8 Tutorial 1: Getting Started

Tutorial 1: Getting StartedIn mineral exploration, the initial focus of any exploration program is to identify

potential targets for drilling. After potential targets are determined, the project movesinto a proving phase led by a geologist experienced in obtaining and interpretingdrillhole data. A complete drilling program will acquire many types of data rangingfrom hole location (i.e. collar details), surveys (i.e. 3-Dimensional orientation),geologic rock types and descriptions, drill hole geochemical assays and boreholegeophysical logs.

To set the stage for a successful subsurface data acquisition program, the geologistrequires knowledge and experience plus effective tools that facilitate organization,

planning and most importantly, visualization and plotting of data in 3 dimensions. A3-dimensional perspective is essential to evaluating geologic structure of mineralizedand host rocks as well as determining the continuity of host and mineralized rocks. Inthis context, drill programs rely on surface plan maps and subsurface cross-sectionmaps to acquire the 3-D perspective required to prove potential targets.

The Target for ArcGIS system was developed to provide the geologist with:

Minimum curvature and Krigrid (statistical) gridding routines as well as Geosoftscomprehensive contouring tool

Organizational tools (consisting of versatile, self-contained databases and rockcode management)

Quality Control tools (including QA/QC tests on each of the five different datatypes; Collar Data, Dip/Azimuth Survey, Easting-Northing Survey, From-ToData, and Point Data).

Planning tools (such as plan maps and section outlines) Visualization and plotting tools (including comprehensive plan plots and section

plots in any orientation)

Gridding using Minimum Curvature GriddingTo perform minimum curvature gridding, you must supply X , Y and Data fields ,Output grid name and Grid cell size (optional). In addition, you also have a variety ofoptions, including the ability to:

Specify data limits and clipping Grid the original data or log of the data (using cut-offs or a data range) Specify desampling values (for low-pass filtering) and blanking distance (for

removing values beyond a certain distance) Specify the tolerance to which the minimum curvature surface must match the

data points. The default is 1.0% of the Z range of the data. Also specify the percentage of points that must meet the tolerance for the iterations for thecurrent processing step to stop

Specify the maximum number of iterations to allow Adjust the tension to produce a true minimum curvature grid or to increase the

tension to reduce overshooting problems in unconstrained, sparse areas

The Minimum curvature gridding algorithm generates a grid file (*.grd) and gridreport file (rangrid.log).

Adding Data and Assigning a Projection

Target for ArcGIS enables you to grid shape files, event layers and table files.However, in order for the resulting grid to have a projection, you must grid either ashape file or an Event layer that already has a projection assigned to it. The grid willadopt the projection of the source data. ArcMap will not let you assign a projection toa table, so any grid created from an XY data table, i.e. not an Event theme or shapefile, will not have a projection assigned to it.

Tutorial 3: Target for ArcGIS Drillhole ToolsIn this section, we will guide you through the key steps necessary to start a newdrillhole project and import and verify geological and geochemical data. The

procedures in this chapter will show you how to:

Access the drillhole menus (page 27) Start a new project (page 28) Import data (page 30) Apply quality control and quality assurance tests to data (page 41)

Before you begin

This tutorial uses sample data provided on the Target for ArcGIS CD ROM. Beforeyou begin, save the files (Collar.csv, Assay.csv, Survey.csv, Geology.csv) to aworking directory, such as D:\Tutorial .

Access the drillhole menusThe Target for ArcGIS drillhole menu options and plotting tools can be found on theTarget Drillhole toolbar. For more information on the Target toolbars and the menuand plotting tools available, see page 98.

Note: The drillhole system uses a special window within ArcMap to create andview Geosofts unique three -dimensional databases. The Geosoft DatabaseWindow is specifically designed to enable users to access their drillholedata using organized and self-contained spreadsheet tab windows.


34/109

28 Tutorial 3: Target for ArcGIS Drillhole Tools

TO O PEN THE GDB W INDOW :

1. Select the Show Geosoft Database Window button ( ). The Geosoft DatabaseWindow will be displayed on the left, as a tabbed window.

2. As we have not imported drillhole data into the project the window displays theNo Geosoft Databases Loaded message.

Starting a New ProjectThe Target for ArcGIS drillhole system has been developed using Geosofts uniquethree-dimensional database structure. These databases are linked by a common

project name that provides easier data management.

When you start a new drillhole project the "Collar" database is created and displayedin the GDB Window . Each individual data type will have its own databases. Thecommon project name links the databases. For example, separate databases for collar,survey, assay, and geology are created and linked by project.


35/109


In a project named "Prospect" the following databases could be created:

Prospect_Collar.gdb (collar information) Prospect_Survey.gdb (hole dip-azimuth survey information) Prospect_Geology.gdb (geology information The Geology label is user specified)

Prospect_Assays.gdb (assay information - the "Assay" label is user-specified)Note: When the Target for ArcGIS system is used, it scans the open project for

all the databases currently loaded in the project to see which data isavailable. If you close one of the project databases, it will not be visible tothe system and will not be used when processing your data. While workingwith a Target for ArcGIS project, if you wish to hide one of thedatabases, minimize it instead of closing it in order that Target forArcGIS can continue to access it.

Naming a Drillhole Project

The drillhole project name will be added, as a prefix, to all of your project databases(collar, survey, assay, geology, and other types of related information).

TO NAME A DRILLHOLE P ROJECT :

1. On the Target Drillhole toolbar, select Target Project|New project . The Drillhole- New Project dialog is displayed.

2. Specify a New project name as ( Prospect ). The current default project directory isdisplayed in the Project Directory box. If this is incorrect, click the [Directory]

button to specify the correct working project directory (i.e. D:\Tutorial\ ).3. You can specify the Maximum holes as ( 1000 ) and you can leave the Maximum

data fields per dataset to the default value of ( 100 ). We recommend that youspecify a number that is representative of the final estimated project size. Thisstrategy ensures that you have enough space available in your project while notconsuming excessive storage space.

4. Click the [OK] button. The collar database with the project name that youspecified is created and displayed in the Geosoft Database Window .


36/109


Importing DataThe Drill Hole Import Wizard guides you through the import process, andautomatically displays your data in a Spreadsheet window. The spreadsheet windowis similar to Excel in appearance with specialized Earth Science capabilities,including built-in data manipulation tools.

The purpose of this tutorial is to help you become aware of the key components andcapabilities of the Target for ArcGIS import process to prepare you for plotting yourresults in plan and section maps. In this exercise, you will be importing collar, survey,geochemical assay, and geology data.

UPDATED ODBC IMPORT TOOLS

A new filtering capability has been added to our ODBC tools, for both accessingsurface and drillhole databases. Now you can access just the data that you needwithout the requirement for SQL query knowledge, both for our regular GeosoftGDBs, and for our Drillhole projects. This new capability will also enable you to

connect to other drillhole databases such as DataShed and Century systems.Current X and Y Channels

The Target for ArcGIS system has implemented current" X and Y (and Z)channels. This feature enables users to select the channels that they would like to useas the current X and Y (and Z) channels (for example, East, North, and RelativeLevel).

Markers have been added to the channel header to indicate which channels arecurrently defined to be the "current" X, Y (and Z) channels. The markers are littlerectangles on the right side of the header cell, and contain "x", "y" (or "z") in reverseddisplay (like the triangle protection symbol on the left). The "z" will be used inTarget for ArcGIS databases, where DH_EAST = "x", DH_NORTH = "y" andDH_RL = "z".


37/109


Importing Data Files

During drilling, the geologist acquires and integrates data from different sources andformats, including:

Drillhole locations - Collar information containing (at a minimum) Hole ID,Easting, Northing and Relative Level (Elevation). Note, that in the data example

below, the Azimuth, Dip, and Depth are also included in the collar file.

Surveys (Optional) Hole deviation information in either Hole ID, Depth,Azimuth, Dip format or Hole ID, Depth, Easting, Northing, Elevation format.

Note that, a survey file is only required if a hole has actually been surveyed andthe dip and azimuth change at depth.

From to Data From-To data is data acquired over specified depth intervalsdown the hole; for example, at a 1 m interval with a measurement starting at 0 mand extending to 139 m. In this tutorial, we will import two types of From-Todata: a geochemical assay dataset and a geological rock codes dataset.


38/109


Point Data Point data is data acquired in discrete measurements made at aspecific depth, for instance 85.6 m. In this example, a Geophysical property log(borehole geophysics) in Single Point data format.

The Target for ArcGIS system automatically detects the type of data that is beingimported, which can be any of the above.

There are two ways to define drillholes and add data to your project in Target forArcGIS :

Import data already stored in CSV/text or XLS/database data format. A commonexample is a geochemical assay file, which is commonly delivered to you on diskor via email by an assay laboratory in Excel XLS format. Depending on projectneeds, you may also initially have geological data, collar data or survey data intext or data files.

Manually enter data. If you are performing a grassroots exploration project, youmay only have one or two holes to work with initially. In this case, you may justwant to add some basic collar location or projected survey information to your

project.

In this part of the tutorial, we will work through the import process of collar, survey,assays and geology data from CSV files. The purpose is to demonstrate standard dataformats and show how Target for ArcGIS handles each of these situations.

Importing Data

The Target for ArcGIS system enables the import of data stored in CSV/text orXLS/database data format.

In this section, we will work through the import process of collar, survey, assays andgeology data from CSV format files. The purpose is to demonstrate standard dataformats and show how Target for ArcGIS handles each of these situations.

Importing Collar Data

When entering data in Target for ArcGIS , you must start with collar data. Thesystem creates a unique collar database that you can use to view all drillholes in the

project at a glance. You can also plot an initial plan map showing all holes for review purposes. A collar file must exist before survey or assay data can be imported, and before plans and sections can be created.

9. Click the [Next>] button to continue. The system displays the fourth and finaldialog box in the Drill Hole Import Wizard .

10. The Import Wizard has scanned your data and determined the type of data withwhich you are working (i.e. Channel Type ). It is always good practice to reviewyour data to ensure that the wizard has selected the correct columns. TheParameters area in the dialog box shows the name and type of data of the columnhighlighted in the preview window.

Note: The Data Type of Database Fields that contain alphanumeric data (forexample, sample numbers, rock codes etc.) must be classified as String .

11. Click the [Finish] button. The system imports the data ( Collar.csv ) and displaysit in the spreadsheet window. (Note: Ensure the Show Geosoft Database Window

button ( ) is selected, to display the imported data).12. At this point, we recommend that you examine the database carefully. Start by

confirming that all columns of data in the original CSV file are present in the

database.Note: If you have problems with your data file, the system will attempt to open

an ASCII file ( dhimp_collar.log ) and display a list of warnings or errors.If you have not yet configured a text editor in your system, you may be

prompted for one. In this case, search your system for your text editor (i.e. Notepad), which can be located in the Windows directory.


43/109


Importing Survey Data

Various types of surveys (acid, gyroscope, magnetic orientation, etc.) can be used torecord hole depth (depth measured from the drillhole collar). For Target for ArcGIS ,you can use survey data in one of two forms:

Before importing data, you must make sure that you have all fields as shown in one ofthese configurations (i.e. these fields are required on import).

By conventi on:

Depth is the distance measured into the hole from the collar, increasing from zero. Azimuth is in degrees, increasing positively in a clockwise sense from North (i.e.

N is 0 degrees, E is 90 degrees).

Depth, Easting, Northing and Elevation are in the same units as default units set in Data|Set Projection dialog. To change the units, click the [Modify] button.

TO IMPORT S URVEY DATA :

1. On the Data menu, select Import|Text file . The Drill Hole Ascii Import Wizard dialog is displayed.

2. Using the Browse button ( ), select the Survey.csv file from your workingdirectory and click the [Wizard] button. The system scans the file and displaysthe first of four dialog boxes from the Drill Hole Import Wizard . Note that thesystem has determined that the Data Input Format is ASCII Data . The Types of

Data to import should default to Dip-Azimuth Survey .

3. Continue clicking the [Next>] button and work your way through the remainingthree dialog boxes. Watch the sequence of screens and note the differences fromthe Coll ar I mport procedure.

4. In the final dialog box click the [Finish] button. The system imports the data(Survey.csv ) and displays it in the spreadsheet window.

Importing Geochemical Assay Data

Geochemical assay data are typically acquired by obtaining core or rotary drillsamples over specific depth ranges (From-To ranges) and sending samples to an assaylaboratory. Numerical results are typically returned from the laboratory in electronic

format and can be imported quickly into the system. Before import, you must makesure that your data files contain the following information HOLE ID , FROM , TO and a series of ASSAY results.

Note that, the Length Weighted Mean calculations have been added to the Statistics tools. By highlighting a selected section of your drillhole database (To-Fromdatabase), you can view the calculated Length and Length Weighted Mean values on


45/109


the Stats Report dialog. This makes it easy to quickly find out the length of severalirregularly spaced samples as well as the length weighted mean assay value.

TO IMPORT G EOCHEMICAL DATA :

1. On the Data menu, select Import|Text file . The Drill Hole Ascii Import Wizard dialog is displayed.

2. Using the Browse button ( ), select the Assay.csv file from your workingdirectory and click the [Open] button. The system returns you to the Drill Hole

ASCII Import Wizard dialog box and displays the file name you wish to import.3. Click the [OK] button. The system scans the file and displays the first of five

dialog boxes from the Drill Hole Import Wizard . Note that the system hasdetermined that the Data Input Format is ASCII Data. The Types of Data toimport should default to From-To Data .

46/109


Note: When importing Assay data all elements are assigned the Class Assay(Channel Type). Standards and Duplicates are also identified, enablingChimera Geochemistry users to extract the information using the normalChimera tools.

5. Before the import is complete, the system displays a fifth dialog box. The purposeof this dialog box is to enable you to specify a unique name or description foryour data. The name chosen will be appended to the corresponding holes in thedatabase for easier access and recognition of your data.

6. Specify a Data Name for this data and click the [Finish] button. The systemimports the data ( Assay.csv ) and displays it in the spreadsheet window.

Importing Geological Data

The system provides a versatile environment for adding a wide variety of geological parameters ranging from rock codes, extended text descriptions, alteration types,contact data such as fractures or faults, and other core log information that is

important in your drilling project.In general, this type of information consists of text but you can also add numericalvalues, for instance, if you want to retain numeric codes for statistical purposes or youwant to run your own advanced classification strategies in Target for ArcGIS .

TO IMPORT G EOLOGICAL DATA :

1. Repeat the steps in the procedure above, using the Geology.csv file.

2. You are now ready to begin working with your data. If this was a real project,more results can always be added later just as easily with the Import Wizard .

Saving your Databases

It is always a good habit to save changes you make to your databases, including new

databases.TO S AVE YOUR DATABASES :

1. Select the database you want to save, by selecting the Database Tab (as shown below).

2. On the Geosoft Database toolbar, select Geosoft Data|Commit Geosoft database

changes . Note that, you can also select the short-cut button ( ). The SaveChanges dialog is displayed.

3. Click the [Yes] button and the database will be saved to your working directory.

4. Repeat this process until all databases have been saved. Note that you can use theArrow buttons on the database tab to select the next database.

Quality Control and Quality Assurance TestsThe Target for ArcGIS system provides the tools to enable you to perform QualityControl and Quality Assurance tests on each of the five different data types (CollarData, Dip/Azimuth Survey, Easting-Northing Survey, From-To Data, and PointData).

The Drill hole - QAQC tools dialog asks you to select the type of data to perform theQA/QC tests on. For each data type there are different sets of options you can

enable/disable using the [Options] button.The individual QA/QC tests are run automatically during data import. Each test

produces its own log file; e.g. Collars (Collars.log), From-To (FromToData.Log), Alldata (QAQC.log). If no problems are found you receive a message such as: "No

problems were detected with the Dip-Azimuth Survey data."

For more detailed information on the options available for each data type see,Appendix 3: Setti ng QA/QC Options page 94.

TO R UN THE QA/QC TEST :

1. On the Data menu, select QA/QC . The Drill Hole - QAQC tools dialog isdisplayed.

2. From the Data Type to QAQC dropdown list, select the data type you want to perform the QA/QC test on. The using the Hole selection dropdown list, select theholes to perform the tests on. To see the list of options that the select data typewill use for testing, click the [Options] button. In this case, the QA/QC Collar

data options dialog is displayed.

3. Once you have modified your test options, click the [

4. Click the [OK] button to run the test. If no errors are found the Drill hole QA/QCdialog will be displayed telling you that no errors were detected.

5. Click the [OK] button to close the Drill hole QA/QC dialog.

Note: If you run this test on a data type that you do not have in your current project, for example in this case Easting - Northing survey you will be prompted with the Drill hole QA/QC dialog telling you No East -Northsurvey data exists in this Target for ArcGIS project and, if you run thistest on a data type that has some errors the data log file will be displayed inyour project, displaying the problem samples.

Composite Databases

The Composite Database option enables you to create a composite database from aninput From-To assay database. Using this option you can select the Interval selectionas ( Significant Intersections ), identifying drill core intervals that have significantassays based on minimum cut-off length and grade. This is useful for highlightingsuccessful drilling results visually within sections, maps or 3D views, and is

exportable as a tabular report.

Tutorial 4: Geosoft Map Layer and Shape FileOutput

The Target for ArcGIS plotting tools provides two types of output, ready-to-print

maps (Geosoft Map Layer) and Shape files. The ready-to-print maps contain pre-defined annotations, legends, as well as pre-attributed plotting objects. The Shape fileoutput includes database (DBF) files populated with attribute information related tothe plotted feature.

Geosoft Map LayerThe Geosoft Map Layer enables the user to pre -define colours, patterns, line-types,etc. using the tabbed dialogs. However, the Geosoft Map Layer is limited in thatthere is no GIS type interface using the Identify cursor, and the normal GISattribute and labeling tools are not available for modifying the created plot.Modifications are not allowed; if changes are required the user must create a new

plot.

Shape FilesThe Shape file output enables the user to create Shape files (SHP) for Plan, Sectionand Strip Log plots. Shape files are created for a variety of the plotted features,including the following:

Each of these SHP files includes database (DBF) files populated with attributeinformation related to the plotted feature. Some of the features noted above createmore than one SHP file; for instance topography is output both as a series of pointfeatures along the section line, which can be interrogated to determine the localelevation, and as a single line feature, which can be more easily attributed to usertastes for plotting.

Shape files can be loaded automatically into the current data frame, or manually input by the user using the regular import tools in ArcMap. When imported to the samedata frame as corresponding Geosoft Map Layer plan, section or strip log, the shapefiles overlay the map precisely and provide an instant GIS style interrogation of theGeosoft Map Layer features. [Note: This is not true for sections with verticalexaggerations not equal to 1 the transformations required to display these Geosoft

Map Layers also prevents the correct implementation of data linking.]

Tutorial 4: Geosoft Map Layer and Shape File 45

The Target for ArcGIS plotting tools provides two types of output, ready-to-printmaps and Shape files. Users can select to plot a Geosoft Map Layer, Shape File, or

both at the same time (at least one must be selected). Users are also provided with theoption of loading Plan maps and Section plots to a single data frame or to separatedata frames.

Quick Map - Load to separate data frames

For Plan Maps , the following frame names are created, depending on the trace typeselected under the Hole Traces tab.

PlanC Collars only

PlanT Full hole traces

Plan RL ZP Pierce point plots at level RL, e.g. Plan -20ZP is a pierce plot at arelative level -20.

Plan RL ZC Collars in a horizontal slice centred at level RL; e.g. Plan -20C.

Plan RL ZT Hole traces in a horizontal slice centred at level RL; e.g. Pl an-20T.Levels are rounded to the nearest integer value.

The same names are used to create the layers, with the optional addition of the Layer Name Tag, so a collars plot with the T1 tag would produce the following frame andlayer:

The following exampl e shows the difference between selecting Load to current data

frame and Load to separate data frames. A series of 4 pierce -point plots are produced, at elevations from - 30 to 0. The layer tag T1 is used.

Loading to separate frames: Loading to an existing frame:

(Note that, the frame has beenmanually named Pierce Plots)

Section plots are handled in an analogous manner. Section frames and layers arenamed based on the section reference location, at the section centre. The first letter isalway s S, forS ection. North-South sections are named using the local easting (e.g.S12000E, while East-West sections are named using the local northing (e.g. S9200N).

46 Tutorial 4: Geosoft Map Layer and Shape File

Angled sections use either the local northing or easting, depending on which is more perpendicular to the section azimuth. Locations are rounded to the nearest integervalue. Layers can be created in the current frame, or in individual frames asdemonstrated above for plan maps. Section layers can also include Name Tags.

Note that care must be taken not to load a section to an existing plan data frame, orvice-versa, because the coordinates are incompatible.

Quick Map - Load to a Single Layer

When Geosoft Map Layer s are loaded to a single layer the subsidiary views withinthe map are re-project ed into the master view. For example, if a section is createdwith a top plan, profiles and legend, the top plan portion, the individual data profilesand the legend are all re-projected and merged into the section view. This means thatthe coordinates one gets when placing the cursor over the plan portion are actuallystill the section coordinates, and data linking is not possible between the plan plot anddata, just between the section and the data. The same can be said for the plan map

plots. All subsidiary views (e.g. top section, legend) are merged into the plan view.

Loading Geosoft Map Layers and Shape Files at the same time

When you create multiple sections or plans, and shape files at the same time, andwhen you check the Shape Files box to Load to current data frame, the shape filesare automatically loaded to the correct data frame:

The Shape file lines, symbols and patterns plot on top of the Geosoft Map Layer layers.

Because of the nature of the frames created for Geosoft Map Layers, if you choose toAuto-load the shape files without also creating the Geosoft Map Layer s, the oneframe per section rule is not followed, and all the shape files will be placed into thesame, current data frame.


53/109

Tutorial 4: Geosoft Map Layer and Shape File 47

In other words, if you want to get Shape files from multiple sections to go intoindividual data frames, you must also have the Geosoft Map Layer box selected.

Frame/Layer Control for Stacked Sections

There is no Shape file output for the Stacked Section Plot.
