Predictive Discovery Ltd (ASX:PDI) has tabled the latest batch of drilling assays from the Bankan Gold Project in Guinea, where it has unearthed strong regional gold results that enhance the project's multi-deposit potential.
The regional campaign chased up 10 structural targets defined by an aeromagnetic survey last year, along with other geochemical targets within 3 kilometres of the NE Bankan deposit.
Follow-up aircore drilling has returned strong gold intersections on four prospects so far: the 800W, SW Bankan, Bankan Creek North and AG2 targets. All are open along strike and at depth and require follow-up deeper drilling.
Ultimately, the latest assays continue to grow Bankan’s multi-deposit potential, firming up what Predictive considers to be a growth-centric gold target.
Expected to bolster resource inventory
Speaking to the findings in an ASX announcement on Wednesday, Predictive executive director Paul Roberts said Bankan was at “a very exciting stage”.
“Adding to the ongoing, deep drill success at NE Bankan, aircore drilling of the Bankan regional prospects continues to identify new, highly encouraging zones of gold mineralisation.
“With further drilling and the improved geological understanding that flows from that, these prospects are expected to add significantly to the Bankan Project’s mineral resource inventory.
“Near NE Bankan, at 800W, new drill results have identified a broad zone of shallow, ENE-trending gold mineralisation which is open along strike and at depth.
“Further to the north, on the AG2 prospect, new zones of gold mineralisation have emerged in several separate locations, some on structurally controlled contacts with mafic rocks.
“All of the previously discovered prospects and new discoveries require follow-up aircore and reverse circulation (RC) drilling while ongoing auger drilling continues to test new structural positions with the aim of uncovering yet more new gold mineralised zones.”

The results are in
Aircore drilling across Bankan’s regional targets yielded what the company has described as “highly encouraging” results.
Assays from the four prospects of interest include:
800W -
- 22 metres at 1.4 g/t gold from 24 metres;
- 12 metres at 10.5 g/t from 5 metres, including 2 metres at 57 g/t from 8 metres; and
- 6 metres at 1.7 g/t from 42 metres, including 2 metres at 4.5 g/t from 44 metres.
Bankan Creek North (N-BCK) -
- 8 metres at 9.9 g/t from 0 metres, including 6 metres at 13 g/t from 0 metres.
AG1 -
- 8 metres at 1.7 g/t from 12 metres, including 6 metres at 2.2 g/t from 12 metres; and
- 8 metres at 1.2 g/t from 12 metres, including 6 metres at 1.5 g/t from 12 metres.
AG2 -
- 6 metres at 10.5 g/t from 26 metres, including 2 metres at 15.1 g/t from 28 metres;
- 4 metres at 5.3 g/t from 2 metres, including 2 metres at 10.2 g/t from 4 metres;
- 4 metres at 5.0 g/t from 22 metres, including 2 metres at 9.6 g/t from 22 metres;
- 12 metres at 0.9 g/t from 6 metres, including 2 metres at 3.1g/t from 12 metres; and
- 31 metres at 0.8 g/t from 16 metres (mineralised to endof-hole).
Next up
Predictive plans to follow through with aircore and RC drill programs, supplemented by diamond drilling on important prospects to follow up the new gold discoveries.
Auger drilling remains ongoing, with two rigs testing structural targets.
Predictive’s full technical team — including country manager Aime NGanare, new geology manager Norm Bailie and chief geologist Dr Barry Murphy — will be working with managing director Andrew Pardey and executive director Paul Roberts in the field in February-March.
From here, they’ll develop detailed plans to accelerate exploration on the Bankan Project, both on the known deposits and these emerging gold discoveries.
