Wainaleka is a copper-zinc volcanogenic massive sulphide (VMS) prospect situated in the central portion of SPL 1416. A diamond drilling program carried out by Australian Anglo American Ltd. (Anglo) in 1977 intersected highly anomalous values including1:

  • 6.2m @ 1.8% copper, 12.0 zinc and 25g/t silver (WLK-1A),
  • 10m @ 2.3% copper, 5.5% zinc and 47g/t silver (WLK-4),
  • 15.5m @ 1.5% copper, 1.3 % zinc and 8.0g/t silver (WLK-10)
  • The Anglo drilling results have shown the main mineralised zone is open at both ends and at depth2.

Recent (2007) exploration by previous operator Aljen Pacific Limited  included1:

  • Surface rock grab sampling along new forestry roads at the west end of the Wainaleka Deposit and 500m to the northwest returned 2.7% copper and 19.9% zinc and 7.1% copper and 14.4% zinc, respectively
  • Shallow vertical “backpack” diamond drilling intersection of 2.2m @ 1.9% copper, 11.8% zinc and 9 g/t silver from 2.2 to 4.8m at the west end of the Wainaleka Deposit3.

Recent geophysical interpretative work indicated that the prospective horizon extends over a strike length of 10 km.
