In the Design Properties menu bar type in a description (Always, always, always use a description). Click on theAttributes button to select a database type.

In the Design Type panel select Drilling from the Type dropdown list. The Desurvey Style drop down list allows you tospecify how the down hole survey was taken. It may seem like a small item but the desurvey style has the potential todramatically affect the location of the toe of your drillholes. If you are unsure of the desurvey style used during surveyingselect Tangent as this is the most generic method. Click 'OK' to return to the 'Design Properties' menu bar. Leave theData Source field as the default Isis setting.

Drillhole collar data and downhole assay data will be stored in tables within Isis. To create an Isis table select the menuoption Table > Insert. In the Table Properties toolbar enter Collar in the Name field. Type in a description (always use adescription). In the Synonyms drop down list select HoleId,Location. Leave the Source field blank.

Next we want to add tables for the assay and survey data. Do this by selecting Table > Append (the table showing theKey field should always be the first table on the left). Synonyms for the Survey and Assay tables are 'Survey' and 'Assay'

respectively. You do not need to enter the holeid field in these tables because it is assumed that the key field will appearin each table anyway. If you decide to add it to the table anyway thats okay too. The images below are examples of how Ihave entered the table data for the Survey and Assay tables.

If your ASSAY.csv file looks like this:

you should fill out the ASSAY table like this:

8/16

you should fill out the SURVEY table like this:

Under the Database section of this panel type in a name for the Isis filename. This name should not contain spaces. Topopulate the New Database Design field click the Select button (why no dropdown list and Browse button? I dontknow!). In the Select Design from which to Create Database panel select your design file from the dropdown list (why dowe need an entire separate panel to show a dropdown list and Browse button? I dont know this either!!). Click OK toaccept the values on these two panels.

The Specification save panel is intended to allow you to save all the settings you have just set to this point in the File >Import > CSV menu option. These settings can be reused to import data as long as you dont change anything in theimport process. In reality, I seldom want to import using the same settings and am often frustrated that the minoralterations I make to the process prevent me from using the saved specifications. I would recommend not saving yourspecifications. It is just a waste of time.

After clicking Finish your csv files will be imported into a new isis database. Click OK to exit the successful import paneland Cancel to exit the import panel.

To view your database in Isis click on the Start icon in the bottom right corner of the workbench and select Isis. This timeyou can select your database from the dropdown list in the Isis Filename field. Click OK. In the Isis view you can select aspecific drillhole from the dropdown field above the database tabs. Each of the tabs (COLLAR, ASSAY and SURVEY)holds different information about the database. The COLLAR field is usually pretty boring with just the x,y,z location

information. Take a look at the ASSAY and SURVEY fields for more information.
