Highlights:

  • First line of drilling identifies shallow and wide intervals of cobalt and nickel mineralisation including:
    • 20 metres at 1% cobalt and 0.7% nickel from 32 metres including
      • 11 metres at 13% cobalt and 0.63% nickel from 41 metres
    • 16 metres at 12% cobalt and 0.52% nickel from 40 metres including
      • 12 metres at 13% cobalt and 0.55% nickel
    • Cobalt mineralisation is 400 metres wide and 16-20 metres thick
    • Further six lines of drilling completed – assay results pending
    • Drilling contract for Coronation Dam cobalt-nickel project finalised- to commence in May

White Cliff Minerals Limited (“White Cliff” or the “Company”) is pleased to provide an update on exploration drilling conducted at its 100%-owned Coglia Well cobalt-nickel project near Laverton in the Western Australian goldfields.

The Company has completed 2,869 metres of air core drilling at Coglia Well, with the aim of verifying historical drill results and testing the scale and extents of cobalt and nickel mineralisation. Assay results have been received for the first two of the seven lines of drilling. Significant cobalt-nickel mineralisation has been identified in four consecutive holes extending across a width of 400 metres (section line 9,787,300 North), with assay results including:

CGAC006:      16 metres at 0.12% cobalt and 0.52% nickel from 40 metres depth including:

12 metres at 0.13% cobalt and 0.55% nickel (ended in mineralisation)

CGAC005:      20 metres at 0.1% cobalt and 0.7% nickel from 32 metres depth including:

11 metres at 0.13% cobalt and 0.63% nickel (ended in mineralisation)

CGAC016:      16 metres at 0.06% cobalt and 0.51% nickel from 34 metres

CGAC017:      13 metres at 0.04% cobalt and 0.78% nickel from 38 metres (ended in mineralisation)

Cobalt mineralisation occurs as a flat sub-horizontal layer in the regolith profile slightly above and overlapping with nickel mineralisation approximately 16-20 metres thick and 30-60 metres below the surface. Higher grade cobalt mineralisation identified in previous drilling also occurs on the same northing further east in MERC004 which intersected 28 metres at 0.12% cobalt and 0.65% nickel for 60 metres. Drilling adjacent to this hole failed to penetrate the base of the paleo-channel but there is potential for this mineralised zone to be up to 300 metres wide. Due to difficult ground conditions further drilling programs will be conducted with a more powerful RC rig.

White Cliff Managing Director Todd Hibberd said: “The Company is very pleased with the initial assay results from Coglia Well, which confirm the high grade of the cobalt mineralisation on this section line. We expect further assay results in the coming weeks to confirm the grade and scale of the cobalt and nickel mineralisation identified in previous drilling. The Company will then commence metallurgical test work to evaluate processing methods and economics.”

“RC Drilling will shortly commence at the Coronation Dam cobalt-nickel project to evaluate the zones of high-grade cobalt mineralisation identified in previous drilling.”

Further updates will be provided as this process continues.
