The North Australia Project (NAP) was initiated in July 2000 following negotiations between the Northern Territory Geological Survey (NTGS) and the Australian Geological Survey Organisation (now Geoscience Australia). The NAP was a joint project undertaking geoscientific studies in the Tanami, Arunta and Tennant regions of central Australia to help encourage mineral exploration. The project continued until June 2004, when the Geological Survey of Western Australia (GSWA) began regional data acquisition in the western Tanami region. In July 2004, the Tanami Project, a joint initiative between Geoscience Australia, NTGS, and GSWA to increase mineral exploration replaced the NAP. Although NTGS and GSWA have continued interests in the Tanami and Arunta regions, the collaborative Tanami Project will finish in December 2006. The purpose of this product is to provide reports and datasets summarising the results of the project at this time. The only major products not included in this DVD are the results of the Tanami seismic survey and modifications to the on-line 3D models required by the seismic results. These will be released separately, beginning in August 2006. As this report is intended to be as up-to-date as possible, it refers to a number of manuscripts that are either in press or in preparation. Although these manuscripts cannot be provided here, much of the data upon which the conclusions are based are presented in summary, either in abstracts, presentations, or data tables.

In September 2002 a medium resolution seismic reflection survey was undertaken at the St Ives gold field, Western Australia. Trace Energy Services was contracted by the Australian National Seismic Imaging Resource (ANSIR) to conduct the St Ives Victory Survey. The survey uses two Hemi60 vibrators and an ARAM24 acquisition system. The data were processed, and correlated with drillhole geology and drillhole geophysics to facilitate interpretation. The seismic sections demonstrate that seismic reflection is effective at imaging stratigraphy and structure in Archaean terrains, even at relatively shallow depths (less than 500m). A package of strong reflections is associated with the mafic stratigraphy at St Ives. Raw data for this survey are available on request from clientservices@ga.gov.au

The project initially focused on the St. Ives gold camp with additional studies on the Golden Mile and selected areas in the Kalgoorlie-Kambalda corridor. Additional resources were provided by St. Ives Gold Company Pty Ltd and Placer Dome to support researchers on-site at St. Ives, Kanowna Belle and Wallaby. These resources are managed through MERIWA project M358 and selected results of this project, as well as information from the pmd *CRC Y2 project, are integrated into the Final Report.

This report is a synopsis of research compiled and carried out within the Predictive Mineral Discovery CRC F3 project "Micrometallogeny of hydrothermal fluids". The F3 project's original objectives were: (1) Geology-driven terrain and ore fluids investigations to evaluate the chemistry and fluid processes within mineral systems in order to extend the focus of fluid studies beyond direct ore deposit analysis. (2) LAICPMS and PIXE technique and methodology development were techniques utilized throughout the project and methodologies were developed for their combined application. (3) Diamond-cell autoclave experiments component of the project was a scoping-collaboration in year one of F3 with the Museum of South Australia. (4) Database development and fusion with numerical modelling resulted in development of a web-based database for fluid inclusion research has been successful and is currently accessed at http://www.ga.gov.au/minerals/research/methodology/geofluids/flincs_about.jsp

Deep-seismic reflection data across the Eastern Goldfields Province, northeastern Yilgarn Craton, Western Australia have provided information on the regions crustal architecture and on several of its highly mineralised regions. The 2001 Northeastern Yilgarn Deep Seismic Rflection Survey data has imaged several prominent crustal scaled features, including an eastward thickening of the crust across the northeastern Yilgarn Craton, the subdivision of the crust into three broad layers, the presence of a prominent east dip to the majority of the reflections and the interpretation of three east-dipping crustal-penetrating shear zones. These three east-dipping shear zones are major structures that subdivide the region into four terranes. Raw data for this survey are available on request from clientservices@ga.gov.au

This project was set up to demonstrate how geochemistry is able add-value to exploration. The project has produced improved total system ore genesis models, a comprehensive up-to-date database and associated software tools for hydrothermal geochemistry modelling.

Architecture A1 Project -What are the fundamental characteristics of mineralised (trans-lithospheric) fault systems? The principal aim of the project has been to understand why some faults systems are mineralised and why others are barren, and whether a mantle component is essential to form major ore deposits. The objective of the study has been to determine, and rank, a set of critical parameters that could be applied to identify favourable conduits for ore-forming fluids and whether these fault systems are likely to be metallogenically well-endowed with respect to precious and base metal mineralisation.

The principal objective of the H4 Project was to evaluate existing techniques and develop new enabling technologies in geochronology and isotope geoscience to significantly improve our ability to constrain the timing of ore formation and, therefore, expand predictive capabilities. A fundamental goal was the evaluation of existing dating methods and interpretations, particularly with respect to gold deposits in low grade terrains, and to investigate potential new dating methods such as 40Ar/39Ar laser probe analyses of mica-bearing pyrite linked to gold mineralisation. A second major goal of the H4 project was to initiate development of halogen/noble gas geochemistry technology and expertise within the pmd *CRC to enable this unique geochemical method to be applied to ore deposits in the flagship terrains in the second stage programme of pmd *CRC.

The Uranium Systems Project is a key part of the $59m Onshore Energy Security Program (OESP) underway at Geoscience Australia (2006-2011). The project has three objectives: (1) develop new understandings of processes and factors that control where and how uranium mineralisation formed, (2) map the distribution of known uranium enrichments and related rocks in Australia, and (3) assess the potential for undiscovered uranium deposits at regional to national scales. Objective (1) has been addressed initially by reviewing current classification schemes for uranium deposits. Most schemes emphasise differences in host rock type and list 15 or more deposit types. An alternative scheme is proposed that links the apparently separate deposit types in a continuum of possible deposit styles. Three end-member uranium mineral systems are: magmatic-, basin-, and metamorphic/metasomatic-related. Most recognised deposit styles can be considered as variants or hybrids of these three end-members. For example, sandstone hosted, unconformity-related and "Westmoreland" style deposits are viewed as members of basin-related uranium systems and which share a number of ore-forming processes. Identification of the spatial controls on uranium mineralisation is being investigated using numerical modelling, with the Frome Embayment of SA as a first case study. Mapping the distribution of uranium in objective (2) has commenced with the release of a new map of Australia showing the uranium contents of mainly outcropping igneous rocks, based on compilation of whole rock geochemical data. A clearer picture of uranium enrichments is also emerging through cataloguing of an additional >300 uranium occurrences in the MINLOC mineral occurrence database. Finally, the recently completed Australia-wide radiometric tie-line survey is providing a new continent-scale view of uranium, thorium and potassium distributions in surface materials. To assess potential for undiscovered uranium deposits, new OESP data in targeted regions of Australia are awaited, such as airborne EM, seismic and geochronology data.
