Predictive Discovery Ltd’s (ASX:PDI) drill results from seven reverse circulation (RC) holes at Bankan Gold Project in Guinea have returned broad intersections including high gold grades with the NE Bankan prospect width extended to 300 metres.
Shallow oxide drilling at NE Bankan continues to return broad intersections including high-gold grades with better results:
- 51 metres at 2.5 g/t gold from 2 metres, including 1-metre at 76.8 g/t from 43 metres;
- 54 metres at 2.1 g/t from surface, including 3 metres at 11.2 g/t from 14 metres;
- 9 metres at 2.4 g/t from surface, including 1-metre at 18.5 g/t from 5 metres and 17 metres at 2.6 g/t from 29 metres, including 3 metres at 10.0 g/t from 30 metres; and
- 36 metres at 1.8 g/t from 3 metres and 37 metres at 1.0 g/t from 44 metres.
These results have confirmed that oxide gold mineralisation extends over a horizontal width of 300 metres and is predominantly mineralised down to the base of oxidation at vertical depths of 40 to 65 metres.
The drilling also demonstrates the continuity of broad zones of gold mineralisation from surface down into fresh rock.
“Exceptionally impressive" grades
Predictive Discovery managing director Paul Roberts said: “These new results expand our detailed drill coverage of the shallow oxide gold mineralisation 80 metres to the north of the previously reported oxide-gold drill coverage.
“The horizontal extent of gold mineralisation is even wider than the mineralisation seen on the next section to the south and the gold grades and widths in individual holes continue to be exceptionally impressive.
“The deeper holes on this section also demonstrate clear continuity from the near surface through to previously drilled strong intercepts in fresh rock (eg KKODD011 – 55 metres at 2.9 g/t gold).”

Ongoing work programs
Three rigs are completing RC and diamond drilling programs designed to support a maiden resource estimate planned for mid-2021 with metallurgical test-work scheduled to begin in April 2021.
The focus of the current power auger program is to search for gold mineralisation beneath significant artisanal workings in the Argo permit, which is around 20 kilometres to the north of NE Bankan.
The company is completing processing and interpretation of the recently acquired aeromagnetic survey which has already identified a number of structures and targets to the north and south of NE Bankan as it searches for additional gold discoveries within the project area.
Once complete, geological mapping and auger drilling will be used to explore those targets.
