Executive Summary This report describes drill hole data collected in support of the Paterson Province (Paterson) airborne electromagnetic (AEM) regional survey flown between 10th September 2007 and 28th October 2008. The survey was flown by Fugro Airborne Services on behalf of Geoscience Australia as part of the Onshore Energy Security Program of the Australian Government. Over 6,500 drill hole locations were collected from public domain exploration and mining company reports, together with generalised or detailed geological logs, down hole surveying information and rock codes used to describe the lithostratigraphy of the Paterson region. Over 4,300 geological logs have been entered into the database. A priori information available such as this drill hole database provide direct observations of the sub-surface. This information is necessary to map geological features interpreted from the AEM fast approximate inversion and layered earth inversion results with increased certainty. Other interpretation products also benefit from this constraint.


1 Introduction This report summarises a database of publicly-available drill hole data collected for the Paterson Province (Paterson) regional airborne electromagnetic (AEM) survey interpretation program (Costelloe et al. 2007; Sorensen et al. 2009; Whitaker 2009; Roach in prep). The Paterson AEM survey was conducted as part of Geoscience Australia’s Onshore Energy Security Program (OESP) funded by the Government of Australia (Johnson 2006; 2007; Johnson & Stolz 2009; Stolz 2009). Fugro Airborne Surveys Pty. Ltd., for Geoscience Australia, undertook a TEMPEST AEM and magnetic survey between the 10th of September 2007 and the 28th of October 2008 over the Paterson area in Western Australia. The survey was flown over two large blocks: North Paterson; and South Paterson (Figure 1), in 1, 2 and 6 km line spacings. Drill hole data described here cover both areas. The data acquisition and interpretation program are described further in Roach (in prep.)

2 Purpose Conductivity distributions derived from AEM data, in particular layered earth inversions (LEI), should be integrated with all other a priori information such as surface observations, 3D geological models, other geophysical datasets and drill hole data (Lane et al., 2000). To this end the interpretation of AEM data benefits from the collection and interpretation of reliable 2- and 3-dimensional geological and geophysical data. A drill hole data collection exercise commenced in August 2008 and was essentially completed by July 2009, although small amounts of data were entered periodically as they became available after this date until publication. The information contained within the drill hole database was used, together with other geological and geophysical data, to help interpret the AEM fast approximate inversion data products delivered by the contractor and the layered earth inversion products produced by the AEM Group at Geoscience Australia.

3 Data sources and reliability 3.1 DATA SOURCES Drill hole location and geological data in this database are derived primarily from digital and non-digital reports lodged in the Geological Survey of Western Australia’s (GSWA) WAMEX database, but also some drill hole location data from the GSWA’s EXACT database. Both are available on-line at the Government of Western Australia’s Department of Mines and Petroleum website at http://www.dmp.wa.gov.au/. The WAMEX database delivers digitised reports and maps in Adobe PDF format using Digital PaperTM technology. The WAMEX database can be searched by location, item or report number, commodity type or keyword. The EXACT database contains drill hole collar locations and information relating to the exploration activity, exploration company and corresponding WAMEX database report number. At the commencement of the data collection process, the EXACT database was poorly populated, hence the drill hole database described here was constructed primarily from drill hole information taken from digitised reports from the WAMEX database, located using geographical area searches. The bulk of drill hole information is available on-line, however a number of reports were not available in digital form at the time of writing and must be viewed in their original paper forms at the GSWA offices in Perth, WA. A table describing the WAMEX report number, WAMEX item number and digital or non-digital status of individual reports is included in the Appendix. 3.2 DATA LOCATION RELIABILITY Drill hole location data described in this collation have varying positional accuracy, depending on the age of the data and the quality of surveying used to originally locate them. Pre-1980s hole locations are estimated to vary by as much as 1 km. The positional accuracy of each hole in post-1980s surveys is estimated as a radius of 200 m around each point, but later surveys using Global Positioning System satellite navigation are estimated to lie within a 100-50 m radius.

3


Pre-1980 company reports may quote drill hole locations derived by surveying or from early 1:250,000 topographic maps of the region; these locations are often quoted using latitude and longitude to the nearest minute. Thankfully there are very few holes located using this method and these are chiefly located in the northwest of the area around the Oakover River and Bamboo Creek. Most drill holes in the database were located using surveying and increasingly by satellite techniques since the mid-1980s. The bulk of recent (pos-1980) drill hole locations are included in company reports as tables of easting-northing pairs, so these coordinates have simply been transcribed and converted to the latest datum. Some reports contain only maps showing drill hole locations; these were converted to raster images and georeferenced using MapInfo or ArcGIS software to allow the drill hole locations to be digitised provided the maps contained some kind of easting-northing or geographic grid. A small number of maps were printed and drill hole locations were calculated by hand based on easting-northing or geographic grids. Data in the EXACT database were found to be generally reliable in terms of geographical location, however, care must be taken because some points are obviously out of place when examined. For example, some clusters of drill holes plotting in the Paterson region actually describe holes drilled in the Laverton or Kalgoorlie regions, nearly 1000 km further south. These errors are assumed to be stem from errors in the initial data entry. 3.3 DATUM AND PROJECTION Drill hole coordinates in the drill hole collars file (Paterson_collar.csv) are quoted as Universal Transverse Mercator (UTM) coordinates in the Map Grid of Australia 1994 (MGA94) using the Geodetic Datum of Australia 1994 (GDA94). Drill hole locations quoted in company reports have been recalculated using Redfearn’s formula to convert geographic to grid and/or a block shift method described in detail on the Geoscience Australia website at http://www.ga.gov.au/ geodesy/datums/calcs.jsp. A variety of datums and projections have been used to describe drill hole locations in the company reports (Table 1) and they often lag several years behind official standards. In many instances the datum and projection are not quoted; in these cases the drill hole locations have been assumed to use the datum and projection quoted in Table 1 according to the year of publication. A minority of drill hole locations have been quoted using tape-and-compass survey grids which bear little relation to real-world coordinates. Where no other information exists regarding the location of these grids, the data have been discarded. Fortunately, most of the company reports contain a pair of coordinates with survey grid-to-UTM conversions, survey baseline parameters or a geographic or UTM grid that can be converted into real-world coordinates, so the locations of drill holes may be calculated. Table 1: Assumed datums and projections used to locate drill hole data in this collation.

There is an approximately 200 m shift to the northeast between coordinates based on older datums (Clarke 1866, AGD66 and AGD84) and newer datums (WGS84 and GDA94). Transformations between the different systems are available on the Geoscience Australia website (http://www.ga.gov.au/) at varying levels of accuracy. 3.3 GEOLOGICAL RELIABILITY The quality of descriptions of drilled geological materials varies widely over the range of reports in the database, from “sand” to detailed facies descriptions and lithostratigraphic unit names. Therefore some interpretation of geological descriptions was necessary and the down hole geological log file (Paterson_geology.csv) contains unit names derived principally from the Geoscience Australia 1:1,000,000 geological map of Australia (Raymond 2009). This was regarded as the fundamental starting point for placing geological materials into the known lithostratigraphy and most log descriptions are limited to the lithostratigraphic units defined in this map. Thus, most unit names are simple descriptions, e.g., “Rudall Complex”, “Broadhurst Formation”. A minority of company reports in the area of the Rudall Complex contained detailed lithostratigraphic descriptions, so every effort has been made to transcribe this detail. The original geological logs are available in each company report; the reader is referred to these for detail. Source reports are detailed in the Appendix. Drill holes logs in the database span at least four decades of geological understanding in the Paterson region and have been created by numerous workers with lesser or greater degrees of understanding of the lithostratigraphy of the region and the 3-dimensional relationships between the different age units. Equally, the materials logged vary from reverse circulation or rotary air blast drill cuttings to diamond core, so there have been different interpretations of similar materials between different reports. Every attempt has been made to interpret the logs within the most modern lithostratigraphic framework, however, describing post-Palaeozoic materials has been problematic, particularly when most drilling through these has used a percussion or reverse circulation method. Thus, in some areas, particularly around the Nifty Cu mine, Paleozoic and Mesozoic materials may be combined into a single unit in this database because they appear similar in drill cuttings. The logging geologist may not have appreciated their importance, as they represent a progression of materials reworked from older to younger deposits, and may not have described them sufficiently to allow them to be separated with confidence in this database. Similarly, a small number of logs included in the geological log file (Paterson_geology.csv) have descriptions limited to “Yeneena Basin” (Neoproterozoic), because original descriptions were too poor to allow accurate discrimination to Formation level.

4 Database description The drill hole database consists of four individual tab-delimited .CSV files containing over 6,500 individual drill hole collar locations (Figure 2), basic geological logs for over 4,300 drill holes (Figure 3) and down hole surveys where available. The frequency distribution of drill holes versus depth range is shown in Figure 4. The common field between the three drill hole files is the company-assigned drill hole name, “Hole_ID”. Data column headings for individual files are:

Drill hole collar locations (Paterson_collar.csv), Table 2; Down hole geology logs (Paterson_geology.csv), Table 3; Down hole survey (Paterson_survey.csv), Table 4; and, Rock codes (Paterson_rock_codes.csv), Table 5.

The database contains information for holes greater than 20 m total depth only; shorter holes have been excluded. Short holes offer little information in a regional context and similar information can be gained from geological maps at 1:100,000 and 1:250,000 scale. Data are tabulated in a format that can be easily read into a wide variety of drill hole plotting programs including TargetTM and DiscoverTM and various mine planning programs like VulcanTM, MicromineTM and SurpacTM. Of the over 6,500 individual drill holes in the collar locations file (Paterson_collars.csv), down hole geological logs have been entered for approximately 4,300 (Paterson_geology.csv). Time restrictions and changed strategic objectives did not allow the completion of the data entry for this part of the project. Users are referred to individual reports in the WAMEX database to obtain the remaining logs, listed in the Appendix. 4.1 THE DRILL HOLE COLLAR TABLE The drill hole collar table Paterson_collar.csv (Table 2) contains attributes including the Hole_ID, WAMEX Report and Item numbers, depth, orientation, collar RL (metres above sea level), hole location in eastings and northings, comments and a sorting key. A number of holes were captured twice as they were documented in different reports. A ‘b’ was added to the ‘HOLE_ID’ of duplicate drill hole entries so that searches of the table would show the existence of two source reports. Hole_ID is used to link to the Geology table so duplicate entries with a Hole_ID suffix are not joined. In some cases exploration companies have re-occupied earlier drill holes using a different drilling method, therefore a small number of holes with a different Hole_ID have the same easting-northing coordinates;.

4.2 THE DOWN HOLE GEOLOGY TABLE The down hole geology table (Paterson_geology.csv; Table 3) contains attributes including Hole_ID (the primary join to other tables) and interval descriptions of geology, water table depth and descriptions related to the Geoscience Australia 1:1 M Surface Geology of Australia Map (Raymond, 2009). Geological descriptions are taken from company logs, but are augmented from the 1:1 M geology map where data were lacking. The SIMPLE_STRAT column contains three unique values related to the location of the economic basement: ‘basement’ (Archean and Neoproterozoic economic basement rocks); ‘cover’ (Permian and younger materials); and, precollar (undefined). The MAP_SYMB_1M, UNITNAME and LITH_DESC attributes are populated with rock and material descriptions initially as provided in the source drill logs, but descriptions are also taken from the Geoscience Australia 1:1 M Surface Geology of Australia map where source logs described intervals in terms of stratigraphic names only, e.g., ‘Paterson Formation’. The ASSOCIATION attribute was added to extend selection functionality by providing a stratigraphic parent grouping with allowable values:

Cenozoic sediments Cenozoic and Permian sediments (undivided) Mesozoic sediments Permian sediments Disappointment Group Tarcunya Group Paterson Province Yeneena Supergroup Throssel Range Group Lamil Group Rudall Complex Fortescue Basin

4.3 THE ROCK CODE TABLE The rock code table (Paterson_rock_codes.csv) contains the unique listing of the alpha/numeric code (CODE) from the down hole geological log table (Paterson_geology.csv) and corresponding lithological descriptions (DESCRIPTION) as recorded from the exploration report logs. Where only lithological descriptions were provided, codes were assigned from the Geoscience Australia 1:1 M Surface Geology of Australia map. In some cases a single code was used at differing times by companies to represent different materials. An incremental suffix number has been added to CODES with differing DESCRIPTION in order to ensure uniqueness and also provide a recognisable link with that in the source report. The DESCRIPTION attribute, as recorded from the company drill logs, inconsistently records either materials (e.g., grey clayey sand) or interpreted stratigraphic units (e.g., Paterson Formation). This inconsistency has been addressed to some extent in the down hole geological log table (Paterson_geology.csv) through the LITHDESC attribute. The rock code table includes an RGB lookup code for colouring intervals according to the Geoscience Australian 1:1 M Surface Geology of Australian map in Target/Oasis Montaj using the PATTERN, PAT_SIZE, PAT_DENSITY, PAT_THICKNESS, COLOR and BACK_COLOR attributes. The final attribute column SORTNO allows simple ordering of the table into geological Period groupings. Table 5: Rock codes file column headings (Paterson_rock_codes.csv). COLUMN HEADING DESCRIPTION
