Mako Gold Limited (ASX:MKG) has achieved multiple high-grade hits at shallow depths in its ongoing 10,000m reverse circulation (RC) and diamond drilling (DD) programme on the Tchaga Prospect at the company’s Napié Project in Côte d’Ivoire.
Assay results of 13m at 20.82g/t Au from 32m; 9m at 29.45g/t Au and multiple high-grade single metre assays up to 102.5g/t Au have confirmed the company’s confidence in the area’s prospectivity.
Managing Director, Peter Ledwidge, said the Tchaga Prospect is associated with a +40ppb gold soil anomaly coincident with a +30km-long shear zone, thought to be a major control for gold mineralisation.
“We are very encouraged by our latest drilling results that demonstrate thick and high-grade gold mineralisation within 50 vertical metres of surface and open in multiple directions.
This is consistent with our strategy to define significant shallow gold mineralisation within our +30km corridor. The reported 13m at 20.82g/t Au is not the result of a single high-grade assay with lesser assays spread out over the reported interval, but rather a combination of one metre assays which include 102.5g/t Au, 60.51g/t Au, 39.31g/t Au and 24.23g/t Au.
“Although most of the mineralisation intersected in drilling to date seems to be associated with the north-south trending shears, it appears that the high-grade encountered in NARC145 is associated with the intersection of one of the many southwest-northeast trending cross structures which may represent dilational zones.
“It is common to intersect high-grade shoots in these secondary dilational structures. This has provided us with greater geological insight within our project area and allowed us to define a range of new drill targets.
“We will be targeting more of these dilational zones in future drilling while also testing along the north-south structures.”
Assay results have been received for an additional five RC drill holes of the planned 90-hole drill programme which is scheduled to run through to December 2020.
The drilling results continue to build a solid story at Napié. The Induced Polarisation (IP) geophysical survey is proving to be an extremely useful tool for delineating the overall north-south orientation of the mineralised zones
