READ: White Cliff Minerals prepares for 3,000 metres of drilling at Coglia Well cobalt nickel project
Statutory approvals were recently received for an initial 3,000-metre drilling program at its Coglia Well cobalt and nickel project in Western Australia.
Drilling undertaken at the prospect in 2016 identified widespread cobalt and nickel mineralisation over an area 2,500 metres in length and 500 metres in width.
Some of the better intersections included 28 metres at 0.12% cobalt and 0.55% nickel from 60 metres and 12 metres at 2.18% nickel and 0.06% cobalt.
Coglia Well is in highly prospective territory 70 kilometres southeast of Laverton in the Northeast Goldfields.
Further drilling approvals sought
Drilling approvals are also being sought for the Coronation Dam and Ghan Well cobalt nickel projects.
White Cliff is planning air-core and RC programs for these projects with 3D geological and orebody models are being generated.
