    Predictive Discovery intersects further high-grade gold at Bankan

    Predictive Discovery Limited (ASX: PDI) announced that multiple wide gold intersections including 1m @ 187.5g/t Au were returned from shallow oxide and deeper drilling at the Bankan Gold Project in Guinea.

    Best results included 45m @ 5.4g/t Au from 65m, incl. 1m @ 187.5g/t Au; 65m @ 2.7g/t Au from 47m, incl. 7m @ 9.8g/t Au, and 1m @ 13.6g/t Au, and 2m @ 8.2g/t Au.

    Two greenfield gold discoveries at Bankan

    The company had made two significant greenfield gold discoveries at Bankan over the past 11 months – at the NE Bankan prospect and Bankan Creek.

    At the NE Bankan prospect, the first phase of drilling had outlined a 1.6km-long zone of shallow gold mineralisation, now with steadily increasing RC/DD drill coverage at depth. Bankan Creek is a satellite discovery 3km to the west of NE Bankan that was only lightly tested but which bears the hallmarks of a strong gold mineralised system.

    Drilling at Bankan

    The company had recently commenced shallow oxide and deeper drilling at Bankan.

    The RC oxide program tested a very broad, long zone of shallow oxide gold mineralisation in deeply weathered bedrock. The company said that the first three completed lines of oxide RC drilling confirmed the continuity and broad widths of the oxide gold mineralisation in the upper 50-70m of the central NE Bankan zone.

    The company said that this shallow oxide zone has now been confirmed by west to east RC drilling on four cross sections over an average width of approximately 200m.

    The deeper RC/DD program at NE Bankan was designed on an 80 x 80m spacing in the west dipping plane of the gold mineralisation and was testing the extent of the gold to a vertical depth of at least 250m in the fresh rock. The company said that the new intersections continue to confirm broad widths and good grades down to 200m vertical depth.

    High-grade results from NE Bankan

    PDI reported encouraging results from the 3 completed diamond holes (BNERD0007, BNERD0020, and BNERD0021) and 9 RC-holes (BNERD0031 and BNERD0035-43) from both the central zone oxide program and the step-out deeper drilling program.

    These were drilled as part of the 25,000-meter drilling program currently underway with the aim of delivering an initial resource in mid-2021. The company said that the drill samples were assayed by fire assay at SGS in Bamako (Mali).

    Best results at NE Bankan included 45m @ 5.4g/t Au from 65m, incl. 1m @ 187.5g/t Au; 65m @ 2.7g/t Au from 47m, incl. 7m @ 9.8g/t Au, and 1m @ 13.6g/t Au, and 2m @ 8.2g/t Au; 19m @ 4.8m Au from 178m, incl. 6m @ 13.7g/t Au; 10m @ 4.0g/t Au from 141m, incl. 4m @ 7.7g/t Au; and 74m @1.3g/t Au from 6m, incl. 2m @ 10.1g/t Au.

    Further work

    The company said that following receipt of results from the ongoing RC and DD drilling program, infill drilling will be carried out to support the Maiden Resource Estimate planned for mid-2021. The company said that metallurgical test work is scheduled to begin in April 2021.

    In addition to the ongoing RC and Diamond drilling, power auger drilling has been in progress since October last year to search for gold mineralisation in the areas around Bankan West, Bankan Creek, and NE Bankan. PDI said that once results from the recently completed aeromagnetic survey are assessed, auger programs will be extended further to the north and south in the search for new satellite gold discoveries.

    Predictive said that geological studies will continue to be conducted to characterise the gold mineralisation going forward.

    Management comments

    Predictive Discovery Managing Director Paul Roberts said: “The latest results strengthen our belief that NE Bankan has all the hallmarks of a plus-million ounce gold system, with broad zones of gold consistently intersected over a growing strike length.

    The presence of some extremely high grades in these new results also speaks to the strength of the gold mineralised system. With highly encouraging drill results also being received from other prospects in the area, the potential for a multi-million-ounce resource inventory across the Bankan Project is increasing with every new set of results.

    Infill hole BNERD0007 suggests a flattening of the gold mineralised structure with depth, highlighted by an intersection of 19m @ 4.8 g/t from 178m. If a similar flattened dip is observed at depth on adjacent cross-sections, the volume of mineable gold within a potential future open pit mine may be significantly expanded.”
