1 BACKGROUND INFORMATION The Queensland Exploration Geochemistry and Drill hole database is a

comprehensive record of information extracted from the hard copy open-file company reports archived in the Geological Survey of Queensland’s Queensland Digital Exploration Reports (QDEX) system. The October 2016 Version of the database combines the original data compiled by Terra Search Pty Ltd and the data updates compiled by Map to Mines Pty Ltd. The database comprises 5,248,102 data points covering three hundred and two (302) 1:100,000 maps sheets. The various map sheets contain varying sample density and sample types. Table 1 summarises the data coverage and the spatial distribution of data points listed by 1:100 000 map sheets. The data have been carefully validated with respect to the spatial and data entry accuracies reported by the various companies. The types of data included in this database are drill hole locations, down-hole assays and geology, and assays of rock chips, stream sediment, soils and whole rock samples. All data points are linked in a matrix of relational tables and libraries, particularly in regard to location, sample type, analytical results and methods, etc.

The Geological Survey of Queensland, Terra Search Pty Ltd and Map to Mine Pty Ltd attempt to provide the most accurate data spatially and scientifically. Inevitably, locations digitised from hard copy maps have some degree of inaccuracies reflected by the ‘location accuracy’ field. All data have been attributed with locational information (Eastings/Northings and Latitude/Longitude), and all local grid coordinates reported were captured in this database. All locational information is converted into AGD66 Datum (AMG projection) in this database. If the original datum was not provided on maps or quoted or in reports, it was assumed based on the age of the report. Methodologies for sample preparation and analysis were recorded for all geochemical data based on the original laboratory certificate, result tables or summarised in the body of the report. In the absence of such information or insufficient information, the methodology was either quoted as “unknown” or guessed based on the laboratory code and profound methodology used by certain laboratories at the time. All data points within the database are individually linked to the original company report references (CR number) and if in doubt, it is always advisable to refer to the original document for confirmation.

The current database includes portable X-ray Florescence (PXRF) data. As PXRF data are highly dependent on instrumental settings and models, the lower detection limits are arbitrary. PXRF data are compiled as submitted in the company reports which may include ‘zeros’ for data below detection as reported, and data should be use with care.

The Queensland Exploration Geochemistry and Drill hole database is delivered in two formats – a statewide single MS ACCESS database, and a package of 5 geographic based database blocks.

1.1 Statewide MS ACCESS Database

The statewide database is delivered in MS ACCESS only. As the database exceeds the MS ACCESS storage limit, the database is broken down into 3 MS ACCESS files as:

1. tsxpldat, 2. tsxpldat2, and 3. tsxpldat3.

To link the 3 MS ACCESS files, Map to Mine Pty. Ltd. (MTM) has supplied the following instructions.

How to link the database files to see all the data in the one database (MTM, 2017) Due to the limitations of access databases only having the ability to store up to 2GB of data, the 100% merged database has had to be split into three access .mdb files. The file “link” recognises the file path address, which means that every time you move the data, the links need to be told where to get the information from. It is only the surface data that needs to be linked. Here are a few simple steps to help set this up once the data is migrated off the hard drive.

1. Right click the left hand tables list panel and select ‘Link Table Manager’ (see below):



2. This will open up a dialog box with showing a list of all linked tables.

Due to the size, the linked tables are located in two databases. tsdpldat2.mdb contains tables: tsdpldat3.mdb contains tables: s_Dating s_Soil s_Dating_Lith_Param s_Soil_Lith_Param s_Geology s_Soil_Param s_Geology_Lith_Param s_Structure s_Petrology s_Structure_Lith_Param s_Petrology_Lith_Param s_Wholerock s_Photo s_Wholerock_Lith_Param s_Photo_Lith_Param s_Wholerock_Param s_PIMA s_Wholerock_Trace s_PIMA_Data s_PIMA_Lith_Param s_Program s_Program_Lith_Param s_RC s_RC_Lith_Param s_RC_Param s_Seds s_Seds_Lith_Param s_Seds_Param As there are 2 databases linking to the main database the process will have to be completed twice, but once it has been re-linked at its final storage destination, the process should not need to be repeated again.

3. In the tick boxes to the left (see image below), select the tables in the above list to the left (all the files that have ‘\tsxpldat2.mdb’ at the end of file path name in the linked table manager window).



4. Click “OK” 5. Find the access database file: ‘tsxpldat2.mdb’ in the system (see below) and click

“OPEN”



6. After you have clicked ‘OPEN’ it should tell you that all the tables were successfully linked/refreshed.

7. Repeat steps to link ‘\tsxpldat3.mdb’ tables i.e. In the tick boxes to the left, select the tables in the list to the right (all the files that have ‘\tsxpldat3.mdb’ at the end of file path name in the linked table manager window) and then click “OK”.

8. Find the access database file: ‘tsxpldat3.mdb’ in the system (see below) and click ‘OPEN’

9. After you have clicked ‘OPEN’ it should tell you that all the tables were successfully linked/refreshed.



10. Click ‘OK’ and then click ‘Close’ to close the dialog box and the tables should open as normal in the database.

1.2 The Five Data Packages

The Queensland Exploration Geochemistry and Drill hole Data has also been geographically subdivided into five database blocks (Figure 1) as:

1. The South East Queensland block, 2. The Central Queensland and Drummond Basin block, 3. The North East Queensland block (including Georgetown Inlier, Hodgkinson

Basin, Ravenswood and Cape York blocks), 4. The Mount Isa Eastern block, and 5. The Mount Isa Western block.

The different data packages are of different sizes as summarised in the table below:

Database Size

The South East Queensland Block 6.0 GB

The Central Queensland and Drummond Basin Block 6.4 GB

Each data package is delivered in the MS ACCESS, CSV and MS EXCEL formats

and also includes ArcMap shapefiles. The MS ACCESS database is readable using the Explorer 3 database management software distributed with the database that allows reporting and export options, but does not allow edits, deleting or adding. Terra Search Pty Ltd owns the Intellectual Property of the Explorer 3 system and the licence to the full-version of the program.

Query fields that are inaccessible to this cut-down version of Explorer 3 are greyed out. The read-only Explorer 3 allows:

• Effective interrogation and sub-setting of data.

• Exporting to spreadsheet.

• Standardised geological codes and authority tables. Figure 1: The Queensland Exploration Geochemistry and Drill hole database subdivided

into five database blocks



2 DATA PACKAGE DOWNLOAD 2.1 Components of individual data package

Within each database package, there are 5 sub-folders of related files or data. The subfolders are:

Access\ PSWD.txt tsxpldat.mdb Data file tsxplimg.mdb Image file tsxplsys.mdb System file

CSV\ For users who work with Ascii tables or want to have a quick overview of data. The CSV files are linked to the shapefiles. Explorer3 exports Ascii data extracts, and the export files will have the same name as the CSV files. ArcMap project has been generated for each package using CSV files extracted from the database. As long as the file exports have



the same name, the linkage between CSV and Shapefiles will automatically display the data within an ArcMap environment.

EXCEL\Key data types from the database Explorer 3 Setup

A read only data management system (32 and 64 bit) that links the various table within the database. Users have the option to install and interrogate the data using the Explorer 3 program, or to link the various ACCESS tables outside the Explorer 3 environment. The full-version of the program remains under licence to Terra Search Pty Ltd.

Shapefiles\ Readme_2016.PDF A document to assist users on how to use the Explorer 3

program. 2.2 System and memory requirements

Minimum operating system is Windows 98. Installation of the Explorer 3 data management system: 220 MB The additional memory requirement for the download and installation depends on the size of the database package.

2.3 Installation instructions

1. Download your database block into a single folder area and unzip any files if necessary.

2. Use the ‘Browse’ function to locate the ‘Setup.exe’ program from the ‘Explorer 3 Setup’ folder, and run the setup program. If you have downloaded multiple blocks of the Exploration Geochemistry database, you only need to install one Explorer 3 program though each data block includes the same Explorer 3 sub-folder.

The setup program will install the Explorer 3 RDBMS program in a default directory called C:\Program\Explorer 3. However, if you wish to customise the destination, you can change the folder by using the “Browse” button. The “Browse” button activates the “Choose folder” dialog box where you can type in your customised data folder. You will need approximately 220 MB free memory to install the entire data management system.

2.4 Data folders

The setup program will create four subfolders under the folder you have created i.e. C:\Program\Explorer 3\. The subfolders are:

Data\ MapInfo| Temp\ Tutorial\

If you intend to download multiple database blocks, you need to create individual folders for each database, e.g.



q SEQ\: (South East Queensland block) q CQ_RB\: (Central Queensland and Drummond Basin block) q NEQ_RB_CY\: (North East Queensland, Ravenswood and Cape York block) q MIE\: (Mount Isa Eastern block) q MIW\: (Mount Isa Western block)

The MapInfo\ and Temp\ subfolders are empty folders created for storing Readme.PDF document and working tables and files. The Tutorial folder contains simple introductory exercises to the Explorer 3 regional database management system.

3 GETTING STARTED

Once the Explorer 3 file management system has been installed, the program can be run from the ‘Start’ menu by clicking on the ‘Programs’ folder, followed by “Explorer 3 RDBMS” option under the ‘Explorer 3’ folder. When starting up Explorer 3, the file management system will prompt you for the database directory.

For ‘Access’ database, you can choose any of the last six Databases previously accessed or browse for the new database location using the ‘Browse’ function. The main database is tsxpldat.mdb with the system and image databases being called tsxplsys and tsxplimg respectively

For SQL Server you can choose a ‘DSN’ name setup using the ODBC32 Configuration program. You may need to install the SQL Server Driver from the Data Access objects section of the Microsoft Office CD. There are three database objects for each Project Database setup and these should all have the same prefix with suffixes of _DB for the main DB, _SYS for the System Database and _IMG for the image database respectively.



Selecting database types: Access or SQL

3.1 User name and password The system will ask for a user name and password.

The default user name is “DBA” (uppercase). The default password is “AMIRA” (uppercase).

If the data files are to be accessible over a network, a file called PSWD.txt in the C:\Explorer3\Data folder has been included, which contains the encrypted password to the system. This file will retain the same “DBA” user name and “AMIRA” password.

User name DBA (uppercase) Password AMIRA (uppercase)

3.2 Help files

Help files contain instructions on how to use the Explorer 3 system and information on the tables and fields within the database. There are separate help files located under ‘Help’ in the main toolbar. The help topics are specific to the tasks and are listed below:

Main Menu Database Tables General Information Exporting Reporting Tools System Settings

There are several ways of navigating to the help file: 1. By pressing F1 on any screen the relevant section of the help file should appear. 2. Click on the Help button on the top of the screen for this option. Under Help, there are

the ‘Contents, Index and Find pages that allows rapid access to information. 3. Scattered throughout the Help file, there are words or phrases that show up as green

underlined words. These are hyperlinks that will automatically take you to a help topic related to the word or phrase.

4. Some help topics have pictures associated with them, and clicking on various parts of the picture will take you directly to the related topic.

5. The arrow keys on the top of the screen will move you through the help files in a specified order and the Back button will move you to the last topic viewed.

4. THE DATABASE 4.1 Database structure - Tables

The database consists of approximately 160 tables, each containing between 6 and 100 fields. There are three main entities designated as “table” within the system- Data, Modules and Libraries Tables, which have complex relationships as depicted in Figure 8.

Database structure- Tables

1. The ‘Data Tables’ or sample-type tables contain the observed or analysed data for the

variety of sample types. 2. The ‘Modules’ tables consist of one to several tables containing information that refers

to groups of sample data. The Modules included information on: • Exploration Program: Project, Prospect, Company and Grid Details. • Tenement: Land Tenure information directly linked to the Sample Tables. • Bibliographic: Report and other source information directly linked to the samples. • Assay Analysis: Analytical details stored efficiently and exactly for all analyses. • Polygon: Storage of 2 and three dimensional bodies for analysis using GIS.

3. The ‘Libraries’ tables are authority tables for the many codes in the system. ‘Libraries’

tables are split into several groups: • Geographical Libraries: Includes all items defined on Geographical criteria such as

Countries, States, GeoRegions etc. • Geological Libraries: All assigned geological criteria such as Provinces,

Geological Units, Regolith units etc. • Lithological Libraries: Lithological codes including lithology, Descriptors and

Structures. • Mineralisation Libraries: Style, Amounts and Mineralogy of mineralisation. • Surface Sampling Libraries: Codes for subsetting data on broad sampling methods or

lithological types.

Data Tables Module Table Library Tables



• Drilling Libraries: Codes specifically for drilling tables such as Bit Types, Drilling Companies etc.

• System Libraries: Codes that are the basis for the system such as coding system, parameters etc.

•

tables 4.2 The Database attributes Datum: All data points are stored with AMG and Lat/Long as well as relevant local grid

coordinates. The locations are stored with reference to the AGD66 Datum (AMG projection). Within a GIS environment, the data can be converted other datum such as GDA94 (Projection MGA).

Location accuracy: The estimated location accuracy is recorded in the grid_ID library and

appeared as a separate field on the data tables. The locational accuracy is recorded as an absolute distance in metres eg. ± 100m.

Geographic criteria: These include the country, state, mapsheet, prospect name, geological

province, company collecting the data, and the project to which the data belong. These data are all stored on the sampling tables using 3 of the primary key fields - Prospect Code, Company Code and Sheet. These codes are linked to the Exploration Program Module, which contains all the information common to an area. These fields are part of the database index and most functions will be faster where these fields are defined.



Assay module: The assay results can be effected by:

• Sample collection method, e.g. bulk or selected digestion • Sample preparation method, e.g. crush or sieve, size of sample • Digestion method, e.g. total or partial • Extraction method, e.g. none or selective concentration • Analytical method, resulting in varying levels of detection limits dependent on

sensitivity of method e.g. flame AAS compared to graphite furnace (carbon rod) AAS finish.

In this database, the different sample collection, preparation and analytical methods were recorded.

4.3 Data Tables: Categories and subsets

The ‘Data Tables’ database is split into two major categories - ‘Surface Sample’ and ‘Drill hole’. The ‘Surface Sample’ is further split into the four main categories as ‘Soil Sample’, ‘Stream Sediment’, ‘Rock Chip’ and ‘Wholerock’ (Figure 3). These broad data divisions separate the data into different tables, with one table for each of the four surface sample groups and fifteen tables for the different sorts of drilling data potentially collected at different from_to intervals, down drill holes. Each table contains a data type variable, which allows further subsetting of data based on the sampling methods used.

Some of the major fields in the ‘Surface Sample’ database are explained further in the section below. 5.1.1. Company: A 3- to 6- character code to uniquely identify a company, and its wholly

owned subsidiaries and affiliates, and background information. The company code is used throughout the Explorer system - on the sample tables, the prospect code library, the company report and tenement library.

5.1.2 Prospect Code: This is can be up to eight letter code. The first two characters of the

prospect code refer to the company who collected the data, the second two are geographically based. Each prospect code is linked to a 100K sheet number. E.g. ABBM 8355 = AB 2 character for Aberfoyle Resources Limited

BM Bimurra 8355 Mt Coolon 100K sheet

Prospect codes are also cross linked to 1:250K sheet areas, geological provinces, subprovinces, GIS projection, and company and land block. Prospect Codes generated by the Geological Survey of Queensland commonly have the GS prefix and codes generated by Map to Mine Pty Ltd have the MM prefix.

5.1.3 Grid_ID: Each grid is assigned a code which is linked to the 100K sheet number to

give a unique code throughout the Explorer system. Grid_IDs appear in the Grid ID library where information on accuracy, nature of grid and common points relating local coordinates to AMG are stored. These common points have been used in grid transformations to compute AMG coordinates where necessary. Grid transformations have been performed with Explorer 3 software and cross-checked with at least two other independently obtained points. The estimated locational accuracy of the samples is stored with the relevant grid. Regional data plotted on base maps are also linked to the grid ID library entries eg. AMG2 refers to data replotted onto 1:25K film base maps and digitised to an accuracy of ±100m.

5.1.4 Sample Numbers: In the Explorer system the original sample number is honoured as

much as possible, including prefixes and suffixes if relevant. Occasionally leading zeros are inserted to ensure a running sequence. If no sample number is found, Terra Search assigns a simple running sequence. The key field links of company:prospect code:100K sheet:data type:mesh:sample number is unique in the Explorer system.

RC Standard exploration rock chip sample usually taken from a single outcrop or float. See sample_method, method_amount and lithology_type fields for more info.

TRENCH Trenched rock chip sample, continuously channel sample over identified intervals. 5.1.6 AMG Coordinates: Always quoted as a 7- character northing and 6 character easting.

The link to 100K sheet uniquely identifies the zone and therefore the coordinates. The datum for the data set is defined in the prospect code library.

5.1.7 North, East. Local grid north and east coordinates: Any local grid or line coordinates

from the original data are entered into these fields. In the case of large surveys collected on local grids these coordinates are used to generate the AMG coordinates by grid transformation. In other cases, e.g. regional traverse lines, they may be rough coordinates e.g. flagged or paced lines and are only useful for local geographical reference. In these latter cases AMG coordinates are obtained by replotting onto base maps and digitised.

5.1.8 Latitude/Longitude: Calculated from the AMG coordinates and AMG zone using MapInfo software and the projection. All data are referenced to the AGD66 datum.

5.1.9 Line_No (Soil File): Identifies the original soil traverse line number. Often distances along lines will be entered into the local grid coordinate fields.

5.1.10 Mesh: Records the original reported sieve size in mm or Tyler mesh. For fine fractions refers to under size e.g. -80#, -2mm; for coarse fractions refers to over size e.g. +20#. Additional information on coarse fraction often recorded in comments field e.g. -10#+20#.

5.1.11 Under_SI mesh and Over_SI mesh: Original report mesh sieve size converted to standard SI units and recorded in microns e.g. -80 mesh will appear as 180 (microns).

5.1.12 Bulk_Wt: Bulk weight in kg, often recorded for BCL streams, occasionally recorded for original pan concentrate bulk samples.

5.1.13 Lith 1, 2, 3: Lithology coded 3- to 4- character, uppercase, field decoded in lithology library. The codes used were designed with collaboration with AGSO.

5.1.14 Desc 11, 12, 12, 31 etc: Descriptions relevant to each lithology using Explorer 3 descriptor codes.



5.1.15 Lith_Desc and Comment: General pertinent comments recorded here, such as longhanded lithological information, site description, soil survey, notes, presence of old workings, sample descriptions. Comment is used for info relevant to sample treatment.

5.1.16 Collection_Method: This records available information for rock chips, sample method e.g. G for single grab, S for selected, C for continuous channel.

5.1.17 Method_Amount: For rock chip samples, records the amount in m or square meters

respectively of sample length or area as related to collection method.

5.1.18 Occurrence: For rock chips this is a separate field which records nature of sample occurrence e.g. O = outcrop, FLO = float. For stream and soil data, if info is available, occurrence info can be found in the Descriptor fields.

5.1.19 Lithology_Type_Code: For rock chip samples, this is a simple generic code to group lithology types e.g. R = bulk rock, B = breccia, G = gossan, V = vein.

5.1.20 Assay Fields: The results of individual assay determinations are recorded in the relevant element field. Repeat analyses are recorded as separate elements e.g. Au, Au1, Au2. The assay fields are number fields therefore less than detections are recorded as negative e.g. <2 = -2. Blank fields in the MapInfo files are recorded as zeros.

5.1.21 Element Units: The units adopted for all the element analysed have been standardised throughout database types facilitates the plotting, visualisation and statistical analysis of data. Some examples are listed below: Au On all stream sediment and soil tables for all data types - recorded as ppb. Au On all rock chip (and drill hole tables) for all data types - recorded as

ppm. Au_ppm Parameterised field for recording Au in ppm on stream sediment and soil

tables, if required. Au_ppb Parameterised field for recording Au in ppb on rock chip and drill tables, if

required. Ag Recorded as ppm on all tables for all data types. Ag_ppb Parameterised field for recording Ag in ppb on stream sediment and soil

tables, if required. Hg Recorded as ppb on soil and stream sediment tables. Recorded as ppm on

rock chip and drill hole tables. Fe Recorded as % in all data types. Cu, Pb, Zn, As, all other elements = Recorded as ppm in all data types.

5.1.22 Concentrate_Wt: Concentrate weight for stream sediment sample, refers to weight in

grams of concentrate obtained from panning. This figure is useful in combination with bulk weight to calculate a normalised value for panned concentrate samples.



5.1.23 Assay Jobs: Each batch of samples that can be identified as being sent to an assay lab is assigned an Explorer system assay job number. This field is linked to each sample and also to a series of libraries which identify the lab, date assayed, analytical methods (preparations and techniques), detection limits and units for each element. Any batch that differs because of any of the above parameters is then assigned a unique assay job number. When the original lab batch number is known, this is utilised and recorded in the job number and old job number field. The assay job is also linked to company report and tenement. Assay Job and Assay Job Number codes generated by the Geological Survey of Queensland commonly have the GS prefix and codes generated by Map to Mine Pty Ltd have the MM prefix.

5.2.24 Company Report & Tenements: Each sample is linked to the company report and the

tenement that the original data are sourced from. Explorer 3 preserves the original company report (CR) number and tenement (EPM) number. The database includes a company report library which links the various exploration reports to the individual samples. Within the library entries there are notes (see summary field) that Terra Search have made whilst reviewing the exploration reports together with additional key words relevant to our data compilation.

5.1.25 Open File Flag: Identifies through a ‘Yes’ flag that the particular sample is from the

open file company report system or public domain as opposed to a ‘No” flag for closed file from a confidential source.

5.1.26 Tag: This field allows the user to tag samples derived from a search and flag them

with an entry in the tag field. 5.1.27 Parameterised Fields: These fields are utilized to cover any data that do not fit into a

fixed field. A list of these fields is found in the system library section under lib_parameters. Examples would include rarely analysed elements e.g. Sr, Rb or Au

analytical systems e.g. Au_wt (weight of gold in alluvial analysis etc.). 6. DRILL HOLE DATA 6.1 Drill hole data

The drill hole data acquisition has concentrated on recording of location, assay and survey information. There has been no concerted effort to capture geologic information across the various mineral provinces of Queensland. Within the Explorer 3 database, drill hole data are entered onto a series of relational tables and libraries. These are:

• Hole location table that records location, and may include information such as drill-rig type, depth of transported cover, water table, logger, dates, company report, tenement etc.

• Sample table which holds assay data. Similar to other sample tables, recording all assay results and through the assay job field and libraries records all analytical methods, detection limits, labs, dates, and units.

• Survey table which records all downhole survey information. • Hole text which records text details such as reason for drilling hole, results and

comments, including material left downhole.



• Down hole geology which stores all lithological, textural and geological descriptive information in coded form, including regolith profile and regime. Decodes are recorded in the lithology, texture and mineralisation libraries. Stratigraphic information is stored in the dominant unit library. The down hole geology is incomplete and may include:

o Percussion drilling details such as hammer sizes and type of drilling o Core size details recorded in the core size tables.

6.2 Drill hole data source

The drill hole data sources include logs, sections, plans and report text. Information for each drill hole is listed according to the following fields.

Hole ID Prospect code (assigned by Terra Search) 100K sheet Hole data type (DD, PERC, BEDRK etc) EPM and company report no. Final depth Collar elevation Depth of transported cover Completion status (completed, abandoned etc.) Survey (collar and downhole) Percussion and cored intervals

Addition information may include: Local co-ordinates, grid information and locational accuracy Base of oxidation Water table Geologist Dates of drilling Drill rig and company Assay data, including assay laboratory, methods, detection limits. All assay results for holes were entered into the database.

7. DATA INTERROGATION USING THE EXPLORER 3

PROGRAM 7.1 Database search

The Explorer 3 RDBMS database management system is designed as a state-wide data repository, both for recording and data retrieval. Its design encompasses all possible geological data types, geologic codes, assays and field observations. The pull-down menu for Prospects, Company, Mapsheet, etc. includes the state-wide listing, and can be very confusing. It is therefore essential to use known local parameters (e.g. 1:100,000 mapsheets, companies or prospect) or geochemical targets (e.g. Au>1000 ppb and Cu>500 ppm) to interrogate a specific database.

7.2 Designing a database search using known spatial or Prospect information The list of suggestions below sets out a simplified search procedures for first-

time users of the Explorer 3 program. The search focuses on a particular data set with known spatial and prospects information (listed in Tables 1-5, Figures 2-6).

Steps 1. Load the Explorer 3 RDBMS program from the Start Menu.

2. From the ‘Data Table’ on the Menu Bar, select the data type (i.e. either Surface

Samples or Drill hole samples)

3. Choose the type of data subset (e.g. Stream Sediment) from the major data subdivision (i.e. Surface Sample in this example).

4. By choosing a data subset, a query table with multiple fields will appear (as shown

below). (The cut-down version of Explorer 3 has limited application and greyed out keys are functions not available for use in this database).

5. Using a fixed parameter or a combination of parameters for the search.

For a location-based search, mapsheet references listed in Table 1 and Figure 1 provides a spatial constraint that focuses on an area of interest. Enter the mapsheet number into the ‘Sheet’ field on the Site Information table, and click the ‘Search’ button (bottom right corner).

Explorer 3 will list all samples located within the mapsheet e.g. “Record 1 of 3500” (at the bottom of the table). The arrows at the bottom left of the Table can be used to scroll the record individually (>), in 10s (>>) or to the end of the record list (>|).



Example of the query table in Explorer 3

Using 1:100,000 mapsheet number as a spatial constraint for search

Example of search result for stream sediments samples in Mapsheet 9345

STEP 2 Choose the type of data of interest: - Surface Sample - Drillhole

STEP 3 Select the type of sample or interest e.g. Stream Sediment

STEP 4 The Surface Sediment Samples query table which appear will require search parameters to be entered.

STEP 5 Enter the 1:100,000 mapsheet number for an area of interest, and hit the search button on the lower right corner. Such generalised search recalls all the sample of the chosen type in the mapsheet



6. a. If more than one mapsheet or sample type is involved, the ‘Global Filters’ function can be used to define the list of maps for searching. To activate the Global Filter, double-click the Global Filter box (Steps 6a) to generate the Global Filter Dialogue Box.

b. Select the Database or Project to be interrogated. In this database package, the ‘Project’ has been defined, so by clicking the top double arrow (Step 6b) will transfer the ‘Project File’ from the top left box to the top right box (i.e. the database used in the search).

c. Choose the type(s) of data (Mapsheet or Prospects and Company) as parameters for search (Step 6c). Having defined the type of data, a complete list of information for the data type will appear in the lower left box.

d. Highlight the specific data e.g. mapsheet of interest and use the single arrow (>) to transfer that particular information into the right-hand field as the parameters used in the search (Step 6d). Repeat the procedure to include other mapsheet and/or Prospect and Company information.

The >> arrow selects all data within the dataset to be interrogated, and is a useful function to display the spatial distributions of data points within a region.

The < and << arrows deselect information previously included in a search. The single arrow (<) deselects individual data whereas the << arrow deselects the entire data previously elected for searches.

The Global filters will remain active and the defined sets of parameters can be used in other data type searches e.g. Soil Samples, Drill holes etc. To remove the Global Filters function, uncheck the Global Filter box (highlighted in red when active).

7. Using Company or Prospect Names for the search

Similarly, searches can be based on Company names or Prospect information. The complete lists of Company and Prospects names and their accompanying Codes for the Exploration Geochemical/Drill hole Database are tabulated in the library tables.

Enter the Company or Prospect Code (Step 7) into their respective fields on the Site Information table, and click the ‘Search’ button. Explorer 3 will list all samples collected by the specific company or Prospect within the region.

Similarly, the ‘Global Filters’ function can be used to define the list of Companies or Prospects, if more than one company/prospect of interest is involved.

STEP 6a Double-click the Global Filter box to activate the dialogue box.

STEP 6b For a defined Exploration Geochemical/Drillhole dataset, the project has been defined and click the double arrow to include the data within the database for search.

STEP 6d List e.g. the mapsheet(s) for data interrogation by highlighting the sheet number, followed by the single arrow. The right field is the list of mapsheets for data search.

STEP 6c Select the Data Type

MOVE



Example of search using Prospect or Company information

7.3 Designing a database search using Assay results

Instead of using fixed parameters such as mapsheet, Company or Prospects, available assay results can also be used in searches, particularly to establish areas of geochemical anomalies. In the dialogue box, use the pull-down menu associated with Assay to determine the Field or element of interest e.g. Au. In the Value field associated with the elemental field, first establish the geochemical limits used in the search e.g. >1000 ppb. Multiple elements can be used to define a geochemical search.

Having established the geochemical constraints, hit the Search key to activate a generalised search for the entire database for the combined limits set by geochemical assays i.e. Au and Cu, as in this case.

7.4 Other information

The Exploration Geochemical and Drill hole database may contain relevant information related to a data point, company background or tenure. Such information is linked to the Data tables by the Modules or Libraries tables, and is included in the report(s) of such data. Data contained in the Modules and Libraries tables can be searched using known parameters such as mapsheet, prospects or company reports listed in the library tables. Data complied by different compliers are identifiable from the prefix in the TS_Release codes. QDRM refers to Terra Search Pty Ltd, MM refers to Map to Mine Pty Ltd and GS refers to the Geological Survey of Queensland.

Database Search Using Assay Results

STEP 7 Enter either Prospect Code or Company Name using the pull-down table. Press the Search button to activate the search.



8. REPORT AND EXPORT The instructions for Reporting and Exporting functions are documented in the Help Menu. The following sections are extracts of the Help Menu to provide quick overviews of some of these functions. There are several Reporting options for the various tables. The main report options are for reporting the data as ledgers. There are also reports available for the reporting of lithological data, drill hole summary reports and project and prospect summaries, which contain a summary of the data within the database for a particular prospect or group of prospects. The methodology of setting up the reports is similar for many of the reports and the choice of fields for reporting and the loading of existing report setups is identical to that of the exporting functions. 8.1 Reporting surface samples table

There are few options when printing surface geochemical samples. A ledger format is normally the most suitable format to present this information.

For Rock Chips the geologic information is often more detailed and important for the analysis of the data and there is not only a ledger style report but also a decoded geology report.

The data to be reported should be queried using the main surface sampling forms. Once a suitable dataset has been retrieved, the print button on the Toolbar or the reporting Button on the Power Bar should be pressed to bring up the relevant options.

8.1.1 Ledger reports

Step 1. Use the pull-down menu in the ‘Field’ column, establish the element to be used as discriminant for a database search.

Step 2. In the Value column associated with the Field, establish the limits used in the search

Step 3. Other elements e.g. Cu can be included to further refine the database interrogation..

4. Search



The ledger report contains a fixed header that is printed at the top of each page that includes details of the prospect, sheet, data type and company collecting amongst other broad groupings. When any of these change from one sample to another, a new page is started. The fields printed in a ledger are user defined and can be chosen using the provided lists (Fields). If there are too many fields to be shown on a single page, the system will automatically move the extra fields to a second page. By ticking fixed in the last column the chosen fields will print out at the beginning of each page required for the sample. The unit’s column can be used to define the units you wish to report an element regardless of the units it is stored in. The program will automatically convert it.

Report Generator table using user-defined ledger

8.1.2. Decoded ledger

For rock chips a second option is available. This report takes the full coded geology from the sample and translates it into text. This is then reported along with all the location details and a select number of geochemical results. This report can only fit 2 to 3 rock chips per page and would not usually be used with large datasets.

8.2 Reporting drill hole table

There are several different reports available for the drill hole system. These include an intercept report, downhole ledger and drill program summary. There is also a drill hole report, which summarises the entire hole.

The dataset reported on is generally chosen by querying the data required on the drill hole form. By pressing print or the reporting button the various options for printing appear. These options vary slightly depending upon which tab you are on.

8.2.1 Ledger reports

Using the Ledger option, define the headers in the left box to be included in a report. Highlight the header and then use the arrow > to move the field into the right hand box.

User-defined headers to be used in a report.



The ledger report contains a fixed header that is printed at the top of each page that includes details of the prospect, sheet, data type and company drilling amongst other broad groupings. At the top of each hole there is also a summary of the collar location, hole ID, survey details, etc. There is an option to start a new page for each hole or to continue on to the next hole directly below. The fields printed in a ledger are user defined and can be chosen using the provided lists (Fields). If there are too many fields to be shown on a single page the system will automatically move the extra fields to a second page. By ticking fixed in the last column the chosen fields will print out at the beginning of each page required for the sample.

8.2.2 Program summary

The drill program summary report takes a set of queried collars and produces a one line summary of each hole including coordinates, dip, azimuth, total depth, pre-collar depth etc. It then calculates the total metres drilled for a program and the total number of holes. The fields in this report are fixed and are designed to be a fast method of getting information for reports or project planning.

8.2.3 Drill intercept report

The drill intercept report is designed to take the higher assay results from a drill hole and work out the width and grade of a particular intercept. The report works on the tagged samples from the queried drill hole collars. For instance, this allows you to tag all the downhole gold values greater than 0.5 g/t and the program will automatically group together any adjacent, tagged samples to form an intercept. The average grade is then calculated over the intercept. Care should always be taken when using this report to ensure the calculated value is correct or using data that may be misleading. The assay value units chosen (e.g. ppm, ppb) for the elements would be the units displayed on the report regardless of the units they are stored in the database. These are recalculated based on the units stored in the assay job details - if there is not a valid detail for an assay job then the program assumes the units are the same as those chosen.

8.2.4 Drill hole summary

The Drill hole summary report attempts to collate all the critical information collected on a drill hole and display as a one or two page report. The information retrieved includes the collar information; survey details, water table and details on the base of oxidation, reasons for drilling the hole, summary geology, significant intercepts and a summary of the results of the hole. This is designed to give a concise description of the hole for reporting or management purposes. It requires detailed data entry for a hole, which will allow full retrieval of information on a hole without having to search through several reports or files. For this purpose, one can choose either ‘Descriptive geology’ table or the ‘Coded Geology’. If you choose ‘Descriptive geology’ then you must choose which fields to display. The assay section reports only on the tagged samples for a hole and you can have the choice of either a sample ledger or a drill hole intercept style output.

8.3. Reporting data analysis The data within the explorer system is grouped into prospects and projects. The

prospects can be queried in the prospect library under the Exploration Program Module menu item. Any field in the table can be used to query a required group of prospects. Once queried there are two reporting options available:



8.3.1 Data Inventory

This report gives a list of all data present in the database for each of the prospects queried. Each prospect is given a header summarising the prospect details and then a list of the various data tables and the numbers of each data type within the prospect. There is an option not to report on data tables which have no data in them, the default is to show all tables and annotate those empty tables as having No Samples.

8.3.2 Prospect Summary

This option gives a summary list of the queried prospects along with their prospect names, followed by a summary count of all the data contained within the whole group. Once again you can choose whether or not to display the data tables with no data or not.

8.4 Exporting data

There are several ways of exporting data from the Explorer system. The data sets being exported can be chosen using the basic querying functions for any of the main data tables. The export button on the Main Tool Bar is pressed to give a list of exports available. Data can be export directly into either ASCII or HTML format. These are saved based on the fields chosen in the list view configuration. The available formats for export are:

• Micromine • Access • Replication • ASCII • Rich Text Format

If there are no query forms open, options for broader exports are available using the Export Query Screen. This form must be used for the Replication Export Options. 8.4.1 Export Query Screen

The screen below is the query screen for querying large amounts of data, based on any combination of the criteria below.

The choice of “All” limits the exports to an Access database export or a Replication database export. The choices of the other tables allow all export options.

You can define the subset of data required using a whole project or any combination of Company, Prospect or Sheet Number. By placing an asterisk “*” in the field the export will search for any matching entry. You can also use the normal querying functions such as logical operators within these fields

Having set the criteria you can move to the next stage by pressing ‘continue’. You can also abort an export at any time using the cancel button



Export Query Screen

8.4.2 Picking Fields for Exporting

The method of choosing the fields for exporting, and the order exported, is the same as choosing the fields for reporting. A list of available fields for export can be chosen by clicking on the field name and then the > button. This will move the field to the bottom of the list. By pressing the >> button all fields in the list are selected. Similarly remove fields from the export field list by selecting the field and pressing the < button. It is possible to remove all fields by pressing <<.

To move a field up or down in the order highlight the field you want to move and then press the Up or Down buttons to change the order.

You can save an export setup by choosing the “save” button on the bottom left of the screen once you have defined the fields and order you want. You can name the setup using any name you wish, with or without blank spaces, with up to 50 characters. It is best to give the setup a name suggestive of the data type and elements exported such as “Mt Isa Stream_Base Metals”.
