights

·    An updated MRE has been prepared by independent consultant Forge International Limited ('Forge'), predominantly on the basis of an updated gold price, as part of the ongoing technical studies to support the application for an exploitation licence later this year;

·    The pit-constrained Resource is estimated to be 5.1 million tonnes grading 2.30 g/t Au for approximately 375,000 oz Au in the JORC Inferred Resources category, reflecting a 23% increase in the resource inventory;

·    The entire Resource has been defined within the limit of a US$2,000/oz gold price pit shell;

·    The Resource has been modelled over a strike length of approximately 1.3 kilometres ('km') and to a depth of 263 metres ('m') below surface, using a cut-off grade of 0.45 g/t Au and a top-cut of 20 g/t Au;

·    The updated MRE is open at depth and along strike to the northeast;

·    There exists significant potential to expand the MRE at Bakassi Zone 1 and to identify additional resources at the other three prospects on the licence, namely Bakassi Zone 2, Lawa West and Lawa East, which are all located within a few kilometres of Bakassi Zone 1;

·    Processing of the geophysics data collected in 2023 is currently underway to aid drill targeting at Bibemi (including at the other three prospects) as well as future Resource-expansion activities.

Oriole CEO, Tim Livesey, said: "We have been pleased to see the maiden resource support this pit expansion and deliver not only additional tonnes, but also at a higher grade.

"As we progress toward our fifth phase of drilling at Bibemi, with our partners BCM, we look forward to further expansion of the Bakassi Zone 1 Resource. We are also keen to test and define the potential at the other three prospect areas. 

"This project is shaping up to be very robust and offers the opportunity for early development of a potential multi-pit gold mining operation."

Further Details

At the Bibemi orogenic gold project in northern Cameroon (177km² in area), the Company's exploration to date has identified shear-hosted gold mineralisation at four main prospects - Bakassi Zone 1, Bakassi Zone 2, Lawa West and Lawa East - within a circa 12 km-long mineralised hydrothermal system at surface. Since Q1-2021, the Company has completed four phases of diamond drilling at the Project for a total of 6,685.40m in 54 holes.

The majority of the drilling has been focussed on a circa 1 km section at the southern end of Bakassi Zone 1 and has delivered best intersections of 14.80m grading 4.27 g/t Au and 7.70m grading 2.74 g/t Au (hole BBDD050), 6.50m grading 3.92 g/t Au (hole BBDD034), 5.20m grading 1.97 g/t Au (hole BBDD031), and 9.20m grading 1.31 g/t Au (hole BBDD042) (announcements dated 20 December 2021, 9 February 2022 and 15 September 2022). The shear corridor at Bakassi Zone 1 has been confirmed up to 150m wide and contains a package of steeply-dipping quartz-tourmaline veins as well as extensional, sub-horizontal quartz veins. Both vein sets appear to be mineralised.

In December 2022, the Company reported a maiden JORC Mineral Resource Estimate for Bakassi Zone 1 of 4.3 million tonnes grading 2.19 g/t Au for approximately 305,000 oz Au in the JORC Inferred Resources category. This estimate was defined within a US$1,800/oz gold price pit shell.

The Company today reports that independent consultant Forge, together with its associate Axe Valley Mining Consultants Ltd, has produced an updated MRE for Bakassi Zone1, as part of ongoing technical studies to support the application for an exploitation licence later this year. The MRE for Bakassi Zone 1 now stands at 5.1 million tonnes grading 2.30 g/t Au for approximately 375,000 oz Au in the JORC Inferred Resources category, based on a 0.45 g/t Au cut off and within a US$2,000/oz gold price pit shell (Table 1).

The approximate 23% increase in the resource inventory largely reflects the robust improvement in the mid- to long-term gold price forecasts.

Notes:

·      Effective date of the Mineral Resource is 15^th December 2023.

·      The Operator of the Bibemi Project is Oriole Resources PLC.

·      The Resource Estimate is shown on a gross (100%) basis of the Bakassi Zone 1 target within the Bibemi Project. Oriole currently holds an 82.2% net attributable beneficial interest through the licence holding company, Reservoir Minerals Cameroon SARL. The remaining 17.8% interest is held by two of the Company's partners: 10% by BCM International Limited, and 7.8% by Bureau d'Etudes et d'Investigations Géologico-minières, Géotechniques et Géophysiques SARL ('BEIG3').

·      All figures are rounded to reflect the relative accuracy of the estimate. Differences may occur due to rounding.

·      Mineral Resources are not Mineral Reserves and have not demonstrated economic viability. It is uncertain if further exploration will convert Inferred Mineral Resources to higher confidence categories.

·      To define the blocks with reasonable prospects of economic extraction, the Inferred Mineral Resource Estimate is reported above a cut-off grade of 0.45 g/t and constrained within wireframe models representing the mineralised bodies and within a Lerchs-Grossman optimised pit shell based on a gold price of US$2,000 / oz, with the application of reasonable mining parameters.

·      The Resource has been estimated by Mr. Robert Davies, EurGeol, CGeol, a Competent Person as defined in the 2012 Edition of the 'Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves' (The JORC code).

As per the previous maiden Inferred Mineral Resource Estimate, the updated MRE has been estimated using the same 28 diamond holes for a total of 3,840m. No new drilling has been completed since the December 2022 MRE. However, the improved gold price has increased the size of the Resource pit shell, resulting in an increase in the strike length of the resource model to 1,268m (from 1,220m), and a slight extension of its depth to 263m below surface. The Resource, which has been estimated using a cut-off grade of 0.45 g/t Au and a top-cut of 20 g/t Au, is not sensitive to cut-off grade, as can be seen in the grade tonnage sensitivity shown in Table 2.

Estimation of a new Exploration Target for the Project is pending review of ground-based geophysics (magnetic) data, collected during 2023, which is currently being processed by independent consultant Terra Resources Pty Ltd to assist will drill targeting at all four prospects.

Notes to Editors:

Oriole Resources PLC is an AIM-listed gold exploration company, operating in West Africa. It is focussed on early-stage exploration in Cameroon, where the Company has reported a Resource of 375,000 oz Au at 2.30 g/t in the JORC Inferred category at the Bibemi project and has identified multi-kilometre gold and lithium anomalism within the district-scale Central Licence Package project. At Bibemi, BCM International has made a signature payment of US$500,000 to the Company and is currently earning up to a 50% interest in the project by funding up to US$4m in exploration expenditure and JORC resource-based success payments. A similar deal at Mbe (part of the Central Licence Package) is expected to be completed before the end of the current month.

At the more advanced Senala gold project in Senegal, AGEM Senegal Exploration Suarl ('AGEM'), a wholly-owned subsidiary of Managem Group, has earned an initial 51% beneficial interest in the Senala Exploration Licence by spending US$4 million and has the option to spend up to a further US$4 million by 17 February 2024 to earn an additional 19% interest in the licence. The Company also has several interests and royalties in companies operating in East Africa and Turkey that could deliver future cash flow.
