The Broken Hill Exploration Initiative (BHEI) is a collaborative
venture between the Australian Geological Survey Organisation
(AGSO), Mines and Energy South Australia (MESA) and the
New South Wales Department of Mineral Resources (NSWDMR)
to provide a new generation of geoscientific information to
promote and enhance the exploration for, and discovery of, new
deposits in the Broken Hill region. The area under investigation
(Figure 1) exceeds 150 000 square kilometres on either side of
the NSW-SA border and is centred on the city of Broken Hill. N.T.

investigation by the Broken HiII Exploration Initiauvr highlighted on the map of Australia. A major impediment to the exploration for, and to the
understanding of, the genesis of the world-class Broken Hill
Pb-Ag-Zn deposit is the structural and metamorphic complexit
of the region. Important objectives of the BHEI are therefore: I. the definition of the three-dimensional structure of the
province, 2. the deformation history, and 3. the stratigraphic and age relationships of the rock units.
Early discussions between the BHEI partners and industry
scientists revealed that new geophysical surveys would be a key
requirement to help advance the understanding of the province,
especially a contiguous high resolution airborne geophysical
dataset covering both outcrop and areas of shallow surficial cover.
The purpose of this paper is to draw attention to the new high
resolution airborne geophysical data and to discuss their
interpretation and potential for enhancing the knowledge of the
Willyama Supergroup geology.
