Australian Mineral Exploration - A Review of Exploration for the Year 2005

Australian mineral exploration spending in 2004-05 rose by 31% to $1028.3 million of which 39.3% was spent on the search for new deposits. 
Total global non-ferrous mineral exploration budgets rose 38% to an estimated US$5.1 billion in 2005. 
Western Australia received 59% of Australian mineral exploration spending in 2004-05 as spending rose in all States except Victoria. 
Gold remained the main target but its share of spending was eroded by increased spending on nickel, copper, iron ore, coal and uranium. 
Exploration resulted in significant increases in resources at known deposits and a substantial number of drill intersections of economic interest, the most notable being the discoveries of copper-gold mineralisation at Carrapateena (Gawler Craton), mineral sand in the Eucla Basin, and gold at the Trident deposit (Yilgarn Craton).

AUSGeoid98 v.1.0 data files:  (sc49-07)

AUSGeoid98 data files contain a 2 minute grid of AUSGeoid98 data covering the Australian region, which you can use to interpolate geoid-ellipsoid separations for the positions required.You can use your own interpolation software, or you can use Geoscience Australia's Windows Interpolation software (Winter). The data files are text files in a standard format that cover the same area as standard topographic map areas. Files covering both 1:250,000 (approximately 100 x 150 km) and 1:1,000,000 (approximately 400 x 600 km) map areas are available. There is a 4 minute overlap on all sides of each area. Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places. AUSGeoid98 deflections of the vertical were computed from the geoid-ellipsoid separation surface, while the AUSGeoid93 deflections of the vertical were computed from OSU91A.

Connemara 1:250 000, R502 historical topographic map

The R502 series of maps has been replaced by the National Topographic Map Series (NTMS).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.

NTData (digital geology of the Northern Territory), Truant Island

These data are a digital representation of information depicted on printed maps from the Australia 1:250 000 Geological Series produced by AGSO and the Northern Territory Geological Survey (NTGS) between 1963 and 1998.  The data are in a tiled format 
and are not seamless, although basic edgematching has been done where possible.  Tiles are arranged according to the standard Australian 1:250 000 sheet breakup.  The complete dataset is comprised of the 90 tiles covering the Northern Territory.

Gravity Survey (P197467), gravity point data

Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
 This Gravity Survey (P197467) contains a total of 72 point data values acquired at a spacing of 350 metres. The data is located in SA and were acquired in 1974, under project No. 197467 for None.

GSWA Esperance Doserate Grid Geodetic

The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of potassium (K), uranium (U) and thorium (Th). The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose. The terrestrial dose rate grid is derived as a linear combination of the filtered K, U and Th grids. A low pass filter is applied to this grid to generate the filtered terrestrial dose rate grid.
This GSWA Esperance Doserate Grid Geodetic has a cell size of 0.00083 degrees (approximately 85m) and shows the terrestrial dose rate of the Esperance - Malcolm, WA, 2008. The data used to produce this grid was acquired in 2008 by the WA Government, and consisted of 84609 line-kilometres of data at 400m line spacing and 60m terrain clearance.

Geography - Physiography - Elevation

Elevation data is a point, line or surface geographically located in the x and y relative to a horizontal datum, that includes a height (z) above or below a known vertical datum. Bathymetry will deal with all offshore elevation data.
- Elevation data will include both raw elevation data and digital elevation models (DEM); 
- Spot Heights, points on the earth's surface, of known elevation.
- Contours, lines which represents an imaginary line on the ground joining points of equal elevation.
- Horizontal Control Points, points on the ground, the horizontal position of which has been determined by geodetic survey.
- Digital Elevation Models (DEM) are interpolated representations of a surface. Elevation points are spaced at a regular interval so as to create a grid or lattice. These grids can be directly observed or, more generally, they are computed from more than one of the above mentioned irregular spaced  elevations.
- Digital Terrain Models (DTM) are bare earth DEM's representing the terrain They are interpolated using a combination of elevation information and could also be constrained using break lines, such are cliffs, drainage, coast etc.
- Digital Surface Models (DSM) are also DEM's, but they include non-surface objects like trees, buildings etc. So, a DSM = DTM + all non surface objects.
- Triangulated Irregular Network (TIN). A vector data structure that partitions geographic space into contiguous, nonoverlapping triangles. The vertices of each triangle are sample data points
with x, y, and z values. These sample points are connected by lines to form Delaunay triangles.
TINs are used to store and display elevation models.
- Hydrologically enforced Digital Elevation Models (HDEM) represents DEM with drainage enforcement.
The quality of a DEM is a measure of how accurate elevation is at each pixel (absolute accuracy) and how accurately the morphology is represented (relative accuracy). Several factors affect the quality of DEM-derived products: terrain roughness, sampling density (elevation data collection method), grid resolution or pixel size, interpolation algorithm, vertical resolution and terrain analysis algorithm.

Widgiemooltha South, WA, 2012 (P1256), elevation line data

The Digital Elevation Model represents ground surface topography between points of known elevation. The elevation data was calculated using the altimeters and Global Positioning System (GPS) sensor used for the benefit of airborne magnetic and radiometric data on the same survey. The elevation is the height relative to the Australian Height Datum GDA94 (AUSGEOID09). The processed elevation data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
 These line dataset from the Widgiemooltha South, WA, 2012 survey were acquired in 2012 by the WA Government, and consisted of 131391 line-kilometres of data at 100m line spacing and 50m terrain clearance.
