Proposed and possible airborne electromagnetic surveys are listed below in order of level of scoping to date (note: not all surveys will be funded in the OESP; prioritisation is yet to be finalised).

Paterson Province, WA (acquisition commenced September 2007)

Target mineral systems:	Unconformity-related U
Example:	Kintyre U deposit
Geology:	Graphitic units in Rudall Complex basement Overlying Coolbro Sandstone Major structures facilitating fluid flow Proximity to Archaean (Pilbara) granite in northwest of survey area
Comments:	Survey excludes Rudall River National Park

Frome Embayment, SA (proposed; scoping well advanced)

Target mineral systems:	Palaeochannel U, Sandstone U
Example:	Beverley, 4 Mile, Honeymoon
Geology:	Namba Formation (Cz), Eyre Formation (Cz) Eromanga Basin (K) U-rich Mesoproterozoic granite
Comments:	Brownfields – AEM to provide regional context to outline palaeochannels and K-Cz faulting

Pine Creek, NT (proposed; scoping well advanced)

Target mineral systems:	Unconformity-related U
Example:	Ranger, Jabiluka
Geology:	Archaean granitic domes Graphitic units in Palaeoproterozoic rocks Overlying Kombolgie Sandstone
Comments:	Aim to map thickness of Kombolgie Fm as well as identify graphitic schists in basement; brownfields

Birrindudu/Tanami, NT (possible; proposal being scoped)

Target mineral systems:	Unconformity-related U
Geology:	Archaean - Proterozoic granite in domes Carbonaceous units in Tanami Group basement Overlying sandstone units in Birrindudu Group
Comments:	Greenfields, but known minor U prospects

[back to top]

Northern Eyre peninsula, SA (possible; proposal being scoped)

Target mineral systems:	Unconformity-related U
Geology:	Mesoproterozoic Hiltaba Suite granites Carbonaceous units in the Hutchison Group Overlying Pandurra Formation, Corunna Conglomerate and Blue Range Beds
Comments:	Greenfields but some minor U prospects known

[back to top]

Capricorn Orogen / Northern Yilgarn margin, WA (proposal being scoped)

Target mineral systems:	Unconformity-related U
Geology:	Abundant U-rich, low Ca, Archaean granite Adjacent-overlying Palaeoproterozoic sediments (Yerrida and Earaheedy Basins ) Major structures in the Archaean basement
Comments:	Greenfields project but has several of key ingredients of unconformity-related U

[back to top]

Westmoreland, Qld (proposal being scoped)

Target mineral systems:	Mafic intrusive-related U/unconformity-related U
Geology:	Murphy Tectonic Ridge/Cliffdale Volcanics (source of U?) Overlying Westmoreland Conglomerate
Comments:	Brownfields – numerous small U deposits

[back to top]

Mount Isa– eastern margin, Qld (proposal being scoped)

Target mineral systems:	Sandstone U - Cainozoic palaeochannels
Geology:	High-U Mesoproterozoic Williams Batholith granites
Comments:	Greenfields region but numerous generally small U deposits in Mt Isa Inlier

[back to top]

Ngalia – Amadeus Basin region, NT (proposal being scoped)

Target mineral systems:	Cainozoic palaeochannels
Geology:	U-rich granite in Arunta Complex Poorly known palaeochannels with >200 m of fill and some evidence of lignite
Comments:	Greenfields region

[back to top]

Southern Yilgarn margin, WA (proposal being scoped)

Target mineral systems:	Palaeochannel U
Example:	Mulga Rock
Geology:	Abundant U-rich, low Ca, Archaean granite to north/northwest Palaeochannels containing lignite which has fixed U
