- Gold explorer Predictive Discovery (PDI) has commenced phase two power auger drilling at its Bankan project in Guinea
- The drilling is targeting a western extension of the NE Bankan auger grid, to test a potential parallel mineralised zone to the main NE Bankan deposit
- Final assays have also been returned from the first phase, with results peaking at one metre at 11.6 grams per tonne (g/t) gold, and 36 metres at 1.0 g/t
- Phase one drilling and geophysics data are still being collated to generate further targets for phase two reverse circulation and diamond drilling, set to begin this week
- Predictive Discovery is trading 3.28 per cent lower for 5.9 cents per share
Gold explorer Predictive Discovery (PDI) has commenced phase two power auger drilling at its Bankan project in Guinea.
Final results from reverse circulation (RC) drilling at the NE Bankan gold mineralised zone have also been returned.
Phase two
The second phase of drilling at Bankan is targeting a western extension of the NE Bankan auger grid.
Previous drilling indicated a possible new north-south zone of gold mineralisation between the NE Bankan and Bankan Creek gold deposits, which will be tested in the new program.
Results from phase one RC and diamond drilling will also be collated to generate further targets for the phase two program.
Phase one results
Assays from the final seven RC holes of the Bankan-1 drilling program have been received, with results peaking at one metre at 11.6 grams per tonne (g/t) gold from a depth of 56 metres, and 36 metres at 1.0g/t from six metres.
Drilling was located at the northern end of the known Bankan mineralised zone, which extends across around 1.6 kilometres of strike.
The final results from NE Bankan indicate the presence of mineralisation in a shallow, west-dipping structure.
The results highlight the potential for more strike extensions in the undrilled, 300-metre-long northern section of the NE Bankan mineralised footprint and possibly beyond.
RC and diamond drilling are set to begin this week to probe priority targets, with a view to complete a maiden resource estimate by mid-2021.
PDI Managing Director Paul Roberts says the results so far bode well for future operations at Bankan.
“We are very pleased to have commenced the Bankan-2 drilling program with a test of a possible new zone of bedrock gold mineralisation between NE Bankan and Bankan Creek, and to follow up two excellent power auger drill results on the western edge of the NE Bankan auger grid which included 16 metres at 3.9g/t gold and 16 metres at 1.5 g/t gold,” Paul said.
“The final RC results from the Bankan-1 drilling program […] provide further useful additional information on oxide gold mineralisation near the current northern RC drill limit at NE Bankan,” he contunied.
“The very shallow dip of gold mineralisation that we see here suggests a very low waste/ore ratio in possible future mining of soft, oxide gold mineralisation in the area, which could drive strong mining economics,” Paul concluded.
Next steps
Ground magnetics indicate potential structural targets to the west of the known NE Bankan mineralised zone but further geophysics is in progress to refine the data.
Final analysis of the geophysics will be used to understand controlling structures and identify targets for drilling.
The targets generated will be collated with the phase one drilling data to define further priority zones for the phase two program.
Predictive Discovery is trading 3.28 per cent lower for 5.9 cents per share at 1:11 pm AEDT.
