Predictive Discovery Limited (ASX: PDI) has announced ‘bonanza’ gold grades from 4 diamond drill holes totalling 1,033m at its Bankan Project in Guinea.
High to bonanza gold grades were intersected across broad widths during drilling at NE Bankan, with gold grade and consistency improving with depth. Highlights include:
- Hole BNEDD0088: 49.7m @ 11.7g/t Au from 301m, including:
- 17.0m @ 31.9g/t Au from 313m (including 7.0m @ 50.3g/t Au)
- Hole BNEDD0087: 55.6m @ 5.7g/t Au from 237m, including:
- 40m @ 7.3g/t Au from 239m
The company said that the results reveal a ‘high-grade’ core zone 100-200m long, extending down-dip for over 250m and open at depth.
Up next at Bankan
With resource drilling now complete, the maiden resource drilling program includes one further deep DD drill hole to the south of the known deep gold zone, which will test the inferred southerly plunge location of the plus 100g*m gold mineralised contour. Assays for this hole have yet to be received.
One multipurpose RC diamond drill rig is now on site and has already started drilling a deeper hole beneath BNEDD0086. This rig will be used to conduct both deeper holes and infill drilling within the inferred high-grade zone.
The Company is currently working with a Senegalese drill contractor to supply a truck-mounted AC rig to the project site. During the wet season, this rig will be used to test the growing number of fresh targets defined by power auger drilling across the Project over the previous nine months.
“Following up our recent, previous best-ever intercept of 44m at 8g/t Au1 with a significantly broader and higher-grade gold intercept 100m to its north is simply remarkable”
Management comments
Predictive Discovery Managing Director Paul Roberts said: “Following up our recent, previous best-ever intercept of 44m at 8g/t Au1 with a significantly broader and higher-grade gold intercept 100m to its north is simply remarkable. Added to that, on the new drill section reported here, we can see a clear progression of both increasing grade and grade consistency as we drill deeper. Furthermore, with these new results, we now have a high-grade gold zone which is 100-200m long, extends down-dip for over 250m and, very promisingly, is open at depth.
Until now, NE Bankan has been shaping up as a large gold deposit with excellent geometry for a large-scale open pit mine. These new results have added a whole new dimension to the project as it now appears that the core of the deposit contains consistently higher grades in a zone which is expanding at depth. This offers clear justification for drilling deeper on this deposit.”
