DANDOKO PROJECT - SEKO DRILLING
Assay results from 118 AC (for 10,342m), 7 RC (for 1,252m) and 1 DD (for 258m) drill holes at Seko have now been received.
The shallow AC holes were designed to explore for blind mineralisation between the three main Seko gold trends (SK1-3) and for extensions along strike (Figure 3). As part of this program, two long AC traverses were completed across the Seko gold trends with the holes drilled in a 'heel-to- toe' manner at -55° to an average downhole depth of 88m (vertical depth ~69m). The RC holes were designed to follow up previous mineralisation with several holes not reaching target depth due to ground conditions.
The significant drill hole intersections are summarised in Table 1. All drill hole locations are summarised in Table 2 and are graphically represented in Figures 3 to 5 and 7.
The AC traverses returned a number of significant results to the west, south and east of SK1. To the immediate west, 4m at 14.12g/t gold (including 2m at 27.40g/t gold) was intersected from 48m related to a potential blind zone of gold mineralisation that was undetected in the earlier auger geochemical drilling. To the immediate south and southwest of SK1, the AC holes returned several medium to high-grade intersections, including 2m at 9.15g/t gold, 4m at 2.01g/t gold and 2m at 2.93g/t gold, warranting further investigation.
Significantly, a step-out AC traverse located 600m south and along strike from SK1 intersected a 16m zone of low grade gold mineralisation (averaging 0.82g/t gold) that included 4m at 1.38g/t gold (Figure 5). This intersection may be related to a potential linking structure between SK1 and the Sory prospect, located some 1.2km to the south. This trend will be further investigated by reconnaissance AC drilling following the wet season.
RC hole RCSK19-082, located on the eastern side of SK1, intersected multiple zones of significant gold mineralisation, including 10m at 2.33g/t gold, 2m at 7.13g/t gold and 3m at 2.30g/t gold. The hole failed to reach the target depth and was subsequently redrilled. The RC pre-collar (hole RCSK19-083) encountered lower grade zones of gold mineralisation, including 9m at 2.73 g/t gold. The hole was completed to its target depth of 258m by diamond core (hole RDSK19-47), which intersected a shear zone within chloritised sediments hosting minor pyrite mineralisation without any significant associated gold mineralisation.
The two RC holes (holes RCSK19-084 & 085) completed 300m along strike to the north of SK2 confirmed a new gold target. Both holes intersected a significant zone of altered breccia with sulphide mineralisation hosting gold mineralisation grading up to 4.61g/t gold over 1m along with wider zones of anomalous gold mineralisation (up to 17m at 0.80g/t gold). The Company is highly encouraged by the discovery of further altered breccia, which has strong similarities to the main zone of gold mineralisation at SK2. Previous shallow reconnaissance AC drilling at this locality had returned 11m at 1.79g/t gold, including 2m at 5.01g/t gold1.
The AC traverses successfully intersected further gold mineralisation on the eastern side of SK3, including a best intersection of 10m at 1.37g/t gold, including 2m at 4.47g/t gold. The two RC holes drilled in the north of SK3 encountered several narrow zones of gold mineralisation, including a best intersection of 1m at 16.40g/t gold.
