In a continuation of mineral exploration on a small licence centred ~100 km north of Olary, no new work was performed by licensee Alphadale over the three-year period July 2001 to July 2004. A new joint venture partner was sought to carry forward the...

Exploration for Kalkaroo or Portia style copper-gold deposits, and for Broken Hill type stratiform lead-zinc-silver deposits, both possibly formed within the Palaeoproterozoic basement intrusive rocks and high grade metasediments in an area lying...

Activity during Licence Year 5 was less than in the year before, mainly owing to BHP-Billiton having decided at the end of the Phase 1 drilling programme to withdraw its joint venture agreement funding from the Mutooroo and Thackaringa tenements,...

Regolith mapping over the Mingary 1:100 000 map area in the northeast of the State is in progress. To date, the Cockburn North, Cockburn South, Mutooroo North, Mutooroo South and Radium Hill South 1:25 000 maps have been completed. A well-developed...

The Mingary 1:100 000 map area in the north-east of the state covers part of the Curnamona Province. Five suites of basic intrusives have been identified in the area. The most widespread is a series of amphibole-bearing sills which, having an...

Gem-quality varieties of beryl occur rarely in South Australia and exist in insufficient quantities to be of current economic interest. Non-gem grade beryl, by contrast, is a widespread accessory mineral in many pegmatites of South Australia, but, at...

This report is Phase 1 of a management plan for the 'Radium Hill Mine Site and Low-Level Radioactive Waste Repository', and is essentially a preliminary investigation to establish a greater understanding of the characteristics of the site. Phase II...

The Proterozoic Curnamona Province extends across central eastern South Australia and into western New South Wales. Whilst most of the Province is obscured by younger sedimentary cover, regions of exposure are present in the northwest as the Mount...

This field guidebook provides brief geological summaries to sites in South Australia that were visited during the 2006 Broken Hill Exploration Initiative pre-conference excursion. Figures show the location of the field area and approximate location of...

Four areas on the south-western margin of the Palaeo-Mesoproterozoic Willyama Inliers were mapped in detail to elucidate the nature of their lithostratigraphy, structure and mineralisation. These basement inliers are composed of...

The excursion to the Old Boolcoomata region of the Olary Domain, Curnamona Province, in South Australia presents most of the stratigraphy of the late Palaeoproterozoic Willyama Supergroup and evidence for its complex deformation during the ~1600 Ma...

Current mapping on the Mingary 1:100 000 map area has been investigating the nature of the boundary between the Olary Domain and Broken Hill Domain, both of which are subdivisions of the Curnamona Province. Earlier work had settled on a prominent...

In May 2004 the Minister for the Department of Environment and Heritage purchased Bimbowrie Station pastoral lease. The station was purchased because it encompasses part of the Olary Ranges, which is part of the environmentally important Broken Hill...

The deformed metasediments of the South Australian Willyama Inliers (in the southern Curnamona geological province) preserve petrologic evidence of a complex and protracted metamorphic history. To assist with unravelling this history, there currently...

Approximately 30 square km of outcrop of Palaeoproterozoic basement rocks in the vicinity of Ameroo Hill were geologically mapped by the author at 1:10,000 scale, with the aim of identifying meso- and macroscopic rock structures and lithologically...

This report book contains SHRIMP zircon U-Pb geochronological data obtained in May 2010 from the Curnamona Province, for three igneous rock samples derived from the Benagerie Ridge region and one metasedimentary rock sample taken from the Mingary...

Former sheep station ‘Bimbowrie’, situated in the Olary Ranges, South Australia, was purchased by the South Australian Government as a conservation park in 2004. It has had a long history of mining, mineral exploration and geoscientific investigation....

The Curnamona Province is the southern remnant of the Palaeoproterozoic Pb-Zn belt, and represents but a small fragment of the original superbasin. Geological data supports the idea of the basin being a rift, with sediments in the Broken Hill Domain...

This short field trip was designed to provide an overview of rocks of different ages in the greater Broken Hill area, as part of the Uncover Curnamona technical sessions held at the Broken Hill Resources Symposium 2015. It was run on Thursday 28 May...
