Ø Exceptional high-grade drilling results returned:
o ZAAC0321: 5m at 270.5g/t gold from 4m, including 1m at 1,075g/t for 1m primary samples of previously announced 4m composite samples in AC drilling over the Ebilassokro target (reported at a 0.1g/t cut-off and maximum 1m of internal dilution).
o ZARC0013: 24m at 13.6g/t gold from 136m including 4m at 76.2g/t gold for 4m composite samples in RC drilling over the Ehuasso target (reported at a 0.1g/t cut-off and maximum 4m of internal dilution).
Ø Hole ZARC0013 confirms down-dip extension of high-grade mineralisation intersected in hole ZARC0009 (refer RNS of
Ø High grades returned in hole ZARC0013 confirm visible gold observed and reported in RNS of
Ø Additional visible gold observed from 82m to 83m and from 86m to 87m in hole ZARC0019, drilled at depth within the Ehuasso main target, with results pending.
Ø AC drilling now completed for the second phase programme with a total of 20,312m in 404 holes drilled.
Ø RC drilling ongoing at the main Ehuasso grid.
Commenting on the Company's latest progress,
"We are delighted that the ongoing drilling programme at the Ehuasso and Ebilassokro targets continues to define significant mineralised zones in the AC drilling and targeted deeper RC holes.
"The extremely high-grade results of 5m at 270.5g/t gold from 4m in hole ZAAC0321, including 1m at 1,075g/t (almost 35oz/t), for 1m primary samples of previously announced 4m composite samples, at the Ebilassokro target is very encouraging for a first phase drill programme on a new exploration target.
"Occurring at 4m depth downhole and relatively close to surface, the risk of contamination from transported material is recognised, however, geological logging of drill cuttings indicates the mineralisation occurs within quartz vein material, within a broader structurally defined soil anomaly, representing a high-priority target for follow-up.
"At the Ehuasso target, the results confirm the visible gold observed in hole ZARC0013 with an overall intercept of 24m at 13.6g/t from 136m depth downhole, which includes a higher-grade portion of 4m at 76.2g/t.
"These results are significant as they confirm high-grade mineralisation depth continuity below previously reported high-grade intersections in hole ZARC0009; with mineralisation now open from surface to a vertical depth of 125m.
"Additional visible gold has now been observed in quartz vein drill cuttings from hole ZARC0015 within the newly defined Ehuasso main target, confirming mineralisation continuity below recently reported AC drill intersections and at depth within the fresh material with assays pending.
"The AC component of the second phase drill programme has now been completed with 20,312m in 404 holes drilled, whilst RC drilling remains ongoing with our national team on the ground at the Ehuasso target within the broader 47km strike Zaranou shear zone."
High-Grade Gold Intersections
Assay results for primary 1m samples from previously reported 4m composites over the Ebilassokro target (refer RNS of
High-grade intersections at greater than 5-gram meters for the 1m primary air core ("AC") results received over the Ebilassokro target and 4m composite results in RC drilling at the Ehuasso target are reported in Table 1 below. All new intersections are reported in Table 1 and Appendix 1 at a 0.1g/t cut-off and maximum 1m of internal dilution for the 1m primary samples and 4m of internal dilution for the 4m composites.
All sampling was completed at the drill site and consisted of initial 4m composites submitted for analysis, of which all composites greater than 0.1g/t gold are re-submitted for analysis at 1m intervals from retained primary samples at the project site. ALS laboratory completed sample preparation in Côte d'Ivoire and sample analysis in
Ongoing drilling results continue to deliver high-grade drill intersections, with the highest-grade results received to date reported at the Ebilassokro target of 5m at 270.5g/t gold from 4m including 1m at 1,075g/t in hole ZAAC0321 within the 1m primary samples (refer Figure 1).
The high-grade results coincide with the previously reported 4m composite intersection of 16m at 1.02g/t gold from 4m, including 4m at 3.1g/t gold (refer RNS of
In addition to the high grades returned at the Ebilassokro target, noteworthy grades have been returned at the Ehuasso target in deep RC drilling. Hole ZARC0013 within the Ehuasso target area returned a high-grade intersection of 24m at 13.6g/t gold from 136m, including 4m at 76.2g/t gold for 4m composite samples in deep RC drilling (refer Figure 4).
The intersection occurs below previously reported intersections in hole ZARC0009, including 2m at 1.26g/t from 4m, 2m at 3.35g/t from 38m, 6m at 3.81g/t from 52m, 2m at 4.72g/t from 98m, 8m at 0.74g/t from 104m, 2m at 4.6g/t from 116m and 14m at 0.66g/t from 128m within the Ehuasso target (refer RNS of
The intersection is significant as it confirms high-grade mineralisation continuity at depth and extends mineralisation 125m below surface (refer Figure 5).
In addition to the high grades returned in hole ZARC0013, visible gold was observed in hole ZARC0019 within the Ehuasso main target at depth below previously reported AC drill intersection of 31m at 0.57g/t gold from 28m in hole ZAAC0284 (refer RNS of
Additional cross sections for reported drill results at Ehuasso are included in Appendix 2.
The second phase AC drilling programme has now been completed with 20,312m drilled in 404 holes across the Ehuasso and Ebilassokro targets. The RC drilling programme is progressing well with one rig active on the Ehuasso targets. Approximately 500m of RC drilling remains for completion of the second phase planned programme of 21,000m of drilling across both the Ehuasso and Ebilassokro targets, with additional results to be reported as soon as they become available and have been reviewed.
The Board is pleased with the progress that the Company has made in 2020 to date and looks forward to reporting through a busy upcoming period.
