A large-scale, significantly underexplored lithium opportunity in 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 is the second province and has potential for the next significant 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 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 granite 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.
