West African-focused gold explorer Predictive Discovery (PDI) has further extended the known mineralised zones at its Bankan project in Guinea.
Positive results
An extensive power auger drilling program has been conducted across four sites at Bankan.
The NE Bankan mineralised zone has been extended from 1.3 to 1.6 kilometres in length with an extension to the north.
Two new high-grade gold targets have also been identified. One sits just to the south-west of NE Bankan, the other is further to the south-east and sits in the Saman permit area.
The new zone to the south-west of NE Bankan is the most compelling, as it seems to indicate a potential parallel gold mineralised structure alongside NE Bankan.
Predictive is planning a drilling program to test the suspected structure when the rainy season ends around October.
The SE Saman prospect yielded two high-grade gold intersections, and identified a 600-metre long, east-west orientated auger anomaly which will be followed up with further auger and reverse circulation (RC) drilling.
While the auger drilling is quite shallow — to depths of just 20 metres — and the company is not including four metres of topsoil in the results, there have been a number of highly positive intercepts across the targeted areas.
The NE Bankan extension yielded a best intercept of 16 metres at 3.9 grams per tonne (g/t) gold, while the SE Saman target was even better with 16 metres at 4.2 g/t gold.
Predictive Managing Director Paul Roberts says revised exploration methods have yielded more positive results across Bankan.
“The low gold values observed in the top four metres (which [is] immediately followed by continuous well mineralised gold zones) suggest that there is a transported component in the shallow lateritic material,” Paul said.
“[This means] that past surface soil sampling or mapping of artisanal gold sites has been ineffective in exploring the full extent of such gold mineralisation, and that substantially more systematic auger drilling will be required to fully define the area’s potential,” he added.
Next steps
Programs of power auger, RC and diamond drilling will recommence across Bankan in October.
Auger drilling will target both the anomaly parallel to NE Bankan and the SE Saman anomaly.
RC drilling will test the new 300-metre extension to the north of NE Bankan, and will later test the new auger target areas once they’ve been defined.
The company is also waiting on results from recent and current drilling, which will shed further light on existing and new target areas.
Predictive Discovery is down 2.8 per cent to seven cents as at 12:05 pm AEST.
