Initial results for Bibemi were reported in March after rock-chip sampling results were announced in November, demonstrating high-grade gold anomalism of up to 135.4g/t gold, extending over a 4km strike.

 

The newest results include a best intersection of 9m at 3.14g/t Au towards the northern extent of the central Bakassi zone. 

 

"Within this is a higher-grade interval of 13.12g/t gold over 2m, which correlates-well with multiple bonanza grade rock-chip samples yielded from nearby quartz veins," Oriole said. 

 

Other highlights include 1m at 4.53g/t gold; 16m at 0.5g/t, 2m at 1.27g/t and 2m at 0.84g/t; 2m at 1.58g/t; 1m at 2.27g/t; 2m at 0.92g/t and 1m at 0.56g/t; 2m at 1.28g/t; and 3m at 0.75g/t.

 

The company said geological mapping and structural analysis of the quartz veins had identified two main gold-mineralised sets, both of which were tourmalinised.

 

It added that initial screen metallics fire assay on coarse rejects had indicated the presence of coarse gold in the samples was not impacting the total gold content, with further testwork underway.

 

Oriole is also carrying out a number of technical studies, including geophysical interpretation of regional data, thin section petrography and x-ray diffraction analysis of key lithologies.

 

It has completed phase two infill trenching at Bibemi for 3,504m for 11 trenches, with results expected late in the September quarter.

 

CEO Tim Livesey said the second batch of phase one trenching results from Bibemi had continued to support an orogenic gold model, and interrogation and interpretation of the data had identified two main mineralised vein trends to date. 

 

"We are currently undertaking a range of technical studies ... This will move us one step closer to designing a targeted drilling programme to test the prospective central Bakassi area - the main focus of our field work to date - during the next dry season, commencing in October 2019," he said. 

 

Meanwhile, the company has completed phase one infill soil sampling at the nearby Wapouzé gold project, with results for a 639 soil samples and 123 rock-chip samples expected later in the June quarter. 

 

"This data will assist us in designing the next programme of work at Wapouzé, which will include detailed geological mapping and trenching over the key anomalous zones (more than 12km strike identified to date), and will ultimatly lead us to the identification of drill targets," Livesey said.

 

The company is earning up to a 90% interest in Bibemi and Wapouzé.

 

Oriole shares (AIM:ORR) gained 1.49% on Tuesday to 0.34p (US0.43c), down from 0.42p at the start of the year.
