The Dandoko Project covers 134km2 within the Kenieba Inlier of west Mali in close proximity to numerous world class gold deposits including B2Gold’s 5.15Moz Fekola gold project 30km to the west and Randgold’s 12.5Moz Loulo Gold Mine 50km to the north-northwest.
Dandoko is underlain by Proterozoic Birimian meta-volcanic and meta-sedimentary sequences. A series of dominant NNE-trending faults, displaced by a second set of ESE-trending faults, have been mapped or interpreted from aeromagnetic data. Oklo considers that the NNE-trending structures are splays emanating from the Senegal-Mali Shear Zone (“SMSZ”), a regional NNW-trending strike-slip fault that plays an important role in controlling gold mineralisation in the region. The SMSZ is extensively mineralised and hosts no fewer than six major gold deposits for an endowment estimated at greater than 40Moz, including Sadiola (13.5Moz) and Loulo (12.5Moz).
Seko Prospect
The Seko prospect is a new discovery by Oklo Resources of five mineralised gold trends with significant gold potential. The prospects were identified after a systematic auger drilling program completed in February 2017 delineated over 6km of anomalous strike length on four trends spaced 500 to 750m apart.
Follow up aircore drilling on an initial 9 traverses returned significant gold in all
5 Seko anomalies including:
- 54m at 1.37g/t gold from 0m
inc 24m at 2.02g/t gold from 12m - 35m at 1.86g/t gold from 55m
inc 15m at 3.02g/t gold from 64m - 13m at 2.27g/t gold from 23m
- 18m at 2.01g/t gold from 55m
Diabarou Prospect
The Diabarou gold-in-soil anomaly covers an area of 1.2km north-east x 1.0km east-west. Artisanal workings within the northern portion of the anomaly have revealed gold-bearing quartz veins of up to 3m in thickness extending over 600m.
Previous drilling was restricted to the fringes of the artisanal workings and returned significant intersections of 12m at 1.50g/t gold and 20m at 1.44g/t gold in 2013. A total of 45 in-situ samples collected from the base of the artisanal workings returned numerous high grade gold results (up to 68.3g/t gold).
Further RC drilling of the artisanal workings commenced in late 2015 and to date has returned several outstanding intersections, including:
- 29m at 10.42g/t gold;
- 6m at 53.77g/t gold;
- 3m at 110.3g/t gold;
- 28m at 3.90g/t gold;
providing support for the prospect’s open pit potential.
