Predictive Discovery starts second phase of Bankan Gold Project drilling

The company has received the final reverse circulation results from the NE Bankan gold mineralised zone and a review of drilling data is underway.

Predictive Discovery Ltd - Predictive Discovery starts second phase of Bankan Project drilling
A maiden resource estimate is targeted for mid 2021

Predictive Discovery Ltd (ASX:PDI) has started the second phase of a drilling program at the Bankan Gold Project, with power auger drilling underway at the flagship project in Guinea.

The power auger drilling is being conducted on a western extension of the NE Bankan auger grid, testing a possible new north-south zone of gold mineralisation between the NE Bankan and Bankan Creek gold deposits.

Strong mining economics potential

Managing director Paul Roberts said: “We are 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.

“The very shallow dip of gold mineralisation that we see from the Bankan-1 drilling program 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.

“We look forward to drilling a series of high-priority targets in the Bankan-2 drilling program and providing regular updates in the months ahead as we advance the project towards a maiden mineral resource estimate by mid-2021.”

Final results from Bankan-1

Assays from the final seven holes of the Bankan-1 drilling program have been received, where drilling was conducted at the northern end of the mineralised zone.

Better results include:

  • 1-metre at 11.6 g/t from 56 metres;
  • 36 metres at 1 g/t from 6 metres;
  • 10 metres at 1 g/t from 8 meres;
  • 14 metres at 0.8 g/t from 36 metres; and
  • 9 metres at 1.6 g/t from 89 metres.

Review of drilling data

A review of drilling data from the Bankan-1 program is underway, delivering insights into geological structures controlling the NE Bankan and Bankan Creek mineralisation.

The Bankan-2 RC and diamond drilling programs, which are scheduled to start later this week, are designed to provide the framework for a maiden resource estimate targeted for mid-2021.

Further evidence of strike extensions

Final assay results from NE Bankan have provided further evidence of the presence of mineralisation to the north of the known mineralised zone.

RC drilling was undertaken in the northern area of the power auger footprint where previous drilling results showed that gold grades strengthened to the north in holes KKRC0063-KKRC067 with drilling identifying the presence of shallow west-dipping gold mineralisation.

The new results have added more information about this northern area, particularly on line 1,175,900N, and highlight the potential for more strike extensions in the undrilled 300-metre-long northern section of the power auger defined gold mineralised footprint and possibly beyond.

Drilling was undertaken by Bays Drilling and the samples analysed by fire assay at the SGS laboratory in Bamako, Mali.

Next steps

A review of all drilling data from Bankan-1 will be used to provide further insights into geological structures controlling NE Bankan and to design the Bankan-2 program as the Company gears up to deliver its Maiden Resource Estimate, due mid-2021.

The Bankan-2 RC/DD program is due to start later this week.

Results received from ground magnetics depict potential structural targets to the west of the known NE Bankan mineralised zone but provide incomplete coverage - further geophysics is in progress to understand and identify targets for drilling.
