Predictive Discovery announces Bankan Gold assay results

Published by , Editor
Global Mining Review,

Predictive Discovery Limited has announced assay results from the current diamond drilling (DD) and reverse circulation drilling (RC) campaign from its Bankan Gold Project, located in Guinea. The current drilling campaign is targeting resource growth down-plunge and along strike whilst also conducting infill drilling. The results to date indicate that the high-grade zone remains open at depth as shown below in the highlights.

Bankan currently has an inferred resource of 72.8 million t at 1.56 g/t gold (Au) for 3.65 million oz of Au. Deep drilling at NE Bankan is targeting the plunge extension of the high-grade shoot with an updated resource statement due 3Q22.

There are currently nine active drill rigs on site with three DD, two multipurpose DD/RC, one RC, one aircore and two power auger drill rigs, all conducting various resource development and exploration programmes across the Bankan Project.


  • DD holes (totalling 2164 m), including the deepest hole completed at NE Bankan has returned:
    • BNERD0113: 24 m at 5.5 g/t Au from 850 m, including 11 m at 10.3 g/t Au from 852 m.
      • BNERD0113 is the deepest intercept recorded to date, approximately 630 m down dip and 370 m vertically below the bottom of the 2021 maiden resource estimate (MRE) US$1800/oz pit shell.
    • BNERD0115: 27.6 m at 5.2 g/t Au from 389 m, including 6.2 m at 12.1 g/t Au from 394 m, and 1.7 m at 8.3 g/t Au from 414 m.
    • BNERD0116: 41 m at 3.8 g/t Au from 556 m, including 16.4 m at 7 g/t Au from 558 m, and 1 m at 11.2 g/t Au from 622 m.
  • Initial shallow RC grade control programme at NE Bankan, with six RC-holes (totalling 423 m) reported below:
    • BNERC0085: 4 m at 1.3 g/t Au from 4 m.
    • BNERC0086: 13 m at 0.9 g/t Au from 1 m.
    • BNERC0087: 6 m at 1.2 g/t Au from 3 m.
    • BNERC0088: 2 m at 4.1 g/t Au from 32 m.
    • BNERC0089: 9 m at 2.9 g/t Au from 7 m, including 2 m at 7.6 g/t Au from 12 m.
    • BNERC0090: 22 m at 1 g/t Au from surface.

The new intercept of 24 m at 5.5 g/t Au reported from BNERD0113 is the deepest intercept recorded to date and further extends mineralisation a further 300 m downdip. This is approximately 630 m down dip and 370 m vertically below the bottom of the 2021 MRE US$1800/oz pit shell.

BNERD0115 is infilling the resource between BNERD0086 and BNERD0097 to infill a 190 m gap and allow an inferred resource classification to link across these intercepts on this section.

BNERD0116 is targeting the local resource continuity on sections immediately north of the 41 m at 5.21 g/t Au in BNERD0105 and 14 m at 6.77 g/t Au in BNERD0106B. BNERD0113, BNERD0105, BNERD0106B and BNERD0116 confirm the steepening plunge of the high-grade shoot with depth and draws a clear 3D plunge-line for follow-up drill targeting to infill the high-grade zone down plunge.

A detailed 10 x 10 m angled RC grade control programme is also underway to investigate the short-range variability on the mineralisation within the upper fresh and oxide expression of the high-grade shoot and NE Bankan.

A total of 162 holes, approximately 80 m deep, angled at -55° to 090 azimuth are being drilled between 1175020N and 1175100N.

There are nine sections of 16 holes, each 10 m apart. Results for the first six holes are reported herein. One RC rig and one multi-purpose rig are dedicated to the angled RC grade control programme which is expected to be completed in early 3Q22.

Managing Director, Andrew Pardey, commented: “NE Bankan continues to confirm its emerging Tier-1 status with Hole BNERD0113, our deepest hole drilled to date, extending mineralisation a further 300 m down dip of the deepest previously completed hole and intersecting wide zones of good to high-grade gold mineralisation. As well as testing the high-grade shoot, close-spaced and shallow grade control RC drilling has also commenced at NE Bankan to help develop the resource model and contribute to mining studies.

“With the recently completed placement, Predictive is now fully funded to complete not only high-impact drilling programs that add significant ounces to our already large and growing resource base, as well as progress key development and baseline environmental studies.”
