Predictive Discovery Ltd (ASX:PDI) has hit up to 92 metres at 1.9 g/t gold in diamond drilling at the flagship Bankan Project in Guinea, demonstrating a large gold mineralised body which may contribute to a planned mineral resource estimate in mid-2021.
Results have been received for five diamond drill holes (DD) and two reverse circulation (RC) holes with diamond hole KKODD20 at Bankan Creek prospect intersecting broad mineralisation over a downhole length of 91.6 metres.
Best results within the 91.6-metre intersection from 56 metres were:
- 9 metres at 2.3 g/t from 69 metres;
- 43 metres at 1.8 g/t from 82 metres; and
- 16 metres at 4 g/t from 127 metres.
Based on this result and earlier RC drilling, gold mineralisation at Bankan Creek appears to be widening at depth and to the north.
The next phase of drilling at the Bankan Project is designed to test the full extent of Bankan Creek prospect, which is only 3 kilometres southwest of the main NE Bankan lode.
Results “strengthen project considerably”
Managing director Paul Roberts said: “Between April and September this year, the company has moved quickly from the initial discovery to completion of our inaugural drilling program, which consisted of approximately 23,000 metres of DD, RC and power auger drilling.
“With nearly all the drill results received, we have begun planning the next phase of exploration with the Bankan-2 drilling program scheduled to start in less than two weeks.
“The goals of the initial drill program were to outline NE Bankan’s shape and lateral extent and to start identifying and evaluating new gold mineralised zones.
“These new results strengthen the project considerably by confirming thick true widths along strike from earlier diamond drilling on NE Bankan and suggesting that the Bankan Creek mineralisation may be much more extensive than we had originally thought.”
Latest assays received at NE Bankan continue to identify wide zones of mineralisation both to the north and south of the earlier reported (west-to-east) DD holes particularly on the western side of the mineralised zone.
KKODD018, one of two west-to-east DD holes drilled south of the previously reported diamond drill results returned an average grade of 1.4g/t over 60 metres, with better intersections including:
- 13 metres at 1.4 g/t from 57 metres;
- 36 metres at 1.5 g/t from 74 metres; and
- 5 metres at 1.8 g/t from 112 metres.
More exploration required
Roberts continued: “What has also become clear is that we have just scratched the surface of the project and much more exploration is required to fully unearth its potential.
“As such, a new power auger drilling program is about to begin 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 deposits.
“We were already excited by high-grade auger drill results on the western margins of the NE Bankan auger grid and have been further encouraged with identification of previously unknown, new artisanal gold workings north-west of the mineralised auger holes.
“With a 3-kilometre wide untested zone between Bankan Creek and NE Bankan and 35 kilometres of largely unexplored strike length within Predictive’s ground to the north and south of the two prospects, the potential to expand the extent of gold discoveries further across our permits is enormous.”
A review of drilling data from Bankan-1 is underway and will be used to obtain further insights into geological structures controlling the NE Bankan and Bankan Creek mineralisation and help design DD and RC drill holes for the upcoming Bankan-2 drilling program, which is planned to start on October 22.
The first element of the Bankan-2 power auger drilling will begin shortly, following up the recent strong power auger results 1-kilometre southwest of NE Bankan and recently recognised artisanal workings 500 metres to the northwest.
Predictive will continue its aggressive exploration of the NE Bankan and Bankan Creek prospects and the large area of unexplored permit areas over the next six months as it continues to advance towards a maiden resource estimate, due mid-2021.
