JOHANNESBURG (miningweekly.com) – All trenches at mineral exploration company Kodal’s 345 km2 Nangalasso project, in Mali, have returned anomalous gold values that confirm the surface gold anomalism previously defined at the project.
The assay results returned a maximum value of 3 m at 0.37 g/t gold from its NNTR009 trench.
Five trenches were completed for a total of 264 m with a total of 88 composite trench samples, six rock chip samples and quality assurance and quality control samples. A total of 103 samples were also dispatched to SGS Laboratories in Bamako, Mali.
Trench NNTR005 contained zones of anomalism associated with veining and alteration with intersections including 3 m at 0.27 g/t gold and 6 m at 0.12 g/t gold. This trench is located along strike from previous drill intersections and previous trenching that returned significant mineralisation.
The trench positions were located to target areas of active artisanal mining and follow-up defined structural trends to improve the targeting of the proposed aircore drilling programme.
Rock chip sampling also returned anomalous results with a best result of 0.23 g/t gold associated with a brecciated quartz vein within altered metasedimentary units.
“These results confirm the surface gold anomalism at Nangalasso. The trench samples have highlighted extensive zones of alteration and structural shearing that is an important target for drill testing at depth.
“The trench sampling has confirmed broad anomalous zones, with up to 45 m in width of anomalous values returned. The next steps will be to perform further field geological mapping and sampling to define the zones of alteration and structural complexity prior to undertaking further aircore drilling,” said Kodal CEO Bernard Aylward.
The next phase of exploration at Nangalasso is a programme of field mapping and targeting of the extensions of the defined gold anomalous zones followed by a programme of aircore drilling, aimed at testing the depth potential of the gold anomalies beneath the surface affects.
