Napperby Project Australia

Favourable geology in right location with logistic support

  • Pine Creek Pegmatite province hosts Core Lithium’s Finniss project (ASX:CXO, market Cap AUD1.0 billion) with the NT’s first ever granted mining lease for lithium
  • The Northern Arunta Pegmatite is the second province and is expecting a lithium discovery
  • Napperby Li project is in the west of Northern Arunta pegmatite province with over 1160km2 tenement package, 100% owned.
  • Easy access via Stuart Highway and Tanami highway, close to Central Australian Railway with access to Darwin Port

LCT pegmatite identified with historical Sn and Ta production

  • Multi pegmatite dykes with tin (Sn) and Tantalum (Ta) mineral occurrence identified
  • Work by the Northern Territory Geological Survey reported in 2005 confirmed that the pegmatites in the area were of the LCT (lithium-caesium-tantalum) type

Significant Uranium potential identified

  • Oceana’s Napperby Project covers some of Arunta Province’s hottest granites plutons, the Wangala Granite (uranium) and Ennugan Mountains Granite (uranium/thorium)    
  • Both granite plutons show outstanding uranium/thorium ratios and are almost fully encapsulated within Napperby’s EL32836 and ELA32841
  • Follow-up exploration activities will target uranium and Rare Earth Elements (REEs) in parallel with Lithium-Caesium-Tantalum (LCT) pegmatites

Significant land holding with LCT pegmatite identified

  • Five mineral localities (U, Ta, W, Cu and apatite) are recorded by the NTGS, three of which are associated with pegmatites
  • Ta-Sn mineral occurrences were documented.
  • Field inspection completed confirming pegmatite outcropping
  • Historical uranium exploration highlight the magma sources of the region is fertile for Li-Cs-Ta pegmatite
  • Nine mineral localities (U, Ta, W, Cu and apatite) are recorded by the NTGS, three of which are associated with LCT (Lithium-Cesium-Tantalum) pegmatites
  • Rock chip XRF analysis returned 35.4% Ta and 18.5% Sn, however Li was not assayed
  • Ta-Sn historical production
  • Remote sensing imagery interpretation on pegmatite outcrop completed, waiting for field inspection
  • Five mineral localities (U, Ta, W, Cu and apatite) are recorded by the NTGS, three of which are associated with pegmatites
  • Ta-Sn mineral occurrences were documented.
  • Field inspection completed confirming pegmatite outcropping
  • Historical uranium exploration highlight the magma sources of the region is fertile for Li-Cs-Ta pegmatite
