Kaoko Metals (ASX:KAO) has intersected broad zones of visual copper mineralisation in its first drilling at the Chalkos Copper-Silver Project in Namibia.
The company completed two diamond holes at the Otniel Prospect, with DDOT002 returning 60.25m of visible copper mineralisation from 36.65m, including 32.36m of strong visible mineralisation from 59.30m.
DDOT001 intersected 51.83m of visible copper mineralisation from 39.27m, including 17.20m of strong visible mineralisation from 58.37m.
Visual logging identified numerous copper minerals including chalcocite, cuprite, malachite, native copper, dioptase, and chalcopyrite across multiple lithological units.
Managing Director Gerard O’Donovan says the company is pleased to have observed broad zones of copper mineralisation in the first two holes at Otniel.
“DDOT002 intersected over 60m of predominantly malachite-chalcocite mineralisation, including a 32m zone of strong visible mineralisation, while DDOT001 returned over 51m of visible mineralisation including 17m of strong visible mineralisation,” O’Donovan says.
DDOT002 contains the ‘strongest’ visual copper mineralised interval, with chalcocite and malachite estimates 5–8%, and an interval containing approximately 4% native copper from 86.40m to 91.66m.
Meanwhile, DDOT001 demonstrates visible copper mineralisation across a vertical extent of over 120m.
Both holes record zones of mylonitisation coincident with the ‘strongest’ visible copper mineralisation, indicating structural deformation has played a significant role in focusing mineralisation.
Drilling continues at Otniel to follow up on the initial intersections before the rig moves to test the Donkey Hill target. Assays are expected in four to six weeks.
The 800km2 Chalkos Project is located within the Kaoko Copper Belt and is considered analogous to stratiform sediments that host Central African Copperbelt deposits.
Kaoko Metals holds 100% ownership of the project through two exclusive prospecting licences.
