The R502 series of maps has been replaced by the National Topographic Map Series (NTMS). The R502 series consists of 542 map sheets and covers Australia at a scale of 1:250,000. It was compiled from aerial photography, but only about one quarter of the series was contoured. The standard sheet size is 1 degree of latitude by 1.5 degrees of longitude. Transverse Mercator map projection and Clark 1858 datum were used. Coverage of the country was completed in 1968.

The Corporate Administrative Records Collection of Geoscience Australia (GA) is a bi fold collection; consisting of electronic/digital documents and records in physical paper format. The digital collection consists of electronic information, which may be "born digital" (created using computer technology) or converted into digital form from their original format (e.g. scans of paper documents). These records are created by all GA employees and are evidence of business conducted by GA and its predecessors. The location of these digital records is in TRIM (electronic document management system). This product treats documents and records in the same way, so that end users perform the same task on all items that are stored in the system, irrespective of whether the item is a document or is to be declared as a record. The digital records can be captured in any format; e.g. excel document, word document, pdf document, emails, etc. When a user saves a document for the first time in TRIM they are prompted for metadata, which is then used to create the record.

Mineral deposits are a product of the coincidence of favourable geological conditions within a given spatial and temporal setting. Collectively, these key geological elements may be considered as aspects of a mineral system. Mineral system-based investigations of the potential for a range of uranium systems have recently been undertaken in northern Queensland, east-central South Australia and the southern Northern Territory. Building on the methodology employed in northern Queensland, the mineral system assessment in South Australia and the Northern Territory consists of four key system components: (1) sources of metals and fluids, (2) drivers of fluid flow, (3) fluid pathways and architecture, and (4) depositional sites and mechanisms. Favourable geological criteria are developed from these four components, which are in turn translated into mappable geological proxies. Thus, the mineral systems framework drives the collection and synthesis of geoscientific data. This approach minimises the influence of localised geological controls, which may only be significant at the mine scale, and allows the system to be mapped on a broad scale, maximising the 'footprint' of mineralisation. Locations of known mineralisation are not considered in the assessment but are used to verify results. By employing a systems-based approach, the potential of relatively unexplored areas may be assessed objectively, transparently and systematically. Significantly, the approach used here is able to predict the potential for unrecognised mineralisation beneath cover. The assessments undertaken for uranium potential successfully reproduce the location of known uranium deposits and, importantly, delineate several areas where uranium mineralisation is currently unknown.
