Predictive Discovery Limited (ASX: PDI) has announced high-grade hits including 26m at 17.5g/t gold from 58m from the RC drilling completed on the southern section of the North-East Bankan gold mineralised system within the Company’s flagship Kaninko Project in Guinea.
The company reported that assays were received from 8 RC drill holes, yielding several outstanding, high-grade and wide gold intercepts.
Significant intersections include 26m at 17.5g/t gold from 58m (to end of hole), including 6m at 49.9g/t gold from 59m, 2m at 8.6g/t gold from 72m, and 6m at 17.3g/t gold from 78m (to end of hole); 35m at 2.4g/t gold from 1m, including 4m at 13.6g/t gold, and 36m at 2.2g/t gold from 64m; and 67m at 1.7g/t gold from 32m, including 2m at 11.0g/t gold from 59m.
PDI said that the assays received have successfully expanded the known drilled gold mineralisation at NE Bankan to the south.
The company announced that a Diamond Drill (DD) rig will be mobilised to test the full width of the gold mineralised zone in the opposite direction, from west to east. PDI said that hole KKORC016, which recorded 26m at 17.5g/t gold from 58m, may also be extended further with diamond drilling.
Predictive said that two RC holes are pending to complete the southern line over the gold mineralised footprint as defined by earlier power auger drilling, with a further 21 RC holes and 1,168 power auger drill samples currently in the laboratory awaiting assay.
The Kaninko Project in Guinea was granted to Predictive in July 2019. Through rapid, targeted low-cost exploration, the Company has progressed it from a greenfields tenement with no known history of past exploration, to a property on which significant gold mineralisation has now been identified.
Significant prospects include Bankan Creek and North-East Bankan Prospect.
Drilling at Kaninko
In January-February 2020, the Company completed 3,178m of shallow power auger drilling and 490m of trenching at Kaninko, with better results including 11.90g/t gold from bottom-of-hole Power Auger sampling at the NE Bankan Prospect and 18m at 1.60g/t gold from trenching at the Bankan Creek Prospect.
During March 2020, the Company completed 24-holes (totalling 1,193m) of angled AC/RC drilling at NE Bankan along seven traverses, testing beneath the better intercepts from the previously announced power auger results.
This produced impressive results from most drill holes including 46m (to EOH) at 6.58g/t gold from 4m including 10m at 26.52g/t gold from 34m; 42m (to EOH) at 2.92g/t gold from 8m; 50m (to EOH) at 1.53g/t gold from surface including 20m at 2.51g/t gold from 30m; 42m at 1.56g/t gold from surface including 30m at 2.07g/t gold from 12m; 20m at 1.35g/t gold from surface; 50m (to EOH) at 1.27g/t gold from surface; 34m at 1.06g/t gold from surface; and 48m at 1.15g/t gold from surface.
The Company is currently undertaking a fully funded follow-up drilling program focused on the recent discovery at NE Bankan consisting of a planned 25,000 metres of RC drilling, 5,000 metres of diamond drilling (DD), and 20,000 metres of auger drilling.
Mineralisation at NE Bankan comprises an approximate 1.3km-long coherent auger gold trend with AC/RC confirming a zone approximately 100-200m wide in the mineralised sections tested so far. The evaluation of the NE Bankan discovery is ongoing.
Predictive has now reported the receipt of first assay results from RC drilling completed on the southern section of the NE Bankan gold mineralised system.
High-grade assays from NE Bankan
PDI announced that RC drilling at NE Bankan was completed on three lines, between 80-240m south of Air-Core (AC) discovery hole KKOAC001, which had returned 46m at 6.58g/t gold.
Predictive said that the reverse circulation program was undertaken by Target Drilling. All the drill chips were assayed in 1m intervals, with the samples analysed by fire assay at the SGS laboratory in Bamako, Mali.
The company reported that assays received from 785m of RC drilling (8 holes, KKORC013, KKORC014, KKORC015, KKORC016, KKORC017, KKORC018, KKORC019, and KKORC020) have successfully expanded the known drilled gold mineralisation at NE Bankan to the south, yielding some of the strongest results to date at NE Bankan, including high-grade gold intercepts in multiple holes.
Significant intersections include KKORC016: 26m at 17.5g/t gold from 58m (to end of hole), including 6m at 49.9g/t gold from 59m, 2m at 8.6g/t gold from 72m, and 6m at 17.3g/t gold from 78m (to end of hole); KKORC013: 35m at 2.4g/t gold from 1m, including 4m at 13.6g/t gold, and 36m at 2.2g/t gold from 64m; and KKORC017: 67m at 1.7g/t gold from 32m, including 2m at 11.0g/t gold from 59m.
The complete results reported are as shown below.
PDI said that the RC holes were drilled to a maximum downhole depth of 100m, however hole KKORC016, which recorded the highest-grade intercept of 26m at 17.5g/t gold, was stopped at 84m, 16m short of the target 100m depth because of hard rock slowing drill progress. The last metre sample (83-84m) assayed 6.2g/t gold.
Predictive said that some damp to wet samples have been obtained in this drilling program including in the upper part of the very high-grade gold intercept reported for hole KKORC016 (26m at 17.5g/t gold). PDI noted that high grades were also obtained from dry samples in the bottom 13m of that hole, including individual 1m grades of 36.5 g/t gold and 33.0g/t gold.
Latest updates and further work
PDI said that results are pending from two RC holes drilled to complete the southern line over the mineralised footprint. The company reported that a further 21 RC holes and 1,168 power auger drill samples are also currently in the laboratory awaiting assay.
The company reported that the large RC drill program is still ongoing at Kaninko. PDI said that diamond drilling is also being conducted to test the NE Bankan gold mineralised system at greater depth.
Predictive’s Managing Director Paul Roberts said: “These are exemplary results which demonstrate significant, broad and high gold grades over at least 160m of strike south of the southernmost drilled line reported to date. We are very pleased with the very high-grade gold intercept in hole KKORC016, which ended in mineralisation at 84 meters downhole.
A diamond drill rig will soon test beneath this mineralisation in the opposite direction – from west to east – which will allow us to test the western extent of the mineralisation and obtain a better idea of the width of the gold mineralisation on the new southern cross sections reported here.
We look forward to reporting the remaining RC assay results and commencing the deeper drilling on the southern portion of the NE Bankan mineralisation in what is shaping up to be a very exciting period for the Company in advance of moving towards a systematic drill-out of the NE Bankan gold discovery.”
