Final Results from Phase 5 Drilling at the Bibemi Gold Project in Cameroon

 

Oriole Resources PLC (AIM: ORR), the AIM-quoted gold exploration company focused on West and Central Africa, is pleased to provide an update on its 90% owned Bibemi orogenic gold project ('Bibemi' or the 'Project') in Cameroon, where a Phase 5 drilling programme has recently been completed for approximately 6,900 metres ('m') in 56 holes at the Bakassi Zone 1 prospect ('Bakassi Zone 1' or 'BZ1' - announcement dated 13 February 2025).

The programme was fully funded by BCM International ('BCM'), which has acquired an initial 10% interest and is earning up to a further 40% interest by spending up to US$4 million on exploration.  Bibemi currently has an Inferred Mineral Resource Estimate ('MRE') of 375,000 ounces ('oz') contained gold ('Au'), grading 2.30 grammes per tonne ('g/t') gold, which was announced in January 2024, based only on drilling data from Phases 1 to 4 and a US$2,000/oz Au gold price.  This MRE will now be updated to include data from the Phase 5 drilling programme and using an appropriate gold price.

Highlights

 

·    Phase 5 drilling programme recently completed over three sub prospects: BZ1-MRE, BZ1-NW and BZ1-SW.  At BZ1-MRE, drilling has reduced drill fence line spacing to around 50m over the existing MRE main pit design.

·    Results for the final seven drill holes in the BZ1-MRE target (BBDD0103-109) show they are all mineralised, with a total of 49 reported intervals (using a 0.20g/t Au lower cut-off) including:

 

BBDD103

1.00m at 2.62g/t Au from 40.90m.

1.00m at 2.71g/t Au from 143.50m.

1.00m at 3.84g/t Au from 169.90m.

 

BBDD104

1.00m at 15.11g/t Au from 61.30m.

3.10m at 1.53g/t Au from 116.40m.

3.00m at 1.46g/t Au from 158.60m.

2.00m at 3.51g/t Au from 173.60m.

 

BBDD105

4.10m at 2.20g/t Au from 35.20m.

1.10m at 2.38g/t Au from 64.90m

 

BBDD106

1.00m at 3.93g/t Au from 145.30m.

4.00m at 1.71g/t Au from 161.50m.

 

BBDD107

3.10m at 1.30g/t Au from 52.40m.

1.10m at 4.34g/t Au from 92.20m.

 

BBDD108

1.00m at 1.43g/t Au from 61.40m.

1.00m at 2.01g/t Au from 158.10m.

BBDD109

2.20m at 8.11g/t Au from 122.90m.

2.00m at 2.50g/t Au from 132.00m.

 

 

·    The results, which all fall within the existing MRE pit shell design, have successfully demonstrated that the mineralisation continues between the existing fence lines, and that there is scope to expand and partially upgrade the resource to the Measured and/or Indicated Australasian Joint Ore Reserve Committee ('JORC') Code categories.

·    With Phase 5 complete, an independent structural review is underway to help refine the geological and mineralisation model.  This will give the key inputs for the next independent consultant's MRE upgrade using an appropriate gold price.  This should be completed in Q2 2025.

·    As part of the ongoing Exploitation Licence Application ('ELA') process, the Company has also submitted an updated Environmental and Social Impact Assessment ('ESIA') report and is about to complete more advanced metallurgical test work to determine the appropriate mineral processing flow sheet. 

 

Chief Executive Officer of Oriole Resources, Martin Rosser, said: "With the completion of Phase 5 drilling at Bibemi, which returned more encouraging gold intersections, we can now look forward to an updated independent consultant's mineral resource estimate, with scope to expand and partially upgrade it to the Measured and/or Indicated JORC Code categories.  Moreover, with the completion of important technical and other requisite studies, we expect to be able to advance significantly the Exploitation Licence Application lodged with the Cameroon Mines Ministry."

Further Details

At the 177 square kilometre ('km2') Bibemi orogenic gold project in the North region of Cameroon, 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 an approximately 12 kilometre ('km') long mineralised hydrothermal system at surface. 

 

Between 2021 and 2022, the Company completed four phases of diamond drilling at the Project for a total of 6,685.40m in 54 holes, with gold mineralisation hosted in both steeply dipping and flatter lying quartz and quartz-tourmaline veins.  The majority of that drilling was focused on an approximately 1km long section at the southern end of Bakassi Zone 1 where, in January 2024, the Company reported an MRE for the BZ1-MRE zone of 5.1 million tonnes grading 2.30g/t Au for approximately 375,000 oz Au contained in the 'JORC Inferred Resources category, based on a 0.45g/t Au lower cut-off grade and within a US$2,000/oz gold price open pit shell (announcement dated 15 January 2024).

 

In June 2024, a fully funded Phase 5 diamond drilling programme commenced at Bakassi Zone 1 to further test the BZ1-MRE zone, and two along strike targets, BZ1-NE and BZ1-SW, for a planned 7,060m in 62 holes.  The programme was completed in February 2025 for a total of 6,915.40m drilled in 56 holes, with 34 of these holes completed at BZ1-MRE (BBDD051A, BBDD055-080, and BBDD103-109), 14 holes drilled at BZ1-NE (BBDD081 - BBDD094), and 8 holes drilled at BZ1-SW (BBDD095-102).  Drilling at Bibemi now stands at approximately 13,600m in 110 diamond drill holes.

Previously reported intersections from this programme at BZ1-MRE include 4.10m at 7.99g/t Au (BBDD059), 2.70m at 14.67g/t Au (BBDD058), 2.00m at 12.50g/t Au (BBDD061), 2.15m at 9.95g/t Au (BBDD063), 2.00m at 8.57g/t Au (BBDD075) and 1.00m at 25.54g/t Au (BBDD068; announcements dated 12 September 2024, 14 October 2024, and 28 November 2024).  Several of these intersections fall outside the current mineralisation wireframes, but within the existing MRE open pit design, providing scope for additional near surface resources. 

Today the Company reports results for the final seven drill holes from the programme, with six of these holes being located on new infill fence lines within the existing MRE, reducing the fence line spacing to approximately 50m within the core zone of the mineralisation.  Results from holes on the new infill fence lines include 1.00m at 15.11g/t Au and 2.00m at 3.51g/t Au (BBDD104), 4.10m at 2.20g/t Au (BBDD105), and 2.20m at 8.11g/t Au and 2.00m at 2.50g/t Au (BBDD109).  Full results are presented in Table 1 below.

* Intervals greater than 1.00m, calculated using a 0.20g/t Au lower cut-off grade and no more than 34% internal dilution.  True widths are variable due to changes in vein orientation but are typically 77% of the reported downhole intersection.

 

These results, which all fall within the pit shell design of the existing MRE, have successfully demonstrated that the mineralisation continues between the existing fence lines.  The intersections predominantly fall within the existing mineralisation wireframes, although there are some intervals that fall outside of the existing wireframes, and within approximately 100m depth from surface.  This confirms the potential to expand and upgrade the existing MRE, with a particular focus on defining near surface contained gold.

An independent structural review is currently underway by consultant SEMS Exploration Services to help refine the geological and mineralisation model and provide the key inputs required for the next mineral resource estimate calculation.  This work should be completed later this month and thereafter an updated MRE will be prepared by independent consultant Forge International Limited and should be reported in Q2 2025. 

It is anticipated that the significant additional drilling completed at the project since the maiden MRE was completed will enable an expansion and partial upgrade from the JORC Inferred to JORC Measured and/or Indicated categories.  The estimate should also benefit from a more appropriate gold price.

As part of its ongoing ELA, the Company has also submitted an ESIA report, and is also about to complete more advanced metallurgical test work to determine the appropriate mineral processing flow sheet.
